02:57.43 rocko blrcad: how to set up the dev environment ?
04:37.25 brlcad rocko: did you see the wiki page on compiling?
04:38.03 brlcad install a subversion client for your operating system, install cmake, download brl-cad from our subversion repository, run cmake on it, then compile
04:38.07 brlcad ~cadsvn
04:38.07 infobot To obtain BRL-CAD from Subversion: svn checkout https://svn.code.sourceforge.net/p/brlcad/code/brlcad/trunk brlcad

06:33.19 brlcad Happy New Year everybody!
06:33.32 caen23 happy new year
06:57.09 Apra_ Yeah same to you brlcad, caen23
09:02.18 Apra_ I was going through homebrew cask github page where I saw many ruby source codes of different files...every other file had sha256 hash written..why are these hashes seen on every file?
09:17.24 *** join/#brlcad ARChak (~vircuser@117.214.43.90)
09:30.46 caen23 Apra_: they verify the hash of the downloaded installer against the hardcoded value, for both security (to make sure they downloaded what was intended) and for robustness (to make sure the file was downloaded and saved correctly)
09:32.30 Apra_ caen23: Can I ask how do you encrypt these...I mean whats the message that you encrypt to get these hashes?
09:34.34 caen23 there is no 'message', it's the bytes in the binary file
09:35.33 caen23 also, you don't encrypt anything, you compute a hash
09:36.20 caen23 encryption would require authorization, but a hash isn't really designed for that
10:48.10 Apra_ ohh

22:04.50 Apra_ So just thought of making it up for archer :)
22:07.45 caen23 the cask that's there (brl-cad-mged) is the dmg installer on sourceforge, which does include archer, even if it's not in the name

20:11.23 starseeker brlcad: that's pretty neat
21:51.34 Stragus Twice as fast as std::sort doesn't say much, if it's anything like qsort()
21:53.01 Stragus My SSE2 optimized radix sort is 5.25x faster than qsort()... or the hybrid sort is 1.58x faster
21:55.59 Stragus Eh, he's just using a radix sort and benchmarking against a comparison sort
23:01.23 starseeker brlcad: Testing here indicates the astyle formatting checking will now work, once we pick a format and go with it
23:02.02 starseeker might be worthwhile to teach astyle to use threading to check multiple files in parallel if we have performance problems, but right now it doesn't seem too bad

06:09.59 brlcad MikeH: excellent work
06:10.41 brlcad I thought I'd commented on the ebm issue being something not caused by you, hence the change being untestable -- that's how I knew you hadn't tested it.. ;)

My thought was that if we could snarf the libfo bits, make them more robust (based on initial testing with our FO intermediate files there's some work to do there) and hook it up with libharu to get a nice self contained C/C++ replacement for Apache FOP

22:18.33 caen23 my point was that it would help you more to learn how to find out the answers yourself
22:19.49 caen23 but the answer to this in particular is that some apps include an auto-updater (functionality that allows them to grab updates for themselves)
22:20.19 caen23 the flag you mentioned is set to true if the app in question has such a feature
22:20.38 caen23 brl-cad to my knowledge does not, so it doesn't need to be set
23:24.01 Apratim oh I get you...but caen23 how do you know that brl-cad doesnt have this feature...I mean how can I know that a program has this feature in it or not?Where shall it be mentioned?

05:39.18 karanagarwal17 Hey everyone! I am Karan Agarwal from India. I would love to contribute to the project.
05:39.56 karanagarwal17 My skills are HTML,CSS, JavaScript, Node.Js, Express.Js
05:40.28 karanagarwal17 I have also explored some libraries. Kindly guide me towards the right project for me.
05:43.14 brlcad karanagarwal17: best way to get started is to learn the tools, interfaces, websites, etc, and find something you want to fix or improve
05:44.08 karanagarwal17 I found the OGV project.
05:44.45 karanagarwal17 Currently i am installing it on my local machine
05:46.44 karanagarwal17 So, i would learn more about it and get back to you. :)
06:03.41 brlcad great
06:23.46 karanagarwal17 While i was installing the project , i ran into a problem. The meteor command did not work as it could not start the mongo server. I tried moving my source folder to home directory which is fat32 and it works. I am wondering why that happened and what i should do to make it run on ntfs system. I read somewhere i shold delete the mongod.lock file. But not sure what it does. Can someone help ?

12:29.39 d_rossberg it checks the magig number of a BRL-CAD struct, this way it tests an input parameter for the right type
12:33.17 d_rossberg i.e. you have either a type mismatch or an uninitialized structure

20:38.07 ``Erik hrm, scratch that, the x86 says the same thing, hopefully I didn't accidently put this thing in lil' endian mode
20:50.31 Stragus Playing on ARM?
20:56.07 ``Erik yeah, it's my new 'main' server, a rpi2 replaced the old thunderbird
20:56.11 ``Erik FreeBSD fenris 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r313175: Mon Feb 6 08:06:12 EST 2017 erik@rpi2:/mnt/da0s1/usr/obj/mnt/da0s1/usr/src/sys/RPI2 arm
20:56.41 Stragus I absolutely love ARM. Neon is wonderful
20:57.04 ``Erik O.o just a few years ago, you said arm was crap and it was all about amd64 :D
20:57.15 Stragus I said that? Darn :(
20:57.46 Stragus That was before I discovered Neon surely, but that still surprises me
20:58.19 Stragus NEON is everything MMX/3dnow!/SSE/SSE2/SSE3/SSSE3/SSE4.1/SSE4.2/AVX/AVX2 should have been... implemented properly right away, on the first shot
20:58.31 ``Erik iirc, we were chatting about server farms and your focus at the time was sse heavy C
20:58.44 ``Erik erm, and tons of x86 asm *shudder* :D
20:58.59 Stragus Eheh, so definitely before I discovered Neon
21:00.01 ``Erik I wonder how neon compares to, say, altivec
21:00.15 ``Erik (cuz altivec was everything that mmx/3dnow/sse*/etc was supposed to be)
21:00.54 Stragus Right... I read the Altivec docs but never used it. But Neon has some amazing stuff you won't find in Altivec either, as far as I know
21:01.02 ``Erik Stragus: one of the projects I'm sorta attached to has an rpi3 driving a tx1 in a mobile package O.o pheer
21:02.08 Stragus Neon can read a bunch of 16 floats (xyzw,xyzw,xyzw,xyzw), de-interleave and store in 4 separate registers (xxxx,yyyy,zzzz,wwww). And that's a... single cheap instruction
21:02.39 Stragus It's just fantastic, everything people need to do in real life
21:04.03 ``Erik interesting, but why not ship that to the gpu?
21:05.27 Stragus Sure, CUDA is also fabulous... 32-wide SIMD with fast scattered loads/stores, per-lane predicates and branching, on-chip shared memory, hardware switching to other threads whenever waiting for *anything*
21:05.30 Stragus CPUs suck :p
21:06.06 Stragus Still, in the realm of CPUs, ARM NEON does a pretty good job
21:08.04 ``Erik (I'm still saddened that the rpi is setting the arm to LE, and doubt the port is good enough to do BE)
21:08.53 ``Erik but it replaces a noisy powerhungry slow pos and seems to be doing a solid job so far, so *shrug* :)
21:08.59 Stragus I think the world is setlling on little endian, just like it settled on bytes being 8 bits
21:09.17 Stragus settling*
21:09.40 ``Erik bleh, VHS instead of beta, bluray instead of hddvd or whatever, ...
21:10.20 *** join/#brlcad kintel (~kintel@unaffiliated/kintel)
21:11.02 ``Erik I wonder if BRL-CAD will run on it... I bet it'll perform like complete crap in the benchmark :D
21:12.17 Stragus Eheh. I'm not aware of optimization advantages to big endian, perhaps I'm missing something...
21:13.07 ``Erik the only advantage of big endian is that I'm old and back in the day, the cool machines all used big endian, so now I'm sitting here shaking my cane and remembering the good old days
21:13.17 ``Erik y'know, make 'murika grrt agn
21:13.34 Stragus Oh, right, of course! :)
21:14.49 ``Erik the 'server room' is now very quiet, however, with the multiple fans and old 20g 5400 shut down, the only moving part is the pidrive
21:15.17 ``Erik which is basically just a laptop drive with some modified plugs and less case
21:15.18 Stragus is trying to think of any optimization only possible on big endian...
21:17.20 ``Erik the only real advantage is converting to/from network order (noop)
21:18.34 ``Erik iirc, even simple things like an adder uses a few less transistors in big endian, so there's a cost in silicon real estate... though the arm (and several other more modern chips) have switchable endian
21:18.41 Stragus I was trying to think of rather inherent advantages
21:19.49 Stragus Ahah, Google found something! memcmp() on big-endian is more efficient (assuming aligned pointers, etc.)
21:23.06 ``Erik when you do neon stuff, is that in asm, or is there an intrinsics package or api or something?
21:23.38 Stragus They have intrinsics. The compilers don't do a good job though, so people often rely on inline assembly
21:24.01 Stragus SSE/AVX has received more loving care in GCC than Neon
21:24.48 Stragus Have a look at arm_neon.h
21:26.36 ``Erik hm, not part of my clang distro :)
21:28.28 ``Erik not in the raspbian image, either... ah well, if I get to needing it, I'll find it
21:32.11 Stragus Feel the call of GCC, it's claiming for you

22:10.31 Sound brlcad: ping
22:17.01 teepee hey Sound
22:17.09 Sound hi teepee
22:17.55 teepee saw the mails, are you going to join gsoc?
22:19.00 Sound teepee: yeah!
22:19.23 Sound and the deadline for applying as organization is very close
22:19.59 teepee yep, it is, less than 2 days
22:20.09 teepee from our time zone pretty much tomorrow evening
22:20.24 teepee you have some projects to list?
22:21.32 Sound teepee: not yet, but I have plenty of ideas so I can prepare a list tomorrow morning (no later than 12 hours from now)
22:21.57 teepee cool
22:22.25 teepee it's important to have those structured with some rating for difficulty and such
22:22.59 Sound I'll take inspiration from the other CAx lists
22:23.25 teepee yeah, that's the simplest way :)
22:23.34 teepee main page is probably still http://brlcad.org/wiki/Google_Summer_of_Code/Project_Ideas
22:23.36 gcibot [ Google Summer of Code/Project Ideas - BRL-CAD ]
22:23.58 Sound I'd like to list both CG and non-CG tasks
22:24.00 teepee for us we reference our github wiki, e.g. https://github.com/openscad/openscad/wiki/Project%3A-Improve-OpenGL-rendering
22:24.00 gcibot [ Project: Improve OpenGL rendering · openscad/openscad Wiki · GitHub ]
22:24.47 Sound do I need to prepare the single task pages as well or the list is enough at this stage
22:24.47 teepee as far as I know the specific topic is pretty much free as long as it relates to the project and is actual coding
22:24.49 Sound ?
22:25.39 teepee not sure, I guess a slightly longer description might be useful
22:25.59 Sound okay
22:26.26 teepee we have that for a couple of the bigge tasks
22:26.45 teepee some smaller tasks just point to a simpler list
22:27.35 teepee should be fine as long as it has 1) description 2) skills 3) difficulty
22:27.43 teepee well, at least it was :)
22:27.51 teepee new gsoc, new rules
22:28.04 Sound good hint - and yes, I'll double check the rules :)
22:28.21 teepee yeah, need to do that myself
22:28.50 teepee they did also change things like the stipend for the students and such stuff which is not yet important
22:29.09 teepee so I suspect the rating rules have changed too
22:29.57 Sound hm I see
22:30.06 teepee but all that will come into play if we are actually accepted
22:30.29 teepee probably again lots of projects trying to join
22:31.50 teepee will LoH help too, I've seen he's helping quite a bit lately?
22:32.34 teepee having 2 mentor names listed would be a good thing too :)
22:33.55 Sound yeah sure, he confirmed he's willing to mentor :)
22:34.00 teepee nice

22:39.04 Sound …speak of the devil
22:39.21 LoH|Work Will be slightly distracted as I'm investigating some test failures (for work)
22:39.22 Sound hi LoH|Work, teepee and I were just talking about GSoC and you
22:39.30 LoH|Work D:
22:39.53 teepee indeed :)
22:40.10 Sound also waiting until Sean (brlcad) jumps into the conversation
22:40.14 LoH|Work Np
22:41.36 teepee is probably same timezone as Sound so not around for very long anymore ;)
22:41.55 LoH|Work Yeah, I'm US-CST timezone
22:41.57 Sound LoH|Work: teepee suggested we list 1) description 2) skills 3) difficulty for each task. I can work on a list tomorrow morning
22:42.02 LoH|Work GMT -6:30
22:42.07 Sound teepee: aha, I didn't know :)
22:45.45 LoH|Work Sound: btw you mind if I merge a couple simple fixes into master?
22:46.04 Sound LoH|Work: of course I don't
22:46.27 LoH|Work Sound: You'd indicated before you'd prefer to review everything is all :)
22:47.30 Sound LoH|Work: you're totally right, but 'simple fixes' sounds fine :)
22:47.34 LoH|Work I do think we need a better flow heuristic for smaller layer heights, btw
22:48.09 LoH|Work For UI patches I'll commit merge patches. If something goes awry, makes it easier to revert.
22:48.22 teepee shh :P
22:48.28 Sound teepee: sorry :P
22:48.42 teepee just reminds on the actual channel here ;)

22:50.51 LoH|Work or dead.
22:50.54 LoH|Work either/or
22:51.05 teepee if there's something coming up about gsoc, I'll be around tomorrow, maybe I even remember to join #slic3r when not being home
22:51.17 teepee hmm, did work a couple of minutes ago
22:52.06 Sound try to refresh several times, it worked for me after that
22:52.25 teepee news seems to hang for me but that redirects to facebook
22:53.05 LoH|Work ah, there it went the soc page
22:54.42 LoH|Work For Slic3r, we could certainly add a format parser to the list of project ideas
22:55.09 LoH|Work I've been meaning to look more closely into 3mf (since it has a GPL reference implementation)
22:55.23 teepee MIT
22:56.08 teepee yeah, having a nice list of projects is certainly a good thing, like brlcad mentioned about 10 looks good
22:56.09 LoH|Work teepee: for our purposes, close enough ;)
22:56.23 teepee probably not all need to be totally fleshed out in extreme detail
22:56.43 LoH|Work yeah, I can probably search the most-commented items out of our own tracker and sort a few out
22:57.18 teepee it should be work for like 10 weeks or so
22:58.33 LoH|Work teepee: yeah, some of them are relatively involved. Although some of them I'd never want in the codebase ;)
22:59.04 Sound LoH|Work: the GUI port from Perl to C++ is also a good candidate, students can learn C++ and wxWidgets without dealing with geometric algorithms
22:59.09 teepee haha, don't propose those I guess :)
22:59.29 LoH|Work Sound: Yeah, it's also been something I've been looking at taking for myself with some design docs.
22:59.49 teepee yep, that's probably a good candidate, although from our list of projects this type of task is not very likely to be chosen
23:00.14 LoH|Work Been trying to work out the design patterns to apply to the menu creation to keep it close to how the perl thing is
23:00.29 Sound In an ideal world, it would be very nice to share some code among those CAx projects. We all reinvented the wheel on many things :)
23:00.43 LoH|Work teepee: Rewriting our 3d system to use VBOs and more "modern" OpenGL would also probably suffice
23:01.28 Sound teepee: you mean students might not be interested? (Google doesn't approve the single proposals, right?)
23:01.38 teepee yeah, we have a similar task and even had one gsoc student interrested last year, but it did not happen in the end
23:01.54 teepee no, google is not much involved in the specifics of the project
23:02.21 teepee they do check the project listings but the details are totally up to you judgement
23:02.53 teepee your*
23:03.48 teepee in addition it's also ok if students propose their own projects - but that probably does not happen too often - and if so, it's like 2nd time students
23:05.47 Sound I see
23:06.17 LoH|Work Makes some sense, the GSoC is basically a giant RFP
23:06.43 LoH|Work Except that the people doing the work will be "funding" the grant
23:07.15 teepee yeah, and google is basically running the project and provide the stipends, the actual coding is totally up to the orgs
23:09.54 teepee I guess that works out relatively well as the org selection is strict and the mentors need to put in quite a lot of time, so it would be stupid from org perspective to really do a bad job
23:10.34 teepee so the biggest fear is that new orgs try to cut a piece of cake which is much too big - so there are some rules for that in place
23:11.31 teepee obviously it depends a lot on the student, but the rule of thumb is about 1 hour each day for mentoring
23:14.06 LoH|Work has a relatively low opinion on the productivity of students.
23:14.18 LoH|Work Probably from working with interns/co-ops here at work
23:15.29 Stragus It also seems to be quite a time drain for the mentor programmers
23:15.41 teepee one big part of gsoc is also to provide insight how open source projects work
23:16.19 LoH|Work teepee: Or don't ^^;
23:16.29 teepee so it's not like a payed intern - so far (which is 3 years with one student each) the motivation was always there
23:16.55 LoH|Work teepee: there's motivation and then there's capability.
23:17.29 teepee true, but that's also one of the hard jobs, selecting a student when participating as org/mentor
23:27.51 LoH|Work teepee: yeah very easy to believe there

19:53.18 Stragus Meh... As a first (free) open-source contribution in years, I attempt to give some 4000 lines of state-of-the-art SSE-optimized Kaiser-Bessel (ringing-free, sRGB-aware, etc.) image resizing to generate mipmaps that preserve/enhance details in SuperTuxKart's mipmaps
19:53.40 Stragus And they claim not to see much difference between old (left) and proposed new (right): http://www.rayforce.net/stk/testresizeoutput002compare.png o.O
19:54.34 *** join/#brlcad tandoorichick (~rakshika@60.243.170.241)
19:58.29 brlcad Stragus: heh, maybe try a higher-resolution sample (e.g., 2kx2k image) where it's really clear how blurry current method is vs new
19:59.04 brlcad elpea: sounds like you want the 'clone' command
19:59.33 Stragus Eh, yes... (come on, they use glGenerateMipmap() )
20:00.24 Stragus Anyhow, there's some good stuff in that code if anyone's interested, like sRGB-to-linear and back conversions with 0.01% accuracy in about 20 instructions (for 4 values if you use the SIMD path)
20:00.29 brlcad starseeker: definitely sounds possible ... though 7000+ pages in under a minute actually sounds a bit crappy :)
20:00.52 brlcad ``Erik: yeah, I noticed when the application was submitted -- expired to the day
20:01.04 Stragus Or rather, with an error of 0.01% rather than 0.01% accuracy :)
20:01.05 brlcad ``Erik: there's a script that will update it to a new version - have to find the instructions
20:01.32 elpea brlcad: thank you!
20:02.19 brlcad you're quite welcome -- let me know if you have any questions, though clone is pretty darn simple to use
20:03.16 brlcad Stragus: hehe, who doesn't love 99.9% inaccurate? :)
20:03.32 Stragus Yes, it sounds less impressive that way! :)
20:07.21 Stragus And that's the code if you guys need high quality mipmaps: http://www.rayforce.net/stk/imgresize.c http://www.rayforce.net/stk/imgresize.h
20:07.46 Stragus (or image shrinking in general)
20:11.47 elpea brlcad: just one for time being; any (easy) way to undo the clone operation?
20:12.25 elpea or should I dump the db prior to using it
20:19.20 *** join/#brlcad kintel (~kintel@unaffiliated/kintel)
20:22.12 brlcad Stragus: dear lordy that's a big file :)
20:22.40 brlcad looks interesting.. will have to see if this can integrate with our image processing library (src/libicv/size.c)
20:23.13 brlcad would probably rip out the mipmapping stuff -- the image resizing is more interesting bits
20:24.45 brlcad elpea: hm, dumping the db is probably reasonable
20:25.12 brlcad iirc, clone doesn't modify or even reference your original geometry, so you should be able to kill the entities it creates safely
20:25.43 Stragus brlcad: Right, you may want to keep only sRGB and linear resizing
20:29.50 elpea brlcad: alright, thanks
20:31.25 elpea thank god for killtree.
20:32.53 brlcad elpea: what are you working on?
20:33.21 brlcad Stragus: what would be one of the entry points to you code?
20:36.32 Stragus brlcad: http://www.rayforce.net/stk/imgresize.h
20:37.35 Stragus Other files in http://www.rayforce.net/stk/ , such as cpusimd.c for the SSE 4-wide sin(), stuff easy enough to copy/paste
20:37.35 gcibot [ Index of /stk ]
20:38.58 elpea brlcad: I got myself a 3d printer recently and am working on a lot of different hobby (and hopefully more) stuff. right now I'm making snap-on holders for my few dozen tools. I needed the clone command to duplicate such holder part for some diamond-coated miniature files, 2*5 rows.
20:55.31 brlcad elpea: neat -- got any pictures?
21:30.12 elpea brlcad: I'll upload some if I get this printed successfully tomorrow :) I've done some other stuff in brl-cad already, such as a small container box, GPIB cable cover and a garbage bag holder. nothing too fancy and I've only been CAD'ing for two weeks but I'm liking this particular software more and more every time I sit down to figure it out a little more :)

12:22.41 starseeker brlcad: yeah, I was a bit underwhelmed with that performance profile myself (7000 in < 1min) but most of the other text search systems I'm seeing are either license no-gos, very large and web-centric, or both...
12:24.06 starseeker and it's not clear to me how much work was done to optimize performance on that - the netbsd folks were probably not too worried about the db build time
12:25.09 starseeker we'd probably want our own db schema, but I figure that project probably has most of the necessary low-level bits in one form or another
12:29.16 starseeker and IIRC our current doc count is more like 700 than 7000, so it's probably worth testing first... might be a case of prematurely worrying about optimization
12:30.39 ``Erik if it actually matters, hitting it with a profiler might point out some obvious performance fixes in it O.o
12:30.48 starseeker their project is parsing the man page output... one possibility for us would be to use xslt to transform the docbook into something "easily parsable" for sqlite's FTS
12:31.14 starseeker ``Erik: true
12:31.46 starseeker also, their performance numbers are something like 5 or 6 years old now
12:32.25 ``Erik heh, wait, so you're worried about something that'll take less than 6 seconds on old hw during the build phase? O.o
12:32.49 starseeker no, but if it's 40-50 sec that's noticable
12:33.24 starseeker part of it's scoping - whether we index all of the tutorials and such as well as the man pages
12:35.00 starseeker part of the problem is that the index building will be one of the very last things the build does - it'll only be doable after all the man pages are built - which means any extra build time from that step is likely to get tacked on to the total rather than hidden in parallel building
12:36.27 ``Erik meh, it's build time... and if it's optional, who cares :D it's just (lumping sections into roughly similar build times, using the absolutely accurate "cuz it feels like" metric) building {docbook,openNURBS,step,everythingelse} to {docbook,apropos,openNURBS,step,everthingelse} :D
12:36.56 starseeker heh
12:37.18 ``Erik also; readable grammatical structure is for weenies. Push and recurse, yo.
12:37.48 starseeker I suppose it might be considered optional, but apropos would need it to work right

12:42.44 ``Erik nails gcibot to a wall

12:47.05 starseeker still trying to figure out what the command set should be
12:47.42 starseeker plus, our man pages are available in the GUI via the HTML output

12:48.05 ``Erik heh, I kinda wonder if there should be two sets that have different approaches... a user set and a developer set... trying to make a unified document system that serves both audiences smells complicated
12:48.32 starseeker nods - our dev docs will center around doxygen

18:15.09 Stragus Which does seem fine, but I would rather avoid having to write convex polehedron decomposition code
18:17.07 Stragus From the examples I saw, Bullet appears to resolve collisions after they have already occured; the solids overlap in space, then it pushes back so that they don't. That seems terrible when you have a big pile of colliding objects

19:43.07 imanoob Hello, does anyone here happen to have Solidworks on their computer?
19:43.07 imanoob I'd like to export some SLDPRT and SLDASM files to something usable by FreeCAD , because we use Solidworks 2005 at my school and I'd like to add something to an assembly, but I don't have Solidworks on this computer.
19:43.07 imanoob I saw by googling Solidworks can export to different formats (apparently STEP would be the best), so I was wondering if someone here could try to export/convert them for me please?

15:50.51 Sound kintel: what are the next steps? how to attract students, apart from announcing the thing in each project's channels?
15:51.31 kintel Sound: Btw., it would be interesting to have a look at how Slic3r and OpenSCAD could share some of the mesh analysis/repair code. That could be interesting for brl-cad as well.
15:51.37 *** join/#brlcad myra (329480f4@gateway/web/cgi-irc/kiwiirc.com/ip.50.148.128.244)
15:51.56 Sound kintel: definitely.
15:52.27 Sound kintel: we use admesh code, which we maintained and fixed
15:52.52 Sound kintel: however, I dislike using it for storing the mesh itself - which we do currently
15:53.26 Sound kintel: I'd like to move to a proper double-edge mesh library, and adapt admesh to work on it
15:53.30 kintel Sound: yup, + that admesh doesn’t fix some of the things we need to fix
15:54.33 Sound kintel: like nested shells or distinct shells some of which have inverse normals? what else?
15:55.10 LoH Oh, hello Sound
15:55.20 LoH ... I'm actually heading out to work now
15:55.20 kintel Sound: also, brl-cad had a related project last gsoc: https://brlcad.org/wiki/Google_Summer_of_Code/2016#Automatic_Polygonal_Mesh_Healing
15:55.20 Sound oh hello LoH :)
15:55.21 gcibot [ Google Summer of Code/2016 - BRL-CAD ]
15:56.02 kintel Sound: admesh doesn’t remove zero-area triangles
15:56.30 Sound kintel: ah okay, that's not an issue for Slic3r apparently
15:56.40 kintel admesh also cannot repair collapsed volumes
15:57.09 Sound collapsed = zero volume?
15:57.16 kintel example of collapsed volume: https://cloud.githubusercontent.com/assets/186094/5779656/9cf36078-9d72-11e4-8b5c-e5e418e25097.png
15:58.00 Sound I don't get it fully, is that basically two volumes one of which has negative volume?
15:58.43 kintel the second has zero volume
15:59.05 kintel but it’s a single mesh - i.e. it’s not manifold
15:59.27 kintel this happens when snap-rounding to float from a higher-precision source
16:00.07 kintel (perhaps hard to see from that blender screenshot)
16:00.16 Sound yeah, so that's what I mentioned before. admesh will probably split that into two distinct shells by adding the redundant edge(s), but when deciding whether to reverse all the normals or not, it calculates the full volume, and reverses everything it it's negative - instead of doing that on a per-shell basis
16:00.37 Sound if* it's negative
16:01.06 kintel If it would correctly split it into two shells, the rest would be pretty easy to cull
16:03.10 kintel anyway, I’d love to see a clean library with a mesh class where various such repair/cleanup/healing functionality would be implemented. admesh looks a bit hard to massage into such a library, but there are lots of good ideas there (+ his thesis)
16:03.57 Sound I totally agree
16:04.05 kintel there was a bunch of discussion on this topic on the openscad mailing list. ..including someone who went on to implement such a tool which has proven to work well, except he didnt
16:04.09 kintel <PROTECTED>
16:04.34 Sound heh
16:04.56 Sound speaking of GSoC, how do you advertise it now?
16:05.21 Sound or no need to?
16:05.30 kintel We’ve usually just advertised it on social media, website and personal networks
16:05.48 kintel ..but that hasn’t really attracted much attention. Most applicants tend to find us from the gsoc site itself
16:07.25 kintel I think in particular the university in Hyderabad India is specializing in gsoc applications
16:08.40 Sound ah, I see, then no need to work much for getting students
16:11.40 kintel Sound: The challenge is to attract the more competent/experienced students
16:12.02 kintel d_rossberg: Did the student you mentored on mesh healing last year produce useful results - is that something we could build on going forward?

10:55.03 gabbar1947 brlcad: all i can figure out now is that , 4D coordinates are nothing but the 3D coordinates transformed from euclidean to homogeneous coordinates and HCROSS() will basically return the cross product of those 3D points with the fourth coordinate as 0 coz, as such the cross product of two 4D vectors doesnt exist. Do you feel this is in the right direction ?

02:48.47 brlcad Hi Alvis, don't be shy ;)
02:49.08 brlcad thanks for the intro and thrilled to hear about your background and interests
02:49.26 brlcad Alvis: were you the one that e-mailed me a while back
02:49.46 Alvis Yes
02:50.08 Alvis I've checked out brl-cad a couple of times and couldn't find you, so I've decided that email might be a better means of communication
02:50.40 Alvis and now I've finally got a irc desktop client so it makes things much easier now :)
02:51.06 brlcad getting in touch can be ad hoc -- just reach out any and every way possible
02:51.10 brlcad you'll get someone's attention ;)
02:51.39 brlcad irc usually works best, but you got to stay connected or use something like 'irssi' with 'screen'
02:51.58 Alvis haha sure :) I've emailed brlcad-devel if that's what you're talking about
02:52.03 Alvis Oh I'll check them out
02:52.08 brlcad that works
02:52.13 brlcad screen is a persistent terminal
02:52.27 brlcad irssi is simply a console irc client (which you can run in a screen session)
02:52.45 Alvis like for 'screen' it never disconnects and keeps fetching messages?
02:52.46 brlcad which basically gives you irc 24/7 that you can get to anywhere if you run it on a server
02:52.52 brlcad right
02:52.55 Alvis ohhhhh nice
02:53.10 Alvis That's exactly what I've been looking for years lol
02:53.30 Alvis but didn't spend much time in research cause I only use irc for open source communications :p
02:53.54 brlcad yeah, open source tends to dominate irc these days ... open source and a few games
02:54.23 brlcad so have you done any opencl coding before?
02:54.34 Alvis Anyway regarding the OpenCL project, I have experience in CUDA and my research project is on numerical analysis, solving equations for graphics
02:54.41 Alvis not opencl but cuda
02:54.48 Alvis but I'm a quick learner ><
02:55.01 Alvis and I love learning :)
02:57.09 brlcad what kind of cuda work have you done?
02:57.39 brlcad and what do you mean by solving equations -- which equations? :)
02:57.45 Alvis Navier-Stokes
02:57.53 Alvis the pressure equation ><
02:57.57 brlcad nods
02:58.21 brlcad so fast fluid simulations of some sort?
02:58.25 Alvis yea
02:58.34 Alvis graphics simulations for water and stuff
02:58.44 Alvis My prof has been guiding me to explore various solutions and compare their performance
02:59.09 Alvis So far the simpler ones including Jacobi, Gauss-Seidel and Conjugate Gradient
02:59.24 Alvis and tried out different memory options such as matrix-free, csr
03:00.29 brlcad lots of iterative methods
03:01.07 Alvis yup, so far we've been trying to figure out ways to adopt CUDA architecture and optimize the iterations as much as possible
03:01.13 brlcad so cool .. ever done anything with ... nurbs? :)
03:01.35 brlcad (specifically solving nurbs equations)
03:02.33 Alvis nah... :/ I'm new to graphics, fortunately and thankfully my prof trusts me to be self-motivated enough to learn all the necessary prerequisites
03:02.49 brlcad no worries, that's what I would expect ;)
03:03.23 Alvis ahh I see from wiki "NURBS are commonly used in computer-aided design (CAD), manufacturing (CAM), and engineering (CAE)"
03:03.30 Alvis nice, I feel relieved~
03:04.21 brlcad if you want some "light" reading .. https://pdfs.semanticscholar.org/958e/9bc11f07badda0258c9fc9081704d3185da5.pdf
03:05.00 brlcad and http://www.me.berkeley.edu/~mcmains/pubs/CAD09KrishKhardMcMains.pdf
03:05.41 brlcad so what are you interested in?
03:06.15 Alvis actually... just curious... what level university are GSoC projects intended for, I saw OpenCV has a project that says "don't even think about doing this project unless you're a phd who has an expertise on this area"
03:06.20 brlcad you mentioned the gpgpu opencl ray tracing, any particular aspect -- what do you know about ray tracing?
03:06.40 brlcad project requirements span the gamut
03:07.10 brlcad we have some projects that are more appropriate for a PhD and others that are good for students with just a year or so experience
03:07.23 Alvis ahh ic
03:08.08 Alvis I've only had some introduction into ray tracing and graphics simulation, I encountered the term when I'm trying to learn about animation graphics
03:08.59 Alvis I've been exploring around various areas that spread across the spectrum, cause... rarely could I find opportunities to have some amount of guidance to help me learn more efficiently and effectively
03:09.21 Alvis Usually if I read tutorials on my own it takes a much longer time, and things are much easier to get stuck ><
03:09.41 brlcad so I would recommend you do three things to figure out what to do next
03:10.24 brlcad 1) compile and install brl-cad from source, learn enough to model a sphere and ray trace it using BRL-CAD tools
03:11.21 brlcad 2) look at the 2015 GSoC GPU work, maybe even try to compile and run it (it's in an svn branch), read through the dev log and understand the gist of what he did
03:11.53 brlcad 3) look at the 2016 GSoC GPU work, understand how it relates to the 2015 work and how far he got ... what worked and didn't
03:12.25 brlcad that should all be doable in just a few hours
03:12.27 Alvis Sure, thank you!
03:13.07 brlcad and it will give you a really strong practical understanding of where things are, what we're trying to do, and how we're going about it
03:13.55 Alvis yuppp
03:14.13 brlcad then you'll be in a good position to propose what you might want to do
03:14.55 brlcad whatever you propose, it should fit into our bigger picture in some manner, either being a continuation of prior work or tacking a piece not yet tackled
03:16.52 brlcad the 2015 effort attempted to hit the whole pipeline and got 80% there -- it got some really basic spatial partitioning (how you march a ray through a scene) and opencl-accelerated intersection testing for a half dozen object types (how you determine whether/where you hit something)
03:17.28 Alvis wow, this is really interesting
03:18.54 brlcad the 2016 effort tackled part of that 20% missing, boolean evaluation (weaving segments to evaluate CSG logic for final processing before hit points are turned into an image)
03:19.23 brlcad neither effort finished, but HUGE progress has been made
03:35.47 Stragus looks forward to giving tips and feedback on writing high performance GPU code
03:39.23 Alvis :DDDDD
03:41.21 Alvis I feel so hyped with all the experts in this channel :DDD
04:16.02 brlcad Alvis: so I think the next step are those three things mentioned and see what you think
04:16.48 brlcad you're probably going to have a lot of new concepts getting thrown at you, so just take your time and absorb what you can, ask questions if needed (and wait here for the response)
04:16.52 brlcad someone is always here
04:17.13 brlcad answers may come minutes/hours/days later (usually not days though)
04:17.23 brlcad seconds even
04:18.05 brlcad once you have a feel for what's what, next would be to try making a modification like what vasco suggested on the mailing list (converting a primitive to opencl, for example)
04:18.52 brlcad that will then be a whole other challenge, learning to navigate a huge existing codebase with thousands of features, cobwebs and gemstones at every turn

05:45.46 brlcad xfactor: which mailing list did you subscribe to?
05:46.20 brlcad logged IRC (on 24/7) and joining the brlcad-devel mailing list is generally what I would recommend

Check for a null idata after the call - untested, but this may avoid the screengrab crash reported

21:18.43 d_rossberg then let subversion create the patch file
21:20.59 d_rossberg e.g. "svn diff > patch_file_name" should do it

08:54.26 elpea I used clone to generate a spiral screw structure from thin rpp's which I grouped together. I can convert this to stl just fine using 0.001 absolute tessellation but when I add a cylindrical solid axis in the middle and create a region by doing union on the group and the axis, g-stl.exe exits with "Dangling faces detected in rA after boolean" ... I tried to google this error without getting much wiser. any advice?
08:56.17 elpea there are 1440 said thin rpp solids total, plus the axis rcc
08:58.18 elpea I tried to elongate the axis so that its dimensions went beyond the spiral structure in both ends on Z axis, but this didn't help
09:00.46 elpea the rpp's dimensions are 50 0.5 0.5, and the spiral structure is made with 720 clones with 0.5 rotation and 0.1 elevation (Z) increments
09:02.20 elpea with no translation on other axes besides Z (so everything stacks at 0 0 0, and of course there is a lot of overlap between the solids)
09:04.04 elpea the axis has a radius of 5 and resides in the middle (0 0 0)
09:06.43 elpea on another topic: is there a way to select the parameters to edit directly from CLI? I find it a bit tedious to pick e.g. an edge to edit using the GUI... I know you can do this with keyboard, but it's still clunky.
09:16.22 *** join/#brlcad teepee (~teepee@unaffiliated/teepee)
09:20.00 elpea another feature request(?): it would be nice if the CLI colorscheme was configurable, or at least invertable. I often work at night so I really need a dark background.
09:22.33 elpea since I already started bombarding with questions; how is the multicore support in BRL-CAD/MGED? I'm looking to upgrade my rig at some point and have been considering Xeons to replace my i7.

09:57.23 elpea ok... "solved". for reasons unknown to me, the conversion succeeds if I group the rpp's comprising the spiral structure with the axis, instead of regioning the spiral and the axis together separately.

17:23.17 gabbar1947 afaik, no special parameters were used to generate it
17:24.12 gabbar1947 Ill generate the patch again
17:27.31 d_rossberg see for example here for a discussion of the format and why I consider it as suspicious: http://stackoverflow.com/questions/987372/what-is-the-format-of-a-patch-file
17:27.31 gcibot_ [ What is the format of a patch file? - Stack Overflow ]
17:29.26 d_rossberg ... ,7 ... ,7 ... means that there are same number of lines in the old and new file which shouldn't be true
17:34.05 gabbar1947 I get it. give me a second ill update the patch
17:36.28 gabbar1947 d_rossberg : UPDATED
17:40.26 d_rossberg now it worked :)
17:45.08 gabbar1947 cheers !
17:46.37 gabbar1947 I've updated the geom.h. Do you want me to put the patch now or should I put it after completing annotation.c ?

17:49.50 d_rossberg upload it as a patch on sourceforge, this way we can discuss it
17:50.11 gabbar1947 Oh fine!
17:51.21 gabbar1947 Do you want the structs for line_seg, curves, circular archs etc. to be defined again with some updated parameters, or would it be fine to use the ones that are used by the sketch and the extrude primitive ?
17:57.31 d_rossberg you could use the ones from the sketch, but why the updated parameters? (you can explain it in your patch)
18:02.47 d_rossberg gabbar1947: have you tested rt_ehy_centroid()?
18:03.32 gabbar1947 well I did, Is there any issue that's occuring ?
18:03.42 d_rossberg how?
18:04.43 gabbar1947 brute force, took points with defined results
18:05.24 d_rossberg no, i meant how did you call rt_ehy_centroid()?
18:07.09 gabbar1947 Oh ! I took it the other way, well, apologies but didn't test it this way
18:07.15 gabbar1947 Will do , no issues
18:09.37 d_rossberg you could try to use analyze (src/libged/analyze.c) to call rt_ehy_centroid() and rt_ehy_centroid()
18:11.05 gabbar1947 sure, ill do it and get back to you. Is it giving undesired results ?
18:12.03 d_rossberg try it by yoursef ;) (it gives no result but a kind of error message)
18:13.02 d_rossberg maybe analyze_general() will do the job in analyze.c
18:14.15 d_rossberg or maybe not, volume is missing

18:14.28 gabbar1947 gracias, will do as required
18:15.42 gabbar1947 I was working on the volume too, didn't get any satisfying proofs for my definition, hence work is at stall ;)
18:17.19 d_rossberg the centroid looks good so far, i only wouold like to see it in action
18:18.02 d_rossberg on a second sight analyze_general() could work even so

18:23.33 gabbar1947 One more regarding the 3D to 2D transformation. Where exactly should the transformation function be defined, so that I don't put it in an undesired place ?
18:28.00 d_rossberg good question, i would say somewhere near the transformations from the combinations
18:28.15 d_rossberg i haven't looked for the perfect place yet

01:21.36 starseeker brlcad: I was thinking that myself (it belonging in bg)
01:22.45 starseeker I want to study it a bit more to understand what benefit it's bringing - when I've dealt with bots in the past I've always manually managed the indexing into vertex arrays for faces
01:23.32 starseeker I'm hoping that was stupid and this code is designed to make that easier, but I'm still feeling under the weather (got into some bad food over the weekend) so I don't trust my brain right now
01:25.01 starseeker sorry about the over-renaming - you might want to check the CHANGES replacement expressions. I probably shot too much from the hip, but the Add_vert was annoying me in the CREO code because I kept thinking it was a CREO function instead of ours

11:25.27 DaRock Hi guys
11:25.41 DaRock is brlcad capable of modeling threads?
11:26.21 DaRock I don't seem to be having much luck with any opensource cad apps
11:27.06 archivist look for cut along a helical path
11:27.36 DaRock heres the catch - does it actually work though?
11:28.24 DaRock I've been trying with FreeCAD and it either crashes or the convoluted procedure fails
11:28.48 DaRock apparently it is a hard trick to do, and openscad has issues as well
11:30.05 DaRock ran a search on google re brlcad with non definitive results, so I'd like to be sure before running more dozens of hours chasing a goose
11:32.55 Stragus I can't document the process, but I certainly saw models with tracks made in BRL-CAD
11:33.21 DaRock tracks?
11:33.39 Stragus Threads, sorry
11:34.04 DaRock fwiw google search for brlcad cut helical path still comes up nada - first result is for solidworks (??)
11:35.06 DaRock hmmm. Looks like another learning curve is coming then if you're sure of those tracks... threads :)
11:40.49 archivist another solidworks type term extrude a face/sketch along a helical path
11:42.16 DaRock another is helical sweep
11:43.04 DaRock FreeCAD uses a helix primitive, then runs a sweep and then cuts it :)
11:43.15 DaRock difference is just marketing ;)
11:43.47 archivist not really as some are additive and others are cuts
11:44.59 DaRock only depends on whether you want to cut or union - philosophical really... :)
11:47.01 DaRock the naming is all marketing though... heaven forbid they should use a similar term!

05:38.55 DaRock nmz787: thanks for that. Combining brlcad and python? I didn't realise it was possible
05:39.49 DaRock why crude though? You can't change the extrusion shape?
05:40.36 DaRock elpea: is that a formula driven parametric curve?
05:41.42 DaRock right now I'm missing libpng library - mged and archer worked in the build dir, but came up with error after install
05:42.06 DaRock anyone know where I can tell it to go?
05:57.06 nmz787_ DaRock: you're compiling?
05:57.20 DaRock no, running
05:57.28 nmz787_ I mean, you compiled this build?
05:57.37 nmz787_ or just downloaded already built binaries
05:57.42 DaRock as I said, it ran from the build dir, but not after install
05:58.02 nmz787_ did you strace it?
05:59.10 DaRock its a shared object its not finding - its obviously looking in the wrong place
05:59.25 DaRock except it finds it when run from the build dir
06:00.43 DaRock confusing
06:12.11 DaRock if I set LD_LIBRARY_PATH it tells me that the file format is not right :/
06:14.26 DaRock sorry, thats a 32bit compat
06:14.46 DaRock but still baffles as to why it ran from the build dir
06:25.35 nmz787_ did you try a new shell?
06:25.44 nmz787_ or logout and log back in?

07:15.44 DaRock this is frustrating me... urt is no longer available, but it is apparently builtin to brlcad - is there anyway to compile in a hybrid fashion? use the urt builtin, but use system libraries for the rest?

00:34.27 starseeker DaRock: there is a way to do hybrid
00:34.57 starseeker if libpng is the problem, override with (iirc) -DBRLCAD_PNG=SYSTEM
00:35.03 starseeker when configuring with CMake
00:35.59 starseeker generally speaking, you get the situation you're describing when system libraries are used that depend on the system libpng15, but BRL-CAD's libraries are also built using our bundled libpng16
01:39.27 DaRock thats strange. My system is using libpng16, and brlcad is building libpng15. I'll try that and see if it helps anyway. Thanks
02:22.00 DaRock I'm getting a different error as well: error: Tk 8.6 must be compiled with tcl.h from Tcl 8.6 or better
02:23.07 DaRock no diarrhea on this one. Googling is not exactly revealing any answers either...
02:41.56 starseeker DaRock: does doing -DENABLE_ALL=ON help?
02:42.42 starseeker DaRock: which version of BRL-CAD are you building? our trunk build has 1.6.23
02:43.10 DaRock don't know... I'll have to give it a go. What does that one do? And where are all these knobs documented?
02:43.37 starseeker DaRock: if you run cmake-gui and do a configure you'll see them listed in the GUI
02:44.07 starseeker there's also the top level INSTALL file
02:44.31 starseeker ENABLE_ALL uses (as much as possible) the src/other versions of libraries
02:44.59 DaRock honestly no idea - I'm building out of freebsd ports system, as it helps with most stuff on the system, but this particular port is deprecated and refuses to build without urt - which is unavailable anymore. So I found that urt is incorp in brlcad anyway, and trying to get it to build.
02:45.18 starseeker ah
02:45.28 starseeker ``Erik: any ideas on this?
02:46.08 DaRock Seems to succeed, except for the png issue - runs from the staging dir but not once installed. builtin libpng seems to be in the stage area (libpng15), and doesn't get installed obviously
02:46.09 starseeker no wonder you're not using ENABLE_ALL - an integrated OS build usually doesn't like doing that
02:46.47 starseeker -DENABLE_ALL=ON -DBRLCAD_PNG=SYSTEM -DBRLCAD_ZLIB=SYSTEM might work
02:46.50 DaRock I have been fiddling, so maybe it was in the original and got wiped somewhere too :)
02:47.12 starseeker (if you're going with system png you almost always want system zlib too)
02:47.19 DaRock but where are the knobs located - I always seem to get stuck on a cmake system :)
02:47.27 starseeker nah - the OS guys hate that we bundle libs
02:47.39 starseeker it'a a major sticking point for Fedora/Redhat
02:47.43 starseeker Debian too, iirc
02:48.11 starseeker DaRock: the knobs are suppled to the CMake command line
02:48.15 DaRock if urt is needed, I can't see the complaint. Buuut... we'd be better off using the system libs as much as possible
02:48.21 starseeker if you prefer, you can try the configure wrapper script
02:48.38 DaRock I know that :) but where are they documented?
02:48.44 starseeker INSTALL
02:48.47 starseeker top level text file
02:48.54 starseeker in the source tree
02:49.11 starseeker starting about line 345
02:49.44 DaRock I'll have a look then. Will enable_all still use the builtin urt though?
02:49.55 starseeker yes
02:50.01 starseeker it uses built in everything by default
02:50.38 DaRock I think I might try and find an original copy that Makefile then - I think I've screwed up somewhere :D
02:50.59 DaRock then I can simply comment out the urt dependency
02:51.07 DaRock see how that goes
02:51.27 DaRock but at least I'll have the right starting point
02:51.37 starseeker if ``Erik pops in, he's our BSD expert
02:52.05 DaRock then I can take good look at all those knobs and see what will tickle its fanny enough to get it running
02:52.36 DaRock thanks for the help with this starseeker - Erik's probably our porter

10:56.51 starseeker DaRock: I'm not actually sure that bit is working properly
10:57.14 starseeker (TERMLIB_INCLUDE_DIR)
10:57.30 DaRock so.... what? :/
10:57.56 starseeker I'll see if I can look into it later today, unless you want to tackle redoing it :-)
10:58.05 DaRock I'm looking at the source, and it should fallback to curses... etc
10:58.12 starseeker what are the symptoms you're seeing?
10:58.18 DaRock not a clue where to begin :)
10:58.28 starseeker I didn't have one either when I started
10:58.50 starseeker not always sure I have one now, for that matter ;-)
10:58.51 DaRock I'm still on the first steep learning curve :)
10:59.24 starseeker it's actually pretty straightforward, especially compared to autotools
10:59.55 starseeker misc/CMake/FindTERMLIB.cmake should be involved with all that
10:59.57 DaRock so I'm building on freebsd - mangling the port - trying to disable the builtins so the tk and libpng errors go away, but keep the urt lib
11:00.24 DaRock it fails on finding termlib
11:00.40 DaRock although why CMake should even need to get involved....
11:00.57 DaRock the c file seems to handle it very gracefully
11:01.17 starseeker CMake sets the defines
11:01.26 starseeker (or should be)
11:01.35 DaRock src/libcursor/cursor.c
11:01.44 DaRock weeellll....
11:01.44 starseeker the main logic is in src/other/CMakeLists.txt around line 202
11:02.15 starseeker and the THIRD_PARTY macro that calls is in misc/CMake/ThirdParty.cmake
11:02.24 DaRock have a look at the c file - it seems to do well enough without. Unless you specifically want the builtin
11:02.58 starseeker which is one of the cases we need to handle (deliberately turning on the built-in)
11:03.21 starseeker if all else fails we fall back to the built-in, which is why we need to fix the detection
11:03.57 DaRock seems fraught with difficulties :|
11:03.59 starseeker FindTERMLIB.cmake should be checking for curses, ncurses, etc.
11:04.38 starseeker DaRock: it's a general principle of the BRL-CAD build - the default out-of-box build will use system libraries where it can and src/other versions where it can't
11:04.55 starseeker you can also override to use only src/other versions and only system libs
11:04.58 DaRock I get that, but it doesn't seem to work
11:05.44 DaRock overrides don't always work either - but where do I tell it to override termlib then?
11:06.03 starseeker it gets tricky when you have system versions getting pulled in and locals enabled - the most common are zlib and png being enabled due to dev packages not being installed, but other system libs pulling in the system versions as well
11:06.31 starseeker DaRock: it sounds like it's not detecting the system version correctly, so it can't work as expected
11:06.32 DaRock exactly
11:06.40 DaRock exactly
11:06.55 starseeker I'll see if I can figure out why that detection isn't working - that should be the fix
11:06.58 DaRock I don't quite know why though
11:07.26 DaRock but again, why isn't there a knob for it? There is for just about everything else
11:07.59 DaRock then if it isn't working as expected, it can be overridden and we move on in the meantime
11:07.59 starseeker did you try -DBRLCAD_TERMLIB=BUNDLED ?
11:08.24 starseeker that's what I would expect to be the override
11:08.27 DaRock really? Where's that?
11:08.56 DaRock I was hoping I could do SYSTEM, but I'll see...
11:09.24 starseeker if it can't successfully detect the system version in the first place it won't let you succeed that way
11:09.36 starseeker the "safe" fallback is to use our termlib
11:10.12 DaRock from the logs, I'd say it isn't even looking for anything other than termlib (which the c file could handle) and simply failing
11:10.16 starseeker DaRock: to be honest, we haven't put a lot of energy into the termlib stuff because it's eventually all scheduled to go away - we *can't* use it on Windows without an insane amount of work, and most of the tools that need it are very old
11:10.45 DaRock thats my thinking :)
11:10.46 starseeker OK, so something about FindTERMLIB.cmake isn't working right - it either isn't being called at all or its not doing its job
11:11.08 DaRock the override won't work you think?
11:11.10 starseeker i'll see if I can dig into it later today
11:11.20 starseeker the override -DBRLCAD_TERMLIB=BUNDLED should work
11:11.28 starseeker it just won't use the system version
11:11.47 DaRock why? <sigh>
11:11.55 DaRock retorical btw
11:12.10 starseeker because our src/other is the fallback - we can't always rely on the system to provide what we need
11:12.16 DaRock yes I miss-spelt it
11:12.24 starseeker if the world consisted only of Linux and BSD distributions, we probably could
11:13.00 starseeker but Windows, OSX, etc. don't have anything to match (say) the Debian apt system
11:13.06 DaRock yes but why can't I - the compiler - tell it and to hell with the consequences?
11:13.20 starseeker you can - -DBRLCAD_TERMLIB=SYSTEM
11:13.40 starseeker but it will still have to detect the correct library flags and include dirs, and if it can't find them successfully it's game over
11:14.05 DaRock I get that - and compiling it for one's self _should_ be the option, but I should still be able (if capable) to tell it what I want, rather than automated
11:14.18 DaRock fine - build fails
11:14.58 DaRock if I don't know what I'm doing, then I fallback myself to the automated system. If I can resolve it, then all will eventually be ok
11:15.05 starseeker if you REALLY want to get hardcore you can define the things the FindTERMLIB file is supposed to define as well... -DTERMLIB_LIBRARY=curses and -DTERMLIB_INCLUDE_DIR=/usr/include or something like that
11:15.33 DaRock it sounds like its born from an out of the box mentallity
11:16.04 starseeker so -DBRLCAD_TERMLIB=SYSTEM -DTERMLIB_LIBRARY=ncurses -DTERMLIB_INCLUDE_DIR=/usr/include may get you past it in combination
11:16.44 starseeker very much - the goal is to have the configure step always Just Work regardless of any shortcomings of the build environment
11:16.55 starseeker (to a point of course - we can't bundle X11)
11:17.12 DaRock thats what I was thinking, but it doesn't seem clearly indicated - it only says the defines, and none of the acceptable options are listed
11:18.17 starseeker well, you shouldn't be having to defined the TERMLIB_* variables yourself - that's a bug in our system
11:18.18 DaRock and thats fair enough, but to cut out any manual stuff is sure to come unstuck in edge cases where control might be required.
11:18.38 starseeker nods - and in those situations, you can dig down and hand set variables
11:18.59 DaRock I'll try those defines and see how I go - now that I know whats what ;)
11:19.54 DaRock yes, but those variable are not documented as to what values can be put, or how the variables can be used - digging down didn't help :)
11:20.00 starseeker DaRock: fwiw, brlcad is usually more in your camp of minimizing the "magic" and requiring manual setting of things to avoid broken corner cases
11:20.47 starseeker DaRock: that's a fair point, and we probably should update our INSTALL doc to document what variables need to be hand-set if a manual override is required
11:20.58 DaRock starseeker: does ncurses work on windows?
11:21.10 starseeker nope
11:21.42 DaRock works on about all others though, I think... I thought it did
11:22.49 starseeker the closest thing out there that I know if is a version of pdcurses: https://www.projectpluto.com/win32a.htm
11:22.49 gcibot_ [ PDCurses modified/extended ]
11:22.58 DaRock no don't - that should be one to search for, but update it in the FindTERMLIB cmake file. If you don't dig that far, then you probably in the wrong place :)
11:23.11 starseeker but I think the parts of the API they implement generally aren't the ones we use
11:23.23 DaRock does brlcad use cygwin or is it native?
11:23.27 starseeker so we'd have to rewrite a lot of our termlib code to more properly target the curses api
11:23.39 starseeker it's native, built with MSVC
11:23.49 starseeker one of the reasons we use cmake
11:24.18 DaRock so win would be the edge case :D
11:24.26 DaRock :P
11:24.31 starseeker yep. also, unfortunately, the most common today
11:24.57 starseeker BRL-CAD far predates Windows, so to us it's still an annoying edge case, but the rest of the world hasn't caught up yet
11:25.19 starseeker DaRock: insider trick - look in .cmake files for the FIND_PACKAGE_HANDLE_STANDARD_ARGS line
11:25.21 DaRock lol tell me about it :)
11:25.48 starseeker in fairness, Windows is a lot easier to deal with these days than in years past
11:25.52 DaRock thanks for the tip
11:26.12 starseeker that macro defines the "required" variables for a particular Find*.cmake file
11:26.44 DaRock <barf>... sorry about that. Thats why I got away from it entirely over 10 years ago
11:26.46 starseeker if hard-setting the TERMLIB variables doesn't get you past it I'll try to see what's going on with the FindTERMLIB logic
11:26.56 starseeker heh
11:27.33 starseeker we periodically try to eliminated special case WIN32 logic in the build and code, but there's still quite a ways to go
11:27.41 DaRock I got jack of having to explain why I had to reinstall it because some damned virus totalled my system
11:27.52 starseeker yep, that gets old
11:28.07 starseeker they're doing a lot better today than the Windows 98 days though.
11:28.39 DaRock so I gave them one last call, and switched to linux, then bsd - and run it entirely caged in a vm if I really really have to
11:29.00 starseeker nods - virtualbox and qemu really make life easier in that regard
11:29.05 DaRock win98 you didn't have to justify a reload though
11:29.20 starseeker heh - true enough
11:29.38 starseeker DaRock: OK, I've gotta run - let us know how it goes and whether you hit any other hurdles
11:30.21 DaRock I'll have a quick look at the FindTERMLIB logic, but my time is well overrun on this project so I might not get much done - I'll let you know what if I find anything
11:30.34 DaRock sure. Thanks for the help :)

11:29.37 DaRock starseeker: I'm spinning here, can't quite get my head around it. FindTERMLIB has some real quirks in it - I don't get the cmake stuff enough yet, but what appears to be happening is I get successes and finally a fail on a missing LIBTERM_INCLUDE_DIR. What I don't get is where the fail is happening exactly
11:33.24 DaRock starseeker: and here's why - firstly, the variable is set (correctly); and secondly, the logs indicate yet a different issue entirely. When it runs a test compile to see all is well, it still looks for libterm! And it succeeds as far as I can tell. I ran the compile manually myself to see - couldn't do the cmake particular stuff though so maybe thats the failure. BSD has libtermlib.so so thats probably why
11:35.08 DaRock starseeker: so if its in the system already, there'd be no need for the builtin anyway - except it can't seem to find it. But I'll buggered if I can figure out a patch yet :)
11:41.26 DaRock starseeker: actually one thing has struck me - I don't see anywhere that the automation can even be overridden. It looks like it ignores any input in that area and _only_ tries to determine it itself. Which might explain why it finds the system termlib and goes with it - but doesn't check the others - and then failure means it fallsback to the builtin. But why the fail when everything seems to succeed?
11:42.53 DaRock starseeker: last piece of info, that I'm not sure about and have little to go on with, is in the logs after the last test compile it states a return value of 1, not succeed or anything
11:43.25 d_rossberg DaRock: but does the libtermlib.so in BSD come with the development (aka header) files?
11:44.08 DaRock any chance you could quickly tell me the header file for it? :)
11:44.30 d_rossberg to enable the termlib which comes with brl-cad you have to set BRLCAD_TERMLIB to BOUNDLED
11:44.36 *** join/#brlcad elpea (~chatzilla@dsl-hkibrasgw5-58c04d-211.dhcp.inet.fi)
11:44.57 DaRock not the aim atm
11:44.57 d_rossberg sorry BUNDLED
11:45.43 d_rossberg is the termlib in the base system or a package?
11:45.56 DaRock I have term.h, termios.h, termcap.h, ncurses.h, curses.h, ....
11:46.01 DaRock base
11:48.01 DaRock but if it has the lib, it usually has the header - just not sure which that is right now
11:48.26 DaRock and ncurses-curses are the same here
11:49.58 DaRock d_rossberg: I'll also point out that building tests works fine for termlib according to the logs and my own compilation btw
11:50.14 DaRock so the headers must be found
11:50.47 d_rossberg is just looking in the BRL-CAD sources for a termlib header, couldn't fine one yet
11:50.58 DaRock lol
11:51.09 DaRock what do you know of cmake, then?
11:55.14 d_rossberg it looks like you need termcap.h
11:55.50 DaRock can you see if there's any reference to user set variables having any effect here? ie I should be able to set TERMLIB_LIBRARY or TERMLIB_INCLUDE_DIR and it should honor those
11:55.59 DaRock sorry - file is misc/CMake/FindTERMLIB.cmake
11:58.33 DaRock it also doesn't appear to set any variables (particularly those 2 mentioned) once found - so when it runs that final check... failure
11:59.30 DaRock no include is set, so it may as well play pong for a bit, then continue with the builtin anyway

12:05.00 ``Erik hm, yeah, it's using bundled on one of my bsd boxen, :/
12:05.36 DaRock probably all. same port after all - same here :)
12:05.55 DaRock this all began from a png fault...
12:06.16 DaRock then a conflict with tk/tcl
12:07.19 DaRock the bandaid fix is to allow all bundled... but that just increases dist size, increased chance of conflicts (ie tk)
12:08.11 DaRock apparently its simply going to fail unless you use bundled - which is ok for average user who wants it to work out the box, but if you're a porter or packager...
12:09.35 DaRock ``Erik: btw - urt is not a dependency afaict. There is no need to deprecate the port because urt is builtin - and in fact probably been ignoring the dependent port anyway :)
12:10.45 DaRock but that gets us back to this builtin issue - we should be able to choose system if wanted and add builtins only if needed (like urt)
12:12.27 DaRock ``Erik: can you run a test for me? Comment out the urt under LIB_DEPENDS and see if it builds - you might be quicker on the resolve there
12:12.40 DaRock and runs, mind
12:19.39 DaRock so does anyone know enough about the cmake system to see what needs to change? Honoring overrides, whether the variables are properly set, etc?
12:23.36 d_rossberg i'm using the cmake-gui, there i see all the parameters and can play with them (e.g. trying to set TERMLIB_INCLUDE_DIR to /usr/include)
12:25.07 DaRock does that let you see them during build? Or only prior?
12:26.03 DaRock I don't see anywhere in FindTERMLIB.cmake where that variable is set
12:26.26 d_rossberg before and after the cmake run, the log messages of the runs are shown in the gui too
12:26.30 DaRock I see it says it can be set, but doesn't check it or set it itself
12:26.46 DaRock sounds useful :)
12:27.03 d_rossberg FIND_PACKAGE_HANDLE_STANDARD_ARGS() should set TERMLIB_INCLUDE_DIR
12:27.41 DaRock How? I thought it only checked it was valid?
12:28.00 DaRock afaict thats the fail point
12:28.15 DaRock it isn't set, so that macro fails
12:29.24 DaRock or have I misread the docs on that one?
12:30.09 DaRock that macro fails, then the build fallsback to builtin termlib
12:30.26 DaRock I'm installing cmake-gui now :)
12:32.24 d_rossberg is just checking the FIND_PACKAGE_HANDLE_STANDARD_ARGS()
12:37.24 DaRock I'm a newb at cmake, so tell me if I'm wrong. I read the logic as include some macros, create a new macro that checks header files for a func and validates the include dir and sets the link opts, then runs a series of checks of different terminal/cursor libraries for tputs. (does absolutely nothing with this info) It then starts to setup a test env, and backs up the required libs variable, then sets it to the termlib_Library
12:38.07 DaRock runs a quick compile test, and grabs the result
12:38.20 DaRock can't figure out the mark_as_advanced yet
12:39.15 DaRock then runs Find_Package_Handle_Standard_Args which determines if the library exists, and if the include dir exists
12:42.29 DaRock d_rossberg: so how does cmake-gui work then?
12:45.12 d_rossberg just call cmake-gui, set the build directory there (the souce directory should be automatically set then), and hit configure
12:54.30 d_rossberg as far as i can see the THIRD_PARTY macro (defined in misc/CMake/ThirdParty.cmake) in src/other/CMakeLists.txt line 211 should find and set the TERMLIB_INCLUDE_DIR
13:03.48 *** join/#brlcad kintel (~kintel@unaffiliated/kintel)
13:12.57 d_rossberg DaRock: the bug seams to be in THIRD_PARTY() it doesnt set the _INCLUDE_DIR for system libraries at all
13:13.56 DaRock actually yeah, now that you mention it I didn't see anything either. I'm still trying to process it myself
13:14.49 DaRock That's one bug. I'm wondering if the FORCE is making it only use termlib as well.
13:15.46 DaRock but shouldn't that be something that can be overridden anyway?
13:16.03 DaRock so why not honor it?
13:17.17 DaRock or is it only ever going to do things automatically?
13:23.22 DaRock so would I be right in saying that set(TERMLIB_INCLUDE_DIR "/usr/include") should be used after/in the if(BRLCAD_TERMLIB_BUILD) statement?
13:23.36 d_rossberg the FORCE shouldn't be the problem
13:24.03 d_rossberg TERMLIB_INCLUDE_DIR should be an empty string, i.e. no special directory
13:24.14 DaRock why?
13:24.17 d_rossberg if that's valid ...
13:24.51 d_rossberg /usr/include will always be recognized
13:24.56 DaRock actually, that is practically forcing the use of termcap - why bother checking ncurses then?
13:25.09 DaRock not atm...
13:25.25 DaRock and that's why I'm having trouble I think
13:26.31 DaRock there is no honoring cli input or env vars - its not even checking. The it simply sets its own - /and/ fails
13:27.02 DaRock finally falling back to the bundled for no good reason
13:28.22 DaRock is there anyway to test the FIND_PACKAGE_HANDLE_STANDARD_ARGS separately?
13:32.46 d_rossberg THIRD_PARTY() is the one which should be fixed, i think; just looking at it
13:33.20 DaRock ok, just ran the build with an adjustment to FIND_PACKAGE_.... blah blah (tired of typing that out :) ) by using an empty string instead of the include dirs and it succeeded
13:36.57 DaRock it fails on /usr/include. Weird...
13:39.23 DaRock d_rossberg: so how do we fix it then? use a set()? Check for user set variables?
13:39.31 *** join/#brlcad yorik (~yorik@2804:431:f721:afd0:290:f5ff:fedc:3bb2)
13:44.26 d_rossberg as i've said: i'm just looking at it ;)
13:45.33 DaRock why all the redundant checks btw? It looks like it checks basically the same thing at least 3 ways...
13:47.12 DaRock LOL! I just checked and unless you have an empty string as the last arg it will always fail!
13:49.34 DaRock and again, why is that check needed anyway? It only checks if the include dir exists, and that has already been checked at least twice before!
13:56.02 DaRock fwiw I think FORCE shouldn't be in the set() there already
13:57.12 DaRock and if the test always fails anyway, I'm not sure TERMLIB_INCLUDE_DIR should even be set
14:04.00 d_rossberg lol indeed, the macro in FindTERMLIB.cmake is called from THIRD_PARTY() before it's able to set TERMLIB_INCLUDE_DIR to any meaningful value
14:05.17 d_rossberg FORCE and CACHE together in a set command are depricated, that's true, but not forbidden
14:07.12 d_rossberg however, there are mor obvious issues here than the FORCE (which prevents you from hacking it)
14:11.48 DaRock FORCE overrides any user set vars, right?
14:12.48 DaRock for starters TERMLIB_INCLUDE_DIR is never set AFAICT
14:13.08 DaRock secondly, any value in the last arg will cause a failure
14:13.22 DaRock and why is it needed at all anyway? :)
14:13.52 DaRock other than that, whats the more obvious issues? lol
14:32.01 d_rossberg DaRock: include the line "find_path(TERMLIB_INCLUDE_DIR NAMES termcap.h PATH_SUFFIXES include)" somewhere in FindTERMLIB.cmake before the FIND_PACKAGE_HANDLE_STANDARD_ARGS() and test it again
14:34.15 d_rossberg using the standard FindZLIB.cmake as reference it looks like it is in the responsibility of the find macro to set the include directory
14:34.47 DaRock theres a find_path(TERMLIB_INCLUDE_DIR ${lname}.h) in the macro found there already. I didn't realise that set anything though
14:35.34 DaRock but that of course doesn't include the PATH_SUFFIXES include
14:37.55 DaRock should I simply change the current find_path line?
14:38.42 d_rossberg ? where did you found the find_path?
14:39.03 DaRock in FindTERMLIB.cmake
14:39.15 DaRock around 41
14:44.35 d_rossberg and which revision? i can't find it here: https://sourceforge.net/p/brlcad/code/HEAD/tree/brlcad/trunk/misc/CMake/FindTERMLIB.cmake
14:44.35 gcibot_ [ BRL-CAD / Code / [r69674] /brlcad/trunk/misc/CMake/FindTERMLIB.cmake ]
14:45.55 d_rossberg however, find_path(TERMLIB_INCLUDE_DIR termcap.h) could be sufficient as well
14:48.18 d_rossberg in 2013 the find_path() was removed
14:48.38 DaRock lname should be the library name shouldn't it? and so expand?
14:49.16 DaRock where do I find the rev?
14:49.59 d_rossberg the point here is that the header file's name isn't termlib.h but termcap.h
14:50.24 d_rossberg do you work with subversion?
14:50.30 DaRock nope
14:51.48 d_rossberg but?
14:51.50 DaRock I'd say the point is that FindTERMLIB goes through a series of checks to find a working solution, but only uses the first one - termlib. Why the checks? Why override any user input?
14:52.38 DaRock I'm using the ports system on FreeBSD, so I believe it grabs the releases
14:52.46 DaRock I'll run a check though...
14:53.47 DaRock all I have is 7.24.0 in the Makefile in the ports tree
14:54.07 d_rossberg ncurses etc. are possible replacements for termlib?
14:54.26 DaRock according to FindTERMLIB.cmake
14:56.10 d_rossberg so,
14:56.12 DaRock it runs through a series of checks - and takes the first working one afaict
14:56.38 d_rossberg FindTERMLIB.cmake looks for possible replacements of termlib as well
14:57.31 DaRock I'm not 100% sure of its effectiveness though
14:58.10 DaRock but none of that fixes the final issue of the Find_Package_.... last arg failure
14:59.42 d_rossberg some find_path() is definitely missing, it must set TERMLIB_INCLUDE_DIR too
15:01.06 DaRock well if find_path() sets the TERMLIB_INCLUDE_DIR then its is doing that
15:01.21 d_rossberg i.e. in the 7.24.0 sources you could try to replace find_path(TERMLIB_INCLUDE_DIR ${lname}.h) by find_path(TERMLIB_INCLUDE_DIR termcap.h)
15:02.43 DaRock I don't believe that is the main issue though - the last line (macro) fails because any string aside from an empty one causes it to spit out missing include
15:04.00 DaRock I thought that if TERMLIB_INCLUDE_DIR wasn't set it would cause the fail as well, but if it is actually setting it, then it will definitely go boom - tested that already
15:05.05 DaRock I've set it to "", "/usr/include", "/usr/local/include" and it failed on the final 2
15:05.11 DaRock "" worked
15:05.41 DaRock removing the last arg entirely fixes it too
15:10.11 DaRock so FIND_PACKAGE_HANDLE_STANDARD_ARGS(TERMLIB DEFAULT_MSG TERMLIB_LIBRARY) works
15:10.35 DaRock line 79
15:13.43 d_rossberg really? i tried it and the compile (make) failed
15:14.01 d_rossberg maybe it works with the 7.24.0
15:14.38 DaRock not sure about the compile, but the macro doesn't come back with a failure at least. Compilation is another issue
15:14.46 d_rossberg however, FindTERMLIB is reposible for setting TERMLIB_INCLUDE_DIR
15:17.04 DaRock yes but that macro is in FindTERMLIB
15:17.32 DaRock and regardless of whether that variable is set it will fail
15:17.44 DaRock unless it is an empty string
15:22.18 DaRock alright - this getting very confusing....
15:23.04 DaRock I'm going through sources of output - CMakeError.log, CMakeOutput.log, and stdout
15:23.16 DaRock They all disagree
15:24.31 DaRock CMakeOutput.log says STATUS: Performing Test LIBTERM_RESULT

16:59.38 d_rossberg what is missing in the 7.24.0 is mainly the test if the find_path() was successful

17:04.37 d_rossberg whith a similat statement in the 7.24.0 version of the file it should work too
17:06.19 DaRock ok, I see that. But why was the last macro failing with the TERMLIB_INCLUDE_DIR then? and why did it fail with manually setting it?
17:08.31 DaRock and what happens with the RESOLVE_LIBRARIES() and LINKOPTS?
17:09.20 Notify 03BRL-CAD:d_rossberg * 69676 brlcad/trunk/misc/CMake/FindTERMLIB.cmake: the macro was unable to detect a system termlib because of not setting TERMLIB_INCLUDE_DIR which causes FIND_PACKAGE_HANDLE_STANDARD_ARGS() to fail (and maybe something more)the necessary find_path() was removed in 2013 => integrated find_path() again
17:09.23 d_rossberg manually: because of the FORCE (all variables are FORCED initialized with invalid values)
17:10.12 d_rossberg and the macro was failing because it found the libtremlib.so but not the termlib.h header file
17:10.54 d_rossberg but this generally ok because libtermlib.so is only a symbolic link
17:11.28 d_rossberg the macro finds the real library later on
17:11.47 d_rossberg which is ncurses in FreeBSD
17:12.29 d_rossberg RESOLVE_LIBRARIES() and LINKOPTS seem to be not necessary (any more?)
17:12.31 DaRock SOB!
17:12.45 DaRock I should have picked that up!
17:13.40 d_rossberg i don't think this was a trivial issue
17:13.48 DaRock there are some links all over though - usually between .so and .a files though, so it slipped through... damn! I should have got that though - sorry about that
17:14.57 DaRock righto... I might have a crack on those later then - try remove and see if it doesn't like it. Should work later too if it works on 7.24.0
17:15.20 d_rossberg libtermcap.so is a link too but there is a termcap.h header file - which has ncurses maros
17:15.47 DaRock thanks for the help through it - I'll post back my results later once the brain's/body's had a chance to recover
17:16.07 d_rossberg it was a bug in BRL-CAD nevertheless
17:16.29 DaRock it does make it confusing - there probably should be a link to the header for libtermlib as well
17:16.43 DaRock in BSD that is
17:18.02 DaRock if there's one for termcap it makes sense

05:21.30 DaRock starseeker: thats alright - we're not quite done yet, as we have yet to test here. Speaking of which it hasn't resolved it. It is also an only automated option, so nothing I put in is even recognised, just completely overridden. I'm also concerned with the triple checking - I can't understand the reasoning on it... but thats me :)
05:21.46 DaRock d_rossberg: that didn't work either I'm afraid
05:23.44 DaRock I can link for termlib.h, but I think that misses the point of the exercise
05:24.15 DaRock or is it just a head fix? heh :)
05:24.24 DaRock couldn't help myself there ;)
05:26.00 DaRock if it is just a case of not following dev branch then maybe a link might fix it so we can move on, but that still doesn't allow for any user overrides (for say advanced users or porters)
05:28.29 DaRock I also can't seem to get my head around Find_Package_Handle_Standard_Args(), why it is needed, and why the last arg is such an issue - I don't get the returns from it (I believe strongly that the failure is right there myself). What is expected there?

07:10.54 DaRock ok. It works with the termlib.h link, but that implies that it will work with absolutely nothing else - I have curses, ncurses, and termcap, and apparently none of those will do the trick. They are also linked to the same header file curses.h, so why they fail... So it would appear that there is still another breakage in the cmake system
07:11.51 DaRock but while I'm here :) anyone know what the big issue is here: /usr/local/include/tk8.6/tk.h:21:3: error: Tk 8.6 must be compiled with tcl.h from Tcl 8.6 or better
07:12.34 DaRock I have no other tk version installed, and tcl.h has all the right notes in it, so what the hell?
07:12.59 DaRock and its looking in the right place - not the builtin
07:13.32 DaRock there is bugger all on google for it
07:16.31 *** join/#brlcad teepee (~teepee@unaffiliated/teepee)
07:25.45 DaRock I have a suspicion that it is somehow referencing the builtin tcl.h file when include is called from the tk.h file which is actually included correctly from the system
07:26.47 DaRock it'd be at cross purposes, and this occurs regardless of the use of all builtins as well - tried that earlier
07:27.37 DaRock my system tk.h and tcl.h both have version 8.6 in them. The builtin has 8.5
07:38.23 DaRock looking at the cmake system again seems to make absolutely no allowances for overrides or any intervention by the user - it even seems to ignore the initial assessment of whether the system libraries are suitable
07:39.25 DaRock but if the include variables are set earlier, then it insists on using the builtins, it looks as though this may cause the conflict
07:41.57 DaRock so the automated system (allow_all or not) detects the system libraries and sets them up, the cmake subsystem then tries to ignore all that which means the compiler isn't sure which to header to use from where - regardless of whether the builtins are auto or on or not

02:39.06 starseeker brlcad: could we consider a version reporting mechanism that, rather than compiling in the number of configure runs, pulls it from a file in the data dir somewhere?
02:39.38 starseeker really isn't digging having to rebuild so much of the package every time there's a tweak to the config file that bumps that number...
02:41.42 starseeker DaRock: what OS version are you trying to build on?
02:41.55 starseeker might be able to set up a VM and give it a shot
02:44.38 starseeker DaRock: fwiw, we're considering shifting to a simpler build logic that assumes installed 3rd party components and then maintains src/other as a separate "build and install all of this to get everything needed" convenience
02:45.25 starseeker reliable cross platform detection is unfortunately a very hard problem, as your experiences are indicating
02:46.52 starseeker fwiw, the diagrame on pg. 18 (pdf page 26) of this report tries to document the logic behind the design of the ThirdParty macro: http://www.arl.army.mil/arlreports/2013/ARL-TR-6475.pdf
02:46.53 gcibot_ [ Access Denied ]
03:31.24 DaRock starseeker: thats fine, I think the idea is sound, but the code hasn't been tested as thoroughly I don't think; so when I come and turn everything off it goes bang! and we uncover a lot of issues that probably haven't been touched due to inconvenience. eg the common fix is to enable all the builtins.
03:31.51 DaRock if I could get my head around it, I could probably sort some of it, but....
03:34.48 DaRock right now, I think what I'm seeing is that even if the system libs are discovered and sorted - and set to be used - the cmake system still turns around and insists on using the builtin. i'm trying to figure out what would be needed to make this an if/else logic, where if the system libs are set, then use those, but only set the local(?) includes on if not. Right now it says in the comments to guarantee the builtins come first - no matter what
03:38.08 DaRock the detection stuff I've seen appears to be sound - its the natural insistence on the builtins which means a lot of this ends up being wasted/ignored. Its not just "falling back" as advertised, its ignoring the system mostly
03:38.45 DaRock maybe I'm just focused on a few modules though :)
06:08.08 DaRock Ok, I have it figured - just need to work on a fix. The forced use of the builtin tcl uses the builtin header tcl.h. But that does not force the use of the builtin tk header. So the current tk/tcl is 8.6, and so the tk.h is newer than the builtin, which then errors because the builtin tcl header is set for 8.5.9, hence the cross pollination...
06:09.33 DaRock the file is src/libtclcad/CMakeLists.txt

17:37.14 starseeker DaRock: that FindTCL.cmake module we have is a bit of a nightmare - it's one of the oldest pieces of CMake logic in the code, and it was written early in the conversion process from automake
17:37.24 starseeker i.e. before I knew what I was doing
17:38.12 starseeker we're also attempting to store and reset the CMake variables when we add src/other/CMakeLists.txt
17:38.24 starseeker that could be causing some state management problems
17:39.47 starseeker in the tcltk86 branch I think we ditch our internal FindTCL entirely and rely on CMake's built-in - you might see if doing that helps
17:43.32 starseeker DaRock: good catch figuring out the using tcl.h but not tk.h from built-in, btw - that's indeed a scenario that either hasn't come up much or we "got away with" when the system header ended up as compatible
17:44.54 starseeker if we really wanted to be aggressive about doing the right thing, we would check the libraries pulled in by system versions of libraries to try and catch any conflicts (for example, a system libpng being pulled in and conflicting with an enabled build of png in src/other)
17:45.32 starseeker I don't know of a cross platform way to do that though, so it would likely involved writing a complex new CMake module to wrap it all

10:55.50 DaRock starseeker: KISS. As well as DRY (which is why I can't figure out the test repetition :-) ). I'd say if the build is by user "Average", then they should go with the bundled. If the user is Developer/Porter, then they know what they're doing, and can fix it if it goes wrong, so they should supply the required info so that the cmake system doesn't have to go searching. But the auto is there, so it could muddle through for user Average in theory...
10:56.57 DaRock That would fix the tcl/tk issue particularly :-)
10:57.58 DaRock But the biggest hurdle is finding how to get the variables through from the cli

05:44.38 brlcad it's now back to considering single grazing hits as a hit instead of a miss, so we'll have to be on the lookout for changes we're not testing
05:45.20 brlcad it was a problem earlier because it wasn't reducing out-of-bounds cylinder hits fully, which is what solids caught
05:46.53 brlcad only time it should happen now is if root solver ever returned 1 hit (which I'm not sure it can) or if we somehow perfectly hit an edge such that we hit one surface but numerically miss the other, just outside tolerance

09:56.02 DaRock brlcad: I have a running program now - I'm still learning the system, so I can't specifically say whether I have any run faults yet :)
09:58.40 DaRock brlcad: it began with libpng errors in the normal port on FreeBSD - conflict between the system lib and the builtin lib, it couldn't find the builtin. Also urt port is no longer available, and therefore brlcad port was due for removal soon. Since urt is actually builtin, then building the urt port was pointless.
10:02.09 DaRock brlcad: specifically to your interest, running the build with bundled option off ran into several issues. First, it couldn't find termlib. It looks for other options, finds them as far as can tell, but refuses to use them. FreeBSD uses the ncurses system, but links the headers and libs to show curses, ncurses, and termcap. It even has libs for termlib, but no header; so in looking for termlib, the build found the lib,
10:02.24 DaRock brlcad: but not the header and so failed.
10:05.07 DaRock brlcad: A fix was made to FindTERMLIB.cmake to get it to set the variables properly, but it still had issues as you could see with the header. I ended up just linking the termlib.h due to temporal restrictions
10:10.11 DaRock brlcad: next was tcl/tk. It wouldn't use the system headers at all - the build system specifically states that it wants to guarantee the builtins. Worse, it only did that for tcl - not tk - so of course there would be conflict in versions. That was a wash really - I hacked the CMakeList.txt to libtclcad to check if the system libs are set to be used and use them and specifically ignore the builtin tcl/tk.
10:14.05 DaRock brlcad: I also had to hack it so that it found the tcl/tk include dir, as well as the subfolder as is already done for the builtin - ie tclX.x/generic. I found setting that system wide created issues elsewhere, and could only be specifically set in that cmake file.
10:16.20 DaRock brlcad: ideally this stuff should be possible to set from the cli using an env variable like -DTCL_INCLUDE_DIRS or such, as if you are not going auto or bundled then you must be a dev/porter and know what you are doing and can resolve it if things go wrong. My 2c - save the tcl/tk conundrum at least, anyway... ;)
10:17.05 DaRock support on here has been good to btw, thanks all.... now if only I could find some good tuts on how to use it....

02:41.51 Stragus Hey guys, I don't know if you ever used meshdecimation.c somewhere, but it was in the BRL-CAD tree
02:42.09 brlcad Stragus: yep, it's still there
02:42.14 Stragus Anyway, I did an update with minor API breakage, improved robustness (will handle broken topology) and other goodies
02:42.28 starseeker sweet!
02:43.23 starseeker https://sourceforge.net/p/brlcad/code/HEAD/tree/brlcad/trunk/src/librt/primitives/bot/gct_decimation/
02:43.23 gcibot_ [ BRL-CAD / Code / [r69739] /brlcad/trunk/src/librt/primitives/bot/gct_decimation ]
02:43.33 starseeker our copy is living in there atm
02:43.54 Stragus It now has the features required to be able to decimate meshes with per-triangle data, like materials, with a per-edge "custom weight" callback where materials differ, and so on
02:44.01 Stragus http://www.rayforce.net/meshdecimation.c http://www.rayforce.net/meshdecimation.h
02:44.13 Stragus You would have to check the API though, it has changed
02:44.18 brlcad well, and src/other/gct/MeshDecimation ... but needs to be cleaned up
02:46.40 starseeker Stragus: do you have any standard set of CMake detection tests for the various CPU_ENABLE_SSE style flags?
02:47.06 brlcad notes there were 16 patches made
02:47.12 brlcad er, 61
02:47.36 Stragus CPU_ENABLE_SSE is basically optional to force it. #if __SSE__ || _M_X64 || _M_IX86_FP >= 1 should be pretty reliable
02:47.39 starseeker doesn't know that he ever got the proper tests in there for all the high performance SSE stuff - some of those patches may have been disabling stuff..
02:48.04 starseeker Stragus: ah, so the compiler itself (or rather its internals) should do the job?
02:48.08 Stragus Yes
02:48.21 Stragus Well, it works for GCC, clang, ICC and MSVC. I guess that's enough
02:48.27 starseeker heh :-)
02:49.02 starseeker most likely problem children are probably older gcc verisons
02:50.29 starseeker Stragus: did you ever put together your nanovg/nanogui slaying high performance OpenGL widget set?
02:50.44 starseeker remembers catching it for being interested in fontstash...
02:51.09 Stragus Not really, if you only want font rendering... I could share my Freetype-based font manager
02:51.44 Stragus The GUI itself isn't unfinished and undocumented with a monstrous API, so that's probably not a good idea :)
02:51.52 starseeker heh
02:52.14 starseeker regrettably, our own GUI layers are still primitive enough that it'll probably be a while before we need to worry about it :-(
02:52.44 starseeker we're still using the glx/wgl specific libdm backends
02:52.55 starseeker quietly beats head on desk...
02:54.11 starseeker Stragus: are teh mmatomic, mmhash, etc files still pretty much the same, or have they been updated as well?
02:54.50 Stragus Okay, here's probably everything that matters: http://www.rayforce.net/brlcad/
02:54.50 gcibot_ [ Index of /brlcad ]
02:56.27 Stragus I uploaded fontmanager.* but it's independent of the "renderer" itself, basically a struct with a bunch of function pointers
02:56.39 brlcad Stragus: do you happen to keep that in a repo?
02:57.01 Stragus Sorry, not really, git and I... don't get along
02:57.28 brlcad i recall we ran into a ton of portability issues, and redoing all of them doesn't sound too fun :)
02:57.36 Stragus Agreed
02:57.53 Stragus I probably fixed many of them myself... mmthread.h even compiles on MSVC and uses native windows threads
02:57.59 brlcad looking at the log, looks like about 14,000 lines got edited
02:58.04 Stragus Darn
02:58.10 brlcad but might be a lot of formatting updates, could be misleading
02:58.45 starseeker vaguely remembers the older gccs Redhat and OpenBSD use being issues...
02:58.46 brlcad I do know a few specific things like instead of requiring c++11, it was ported to tinycthread
02:59.06 brlcad and runtime sse detection was added
02:59.25 Stragus Runtime SSE detection should be less an issue these days
03:00.24 Stragus Well, the old meshdecimation had this little "problem" that if the mesh's topology was incorrect/broken, it could crash
03:00.40 starseeker https://access.redhat.com/solutions/19458 - Stragus, how do these gcc versions do?
03:00.43 gcibot_ [ What gcc versions are available in Red Hat Enterprise Linux? - Red Hat Customer Portal ]
03:01.00 starseeker < gcc4 obviously don't count...
03:01.34 Stragus It shouldn't require any modern GCC feature, I know it compiles with 4.9.3
03:01.57 brlcad runtime sse was for deployment, still very much an issue
03:02.18 brlcad you compile on an sse system, but binaries get installed on somebody's machine without support -- crash
03:02.39 Stragus True. But that machine would have to be from 2002 or something
03:02.56 brlcad crash was hit before we even released just 2 years ago iirc
03:03.12 brlcad yeah ... and? :)
03:03.30 starseeker dinosaurs still walk the earth ;-)
03:04.07 Stragus Eh. :)
03:04.10 brlcad it wasn't hard to add runtime detection -- we already had a routine
03:04.17 brlcad just had to hook it in the right places
03:04.20 Stragus Right
03:05.20 brlcad still worth getting this update because crashing on non-solid meshes sucks too
03:05.30 starseeker very much worth doing if we can get additional robustness
03:05.41 brlcad just wondering if there's a way we can get you any repatching for round 3 later? :)
03:05.48 Stragus Non-solid was okay, the problem was two triangles sharing the exact same edge, like AB twice
03:06.06 brlcad or get you commiting directly to repo or something
03:06.23 starseeker will have to hit this with the faa models in brlcad/db/faa
03:06.51 starseeker iirc, they blew up pretty spectacularly earlier (not much solid in the Generic_Twin...)
03:07.00 brlcad decides he can wait and closes the browser window of 70" oled's
03:07.14 starseeker hehehe
03:08.50 starseeker is hoping the Dell 8K monitors come down from $5K in the next few years - that'll probably be the last monitor I ever need to buy
03:09.21 starseeker Stragus: are you not set up to commit to BRL-CAD?
03:09.22 brlcad Stragus: then there may be some other bugs still lurking -- the cases I ran into weren't duplication/sharing
03:09.32 Stragus Oh, and we talked about sorting faster than qsort() a w hile... ccradixsort.h is all inlined and should be pretty good
03:10.13 Stragus starseeker: I don't think so, and I would have difficulties testing my commits without tracing where it's used
03:10.42 Stragus a while* ago
03:10.55 starseeker nods - we could set up some unit testing - I'm thinking this would actually make sense at the libbg level, although brlcad may disagree
03:12.15 starseeker checks where it's currently hooked in...
03:13.19 brlcad all that's needed is to PRE-define what data types go with what libs, then there's not really much room for agreement or disagreement
03:13.40 brlcad it's adding types for convenience that I resist, too many types makes for a bad lib
03:14.03 brlcad overlapping types makes for confusion
03:14.10 brlcad (and overhead)
03:14.16 starseeker nods
03:15.05 starseeker looks like rt_bot_decimate_gct is what's calling into gct right now
03:16.58 starseeker Stragus: I think that may be the only bridge, so our API updating should be confined to that one function
03:17.14 Stragus All right
03:21.29 starseeker Stragus: I'll try to sneak some time to do some experimentation in the next couple days - I don't know if the FAA model decimations will be sensible, but I'm fairly sure they'll be mean ;-)
03:21.46 Stragus What are these models?
03:22.43 starseeker They're from an old FAA study back in 2004: http://www.tc.faa.gov/its/worldpac/techrpt/AR04-16.pdf
03:23.29 starseeker we initially sucked them in for testing our FASTGEN importer, but they've also proven useful for BoT testing
03:23.44 Stragus The models in the PDF seem pretty simple
03:24.27 starseeker reasonably - otherwise we wouldn't want them in the main repo - but they're also not solid
03:24.51 Stragus Well, let me know if something breaks
03:25.21 starseeker nods - will do. They're obviously intended as a "stress test" for invalid inputs, not something that really *needs* decimation
03:25.43 starseeker can always go grab the bigger stanford models for that :-)
03:26.10 starseeker although I imagine you're there ahead of us
03:26.37 Stragus And if you liked that guy's radix sort doing 50% faster (or whatever it was) than std::sort, try the SSE optimized ccradixsort (~500% times faster)
03:26.52 starseeker :-)
03:27.03 starseeker that's pretty cool
03:27.43 starseeker Stragus: thanks for the heads up!
03:28.06 Stragus :) You are welcome
03:29.48 starseeker Stragus: now, how do we get you interested in robust boolean operations on meshes? ;-)
03:30.25 starseeker ducks and runs
03:31.12 Stragus Ah! :) I don't know much about that, it seems tricky
03:31.36 starseeker there've been a number of interesting papers out in the last few years
03:32.03 starseeker http://www.gilbertbernstein.com/resources/booleans2009.pdf for example
03:33.57 Stragus I assume you already have "state of the art robust Boolean operations"? It's just slow?
03:34.02 starseeker nope
03:34.23 starseeker our facetize command is prone to crashing
03:34.57 Stragus That sounds bad
03:35.12 starseeker preferred approach was/is to convert CSG to NURBS brep, do the booleans in brep space, then mesh the final result
03:35.44 starseeker we got some good GSoC work on that, and nreed has done some as well, but there is a ways to go yet to get that really working right
03:35.59 starseeker in the meantime, we're stuck with the old NMG pipeline
03:36.41 Stragus So the actual problem is converting a soup/hierarchy of CSG into triangles?
03:37.12 starseeker well, that's one of them. There are also use cases for the NURBS model, but for shaded displays we've got to get to triangles
03:38.09 Stragus Well, it does sound interesting. I'm so tired of physics. And I think I'm getting good with geometry problems
03:38.21 Stragus The last little thing was a Constrained Delaunay Triangulation that's many times faster than supposed state of the art
03:38.28 starseeker cool!
03:38.45 starseeker we use poly2tri for that currently
03:39.27 Stragus Here's my CDT in action: http://www.rayforce.net/cdttestgood.png in a couple milliseconds
03:39.33 starseeker was kinda hoping to get some GSoC proposals on the geometric guts, but they're tough projects for a summer
03:40.53 starseeker wow
03:41.04 starseeker that's a mean input
03:41.14 Stragus Yup, I was trying to break it :)
03:42.52 Stragus And rendered with SSE optimized perfect antialised rendering... I'm writing weird stuff sometimes
03:43.01 starseeker hehe
03:44.27 starseeker if you really want to fry your brain, look into exact geometric computation: https://hal.inria.fr/inria-00344355/file/p.pdf
03:45.17 starseeker for people who Really Care About Robustness
03:45.31 starseeker *that's* some tough stuff to make fast
03:47.30 Stragus It's always a good idea to design algorithms that consider the numerical accuracy of your floats
03:48.50 starseeker nods - most geometry algorithms can't/don't though - if you have a point and a line in space, and your algorithm cares if the point is to the left or right of the line, you've got trouble
03:49.23 starseeker https://www.mpi-inf.mpg.de/~mehlhorn/ftp/classroomExamplesNonrobustness.pdf
03:49.43 Stragus The idea is generally to have a third scenario, "somehere about on the line", and have some way to manage that and still produce meaningful results
03:49.54 Stragus I had to do that in the triangulation too
03:50.47 starseeker Stragus: you'll probably have a better appreciation for the classroom examples of nonrobustness then :-)
03:52.13 starseeker as I understand it, there are also different "categories" of robustness - once you add repeatability, things like "about on the line" get tricky because you can also get floating point noise interfering with when the call of "close" is made if platforms vary
03:53.56 Stragus The idea is that whenever something is "close", you make it robust, you pick a decision and that's how it stays. "I decree and declare that A is on the LEFT of line B, forever and ever"
03:53.59 starseeker Stragus: someday (in my infinite free time) i'd like to do some experimenting with ECG and other strategies like snap rounding
03:54.25 Stragus That result can be stored in some space partitioning, hash table, or whatever; and you look it up whenever you are within the range of inaccuracy
03:54.50 starseeker neat stuff
03:56.02 starseeker has to call it a night - thanks again Stragus for letting us know about the robustness updates!
03:56.08 Stragus Good night!

09:13.31 pgabor I would like to ask which kind of tasks do you have and of course where to start if I want to participate?
09:15.05 pgabor Some things about me:
09:20.57 pgabor I am Physics MSc student in Hungary at Eötvös Loránd University. I am very interested in computational physics and materials physics. I have experience with, c, c++, python, Qt, javascript, java. My current student scientific research is developing a new efficent simulation tool for edge dislocation dynamics. Till now with great success :)
09:28.25 Stragus Interesting. Stick around a little, most of the team will wake up in 1-3 hours ;)

03:12.08 Stragus bookmarks that just half-way through reading
03:14.01 Stragus can't agree with #17 though
03:16.16 brlcad yeah, I cringed at that one a bit
03:30.53 Stragus I'm unsure how common it is, but I have found invaluable this little trick of being able to turn on some #define and produce very verbose logs on any and all problems or sub-problems
03:31.28 Stragus I pretty much always do it now, even before any bug is found or suspected, just to be able to quickly inspect the internal flow if ever needed
03:40.57 Notify 03BRL-CAD:brlcad * 69867 brlcad/trunk/src/other/tcl/CMakeLists.txt: define the right thing for the AvailabilityMacros.h test
03:42.52 Notify 03BRL-CAD:brlcad * 69868 brlcad/trunk/src/other/tcl/CMakeLists.txt: these have been wrong for some time, define the right symbols
03:44.17 brlcad i do that for standalone and some unit tests, but rarely for production code
03:44.39 brlcad but brl-cad employs that pattern very pervasively for debug logging
03:50.15 Stragus Not for production code? I see
03:50.52 Stragus It's also very useful to validate usage of some API. "I'm doing X and it doesn't work!" ~ I ask the log and I can see everything, including bad input/usage
03:52.29 brlcad good unit tests can be useful for that too, one of the points they make
03:52.46 brlcad they become defacto examples of usage
03:54.05 Stragus Yes well, I still had people try to trace rays with vectors of NaNs, triangulate overlapping vertices, smooth lines with an interval of zero
03:54.58 brlcad good unit tests always check boundary conditions including nan and inf ;)
03:55.55 Stragus I would argue that there are valid performance reasons to intentionally break/fail on non-sense input :)
03:58.00 brlcad fast is useless if it doesn't handle their data, and geometry data is pervasively dirty, invalid, non-sense
03:58.47 brlcad in my experience, it's above 90% of production models have at least some invalid geometry
03:58.50 Stragus Yes, I have realized that recently once again... OpenStreetMaps data is full of non-sense. Contours that overlap themselves, you name it
03:59.45 brlcad academic data sets are about the only thing I run into that tends to be clean
03:59.55 brlcad unless it's an academic data set about unclean data ;)
04:01.10 Stragus I'm actually annoyed by designing clever, robust algorithms that work perfectly with good input, including handling of limited floating point precision. Then people feed it bad input and complain
04:01.22 Stragus But that's just what the data is

19:38.25 vasc pokes at mdtwenty[m]
19:50.44 vasc there was a site with IRC logs for this channel somewhere. someone got a link to the logs?
20:07.18 mdtwenty[m] Hey.. After our conversation last week, i came up with a new solution to the weave_segs kernel. I tried first to implement it without allocating a fixed size array to store the segments in each partition, and although the number of partitions per ray was correct, the segments in each partition were not and the code was a bit messy. So I decided to first implement it with a fixed array of segments in each partition (I
20:07.18 mdtwenty[m] started with an array of 100 elements because it was sufficient for the example) and the results seemed ok (i.e the number of partitions and segments in each partition after boolean evaluation seemed correct for the example i am using to test)
20:11.25 vasc i don't see how that makes things simpler since it was bounded... but do continue.
20:12.09 vasc mdtwenty[m]
20:13.58 starseeker Notify: irc
20:14.03 starseeker hmm
20:14.42 starseeker don't remember how that works
20:15.20 starseeker vasc: I think you're looking for this? http://infobot.rikers.org/%23brlcad/
20:15.25 gcibot_ [ apt/ibot/infobot/purl logs for 2017 ]
20:15.30 vasc yes. that's it! thanks!
20:18.10 mdtwenty[m] I tried to make it bounded first so it would be easier to compare the results with a new solution, but if we were to alloc the array with the total number of segments, how we could do that? Since we only know that number after the count_hits kernel is executed
20:19.26 vasc yeah but why would you need to know the size before calling count_hits anyway?
20:19.59 mdtwenty[m] and when i tried to alloc the memory for that array before creating the opencl bufer, it would take to much time to execute comparing with the previous solution
20:20.23 vasc eh?
20:21.05 vasc in theory you'll only need to allocate buffers in the graphics card memory.
20:22.02 vasc opencl buffers.
20:22.52 vasc i don't see how allocating a smaller buffer will be slower than allocating a larger buffer. which is what will happen if you have 100 segments per pixel.
20:27.27 vasc you're talking about this?

20:27.38 vasc h[i] = h[i-1] + counts[i-1]/2;/* number of segs is half the number of hits */
20:27.40 vasc <PROTECTED>
20:27.42 vasc <PROTECTED>
20:27.45 vasc that code is only there because we don't have opencl prefix sums implemented
20:27.51 Stragus When the buffer runs out, you can return failure, realloc, then just try again with a bigger buffer and/or fewer rays?
20:27.53 vasc it should be done all in the opencl side eventually.
20:28.04 vasc you won't need to realloc
20:28.11 vasc man
20:28.55 vasc IIRC the max amount of partitions is 2x the amount of segments right?
20:29.07 vasc so you just allocate that as the maximum buffer size.
20:29.36 vasc and then you dynamically grow the virtual buffer, sure, but it will never go past the maximum buffer size.
20:31.06 Stragus I seriously lack context here, but the maximum buffer size for buffering all hits through a complex scene can be astronomical. It's very practical to "return failure and try again", it almost never happens in practice
20:31.21 vasc no it's not.
20:32.00 Stragus Counting hits first also isn't relible since optimization of different kernels will produce slightly different results... besides the whole problem of tracing rays twice
20:32.24 vasc allocating memory is much slower than counting hits.
20:32.40 Stragus You allocate once and reuse the same buffer over and over
20:32.46 vasc hm
20:32.57 vasc sure that would work.
20:33.04 vasc but why bother.
20:33.12 Stragus It's the most efficient solution?
20:33.22 Stragus has done exactly that in another ray tracer...
20:33.24 vasc i would be happy with something that actually works first.
20:33.41 Stragus Counting hits isn't reliable
20:33.49 vasc why isn't it reliable?
20:34.25 Stragus Because the kernel to count hits and the kernel to record hits are different. They use the same function, but they will all be inlined by the compiler and optimized in different rays
20:34.29 Stragus Err, different ways*
20:35.02 vasc so you're saying the opencl device won't produce the same results if you run the same code twice? that it isn't deterministic?
20:35.21 Stragus It's not the same code, it's two different kernels: counting hints and recording hits
20:35.33 Stragus Unless you actually have one kernel that does both with a branch. Less efficient though
20:35.47 vasc it's the exact same code. except one stores the results and the other one doesn't.
20:36.27 Stragus You do realize that everything OpenCL/CUDA is preferably inlined in the calling device function as one big fat function?
20:36.41 Stragus And when you inline and optimize floating point math, results differ slightly
20:36.50 vasc i don't see how that makes any difference in the code results. unless the compiler has a bug.
20:36.56 Stragus (a+b)+c != a+(b+c)
20:37.05 vasc especially because they both call the same exact functions.
20:37.21 vasc man, i have it running and it works(tm)
20:37.37 vasc i count the hits, alloc a buffer for the hits, and then store them
20:37.40 vasc it's in SVN
20:37.42 Stragus Okay, but it's not reliable if you enable optimization
20:37.50 vasc why shouldn't it be?
20:38.24 Stragus _If_ you use two separate kernels, it's all inlined and optimized separately, with slightly different results
20:38.33 Stragus If you use a branch in the same kernel, it's fine, but slower
20:38.37 vasc no man. because it's THE SAME KERNEL
20:38.49 vasc they only difference is a branch which either stores the result or not.
20:39.12 vasc :-)
20:39.33 Stragus Okay, and you end up tracing rays twice
20:40.10 vasc sure.
20:40.17 vasc which still beats re-allocating memory.
20:40.25 Stragus You don't reallocate!
20:40.49 vasc sure. then you replace this simple to solve problem with a more complex problem.
20:40.50 Stragus When I did something similar/identical, I had a batch of 32 buffers to store results (one buffer per thread/lane), the offsets were incremented by atomics, and there was a special flag to denote "I ran out of memory"
20:41.02 vasc so which size of buffer will you allocate that can use all the gpu compute units?
20:41.24 vasc my solution doesn't require atomics either.
20:41.26 Stragus If that flag was ever set, you would reallocate _or_ trace less rays. And you did that maybe once, if the heuristics were off for the scene's complexity
20:41.29 vasc its lockless.
20:42.11 Stragus Wait actually, it wasn't one buffer per thread/lane, I was doing one atomic for the whole warp after counting how much memory all of it required
20:42.21 Stragus The hits being buffered in on-chip shared memory
20:42.55 vasc atomics don't work on shared memory. they work on global memory.
20:43.00 vasc at least in opencl it's like that.
20:43.34 vasc plus if you're doing inter-warp computation you don't need atomics.
20:43.59 Stragus You have both in CUDA... but the atomics were for the global buffer, shared memory was only for accumulating many hits before flushing to global (with one atomic operation to allocate and flush the results of all threads of the warp)
20:44.06 vasc ah ok.
20:44.22 vasc you're still replacing a simple problem with a more complex problem.
20:44.38 Stragus It's a little complex, but it's much faster than tracing twice
20:45.08 vasc meh. there's way worse inneficiencies in the code right now.
20:45.26 Stragus Okay then. :) Perhaps keep all this in mind for a future iteration
20:45.37 vasc sure.
20:47.39 vasc anyway mdtwenty[m], the problem with the change you made is that you can't assume that buffer will be large enough to hold the results.
20:48.17 mdtwenty[m] yes i'm aware
20:49.00 mdtwenty[m] and perharps i did something wrong when i tried to allocate the buffer for the array of segments in each partition
20:49.25 vasc at one point we actually computed that prefix sum with opencl and did no memory transfers in that code, but the thing is i was using a prefix sum code with an Apache Public License code so it needed to be ripped out.
20:49.54 vasc will need to either get an MIT licensed algorithm or reimplement it eventually.
20:50.07 vasc but for now it doesn't matter.
20:50.15 vasc well
20:50.23 vasc i wouldn't be surprised if there was a bug there.
20:50.53 vasc its okay to try things with a simpler piece of code for now, but eventually you need something that works properly.
20:51.58 mdtwenty[m] yes the idea of implementing first this simpler code was to have a base to compare the results with future solutions
20:52.44 vasc you could just make a mockup that returns white when there are intersections and black when there are none.
20:52.52 vasc so it would make debugging your results easier.
20:53.47 vasc i.e. a replacement for clt_shade_segs_kernel
20:54.34 mdtwenty[m] yes thanks i will do that
20:55.46 vasc eventually you'll need to get the material right as well.
20:56.20 vasc where was that in the ANSI C code...
21:03.42 vasc right
21:03.58 vasc https://svn.code.sf.net/p/brlcad/code/brlcad/trunk/src/rt/view.c
21:04.00 vasc colorview()
21:05.32 vasc the opencl rt is basically a mix of ANSI C librt, liboptical and rt code...
21:05.46 vasc with a lot of things deleted.
21:06.11 vasc to make it something a human being can understand.
21:06.45 vasc of course most of those features will probably need to be added back eventually.
21:14.01 mdtwenty[m] sure :)
21:14.55 mdtwenty[m] i will implement your suggestion of shading the intersections with a different color to see it there is still a problem with the weave_segs kernel
21:15.37 mdtwenty[m] and will also work on replacing the bounded array
21:19.09 vasc just make sure to keep backups
21:19.43 vasc once you get a black/white shader working then message me.
21:23.17 vasc i also started with before i got the shading working properly:
21:23.19 vasc https://brlcad.org/w/images/thumb/8/87/Cl_havoc.png/512px-Cl_havoc.png
21:25.04 vasc s/started with/started with the black&white shader
21:25.23 mdtwenty[m] yes it is definitely a good idea
21:26.07 mdtwenty[m] i will implement that and will give you a heads up when its done :)
21:38.02 vasc okay then
21:38.32 vasc i notice you've been updating your blog, so keep at it
21:43.38 mdtwenty[m] yes i will keep posting my daily progress on the blog!

Probably should figure out how to recognize when we're converting parts

14:08.55 gabbar1947 Actually I did not make any changes to the file, Its somehow reflected in the patch.
14:09.01 gabbar1947 I'll check once
14:10.12 gabbar1947 I'm unaware of any such change made by me, I have no idea why this reflects in the patch
14:12.21 d_rossberg i'm recommending looking at a patch file with a text editor and to check if it looks reasonable
14:13.18 gabbar1947 I'll revert the change to the CmakeList.txt, Is there anything else that you want me to look into ?
14:13.36 d_rossberg in addition you have trailing spaces in your code
14:14.13 d_rossberg the "good" text editors provide a function to remove them all in one step
14:14.58 gabbar1947 I tried to remove as much as I could, anyways I'll go through the files once again. I'll use a text editor other than vim.
14:16.41 d_rossberg google says in vi it is :%s/\s\+$//e
14:18.22 d_rossberg see https://vi.stackexchange.com/questions/454/whats-the-simplest-way-to-strip-trailing-whitespace-from-all-lines-in-a-file/

14:18.35 d_rossberg and its reference to vim.wikia
14:18.43 gabbar1947 works! thank you
14:19.45 gabbar1947 On it! just a moment
14:22.20 d_rossberg i wrote my documents with vi for many years, you can write great literature with it - if you are tough enough for it
14:29.50 gabbar1947 can you give it a try now, and let me know if there are more errors !
14:34.33 d_rossberg ok: typein.c has trailing spaces and a C++ comment (i.e. //)
14:35.41 d_rossberg maybe you should simply remove the line - and the number of segments in p_annot for the sake of simplicity (see seans mail)
14:35.52 gabbar1947 I'll remove it ! The C++ instinct !
14:38.01 gabbar1947 Actually I wanted the "l" command to display the annotation container details as well, that was the reason for its inclusion. anyways i'm removing it!
14:38.13 d_rossberg run the :%s/\s\+$//e on all files you've touched to make sure that no trailing space left
14:38.38 d_rossberg isn't typein.c the in command?
14:42.31 d_rossberg sorry, i had an old patch, in the actual one all trailing spaces seem to be gone
14:42.40 gabbar1947 :)
14:43.41 gabbar1947 typein.c is the "in" command! but for the describe() function for annotation displays the container params as well, so just wanted to see the details on the screen, that's it !
14:44.22 d_rossberg ok, it's on your decision
14:46.58 gabbar1947 I'm submitting the patch, once build completes !

15:50.01 vasc hey
15:50.04 vasc hello mdtwenty[m]
15:50.23 mdtwenty[m] Hi :)
15:51.02 vasc so... you said something about only supporting one partition?
15:52.03 mdtwenty[m] not only one partition.. one region
15:52.09 vasc right.
15:52.52 vasc but that isn't in the weaving part proper right?
15:52.58 vasc it's in the evaluation for rendering?
15:53.37 mdtwenty[m] yes it in the evaluation part
15:53.51 vasc well. you haven't implemented rt_boolfinal yet.
15:54.35 vasc is there anything left to do in the boolean weaving?
15:55.36 mdtwenty[m] i don't think so.. i think the boolean weaving is already fine
15:56.10 mdtwenty[m] i was looking now into the rt_boolfinal
15:58.02 mdtwenty[m] *i also uploaded today the weave patch without using the pointers in the cl_partition structure
15:58.38 vasc yes. i've seen that. i'll have to review it more in depth later but it seems fine on a cursory glance.
15:59.28 vasc there's still the question of linked lists vs arrays, but without more complex test scenes there's no good way to benchmark it.
16:02.15 vasc the most complex test scenes on the standard database files are probably goliath and havoc. but i'm not sure if they use much csg
16:02.35 vasc they probably don't.
16:03.07 vasc have you tried rendering those to see what happens?
16:03.15 vasc and the operators scene.
16:03.22 vasc oh right. rendering issues.
16:03.34 vasc well.
16:03.38 mdtwenty[m] the havoc and the goliath?
16:03.47 vasc yes. havoc.g and goliath.g i think
16:03.53 vasc in share/db or something.
16:04.05 mdtwenty[m] yes i see it
16:04.08 mdtwenty[m] one sec
16:04.38 vasc if it doesn't crash that would be good enough i guess.
16:04.43 vasc for now.
16:05.27 vasc hopefully it's not horrendously slow either.
16:06.23 mdtwenty[m] hm the goliath scene fails the assertion of 32 segments per ray
16:06.30 mdtwenty[m] so i think 32 is not enough
16:06.30 vasc hah.
16:06.50 vasc see what's the max depth.
16:07.41 vasc it's still prolly under 64,.
16:08.24 vasc i think i have some dynamic bitvector code in opencl or ANSI C in here somewhere you could use if it's bigger than that.
16:11.35 mdtwenty[m] is there a function to see what is the max depth or something?
16:12.22 vasc no. just in that for loop where you do the assert, keep track of the max segments per ray size, and then print it out when the loop ends.
16:13.18 vasc there might be something like that in one of the brlcad tools, but i'm not sure if it would work with the opencl backend.
16:20.00 vasc ok found it

16:20.31 vasc -
16:20.33 vasc this is my code, so i give you permission to it for any purpose.
16:20.49 vasc where WORD_BITS is 32 since 'D' is an array of cl_uints
16:21.33 vasc and N is the amount of bits you want the bitvector to have.
16:21.42 mdtwenty[m] i got maxdepth of 957571
16:21.48 vasc WHAT
16:21.52 vasc do the math properly dude.
16:21.58 vasc :-)
16:22.02 vasc that can't be truel.
16:22.13 vasc max per segment, not the sum of everything.
16:22.55 Stragus Still not a fan of allocating chunks out of big buffers through atomics, eh :)
16:23.27 vasc we might do that eventually. but for now there's a lot of gfx card memory we don't use.
16:24.01 Stragus All right. It goes up quickly when buffering all hits for millions of rays
16:24.52 vasc well sure. we could find the warp size and only allocate a buffer of that size or something.
16:24.57 vasc it's too much work :-)
16:25.27 vasc those microoptimizations can be done later.
16:25.59 vasc i kinda doubt we need to do it this way anyway.
16:26.12 vasc i suspect we could do the csg processing in an iterative fashion with a modified algorithm.
16:26.48 Stragus So you want to allocate the "max depth" for every ray... and how do you determine that max depth?
16:27.22 vasc we count the amount of segments per before allocating and actually storing the segments.
16:27.33 vasc we count the amount of segments per ray before allocating and actually storing the segments.
16:27.37 Stragus Ideally, you would process the segments as they come rather than buffering the whole thing. That complicates the code though
16:27.51 Stragus Ah yes, the two passes thing, count then trace
16:28.04 vasc yeah i suspect that could be done across the whole pipeline, but it requires rethinking the algorithm.
16:28.14 vasc it's probably non-trivial. but yeah it's worthwhile in the long run.
16:28.48 vasc i'm just kinda reticent about doing it first hand without understanding how the current algorithm works properly.
16:29.14 vasc not just mechanically but in terms of performance as well.
16:29.40 Stragus My raytracer used an inlined callback, the user could do whatever it wants with the hits. They can be processed on the fly (recommended) or buffered by a custom solution in the callback. And importantly, the inlined callback can terminate rays early
16:29.48 vasc especially considering the guys who originally wrote the code didn't do it, and they worked on it for decades.
16:30.10 vasc well, we kind of have something like that,
16:30.36 vasc there's no storing of segments in the single pass version of the renderer.
16:30.45 Stragus Cool. Is the callback truly inlined? You want to avoid any function call on GPU, especially function pointers
16:30.45 vasc but that doesn't do CSG.
16:31.09 vasc and it only returns the first hit, or an accumulation of the result of all the hits.
16:31.28 vasc you can't have function pointers on opencl.
16:31.40 vasc but yeah its some function.
16:31.45 Stragus Eheh. You can with CUDA, but it's a Very Bad Idea anyway
16:32.38 mdtwenty[m] i was doing it wrongly :D
16:32.58 vasc that version of the renderer is way faster than the current ANSI C one.
16:33.04 mdtwenty[m] i got 493 maxdepth for the goliath and 105 for the havoc
16:33.12 vasc but it doesn't do CSG so it isn't a proper comparison
16:33.16 vasc really?
16:33.21 vasc it's still way more than i expected.
16:33.32 Stragus vasc: I'm sure. My raytracer of triangles reached a billion rays per second... while a CPU core does 20M per second at most
16:33.44 Stragus (SSE optimized CPU code)
16:33.56 vasc mdtwenty[m], what's the amount of primitives in each scene?
16:34.33 vasc just for curiosity's sake.
16:35.06 vasc i think there's a 'list' command in mged or something
16:35.25 mdtwenty[m] goliath has 10499 primitives and havoc 2429
16:35.46 vasc pfew, it's still smaller at least.
16:35.58 vasc but...
16:36.09 Stragus There could be some ray hitting a bunch of aligned screws? :)
16:36.10 mdtwenty[m] well the good news is that the boolean weaving doenst crash
16:36.49 vasc well it might use an outrageous amount of memory.
16:37.10 vasc so perhaps Stragus will get his thing.
16:37.26 vasc :-)
16:37.48 vasc the havoc with 105 is ok i guess.
16:37.51 vasc but 493
16:38.10 vasc that's 16 double words
16:38.25 vasc i.e. cl_uint [16]
16:38.41 mdtwenty[m] yeah i got 493 while rendering with the front view
16:39.09 vasc can you compute the amount of memory that would take with that size of bitvector?
16:39.17 vasc the whole segments array
16:39.39 Stragus Why use the max depth for a ray though? Why not compute the sum of all rays, through a reduction kernel, if you are going to perform an identical trace right away?
16:40.08 vasc we have a bitvector we use inside each ray's segment list
16:40.15 Stragus (I still prefer dynamically allocated memory, but your way would work fine, except for the tracing-twice thing)
16:41.00 vasc well
16:41.02 vasc it's like
16:41.06 vasc we have a list of segments
16:41.11 vasc which gets computed into a list of partitions
16:41.44 vasc and then that gets evaluated
16:42.05 Stragus So each ray computes how much storage it requires, it stores that number, and you reduce all these numbers to a grand total?
16:42.13 vasc each segment only belongs in one object right? but the partitions can belong to more than one.
16:42.30 vasc like the ray pierce one and exits the other. but it's the same partition solid space.
16:42.52 vasc yeah its kinda like that.
16:43.22 vasc but that's only used to compute the amount of space we'll need.
16:43.30 vasc the actual algorithm isn't just a reduction.
16:44.17 Stragus Right... but what I'm saying is that it doesn't matter if the "max depth" is 40000 due to a bunch of aligned screws somewhere
16:44.25 Stragus You want the total for all rays
16:44.38 vasc mdtwenty[m], another thing we could do is dynamically allocate the bitvector, so rays with more segments would get larger bitvectors, but i wonder if that would complicate the code too much.
16:45.22 vasc hmm
16:47.59 vasc so it's max_partitions*sizeof(cl_partition_without the bitvector)+max_partitions*sizeof(cl_uint)*(493/32)
16:48.09 vasc how much is that in bytes?
16:48.17 vasc mdtwenty[m]
16:48.44 vasc and this max_partitions is the total amount of partitions for all the rays.
16:48.53 vasc sum
16:49.48 mdtwenty[m] one sec
17:03.16 vasc hmm
17:03.31 vasc perhaps this is not as a big of a deal as i thought
17:04.22 vasc +struct cl_partition {
17:04.22 vasc + struct cl_seg inseg;

17:04.51 vasc <PROTECTED>
17:04.53 vasc };
17:04.55 vasc so
17:04.57 vasc who cares.
17:05.03 *** join/#brlcad teepee (~teepee@unaffiliated/teepee)
17:05.35 vasc it's like just a cl_hit has 8+8+8+2+1 words
17:05.39 vasc double words
17:05.57 vasc i.e. 27
17:06.25 Stragus That cl_hit struct is kind of heavy, like 84 bytes
17:06.29 vasc and each partition has like 6 of those
17:07.10 vasc so using even 16 double words for the bitvector seems pathetic in comparison.
17:07.50 vasc still i'm kinda interested to know how much memory the whole thing uses right now.
17:08.29 vasc Stragus, it's much, much worse than that.
17:08.43 vasc coz cl_double3's are ACTUALLY cl_double4s.
17:09.15 vasc it's an opencl thing.
17:09.40 vasc and then there's struct alignment
17:09.49 vasc which reminds me
17:09.58 vasc mdtwenty[m], instead of this:
17:10.22 vasc +struct cl_partition {
17:10.22 vasc + struct cl_seg inseg;
17:10.22 vasc + struct cl_hit inhit;
17:10.22 vasc + struct cl_seg outseg;
17:10.22 vasc + struct cl_hit outhit;
17:10.23 vasc + cl_uint segs; /* 32-bit vector to represent the segments in the partition */
17:10.24 vasc +};
17:10.27 vasc try this:
17:10.38 vasc +struct cl_partition {
17:10.38 vasc + struct cl_seg inseg;
17:10.38 vasc + struct cl_seg outseg;
17:10.38 vasc + struct cl_hit inhit;
17:10.38 vasc + struct cl_hit outhit;
17:10.39 vasc + cl_uint segs; /* 32-bit vector to represent the segments in the partition */
17:10.41 vasc +};
17:10.46 vasc and see if it's sizeof() is smaller.
17:11.01 Stragus That shouldn't make a difference, both cl_hit and cl_seg have the same alignment
17:11.08 vasc i hope so.
17:11.55 Stragus If these cl_double3 waste memory, then perhaps it should be packed differently
17:11.58 vasc its the buildin cl_types that are an issue usually.
17:12.02 vasc builtin
17:12.45 Stragus Although frankly, this whole data storage scheme is very unfriendly to GPUs and SIMD
17:12.55 vasc hm
17:13.05 vasc only because it isn't z-orderered.
17:13.09 vasc oh i see.
17:13.34 vasc well
17:13.39 Stragus No! Because you will have scattered loads/stores all over
17:13.48 Stragus All memory transactions will be 8 times slower than necessary
17:14.10 vasc the thing is you probably don't need the whole thing across all stages of the algorithm
17:14.20 vasc so you could fraction this
17:14.33 vasc and increase memory locality.
17:14.39 Stragus For best performance, all threads of a warp/wavefront need to access consecutive memory addresses
17:14.44 *** join/#brlcad merzo (~merzo@194.140.108.146)
17:15.01 Stragus So you need some struct where struct foo { float x[32]; float y[32]; etc. };
17:15.02 vasc its like i said, you don't need to whole thing.
17:15.07 vasc even before that.
17:15.45 vasc yeah i know but if we minimize the size of the elements it ain't a big deal.
17:15.59 vasc the problem is the structs are too fat right now.
17:16.20 vasc still
17:16.35 vasc in comparison to the ANSI C code, it's incredibly memory coherent ya know?
17:16.40 Stragus Not a big deal? The stride between elements doesn't matter unless it's in the same cache lines
17:17.00 Stragus Well, these memory operations will be 8 times slower than if they were reorganized differently
17:17.14 Stragus That may or may not be a bottleneck, you'll decide that
17:17.31 vasc even with a cache?
17:17.34 vasc i'm not sure about that.
17:17.53 vasc i think the main issue is to have poor memory locality in accesses.
17:18.00 vasc rather than the access patterns themselves.
17:18.41 Stragus It's not about the cache, it's about memory transactions
17:18.52 vasc memory bank conflicts?
17:19.00 Stragus I am very sure about that, been doing CUDA for 8 years, and probably the biggest helper in #cuda...
17:19.16 Stragus Bank conflicts are for shared memory
17:19.58 vasc well the thing is
17:20.09 vasc if you're gonna need to access the rest of the struct in the same kernel
17:20.29 vasc it's all going to have to be loaded anyway.
17:20.30 Stragus Presumably, all threads of the same warp/wavefront will also access the rest of their structs, no?
17:21.15 vasc that's the thing i said, i think we don't need to store everything in that struct in all the stages of the algorithm. it's just that currently we're slavishly following the way the existing ANSI C code is structured.
17:21.37 vasc like
17:21.54 Stragus Okay! But it should still be designed so that consecutive threads access consecutive values in memory
17:22.02 Stragus You don't want a stride between threads
17:23.08 vasc i'll give you an example. i thought about doing that in the intersections code.
17:23.29 Stragus Consecutive addresses is _the_ solution that is fast on all GPUs from all vendors, for all generations. Beyond that, there are particularities if the accesses are shuffled, out of order, with gaps between chunks of 128 bytes, etc.
17:23.33 vasc well it turns out each kernel still has so many branches. a lot of threads will be idling and it's awfully low performance.
17:23.46 vasc the GPU isn't maxed out.
17:23.57 Stragus All right. But the threads that are active would still access a bunch of packed addresses
17:24.09 vasc no it's actually terrible.
17:24.33 vasc imagine one thread is doing a quadric like a sphere, and the other is doing a thorus intersection.
17:24.55 Stragus Indeed, paths should be merged as much as possible. Coherent rays can help a lot with that
17:25.14 vasc well i thought about that. that actually kind of happens as it is.
17:25.28 vasc since i'm using a thread block.
17:25.30 vasc but
17:25.36 Stragus If there are some common operations between spheres and thorus, like storing data (memory transactions), they should be merged together
17:25.46 vasc i think the best thing would be to reorder the intersection calculations.
17:25.47 Stragus As little code as possible should be specific to branches
17:25.57 Stragus That's possible, yes
17:26.21 vasc like group the ones that use the same kernel solver together.
17:27.18 vasc but the whole existing ANSI C code is more built to minimize the amount of operations than either memory consumption, or maximize memory coherency
17:27.18 Stragus It's possible to have warp-wide votes to decide how many threads need to perform operation X, before deciding to do it with a bunch of threads
17:27.38 vasc or minimize branches
17:27.38 Stragus But these aren't as critical issues as properly organizing memory. Reshuffling memory implies rewriting a lot of code, so it must be done early
17:27.59 Stragus Right, it's very different to optimize for scalar execution and for wide parallelism
17:28.09 vasc its not just that
17:28.16 vasc it's optimized for 1980s machines
17:28.20 Stragus Oh I see, yes
17:28.32 Stragus Memory was fast, ALUs were slow. And now it's the other way around
17:28.35 vasc yep+
17:31.01 vasc so mdtwenty[m] any luck with that?
17:33.19 mdtwenty[m] sent a long message: mdtwenty[m]_2017-06-23_17:33:18.txt <https://matrix.org/_matrix/media/v1/download/matrix.org/hVZtHbkIpDKOvbklzQAQwlpz>
17:33.39 vasc ok
17:33.47 vasc what about the memory size of the whole thing?
17:35.35 vasc <vasc> hmm
17:35.36 vasc <vasc> so it's max_partitions*sizeof(cl_partition_without the bitvector)+max_partitions*sizeof(cl_uint)*(493/32)
17:35.36 vasc <vasc> how much is that in bytes?
17:35.36 vasc <vasc> mdtwenty[m]
17:35.36 vasc <vasc> and this max_partitions is the total amount of partitions for all the rays.
17:35.38 vasc <vasc> sum
17:35.41 mdtwenty[m] i got 2337015024
17:35.55 mdtwenty[m] for the goliath that has 493 depth
17:36.35 vasc 2 GB?!
17:37.04 vasc ok, how much is max_partitions*sizeof(cl_partition_without the bitvector) alone?
17:37.39 mdtwenty[m] compiling
17:39.06 mdtwenty[m] 2 179 756 800
17:39.49 vasc also i wanna see the code for bool_Eval
17:39.59 vasc so the bitvectors aren't the real problem
17:40.16 vasc since they use a "mere" 200 MB or less.
17:40.31 vasc ok i think i got the idea
17:40.36 vasc +struct cl_partition {
17:40.36 vasc + struct cl_seg inseg;
17:40.36 vasc + struct cl_hit inhit;
17:40.36 vasc + struct cl_seg outseg;
17:40.37 vasc + struct cl_hit outhit;
17:40.37 vasc + cl_uint segs; /* 32-bit vector to represent the segments in the partition */
17:40.39 vasc +};
17:40.41 vasc +
17:40.53 vasc instead of storing copies of the cl_segs, why not use indexes instead?
17:41.51 mdtwenty[m] yes i think that it would work
17:43.40 vasc ((8*4*3+8+4)*2+4)*2 vs 4*2
17:43.45 vasc 440 vs 8
17:43.56 vasc that should shrink things down
17:47.10 vasc so you have the code for bool_eval so i can look at it? i kind of want to understand which data in the partitions will get accessed in rt_boolfinal and rendering.
17:49.30 mdtwenty[m] posted a file: ocl_bool_eval.patch (51KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/SFtMrGVveJAkLiBFABODKZMf>
17:49.40 mdtwenty[m] this should be it
17:51.27 vasc ok
17:51.40 mdtwenty[m] i think that only the segments in the partition are relevant for boolean evaluation and shading
17:51.48 vasc rt_boolfinal seems to hammer a partition's inhit/outhit .hit_hist's over and over.
17:52.01 vasc .hit_dist
17:52.11 vasc and then it computes segment regions
17:54.50 vasc in a later optimization we may want to simplify the partition structures.
17:55.03 vasc struct cl_hit {
17:55.03 vasc <PROTECTED>
17:55.03 vasc <PROTECTED>
17:55.03 vasc <PROTECTED>
17:55.03 vasc <PROTECTED>
17:55.04 vasc <PROTECTED>
17:55.06 vasc };
17:55.15 vasc of all of this, it looks as if rt_boolfinal only accesses the hit_dist.
17:55.31 vasc i think the rest is only accessed in the final rendering stages.
17:56.14 vasc but for now, just not storing the whole cl_segs in the cl_partitions should be enough.
17:57.21 Stragus Eh, still keep in mind that repacking of hits in structs of arrays of 32 or 64
17:58.09 vasc well the current code is horrible in several ways.
17:58.25 vasc just the amount of memory copies going on is kind of insane.
17:58.34 vasc i'm surprised it's as fast as it is.
17:58.44 Stragus How "fast" is fast? :)
17:59.11 Stragus The reference CPU code is also abysmally slow, so it's not a great point of comparison
17:59.44 vasc mdtwenty[m], after you use indexes instead of storing the whole cl_segs, test goliath and havok again. tell me the time it takes and if it crashes or not.
18:00.00 vasc Stragus, well it's what we have.
18:00.26 vasc mdtwenty[m], once you get that working, it's time to work on rt_boolfinal
18:00.54 vasc mdtwenty[m], oh and tell me how much memory it uses to store the partitions now vs what it used before.
18:01.05 vasc with the indexes.
18:01.10 mdtwenty[m] and what about the bitvector for now?
18:01.25 vasc yes, use the dynamic bitvector too
18:01.35 vasc i paste the code above? did you get it?
18:01.37 vasc pasted
18:01.59 vasc <vasc> ok found it
18:01.59 vasc <vasc> == host
18:01.59 vasc <vasc> cl_uint ND = N/WORD_BITS + 1;
18:01.59 vasc <vasc> mD = clCreateBuffer(gpuCtx, CL_MEM_READ_WRITE, sizeof(cl_uint) * ND, NULL, NULL);
18:01.59 vasc <vasc> == device
18:02.00 vasc <vasc> inline uint bindex(const uint b) {
18:02.02 vasc <vasc> return (b >> 5);
18:02.04 vasc <vasc> }
18:02.06 vasc <vasc> inline uint bmask(const uint b) {
18:02.08 vasc <vasc> return (1 << (b & 31));
18:02.10 vasc <vasc> }
18:02.12 vasc <vasc> inline uint isset(__global uint *bitset, const uint b) {
18:02.14 vasc <vasc> return (bitset[bindex(b)] & bmask(b));
18:02.16 vasc <vasc> }
18:02.18 vasc <vasc> inline uint clr(__global uint *bitset, const uint b) {
18:02.20 vasc <vasc> return (bitset[bindex(b)] &= ~bmask(b));
18:02.22 vasc <vasc> }
18:02.24 vasc <vasc> inline uint set(__global uint *bitset, const uint b) {
18:02.26 vasc <vasc> return (bitset[bindex(b)] |= bmask(b));
18:02.28 vasc <vasc> }
18:02.30 vasc <vasc> -
18:02.32 vasc <vasc> this is my code, so i give you permission to it for any purpose.
18:02.34 vasc <vasc> where WORD_BITS is 32 since 'D' is an array of cl_uints
18:02.35 vasc <vasc> and N is the amount of bits you want the bitvector to have.
18:03.10 vasc basically you have a cl_uint array per bitvector
18:03.32 vasc and you an use the isset, clr, or set functions to twiddle the bits.
18:03.39 vasc or query them.
18:04.48 vasc for a start you can just use a cl_uint segs[16]; or whatever
18:04.59 vasc but eventually you want to dynamically determine the size of this
18:05.39 vasc the quick and dirty way to do it, is basically to pass it as a #define before the kernels are compiled.
18:06.07 vasc but don't do that.
18:06.28 vasc we'll probably need to optimize this some other way. but without more tests, it's hard to determine the appropriate solution,.
18:07.05 Stragus That bitvector is to determine entry/exit status through solids?
18:07.15 vasc no
18:07.29 vasc it states which segments are within a partition
18:07.43 vasc it's per ray
18:08.01 vasc we could do this some other way though
18:08.01 Stragus Okay. I guess I'm not familiar enough with the terminology used by the BRL-CAD raytracer
18:08.27 vasc if the bitvector is too sparse, we would probably be better off with using a list, like the current code already does.
18:09.11 Stragus Without knowing what the bitvector was, that was my thought
18:10.31 vasc well.
18:10.47 vasc i thought there would be less depth complexity in the average scene than ther actually is.
18:10.50 vasc my mistake.
18:11.35 vasc a typical game scene has like 3 depth complexity.
18:12.05 vasc in here we don't cull stuff.
18:12.28 vasc i thought 32 was enough. so much for that.
18:12.38 *** join/#brlcad teepee (~teepee@unaffiliated/teepee)
18:13.28 vasc i know there are hard limits in the amount of intersections per ray on triangle meshes in the current code for example.
18:15.59 vasc https://svn.code.sf.net/p/brlcad/code/brlcad/trunk/src/librt/primitives/bot/tie.c
18:16.06 vasc <PROTECTED>
18:17.32 vasc mdtwenty[m], if the bitvector is too slow on the goliath scene, we'll have to use lists again...
18:18.29 mdtwenty[m] ok, i will change the bool weave to use the indexes for segments intead of the segs and will test
18:18.35 vasc ok
18:22.20 vasc hm
18:23.00 vasc so this is what the ANSI C code does for bool_eval of solids.
18:23.02 vasc case OP_SOLID:
18:23.02 vasc <PROTECTED>
18:23.02 vasc register struct soltab *seek_stp = treep->tr_a.tu_stp;
18:23.02 vasc register struct seg **segpp;
18:23.02 vasc for (BU_PTBL_FOR(segpp, (struct seg **), &partp->pt_seglist)) {
18:23.03 vasc <PROTECTED>
18:23.05 vasc ret = 1;
18:23.07 vasc goto pop;
18:23.09 vasc <PROTECTED>
18:23.11 vasc }
18:23.13 vasc ret = 0;
18:23.15 vasc <PROTECTED>
18:23.17 vasc <PROTECTED>
18:27.39 vasc so
18:28.00 vasc you need to know if a partition has a solid in it
18:31.31 mdtwenty[m] a solid?
18:33.43 vasc a solid is basically a primitive object.
18:33.54 vasc like a sphere.
18:34.03 vasc in brlcad parlance.
18:35.08 vasc a solid object.
18:39.01 vasc i'll go jog for a while. should be back in 30-45 mins
18:39.56 mdtwenty[m] Ok :) i will also take a break to get dinner
19:04.28 *** join/#brlcad DaRock (~Thunderbi@mail.unitedinsong.com.au)
20:17.32 vasc .
20:38.16 mdtwenty[m] so i changed the struct partition and it is working fine.. i am working on the dynamic bit vector right now
20:39.35 vasc good. make sure to make a backup. :-)
20:40.12 vasc you'll have to initialize the data though
20:40.30 vasc prolly the easiest way is to bzero the memory before using it.
21:03.27 mdtwenty[m] ok i will have to leave the house for a bit and probably will only get back to this tomorrow morning
21:05.17 mdtwenty[m] i will notify you once its done
21:07.27 vasc ok
21:08.42 vasc see you later then!

17:00.02 vasc hi mdtwenty[m]
17:28.51 mdtwenty[m] hey
17:30.31 mdtwenty[m] so the other day i tried the goliath scene with a cl_uint[16] bitvector first and it would take too much time to weave the segments
17:32.23 mdtwenty[m] so i started to make some changes to the weave kernel to use a list structure instead of the array
17:35.54 mdtwenty[m] the solution with the list is fast, but i am still trying to find the cause for some missing partitions when testing with csg scenes evolving difference operations
17:37.45 vasc well, the array is slow with your present code for several reasons
17:38.20 vasc like that this:
17:38.21 vasc + pp = &partitions[offset];
17:38.21 vasc + //iterate over segments of partition
17:38.21 vasc + for (uint i = pp->segs_start_index; i < pp->segs_start_index + pp->segs_in_partition; i++) {
17:38.21 vasc + if (segs_in_pp[i].seg_sti == st_bit) {
17:38.22 vasc + ret = 1;
17:38.24 vasc + break;
17:38.26 vasc + }
17:38.28 vasc + }
17:39.14 mdtwenty[m] yes, also inserting partitions on the array
17:40.47 mdtwenty[m] the solution with 2 ints to reference the back and forward partition is fast
17:40.59 mdtwenty[m] compared with the array version
17:41.07 vasc well
17:41.15 vasc i don't know if something like that can work really.
17:42.06 vasc did you keep the other version you made friday someplace?
17:42.24 vasc the one with the bitvector which didn't use whole segs but indexes
17:42.45 vasc also
17:43.01 mdtwenty[m] yes i made a backup with that version
17:43.11 vasc good. keep that just in case.
17:43.24 vasc in fact send it to me.
17:45.53 vasc the thing is, without profiling the code, it's hard to know it its better to use the list or the bitvector.
17:46.09 vasc like, what's the min and max size of the lists, or the average.
17:46.41 vasc and how ofter is bu_ptbl_ins_unique used vs a plain list traversal
17:46.44 vasc and so on
17:47.51 vasc this is something which could be found out by instrumenting the ANSI C code and printing an instruction count out or something like that.
17:48.46 vasc you can't optimize the code without knowing the data and the access patterns
17:48.48 mdtwenty[m] posted a file: weave_segs_cl_uint16.patch (51KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/gptQETCBWOirrbuoOVcaPlwv>
17:52.09 vasc so i think you should instrument the code and this out.
17:52.40 vasc 1) what's the min and max size of the lists, and the average. 2) how often is bu_ptbl_ins_unique used vs a plain list traversal.
17:53.07 vasc i suspect the list is only traversed in the bool_eval phase.
17:53.57 vasc right. take this example code:
17:53.59 vasc + pp = &partitions[offset];
17:53.59 vasc + //iterate over segments of ray
17:53.59 vasc + for (uint k=h[id]; k!=h[id+1]; k++) {
17:53.59 vasc + if ((pp->segs[(k-h[id])/32] & (1 << (k - h[id]) % 32)) != 0) {
17:53.59 vasc + RESULT_TYPE segp = segs+k;
17:54.00 vasc + if (segp->seg_sti == st_bit) {
17:54.02 vasc + ret = 1;
17:54.04 vasc + break;
17:54.06 vasc + }
17:54.08 vasc + }
17:54.10 vasc + }
17:54.12 vasc you're gonna execute this for every partition right?
17:54.21 mdtwenty[m] yes
17:54.31 mdtwenty[m] it checks for every partition
17:54.39 vasc this is too slow i think this would be faster if the loop was inverted.
17:55.21 vasc forall i in 0..15
17:55.59 vasc you check if there are set bits in that bitvector, and if there are
17:56.26 vasc then you check if that segment's seg_sti is equal to the st_bit
17:56.47 vasc it seems slow right? coz its 16*32 iterations
17:56.54 vasc but it's a sparse bitvector
17:57.13 vasc so you don't need to iterate over all bits, just the ones that are one
17:57.32 mdtwenty[m] yes i could try that
17:57.37 vasc you can use popcnt to know how many bits are set.
17:57.52 vasc even better use ffs.
17:58.03 vasc there isn't an ffs function in opencl but you can do one with clz.
17:58.08 vasc i mean
17:59.23 vasc like
17:59.44 vasc you iterate the bitvector
17:59.56 vasc and for each segs[i]
18:00.07 vasc you use clz(pp->segs[i])
18:00.41 vasc and while its != 32
18:00.51 vasc you extract that bit and test it
18:01.05 vasc or something like that.
18:01.34 mdtwenty[m] hm yeah i will try that
18:01.35 vasc i think clz is like 1-cycle.
18:02.11 vasc its not perfect but it should be less bad.
18:02.23 vasc we need to profile the code to know if its better to build the list or not.
18:02.26 mdtwenty[m] but i also think that one of the problems is with inserting partitions in the partitions array
18:02.32 mdtwenty[m] at least for huge scenes like the goliath
18:02.55 vasc possibly. for that you need to use a linked-list instead of an array i guess.
18:03.29 vasc the ANSI C code uses double-linked lists but i think you only need a single-linked list.
18:04.30 vasc but i'm not sure.
18:05.13 vasc so you're working on that?
18:05.24 mdtwenty[m] i started implementing a list to store the partitions, and the goliath scene would only take 0.55 sec or something IIRC, against the 40+ sec with the array version
18:06.25 vasc nice.
18:06.32 mdtwenty[m] there is still some issues with some missing partitions for scenes with difference operators
18:06.52 vasc show me the code and i can help debug if you want.

18:15.52 mdtwenty[m] ok this should be it
18:16.15 mdtwenty[m] is still a work in progress
18:19.54 mdtwenty[m] intersections and unions seems to be working
18:20.43 mdtwenty[m] at least with the simple scenes that i have for testing
18:21.12 mdtwenty[m] but without rt_boolfinal implemented it is hard to test with other scenes
18:22.50 vasc seems kinda wonky
18:28.13 vasc take this:
18:28.14 vasc <PROTECTED>
18:28.15 vasc + uint start_index = 2 * h[id];
18:28.15 vasc + tail_pp = append_partition_pp(partitions, ipartition, id, start_index);
18:28.15 vasc +uint append_partition_pp(global struct partition *partitions, global uint *ipartition, size_t id, uint start_index)

18:28.17 vasc + uint new = start_index + ipartition[id];
18:28.19 vasc + uint old = start_index + ipartition[id] - 1;
18:28.21 vasc +
18:28.23 vasc + if (ipartition[id] == 0) {
18:28.25 vasc + //No partitions yet
18:28.27 vasc + partitions[new].back_pp = new;
18:28.29 vasc + partitions[new].forw_pp = new;
18:28.31 vasc + return start_index;
18:28.33 vasc + }
18:28.35 vasc +
18:28.37 vasc + partitions[new].back_pp = old;
18:28.39 vasc + partitions[new].forw_pp = new;
18:28.41 vasc + partitions[old].forw_pp = new;
18:28.43 vasc + return new;
18:28.45 vasc +}
18:28.47 vasc why not call as append_partition_pp(partitions+start_index, ipartition, id); instead?
18:28.55 vasc that would eliminate one variable.
18:29.17 vasc as for the code in append_partition_pp....
18:30.15 vasc while it's not the case in this particular instruction
18:30.26 vasc i thought you needed to insert the element at the end?
18:30.53 vasc unless you're doing this like a C++ linked list
18:31.08 vasc with a bogus node on the beggining which points to the end and start of list or something.
18:32.14 vasc also you could just pass ipartition[id] since you never use each value seperately.
18:32.54 vasc oh right.
18:33.01 vasc ipartition says how many partitions there are
18:33.04 mdtwenty[m] noted! and yes i use only the functions to update the back_pp and forw_pp values
18:33.05 vasc so it points to the end of list
18:33.15 vasc well
18:34.14 vasc i disagree with this:
18:34.15 vasc <vasc> + if (ipartition[id] == 0) {
18:34.15 vasc <vasc> + //No partitions yet
18:34.15 vasc <vasc> + partitions[new].back_pp = new;
18:34.15 vasc <vasc> + partitions[new].forw_pp = new;
18:34.15 vasc <vasc> + return start_index;
18:34.17 vasc <vasc> + }
18:34.32 vasc i think should be partitions[new].back_pp = partitions[new].forw_pp = 0;
18:34.52 vasc if there's nothing else in the list there's no next or prev node.
18:36.04 vasc in fact its better to just
18:36.22 vasc i think should be partitions[start_index].back_pp = partitions[start_index].forw_pp = 0;

18:37.39 vasc or something
18:38.06 vasc the circular references are kinda weird.
18:38.21 vasc so you basically know if its the end or start of the list because of the circular reference?
18:38.23 mdtwenty[m] yes and i think the issue comes from that
18:38.48 mdtwenty[m] ye that was my idea
18:39.17 vasc it can be done that way i guess, but usually we just say there's no next or prev with a null pointer.
18:39.19 vasc hm
18:39.23 vasc now that i think about it
18:39.34 vasc 0 itself is a valid position in our case
18:39.39 vasc so you would have to use -1 or something
18:39.44 vasc or MAX_INT
18:40.30 vasc MAX_UINT ~0
18:40.42 vasc i guess your way also works
18:40.53 vasc its just not very conventional...
18:42.01 mdtwenty[m] and i am having trouble when there is only 1 partition
18:43.55 mdtwenty[m] i think it makes more sense having the forw and back set to 0 if there is no previous/next partition
18:45.05 vasc nah i can't be 0 because 0 is also a valid position
18:45.07 vasc it
18:45.37 mdtwenty[m] j = partitions[head_pp].back_pp; j != partitions[j].forw_pp; j = partitions[j].forw_pp)
18:45.41 vasc your way of doing it with the circular references is ok.
18:45.59 mdtwenty[m] when there is only 1 partition this for doenst work
18:46.46 vasc wtf.
18:47.11 vasc hm
18:48.43 vasc well
18:48.55 vasc the thing is your current code always skips the last element of the list from i see.
18:49.20 vasc instead of using a while you need to use a do loop.
18:49.26 vasc and you need to check for an empty list.
18:49.29 vasc or something like that.
18:51.02 vasc if its a one element list it skips the one element. or would it you didn't have that ipartition[id] == 1 check in there.
18:51.13 vasc but in lists > 1 it skips the last element in the list as well.
18:53.22 mdtwenty[m] hm yes i see that
18:53.53 vasc or terminate the list with something other than a circular reference.
18:54.29 vasc otherwise you can't disambiguate between the last element and being past the last element.
18:54.53 vasc without extra checks.
18:55.39 vasc we can use 0 because its also a valid position
18:55.41 vasc so
18:55.46 vasc MAX_UINT
18:56.04 vasc is NULL

20:36.06 vasc well, it's a performance hog to call it too often.
20:36.18 vasc we're better off with regular memory pools.
20:38.56 vasc malloc and free need to have support for variable blocks, degrag, etc, this has a negative performance impact.
20:39.14 vasc defrag
20:47.20 Stragus I think of malloc/free like the rand() of memory management. Useful to get started, not for real code
20:47.41 Stragus wrote his own memory manager about a decade ago and never looked back
20:48.25 vasc most of the time it's not necessary to have something which supports variable sized blocks anyway.
20:49.02 Stragus Indeed, and if all you need are constant sized blocks, you can have an overhead approaching zero bytes per block
20:49.11 vasc yes.
20:49.12 Stragus malloc() is darn wasteful
20:49.45 vasc it's also a problem if you call it once per element, because of all the possible system calls.
20:50.04 vasc malloc implementations themselves usually buffer things.
20:51.01 vasc but malloc isn't omniscient. the programmer usually has more details on the type of memory uses to make something better than that.
20:51.09 Stragus And that behavior depends on the libc/OS. Linux loves to buffer things for higher malloc() performance, FreeBSD and Windows free aggressively
20:51.28 ``Erik O.o your malloc doesn't have to smell or look anything like the unix alloca malloc (which is generally split into like 4 different impls, with phkmalloc and whatever the one glibc/linux uses as the two big open source ones)
20:51.44 vasc first game i programmed on was an ANSI C MUD, it came with its own custom allocator because of that.
20:51.57 ``Erik like a diku?
20:52.01 ``Erik or circle?
20:52.04 Stragus Bottom line, use your own memory manager, and make it NUMA-aware
20:52.11 vasc yes. a Diku Merc Envy MUD.
20:53.03 vasc i ran one of the MUDs in our campus.
20:53.39 vasc so i programmed custom classes and things like that.
20:53.53 vasc first time I did socket programming.
20:55.06 ``Erik Stragus: I'd say that's bad advice for most programmers, most aren't able to do it better than the system and will introduce unnecessary and difficult bugs attempting, and the few that can will probably never hit that situation... you do weird shit, not everyone is as weird as you... :D
20:55.44 vasc malloc is a nice tool to have, but i think a memory pool abstraction would have been good enough for most people.
20:56.07 ``Erik off to the library and day care with me, Excelsior! https://www.youtube.com/watch?v=otOARxAOp2g
20:56.09 gcibot [ Excelcior!.wmv - YouTube ]
20:57.43 Stragus ``Erik: Then people should use whatever is written by people who know that stuff. :) No use should rand() either, people grab the Mersenne Twister or any other fancy RNG of the day
20:58.23 vasc problem with RNG is like you said with malloc, quality of implementation between OSes varies quite a lot.
20:59.11 vasc funilly enough, that MUD also had its own custom RNG...
20:59.58 vasc also its own custom string allocator.
21:00.03 Stragus I'll agree that rand() is a lot far worse than malloc()
21:00.43 vasc Shared String Manager i think was the name they gave it.
21:01.34 vasc i've also seen games have their own disk I/O functions and things like that.
21:03.08 Stragus Of course. Any reasonable game should have a thread dedicated to asynchronous disk I/O
21:04.09 vasc the network code in that MUD disabled naggle and did its own buffering.
21:05.05 vasc that was kind of fun afterwards in classes.
21:05.11 Stragus That Naggle buffering is terrible. You can feel the 200ms delay
21:05.39 vasc we had to write a non-blocking program. like everyone did it with UDP, and i did it with non-block TCP
21:06.03 vasc the teacher was kinda amazed i thought about it (we didn't learn that in class)
21:06.17 vasc well i had seen it before...
21:06.45 Stragus I once wrote an online game too, browser-based... but it was entirely written from scratch in C, it was its own HTTP server
21:06.56 vasc cool.
21:07.04 vasc i thought about doing something like that once.
21:07.13 Stragus Kind of crazy, it was so demanding in time and energy that I just gave it up one day
21:07.17 vasc MUDs are basically a sort of telnet server usually.
21:07.25 Stragus Also, I didn't know what I was doing so the code was terrible
21:07.44 vasc well HTTP has a lot of its own verbiage I guess.
21:07.57 Stragus Well, HTTP was just a tiny piece of the whole thing
21:09.16 vasc i thought about rewriting an http server, like lighthttpd or whatever it was called, or make an apache module out of it :-)
21:09.26 vasc or making an CGI
21:09.53 Stragus People expect a lot more interactivity from games these days
21:10.00 Stragus Mine generated HTML 3.0 stuff, eh
21:10.17 vasc well, those browser game can still be quite popular
21:10.22 Stragus It had a few thousand players (up to 2002 or so?), and I actually changed my online nickname because I felt bad answering questions from people who knew about it and asked where I had disappeared
21:10.34 vasc heh
21:10.40 Stragus Administrating an online game is a _lot_ of trouble
21:10.59 vasc i had enough trouble with like 100 college MUD players.
21:11.22 vasc when I was a Freeciv administrator we did have a game server... but I wasn't the main guy administrating it so...
21:12.04 vasc still I think it was useful to interact with the game players to figure out where to advance the game next, so I guess I messed with it more than the average maintainer.
21:12.10 Stragus I had set up an alert where the mods could make my computer play music to wake me up in the middle of the night if there was some serious problem/bug needing attention
21:12.22 vasc sheesh.
21:12.48 vasc i just let it crash and restarted it later :-)
21:13.05 vasc that's one good thing about games, people know stability isn't always up to scratch :-)
21:13.19 Stragus You feel bad about that when you have 4000 players logging in many times a day :)
21:13.38 Stragus So yes, it was way too stressful, but it was a good learning experience
21:13.40 vasc we did have an auto-restart script.
21:14.19 vasc and perioric saves.
21:14.23 vasc periodic
21:14.45 vasc one of the first things I did with Freeciv was rewriting the network code.
21:14.51 vasc it didn't use non-blocking sockets.
21:14.55 Stragus Darn
21:15.18 vasc it was really bad because it has simultaneous moves.
21:15.45 vasc sometimes people had lousy dial-up connections, their connection froze, and the OS timer was like 5 minutes.
21:15.54 vasc until it disconnected them.
21:15.56 Stragus My HTTP thing was a single thread, non-blocking sockets. It ran pretty smoothly, the whole universe "ticks" were taking 5 seconds (so the server would delay HTTP requests for 5 seconds every 10 minutes)
21:16.31 vasc yeah if it's well programmed its quite amazing the amount of connections you can multiplex with non-block TCP.
21:16.45 vasc people dismiss it too easily.
21:17.07 Stragus Well, you don't really want to go beyond a thousand sockets per thread
21:17.21 vasc Freeciv only has like, I dunno the limit now, but usually people played with like 16 player or 8.
21:17.59 Stragus I tried Freeciv and disliked many things about the gameplay
21:18.21 vasc well i only enhanced it, i wasn't one of the original authors :-)
21:18.31 Stragus :) Right
21:18.47 vasc i wrote a game client basically.
21:18.58 vasc at least that's how i started.
21:19.15 Stragus I still occasionally get brief dreams about writing a game. The last time was in 2013, I did that: http://www.rayforce.net/newproject024.png
21:19.34 vasc there's a lot of things i didn't like but it became really hard to refractor it without breaking backwards compatiblity.
21:19.48 Stragus The hydrography is actually computed by darn Computation Fluid Dynamics, with a water cycle and underground flow
21:20.03 vasc it looks nice.
21:20.35 Stragus I think I am way too perfectionist to ever finish something
21:20.50 vasc that's half the work to do a simple flight sim or strategy god game.
21:21.19 Stragus These trees? http://www.rayforce.net/newproject032.png - Procedurally generated from 200k triangles, then reduced by an algorithm to an optimal set of just 8 triangles to represent the best geometry with the least distorsion possible
21:21.32 Stragus And that algorithm was like 7k lines
21:22.00 Stragus I need to learn _not_ to aim for the best job I can do. Because it takes too darn long
21:22.05 vasc well good foliage can be really complicated. that's why most game engines used SpeedTree SDK...
21:22.23 vasc and i'm saying game engines not games.
21:22.58 Stragus I have a hard time using people's code, when I feel like I could write better
21:23.07 Stragus The problem is that "writing better" can take months
21:23.32 vasc i've wanted to design my own computer programming language more than once.
21:23.45 vasc it's not like i haven't written a compiler before.
21:24.14 Stragus I wouldn't personally go down that route
21:24.18 Stragus hugs and cuddles C
21:24.46 vasc well i've written design specs more than once. but never actually liked one of my language designs enough to go through with it.
21:25.34 Stragus I would add a few keywords to the C language, to provide more contextual information to the compiler to produce better assembly
21:25.39 Stragus But I wouldn't write a new language
21:26.38 vasc well.
21:27.00 vasc i had like module declaration and implementation like Modula-2, syntax like C, advanced array support.
21:27.10 vasc and I think I added SIMD to the specs.
21:27.44 Stragus GNU C has vector extensions
21:27.53 Stragus thinks of GNU C as the one true C
21:27.57 vasc it does. but opencl is a lot better.
21:28.37 Stragus Yes well, that targets different hardware, with completely different approaches and algorithms
21:30.23 vasc I mixed Pascal/Modula-2 and C
21:30.25 vasc so it was like
21:31.03 vasc func xpto(a, b, c: int) : (a, b: int)
21:31.25 vasc {}
21:32.07 Stragus Any advantage over C besides a different syntax? :)
21:32.36 vasc like you can see it supports multiple value return in functions.
21:32.44 vasc even if it's just syntatic sugar anyway..
21:32.50 vasc you can do that with a C struct.
21:32.57 Stragus Multiple return values is good
21:33.45 Stragus I wish C also had statements like break continue; instead of having to use goto
21:34.08 vasc i think i had that at one point, like break 2; or something.
21:34.11 Stragus And __attribute__((__may_alias__)) should be in the standard instead of that silly union thing
21:34.31 vasc but it seemed kinda messed up.
21:35.35 vasc i agree that it would be better to have some more control flow mechanisms.
21:36.08 vasc i can't say i'm a fan of C declarations though. or should I say C++ declarations.
21:36.17 vasc because if you look at K&R declarations they're nothing like that.
21:36.25 Stragus And I really would like to be able to tell the compiler the probability of each branch
21:36.44 Stragus __builtin_expect() is too absolute, it's like 100% or 0%
21:37.04 Stragus And compilers should obey the "register" keyword, darn it
21:37.32 vasc thing is sometimes there's register spills. so the compiler disables or ignore the hint.
21:37.51 Stragus And if you have a switch() without a default case and the input value isn't handled, it should be undefined behavior
21:38.06 Stragus I don't want a darn bound check every time I put a switch()
21:38.12 ``Erik pats swift O:-)
21:38.35 Stragus vasc: The hint is just ignored now because "compilers know better"
21:39.21 vasc well I looked at Nim some time ago ``Erik but it just seemed to have an overly complicated syntax.
21:39.49 vasc as for Swift is seems layered on top of the rest of the Apple runtime.
21:39.51 vasc it
21:40.42 Stragus I want more low-level control, and all new fancy languages "designed to replace C" tend to move _away_ from that
21:40.44 vasc and Go has a garbage collector so...
21:40.52 vasc exactly.
21:41.00 vasc they're pseudo-systems programming languages.
21:41.13 vasc they're Java wannabees rather than C replacements.
21:41.24 ``Erik nim kinda smells pythony
21:41.40 vasc like Go, it seems to be used mostly for what Java was used, network servers and the ilk.
21:42.00 ``Erik vasc: yeh, I've been doing ios code lately, so apple stack, arm cpu, etc...
21:42.10 vasc oh right forgot to mention Rust
21:42.17 ``Erik common lisp on the back end because I'm twisted
21:42.34 vasc i actually liked Common Lisp.
21:42.57 vasc you might hate it or love it, but the syntax makes sense for what it does.
21:43.06 vasc and it just feels right.
21:43.27 vasc problem is when you have to interact with the rest of the system, quite often its designed in C.
21:44.43 vasc oh right the complicated syntax is Rust, not Nim
21:45.11 vasc Nim's issue is garbage collection
21:46.02 vasc whenever someone claims to have written a "systems programming language" and then they add a garbage collector the features list.
21:46.09 vasc it's a hint they don't have a freakin clue.
21:46.51 vasc i mean its nice to just ignore memory allocation on a lot of programs
21:47.02 vasc but not on systems.
21:48.05 vasc i can guess what Linus would say about rewriting the kernel to use a garbage collected language.
21:48.55 vasc and as much as I hate Wirth, at least he followed people's advice and actually tried to write an OS kernel with his later languages.
21:49.59 vasc which is why Module-2 is so much better than Pascal. except it was too late for people to care about it.
21:50.03 vasc Modula-2
21:53.05 vasc other than C and OpenCL i like Python and Lisp
21:53.27 vasc Java is kinda ok.
21:53.47 vasc the frameworks are mostly horrible, horrible.
21:54.25 vasc Java itself, I think its good for what it was designed for, the only wart is the type system.
22:01.38 vasc oops gotta go

03:49.57 yukonbob q: (? not CAD related) -- reading docs for ksh (usually (always?) referring to pdksh), there is a note that it took inspiration from BRL shell. Does anybody know if that's BRL as in "Ballistics Research Laboritory"? A quick google search turned up nothing, but I'm curious what the details are...

17:24.30 d_rossberg gabbar1947: any additional questions?
17:25.18 gabbar1947 whats with the annot vs ant, mentioned by you
17:25.19 gabbar1947 ?
17:28.16 gabbar1947 I had mentioned in the mail, that there occurs a segmentation fault as soon as I inititalize anip->ant.count to any number in typein.c(annot_in()). Any idea as to why this happens
17:48.02 d_rossberg in include/rt/primitives/annot.h you use sometines _annot_ and sometimes _ant_
17:48.32 d_rossberg however, it looks like you mean the internal list when you use ant
17:51.37 gabbar1947 yes ant is the list
17:51.54 gabbar1947 annot is only referred in the case of internal object
17:52.07 d_rossberg then it's ok
17:55.18 gabbar1947 For the plot() function, we need to get the coordinates in the 3D space. For that I think we need the current plane of the screen (i.e. the unit vectors describing the plane of the screen). I had a look at the bview struct and was trying to proceed further.... Is there any other way to do this ?
17:58.56 d_rossberg and for the segmentation fault i would need to see your code
18:00.18 d_rossberg for the plat() function: did you got my mail i wrote today?
18:00.34 gabbar1947 Oh yess, just went through your mail !
18:01.04 gabbar1947 But still I think we will need the screen plane coordinates ?
18:02.09 d_rossberg you will need to know the "pixels per inch", but the displymanager should know about it
18:03.23 d_rossberg and the drawing functions in libdm draw directly to the screen (in pixels)
18:04.27 d_rossberg and, why do you call your patchfile .c
18:05.10 gabbar1947 haha ! sorry, was into .c files since the morning. I'll update
18:06.27 d_rossberg wait ..
18:06.38 d_rossberg it should be "
18:07.01 d_rossberg Copyright (c) 2017"
18:07.14 gabbar1947 okay
18:07.28 d_rossberg the files where created this year
18:13.43 d_rossberg that's all i can see for now
18:13.50 gabbar1947 This is what I was talking about. This is a snippet from the l_seg part of the sketch plot function. Here we have u_vec and v_vec that define the sketch plane, hence we can map the 2D coords to the 3D space. But in the case of annotations the plane of the screen is always the annotation plane, so we'll be needing the screen plane vectors, i suppose...
18:13.50 gabbar1947 VJOIN2(pt, V, sketch_ip->verts[lsg->start][0], u_vec, sketch_ip->verts[lsg->start][1], v_vec);

18:16.15 d_rossberg ~pastebin
18:16.15 infobot methinks pastebin is a web-based service where you should paste anything over 3 lines so you don't flood the channel. Here are links to a few: http://pastebin.ca, http://channels.debian.net/paste, http://paste.lisp.org, http://bin.cakephp.org/; or install pastebinit with yum or aptitude.
18:16.59 d_rossberg forget the sketch here
18:17.55 d_rossberg write the lines in an unmodified x-y plane and flag it as the display plane
18:18.14 d_rossberg then the display manager should know how to handle it
18:19.07 d_rossberg i.e. RT_ADD_VLIST(vhead, pt, BN_VLIST_DISPLAY_LINE_MOVE);
18:20.07 gabbar1947 Okay! will proceed accordingly. And one more thing, annotations always remain in the plane of screen, irrespective of the user rotating the entire model. I don't think the display manager will handle this thing, we'll have to handle it. is it?
18:22.15 d_rossberg of course the dm can handle this, and furthermore, only the displaymanager can handle this
18:23.32 d_rossberg if we would rely on the existing structures the dm could shift, rotate, and zoom it around
18:23.57 gabbar1947 Okay so for now, the priority is to add all the elements to the vlist and we need to define some functions in bn/vlist.h for its accomplishment. On it !
18:25.29 d_rossberg the hard part (but i don't think it's too hard) is to handle them in the displaymanagers
18:25.57 d_rossberg adding them to bn_vlist should be easy ;)
18:27.05 gabbar1947 So, we'll have to handle them for all display managers?
18:27.15 d_rossberg jep
18:31.54 gabbar1947 :)
18:33.57 gabbar1947 and regarding the seg fault, I've checked the import/export functions, there seem to be no issue with those. Do have a look if you get time, by the time I'll dive into vlist.h !
18:37.13 d_rossberg regarding the seg fault: the is no anip->ant.count in the typein.c i got
18:38.21 gabbar1947 It was commented previously, then we decided to remove the comments. Hence the line got removed
18:38.47 gabbar1947 just ( anip->ant.count = 1)
18:42.24 d_rossberg why not anip->ant.count = 0 ?
18:43.09 d_rossberg otherwise you had to allocate an rt_ant
18:45.16 gabbar1947 there seems to be no error with 0, but I was trying to include a line_seg, hence 1.
18:45.17 gabbar1947 <PROTECTED>
19:06.59 d_rossberg no, there isn't
19:09.38 d_rossberg you need to allocate memory for a pointer in segment, a line_seg, and write the address of the line segment memory to segment[0]
19:10.07 gabbar1947 I did that, still this issue persisted
19:11.16 d_rossberg then: show me your code ;)
19:11.24 gabbar1947 You can see this in the previous revisions of annot.c patch
19:11.49 gabbar1947 Wait, I'll have a look a look again, and get back to you
19:16.52 d_rossberg gabbar1947, i'll review, and hopefully commit, your patch tomorrow
19:17.59 d_rossberg and "look at a previous version and comment some (the right!) lines out" is a bad approach ;)
19:18.10 d_rossberg simply show me your code

15:32.52 vasc so wassup?
15:34.15 vasc you were looking at rt_boolfinal i think.
15:35.51 mdtwenty[m] i have been working on rt_boolfinal. At this moment i have created the 'regiontable', which contains the information about the regions involved in each partition
15:36.33 mdtwenty[m] and i evaluate the partitions against all the regions involved
15:37.20 vasc yes that is a good approach. once you figure out the data and the dataflow you've understood most of the problem.
15:37.43 mdtwenty[m] i still cant reproduce the same image for the operators.g scene, but that could be because of not resolving overlaping partitions yet
15:40.29 vasc well, once you have something you can test that you know should work, if have issues i can proofread it,.
15:41.18 vasc and do a code review.
15:41.46 vasc in fact, show me the new stuff you've written so i can have a look at it
15:43.16 vasc if you think it's too early we can do this later.
15:44.32 mdtwenty[m] sure, give me a second to get the diff file

15:54.37 mdtwenty[m] posted a file: rt_boolfinal_regiontable.patch (89KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/XWxfMEAVtuCheaqtgUFjtBVw>
15:55.16 mdtwenty[m] this doens't contains much yet.. apart from sending the regions to the kernel, and building the regiontable
15:55.36 mdtwenty[m] i also already started working on using shade_segs to shade the resulting partitions
15:56.06 mdtwenty[m] so you won't find the white shading code on the 'eval_partitions' kernel
15:57.41 mdtwenty[m] i'm using a private bitvector of 32 bits to represent the regiontable, but i plan to implement a dynamic bitvector once i have a working algorithm
15:59.29 vasc well i got a couple of things i can say just from looking at the datastructure....
16:00.35 vasc i'm not sure if the results of the evaluation of the partitions should be stored in that datastructure, or a separate data structure.
16:00.57 vasc and having pointers inside structs in opencl, like cl_bool_region does can be problematic.
16:01.09 vasc coz you see the memory map of the gpu and the cpu aren't the same.
16:01.45 vasc so the gpu may not be able to access data you allocated on the cpu. that's why you need to copy data around to opencl in the first place.
16:03.54 mdtwenty[m] noted, i will have a look at that
16:05.01 vasc there also might be struct alignment issues.
16:05.45 vasc make sure to put elements in the struct by order of size.
16:05.51 vasc biggest first.
16:06.08 vasc e.x. first doubles, then ints, then shorts, etc.
16:06.27 Stragus Struct alignment stuff should be quite identical for CPU and GPU codes
16:06.37 vasc don't be on it.
16:06.40 vasc i had problems.
16:06.50 vasc the code crashed until i reordered things around.
16:07.01 Stragus Are you sure that was the issue?
16:07.02 vasc don't bet on it.
16:07.09 vasc well, it stopped crashing.
16:07.18 Stragus Yes well... :)
16:07.38 Stragus That would be a very surprising compiler bug
16:08.14 Stragus I know sizeof(size_t) was wrong in CUDA 3.x (many years ago) only on OSX 64 bits. That was fun to debug without access to an OSX machine
16:08.17 vasc https://community.amd.com/thread/146853
16:08.19 gcibot [ OpenCL alignment | Community ]
16:08.22 vasc more people with vcrashing issues.
16:08.51 vasc i think i had problems with cl_double4s
16:10.06 vasc https://stackoverflow.com/questions/17361274/how-to-set-the-right-alignment-for-an-opencl-array-of-structs
16:10.06 gcibot [ gpu programming - How to set the right alignment for an OpenCL array of structs? - Stack Overflow ]
16:10.37 vasc and cl_double3s
16:10.55 Stragus Geez, why can't the C and OpenCL codes use the same darn struct
16:11.26 Stragus Well, that's terrible. I'm glad it has never been a concern with CUDA
16:12.59 vasc don't assume because something works some way in CUDA it works the same in OpenCL or vice-versa.
16:13.14 vasc they're quite similar but sometimes they're not.
16:16.51 mdtwenty[m] other thing that i noted is that the boolean tree in the rpn notation doesn't seem to differentiate reverse difference operations
16:17.13 mdtwenty[m] i.e: A-B and B-A produce the same tree
16:23.24 *** join/#brlcad HoloIRCUser3 (~holoirc@122.162.252.32)
16:25.08 vasc hm
16:25.33 vasc that shouldn't happen though
16:25.33 vasc the tree is followed in a specific order.
16:26.01 *** join/#brlcad sagarwal (~holoirc@122.162.252.32)
16:26.02 vasc so it should be like
16:26.13 vasc A B -
16:26.13 vasc vs
16:26.16 vasc B A -
16:27.38 mdtwenty[m] yes, i did some testing, by printing the normal tree, and the scene with reverse difference operation prints that
16:28.24 mdtwenty[m] but when printing the rpn tree i get A B - and A B -
16:28.34 vasc hm
16:28.45 vasc give me an example file that shows this
16:28.58 vasc i'll have to check that out later
16:29.23 mdtwenty[m] the scene operators.g contains it
16:30.31 vasc well it would be better with a simpler example..
16:30.36 mdtwenty[m] you can browse throught the geometry to draw only the region with that example
16:30.38 vasc if you can get one
16:41.13 mdtwenty[m] posted a file: reverse.g (0KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/uwWDpxvyQwVbKjAdqRmLLILp>
16:41.14 mdtwenty[m] here it is
16:43.46 vasc ok god it
16:43.47 vasc got
16:44.01 vasc i'll look at it later as i would need to reboot.
16:44.21 vasc meanwhile just try to get the same output as the ANSI C side.
16:44.33 vasc since that also uses the RPN tree with the patch.
16:45.19 mdtwenty[m] no worries, i just wanted to notify you about it
16:45.42 vasc no, it's good. i want to fix any bugs the code might have.
16:46.02 vasc i don't know if we'll use the RPN tree in the long run though. it's space and code efficient but it might not be computationally efficient.
16:46.09 vasc need to perform tests on that.
16:49.36 vasc but that's a long term concern.
16:53.39 mdtwenty[m] okay, i will keep working on rt_boolfinal (resolving overlaping partitions) to see if i can get the operators.g scene to render correctly
17:12.24 vasc i guess i need to read some compile papers.

18:09.17 Notify 03BRL-CAD:d_rossberg * 69941 (brlcad/trunk/include/bu/magic.h brlcad/trunk/include/rt/primitives/annot.h and 8 others): iterative patch from #469 (https://sourceforge.net/p/brlcad/patches/469/): latest annot_updated.patch from 2017-07-04, from Shubham Rathore "annot.c"...will be continued...
18:09.18 gcibot [ A 404 Error has Occurred ]
18:11.38 d_rossberg gabbar1947: any progress with the segmentation fault?
18:13.44 gabbar1947 https://paste.ee/p/i9lLv
18:13.44 gcibot [ Paste.ee - View paste i9lLv ]
18:13.56 gabbar1947 This is the code for the func
18:17.20 d_rossberg the first thing i see is that you allocate only one vertex
18:18.47 d_rossberg ...ok, it's for the text, not a line
18:19.02 gabbar1947 That was only for testing the function, once this works it can be extended to many vertices
18:24.33 gabbar1947 regarding the extension of the vlist, the line functionalities already exist, right? all we need to add is support for the text. So what does BN_VLIST_DISPLAY_LINE_MOVE, BN_VLIST_DISPLAY_LINE_DRAW exactly signify ? Or is it the mandatory placement in plane of the screen that differentiates LINE and DISPLAY_LINE ?
18:29.42 d_rossberg the segmentation violation is in rt_annot_export5() (src/librt/primitives/annot/annot.c:1217) - does this help?
18:31.11 gabbar1947 I had a doubt regarding the export5(), so I checked it previously ! I'll go through it again. This really helps !
18:31.51 d_rossberg maybe ant.reverse should be set to a good value too?
18:32.49 gabbar1947 https://www.irccloud.com/pastebin/f93ECx2O/
18:32.49 gcibot [ Snippet | IRCCloud ]
18:33.33 gabbar1947 I don't think not inititalizing ant.reverse will cause this error
18:34.15 d_rossberg the line where it crashes is: *(uint32_t *)cp = htonl(annot_ip->ant.reverse[seg_no]);
18:34.30 d_rossberg (line 1217 ;)
18:34.55 gabbar1947 Oh ! I see
18:35.20 d_rossberg btw, do you know how to use gdb (the gnu debugger)?
18:35.42 gabbar1947 Yes I've used gdb and ddd
18:35.53 gabbar1947 previously
18:36.10 gabbar1947 setting reverse will remove the error ..I think
18:36.11 d_rossberg this was the line gdb showed to me
18:39.54 gabbar1947 I'll build it again using the cmake DEBUG flag to make sure I don't encounter these kind of errors
18:42.09 gabbar1947 regarding the previous question ..... LINE and DRAW_LINE.. what are your views ?
18:44.42 d_rossberg BN_VLIST_DISPLAY_LINE_~ means that the coordinate it contains are screen coordinates, not 3d world coordinates
18:45.36 d_rossberg i.e. it has to use a different transformation matrix then for the BN_VLIST_LINE_~
18:46.10 gabbar1947 Get it.... then there will be a lot to change in the handling of dm's
18:46.30 d_rossberg ... some
18:46.56 gabbar1947 on it !
18:47.05 d_rossberg but you have to touch all of them
18:47.33 gabbar1947 Will surely do !
18:48.29 d_rossberg one you managed to retrieve the pixels-per-inch it should be easy
18:50.47 gabbar1947 for that I think I'll have to touch the model,view,projection matrices..
18:52.20 d_rossberg don't think so, you can very much draw directly to the screen
18:53.15 d_rossberg there is already a matrix wich transformes the reference point to pixels
18:53.40 d_rossberg then you have to draw some lines based to this pixel
19:02.49 gabbar1947 x-y plane can be chosen as the default plane for the lines, and then those coordinates can be mapped to the screen using the matrix mentioned by you
19:16.02 d_rossberg this was my idea
19:16.10 d_rossberg is crossing fingers
19:16.36 gabbar1947 credits to you !

15:34.30 gabbar1947 No, not Xcode
15:35.40 d_rossberg do you use cmake-gui?
15:36.35 d_rossberg when you initialize a new build with it, it gives you a list of known compilers
15:36.39 gabbar1947 No not the gui, everything is through the command line
15:37.24 gabbar1947 I'll modify the Cmakelists.txt for lldb and then check it out, once I finish the vlist functionalities
15:38.07 d_rossberg don't modify the CMakeLists.txt to do this!
15:38.42 d_rossberg really, use the gui, it makes many things simpler
15:39.09 gabbar1947 Sure, will try the gui. I'll figure it out for sure, no worries.
15:40.37 gabbar1947 I introduced bu_vls variable in vlist, I made another function for addition i. e. BN_ADD_LABEL_VLIST. All it does it is intialize the bu_vls struct as well, this way the BN_ADD_VLIST doesnt need to be changed for the vls. what do you think ?
15:41.11 d_rossberg you'll get the list of available compilers when you initialize a new build directory or clear the cache
15:42.20 d_rossberg maybe ;) I'll try it out when you uploaded you patch

12:11.44 vasc hey mdtwenty[m]
12:12.19 mdtwenty[m] Hey!
12:15.36 mdtwenty[m] About my last post on the dev log, i think that maybe there is an issue with the 'seg_sti' values of segments
12:22.08 vasc so why do you think those differ?
12:23.18 vasc something about the primitive intersector?
12:28.24 mdtwenty[m] it would be my guess, since the partitions seemed to have the right segments, because the segments have the same inhit.hit_dist and outhit.hit_dist
12:30.30 vasc one thing you could do is, like, find some pixels in a scene where that happens
12:30.50 vasc and then compare the output segments after store_hits, with the ones in the ANSI C version
12:31.01 vasc in those pixels
12:31.53 vasc hm
12:32.24 vasc are all the primitives in the file which fails, like supported?
12:34.20 vasc otherwise i wouldn't be surprised if there was a mismatch between primitive offsets in the OpenCL primitives array, and indices in the ANSI C code.
12:35.08 vasc we probably need to pass an extra array with the ANSI C primitive indices to OpenCL...
12:35.44 mdtwenty[m] i think the primitives are all supported, because it works if I render only one region at a time
12:36.21 mdtwenty[m] when i run the same scene 2 times
12:37.17 mdtwenty[m] the order of the regions changes, and the seg_sti of segments in the ansi c code follow those changes, but the seg_sti of segments in opencl seems to be fixed
12:39.37 mdtwenty[m] just confirmed and all the primitives in the scene are supported (the scene only contains sphere and the ehy primitive)
12:42.24 vasc the seg_sti is supposed to be the primitive index in the primitive table
12:42.32 vasc i think
12:42.47 vasc so the primitives get reordered?
12:44.09 vasc oh... right... how about the memory consumption?
12:44.20 vasc we need to have some stats on this.
12:45.11 vasc i don't know if there is a standard way to do this using the BRL-CAD API or if we need to roll our own mem stats code
12:45.23 vasc bbl

13:32.44 mdtwenty[m] I was wondering if the reorder of primitives in the clt_prep function could cause the differences in the seg_stis
13:42.11 vasc order is important yes
13:44.13 vasc if (ordered_prims) {
13:44.13 vasc <PROTECTED>
13:44.13 vasc <PROTECTED>
13:44.13 vasc <PROTECTED>
13:44.13 vasc <PROTECTED>
13:44.14 vasc <PROTECTED>
13:44.15 vasc ordered_primitives[i] = primitives[ordered_prims[i]];
13:44.17 vasc <PROTECTED>
13:44.19 vasc <PROTECTED>
13:44.21 vasc <PROTECTED>
13:44.23 vasc <PROTECTED>
13:44.25 vasc }
13:44.27 vasc this must be wrong
13:44.29 vasc <vasc> ordered_primitives[i] = primitives[ordered_prims[i]];
13:44.32 vasc should probably be
13:45.14 vasc ordered_prims isn't initialized anywhere it's read!
13:45.15 vasc bah
13:45.26 vasc well
13:45.34 vasc because it's a calloc, its all 0s
13:45.38 vasc it still makes no sense
13:46.04 vasc oh
13:46.12 vasc its ordered_prims not ordered_primitives
13:46.15 vasc nice names...
13:46.54 vasc forgot about that. the bvh construction algorithm reorders the primitives list.
13:50.17 vasc i suppose the code is ok
13:50.54 vasc BUT
13:50.54 vasc the thing is...
13:50.54 vasc if we reorder this, then we need to store the new order someplace
13:50.57 vasc because the regions need to be in proper order
13:51.54 vasc the bvh algorithm reorder the primitives so they become ordered in spatial order and thus accesses become more memory coherent
13:53.10 mdtwenty[m] hmm
13:53.44 mdtwenty[m] maybe we could reorder the regions accordingly somehow?
13:54.31 vasc yes we need to i guess.
13:55.20 vasc the order is in that ordered_prims[] array in prep.c
13:55.30 vasc it says the new order.
13:58.45 vasc we need to move the OpenCL regions prep code from primitive_util.c to prep.c
13:59.53 vasc hm
14:00.28 vasc if that code was wrong the material colors should be wrong as well no?
14:00.39 vasc are they?
14:01.18 vasc i think operators.g uses different colors for the different primitives
14:01.40 mdtwenty[m] checking
14:02.34 vasc so perhaps the seg_ids aren't "wrong" it's just that the same primitives have a different id because of the reorder.
14:02.44 vasc unless you actually need the id to be the same for some reason...
14:05.29 mdtwenty[m] i don't think the id needs to be the same, it only has to match with the ids in the boolean trees
14:07.23 mdtwenty[m] and yes, the material colors are also incorrect
14:07.24 vasc hm
14:09.10 vasc well it needs to be checked.
14:10.25 vasc there's an easy way to test i think
14:10.55 vasc like, run clt_prep regardless if we render with OpenCL or ANSI C
14:11.04 vasc that should reorder the primitives
14:11.12 vasc for both codes
14:11.26 *** join/#brlcad Caterpillar (~caterpill@unaffiliated/caterpillar)
14:11.52 vasc and the ids should then be the samne
14:11.53 vasc same
14:15.17 vasc clt_prep is called in src/rt/do.c
14:19.14 vasc just remove the #ifdef USE_OPENCL and #endif on do_prep() in src/rt/do.c to make it always build the bvh and reorder regardless if its in opencl render mode or not.
14:19.35 vasc that way the ids should be the same on both ANSI C and OpenCL so we can test
14:19.39 vasc if that's the problem
14:21.50 mdtwenty[m] hm it produces the same results
14:22.13 mdtwenty[m] shouldn't also remove the if (opencl_mode) condition? or it is always true?
14:22.35 vasc yeah remove that too
14:23.18 vasc so the prep always runs
14:26.10 mdtwenty[m] hm i get an error ("failed to create OpenCL boolean regions buffer")
14:26.18 vasc ...
14:26.50 vasc it's because of the clt_db_store... bah
14:27.47 vasc still why...
14:28.14 vasc oh right doh
14:28.20 vasc OpenCL isn't initialized.
14:28.30 vasc so of course the operations fail.
14:28.46 vasc initialize opencl
14:30.14 vasc rt/main.c
14:30.50 vasc uncomment those #ifdef USE_OPENCL and the if() and the close in rt/main.c just like you did in do.c
14:31.02 vasc so clt_init() is always executed
14:31.10 vasc i hope that's enough...
14:32.23 vasc and that there isn't any voodoo left.

14:34.35 mdtwenty[m] ok it worked and the resulting image is fine
14:35.24 vasc great. now the question is are the ids the same or not.
14:35.32 vasc in both opencl and ansi c
14:36.12 vasc the seg_ids
14:38.05 mdtwenty[m] (when i said the resulting image is fine i meant the image produced by the ansi c, the opencl resulting image is not)
14:38.23 vasc oh ok. but are the seg_ids the same now or not?
14:39.24 vasc you said they weren't in the blog right?
14:40.16 mdtwenty[m] they are still different
14:40.25 vasc hm
14:40.31 vasc that's strange
14:40.37 vasc both should be reordered now...
14:40.50 vasc oh right
14:40.55 vasc THE SOLIDS ARRAY
14:40.55 vasc bah
14:42.13 vasc its never gonna work this way
14:42.37 vasc time to cludge it i guess
14:43.08 vasc we reorder the rtip->rti_Solids
14:43.14 vasc >:-)
14:43.35 vasc in clt_prep
14:43.45 vasc <PROTECTED>
14:43.45 vasc ordered_primitives[i] = primitives[ordered_prims[i]];
14:43.45 vasc <PROTECTED>
14:43.51 vasc add this inside the loop above:
14:44.23 vasc uh...
14:44.32 vasc right
14:45.07 vasc <PROTECTED>
14:45.23 vasc it should work in that operators.g scene anyway.
14:45.40 vasc but it's a really evil kludge...
14:46.03 vasc that should reorder the ANSI C solids list to be the same order
14:46.20 vasc clt_prep is in prep.c
14:47.33 vasc now the question is...
14:47.34 vasc uh
14:47.45 vasc are the regions created before the init or not...
14:47.46 vasc well
14:48.05 vasc maybe its better just to keep the ordered_prims[] array around and translate the ids so we can check...
14:48.41 vasc instead of doing all this crap
14:49.08 vasc thing is we need a reverse translation
14:51.38 mdtwenty[m] hm, so if we know that the primitive with id 1 when ordered will get the id 4 for example, couln't we go on the boolean tree and update the 1's for 4's and so on?
14:52.15 vasc thing is, how is the boolean tree built
14:52.20 vasc and are those ids wrong or not
14:58.02 vasc they probably are
14:58.24 vasc so hmm
14:59.29 vasc like i said
14:59.47 vasc we need to build the regions inside clt_prep, instead of in primitive_util.c
14:59.57 vasc coz clt_prep knows the order
15:00.46 vasc wait
15:00.51 vasc the order is stored in ids[] too
15:02.09 vasc riight
15:02.14 vasc so we use that to do the translation
15:03.13 vasc ah, but this one is the inverse mapping
15:04.05 vasc we wanna know the new id with the old id in hand
15:04.43 vasc well it might work
15:05.42 vasc nope
15:06.05 vasc not without a search
15:06.12 vasc anyway
15:06.32 vasc make sure you convert the ids in the tree to the new order before you send them to the opencl side
15:08.50 vasc when it's an UOP for a solid, .st_bit is supposed to be the solid id
15:08.52 vasc but because of the bvh its out of order
15:08.55 vasc so that's your problem
15:09.09 vasc the rtree can't be send to the opencl side without reordering it
15:09.19 vasc the bits in st_bit
15:10.30 vasc but you need either the inverse mapping for that, or when you do a new rtree construction algorithm specific for the opencl side.
15:11.30 mdtwenty[m] i will do that
15:12.22 vasc this is a bit of a nuisance.
15:13.48 vasc the easiest way is to check where that solid id is in the solids array, but that requires a search
15:14.23 vasc that's O(n^2) with the easiest algorithm, which kinda sucks.
15:14.47 Stragus hugs and cuddles hash tables
15:15.17 vasc nah, there's an easier way i think
15:15.38 vasc like before you reorder the solids array, you store the next position for each element
15:15.45 vasc the new position
15:15.49 vasc that's like O(n)
15:16.01 vasc and the lookup is O(1)
15:16.14 Stragus Eh, all right. I wasn't quite following the context or problem
15:17.06 vasc mdtwenty[m], make sure you revert those changes to rt/do.c and rt/main.c etc
15:17.36 vasc sorry about that
15:22.07 vasc like you do a loop where map[ordered_prims[i]] = i;
15:22.20 vasc that generates the inverse mapping in linear time
15:22.54 vasc like, if we ordered_prims is 2,1,0
15:23.24 vasc hm
15:24.33 vasc no that's the same thing

18:57.53 vasc right. the chinese quantum whatever.
18:58.10 vasc but i think its only good for data.
18:59.05 vasc they also claimed to have quantum radar some months ago.
18:59.05 vasc whatever that's supposed to be.
19:06.34 vasc the problem with the map loop that i said before is that sometimes primitives are removed from the solids list
19:06.42 vasc so the list has holes
19:06.52 vasc so the ids might not map like that.

15:19.24 vasc hello mdtwenty[m]
15:20.28 mdtwenty[m] hello
15:20.38 mdtwenty[m] sorry yesterday, was having lunch
15:21.02 vasc no problem. i had to leave early in the afternoon as well.
15:21.14 vasc how's the code going?
15:23.24 mdtwenty[m] hm so after translating the bits of the boolean tree i could get the operators scene to work for some views (i found later that some views have a strange behaviour)
15:23.53 vasc so what's the difference between translating the bits and not translating the bits, in terms of visual output?
15:23.59 Notify 03BRL-CAD Wiki:95.18.89.88 * 10100 /wiki/User:Mariomeissner/logs:
15:25.27 mdtwenty[m] if i dont translate the bits, the render always differ, because the boolean trees changes and so do the partitions evaluated
15:26.03 mdtwenty[m] but when i translate the tree the output is fixed
15:26.26 vasc ok
15:26.48 vasc well
15:27.22 vasc i think it's like this. we clean up the code a bit and try to put it into the SVN branch.
15:27.37 vasc there's still some bugs, but i think it's close to optimal.
15:28.02 vasc at least as far as an alpha release can go
15:28.51 vasc from now on, make your code against the opencl branch: https://svn.code.sf.net/p/brlcad/code/brlcad/branches/opencl/src/librt/
15:28.52 gcibot [ p/brlcad/code - Revision 69941: /brlcad/branches/opencl/src/librt ]
15:29.09 mdtwenty[m] yes, i think so!
15:29.17 vasc make a patch, download that, and make a patch against that version
15:29.27 vasc then i'll review it and we'll apply it
15:29.55 vasc this isn't good enough to go in the trunk yet, but i think we need to keep it stored someplace.
15:30.50 *** join/#brlcad merzo (~merzo@136-3-133-95.pool.ukrtel.net)
15:31.12 mdtwenty[m] will do that!
15:31.31 mdtwenty[m] this is the one example of a bug that is happening
15:32.03 mdtwenty[m] uploaded an image: operators.png (138KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/QRtTVgTwEFAWVKOtedoSguQa>
15:32.03 mdtwenty[m] is some views this "holes" happend
15:32.53 vasc that's really weird.
15:33.27 mdtwenty[m] hm it is not that weird with the wireframe
15:33.31 mdtwenty[m] sec
15:34.05 vasc it's like it's evaluating the tree wrong?
15:34.28 vasc the segments seem ok
15:35.24 mdtwenty[m] uploaded an image: operators_wire.png (192KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/QEPwQVVQWceIapNElAnxOMfn>
15:35.37 mdtwenty[m] it seems like the geometry in yellow is interfering
15:35.57 vasc yeah that helps. like thought, it's like its evaluating the boolean csg wrong but the segments seem to be ok.
15:36.09 mdtwenty[m] this can be an error with the regiontable, or the lack of support for overlapping partitions
15:36.22 mdtwenty[m] i think, not sure yet
15:37.13 vasc well once we get this into svn, we need to fix that issue with the region's primitive id translation
15:37.41 vasc and we need to get some kind of translator so that we can compare the output of the intermediate steps in the opencl and ansi c code.
15:37.59 vasc or just fix the bugs.
15:38.38 vasc lack of support for overlapping partitions?
15:38.58 vasc in which part of the code is that supposed to be in?
15:39.36 mdtwenty[m] is a part of the rt_boolfinal function
15:39.39 vasc oh
15:39.53 vasc but the boolweave is feature complete right?
15:40.51 mdtwenty[m] i didn't implemented it yet because was trying to understand the FASTGEN regions
15:41.18 vasc ah. THAT
15:41.23 mdtwenty[m] yeah i think booleweave is complete now
15:41.32 vasc ignore those. in fact just strip the FASTGEN code from the opencl port.
15:42.15 vasc FASTGEN is like legacy support for an older solid modelling system that the US military used from what I understand.
15:42.35 vasc fact is, i didn't even port the FASTGEN primitives.
15:42.48 vasc so it's kinda pointless to implement the FASTGEN csg code.
15:43.41 vasc if for whatever reason it's necessary to implement FASTGEN someday, then we'll think about it.
15:43.55 mdtwenty[m] hm i see. i was not sure if it was important for the ocl code so thanks for claryfying
15:44.24 vasc BRL-CAD has a FASTGEN import module that imports FASTGEN scenes.
15:44.44 vasc the database format for FASTGEN is kinda weird. it has like special primitives and the way the rendering works is also different.
15:46.15 Notify 03BRL-CAD Wiki:Mariomeissner * 10101 /wiki/User:Mariomeissner/logs:
15:46.32 mdtwenty[m] ok
15:46.55 mdtwenty[m] the other day you said something about storing the results of the boolean evaluation in the struct partition
15:47.48 mdtwenty[m] which i currently do
15:48.18 vasc that should probably be kept in a separate data structure
15:48.36 vasc or we should just make the evaluation work faster so that we don't need to cache that in the first place.
15:50.20 *** join/#brlcad skat00sh (uid103741@gateway/web/irccloud.com/x-owitdxmtukjpgbew)
15:51.35 vasc btw the opencl branch in svn already has the boolean tree code.
15:51.47 vasc so you might get merge conflicts because of that.
15:52.02 vasc you'll have to manually apply the patch.
15:53.11 mdtwenty[m] ok thanks for the heads up
15:53.19 mdtwenty[m] will apply it mannually
16:01.33 mdtwenty[m] i will just remove some debug code from the code and will clean it a bit before submiting the patch to the opencl branch
16:02.23 mdtwenty[m] or should i finish rt_boolfinal first? (overlapping partitions)
16:03.37 vasc well
16:04.09 vasc just show me what you have
16:04.29 vasc there should be some debug and log code in there
16:05.52 vasc some of those should be kept i think
16:15.01 mdtwenty[m] yeah probably is good idea to have some debug code in there
16:15.12 mdtwenty[m] posted a file: rt_bool_final.patch (62KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/uomSumphCREJqrcPmarkhjYX>
16:15.19 mdtwenty[m] this is what i got right now
16:15.50 mdtwenty[m] i m already using a dynamic bitvector for the regiontable
16:16.30 vasc yeah but that's against trunk/ not branches/opencl right?
16:16.51 mdtwenty[m] ah yes it is not against the opencl branch yet
16:17.44 mdtwenty[m] i just checked out the opencl branch from the svn, so if you give me some time i can apply the patch manually and sent it to you
16:18.16 vasc there also seems to be some noise
16:18.28 vasc like in the rendering function rt.cl
16:18.44 vasc because you indented some code differently some things are reported as changed even though the code is the same
16:20.43 mdtwenty[m] oh i see.. will fix that
16:30.08 vasc this code is missing in opencl boolweave:
16:30.16 vasc if (segp->seg_stp->st_aradius < INFINITY &&
16:30.16 vasc <PROTECTED>
16:30.16 vasc <PROTECTED>
16:30.18 vasc ...
16:32.01 vasc also this is kinda strange:
16:32.02 vasc <PROTECTED>
16:32.32 vasc <PROTECTED>
16:33.33 vasc is that the circular 'pointer' in the head and tail of the list again?
16:33.55 vasc shouldn't it be, like, 'j = head_pp' or whatever?
16:37.33 mdtwenty[m] hum yes, j = head_pp is equivalent, but shorter
16:38.00 mdtwenty[m] i already have it that way in rt_boolfinal
16:39.15 vasc also name those functions boolweave and boolfinal
16:39.22 vasc don't use different names than the ANSI C names
16:39.35 vasc it makes it harder to understand which is which
16:40.03 vasc and yeah eval_partitions/rt_boolfinal needs to be cleaned up
16:40.13 vasc and some things need to be refactored.
16:43.45 vasc yeah we'll need an overlap handler...
16:44.04 vasc ah well.
16:44.13 vasc fix the things i said and make a patch against branches/opencl
16:44.33 vasc i'll then apply the boolweave code, but the boolfinal code still needs some work
16:45.35 mdtwenty[m] sure will do that
17:08.19 Stragus Hrm... perhaps these INFINITY should be replaced with FLT_MAX or DBL_MAX
17:08.39 Stragus Some chips become up to 900 times slower when perfoming a floating point operation where an infinity or NaN is involved
17:08.51 Stragus (including comparisons)
17:10.01 vasc well, we want bug for bug compatibility with the ANSI C code though.
17:10.27 Stragus Right. That comment was mostly for the CPU side of things
17:10.31 vasc i mean if we wanted speed we wouldn't be using doubles on a GPU in the first place.
17:10.38 Stragus Eh, indeed
17:11.10 vasc still its a reasonable argument. considering we have some defines for doubles as floats an an option.
17:11.13 Stragus But even modern CPU Intel chips are 200-300 times slower with infinities. AMD doesn't care about inf/NaN
17:11.47 vasc so you say #undef INFINITY and #define INFINITY DBL_MAX?
17:12.30 Stragus Basically yes, though I would personally prefer some custom foo_MAX macro rather than replacing INFINITY
17:13.39 vasc in opencl that would be MAXFLOAT it seems
17:14.09 vasc ah no
17:14.11 vasc that's SP
17:14.15 Stragus nods
17:15.04 vasc doesn't the compiler do those kinds of optimizations you use ffast-math or something?
17:15.09 vasc if you use
17:15.18 Stragus No, that would change the behavior of the code
17:16.28 vasc i think ffast-math disables those checks though
17:16.28 Stragus I'm not currently aware of the performance of Inf/NaN on GPUs, but it's a good idea to avoid these in any case
17:16.45 vasc https://gcc.gnu.org/wiki/FloatingPointMath
17:16.46 gcibot [ FloatingPointMath - GCC Wiki ]
17:17.20 vasc "In addition GCC offers the -ffast-math flag which is a shortcut for several options, presenting the least conforming but fastest math mode. It enables -fno-trapping-math, -funsafe-math-optimizations, -ffinite-math-only, -fno-errno-math, -fno-signaling-nans, -fno-rounding-math, -fcx-limited-range and -fno-signed-zeros."
17:17.20 vasc -ffinite-math-only
17:17.56 Stragus Hrm -ffinite-math-only, indeed
17:18.19 Stragus Though I'm aware of a performance gain when I removed infinity checks on code that was using ffast-math several years ago
17:19.16 Stragus And assuming you do want to check for overflows, a check against DBL_MAX is still a good idea, eh
17:19.19 vasc well it wouldn't be the first time a compiler wouldn't behave like it's supposed to.
17:21.53 mdtwenty[m] hm, should i use DBL_MAX then?
17:22.26 vasc keep it as is for now
17:22.26 vasc we don't want even more weird behavior right now.
17:22.26 vasc leave the optimizations for later.
17:22.38 vasc just make a note for it.
17:22.54 mdtwenty[m] ok :)
17:42.30 vasc given the amount of things which need to be optimized...
17:42.45 vasc we'll go for algorithmic improvements first.
17:46.54 vasc there's lots of O(N^2) things, spurious memory usage and access and things like that which need to be fixed first
17:48.00 vasc besides i'm not sure the compiler doesn't do that in the first place
17:48.21 vasc without looking at the assembly code output i wouldn't make changes like that.
17:51.12 Stragus Ah right... but I think perhaps that should all have been done before porting to GPUs?
17:52.47 Stragus Optimization and debugging on GPUs is more troublesome, it's easier to settle the algorithm and code on CPUs first
17:52.47 Stragus And I'm not entirely convinced about GPU performance considering the need for double precision, compared to CPU AVX2
17:53.18 vasc well. this is OpenCL. it runs on the CPU as well. in fact mdtwenty[m] has been running and testing it there.
17:54.03 vasc and i did prototype the boolean evaluator in ANSI C before mdtwenty[m] ported it over.
17:54.30 vasc the boolean weaving code is also a relatively straightfoward port.
17:54.38 Stragus All right then
17:54.52 vasc the boolfinal might not be, because i suspect the current way of doing it isn't optimal. but mdtwenty[m]'s still working on that.
17:55.33 vasc also it's not that GPUs are slow at double's. it's that NVIDIA cripples the budget GPUs.
17:56.43 vasc have you looked at the DP FLOPS of the V100?
17:57.08 Stragus Sure sure, it's all right in the $3k GPUs
17:57.09 vasc 7014 GFLOPS on the PCIe V100
17:57.16 vasc DP GFLOPS
17:58.10 Stragus On consumer GPUs, I have had better performance using dual-float math instead of doubles (for similar accuracy)
17:58.16 vasc how many GFLOPS do those Skylake server processors or the AMD Epyc have?
17:58.52 vasc it says in this article

18:03.21 Stragus Screw you Intel :), I'm waiting for dual-socket Epyc motherboards to upgrade my desktop
18:04.06 vasc https://en.wikichip.org/wiki/intel/xeon_bronze
18:04.07 gcibot [ Xeon Bronze - Intel - WikiChip ]
18:04.09 vasc those are cheaper.
18:04.47 vasc also half the clockspeed.
18:04.47 Stragus And I know profesional grade GPUs are better at double precision. But on a typical desktop machine with a gaming GPU, it's not so clear
18:05.06 vasc yeah, it's a good question, what's better on a typical desktop.
18:05.29 vasc which is one reason why we went for opencl and not cuda, despite all the extra work in it.
18:05.35 vasc because of the crap libraries.
18:06.30 Stragus The best double-precision-like performance I had on gaming GPUs was a healthy mix of regular floats and dual-floats
18:06.59 Stragus Just in case you could use that, here's my code for double-float arithmetics: http://www.rayforce.net/ddm.h
18:09.21 vasc what's the license?
18:09.54 vasc 0h it uses sse
18:09.54 Stragus "Do whatever you want with it", I should put a header
18:09.54 Stragus No no, that was just some optional optimization attempt
18:10.25 Stragus The double-double math is also useful when you need higher accuracy than double but with decent performance
18:10.48 vasc ok i'll keep this under my hat
18:10.51 vasc :-)
18:10.56 vasc now really bbl
18:11.02 Stragus :) Okay

23:11.15 brlcad super relevant paper .. I love the architecture simplicity: http://tabellion.org/et/paper17/MoonRay.pdf
23:11.57 brlcad vectorized a production tracer just like rt, from DFT to BFT
23:17.01 Stragus When I tried making coherent ray queues on GPUs, to trace coherent bundles, I hit a wall on global memory bandwidth. And the on-chip shared memory wasn't large enough to store much
23:17.22 Stragus Perhaps the L2 cache of CPUs can manage something better
23:18.12 brlcad paper utilized 4-way simd, cpu
23:18.32 brlcad well, n-way, but the intel box they were using was 4-way
23:19.08 Stragus Right. And cache misses are far more catastrophical on CPUs than GPUs
23:19.09 brlcad it was a production rendering system, so for them, most of the time was in the shading/texturing phase -- there is where they got the largest gains
23:19.57 Stragus Ah yes, of course! So the performance bottleneck wasn't coherent tracing in the scene, it was the texture memory access in the ray hit callback
23:20.24 Stragus It makes sense then. Because my experiments with coherent tracing were inconclusive regarding the performance of ray tracing itself
23:22.58 Stragus ("coherent tracing" as in continuously rebuilding coherent bundles from incoherent rays, not primary coherent rays)
23:23.03 brlcad yeah, their engine used embree under the hood for intersection
23:24.12 Stragus Your bullet rays tend to be highly coherent anyway. :) For stuff like radio wave propagation, not so much
23:27.52 brlcad just heard a fantastic talk yesterday focused on incoherent rays, completely different approach
23:29.06 Stragus Ah? Different from buffering them and making coherent bundles?
23:30.15 brlcad yes, because he wanted performance all the way down to single rays too (actually the focus)
23:30.48 brlcad making a single ray trace as fast as possible
23:31.26 Stragus When I did ambient occlusion or global illumination, I just _made_ the secondary rays coherent. Neighbor primary rays generate secondary rays with coherent vectors, with an appropriate probability "weight"
23:31.41 Stragus So what's different about that?
23:32.18 brlcad because with a single ray, there's no other rays to make it (more) coherent
23:32.49 brlcad except for making it internally do things you might not think to otherwise
23:33.51 Stragus Like testing bundles of 8 triangles in paralle, instead of 8 rays against one triangle?
23:34.06 Stragus One ray against bundles of 8 triangles, that is
23:34.24 brlcad sort of
23:34.53 brlcad more like one ray, bundling the traversal(s), against triangles
23:35.06 brlcad he used compression tricks, simd, and branchless coding
23:35.30 brlcad very nice speedups
23:35.43 Stragus Well, I'm both curious and skeptical
23:36.12 Stragus Testing bundles of 8 triangles is obviously good for incoherent rays (been there, done that). But... compression?
23:36.35 brlcad compression of the traversal
23:36.36 Stragus Besides shifted 16 bits traversal offsets between nodes of the acceleration structure (done that too)
23:36.41 brlcad I'll see if I can get the presentation
23:37.25 Stragus I order the content of my raytracing graphs so that you can jump between sectors and nodes with a 16 bits << 4 offset
23:37.35 Stragus I guess that counts as compression
23:39.29 brlcad so instead of jumping between sectors, I think it would be kind of like evaluating multiple sectors simultaneously
23:39.49 brlcad no way I can describe it with justice, still haven't read the paper, but the talk was very compelling, interesting
23:40.51 brlcad branch-free traversal was a big point, no conditionals so the ray evaluates everything along the path (faster than evaluating and terminating conditionally)
23:42.17 Stragus Hrm. You end up fetching a _lot_ of pointless memory if the ray keeps going when it could just stop
23:43.03 Stragus Unless you mean branchless testing of the triangles from a single sector. That's all right, it's already pulled into cache
23:43.33 brlcad no, branchless traversal (don't recall if triangle testing was also branchless)
23:44.07 Stragus I am totally unconvinced by that
23:44.42 Stragus If I'm looking at a wall, I want my rays to stop there. Not continue to fetch geometry from the street outside
23:45.35 brlcad that was the trick, though -- I don't think he fetched the geometry unnecessarily, at least not beyond a "traversal bundle" which might have been a bit past
23:46.11 Stragus Sounds like branchless testing of all triangles into a sector, or something similar
23:47.57 Stragus I remember trying branchless triangle testing many years ago... It was slower everywhere, except on the Pentium 4 due their absurd branch misprediction penalty
23:49.05 Stragus Although if you are testing bundles of 8 triangles for a ray, rather than 8 rays for a triangle, then you definitely want branchless
23:54.29 Stragus It is an intereting thought to have a whole CUDA warp test 32 triangles for a single ray. The graph evaluation cost function would have to be adjusted (fatter sectors, less sectors, lower memory consumption)
23:55.16 *** join/#brlcad djkonro (~djkonro@129.0.42.239)
23:55.45 Stragus Sounds like a waste of processing potential during traversal though (not geometry intersection)

00:00.23 brlcad the myopic focus on making just one ray fast(er) was refreshing
00:00.54 brlcad talk included a memory footprint analysis
00:03.43 Stragus Hrm yes... Test single ray for intersection against 8||32 sectors (overlapping in space), for each intersector sector (sorted first?): test intersection against groups of 8||32 triangles
00:04.29 Stragus With sectors overlapping in space so that each triangle is unique to one sector, for coherent memory loads
00:04.39 Stragus If I had to write a new raytracer for some reason, I would try that
00:05.05 Stragus for each intersected* sector (and definitely sorted)
00:07.11 brlcad starting to sound more like what he presented
00:07.42 brlcad he's going to get me his presentation, should have it later

14:23.15 vasc about bool_eval()...
14:23.35 vasc did you see patch i posted on the patches tracker?
14:23.51 vasc <PROTECTED>
14:24.22 mdtwenty[m] I have commited the changes already in the opencl branch
14:24.58 vasc https://sourceforge.net/p/brlcad/patches/473/
14:24.58 i5o [ BRL-CAD / Patches / #473 Eliminate gotos from bool_eval() ]
14:25.34 vasc apply this patch to brlcad trunk/ and try running your tests on that to see what's the performance difference vs the old code.
14:25.59 vasc if that's fast enough, then we can work on a simplified prototype in ANSI C to port to OpenCL later.
14:26.22 vasc with a linearized binary tree in an array, instead of storing the expression tree in rpn format.
14:26.32 vasc so the tree would be in infix notation.
14:27.08 vasc it shouldn't even use more memory if we do it right.
14:27.43 mdtwenty[m] hm okay I will apply the patch and test it
14:28.03 vasc ok. i'll try to advance the pseudocode for the solution to speed this up.
14:28.58 mdtwenty[m] yeah I think most of the bugs with the csg code are fixed now
14:31.19 mdtwenty[m] the images match the results from the ANSI C code, although some scenes have missing geometry from the primitives that are not supported yet (goliath.g is one example of this, where some pipes are missing)
14:31.33 vasc i'm gonna need to know the first material in a solid so i can shade the primitives properly in the one-hit shader though.
14:31.45 vasc yeah pipe is used quite often.
14:32.15 vasc but the code is kinda more complicated than that of regular primitive. that's why i didn't ask you to work on it.
14:32.28 vasc pipe is a composite primitive.
14:32.44 vasc its a list of segments of things.
14:33.37 vasc it would distract from the purpose of getting the csg working.
14:33.51 vasc let's see...
14:34.16 vasc i need some data structure.
14:34.17 mdtwenty[m] hm yes I remember you saying that porting that primitive would take some work
14:35.21 vasc in case you're curious you can look at src/librt/primitives/pipe/pipe_shot.c or something like that.
14:36.04 vasc https://svn.code.sf.net/p/brlcad/code/brlcad/trunk/src/librt/primitives/pipe/pipe.c
14:36.53 vasc if you do a 'wc -l' to get a linecount on the pipe.c file vs, say, ehy.c you would see that's it's a lot more complex.
14:37.10 vasc anyway...
14:38.07 vasc implementing bool_eval() is easier than that.
14:38.15 vasc seriously.
14:40.36 mdtwenty[m] hm yes lets first optimize the code and then I can look into porting some more primitives into OpenCL :)
14:42.58 vasc nah.
14:43.05 vasc we want to optimize this to the max.
14:43.12 vasc screw the primitives.
14:43.22 vasc we only have one month.
14:44.01 mdtwenty[m] ah yes, I meant eventually after the gsoc period
14:44.16 vasc maybe next year. :-)
14:45.01 vasc and mind you, implementing pipe would be a breeze compared to the other main ticket item left to do... the brep intersector.
14:45.44 vasc gah.
14:45.49 vasc that's another gsoc or two.
14:46.36 vasc if we get all that working, i think this will have a more complete GPU intersector than ANYTHING ELSE in the market right now.
14:47.01 vasc if it happens.
14:47.16 vasc anyway...
14:51.27 vasc we'll use something like this bin tree representation
14:51.32 vasc https://github.com/mmp/pbrt-v2/blob/master/src/core/kdtree.h
14:51.33 i5o [ pbrt-v2/kdtree.h at master · mmp/pbrt-v2 · GitHub ]
14:52.13 vasc that's for a spatial kd-tree, but the data structure is more or less the same a bintree. in fact ours is simpler because we don't need to store as much data on the nodes.
14:59.31 mdtwenty[m] okay, IIRC the idea is to store the jumps in the data structure, along with the boolean tree information?
15:00.14 vasc yes.
15:00.23 vasc this is the data structure the code uses now:

15:02.07 vasc ta-da.
15:02.09 vasc a linearized array binary tree.
15:02.24 vasc where nodes are either branches with binary ops (has_lchild = 1) or leafs with solids (has_lchild = 0)
15:03.10 vasc the current code is a horrible, horrible waste of memory and has lotsa pointer chasing.
15:03.19 vasc we're gonna fix that.
15:04.06 Stragus Having the whole acceleration structure as a big linear blob of memory is good, and you can use relative offsets to jump around
15:05.06 Stragus 16 or 32 bits with a << 4 is pretty good. 32 bits is easier, 16 bits involves a complicated shuffling/ordering solution
15:05.08 vasc right. when it's a branch, left child is always at current_offset+1, and the right child is that current_offset+tree.rchild. or was that tree.rchild. i don't remember.
15:05.24 Stragus Ah, or that
15:06.09 vasc so each tree node should fit into 32-bits.
15:06.18 vasc 4 bytes.
15:06.44 vasc instead of... 4*2 + 8*3 bytes.
15:06.56 vasc 32
15:07.12 vasc 8x smaller.
15:07.22 vasc and not as much pointer chasing.
15:07.29 vasc so
15:07.42 vasc that's the whole idea.
15:08.09 vasc now the small detail of getting it to work.
15:08.29 vasc "small detail"
15:08.52 Stragus *nods* My raytracers always used a linear blob of memory for each graph. Another wonderful detail is that you can save the blob to disk and use "as is", you can use on both CPU and GPU directly, it just works
15:09.24 vasc yes. we'll use a simple recursive function the CPU to linearize this tree, and then we'll just copy that to the GPU.
15:10.33 Stragus Linearizing on CPU would be a good idea too
15:10.46 Stragus (and it makes things easier, same data structure everywhere)
15:18.59 vasc meh... the code for the kd-tree in pbrt is too complicated. i think I also saw this in Wald's thesis someplace.
15:21.47 vasc I think I first read about this in Gordon Stoll's SIGGRAPH presentation.
15:22.48 vasc hmmm...
15:23.09 vasc i probably has some of my own code someplace with this.
15:23.11 vasc have
15:24.00 mdtwenty[m] I've just tested your patch (https://sourceforge.net/p/brlcad/patches/473/) and it seems to match the current times with the version on the trunk
15:24.01 i5o [ A 404 Error has Occurred ]
15:24.13 vasc ok, but what about the times?
15:24.18 vasc oh
15:24.21 vasc great.
15:24.34 vasc so we got ourselves an algorithm without gotos.
15:24.36 mdtwenty[m] goliath is the same (0.33 vs 0.33)
15:24.47 vasc which can't be used in OpenCL.
15:25.21 vasc now we need an algorithm without gotos, wasted memory, needless pointer chasing, and no dynamic memory.
15:25.32 mdtwenty[m] havoc (0.62 new version vs 0.63 in the trunk)
15:25.33 vasc that takes care of the first problem.
15:25.35 mdtwenty[m] so no big difference
15:25.47 vasc yeah, that could just be measuring error.
15:25.53 vasc should be anyway.
15:26.33 vasc you wanna code the ANSI C prototype?
15:27.09 mdtwenty[m] yeah I can give it a try!
15:27.13 vasc we basically need to code a tree builder and a tree traverser.
15:31.06 vasc i was trying to find some of my old code so you could use that as a base.
15:33.26 vasc ah well.
15:33.46 vasc dunno if it survived my HD crash 3 years ago.
15:37.24 vasc meh. finding mostly code snippets of bin trees accessed with shifts.
15:37.37 vasc but that means it has to be a balanced bin tree, or it wastes a lot of memory so...
15:38.52 vasc anyway
15:41.12 vasc https://pastebin.com/R4SZpDMD
15:41.13 i5o [ [C] #define OP_UNION 0 /**< @brief Binary: L union R */ #define OP_INTERS - Pastebin.com ]
15:41.15 vasc this should help
15:41.42 vasc i don't want you to waste a lot of time reinventing things that have already been invented.
15:41.53 vasc so we can use the remaining time to actually invent new stuff.
15:41.57 vasc :-)
15:43.49 vasc start by building the tree builder, that converts a trunk/ union tree into that array of uints with the layout i mentioned before, and a function to print it to examine the output.
15:44.38 vasc you can use the KdTree() constructor and recursiveBuild() function I put in the pastebin from PBRT as a reference.
15:45.04 vasc but you'll need to use shifts and things like that to store things in 32-bits.
15:45.19 vasc because OpenCL does not have support for bitfields in structs either.
15:45.23 vasc gotta love OpenCL.
15:46.08 Stragus Managing the bits yourself sometimes allows producing better code than with bitfields anyway
15:46.18 vasc https://stackoverflow.com/questions/9033947/why-are-bitfields-not-allowed-in-opencl
15:46.19 i5o [ bit fields - Why are bitfields not allowed in OpenCL? - Stack Overflow ]
15:47.14 vasc ah so it's because of endianess? bah.
15:47.29 vasc then what about ints? those would need to be converted too...
15:47.36 vasc scratches his head.
15:48.01 vasc so it's just because of padding it seems.
15:49.18 vasc anyway the idea is the first bit says if its a branch or a leaf. if it's a branch the next 3 bits define the binary OP, and the remaining bits where right child is.
15:49.37 vasc if it's a leaf, then the other 30 bits have the solid id.
15:49.39 vasc that's it.
15:49.49 vasc 31 bits actually
15:50.15 vasc i hope 2G solids are enough.
15:51.22 vasc and like 256 M bool nodes.
15:51.37 vasc if it's not enough we can use 64 bits.
15:53.49 vasc mdtwenty[m], thx for conducting the tests.
15:53.59 vasc i'll look at your code now.
15:54.27 mdtwenty[m] no worries :)
15:54.45 mdtwenty[m] i think I got the idea.. I will start working on this and see what I can get
15:55.40 vasc sure. if your ANSI C prototype code turns out to be faster than the one in trunk/ then we can ask Sean to test it and maybe we'll use it in the main ANSI C path as well.
15:56.10 vasc it might be because the nodes are going to be smaller and the memory accesses more coherent.
15:56.33 vasc although i haven't looked at how the code allocates the nodes yet.
16:00.17 vasc you can use the RPN bool patch I made way back when to see which functions you need to implement to completely replace the existing boolean trees in trunk/.
16:02.04 mdtwenty[m] okay thanks! I'll keep that in mind
16:02.44 vasc but like i said, start with the tree builder and the print function.
16:02.56 vasc to debug.
16:13.22 vasc duh... ok, i see. the existing code has memory pool for tree nodes if the nodes get deleted and reallocated. but fresh nodes are just allocated with posix_memalign() or calloc()...
16:13.33 vasc yeah that should make them memory coherent. not.
16:13.53 vasc well maybe if the malloc implementation is smart. which it usually isn't.
16:15.19 *** join/#brlcad Caterpillar2 (~caterpill@unaffiliated/caterpillar)
16:15.44 vasc yes... the results of changing this code should prove quite interesting.
16:16.23 vasc notice how my code which always evaluates the entire expression actually was either the same speed or faster in the simpler expressions.
16:17.00 mdtwenty[m] i hope so!
16:17.55 mdtwenty[m] one thing that i noticed the other day was that the max rpn tree lenght in the havoc scene was 583 IIRC
16:19.16 vasc yeah that doesn't seem so good.
16:19.31 vasc well you know there are several possible strategies to optimize the tree evaluator.
16:21.47 vasc say a solid is never intersected by any ray. so why evaluate that for every partition or whatever?
16:22.10 vasc it's possible to optimize the tree in runtime or prior to render.
16:22.49 Stragus A linear blob with small offsets rathre than pointers, all packed in memory, will definitely be faster on the CPU
16:23.33 Stragus And you can use something like a 3D space filling curve to sort data so it's spatially close, better filling cache lines. I remember getting a few extra percents from that
16:25.13 vasc yeah none of the buffers are in z-order. that likely has a negative impact.
16:25.39 vasc i also need to reduce the amount of memory used in between stages.
16:26.48 Stragus If you ever want some pretty fast space filling curve code: http://www.rayforce.net/ccspacecurve.c http://www.rayforce.net/ccspacecurve.h
16:27.01 vasc about using SoA vs AoS...
16:28.07 vasc once the code is cleaned up we might try that.
16:28.29 vasc but right now i'm more concerned about thread divergence and poor usage of capacity.
16:28.47 Stragus Yup, that's really something for the final touch
16:28.57 Stragus (I gained 2-3% with that, woohoo)
16:29.39 vasc i had like order of magnitude improvements once because full GPU units weren't being used because of divergence.
16:30.00 vasc that one can really bite.
16:30.42 Stragus Instead of testing 32 rays against a single sector or primitive, have you considered one warp testing one ray against 32 sectors or primitives?
16:30.58 Stragus For highly incoherent rays, that seems like a better idea than trying to make coherent non-diverging bundles
16:31.27 Stragus (replace the 32 with 4 or 8 on CPUs, 64 on AMD, etc.)
16:32.00 vasc well right now the code only does primaries. well it's generic enough to be used with any rays, but those are the only rays the generator generates.
16:32.39 vasc i've had a lot of luck with sorting rays to decrease divergence.
16:33.19 Stragus Really?... Sorting rays either eat through your global memory banwidth, or you can't sort enough in on-chip shared memory
16:33.37 Stragus For me, it was always faster to just trace incoherently than to bother sorting them
16:33.39 vasc in my own engine i actually fudged the RNG for the ambient occlusion rays so that those are more coherent. but don't tell anyone that... :-)
16:33.55 Stragus But that could change if the acceleration structure was designed to test one ray against 32 primitives, instead of the other way around
16:34.06 Stragus Eh, I did the same thing
16:34.12 vasc ahah
16:35.02 vasc well the sorting is useful if you have a fast sort.
16:35.09 vasc did you try using the CUB sort?
16:35.20 Stragus The problem wasn't the fast sort, the problem was the global memory banwdith
16:35.28 vasc oh that?
16:35.33 Stragus I could trace incoherent rays for the same amount of bandwidth as sorting them
16:35.34 vasc you use compress-sort-decompress.
16:36.29 vasc have you read this paper?
16:36.30 vasc http://www.keldysh.ru/pages/cgraph/articles/dep20/publ2010/GPU-RayTracing.pdf
16:36.32 Stragus Assuming rays bouncing everywhere, how do you compress the origin, vector and other contextual information about that ray's purpose?
16:36.51 vasc look at that paper. :-)
16:37.29 Stragus The "compression" is for the sort, sure
16:37.52 Stragus But the write,read,write,read for bundling rays takes a lot of bandwidth
16:39.44 Stragus Considering the typical incoherent ray for me had to touch about ~17 cache lines of 32 bytes...
16:39.51 Stragus (if I remember the metric correctly)
16:40.17 vasc hm
16:40.21 vasc well you know
16:40.37 vasc for my own render pipeline i only use that for incoherent rays.
16:41.19 vasc also i think it's not just a problem of memory coherence but of scheduling as well
16:41.38 vasc like, adjacent rays typically have similar complexity.
16:42.12 Stragus Right, less waste from threads having nothing to do
16:42.43 Stragus Well, like I said, if I had to trace a ton of incoherent rays again, I would just use a different acceleration structure
16:42.52 Stragus Test a single ray against batches of 32 triangles instead
16:46.21 vasc i once read a poster by Yoon. he basically ran all the intersections against simplified geometry (like a convex hull of the geometry) to get an estimate for the hit points.
16:46.34 vasc sorted those in z-order. and then used that to schedule the rays.
16:46.52 vasc it was an out-of-core renderer. so it made even more sense there.
16:47.24 vasc actually he used a simplified mesh, not the convex hull now that i think of it.
16:48.04 vasc the ray against triangles... well.
16:48.14 vasc the thing is... triangles are "fatter" than rays.
16:49.08 Stragus But it's a lot easier to make coherent bundles of 32 triangles than 32 rays ;)
16:49.25 Stragus (assuming global illumination-like incoherent tracing)
16:49.45 vasc 3 vertexes with 3 coordinates of 4 bytes vs 2 vertexes with 3 coordinates.
16:49.53 vasc and that's not even assuming the rays have same origin.
16:50.32 Stragus Rays also need to track contextual information, so you can accumulate back to whatever bounce it came from
16:50.55 vasc sure an id can take care of that.
16:50.58 Stragus (assuming you short and shuffle them)
16:51.02 Stragus sort*
16:51.57 Stragus I don't know, there's a lot of potential for an acceleration structure designed to minimize the count of bundles of 32 triangles being tested (in the global cost function, 1 triangle in a sector has the same cost as 32)
16:53.08 vasc i think i mentioned this in some slides for a class i gave sometime.
16:53.43 vasc i was showing how you can reduce the amount of math ops in the intersections when testing with same ray origin vs same triangles and the like.
16:54.08 vasc i remember that was also less nice for the many triangle approach.
16:54.29 vasc thing is, when the many rays don't have the same origin though, then it changes.
16:55.15 Stragus Right sure, highly coherent rays (including with same origin) is a different problem with a different optimal solution

16:58.59 vasc i remember i analyzed that as i thought it was interesting. and ran some tests. then i gave it up. :-)
16:59.31 vasc oh... what was that other thing...
16:59.38 vasc right.
16:59.53 vasc ray-triangle fan and ray-triangle strip optimized intersection routines.
16:59.59 vasc i was looking at those back then too.
17:00.34 vasc i only found like one decent paper for each one.
17:00.58 vasc it's another way to reduce the bandwidth required for the triangles right?
17:03.10 vasc so i looked at this one: http://gamma.cs.unc.edu/RS/paper_rt07.pdf
17:03.31 vasc but i dunno it seemed kinda lame to me, that you needed to build a BSP
17:04.32 vasc actually an skd-tree but whatever.
17:05.31 vasc it seemed lame to me. to use axis aligned separators.
17:05.44 vasc you already have the planes defined by the triangles or whatever.
17:06.00 vasc so i also ignored that idea.
17:06.09 *** join/#brlcad ``Erik (~erik@pool-100-16-14-17.bltmmd.fios.verizon.net)
17:11.07 vasc there's all sorts of tricks you can ues.
17:11.09 vasc use.
17:11.41 vasc like... you know how they say for primary rays since the origin is always the same, only store the direction? well i only stored the index used to generate the ray.
17:11.58 vasc then i have generator functions for rays. primaries, shadows, ambient occlusion the works.
17:12.03 vasc so the engine was all specialized.
17:13.37 vasc ah whatever. i'm not gonna pick that up again.
17:13.50 vasc i've decided if i ever rewrite it, i'm gonna do everything differently.
17:14.43 vasc so Stragus, are many-triangle intersections in fashion again?
17:17.43 Stragus I have no idea what's in fashion. I almost never read papers, I just have fun ;)
17:18.11 vasc every once in a while something comes out that makes a difference. that's why i read papers.
17:18.29 vasc its usually not a new idea, but, the twist makes the difference.
17:18.39 Stragus And really, I would recommend using a graph rather than a tree
17:18.49 vasc for the geometry right?
17:18.52 Stragus A tree implies a stack, which implies per-thread stores and loads, and that's terrible
17:19.00 Stragus For the space partitioning, yes
17:19.50 vasc isn't that like a tree with ropes like they usually call it? well at least that's how Havran calls it.
17:20.19 Stragus No idea if there's a fancy term for it. But what I use is a graph, sectors connecting to other sectors, there's no tree
17:20.56 vasc then how's the partitioning done? does it still use split planes somehow?
17:21.03 Stragus The idea being to avoid all per-thread memory stores, until you have your intersection point and you need to do something with it
17:21.44 Stragus I use axis-aligned sectors, which can overlap in space, and each facet of a sector can either connect to another sector or a "node" with a splitting plane to decide where to go next
17:22.13 Stragus There are other ways, that's not ideal for the one-ray-against-many-triangles approach
17:22.25 Stragus But just avoid a per-thread stack, no matter how you do it
17:22.39 vasc i've read something similar in papers from the 1980s but i can't say i remember other people working on that. it seemed like a cool idea when i read it.
17:23.30 vasc back then a lot of people were trying to get ray tracing to scale in MPP architectures.
17:24.13 vasc like Transputers or that Intel machine... the one with i860s.
17:24.21 Stragus Tracking a stack in L1 on many-cores no-SIMD chips is no big deal
17:24.35 Stragus But the situation is different with GPUs and modern wide SIMD

17:25.45 vasc maan... they spent a lot of time trying to minimize inter thread communications and ops.
17:26.24 vasc well i dunno if those processors actually had caches.
17:26.26 Stragus Usually, for massively parallel software, you just write code to _avoid_ requiring low latency inter-thread/device communication
17:27.14 Stragus Like for computational fluid dynamics, it's better to compute the same cells redundantely while you receive results from other devices from two time steps ago
17:27.27 vasc ah right. the i860 had caches but early Transputers did not.

18:33.13 vasc mdtwenty[m], the code changes you made to branches/opencl seem to be fine at a glance.
18:40.24 Notify 03BRL-CAD Wiki:Mariomeissner * 10157 /wiki/User:Mariomeissner/logs:
18:40.34 mdtwenty[m] I noticed that some code from my previous patches still had indentation issues, so I fixed that and used it to make my first commit, like a test commit :)
18:41.40 mdtwenty[m] the code to skip unevaluated partitions should be okay, I did some testing and it iterates only over the evaluated partitions, although that didn't make that much of a difference in performance
18:43.36 vasc i remembered now that it might also be possible to reuse the forward_pp in the partitions, so next_evalpp might not be necessary.
18:44.31 vasc in rt_boolfinal.
18:45.11 vasc you just need to cache the partitions[current_index].forw_pp in a variable, which could be named next_index, before writing over the value.
18:45.43 vasc and then in the loop you get the next index from that cached variable instead of from the partition
18:47.39 vasc it should only make a difference in scenes with a lot of depth complexity.
18:47.52 vasc maybe in golliath it makes a difference?
18:49.35 mdtwenty[m] hm it has almost the same, but to be fair I only tested with the view az:35 el:25
18:50.02 mdtwenty[m] front view could have a more noticeable difference
18:51.19 mdtwenty[m] and I think that it is possible to discard the use of next_evalpp now that you mention it
18:52.08 mdtwenty[m] and maybe we dont even need to cache the forw_pp, since I could only update the forw_pp of the last partition evaluated
18:52.13 vasc if we can reuse the foward_pp it would save memory in the partitions.
18:53.25 vasc well you need to save it before you override it, because otherwise when the for (;;) loop iterates the value won't be correct.

18:56.13 vasc no need for the variable even.
18:57.50 mdtwenty[m] yeah :) I will update it
19:04.06 vasc i was also looking at if it was possible to remove the back_pp index by caching the previous index in a variable wherever that is used.
19:04.28 vasc a lot of times algorithms with double-linked lists aren't actually necessary.
19:04.49 mdtwenty[m] IIRC back_pp was only used in 1 condition in boolweave
19:05.22 vasc its used in boolweave and rt_defoverlap
19:07.14 mdtwenty[m] oh yes, right
19:07.50 mdtwenty[m] but I think that could be cached in a variable
19:11.16 vasc i'm not so sure about that..
19:11.24 vasc the boolweave case sure.
19:11.30 vasc but i'm not certain about defoverlap.
19:12.00 vasc because it doesn't iterate the list using the pointers
19:12.03 vasc it uses the ids
19:12.38 vasc hm
19:12.43 vasc yes it might also be possible
19:13.13 vasc by passing it the index to the previous partition via default_multioverlap in boolfinal
19:14.08 vasc so that would shave off like 8 bytes in each partition with these two modifications.
19:14.42 vasc i also have an idea to shave off like half the memory used in the struct hits in the partitions so.
19:15.08 vasc over half actually
19:15.22 vasc so the struct partition should become less than half the size.
19:20.12 vasc it seems like soon enough we'll have a our first generation system.
19:21.03 vasc the only thing which might make things slower is the bitvectors. or not.
19:21.23 vasc it think it will depend on how sparse the bitvectors are.
19:21.51 vasc i suspect they'll be faster on average than if we used lists.
19:22.09 vasc it also makes memory management easier.
19:22.41 vasc oh right, nearly forgot
19:23.10 vasc we're gonna need to make an array with uints, one uint per solid, where the uint has the id of the first region.
19:23.23 vasc so i can shade the materials in single-hit mode properly.
19:23.40 vasc its only necessary in single-hit mode.
19:24.01 vasc you prolly noticed its shading everything white/gray in single-hit mode right now.
19:24.25 vasc and i can't remember anything else.
19:24.38 vasc but there's plenty of optimizations we can do afterwards.
19:24.50 mdtwenty[m] yeah I noticed it, when it wasn't white/gray was every solid it the same color
19:24.52 Notify 03BRL-CAD:n_reed * 70035 brlcad/trunk/src/tclscripts/checker/CMakeLists.txt: Add initial check command test script.Currently runs the check Tcl-command in mged (mged -a nu -c) to checkbasic invocation behavior, and also subtraction behavior on two simpleoverlap cases.No args, but finds check.tcl by CHECKER_DIR environment variable.Doesn't run check.sh. Test databases and overlap directories are writtenout by the
19:24.54 Notify test script itself.
19:24.55 vasc oh, right, i also need to fix the lights.
19:24.56 Notify ...
19:28.23 mdtwenty[m] did you ever tried to render the havoc scene with your workstation GPU? I was curious about what the difference in time would be
19:29.06 vasc it's bad...
19:29.14 vasc there's too many roundtrips.
19:29.32 vasc those can be fixed, but it requires a reduce algorithm.
19:29.42 vasc i think its better not to focus too much on that right now.
19:29.53 vasc we can just focus on the CPU performance.
19:30.11 vasc i can later give you a piece of code with reduce for you to try out the difference.
19:30.30 vasc but the license might not be compatible for wider distribution.
19:30.41 vasc let's see...
19:30.53 vasc yeah i got that here.
19:32.10 vasc ah we don't use the reduce, prolly just scan.
19:32.37 vasc the reduce is a sum, and the scan is prefix sums.
19:32.47 vasc https://en.wikipedia.org/wiki/Prefix_sum
19:32.48 i5o [ Prefix sum - Wikipedia ]
19:34.03 vasc so we can compute the offsets quickly on the GPU side without doing memory transfers.
19:36.00 vasc i.e. this code:
19:36.01 vasc <PROTECTED>
19:36.01 vasc <PROTECTED>
19:36.01 vasc <PROTECTED>
19:36.01 vasc BU_ASSERT((counts[i-1] % 2) == 0);
19:36.01 vasc h[i] = h[i-1] + counts[i-1]/2;/* number of segs is half the number of hits */
19:36.03 vasc if (counts[i-1]/2 > max_depth)
19:36.05 vasc <PROTECTED>
19:36.07 vasc <PROTECTED>
19:36.09 vasc in clt_Frame()
19:36.46 vasc oh... except it does two things it computes the max and it does the prefix sums.
19:36.58 vasc the max_depth is a sort of reduce i guess.
19:40.05 vasc well enough of that
19:40.42 vasc keep me notified of your progress on the ANSI C bool_eval() then mdtwenty[m]. i'll see if can work on the lights this week.
19:41.23 vasc <PROTECTED>
19:41.38 mdtwenty[m] Yeah I will update you as soon as I have some progress
19:41.51 vasc ok see you later!
19:42.08 mdtwenty[m] see you later!

16:32.44 vasc hey mdtwenty[m]
16:33.25 mdtwenty[m] hi!
16:33.57 vasc so let's look at the pbrt code
16:37.15 vasc so you say it doesn't work?
16:38.39 mdtwenty[m] it worked for a small example ( 0 + 1) but when I run it with a bigger example it doens't make much sense
16:39.37 vasc hmm
16:39.42 vasc what's with the loop?
16:39.51 vasc that loop in buildtree() shouldn't be there.
16:40.22 vasc its like, it's a binary tree.
16:40.39 vasc and buildtree() or a node is like add this node and do buildtree() on the descendants.
16:40.40 vasc no loops.
16:40.52 mdtwenty[m] oh
16:41.35 mdtwenty[m] yeah the loop isn't supposed to be there.. its only one instruction inside the pbrt example! I missed that
16:42.44 vasc i dunno why you need rt_flat_tree() either.
16:43.14 vasc hmm...
16:43.40 mdtwenty[m] yes I was about to ask you that
16:44.13 vasc its just like...
16:44.23 vasc you start at the node and build_tree left and right.
16:44.47 vasc the problem is how to know where to store nodes and how to set the rchild index properly.
16:45.38 vasc also
16:45.49 vasc + if (start + 1 == end) {
16:45.49 vasc + rtp[pos].has_lchild = 0;
16:45.49 vasc + rtp[pos].tr_d.tr_l.st_bit = tp[pos].st_bit;
16:45.49 vasc + }
16:45.49 vasc +
16:45.56 vasc it's support to have a return there.
16:46.03 vasc this is the case where it's a leaf.
16:46.09 vasc its just like...
16:46.29 vasc if (leaf) { leafstuff; return; }
16:47.54 vasc + rtp[pos].tr_d.tr_b.uop = tp[pos].uop;
16:47.57 vasc this is before the ifs.
16:48.13 vasc because it happens forall branches (non-leafs)
16:49.20 vasc s/support/supposed/g.
16:49.33 Notify 03BRL-CAD:starseeker * 70036 brlcad/trunk/src/other/libpng/CMakeLists.txt: Not using WDIR after all
16:50.00 mdtwenty[m] hmm okay I will fix these issues with the function! thank you for the help
16:50.31 vasc well
16:50.35 vasc no problem.
16:50.46 vasc just remember. write the code based on the union tree.
16:50.51 vasc and you don't need that flat function.
16:51.06 vasc its just like...
16:51.17 vasc buildtree() if leaf() {} else {}
16:51.40 vasc in the else { buildtree(); /*left*/ buildtree(); /*right*/ }
16:52.25 vasc i only gave that pbrt code so you could look at how it updates the nextfreenode and things like that.
16:52.43 vasc did you get to remove those fields in the partitions?
16:53.06 vasc like the prev index and the next valid partition index?
16:53.28 vasc hm
16:53.34 mdtwenty[m] no, not yet
16:53.45 vasc ok
16:53.46 mdtwenty[m] also
16:54.03 mdtwenty[m] yesterday i run the command that Sean suggested
16:54.19 mdtwenty[m] "mdtwenty[m]: goliath is not really a good test case for patch 473 -- run this instead on before and after: "TIMEFRAME=60 DEVIATION=1 benchmark run""
16:54.53 mdtwenty[m] i run benchmarks for the version in the trunk, the version in the trunk with the patch 473 applied and with the version on the opencl branch
16:55.42 mdtwenty[m] but i am not sure about what number in the benchmark results I should use to compare things
16:55.55 vasc what is the output?
16:56.33 mdtwenty[m] posted a file: run-12576-benchmark_trunk.log (19KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/SrGHIpeiNVUrbivZMlBvpGCG>
16:56.50 mdtwenty[m] this is the output for the version in the trunk
16:57.16 mdtwenty[m] i suppose I should compare with the "total testing time elapsed"?
16:57.39 mdtwenty[m] or with the VGR number?
16:57.42 vasc ok, it loads a bunch of scenes and animates them.
16:59.15 vasc the VGR is some benchmark stat.
17:00.10 vasc you can either compare VGRs or the RTFMs.
17:00.17 vasc the total time ellapsed is also a possibility yes.
17:00.24 mdtwenty[m] posted a file: run-14785-benchmark_opencl.log (19KB) <https://matrix.org/_matrix/media/v1/download/matrix.org/LOESCkSFvUMKSNDYIPAIKzTZ>

17:00.40 mdtwenty[m] those are the other results
17:02.10 vasc uh...
17:03.10 vasc all the VGRs are the same.
17:03.42 vasc ah no
17:04.08 vasc its better with the patch? oh whatever.
17:04.22 vasc that doesn't make a lot of sense.
17:04.34 mdtwenty[m] the version currently in the trunk has a smaller total time elapsed, but also has smaller vgr
17:04.35 vasc it should be exactly the same not faster.
17:05.07 vasc well. i don't know what to say about these numbers since the number of rays traced isn't the same in all benchmark runs.
17:07.14 vasc so you probably need to compare just the performance metric VGR number.
17:07.19 vasc the higher the number the better.
17:07.36 vasc whatever.
17:07.54 vasc you ran the tests with the test scenes and it took the same time with the patch if i remember correctly.
17:08.21 mdtwenty[m] yeah thats correct
17:09.04 vasc it's better that you pass those run results to Sean so he can look at them. perhaps he has more insights.
17:11.09 mdtwenty[m] will do that!
17:11.57 mdtwenty[m] also, can you take a look on the struct tree definition that i wrote? when I run sizeof I got 8 bytes instead of 4 ..
17:12.28 vasc of course you do. what i wrote was pseudo-code.
17:12.33 vasc :-)
17:13.00 vasc you declare an uint, and then a struct.
17:13.32 vasc anyway, that isn't too important right now since we'll have to replace it with shifts later.
17:14.32 vasc so
17:14.35 vasc you just use uints
17:14.59 mdtwenty[m] okay! it was my first time working with bit fields so I wasn't sure if I did things correctle there
17:15.26 vasc and then it's like init_leaf(st_bit)
17:15.34 vasc and init_node(uop, rchild)
17:15.43 vasc and
17:15.47 vasc init_leaf():
17:16.25 vasc <PROTECTED>
17:16.30 vasc init_node():
17:16.51 vasc actually
17:16.54 vasc <PROTECTED>
17:16.58 vasc in init_leaf
17:16.59 vasc and
17:17.27 vasc oh no
17:17.30 vasc it's just
17:17.33 vasc <PROTECTED>
17:17.35 vasc the other is
17:17.54 vasc <PROTECTED>
17:17.56 vasc i think
17:18.12 vasc and then to check if it's a leaf:
17:18.26 vasc is_leaf() : return !(val & 1);
17:18.35 vasc things like that.
17:18.47 vasc if you want i can write it.
17:19.07 vasc it's not that complicated though.
17:20.18 vasc thing is
17:20.27 vasc you need to use the UOP macros i defined
17:20.40 vasc where UOPs are renumbered 0..7 or something
17:20.59 vasc the regular UOP numbers in include/ won't fit in 3 bits.
17:21.23 vasc 2^8 = 8
17:21.31 vasc so only numbers 0..7 will fit.
17:21.39 vasc 2^3
17:21.40 vasc i mean
17:21.42 vasc ..
17:21.45 mdtwenty[m] yeah
17:21.52 mdtwenty[m] sent a long message: mdtwenty[m]_2017-08-03_17:21:52.txt <https://matrix.org/_matrix/media/v1/download/matrix.org/zPUWrgyNDQBBaCTStyAyYZRo>
17:22.03 vasc yes those.
17:22.21 vasc the one for OP_SOLID and OP_NOP are unused.
17:22.27 vasc those are for leafs.
17:22.39 vasc i assume there are no OP_NOP and that all leafs are OP_SOLID
17:23.20 vasc so better assert() that there are no OP_NOP
17:23.21 vasc s
17:24.15 mdtwenty[m] what are exaclty OP_NOPs?
17:25.29 vasc NOP = no-op
17:25.45 vasc it does... nothing
17:26.05 vasc https://en.wikipedia.org/wiki/NOP
17:26.05 i5o [ NOP - Wikipedia ]
17:26.32 vasc i assume it's used in the code for things like...
17:26.48 vasc when it optimizes the tree one of the branches is eliminated.
17:26.56 vasc and that branch is replaced with NOP
17:27.01 vasc and later the NOPs are removed.
17:27.20 vasc but i'm not sure.
17:27.31 mdtwenty[m] ah yes that makes sense
17:29.04 vasc so OP_NOP is an empty volume basically.
17:29.27 vasc and OP_SOLID has the volume of the primitive.

17:31.35 vasc the code for the kdtree in pbrt is more complicated with the splitpos because it needs to partition the tree at variable intervals according to space.
17:31.42 vasc our binary tree doesn't need that.

14:20.37 vasc i do use their bvh builder but i don't remember if that was from pbrtv2 or v3.

14:22.23 vasc i can put hyperplanes inside it.
14:22.25 vasc can't
14:28.39 vasc hopefully we'll get the new bool_eval() ANSI C version working next week.
14:29.08 vasc then it's a matter of porting that to OpenCL.
14:29.56 vasc and we should get back improved performance for bool_eval() on scenes with lots of regions.

15:53.57 mario_ anyone up to help me out with a lil problem I'm facing?
15:58.24 Gud hard to tell if you dont ask your question
15:59.02 mario_ Im trying to run rtweight with a .density file, but it isnt loading it correctly
15:59.20 mario_ I did it in the past on linux without problems but it doesn't seem go work now on windows
16:00.11 mario_ It says: error parsing line 1 of density file. 0 args recognized instead of 3 line buffer reads :  ■1 error parsing line 2 of density file. 18446744073709551615 args recognized instead of 3 ... etc
16:00.54 mario_ the inside of the file is: 1 3.44 plastic
16:17.17 mario_ I did the following:
16:17.38 mario_ -Open terminal in my database-files folder
16:17.57 mario_ -echo "1 3.44 plastic" > .density
16:18.14 mario_ -rtweight box_example.g box.r
16:18.26 mario_ -> The above error displays
16:19.29 mario_ Note that the file IS found, because if I delete it, the error is ".density not found"
16:20.26 mario_ So I'm thinking it may be a file encoding problem?
16:31.56 mario_ Solved the problem by changing encoding to UTF-8 without BOM

14:08.55 gabbar1947 d_rossberg : regarding the ogl_loadMatrix(), using this i'm facing a datatype confliction between fastf_t and Glfloat. What I've currently done is one of the same thing, its just that I've not used the loadMatrix() function
14:38.57 d_rossberg what i meant is that the ogl matrix looks somehow transposed compared to the usual brl-cad matices
14:39.22 d_rossberg look at the wired assignment in ogl_loadMatrix()
14:51.09 gabbar1947 Oh fine ! That's a transpose.
14:52.22 gabbar1947 then the function can be used,.... its just that I need to use glGetFloatv and it requires Glfloat rather than fastf_t
15:04.31 d_rossberg i haven't checked if it is really a transpose but it looks like the indeces have to be changed
15:05.22 d_rossberg and, you should really try to test this, i.e. run the ogl display manager

05:35.43 brlcad also, see no reason why db_dirbuild() won't work on inmems, but it calls db5_scan and that does have ftell/rewind and offset calls in there, in the else clause, that would need to be changed (skipped)
05:36.55 brlcad if you can't figure out what to change, let me know and I could probably sort it out easily enough
05:37.50 brlcad all scan really does is set dbi_nrec, which is pretty trivial for an inmem, and call the handler callback

11:29.19 starseeker db_version I think also assumes a file pointer
11:29.59 starseeker although I guess we work around that with the in-mem by always setting it to 5 ahead of time...

00:35.55 starseeker brlcad: looking over the code, it appears that aside from the possible trouble spots of bwish and mged, only the various fb tools are keeping libtermio around. I'm not immediately understanding what about the fb tools makes the termio interfaces attractive... are there advantages compared to just (say) doing Tk windows or some such?
00:39.43 starseeker is eyeing what it would take to do away with libtermlib, libtermio and libcursor altogether, what with fbed, lgt and burst's termlib interface on the deprecated list

20:29.12 starseeker sigh
20:29.18 starseeker well, there's good news and bad news
20:29.34 starseeker the good news is that the simulate command appears to be functional on Windows
20:29.53 starseeker the bad news is that it seems to be broken again, on Linux and Windows
20:31.59 Stragus ponders the quantum superposition of functional and broken states and the interference patterns it produces
20:32.31 starseeker in this case, functional == it runs bullet and applys the results of the simulation to the .g
20:32.49 starseeker broken == the simulation is wrong
20:35.50 Notify 03BRL-CAD:starseeker * 70284 brlcad/trunk/TODO: identify a feature we will probably want going forward once we get bullet working properly...

16:00.59 mario_ Hi! I can't make rtweight load my .density file. It always throws segmentation fault. Any suggestions?
16:03.49 brlcad mario_: do you know how to use a debugger? what's the backtrace?
16:04.34 brlcad starseeker: gdal's CMakelist seems to be loading global cflags... now sure how to make it not do that
16:04.49 mario_ I'm using the Ubuntu subsystem on Windows, so I don't know how I would load a debugger there
16:05.08 brlcad type "gdb", does it run?
16:05.46 mario_ yes it does
16:05.54 brlcad then you have a debugger ;)
16:05.59 mario_ cool!
16:06.10 brlcad gdb --args path/to/rtweight ...options...
16:06.18 brlcad then at the gdb prompt:
16:06.22 brlcad gdb> run
16:06.40 brlcad it should segfault and bring you back to gdb> prompt
16:06.47 brlcad gdb> backtrace
16:07.05 brlcad that should say exactly where it died
16:07.33 mario_ oh thank you! I'll come back with the backtrace if i can't figure it out
16:07.47 brlcad k, sounds good :)
16:07.58 brlcad learning how to use a debugger is an essential skill, very useful
16:08.10 brlcad i suggest going through a quick 10 minute tutorial for the basics
16:08.23 brlcad far more powerful than printf() debugging that most people start with
16:08.36 mario_ I love the eclipse debugger ;) but never really used a command line one
16:08.54 mario_ ill go through some tutorial yeah
16:08.57 mario_ thank you for the suggestion!
16:09.19 brlcad the eclipse debugger is almost certainly gdb
16:09.32 mario_ ye but with a nice interface :P haha
16:09.35 brlcad this would just be teaching you what those buttons are doing
16:10.02 brlcad nice interface fails you when you need to go anywhere else, like now
16:10.14 brlcad or another platform, or another compiler, or another language, or ...
16:10.32 mario_ yeah true
16:10.34 brlcad that's why learning the lower-level concept is generally considered essential

18:14.01 starseeker ejno: are you able to do a successful bullet run, either with trunk or the revision where you wrapped up work on it?
18:14.20 starseeker I'm trying to drop the tank car on an arb8, and it's inter-penetrating
18:16.46 ejno hey starseeker, thanks, i'm looking into that
18:18.33 ejno would you mind uploading the db somewhere if you still have it?
18:18.36 starseeker sure
18:19.29 starseeker http://brlcad.org/~starseeker/sim_test.g
18:19.45 ejno thanks!
18:20.09 starseeker part of it may be the object size, but unless you scaled the tc before it did work...
18:20.42 starseeker if the scale is that critical, we'll need to auto-scale the scene down to bullet's dimensions and then scale the results back up for the .g somehow...
18:20.45 ejno so this used to work before i made the changes?
18:21.10 starseeker it doesn't seem so, based on my testing, but I was trying to reproduce your video demo scene
18:21.14 starseeker which did work...
18:21.25 starseeker I may have done something wrong
18:21.25 ejno ah
18:22.06 ejno it's probably related to the scaling
18:22.20 starseeker I've got another demo I'm trying to assemble - a scaled up ktank dropping onto our example dsp - that has similar issues even which I scaled the overall scene down
18:22.23 starseeker ndos
18:22.26 starseeker nods even
18:23.16 starseeker ejno: how hard would it be to pull the bbox of the scene, and scale it down pre-bullet for simulation so it fits in the "safe" size range?
18:23.30 starseeker then scale it back up after simulation
18:27.01 starseeker ejno: I may have lost a build definition or two (in particular float vs. double) when I pulled the bullet srcs under libged, so that's another possibility (although I'm seeing the same behavior with older builds, so it seems unlikely)
18:27.23 ejno it's something i've been thinking of. probably a week or so, and i'll work on it
18:27.37 starseeker ejno: cool, thank you!
18:28.02 ejno glad to do it
18:28.20 starseeker it's getting tantelizing now, with a demonstrated run on Windows :-)
18:29.29 starseeker if you like I can also prepare an example with the dsp/ktank setup, although that may need that feature we talked about earlier of generating sweep bounding boxes in the direction of motion to cut down the size of the pieces bullet is looking at...
18:34.41 ejno thank you, i agree though, that's probably not necessary until the scaling work is done
19:00.45 Stragus Eh, I didn't think Bullet would be satisfactory for your physics needs. It detects collisions _after_ the fact then artificially push things away until they don't collide
19:00.54 Stragus It's good enough for games I suppose

20:08.52 brlcad starseeker: I might have misread the output, but it looked like all the gdal tests were nearly all failing because of the -Wl,--no-undefined flag first passing successful but then causing all subsequent gdal tests to fail
20:09.28 brlcad and since gdal's header/type/etc tests happened before ours, the cached result seemed to be a lot disabled that shouldn't have been
20:14.38 brlcad Stragus: I don't recall having ever asserted bullet's simulation as being inadequate, at least not where you'd end up using it in cad modeling where it's almost entirely used to get objects to come into contact (e.g., per gravity) as part of some modeling operation or demonstration
20:15.23 brlcad now for v/l sim or anything high order, that's another issue ... wouldn't use it for that except maybe to fly out fragments

01:02.57 starseeker the "right" way to do it is probably to apply it just where it's needed in GDAL (per target) - if we're lucky we can apply it JUST to the gdal library target and leave it at that

18:31.01 brlcad cool: http://varun.ca/metaballs/
18:41.12 brlcad nice analysis of the repo conversion options... and things blender has tried (talked to Ton just last weekend)
18:42.19 brlcad would be good to summarize your work on a wiki page too, similar to http://brlcad.org/wiki/Cvs2svn ... maybe http://brlcad.org/wiki/Svn2git :)
18:43.18 brlcad sounds like reposurgeon might be the way to go, will just have to see what it does with the dangerous bits
18:53.42 brlcad the big ones I can think of offhand are the 22798 restructuring, the src/other and other large dir drop-and-readds (especially the ones that happened during CVS days), and edits to tagged releases
19:00.15 brlcad and to answer your question -- yeah, we can drop the oldest commits that have nothing to do with cad

03:58.23 brlcad wonders if erik ever saw / used http://www.cs.otago.ac.nz/homepages/andrew/papers/g2.pdf
05:18.23 Stragus Solving 6th polynomials, eh
05:21.47 Stragus By the way, I shared some idea about "curved triangles" with Christiaan Gribble (I assume you know him?). He said he would look into it but hasn't followed up, and I think there's some potential
06:43.59 *** join/#brlcad teepee (~teepee@unaffiliated/teepee)
06:45.21 brlcad Stragus: do you remember that indian guy that wanted to sell his curved triangles implementation back at rt06 in utah?
06:48.03 Stragus I don't!
06:48.37 Stragus I assume it's probably a different idea though?...
06:51.20 brlcad don't know if it was exactly the same, wasn't interested in his business attempt -- but only so many ways to curve a triangle, no? :)
06:52.09 Stragus Possibly :), it's a question of what data is stored, how the math is done, and how the ray intersection is done
06:52.37 Stragus I'll forward you by email a short overview I had written for Christiaan
06:53.43 Stragus Sent
06:54.33 Stragus I was mostly wondering if something like this has been done, or if anyone would like to try it
07:00.56 Stragus I mostly like the idea because you could take any regular standard triangle-based geometry, and make it very smooth with little extra storage; the ray intersection test is heavier, but that's less relevant each day
07:55.25 Caterpillar brlcad: I remember brlcad was accepted in last GSOC, wasn't it?

17:41.43 brlcad amritpal: hello back :)
17:42.12 amritpal brlcad, hi
17:43.17 amritpal brlcad, can I create a task that is related to my GSoC project (FreeCAD)? I have more experience in FreeCAD than BRL-CAD.
18:14.16 brlcad amritpal: there really wasn't enough mentoring support to handle coding tasks across different projects -- remember that these are kids with no experience, so even downloading becomes a task
18:14.33 brlcad we tried having separate instructions last year (when there was more mentoring support) and it did not go very well
18:14.43 brlcad very confusing for the kids
18:15.03 brlcad it may be possible if we can fit freecad onto the VM image without it getting too big
18:15.11 brlcad certainly possible to have non-coding tasks too
18:19.48 amritpal brlcad, how can I contribute then?
18:35.48 brlcad amritpal: how about interoperability tasks?
18:35.58 brlcad or design tasks specific to freecad
18:36.05 brlcad or documentation
18:36.47 brlcad e.g., "write a tutorial where you model a box in freecad and import it into brl-cad"
18:36.50 brlcad and then the reverse
18:37.20 brlcad maybe have them design an icon set
18:37.24 brlcad lots of possibilities
18:38.22 amritpal brlcad, yeah, let me brainstorming on these ideas.
18:39.39 brlcad oh, here's a possible idea that yorik mentioned a while ago
18:39.55 brlcad a bit of an advanced set of tasks, but possible if you can break it up
18:40.58 brlcad basically, have them create a BRL-CAD Benchmark in FreeCAD -- that way the target is clearly advanced students that already got over compilation hurdles
18:41.20 brlcad er, I mean a Workbench
18:41.53 brlcad similar to OpenSCAD's https://www.freecadweb.org/wiki/Workbenches

18:25.37 brlcad oh, hold the presses.. had compilation settings wrong for that test
18:26.12 brlcad to be continued... maybe faster after all, when all the optimization knobs are dialed in

01:33.41 brlcad neat idea ... http://tldr.sh
01:55.17 brlcad starseeker: gdal compile errors on -mavx and -mssse3 not being valid compiler flags, presumably need to test for them
02:34.59 brlcad think I might have sorted out a relatively easy fix
03:32.12 Stragus Why would -mavx and -mssse3 be invalid compiler flags? Both GCC and clang accept them...
03:42.16 brlcad either hardware or compiler version
03:42.39 brlcad it was on a 100-core Power (big endian) system

10:50.32 AndChat264089 Hello,sorry if this question seems quite basic.I do quite a bit of competetive programming on sites like codechef.For some time Ive been looking forward to open source and google code in 2017.I know c++ to a good extent including the data structures and dynamic programming,but I cant figure out where to begin in open source.All the projects and issues/bugs I see seem completely alien to me and I can't understand how my c++ s

11:42.42 AndChat264089 Okay,do I need to learn something else apart from the language? I've heard talks of frameworks and APIs?
11:51.31 Stragus There's a ton of APIs and libraries you could learn and use, but that all depends on the projects involved
11:51.51 Stragus For example, if you do 3D graphics, you might want to learn OpenGL

12:17.30 Stragus What parts would you like to work on? There's demand for OpenCL to trace rays on GPUs, for example

15:16.53 Notify 03BRL-CAD:brlcad * 70447 brlcad/trunk/src/libnmg/inter.c: underlying issue being warned is that someone set an upper limit without checking if it got exceeded.
15:21.50 starseeker brlcad: getting some include errors here, and I'm 99.9999% sure the Windows build is totally fried
15:22.12 starseeker even then, dropping ktank on the dsp example doesn't work, so either way we're not ready for prime time
15:25.04 brlcad yeah, hadn't even gotten to windows yet because of other build failures being worked out
15:25.35 starseeker nods
15:26.14 starseeker i've got to say in some ways the bullet source code (version 2.x anyway) is rather annoying
15:26.44 brlcad does libged/simulate/bullet build successfully?
15:26.47 starseeker supposes it would be an insane amount of work to recast the logic into our data types, but sometimes it's tempting to try
15:26.54 starseeker not for me currently
15:27.02 starseeker can't find headers
15:27.17 brlcad huh
15:27.25 starseeker brlcad: it's probably not worth fooling with with GCI about to kick off...
15:27.49 brlcad makes it a GCI task
15:27.52 starseeker if it worked I'd feel differently, but there's still a fair bit to do functionality wise
15:28.46 starseeker I have no clue what to do about the Windows build if we're not going to build bullet as part of libged - I tried DLL, I tried static, I tried adding exports to support DLL... all were rabbit holes
15:29.50 starseeker upstream apparently expects people to build it static and use it that way
15:30.02 brlcad that's curious though because any of those should work .. so is something wrong in BRLCAD_ADDLIB?
15:30.25 starseeker shakes his head - possibly, but I get the sense that bullet isn't designed/coded for DLL linking
15:30.48 starseeker I don't recall what went wrong with the static option - that could be me
15:30.52 brlcad well yeah, I get why that one would fail if there's not a symbol file
15:34.22 brlcad static doesn't require import/export mess so that's why I put it on the flag list
15:34.38 starseeker brlcad: we may be worse off than most because of the level at which we need to interface with bullet (feeding ray data to it...)
15:35.04 starseeker brlcad: worth trying - I did have a go with it, but I may have done something wrong
15:36.05 brlcad the big studios that hooked into bullet use it far harder and more complex than we're using :)
15:36.17 brlcad hm, looks like we're a little behind versioning too
15:36.26 brlcad another possibility
15:37.51 starseeker brlcad: they're also probably not shy about shoehorning it in any old way...
15:40.42 starseeker wonders if https://swiftshader.googlesource.com/SwiftShader might make a good candidate/alternative to Mesa to guarantee an OpenGL rendering capability in the event of driver problems...
15:41.55 brlcad well, I think we can sort it out easily enough either way .. it seems to be close
15:42.15 brlcad is src/libged/simulate/bullet/CMakeLists.txt file yours or from the bullet guys?
15:46.19 starseeker I think that one's me
15:47.14 starseeker IIRC, I pulled some bits from their other files
15:49.03 starseeker I was trying to at least avoid issues linking bullet's separate libraries, so I build one big library with all of the parts we need
15:54.19 brlcad nods, it's simple enough
15:56.24 starseeker I suppose I shouldn't ask this, but I wonder if we could mod qu3e more easily to use rays and be "good enough"
17:26.51 brlcad relevant: http://www.adrianboeing.com/pal/papers/p281-boeing.pdf
17:35.35 Notify 03BRL-CAD:brlcad * 70448 brlcad/trunk/CMakeLists.txt: running into a variety of other link-time-optimization bugs that can't be worked around. avoid LTO on busted versions. not easily detected in a feature test (looking not even possible outside of tailoring to compiler-specific bugs, which seems overkill).

14:51.40 Siddharth Hey guys
14:52.41 Siddharth This is my second time taking part in GCI
14:53.03 Siddharth And my first time with BRL-CAD
14:53.49 brlcad hi Siddharth! welcome
14:54.32 brlcad people are in and out all day, so just hang out if you like or install zulip and chat with us at brlcad.zulipchat.com
14:54.53 brlcad and ask questions when you get stuck on a task ;0

15:03.38 Siddharth Could anyone explain me the workbenches of freecad?
15:03.45 Siddharth What is Arch, Part, Draft, Sketcher, FEM ?
15:04.50 *** join/#brlcad kintel (~kintel@unaffiliated/kintel)
16:02.55 brlcad Siddharth: workbenches are basically plugins
16:03.18 brlcad Siddharth: it's a way to present a different vocaulary and interface to users
16:03.45 Siddharth Are they built in>
16:04.34 brlcad for example, say one guy is a building architect and another makes cars
16:05.29 brlcad i might make a workbench for the first that makes it easy to make floors, doors, walls, and windows
16:06.20 brlcad for the second, that's no use to him and would be distracting/cluttered, so I'd make him a different workbench with tools for designing wheels, lights, and maybe an extensive automobile parts catalog
16:06.37 brlcad they could be built in or not -- in freecad's case, I believe they bundle them in
16:06.58 brlcad you'd have to ask on the freecad forum -- our specialty is the brl-cad side of things
16:07.50 brlcad so with that same analogy, you could make a freecad workbench for brl-cad users, where you present users with tools that speak in brl-cad terms, make brl-cad objects, use brl-cad tools, etc
16:21.41 Siddharth Thanks a lot

17:15.53 Rakete1111 I have a file that I want to add to the project that uses C++11, but because CMake's minimum required version is 3.0.2, I can't use CMAKE_CXX_STANDARD. What should I do? Add the flags manually for gcc/clang, Intel and CL?

07:52.37 prathvi given on the website
07:52.48 gabbar1947 sounds good !
07:52.54 prathvi and there is no need to install x11 when you have x quartz
07:58.30 prathvi when i run tops it says error database is not open
08:00.49 brlcad xquartz is x11
08:01.18 brlcad there are sample databases inside of the application bundle
08:01.41 prathvi thanks :)
08:01.49 prathvi just figured it out
08:01.52 brlcad just run File -> Open -> Example Geometry
08:02.01 prathvi i drew a cube
08:02.07 prathvi and now did rt :)
08:02.10 brlcad there's more interesting samples ;)
08:02.26 prathvi i shall see them ;)
08:02.49 brlcad they're mostly simple demos, but there are a handful that are interesting
08:03.00 brlcad like tank_car.g
08:04.25 brlcad now that you're up and running, you can get credit for the beginner setup task, then try the two tutorial tasks
08:04.43 brlcad at least that's what I'd suggest
08:06.29 prathvi this is really exciting , excited to do more tasks

06:34.35 brlcad starseeker: c70462 doesn't look right ... suddenly places all throughout the code had to become aware of CMAKE_C_STD_FLAG?? having to call out a specific flag like that anywhere is a technical scope violation -- i'm sure you had a reason or it made things work, but is there a way to not have that propagate? the changes in misc/CMake/BRLCAD_CheckFunctions.cmake seem particularly wrong...
06:36.00 brlcad also, there are reports streaming in of build failures (and I just hit it myself) where the new stdc++11 flag is causing strict build failures (we don't compile clean with it just yet)

17:23.59 starseeker brlcad: some of those changes may be redundant - I was trying several things, and I may not have cleaned up properly. The main point was the standard flag needs to be universally used both for targets (which CMake does) and the testing macros (which CMake doesn't do)
17:25.38 starseeker just setting CMAKE_C(XX)_STANDARD will then result in the compile/run tests being done without the flag, with potentially different results
17:26.37 starseeker I can't set CMAKE_REQUIRED_FLAGS globally (I think...) because we're setting both C and C++ language standards and I didn't want to send the C++ flag to the C compiler and vice versa
17:27.46 starseeker it may be that setting CMAKE_C_FLAGS and CMAKE_CXX_FLAGS (lines 883/884) will take care of it now, but I haven't tested reverting the check macros yet
17:29.43 starseeker apparently I didn't test with a new enough compiler to pick up on C++11 issues
17:30.52 starseeker if we need to for GCI should be able to just change line 870 in CMakeLists.txt to the older standard

01:21.10 brlcad for example: for rt doing reads, lmdb makes little sense; for libged working on processing geometry transactions, lmdb makes fantastic sense; for librt doing random open/lookup/write/close calls, it won't likely help unless/until it became a v6 storage backend
01:36.12 brlcad for replacing DBNHASH for lookups and iterations, there are much faster in-memory-only solutions like redis or even sqlite (:memory:)
01:54.32 starseeker nods - makes sense
01:58.23 starseeker winces - redis would be a fair bit more work as a src/other dep compared to sqlite... wonder what the performance differential is

21:05.59 nmz787 basically I want the GUI controls to create new segments of Python code (i.e. for a sphere or other primitives), then my parser will convert this Python to TCL, then this converted to a .db, then that .db rendered on-screen
21:06.29 nmz787 currently my hack is to use mged to produce a png... then display that png file in a GUI image widget in Python/tkinter
21:07.13 nmz787 but obviously I could probably /somehow/ use the actual C++ GUI stuff BRL-CAD already has
21:08.38 nmz787 just not sure where the path of least resistance is... I can code in C/C++ (and do so for work) but I really am much much more productive in Python.... so I'd like to keep as much of the GUI view stuff in Python as possible, since it's obviously less important than the actual critical rendering code, and people will want to customize the GUI much much more than the backend
21:09.49 nmz787 but yeah, my PNG file hack is pretty slow to i.e. rotate a part on-screen... not intolerable, but it reminds me of scenes from movies from the 1980s where they are doing CAD on some ancient PC

23:50.38 brlcad_noob Hi there! Greetings from Earth! I'm starting to use BRL-CAD and learning more about ray-tracing applications, searched about ray-trace using BRL-CAD and discovered the cmd *burst*. The page on brlcad.org domain talking about running it, but the manual on the latest sourceforge tar had a bit more in-deep description. It would be really good if there was some tutorial using *burst* and *mged* for geometry analysis. Is there somethin
23:53.22 brlcad_noob the most interesting related link that I found is the https://brlcad.org/wiki/Early_Raytracing_History.
