02:56.25 CIA-65 BRL-CAD: 03brlcad * r50562 10/brlcad/trunk/NEWS: nick fixed a bug in the make_pnts command where the input datafile wasn't being released. this is particularly problematic on windows and other platforms that do not relinquish the file. r49409.
03:23.20 crdueck hey all, i've made a patch refactoring libbu/lex.c: https://sourceforge.net/tracker/?func=detail&aid=3527142&group_id=105292&atid=640804 i'd appreciate someone taking a quick look at it, thanks
03:25.47 crdueck refactoring a small section, not the whole thing, heh
04:17.05 starseeker digs into the texlive build process out of curiosity and is agast
04:17.51 starseeker suddenly the DocBook toolchain doesn't look so bad
04:24.09 CIA-65 BRL-CAD: 03brlcad * r50563 10/brlcad/trunk/NEWS: nick fixed a bug in the anim_keyread and anim_orient animation tools in r49407 fixing a coverity-detected swapped argument bug. looks like the bug should be evident if one tried to set an xyz view angle.
04:35.15 CIA-65 BRL-CAD: 03brlcad * r50564 10/brlcad/trunk/NEWS: the same swapped arguments bug seen in some of the animation tools is also true in libged/mged commands such as this one, ypr. detected by coverity, fixed by nick.

11:51.55 CIA-65 BRL-CAD: 03erikgreenwald * r50566 10/brlcad/trunk/src/libbu/ (CMakeLists.txt Makefile.am booleanize.c test_booleanize.c):
11:51.55 CIA-65 BRL-CAD: Apply patch for tracker ID 3519874. Adds a test program for booleanize as well as fixing a bug in the implementation of booleanize.
11:51.55 CIA-65 BRL-CAD: https://sourceforge.net/tracker/index.php?func=detail&aid=3519874&group_id=105292&atid=640804
11:55.23 CIA-65 BRL-CAD: 03bob1961 * r50567 10/brlcad/trunk/src/tclscripts/lib/ (Ged.tcl RtImage.tcl): Added a perspective parameter to cadwidgets::Ged::make_image, cadwidgets::Ged::make_image_local and cadwidgets::rtimage. Also added an extra rtedge call for color objects that are edged in cadwidgets::rtimage.

12:07.13 d_rossberg kane_: how is your progress with the patch?
12:08.07 kane_ d_rossberg: i am working on it, but it is realy hard, i have to understand how the whole DM works.
12:10.23 d_rossberg what are you working on?
12:11.25 kane_ if you attach a ogl window in tk and close it mged will close,too
12:14.47 kane_ i have tried to debug it with gdb, but i got only a Errorcode 0 without anything else.
12:18.11 d_rossberg try to set a brakpoint at exit() in gdb
12:51.26 kane_ when I set a breakpoint on mged_finish, i get this: [Thread 0xa824bb40 (LWP 6776) exited]
12:51.28 kane_ [Inferior 1 (process 6773) exited with code 01]
12:51.30 kane_ warning: Error removing breakpoint 0
12:58.51 d_rossberg did you tried "break exit" in gdb?
12:59.18 d_rossberg this should catch bu_bomb() etc. too
13:08.46 CIA-65 BRL-CAD: 03bob1961 * r50568 10/brlcad/trunk/src/tclscripts/lib/Ged.tcl: Minor mod to cadwidgets::get::make_image_local (i.e. need to call perspective with a view).
13:12.36 kane_ I get the same, I think there is no error. Maybe mged believe that the first attached window is the main window. Accordingly on close he will exit mged, too.
13:17.33 brlcad kane_: try break _exit
13:17.37 d_rossberg that's right, but if you have a brakpoint at exit() and the debugger stops there you can examine the call stack (backtrace) at this point
13:18.31 brlcad even if there's no error, there's only a couple ways to leave an application
13:18.59 brlcad could put a breakpoint on main()'s return too if it's exiting from event processing
13:20.13 CIA-65 BRL-CAD: 03Cprecup 07http://brlcad.org * r3669 10/wiki/User:Cprecup/GSoC2012_progress: patch for test_booleanize.c applied in the revision r50566

14:09.17 starseeker brlcad: if you've got a second, I could use an opinion on patch 3526551 (the eto_brep.cpp patch) - I think we're down to issues that are solver related rather than csg->NURBS conversion related, based on what I'm seeing
14:09.45 ``Erik huzzah for fuzzy numbers O.o
14:23.35 *** part/#brlcad kane_ (~kane@e181169118.adsl.alicedsl.de)
14:27.40 starseeker yeah, pixdiff only reports 27 off by many - nowhere near enough to explain those patterns

16:09.10 CIA-65 BRL-CAD: 03bob1961 * r50569 10/brlcad/trunk/src/tclscripts/lib/RtImage.tcl: Missed a perspective usage. Call fb-pix at the end of the color object section.
16:45.01 CIA-65 BRL-CAD: 03bob1961 * r50570 10/brlcad/trunk/src/ (libged/perspective.c libtclcad/tclcad_obj.c): Don't need to compute the perspective matrix in tclcad_obj.c/go_draw() (i.e. use the previously computed gv_pmodel2view). Mod ged_perspective() to calculate gv_pmat if gv_perspective is greater than 0.

18:09.05 CIA-65 BRL-CAD: 03starseeker * r50572 10/brlcad/trunk/src/tclscripts/rtwizard/rtwizard.tcl: Add a perspective slot to the rtimage call - zero for now, but need to add the perspective option to rtwizard command line.

22:39.28 ``Erik what're the grey oval and sliver? exact match?
22:39.44 starseeker I think...
22:39.57 starseeker only 27 pixels were off by many
22:40.28 ``Erik any clue which 27?
22:40.39 starseeker unfortunately, no
22:40.56 starseeker was discussing that with brlcad earlier - he said there were some pix tools that could help with that
22:41.32 ``Erik be trivial to write a filter to show it, what about nirt differences to compare distance vs normal vs point->light ray?
22:42.36 ``Erik (when tie looked like that, I said "good 'nuff", still need to redo comparisons with that 1mm fix indianlarry found to see if it still has the same look...) :D

22:43.56 starseeker I'm more disturbed by the odd behavior in the subtraction case
22:44.56 ``Erik *nod* I'd still think it's a side effect issue from uninitialized or overwritten memory from what you told me
22:45.17 starseeker prepares a better screen shot of that effect
22:46.03 ``Erik pokes at glsl some more O.o
22:47.48 starseeker http://bzflag.bz/~starseeker/eto_implicit-eto_brep.png
22:48.07 starseeker kinda nifty if it weren't so annoying
22:49.20 ``Erik art!
22:51.43 starseeker beware, glsl might poke back
