BRL-CAD's IRC Bot (Nov 05 2019 at 04:47):TheJollyRoger@irc.freenode.net: Ahoy!
BRL-CAD's IRC Bot (Nov 05 2019 at 04:48):TheJollyRoger@irc.freenode.net: brlcad/Sean, I can see your pings and testing posts, what's up there?
Sean (Nov 05 2019 at 04:49):Hi TheJollyRoger! I'm working on setting up a bridge to our Zulip chat.
BRL-CAD's IRC Bot (Nov 05 2019 at 04:49):TheJollyRoger@irc.freenode.net: Ahoy! :D
BRL-CAD's IRC Bot (Nov 05 2019 at 04:49):TheJollyRoger@irc.freenode.net: Woah, wow! A bridge to another chat, that's awesome!
BRL-CAD's IRC Bot (Nov 05 2019 at 04:50):brlcad@irc.freenode.net: TheJollyRoger: that way, messages are bidirectional
BRL-CAD's IRC Bot (Nov 05 2019 at 04:50):TheJollyRoger@irc.freenode.net: That'll be great to reach out and meet more people, I'm looking forward to it ^_^!
BRL-CAD's IRC Bot (Nov 05 2019 at 04:50):TheJollyRoger@irc.freenode.net: Ooh. They can see us, and we can see them?
BRL-CAD's IRC Bot (Nov 05 2019 at 04:50):brlcad@irc.freenode.net: a tiny bit clunky with the way it has to relay nick names, but looks like it's working well.
BRL-CAD's IRC Bot (Nov 05 2019 at 04:50):TheJollyRoger@irc.freenode.net: Woohoo!
BRL-CAD's IRC Bot (Nov 05 2019 at 04:51):brlcad@irc.freenode.net: think they can only see people that talk
BRL-CAD's IRC Bot (Nov 05 2019 at 04:51):TheJollyRoger@irc.freenode.net: Got it, and us, likewise? We only see them if they say something?
BRL-CAD's IRC Bot (Nov 05 2019 at 04:55):brlcad@irc.freenode.net: yes
BRL-CAD's IRC Bot (Nov 05 2019 at 04:55):TheJollyRoger@irc.freenode.net: Got it.
BRL-CAD's IRC Bot (Nov 05 2019 at 04:58):TheJollyRoger@irc.freenode.net: Sometime when I have more time I'm going to dig into the BRL CAD documentation. I'll have a ton of questions, I just want to make sure I get up to date on the knowledge base so I can ask the right ones.
BRL-CAD's IRC Bot (Nov 05 2019 at 04:59):brlcad@irc.freenode.net: Sure thing, ask away.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:00):TheJollyRoger@irc.freenode.net: THanks ^_^. I don't have any particular questions at this moment, I've just been fooling around with MGED so far and wondering if there's anything like a graphical frontend to it, since I'm used to doing sketching and extrusion and sweep operations in Creo and NX.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:00):TheJollyRoger@irc.freenode.net: Heh, okay, I guess that is a question XP.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:15):brlcad@irc.freenode.net: BRL-CAD also focuses on 3d solid modeling techniques, and sketching comes from the 2d drafting realm. That said, you can check out the Sketch Editor on the menu for basic editing. They can be extruded with an "extrude" object, revolved with a "revolv" object.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:15):TheJollyRoger@irc.freenode.net: Oh perfect.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:16):brlcad@irc.freenode.net: *revolve
BRL-CAD's IRC Bot (Nov 05 2019 at 05:16):brlcad@irc.freenode.net: this is a non-GUI overview of sketch: pip install -r zulip/integrations/bridge_with_irc/requirements.txt
BRL-CAD's IRC Bot (Nov 05 2019 at 05:16):brlcad@irc.freenode.net: Configure the bridge
BRL-CAD's IRC Bot (Nov 05 2019 at 05:16):brlcad@irc.freenode.net: oop, this link: https://brlcad.org/wiki/Sketch
BRL-CAD's IRC Bot (Nov 05 2019 at 05:17):brlcad@irc.freenode.net: and extrude: https://brlcad.org/wiki/Extrude
BRL-CAD's IRC Bot (Nov 05 2019 at 05:18):TheJollyRoger@irc.freenode.net: MGED almost reminds me a little of using APT for tool paths.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:18):TheJollyRoger@irc.freenode.net: Almost. Kinda. A little bit maybe.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:19):brlcad@irc.freenode.net: yeah, that's a very low-level overview. There's a graphical tutorial somewhere where you don't hit the command line, but I don't have it handy.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:19):TheJollyRoger@irc.freenode.net: Got it. I'll search around then!
BRL-CAD's IRC Bot (Nov 05 2019 at 05:20):brlcad@irc.freenode.net: the "ebm" extruded bitmap primitive is a distant cousin. it's definitely covered in the Principles of Effective Modeling at https://brlcad.org/wiki/Documentation
BRL-CAD's IRC Bot (Nov 05 2019 at 05:24):TheJollyRoger@irc.freenode.net: Whew. I'll have to study this, then!
BRL-CAD's IRC Bot (Nov 05 2019 at 05:24):TheJollyRoger@irc.freenode.net: Ehehe. I'm kinda nervous.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:25):TheJollyRoger@irc.freenode.net: Not gonna lie, the tools and UI do look kinda intimidating. I generally use the commandline for most of my day-to-day tasks on the OS but trying to fly blind is a little... I dunno, it's gonna mean I'll have to really think the design through up front instead of just throwing down a sketch and then adjusting it to size later.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:26):brlcad@irc.freenode.net: Yes, it's conceptually quite a different method altogether.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:26):TheJollyRoger@irc.freenode.net: Yeah.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:27):brlcad@irc.freenode.net: Expert modelers tell me they're just as proficient if not more proficient as they are in other CAD, but the learning curve is definitely steep and the methods are different, often incompatible.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:28):brlcad@irc.freenode.net: We're working on usability and core features that affect it, but it's going to be a process and it takes time to implement every (seemingly little) feature.
Sean (Nov 05 2019 at 05:28):Testing from #general
BRL-CAD's IRC Bot (Nov 05 2019 at 05:30):brlcad@irc.freenode.net: Testing
BRL-CAD's IRC Bot (Nov 05 2019 at 05:34):brlcad@irc.freenode.net: all done testing, this looks like a usable bridge even if it is limited to individual streams. added one on the gci channel just in case since chatter on that will be kicking up real soon.
BRL-CAD's IRC Bot (Nov 05 2019 at 05:34):TheJollyRoger@irc.freenode.net: Woohoo!
BRL-CAD's IRC Bot (Nov 05 2019 at 09:11):Freso@irc.freenode.net: brlcad: Alright. I probably won’t touch the script again before January now though, so we’ll see. :p
BRL-CAD's IRC Bot (Nov 05 2019 at 12:32):brlcad@irc.freenode.net: Freso: that's a really cool patch; didn't even occur to me to use it for the inverse
BRL-CAD's IRC Bot (Nov 05 2019 at 23:28):Freso@irc.freenode.net: brlcad: :)
Sean (Nov 06 2019 at 04:00):@starseeker: https://docs.hunter.sh/en/latest/#
Sean (Nov 06 2019 at 04:01):cmake package management
BRL-CAD's IRC Bot (Nov 06 2019 at 04:03):brlcad@irc.freenode.net: hm, squirrely -- hopefully you still got a highlight
Sean (Nov 06 2019 at 05:44):@starseeker also related to the earlier mention about shape construction from video, this is the other project that came to mind with some of the latest progress: https://www.cs.cmu.edu/~reconstruction/colmap.html
BRL-CAD's IRC Bot (Nov 06 2019 at 12:39):starseeker@irc.freenode.net: brlcad: if you mean highlighted in the sense of bolding the line or some such, not really - just the prepended names
BRL-CAD's IRC Bot (Nov 06 2019 at 12:40):starseeker@irc.freenode.net: still, nifty
BRL-CAD's IRC Bot (Nov 06 2019 at 13:24):brlcad@irc.freenode.net: starseeker: did you get an IRC "alert" because your nam was mentiond. in irssi, for example, it colors the sender's name orange instead of my terminal color (green)
jaideep seth (Nov 06 2019 at 13:31):I was a Student Developer in the Google Summer of Code 2019 and would like to mentor projects in the Google Code in 2019.
Please guide me on what is the process to apply.
Thank you!
Sean (Nov 08 2019 at 13:40):Hi @jaideep seth, welcome and thank you for your interest! What brings you to BRL-CAD?
Sean (Nov 08 2019 at 13:41):For what it's worth, to be an effective mentor, you'll need to be an active contributor. You’re more than welcome to be a mentor, but you’ll need to demonstrate you can be a capable contributor over the next couple weeks by submitting work, show you can be independently productive, show you’re familiar with the code, show you are or will be effective at giving advice to others, etc.
Sean (Nov 08 2019 at 13:42):If you have a reference to your GSoC work (who was your mentor), that would be good to know.
BRL-CAD's IRC Bot (Nov 08 2019 at 13:48):TheJollyRoger@irc.freenode.net: Yay, the bridge seems to be working ^_^
Sean (Nov 08 2019 at 13:48)::)
BRL-CAD's IRC Bot (Nov 08 2019 at 13:49):TheJollyRoger@irc.freenode.net: Ahoy Cap'n! ^_^
Sean (Nov 08 2019 at 13:49):greetings! happy friday!
BRL-CAD's IRC Bot (Nov 08 2019 at 13:49):TheJollyRoger@irc.freenode.net: Yarr!
BRL-CAD's IRC Bot (Nov 08 2019 at 13:52):TheJollyRoger@irc.freenode.net: I gotta fix up some stuff but I should be around more later today!
BRL-CAD's IRC Bot (Nov 08 2019 at 13:54):brlcad@irc.freenode.net: sounds good
BRL-CAD's IRC Bot (Nov 08 2019 at 13:55):teepee_@irc.freenode.net: brlcad is there someone who would look at the DXF code? I can help, but I don't think I can manage the time to be actual mentor
BRL-CAD's IRC Bot (Nov 08 2019 at 13:56):teepee_@irc.freenode.net: I just saw it mentioned somewhere (on the mailing list I think?)
BRL-CAD's IRC Bot (Nov 08 2019 at 13:56):brlcad@irc.freenode.net: teepee_: absolutely -- that's one I already have a task chain started for since it's more of a priority
BRL-CAD's IRC Bot (Nov 08 2019 at 13:58):brlcad@irc.freenode.net: would xuwei be interested in mentoring it?
BRL-CAD's IRC Bot (Nov 08 2019 at 13:58):teepee_@irc.freenode.net: at some point he said he'd like to continue working on it but I have not heard back
BRL-CAD's IRC Bot (Nov 08 2019 at 13:58):teepee_@irc.freenode.net: I can try to catch him via mail
BRL-CAD's IRC Bot (Nov 08 2019 at 13:58):brlcad@irc.freenode.net: if not mentor it, at least maybe help define a list of the things it needs next
BRL-CAD's IRC Bot (Nov 08 2019 at 13:59):brlcad@irc.freenode.net: he would get a free t-shirt out of it ;)
BRL-CAD's IRC Bot (Nov 08 2019 at 14:00):teepee_@irc.freenode.net: an overview is in https://github.com/openscad/openscad/issues/3044 but I guess it's too high level to directly map to gci tasks
BRL-CAD's IRC Bot (Nov 08 2019 at 14:03):brlcad@irc.freenode.net: it's better than nothing, but yeah. gci also isn't good for architecture or design (figuring things out), which is a lot of what's in the "What's left" section.
BRL-CAD's IRC Bot (Nov 08 2019 at 14:04):teepee_@irc.freenode.net: if there's someone with some basic c++ knowledge there could be tasks to move more c style code to c++ style
BRL-CAD's IRC Bot (Nov 08 2019 at 14:04):brlcad@irc.freenode.net: what it would be great for is things like creating test data, unit tests, implementing a spline fitting function, creating a summary table of what entities are supported on import/export, etc :)
BRL-CAD's IRC Bot (Nov 08 2019 at 14:05):teepee_@irc.freenode.net: nothing done for export yet
BRL-CAD's IRC Bot (Nov 08 2019 at 14:40):brlcad@irc.freenode.net: so that's an easy table to fill out ;)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:05):teepee_@irc.freenode.net: is the list of tasks already online somewhere?
BRL-CAD's IRC Bot (Nov 08 2019 at 15:06):brlcad@irc.freenode.net: not yet, but this was the starter list from last time and several of them are keepers: https://brlcad.org/wiki/Google_Code_In/2017/Tasks
jaideep seth (Nov 08 2019 at 15:08):If you have a reference to your GSoC work (who was your mentor), that would be good to know.
Project 16.1 of INCF in GSoC 19 https://summerofcode.withgoogle.com/projects/#5177840062955520
I will strive to contribute to the code base of BRL-CAD over the next 2 weeks.
Please consider the tasks I submit for potential GCI 2019 one (is there a spread sheet or something equivalent being circulated, could u tell me where?)
Thank you!
BRL-CAD's IRC Bot (Nov 08 2019 at 15:10):brlcad@irc.freenode.net: teepee_: how possible would it be to extract either .scad or .csg as a (non-gpl) library?
BRL-CAD's IRC Bot (Nov 08 2019 at 15:12):teepee_@irc.freenode.net: just the parser should be reasonable
BRL-CAD's IRC Bot (Nov 08 2019 at 15:12):brlcad@irc.freenode.net: @jaideep seth: can you ask your mentor to send me an e-mail or send me their e-mail/irc so I can talk with them?
BRL-CAD's IRC Bot (Nov 08 2019 at 15:12):teepee_@irc.freenode.net: including also the processing step to generate actual geometry is probably a big pile of work
BRL-CAD's IRC Bot (Nov 08 2019 at 15:13):brlcad@irc.freenode.net: no geometry generation, it can stay in expression/implicit form
BRL-CAD's IRC Bot (Nov 08 2019 at 15:13):brlcad@irc.freenode.net: don't want triangles ;)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:13):teepee_@irc.freenode.net: you'll get minkowski then :P
BRL-CAD's IRC Bot (Nov 08 2019 at 15:14):brlcad@irc.freenode.net: it's harkening back to what we talked about a couple years ago
BRL-CAD's IRC Bot (Nov 08 2019 at 15:14):teepee_@irc.freenode.net: but yes, that would basically stop at the AST
BRL-CAD's IRC Bot (Nov 08 2019 at 15:14):brlcad@irc.freenode.net: possibility of full round trip mapping between (or outright replacement) of .g to .csg
BRL-CAD's IRC Bot (Nov 08 2019 at 15:14):teepee_@irc.freenode.net: which I would like to split out better too, even for just internal use
BRL-CAD's IRC Bot (Nov 08 2019 at 15:16):brlcad@irc.freenode.net: minkowski would become a new object type in brl-cad's taxonomy, either than or an editing command that evaluates (which is how hull is implemented)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:16):teepee_@irc.freenode.net: right now the AST nodes know how to evaluate themselves but it would be much cleaner to use handle that via visitors
BRL-CAD's IRC Bot (Nov 08 2019 at 15:16):brlcad@irc.freenode.net: s/than/that/
BRL-CAD's IRC Bot (Nov 08 2019 at 15:17):brlcad@irc.freenode.net: can you send me a source code link? I can take a look and see if it's at all something GCI students could start to tackle
BRL-CAD's IRC Bot (Nov 08 2019 at 15:18):brlcad@irc.freenode.net: they can't do the architecture, but they could take care of a lot of other details and make serious progress
BRL-CAD's IRC Bot (Nov 08 2019 at 15:18):teepee_@irc.freenode.net: entry point is the bison parser : https://github.com/openscad/openscad/blob/master/src/parser.y
BRL-CAD's IRC Bot (Nov 08 2019 at 15:18):brlcad@irc.freenode.net: oh no.. yaaaacc
BRL-CAD's IRC Bot (Nov 08 2019 at 15:18):brlcad@irc.freenode.net: :)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:19):brlcad@irc.freenode.net: how do you manage than on windows? bison for windows?
BRL-CAD's IRC Bot (Nov 08 2019 at 15:20):teepee_@irc.freenode.net: MXE as build environment - that's running on Linux
BRL-CAD's IRC Bot (Nov 08 2019 at 15:21):teepee_@irc.freenode.net: there's a mostly working VS build though using vcpkg - that is getting some bison implementation from somewhere else
BRL-CAD's IRC Bot (Nov 08 2019 at 15:22):teepee_@irc.freenode.net: command line call is : https://github.com/openscad/openscad/blob/master/src/openscad.cc#L337 which puts the AST into 'root_module'
BRL-CAD's IRC Bot (Nov 08 2019 at 15:22):teepee_@irc.freenode.net: and evaluation should be then : https://github.com/openscad/openscad/blob/master/src/openscad.cc#L362
BRL-CAD's IRC Bot (Nov 08 2019 at 15:23):brlcad@irc.freenode.net: if it were extracted, what license do you think you'd use? able to do a permissive?
BRL-CAD's IRC Bot (Nov 08 2019 at 15:29):teepee_@irc.freenode.net: I suppose that would be possible, there was some discussion about that already - we'd need to check with kintel about the details though
BRL-CAD's IRC Bot (Nov 08 2019 at 15:30):teepee_@irc.freenode.net: I know he would not have a problem with making it MIT but I don't know who else has worked on that part and would have a say in that
BRL-CAD's IRC Bot (Nov 08 2019 at 15:31):kintel@irc.freenode.net: I started working on extracting the file I/O and AST into a library a while ago
jaideep seth (Nov 08 2019 at 15:31):brlcad@irc.freenode.net: jaideep seth: can you ask your mentor to send me an e-mail or send me their e-mail/irc so I can talk with them?
My main mentor was Mark Watts, Ph.D student with University of Texas at Dallas.
Contact Details:
watts.mark2015@gmail.com
mark@openworm.org
There are many tasks ( 100s with many instances ) for each org in GCI 2019, I can help with making some ( while I try to get a commit in the BRL-CAD codbase)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:32):kintel@irc.freenode.net: And the intent was a BSD-style interop library
BRL-CAD's IRC Bot (Nov 08 2019 at 15:32):kintel@irc.freenode.net: https://github.com/openscad/openscad/pull/1743
BRL-CAD's IRC Bot (Nov 08 2019 at 15:33):kintel@irc.freenode.net: There's a bit of architecture and refactoring work needed. Not quite student material right now
BRL-CAD's IRC Bot (Nov 08 2019 at 15:33):teepee_@irc.freenode.net: Ah, right, that's what I remembered :)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:33):kintel@irc.freenode.net: Once we can preserve use/include as AST nodes, that would greatly simplify the next steps
BRL-CAD's IRC Bot (Nov 08 2019 at 15:33):teepee_@irc.freenode.net: maybe some tasks for moving into the direction and re-architecture later?
Sean (Nov 08 2019 at 15:33):We converted all of our flex and bison in just a few days to a compatible system that is cross platform
BRL-CAD's IRC Bot (Nov 08 2019 at 15:34):kintel@irc.freenode.net: The coupling is still a bit high to just separate I think, but it's easier to discover if taking a stab at it :)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:35):teepee_@irc.freenode.net: on my list would be some cleanup anyway - like getting all the code out of the parser.y
BRL-CAD's IRC Bot (Nov 08 2019 at 15:35):kintel@irc.freenode.net: But yeah, reorganizing files and build systems could prob. be done separately
BRL-CAD's IRC Bot (Nov 08 2019 at 15:35):kintel@irc.freenode.net: Perhaps motivation get the coding style update merged first :)
BRL-CAD's IRC Bot (Nov 08 2019 at 15:36):teepee_@irc.freenode.net: right, I guess that's probably a very good point now anyway
BRL-CAD's IRC Bot (Nov 08 2019 at 15:36):teepee_@irc.freenode.net: getting out a patch release is pretty much prepared in the branch already
BRL-CAD's IRC Bot (Nov 08 2019 at 15:36):teepee_@irc.freenode.net: I think there's only 2 small patches I need to cherry pick
BRL-CAD's IRC Bot (Nov 08 2019 at 15:37):teepee_@irc.freenode.net: so otherwise we are up for next release but not very soon realistically :D
Sean (Nov 08 2019 at 15:37):Yeah I think there’s probably a few things GCI could do here
BRL-CAD's IRC Bot (Nov 08 2019 at 15:38):teepee_@irc.freenode.net: I agree with kintel we should not try to go for full separation just yet
BRL-CAD's IRC Bot (Nov 08 2019 at 15:38):teepee_@irc.freenode.net: but preparing the move into that direction should still be able to produce a number of smaller topics that could fit gci
BRL-CAD's IRC Bot (Nov 08 2019 at 15:39):teepee_@irc.freenode.net: those are supposed to be like 2-4h or something like that?
Sean (Nov 08 2019 at 17:29):More like 1-2 hours for a core dev, someone fully experienced and set up. Target is for it to be something an average student could do in less than a day even if not set up, ideally in the 1-4 hr timeframe depending on their experience.
Sean (Nov 08 2019 at 17:31):So if they’re really good, it’s still at least an hour of work, and if they’re not, it can still figure it out without getting frustrated or being impossible
BRL-CAD's IRC Bot (Nov 18 2019 at 18:48):brlcad@irc.freenode.net: welp, first official restart of the irc bridge...

BRL-CAD's IRC Bot (Nov 23 2019 at 21:42):dev__@irc.freenode.net: Hello! I am new here can anyone tell me to how to start with?
BRL-CAD's IRC Bot (Nov 23 2019 at 21:42):dev__@irc.freenode.net: Thank you
Adithya Anilkumar (Nov 24 2019 at 04:27):Hi guys,
I am Adithya from India. I am new to BRL-CAD and am looking for ways to start contributing to the same. I am a GCI -18 and 17 participant and have experience with python , Django and JavaScript. Looking forward to working with BRL-CAD
BRL-CAD's IRC Bot (Nov 24 2019 at 07:44):TheJollyRoger@irc.freenode.net: Ahoy Adithya Anilkumar! ^_^
Sean (Nov 24 2019 at 15:01):Welcome @Adithya Anilkumar !
Adithya Anilkumar (Nov 24 2019 at 16:05):Is there anything i could help with?
Sean (Nov 24 2019 at 16:05):in what regard? of course, always ;)
Adithya Anilkumar (Nov 24 2019 at 16:06):In regards tp beginer Friendly issues
BRL-CAD's IRC Bot (Nov 25 2019 at 20:33):brlcad@irc.freenode.net: @Adithya Anilkumar: yes, there are many listed in the TODO file. for example, you could add support for multiple files to the dbconcat command
BRL-CAD's IRC Bot (Nov 25 2019 at 20:33):brlcad@irc.freenode.net: that's just a simple loop
Jeffrey Liu (Dec 02 2019 at 18:43):Hi, I'm participating in GCI 2019 (as Jebbly). At the moment, I am most interested in the Appleseed integration tasks as well as the 3D modelling tasks.
Sean (Dec 02 2019 at 18:59):hi @Jeffrey Liu and welcome! your name is super familiar... have you ben involved already?
Jeffrey Liu (Dec 02 2019 at 19:32):Hi! Yes, a little bit - I planned on participating in Google Code-in and noticed that BRL-CAD was one of the organizations, so I wanted to develop a better understanding of BRL-CAD beforehand because I have an interest in computer graphics. I had some issues compiling on Debian which I asked about over here, but it worked fine on Windows.
Sean (Dec 02 2019 at 19:51):ah, that's outstanding then
Jeffrey Liu (Dec 02 2019 at 21:13):Hey I just started the introduction to 3d modeling task; would this screenshot be enough for the command line? lesson01_cli.png.jpg
Sean (Dec 02 2019 at 21:14):that looks good, but I believe the intent is to show the rt usage statement
Sean (Dec 02 2019 at 21:15):since you already have geometry drawn, it rendered it. try running "Z" then "rt".
Sean (Dec 02 2019 at 21:15):/me writes up a checker's modeling task next
Jeffrey Liu (Dec 02 2019 at 21:21):Sorry I might be misunderstanding something, but isn't the rt usage statement for the compiling from source task?
Sean (Dec 02 2019 at 21:21):you're right, I thought that's the one you were referring to
Sean (Dec 02 2019 at 21:24):ah right, so yeah, that'd work for the screenshot for the first one
Sean (Dec 02 2019 at 21:24):note you can combine them, "Alternatively, run "rt" after "ae 45 45" and include the rt window in a full screenshot. "
Sean (Dec 02 2019 at 21:24):so your screenshot has the command window with your name and the rt window showing the render in the same image
Jeffrey Liu (Dec 02 2019 at 21:25):Oh ok, that makes things easier. Thank you!
BRL-CAD's IRC Bot (Dec 03 2019 at 01:19):starseeker@irc.freenode.net: brlcad: getting a unit test failure for the redblack implementation on latest ubuntu
Sean (Dec 03 2019 at 01:27):starseeker, any details? that seems random..

BRL-CAD's IRC Bot (Dec 03 2019 at 01:35):starseeker@irc.freenode.net: actually, the line numbers won't match - let me revert and rerun

BRL-CAD's IRC Bot (Dec 03 2019 at 01:37):starseeker@irc.freenode.net: we make almost no use of it
BRL-CAD's IRC Bot (Dec 03 2019 at 01:38):brlcad@irc.freenode.net: try updating it to r70981 ... pre-bu_list elimination, possibly gone awry
BRL-CAD's IRC Bot (Dec 03 2019 at 01:44):starseeker@irc.freenode.net: 71372 has it - that's right before the bu_list removal commit...
BRL-CAD's IRC Bot (Dec 03 2019 at 01:44):brlcad@irc.freenode.net: has it as in still crashes?
BRL-CAD's IRC Bot (Dec 03 2019 at 01:44):starseeker@irc.freenode.net: yep
BRL-CAD's IRC Bot (Dec 03 2019 at 01:44):brlcad@irc.freenode.net: rather, still reports memory issue
BRL-CAD's IRC Bot (Dec 03 2019 at 01:44):starseeker@irc.freenode.net: it'll crash outside of valgrind
BRL-CAD's IRC Bot (Dec 03 2019 at 01:49):starseeker@irc.freenode.net: ditto 70981
BRL-CAD's IRC Bot (Dec 03 2019 at 01:50):brlcad@irc.freenode.net: debugging
BRL-CAD's IRC Bot (Dec 03 2019 at 01:52):brlcad@irc.freenode.net: at a glance, I think the problem is just sillyness in bu_rb_delete()
BRL-CAD's IRC Bot (Dec 03 2019 at 01:52):brlcad@irc.freenode.net: deletes notes, then deletes the container that was holding the nodes, but it didn't take the pointers to them out of the container
BRL-CAD's IRC Bot (Dec 03 2019 at 01:53):brlcad@irc.freenode.net: looking to confirm it directly
BRL-CAD's IRC Bot (Dec 03 2019 at 01:54):brlcad@irc.freenode.net: quick test-- can you comment out line 595 in libbu/redblack.c and see if it still barks. not the proper fix, but would help confirm the locality..
BRL-CAD's IRC Bot (Dec 03 2019 at 01:57):starseeker@irc.freenode.net: still segfaults with that commented out
BRL-CAD's IRC Bot (Dec 03 2019 at 01:58):starseeker@irc.freenode.net: brlcad: we've had a lot of problems with this code over the years - would it be worth it to consider replacing the guts with something like https://github.com/openbsd/src/tree/master/usr.sbin/nsd ?
BRL-CAD's IRC Bot (Dec 03 2019 at 01:58):starseeker@irc.freenode.net: https://github.com/openbsd/src/blob/master/usr.sbin/nsd/rbtree.c rather
BRL-CAD's IRC Bot (Dec 03 2019 at 02:04):starseeker@irc.freenode.net: couple others floating around... netbsd has one, looks like...
BRL-CAD's IRC Bot (Dec 03 2019 at 02:11):starseeker@irc.freenode.net: as near as I can tell, we have two uses of libbu's redblack in our code - glint and pixcount
BRL-CAD's IRC Bot (Dec 03 2019 at 02:33):brlcad@irc.freenode.net: I would rather eliminate it outright for an STL container (std::map and std::set use redblack under the hood, iirc)
BRL-CAD's IRC Bot (Dec 03 2019 at 02:33):brlcad@irc.freenode.net: pixcount needs nothing of the sort
BRL-CAD's IRC Bot (Dec 03 2019 at 02:33):brlcad@irc.freenode.net: glint could be adapted
BRL-CAD's IRC Bot (Dec 03 2019 at 02:35):starseeker@irc.freenode.net: As an experiment I switched those two to C++ files - no trouble
BRL-CAD's IRC Bot (Dec 03 2019 at 02:36):starseeker@irc.freenode.net: Do we need to eliminate those uses before we list it as deprecated?
BRL-CAD's IRC Bot (Dec 03 2019 at 02:37):brlcad@irc.freenode.net: no
BRL-CAD's IRC Bot (Dec 03 2019 at 02:38):brlcad@irc.freenode.net: it's poor form in general, but not a rule or anything. deprecation is an independent announcement to everone else, so it just looks fishy when we'r still using it
BRL-CAD's IRC Bot (Dec 03 2019 at 02:38):starseeker@irc.freenode.net: I think it's worth doing in this case - I want to get it into CHANGES for the release, but I don't have time to disassemble glint right now...
BRL-CAD's IRC Bot (Dec 03 2019 at 02:39):starseeker@irc.freenode.net: if I do that I'll start looking at consolidating it with the MGED lint command
BRL-CAD's IRC Bot (Dec 03 2019 at 02:39):brlcad@irc.freenode.net: pixcount is just using it as an RGB color hash, that directly translates to a std::map<>
BRL-CAD's IRC Bot (Dec 03 2019 at 02:41):brlcad@irc.freenode.net: heck, probably a simple std::map<int32_t> with RGBA as the key would work perfectly
BRL-CAD's IRC Bot (Dec 03 2019 at 04:01):brlcad@irc.freenode.net: created a GCI task to re-implement it. it's perfectly scoped for gci.
Himanshu (Dec 03 2019 at 11:43):hello guys
:)
Himanshu (Dec 03 2019 at 11:49):ping @Jeffrey Liu
Jeffrey Liu (Dec 03 2019 at 11:49):Hello!
Himanshu (Dec 03 2019 at 11:49):do you know where to find a sample geometry file ?
Himanshu (Dec 03 2019 at 11:50):hello :)
Himanshu (Dec 03 2019 at 11:55):btw where are you from ?
Jeffrey Liu (Dec 03 2019 at 11:56):Hm, sorry I didn't do that task so I'm not quite sure; have you looked at the db directory from the source files though?
Jeffrey Liu (Dec 03 2019 at 11:56):I'm from the United States, how about you?
Himanshu (Dec 03 2019 at 11:57):I am from India
Himanshu (Dec 03 2019 at 11:57):okay I will continue searching on
Himanshu (Dec 03 2019 at 11:58):btw do you have any idea of it's extension ?
Himanshu (Dec 03 2019 at 12:00):looks like MGED extension
Himanshu (Dec 03 2019 at 12:02):hello @Panda (Gauravjeet Singh) where I can find a sample geometry file ?
Himanshu (Dec 03 2019 at 12:02):I am currently working on Compile and Install BRL-CAD from source code
Himanshu (Dec 03 2019 at 12:03):but I can't find a geometry file
Daniel Rossberg (Dec 03 2019 at 12:03):Did you already install BRL-CAD?
Himanshu (Dec 03 2019 at 12:03):yes
Jeffrey Liu (Dec 03 2019 at 12:05):The db directory has some asc (ASCII databases) that I was able to import
Daniel Rossberg (Dec 03 2019 at 12:05):Then, look at the share/db directory in your installation. There, you should find a lot of *.g files.
Himanshu (Dec 03 2019 at 12:07):yeah got it
Himanshu (Dec 03 2019 at 12:11):btw I got raytrace aborted while using rt @Sahibpreet Kaur
Himanshu (Dec 03 2019 at 12:12):what does that mean ?
Himanshu (Dec 03 2019 at 12:17):
Daniel Rossberg (Dec 03 2019 at 12:17):Screenshot?
This can happen, if you close the ray-trace window by clicking on the "x" (i.e. the usual way). Try to close it with a right mouse click inside the window.
Himanshu (Dec 03 2019 at 12:18):what if I closed with Ctrl+C in terminal ? @Daniel Rossberg
Daniel Rossberg (Dec 03 2019 at 12:18):Ah, okay. Type tops in mged and then draw with one of the displayed objects, which looks best.
Daniel Rossberg (Dec 03 2019 at 12:19):what if I closed with Ctrl+C in terminal ? Daniel Rossberg
Try it :wink:
Himanshu (Dec 03 2019 at 12:20):what if I closed with Ctrl+C in terminal ? Daniel Rossberg
Try it :wink:
It closes two windows simultaneously
Himanshu (Dec 03 2019 at 12:20):i also tried with other .g and same ray trace abort happen
Daniel Rossberg (Dec 03 2019 at 12:21):Did you select a group for drawing?
Himanshu (Dec 03 2019 at 12:22):nah
Himanshu (Dec 03 2019 at 12:22):just one .g file
Himanshu (Dec 03 2019 at 12:22):when I run bin/mged, it gives me two windows
Daniel Rossberg (Dec 03 2019 at 12:23):Okay, I see. For this task (compile and install), wee need to see this error message. This is intended there!
Himanshu (Dec 03 2019 at 12:23):
Daniel Rossberg (Dec 03 2019 at 12:24):Your first screen shot is what's needed to complete the task.
Daniel Rossberg (Dec 03 2019 at 12:25):However, if you want to see something, you have to select an object for displaying first. (with the procedure I described here)
Himanshu (Dec 03 2019 at 12:25):btw @Daniel Rossberg I tried with bin/archer and same ray trace abort
Himanshu (Dec 03 2019 at 12:25):However, if you want to see something, you have to select an object for displaying first. (with the procedure I described here)
yeah okay
Daniel Rossberg (Dec 03 2019 at 12:26):As I said: Thats okay if no object for displaying was selected.
Himanshu (Dec 03 2019 at 12:28):himanshu@asus:~/brlcad-code/brlcad-build
$ bin/archer
Raytrace aborted.
Himanshu (Dec 03 2019 at 12:31):@Daniel Rossberg so should I submit the task ?
Daniel Rossberg (Dec 03 2019 at 12:36):Yes, the error message is the thing we want to see. Type your name in the mged command prompt, make a screen shot, and submit it.
Himanshu (Dec 03 2019 at 12:38):done

Mayank Goyal (Dec 03 2019 at 12:57):I am on the task: Learn basic 3D modeling using BRL-CAD, part #1 of 2
Mayank Goyal (Dec 03 2019 at 12:57):I am not able to understand what all lessons to do
Sahibpreet Kaur (Dec 03 2019 at 12:59):Have you installed BRL-CAD on your system?
Mayank Goyal (Dec 03 2019 at 12:59):Yes , I have installed
Mayank Goyal (Dec 03 2019 at 13:00):Actually there are a lot of topics and under the introduction the mged, There are 16 lessons
Sahibpreet Kaur (Dec 03 2019 at 13:00):Here is the link to the MGED tutorial: http://brlcad.org/VolumeII-Introduction_to_MGED.pdf
Sahibpreet Kaur (Dec 03 2019 at 13:01):Yes, but the task states to complete lesson 1 to 8. What didn't you understand?
Mayank Goyal (Dec 03 2019 at 13:02):Lesson 1 to 8 in http://brlcad.org/VolumeII-Introduction_to_MGED.pdf
Sahibpreet Kaur (Dec 03 2019 at 13:02):Yes
Mayank Goyal (Dec 03 2019 at 13:03):And what is ae 45 45
Sahibpreet Kaur (Dec 03 2019 at 13:07):It is the view you can from VIEW option in the menu bar.
ae 45 45 is azimuth and elevation value for the current view.
Mayank Goyal (Dec 03 2019 at 13:07):Thank you
Sahibpreet Kaur (Dec 03 2019 at 13:08):under the VIEW option you can see a bunch of views you can display your design in. Also, it has been explained in the tutorial.
Mayank Goyal (Dec 03 2019 at 13:10):Yes, I just tried to save a PNG image by running "rt -o lesson01.png" in the command window , but it didn't work
Mayank Goyal (Dec 03 2019 at 13:10):It was given in the task description
Savar Bhasin (Dec 03 2019 at 13:14):Can anyone tell me how to change the color of the text in LibreCAD
Sahibpreet Kaur (Dec 03 2019 at 13:15):@Mayank Goyal Yeah, it comes after you have drawn a design that comes after following the tutorial. So, basically you have to draw the designs given in each lesson and then use the command given in the task to save the image.
Sahibpreet Kaur (Dec 03 2019 at 13:15):Make sure to name the images based on the lessons you did.
Mayank Goyal (Dec 03 2019 at 13:16):OK , thank you so much
Sean (Dec 03 2019 at 13:22):Also noted in the task description, you can alternatively just run "rt" and make sure all the windows are in your screenshot
Minh Duc Le (Dec 03 2019 at 14:44):Hello everyone!
I have installed brlcad, but there is no bin folder in the build folder. Can anyone help me?
Jeffrey Liu (Dec 03 2019 at 14:48):Could you send a screenshot of the files that you see?
Minh Duc Le (Dec 03 2019 at 14:50):
Jeffrey Liu (Dec 03 2019 at 14:53):Have you compiled the project already?
Jeffrey Liu (Dec 03 2019 at 14:54):If you have, the bin directory should be located in either Debug or Release
Minh Duc Le (Dec 03 2019 at 15:03):I have just opened those folders, but there is no file named mged or archer. How can I run them?
pasted image
Jeffrey Liu (Dec 03 2019 at 15:05):Have you compiled the VS Solution yet?
Minh Duc Le (Dec 03 2019 at 15:06):How can I do that?
Jeffrey Liu (Dec 03 2019 at 15:08):So if you go back to the brlcad-build directory, you'll see a file called BRLCAD.sln. Open that and compile it (this should take a while), and I believe that depending on what you set (Debug or Release), one of the folders should have the correct files.
Jeffrey Liu (Dec 03 2019 at 15:11):Let me know if it works.
Minh Duc Le (Dec 03 2019 at 15:40):@Jeffrey Liu , It has just finished compiling. Here is what the bin folder looks like now.
pasted image
Jeffrey Liu (Dec 03 2019 at 15:46):Hm... I don't think there should be so many dll files (I think most of them should just be exe files), but I'm not really sure what happened. How did you compile it?
Jeffrey Liu (Dec 03 2019 at 15:47):Sorry I didn't mean that those dll files shouldn't be there, I meant that I believe there should be more exe files than dll files there.
Himanshu (Dec 03 2019 at 15:50):Just need some clarification on this task https://codein.withgoogle.com/tasks/5649945713967104/?sp-organization=4884012200361984&sp-categories=1&sp-search=c~2Fc%2B%2B
Himanshu (Dec 03 2019 at 15:51):Is this pointing to struct bu_rb_tree *palette; /* Pixel palette */
Himanshu (Dec 03 2019 at 15:52):Tasks says not to use bu_rb interference
Himanshu (Dec 03 2019 at 16:05):any clarification ?
Himanshu (Dec 03 2019 at 16:15):as per my thinking, this task wants to replace red-black tree algorithm into std::map as std::map has all the functionalities like insert(), erase(), clear() etc
BRL-CAD's IRC Bot (Dec 03 2019 at 16:37):Stragus@irc.freenode.net: There are many storage structures that can insert/delete items, the choice of red-black trees or whatever depends on the operations you have to do
BRL-CAD's IRC Bot (Dec 03 2019 at 16:38):Stragus@irc.freenode.net: A red-black tree has very different properties from a hash table like std::map, but I don't know the requirements for that particular case
Himanshu (Dec 03 2019 at 17:35):This is something like hash table or something
Daniel Rossberg (Dec 03 2019 at 18:11):as per my thinking, this task wants to replace red-black tree algorithm into std::map as std::map has all the functionalities like insert(), erase(), clear() etc
You are saying it here: Replace bu_rb_tree by std::map - with an int32_t as key.
What's the value type?
Daniel Rossberg (Dec 03 2019 at 18:16):@Minh Duc Le Did the compilation finished without errors?
Himanshu (Dec 03 2019 at 18:27):@Daniel Rossberg I will look into that as no. 3. For now I had chosen another debugging task
Daniel Rossberg (Dec 03 2019 at 18:29):Did you already compiled the experimental features?
Himanshu (Dec 03 2019 at 18:30):currently working on Test and fix single precision compilation
Himanshu (Dec 03 2019 at 18:30):changing double to float and checking if any errors or warnings
Himanshu (Dec 03 2019 at 18:31):Did you already compiled the experimental features?
nah
Himanshu (Dec 03 2019 at 18:34):btw I never used visual studio
Himanshu (Dec 03 2019 at 18:34):using vim
Himanshu (Dec 03 2019 at 18:35):is visual studio better?
Himanshu (Dec 03 2019 at 18:35):okay I will have a look into it
Daniel Rossberg (Dec 03 2019 at 18:35):There are easy programming tasks in the "experimental features", where you can learn how to change code, recompile it, and generate a patch file.
Himanshu (Dec 03 2019 at 18:36):There are easy programming tasks in the "experimental features", where you can learn how to change code, recompile it, and generate a patch file.
okay I will go though it
Daniel Rossberg (Dec 03 2019 at 18:37):is visual studio better?
It depends on which OS you work.
Daniel Rossberg (Dec 03 2019 at 18:37):There are easy programming tasks in the "experimental features", where you can learn how to change code, recompile it, and generate a patch file.
okay I will go though it
There is an own task for compiling the experimental features.
Himanshu (Dec 03 2019 at 18:37):thanks for info @Daniel Rossberg :)
Daniel Rossberg (Dec 03 2019 at 18:39):And then, you can do the "Remove throw statements" tasks.
Himanshu (Dec 03 2019 at 18:40):looks like it goes through this
Himanshu (Dec 03 2019 at 18:40):Compile BRL-CAD's experimental features
Himanshu (Dec 03 2019 at 18:41):and then onward remove throw statements
Himanshu (Dec 03 2019 at 18:42):btw what's the difference between default build and release build mentioned in http://brlcad.org/wiki/Building_from_SVN#Configure_the_build_system_with_CMake ?
Erik (Dec 03 2019 at 18:50):hey Erik :)
Hi, is there something I can help with?
Erik (Dec 03 2019 at 18:51):default build has some optimizations turned off and some debugging turned on, release is "for performance", do a default build
Daniel Rossberg (Dec 03 2019 at 18:52):CMake usually detects already existing libraries on you system and uses them instead of their versions provided with the BRL-CAD source code (usually in the src/other directory). DBRLCAD_BUNDLED_LIBS=ON demands to use always the version which comes with the BRL-CAD source code.
There are usually two main build types: Debug and Release. Debug contains additional code/data to match it with the source code. I.e., it can be said which code part belongs to which source code line and what the variables' values are.
The release build is a usually speed optimized build with no debug information and variables often often don't have a memory address, because they live in processor registers only (if possible).
Erik (Dec 03 2019 at 18:53):(Easy bugs in debug builds can very easily become difficult bugs in release mode due to compiler optimization methods, all ya'll should be avoiding release unless you know what you're doing)
Himanshu (Dec 03 2019 at 19:07):thanks for info @Erik @Daniel Rossberg
Jeffrey Liu (Dec 04 2019 at 02:43):Hey, I just SVN Updated to the latest revision (r74417) and tried to remake/recompile the source, but for some reason there's a couple issues now; it says that 124 projects failed and my bin directory ends up missing a lot of executables. Has anyone else encountered this?
Jeffrey Liu (Dec 04 2019 at 02:48):Reading through the build log, one of the first errors that occurs is error C2039: 'map': is not a member of 'std' in debug2c.cxx
Sean (Dec 04 2019 at 02:54):The release build is a usually speed optimized build with no debug information and variables often often don't have a memory address, because they live in processor registers only (if possible).
We actually break convention there as RELEASE build retains debug symbols, but it is also highly optimized (so -O3 plus other flags). In testing, keeping debug symbols has typically been found to have a negligible impact on performance, but having the symbols for debugging has been invaluable.
Sean (Dec 04 2019 at 02:56):any clarification ?
@Himanshu Sekhar Nayak not sure what you're asking beyond what's written in the task. The goal is simply to not use the bu_rb calls like that bu_rb_tree struct. You can otherwise implement the tool however you want and use whatever you want so long as it outputs correctly.
BRL-CAD's IRC Bot (Dec 04 2019 at 04:06):ezzieygu1wuf@irc.freenode.net: I literally just copied the svn trunk and compiled today
BRL-CAD's IRC Bot (Dec 04 2019 at 04:06):ezzieygu1wuf@irc.freenode.net: only issue was tcl/tk mismatch, switched from 'system' to 'bundled' and it compiled fine
Sean (Dec 04 2019 at 04:13):excellent
Sean (Dec 04 2019 at 04:14):Reading through the build log, one of the first errors that occurs is error C2039: 'map': is not a member of 'std' in debug2c.cxx
@Jeffrey Liu yeah, that was recent change. I have a fix I'm about to commit. Basically, there's a #include <map> missing from a couple files that didn't exhibit as an error for the dev that did some commits recently.
Jeffrey Liu (Dec 04 2019 at 04:16):I manually included the statements in the two files where it was missing and I'm currently compiling, which seems to be working at the moment.
Jeffrey Liu (Dec 04 2019 at 04:17):But thanks for letting me know that it wasn't just something wrong with just my setup, I was really confused.
Sean (Dec 04 2019 at 04:18):You code long enough with others and cross-platform issues like that start to become very obvious. ;)
BRL-CAD's IRC Bot (Dec 05 2019 at 02:49):yukonbob@irc.freenode.net: hello #brlcad
Himanshu (Dec 05 2019 at 06:47):how's going @Jeffrey Liu ?
Jeffrey Liu (Dec 05 2019 at 06:48):I'm good, how about you?
Himanshu (Dec 05 2019 at 06:48):yeah me too I saw you are gonna work on count pix
Himanshu (Dec 05 2019 at 06:49):sounds great
Himanshu (Dec 05 2019 at 06:49)::)
Jeffrey Liu (Dec 05 2019 at 06:49):Yep, I think I'm close to finishing it. What are you working on?
Himanshu (Dec 05 2019 at 06:50):I am working on Compile BRL-CAD's experimental features
Himanshu (Dec 05 2019 at 06:50):a source dir rt^3
Jeffrey Liu (Dec 05 2019 at 06:50):I see, how's it going for you?
Chiranjiv Singh Malhi (Dec 05 2019 at 06:51):Hi
Himanshu (Dec 05 2019 at 06:51):Hey
Himanshu (Dec 05 2019 at 06:52):@Jeffrey Liu got the build environment ready but I can't find coreinterface, printTitle, embeddedlua, and hellobrlcad targets
Himanshu (Dec 05 2019 at 06:53):I think after compilation they should be present in bin dir but I can't find them.
Jeffrey Liu (Dec 05 2019 at 06:56):Hm, unfortunately I probably can't offer much assistance because I haven't done that task yet, but were there any compilation errors?
Himanshu (Dec 05 2019 at 06:56):many compilation errors but I resolved them and got the build environment ready
Himanshu (Dec 05 2019 at 06:56):but can't find those files yet
Jeffrey Liu (Dec 05 2019 at 06:58):Looking at the task, I believe the targets are referring to the build targets and not executables.
Himanshu (Dec 05 2019 at 07:01):btw bin dir contains all the executables right ? @Jeffrey Liu
Jeffrey Liu (Dec 05 2019 at 07:02):Afaik, it should.
Chiranjiv Singh Malhi (Dec 05 2019 at 07:39):Hi. I wanted to know about converting model from one extension to another.
Erik (Dec 05 2019 at 12:02):@Chiranjiv Singh Malhi BRL-CAD only converts to-from it's native .g format, there are many binaries for conversion, g-stl exports an STL file, stl-g imports stl, ... many other formats with similar names (g-obj, g-step, ...)
The src/conv/ directories has the source code for all the converters
Chiranjiv Singh Malhi (Dec 05 2019 at 12:07):@Erik alright got it , thanks .
BRL-CAD's IRC Bot (Dec 06 2019 at 02:54):starseeker@irc.freenode.net: brlcad: a quick experiment makes me think the C++ build will be less trivial than I'd hoped - should I just generate a list of the char * const assignments? Those are probably the lowest hanging fruit
Sean (Dec 06 2019 at 16:15):@starseeker we can certainly try. I agree that just having them tackle the random errors that are going to result is probably not going to be effective. when I saw your e-mail, I noticed right away that the proper fix was probably to propagate const, but doing that to routines gets really hairy really fast. the functions that take static strings are almost certainly already ones that can be made const, but they often call other functions that may or may not be constified, and your average gci isn't going to have a recipe to know when to dup and free.
Sean (Dec 06 2019 at 16:16):otherwise, best option for a task would have been what you already just did -- turn it on and submit a build report of all the errors.
BRL-CAD's IRC Bot (Dec 06 2019 at 22:15):yukonbob@irc.freenode.net: hello #brlcad
Sean (Dec 06 2019 at 22:20):howdy!
scorp08 (Dec 07 2019 at 09:38):Hello all
@Sean I was just wondering what is the purpose of BU_BITTEST ? To check bit list ?
Jeffrey Liu (Dec 07 2019 at 19:05):@Chiranjiv Singh Malhi I believe that within the command, your next argument must specify which primitives/combinations within the database you want to convert.
Sean (Dec 08 2019 at 19:47):@scorp08 it returns truthfully whether a given bit in a bitset is set

Mayank Goyal (Dec 09 2019 at 10:34):I was on the task where I had to convert .g file to .bj file
Mayank Goyal (Dec 09 2019 at 11:30):*.obj file
Mayank Goyal (Dec 09 2019 at 11:32):I tried this code (g-wave [options] input.g object(s)) but it didn't work.
Chiranjiv Singh Malhi (Dec 09 2019 at 11:40):@Mayank Goyal try the code
g-obj -o output.obj input.obj object_name
Mayank Goyal (Dec 09 2019 at 11:41):I will surely try
Mayank Goyal (Dec 09 2019 at 11:41):thanks
Mayank Goyal (Dec 09 2019 at 11:44):
Mayank Goyal (Dec 09 2019 at 11:44):It is showing invalid command
Chiranjiv Singh Malhi (Dec 09 2019 at 11:45):Sorry typing error instead of input.obj it should be input.g
Chiranjiv Singh Malhi (Dec 09 2019 at 11:46):And
Chiranjiv Singh Malhi (Dec 09 2019 at 11:46):You don't convert in mged
Chiranjiv Singh Malhi (Dec 09 2019 at 11:47):(deleted)
Chiranjiv Singh Malhi (Dec 09 2019 at 11:48):(deleted)
Chiranjiv Singh Malhi (Dec 09 2019 at 11:48):Read this doc , it will help you
Chiranjiv Singh Malhi (Dec 09 2019 at 11:50): Mayank Goyal (Dec 09 2019 at 11:54):okay :+1:
Mayank Goyal (Dec 09 2019 at 11:54):(deleted)
Mayank Goyal (Dec 09 2019 at 12:01):g-obj.PNG can this be used
Jeffrey Liu (Dec 09 2019 at 12:30):Thank you for the response @Sean ! I went with a 1001x1001 grid. Sorry to bother you again, but I had one more question for the task (hopefully the last one): seeing that I am only printing a black for miss and a white for hit, could I simply just have the hit/miss callbacks return a certain value without doing anything else?
BRL-CAD's IRC Bot (Dec 09 2019 at 15:02):starseeker@irc.freenode.net: epileg: define "major" release
BRL-CAD's IRC Bot (Dec 09 2019 at 15:04):starseeker@irc.freenode.net: epileg: we just tagged a patch release, and a minor release (incrementing the middle version number) will come when some combination of features and improvements warrants it
BRL-CAD's IRC Bot (Dec 09 2019 at 15:04):starseeker@irc.freenode.net: a "major" release (updating from 7.x to 8.x) isn't in the works anytime soon
BRL-CAD's IRC Bot (Dec 09 2019 at 15:13):epileg@irc.freenode.net: sorry, minor release
BRL-CAD's IRC Bot (Dec 09 2019 at 15:14):starseeker@irc.freenode.net: Probably safe to predict one within the next six months - there are a couple features in the works that would warrant it - but can't pin down more closely than that right now
Mohtashim Monowar (Dec 09 2019 at 15:24):I can't find LibreCAD version 3 for claim the tasks of LibreCAD version 3. Where I can find LibreCAD version 3 to download?
BRL-CAD's IRC Bot (Dec 09 2019 at 15:25):epileg@irc.freenode.net: ok, thank starseeker. I just asked this because there is a minor release every year, that's all
Jeffrey Liu (Dec 09 2019 at 15:26):@Mohtashim Monowar There should be a task relating to building LibreCAD. It is probably the beginning of the LibreCAD task set, so I would recommend doing that first before moving on to other related tasks.
Mayank Goyal (Dec 09 2019 at 15:28):I can't find LibreCAD version 3 for claim the tasks of LibreCAD version 3. Where I can find LibreCAD version 3 to download?
You can visit this website https://github.com/LibreCAD/LibreCAD_3
Sean (Dec 09 2019 at 21:52):Thank you for the response Sean ! I went with a 1001x1001 grid. Sorry to bother you again, but I had one more question for the task (hopefully the last one): seeing that I am only printing a black for miss and a white for hit, could I simply just have the hit/miss callbacks return a certain value without doing anything else?
Questions are never a bother. :) Absolutely you can do whatever you want in a callback. Depending on what you need to do, you may need some book-keeping method to keep track of results, but the callback return value itself will be in the a_return field of the application struct.
Sean (Dec 09 2019 at 21:58):I tried this code (g-wave [options] input.g object(s)) but it didn't work.
@Mayank Goyal Where did you learn about g-wave? That converter was renamed in 2005..... You may have installed an ancient version. (and yes, you run the converters outside of mged).
Jeffrey Liu (Dec 09 2019 at 22:26):Thank you for your response :) I just figured that the printing was causing a huge bottleneck problem because the program was taking much longer with them included. In this case, it seems like the default int return type worked fine - I just needed to adjust the return values to indicate a hit or a miss.
Kartik kumar (Dec 10 2019 at 04:28):Hi @Mohtashim Monowar Thanks for showing interest.
This is the initial task you should try: https://codein.withgoogle.com/dashboard/tasks/5076591336488960/
Once you are done with it , you can do all tasks related to LibreCAD V3. It would be exciting
And i suggest you to join Zulip channel of LibreCAD: https://librecad.zulipchat.com/login/

i cant use vim efficiently so i use atom
Thusal Ranawaka (Dec 16 2019 at 14:38):in BRLCAD rendering means ray trace?
Sumagna Das (Dec 16 2019 at 14:39):yea
Sumagna Das (Dec 16 2019 at 14:39):i think so
Thusal Ranawaka (Dec 16 2019 at 14:42):when pressing ctrl and dragging downwards what happens
Sumagna Das (Dec 16 2019 at 14:42):it zooms out
Sumagna Das (Dec 16 2019 at 14:42):but it will take some time
Sumagna Das (Dec 16 2019 at 14:43):do it for some time and you will see the sphere n pink color
Sumagna Das (Dec 16 2019 at 14:43):you need to assign a material to the front side but do it afterwards
Thusal Ranawaka (Dec 16 2019 at 14:51):In assign material option what should i type on the filter
Sumagna Das (Dec 16 2019 at 14:51):you have to make a material
Sumagna Das (Dec 16 2019 at 14:51):first create a color
Sumagna Das (Dec 16 2019 at 14:52):in assembly group
Thusal Ranawaka (Dec 16 2019 at 14:52):and type material1 on the filter
Sumagna Das (Dec 16 2019 at 14:52):you have a material created?
Thusal Ranawaka (Dec 16 2019 at 14:54):i have select create generic material option
Sumagna Das (Dec 16 2019 at 14:55):there change the value of color which is 0 0 0
Sumagna Das (Dec 16 2019 at 14:56):change it to 0 1 2 or something but dont change the first zero
Sumagna Das (Dec 16 2019 at 15:09):hey thusal, done?
Thusal Ranawaka (Dec 16 2019 at 15:10):yes
Thusal Ranawaka (Dec 16 2019 at 15:10):50%
Thusal Ranawaka (Dec 16 2019 at 15:12):when i assign a material and render the pink goes to black colour
Sumagna Das (Dec 16 2019 at 15:12):you have to add a light now
Sumagna Das (Dec 16 2019 at 15:12):which should be directional light
Thusal Ranawaka (Dec 16 2019 at 15:13):then
Sumagna Das (Dec 16 2019 at 15:25):press F5 again
Thusal Ranawaka (Dec 16 2019 at 15:26):okay i got a white sphere now i sending it for review
Sumagna Das (Dec 16 2019 at 15:27):ok
Thusal Ranawaka (Dec 16 2019 at 15:27):thanks for your help again
Sumagna Das (Dec 16 2019 at 15:27):i have sent it for review but still not reviewed
Thusal Ranawaka (Dec 16 2019 at 15:33):Sumagna can you send a screenshot or the URL of your dashboard
Thusal Ranawaka (Dec 16 2019 at 15:39):Bye guys
scorp08 (Dec 16 2019 at 16:24):@Sean Is it a bad idea to leave semaphores in shootrays_parallel and directly feed rt_shootray to bu_parallel ?
Sumagna Das (Dec 16 2019 at 17:42):@Sean how to build and compile rtexample.c?
Sumagna Das (Dec 16 2019 at 17:43):in the same way, i will also build and compile the c++ program for appleseed #2
Daniel Rossberg (Dec 16 2019 at 18:39):You need to set-up your build environment such that it finds BRL-CAD's header files and libraries. You can do this by cloning a project which is doing this, for example from the brlcad or rt^3 repository.
Or, you do it by yourself and set the paths and libraries in your CMakeLists.txt, for exmple.
Sumagna Das (Dec 16 2019 at 18:54):ok but i csnt do it still
Daniel Rossberg (Dec 16 2019 at 18:56):Then, what are you doing?
Daniel Rossberg (Dec 16 2019 at 18:59):Remember, I can't see, hear, smell, etc., what you are doing. All I have is this chat. I've no idea what you've tried, typed, etc..
Sumagna Das (Dec 16 2019 at 19:00):i changed the cmakelists.txt inside src/rt folder of brlcad (not rt^3)
Sumagna Das (Dec 16 2019 at 19:00):and it gave me errors so i did a clean download again
Daniel Rossberg (Dec 16 2019 at 19:00):How? (post a patch file with your changes)
Sumagna Das (Dec 16 2019 at 19:01):i am gonna try it again
Sumagna Das (Dec 16 2019 at 19:01):i deleted it(sorry)
Daniel Rossberg (Dec 16 2019 at 19:05):Be as precise as possible. I could write "you did it wrong, if you would do it correctly it would work". This would be totally correct, but also absolutely not helpful.
Therefore, provide as much information as possible such that I can point you into the right direction.
Sumagna Das (Dec 16 2019 at 19:07):ok
Sumagna Das (Dec 16 2019 at 19:07):my internet is not working that well
Sumagna Das (Dec 16 2019 at 19:09):so the download is very slow
Daniel Rossberg (Dec 16 2019 at 19:12):(Now idea why you have to download the sources again.)
Sumagna Das (Dec 16 2019 at 19:13):I deleted the whole thing
Sumagna Das (Dec 16 2019 at 19:13)::neutral:
Daniel Rossberg (Dec 16 2019 at 19:14):All of it? You are working with subversion. There you can revert your changes and restore the original sources.
Sumagna Das (Dec 16 2019 at 19:24):I forgot in the hustle and bustle around me
Sumagna Das (Dec 16 2019 at 19:38):daniel i got this error while make-ing brlcad
Sumagna Das (Dec 16 2019 at 19:39):
Sumagna Das (Dec 16 2019 at 19:40):this is is the error
Sumagna Das (Dec 16 2019 at 19:40):i did nothing
Sumagna Das (Dec 16 2019 at 19:40):it was a clean download
Sumagna Das (Dec 16 2019 at 19:51):hello lord
Daniel Rossberg (Dec 16 2019 at 20:01):How does Unit.cpp look? Damaged?
Sumagna Das (Dec 16 2019 at 20:02):It's now building all right
Sumagna Das (Dec 16 2019 at 20:02):I think
Sumagna Das (Dec 16 2019 at 20:03):It haven't got to unit.cpp.o yet
Sumagna Das (Dec 16 2019 at 20:03):It's right now at 'p' files
Sumagna Das (Dec 16 2019 at 20:03):It's so late
Daniel Rossberg (Dec 16 2019 at 20:04):It's okay to make a break an go to sleep.
Sumagna Das (Dec 16 2019 at 20:09):It's okay and building right
Sumagna Das (Dec 16 2019 at 20:09):Thinking about letting it happen during the night
Sean (Dec 17 2019 at 06:44):Sean Is it a bad idea to leave semaphores in shootrays_parallel and directly feed rt_shootray to bu_parallel ?
as with most performance-related questions like that, the answer is a huge "it depends"
Sean (Dec 17 2019 at 06:46):in general, i wouldn't leave them in and try to create an impl that doesn't rely on synchronization, but then you also won't likely see any performance implication with most use cases that come to mind.
Sahil Garg (Dec 17 2019 at 10:33):I was unable to find this any config.example.json but found a config file in the .git folder and it states:
[core]

bare = false
logallrefupdates = true
[remote "origin"]
url = https://github.com/BRL-CAD/OGV-meteor.git
fetch = +refs/heads/:refs/remotes/origin/
[branch "development"]

How can I edit it? Also I found this in the readme!
Move config.example.json to config.json and write admin password there.

Sumagna Das (Dec 17 2019 at 16:32):What task are u working on now?
Himanshu (Dec 17 2019 at 18:15):Hey @Daniel Rossberg How I can determine the value of return statement ?
Himanshu (Dec 17 2019 at 18:15):here is an example like this
Himanshu (Dec 17 2019 at 18:15):template<_GetObject getObject> static int Name
(
lua_State* luaState
) {
BRLCAD::Object& object = (*getObject)(luaState, 1);
lua_pushstring(luaState, object.Name());
return 1;
}
Himanshu (Dec 17 2019 at 18:16):Here it is returning 1
Himanshu (Dec 17 2019 at 18:28):btw I got a reference manual to bind it http://www.lua.org/manual/5.1/manual.html#3
Sumagna Das (Dec 17 2019 at 18:35):Hey Himanshu
Sumagna Das (Dec 17 2019 at 18:36):What series of tasks are you working on?
Himanshu (Dec 17 2019 at 18:40):btw I found a class here class BRLCAD_COREINTERFACE_EXPORT AttributeIterator
Himanshu (Dec 17 2019 at 18:40):is that what you are pointing to ?
Himanshu (Dec 17 2019 at 18:42):@Daniel Rossberg If I am correct than I have to only do the work on Object atrributes methods ?
Himanshu (Dec 17 2019 at 18:43):Hey Himanshu

Chiranjiv Singh Malhi (Dec 17 2019 at 18:45):I used this command
Daniel Rossberg (Dec 17 2019 at 18:48):Hey Daniel Rossberg How I can determine the value of
returnstatement ?
The function returns the number of return values. The values are put on the stack. In your example, it returns one string. lua_pushstring() pushes the value on top of the stack and return 1; signals that the function put one value as a function return on the stack.
Sumagna Das (Dec 17 2019 at 18:49):Hey Daniel how's it going?
Daniel Rossberg (Dec 17 2019 at 18:49):Daniel Rossberg If I am correct than I have to only do the work on
Object atrributes methods?
No, all but the attribute methods. I.e., only the simple ones.
Daniel Rossberg (Dec 17 2019 at 18:52):Hey can anyone help me whenever I convert from iges to g I never get any geometry
It looks like the iges geometry doesn't contain any solid (3D element).
Sumagna Das (Dec 17 2019 at 18:53):Which task are you on @Chiranjiv Singh Malhi ?
Chiranjiv Singh Malhi (Dec 17 2019 at 18:55):Importing from freecad

Sean (Dec 18 2019 at 05:03):in BRLCAD rendering means ray trace?
yes, rendering typically means ray tracing
Sean (Dec 18 2019 at 05:06):Sean Is it a bad idea to leave semaphores in shootrays_parallel and directly feed rt_shootray to bu_parallel ?
@scorp08 as with most things "it depends". In general, it's not a terrible idea if done right.. It just might slow things down a little bit. However, what your'e suggesting is essentially what rt_shootrays() is doing (without a need for additional semaphores)
Sean (Dec 18 2019 at 05:07):Sean how to build and compile rtexample.c?
See the wiki page on it for an example, but the answer very much depends on your operating system. It is already part of the BRL-CAD build, though. It's just not installed (see path/to/build/src/rt/rtexample)
Thusal Ranawaka (Dec 18 2019 at 06:06):In Appleseed#2 task it shows that there is a task for download and install BRL CAD from source but I cannot find that task.
Sean (Dec 18 2019 at 06:22):@Thusal Ranawaka there is a task to compile brl-cad from source
Sean (Dec 18 2019 at 06:22):how are you searching for it?
Thusal Ranawaka (Dec 18 2019 at 06:38):I think so
Sean (Dec 18 2019 at 07:27):I think so
what? I asked how are you searching for it. what method or search terms are you using?
