IRC log for #brlcad on 20100727

00:00.22 starseeker claims to have resolved some of the crap involved with building Ogre
00:01.12 starseeker also they say they've implemented their own loader for .blend files, which might mean we could use that code to make an importer for .blend format
00:19.14 ``Erik hm, a bit different than the blender game engine
00:20.10 ``Erik smells more like a C++ dealie with tighter blender support, kinda not the direction I'm looking
00:21.14 ``Erik my art bitches don't like blender and I don't like c++ :D *duck* working out the issues with cmake/ogre/mygui right now O.o
00:21.29 ``Erik also; my cats ate my earbuds for my phone. *grouse*.
00:33.44 ``Erik http://brlcad.org/~erik/20100726/
00:33.53 ``Erik if I had earbuds, I'd be calling the chinese restaurant O.o

02:39.15 starseeker ``Erik: I was thinking more about extracting what they've done to make Ogre actually build...
02:46.55 ``Erik oh, ogre builds fine
02:47.08 ``Erik the provided FindOGRE.cmake requires modification to succeed
02:47.14 ``Erik and I think I have that part down
02:47.58 ``Erik at the moment, I have MyGUI only failing on some freetype stuff
02:48.05 ``Erik and cmake sucks.
02:49.31 ``Erik and having to force it to make xcode projects because the unix makefiles never effin' work on osX is ... lame.
02:51.18 ``Erik how's the conf so far?
02:51.39 ``Erik you'll be loaning me the 2 big books and dvd set, yes?
02:52.54 starseeker sure
02:53.00 starseeker 2 big books?
02:53.07 starseeker has conference proceedings...
02:54.09 ``Erik um, used to be one huge book, mebbe ~600-800 pages, another around 150-200
02:55.18 ``Erik <-- has an attention span that makes a goldfish look like a zen master
02:55.29 ``Erik so thems're big to me :D *duck*

03:11.22 starseeker only got one large book - no raytrace conference this year
03:30.03 CIA-45 BRL-CAD: 03starseeker * r39908 10/brlcad/branches/cmake/CMakeLists.txt: Add some comments. It is NOT clear, unfortunately, whether this will result in a working setup after a make install...
03:37.15 CIA-45 BRL-CAD: 03starseeker * r39909 10/brlcad/branches/cmake/CMakeLists.txt: OK, make this a little easier to test - set up to install in a subdir of /usr/brlcad by default...

04:26.11 CIA-45 BRL-CAD: 03starseeker * r39911 10/brlcad/branches/cmake/ (CMakeLists.txt src/other/libutahrle/CMakeLists.txt): Make a quick-and-dirty CMakeLists.txt for libutahrle
04:34.16 starseeker erm.
04:34.58 starseeker brlcad: it looks like the src/other build is combining libutahrle and URToolkit into one libutahrle library - any reason URToolkit is in its own directory?
04:37.44 starseeker oh wait, did I misread that?
04:52.36 kanzure hi all.. i'm writing a STEP generator and want to test it against BRLCAD's step import utility
04:52.48 kanzure any quick hints on using that in brlcad's internals? i've never used it (yet)
04:53.06 kanzure basically i'll have one or two files for now that i'd want to load up into brlcad
04:53.21 kanzure but in the future maybe some variable number of files that i need to check for loadability (i.e. doesn't throw exceptions or errors)
04:53.49 kanzure (yes i'd be assuming brlcad's implementation is the correct one (frankly the problems are likely on my script's end))

13:09.40 CIA-45 BRL-CAD: 03erikgreenwald * r39912 10/brlcad/trunk/ (include/bu.h src/libbu/image.c): add BU_IMAGE_AUTO_NO_PIX flag to return NULL if PIX is guessed.
14:31.13 starseeker d_rossberg: ah, I hadn't noticed that - thanks!
14:34.33 starseeker kanzure: hmm. if you have a step file you can try importing via step-g, but be aware we don't have things like hierarchy preservation yet and some of the stranger NURBS representations may have issues... we're still bug swatting
14:38.23 starseeker d_rossberg: I'll be staying in the cmake branch for quite a while, so hopefully I won't be disrupting your stuff any - feel free to chime in whenever you like of course, but I'll only propose introducing the "total package" CMake build into the live trunk when I'm reasonably sure it's really robust

15:46.43 starseeker reads...

16:54.22 brlcad ``Erik: no second "big book", probably was the art and animation catalog (starseeker)
16:55.16 brlcad starseeker: libutahrle is just the rle library. urtoolkit is all of the tools (no library code) that use libutahrle
16:56.20 brlcad kanzure: totally depends on what kind of geometry you shove into your step file (we presently focus support on nurbs geometry), but there's a step-g tool that will do the import
17:07.39 CIA-45 BRL-CAD: 03brlcad * r39916 10/brlcad/trunk/misc/win32-msvc8/libpng/libpng.vcproj: remove files libpng removed
