| 00:24.06 | pacman87 | hi yukonbob |
| 00:24.15 | yukonbob | what's happening, pacman87? |
| 00:24.24 | pacman87 | um, not my raytracing |
| 00:24.36 | yukonbob | feh... |
| 00:24.44 | yukonbob | try solidworks ;) |
| 00:24.59 | pacman87 | i mean my primitive's raytracing |
| 00:25.06 | yukonbob | knows -- is joking |
| 00:25.14 | pacman87 | i dont thing solidworks does hyperboloids, anyway |
| 00:25.26 | yukonbob | hits google |
| 00:26.06 | yukonbob | my Net connection is working about as well as your raytracing :P |

| 00:46.39 | pacman87 | progress: https://webspace.utexas.edu/trv82/www/hyp_rt3.png |
| 00:46.51 | pacman87 | still not sure why the bottom plate is showing, though |

| 01:36.16 | brlcad | pacman87: woot, nice progress! |
| 01:36.29 | brlcad | my guess would be sort order |
| 01:36.45 | brlcad | the in-out segment points you add to the result should be sorted |
| 01:37.40 | brlcad | if you have the segment inverted so you present the back-facing bottom plate exit point before the side-wall entry point, you could see that kind of effect |
| 01:38.33 | brlcad | course could be something wrong with the middle surface.. those normals are whack |
| 01:46.54 | andrecastelo | hey brlcad .. the rt applications consist of view[app].c + worker.c + do.c + opt.c + main.c, right? what functions are specific to the view file, in this case viewmlt.c? i've reorganized the declarations and the mlt project file to be compliant with this system |
| 01:50.18 | brlcad | andrecastelo: there's about a dozen view*.c example rt apps that show the various call-backs you have to hook |
| 01:51.27 | andrecastelo | brlcad: ok, I'll look for them, thanks :) |
| 01:53.57 | brlcad | I believe a lot of it is covered in http://brlcad.org/w/images/3/3d/Application_Development.pdf too |
| 02:10.02 | andrecastelo | brlcad: yeah but it kind of confused me, because it has main() and etc. But i already solved the problem :D |
| 02:13.43 | brlcad | yeah, the part that is relevant is the "RTUIF" that it refers to , the view callbacks it refers to |
| 02:13.56 | brlcad | those are what are in your viewmlt.c file |
| 02:14.44 | brlcad | the tutorial starts from one level deeper, and also describes how to implement the rt front-end in addition to view interface |

| 02:18.57 | CIA-21 | BRL-CAD: Merged definitions from mlt_defs.h into viewmlt.c. Added functions to make |
| 02:18.57 | CIA-21 | BRL-CAD: viewmlt.c a rt compatible application. Added missing files (worker.c, do.c, |
| 02:18.57 | CIA-21 | BRL-CAD: main.c and opt.c) to win32-msvc9/rtmlt/rtmlt.vcproj. It should build correctly |
| 02:18.57 | CIA-21 | BRL-CAD: now. |
| 02:19.11 | andrecastelo | mlt_defs.h is useless now :S |
| 02:20.38 | brlcad | so remove it? |
| 02:20.51 | brlcad | nothing wrong with adding/removing as needed as it evolves :) |
| 02:20.58 | brlcad | don't forget the Makefile.am if you remove it ;) |

| 02:51.53 | *** join/#brlcad Twingy (n=justin@74.92.144.217) | |
| 03:15.35 | brlcad | andrecastelo: heh, nope -- you can never go back! |
| 03:15.48 | andrecastelo | :O |
| 03:16.40 | brlcad | if you really really want to leave a note, make a ws commit and annotate in the commit message that it is for r31289, etc |
| 03:16.41 | andrecastelo | ws commit? |
| 03:16.46 | brlcad | ~ws |
| 03:16.49 | ibot | ws is probably short for workstation. White Space, or the country code for Western Samoa |
| 03:18.10 | andrecastelo | ok, i'll do a western samoa commit ;) |
| 03:20.18 | brlcad | :) |

| 03:30.26 | poolio | brlcad: so is src/librt restructured as you wanted now or is there still more? |
| 03:42.32 | pacman87 | so i fixed my bottom plate, but the normals are definately off |

| 12:36.06 | brlcad | new primitives are always exciting :) |
| 12:36.56 | brlcad | howdy mafm, how goes it? |
| 12:40.19 | mafm | tired, but other than that OK :) |
| 12:53.08 | mafm | do you support "make distclean"? |
| 12:53.26 | mafm | it's starting to configure things before removing them |
| 13:05.27 | brlcad | yes, of course |
| 13:06.09 | brlcad | whether it has to configure before cleaning depends on the dependency tracking and edit states of files (timestamps) |
| 13:06.39 | brlcad | if you did an svn update, it would have to regenerate and rerun configure before it could perform the clean |
| 13:07.33 | brlcad | automake design, not our doing |
| 13:07.38 | alex_joni | that "bites" sometimes.. it's always best to do an distclean before updating |
| 13:08.22 | alex_joni | (if there was a long period of time since the last update.. and lots of infrastructure changes) |
| 13:09.25 | brlcad | the faster more general rule I usually suggest is if you see configure.ac or any Makefile.am get updated, run: sh autogen.sh && ./configure --enable-all && make clean && make |
| 13:09.55 | brlcad | that'll generally complete more quickly and reliably than trying to force a distclean, and should give the same result |
| 13:10.19 | brlcad | since distclean can actually fail under some update/edit situations |
| 13:15.48 | brlcad | once you get more familiar with what the Makefile's are doing and how the timestamp updates work, you can get away with the localized depcomp rebuilds and automatic reconfigurate |
| 13:16.06 | brlcad | but few get to the level of understanding ;) |
| 13:16.32 | mafm | not very likely, yep :D |
| 13:16.41 | mafm | was cmake considered? |
| 13:16.45 | brlcad | sure |
| 13:16.55 | brlcad | it's used for some of the windows build |
| 13:17.13 | brlcad | to redo the entire build system with it though is a pretty big effort |
| 13:18.06 | ``Erik | cmake adds a new end user dependancy, no? |
| 13:18.14 | brlcad | with pretty minimal payoff -- what we have works and works rather well, robust, familiar, etc, just painful to the autotool newbies (which tend to be in the minority) |
| 13:18.32 | brlcad | yeah, it's not nearly as prevalent |
| 13:19.04 | mafm | I meant mostly as it seems to reduce compilation times, not sure if that is an issue for devels |
| 13:19.10 | ``Erik | yeah, I think we have two "guru" grade automake weenies (if I'm allowed to claim that for myself, heh) who'll fix the newbs mistakes if they're hacking |
| 13:19.24 | brlcad | nah, that's a petty benefit frankly |
| 13:19.31 | ``Erik | good structuring of an automake system will be pretty damn quick |
| 13:19.33 | brlcad | compilation time is dominated by the machine |
| 13:19.52 | ``Erik | I'm tempted to flatten the src/adrt directory for the half second speed boost O>o |
| 13:19.53 | ``Erik | O.o |
| 13:20.26 | ``Erik | (also; we have "make fast" which speeds things up a fair amount... gmake -sj13 fast) |
| 13:21.20 | mafm | well dunno, but it takes something like 5 minutes to run "configure" on my system |
| 13:21.37 | ``Erik | what is your system? the only thing I've seen close to that slow is windows O.o |
| 13:21.38 | brlcad | we'd have to do those same checks with cmake |
| 13:21.43 | brlcad | that problem doesn't go away |
| 13:21.55 | mafm | amd64, 1gb ram, 2 years old |
| 13:21.57 | brlcad | it's just not called a "configure" script |
| 13:22.29 | ``Erik | OS is a bigger impact, I think |
| 13:22.59 | ``Erik | windows is ass slow, fbsd is smoking fast, linux is almost as fast as fbsd, mac is somewhere between bsd/linux and windows |
| 13:23.04 | mafm | Debian GNU/Linux, random :P version |
| 13:23.38 | brlcad | it's I/O intense, if you have slow OS or slow disks, it'll be teh suck |
| 13:23.39 | ``Erik | weird, does it have any obvious stall points? or are you feeding it funny options? mebbe if you "export CFLAGS=-pipe" ? |
| 13:24.47 | brlcad | suspects a bit of exaggeration too, probably closer to 3 minutes on that system |
| 13:25.18 | brlcad | it reports the time, how long exactly? |
| 13:25.21 | ``Erik | "time sh configure" :) |
| 13:25.29 | brlcad | it's in the summary |

| 13:31.39 | mafm | I'm not doing anything special... it might not even be 5 minutes but instead 2, dunno |
| 13:32.26 | mafm | some of the projects where I worked recommended a full clean build every morning, and things like these are time-consuming, but that's not the case for all projects of course ;) |
| 13:32.29 | brlcad | there was another good one yesterday that dealt with extracting an implicit model from CT scan data for capturing blood vessels, neural connectivity, and other "tube networks" from a friend down at Texas A&M |

| 13:33.08 | brlcad | mafm: those instructions are recommended only to those that don't learn how the tools work but just use them as tools |
| 13:33.17 | ``Erik | that's why I tend to be conservative about changing or adding directories :) |
| 13:33.24 | brlcad | you can get away with much much faster rebuild times if/when you know when you really need to do what |

| 14:07.27 | ``Erik | there we go :) |
| 14:10.16 | mafm | louipc: make is in the making |
| 14:10.47 | louipc | holy anteater |
| 14:13.11 | ``Erik | organic debugger :) |
| 14:13.31 | mafm | ``Erik: I'm not worrying about that... I just asked if you had though about cmake or something similar alternative, for me it has a lot of advantages but that's not the point :) |
| 14:13.42 | mafm | and I'm running the time tests just because you asked |
| 14:15.25 | ``Erik | we've talked about cmake, a couple other "new" build systems, if you check out an older version, it uses one called "cake", but automake was picked up because it was better than cake for handling diverse platforms with minimal developer concern, ubiquitous and "standard", and we had solid knowledge of it *shrug* BRL-CAD only went auto* 4.5 years ago, converting it was my second task :) |
| 14:20.10 | mafm | I see |
| 14:27.48 | mafm | same old error :S http://rafb.net/p/8K7VU536.html |
| 14:28.56 | ``Erik | sh configure --enable-all --enable-optimized --prefix=/place/it/goes |
| 14:29.43 | brlcad | the refree error is not fixed without --enable-all yet |
| 14:29.53 | ``Erik | afaik, the issue is with funky cpp paths, it's picking up $(top_srcdir)/src/other/tcl/generic/regex.h when it SHOULD be getting /usr/include/regex.h |
| 14:40.57 | brlcad | mafm: yeah, I'd agree that it has several advantages, just performances is a minor one in the big scheme of things .. the biggest is a unified build environment that spans to windows |
| 14:41.47 | brlcad | i wouldn't mind cmake if someone actually fully duplicated our current build system in it .. but I just don't see that happening anytime soon, it'd be weeks of full-time effort if not more |
| 14:42.14 | mafm | same error, maybe I should make clean before reconfiguring with --enable-all? |
| 14:42.26 | brlcad | yeah, have to make clean |
| 14:42.50 | brlcad | Tcl_ReFree is an unresolved symbol.. meaning you have a .o object file somewhere with references to it |
| 14:43.09 | brlcad | so just running make again doesn't invalidate that .o |
| 14:43.14 | ``Erik | (if you know which files, you can just remove the specific .o and .lo files, but it's easier to just make clean) |
| 14:43.35 | brlcad | from make's perspective, there's nothing to do |
| 14:45.33 | mafm | it's librt, but after removing it complained about the file not being present, so I just issued the make clean |
| 14:46.14 | brlcad | that all boils down to learning what the tools are doing :) |
| 14:46.25 | brlcad | there actually is deterministic behavior, but it takes a while to learn the tools |

| 17:49.00 | CIA-21 | BRL-CAD: 03brlcad * r31295 10/brlcad/trunk/src/adrt/adrt.h: screw the 'version year'? how about just say what adrt means |

| 18:03.59 | starseeker | of the bug? |
| 18:04.01 | starseeker | can do... |
| 18:05.41 | brlcad | finally! .. found a way to reproduce the _TclReFree error from here for non-enable-all |
| 18:06.46 | mafm | w00t |
| 18:09.22 | starseeker | http://pastebin.bzflag.bz/d64313679 |
| 18:09.36 | starseeker | that's the first issue... |
| 18:09.48 | starseeker | the second didn't reproduce, so maybe it's not an issue after all... |
| 18:10.06 | brlcad | you mean the "file test.cs is" ? |
| 18:10.12 | starseeker | yep |
| 18:10.20 | starseeker | it ate the last charater |
| 18:10.20 | brlcad | off-by-one somewhere |
| 18:10.28 | starseeker | oh, it gets better |
| 18:10.32 | ``Erik | <-- pats his belly |
| 18:10.34 | brlcad | probably strcpy |
| 18:10.41 | starseeker | if you type dest default (no space) you get back stdout |
| 18:10.44 | brlcad | er strlcpy |
| 18:11.12 | starseeker | if you do it WITH the space, you get a file called default |
| 18:11.54 | brlcad | same problem |
| 18:11.56 | starseeker | could it be the original authors intended that you would have to have a space after a name? |
| 18:12.17 | starseeker | thought dest default without space would create a file called defaul |
| 18:12.28 | brlcad | default == defaul vs "default " == default |
| 18:12.43 | brlcad | yeah, so it's probably a copy happening between those two checks |
| 18:12.43 | starseeker | but default doesn't == defaul |
| 18:12.48 | starseeker | it equals stdout |
| 18:13.06 | brlcad | so it does the strcmp before it gets trimmed |
| 18:13.13 | starseeker | ah |
| 18:13.31 | starseeker | digs a bit... |
| 18:13.36 | brlcad | otherwise, no .. no way needing a space was intended |
| 18:13.59 | brlcad | in face the command interpreter should trim all whitespace |
| 18:14.07 | brlcad | (should but probably doesn't) |
| 18:15.05 | prasad1 | brlcad, where are u? |

| 18:24.43 | brlcad | (which is what I'm currently working on) |
| 18:24.55 | starseeker | sweeet |
| 18:25.57 | brlcad | will need a few days to get through just the top half-dozen most interesting/useful papers |

| 18:30.10 | CIA-21 | BRL-CAD: 03starseeker * r31297 10/brlcad/trunk/src/nirt/parse_fmt.c: nirt's dest command was chopping off the last character in the filename string |
| 18:30.13 | starseeker | got it |
| 18:30.33 | starseeker | looks like it isn't trimming whitespace at the end, just at the beginning... should probably fix that |
| 18:32.14 | brlcad | yep |
| 18:32.45 | brlcad | if you have a vls, there is a bu_vls_trimwhitespace |
| 18:32.55 | brlcad | er, bu_vls_trimspace() |
| 18:33.10 | starseeker | wishes he had vls... |
| 18:33.22 | starseeker | nirt didn't seem to like vls much |
| 18:33.34 | starseeker | I suppose it didn't exist when it was written or some such? |
| 18:34.03 | brlcad | possible, they're both pretty old |
| 18:34.22 | brlcad | sometimes just devs that don't know about the available facilities |
| 18:34.30 | starseeker | could be |
| 18:34.48 | brlcad | it is a big package after all, you only know what you encounter unless you go looking for something specific |
| 18:35.29 | brlcad | and most resist at first because it's a simple operation to "just do it" yourself |
| 18:35.40 | brlcad | only recent that some of the facilities were even documented in HACKING |
| 18:35.50 | brlcad | just knowledge one acquires |
| 18:35.55 | CIA-21 | BRL-CAD: 03erikgreenwald * r31298 10/brlcad/trunk/src/rt/viewmlt.c: fix mlt_hit prototype |
| 18:36.28 | starseeker | yep. It hurts most in the file-reading side of things - this I can probably throw in a quick hack for now and vls-ify later |
| 18:38.05 | starseeker | checking for whitespace isn't too hard, fortunately... |
| 18:41.08 | brlcad | yeah, something like while(isspace(*cp)) cp++; while(isspace(cp[strlen(cp)-1])) cp[strlen(cp)-1] = '\0'; |
| 18:41.27 | CIA-21 | BRL-CAD: 03bob1961 * r31299 10/brlcad/trunk/src/tclscripts/archer/ArcherCore.tcl: Add code to prevent raytrace control panel being destroyed by user. Decactive panel instead of destroy. |
| 18:42.04 | starseeker | ah nice |
| 18:42.26 | starseeker | oh yeah - heh |
| 18:42.35 | starseeker | managed to hard crash his mac yesterday with archer |
| 18:42.46 | brlcad | neat |

| 19:13.15 | mafm | going home now, see you tomorrow |
| 19:22.23 | brlcad | yep, maintenance burden .. that's (part of) why there is a lot of consideration when adopting a new external dependency |
| 19:22.36 | brlcad | those are things you can't easily fix or maintain |
| 19:23.11 | brlcad | and the importance of refactoring the bigger the project gets (for BRL-CAD it's huge never-ending requirement) |
| 19:29.50 | CIA-21 | BRL-CAD: 03bob1961 * r31301 10/brlcad/trunk/src/tclscripts/archer/ArcherCore.tcl: If parentClass is not set, set it to Toplevel regardless of platform. |
| 19:39.08 | starseeker | decides to see if the archer changes avoid the hard crash... |
| 19:39.45 | brlcad | starseeker: is it user-visible? |
| 19:40.14 | starseeker | you mean the dest fix? I suppose so in the sense that if someone tries it they'll get the correct filename now... |
| 19:40.27 | brlcad | i.e. did a release go out with that bug in the last release |
| 19:40.38 | starseeker | almost certainly |
| 19:40.51 | brlcad | the it "almost certainly" .. |
| 19:41.02 | starseeker | the it? |
| 19:41.10 | starseeker | parse error ;-) |
| 19:41.23 | brlcad | then it "almost certainly" .. deserves a note |
| 19:41.28 | starseeker | gotcha |
| 19:41.50 | brlcad | would be good quick sanity check to be certain |
