03:32.34 boj I still can not make 'gqa' work correctly on BoT(just a single plane with thickness 2), the debug information indicates that it can find a proper grid spacing automatically and get 2 samples per model pixel, but the program still does not response and can not output the result. :(
03:33.14 boj but for sphere, it alwasys gives result very quickly not matter it is in BoT or b-rep
03:41.13 boj here is the information it gives, and it *seems* stopping at this stage. http://paste.ubuntu.com/18857064/
03:42.17 boj I wonder if a plate does not have thickness in one axis, so this tool does not work for this case?
03:43.49 boj I am thinking should I design a convex/concave arc surface, it might work?

04:28.57 Notify 03BRL-CAD:brlcad * 68238 brlcad/trunk/NEWS: support for joints was implemented during the 2014 summer offsite and aftwarwards by several hands. still in a preliminary dev state, but worth mentioning as it was substantial effort and is usable for limited editing purposes. more important to let community know this is an area of work
04:34.27 Notify 03BRL-CAD:brlcad * 68239 brlcad/trunk/src/libgcv/plugins/fastgen4/fastgen4_write.cpp: need to refactor as it is a common problem category unaddressed.
04:38.48 Notify 03BRL-CAD:brlcad * 68240 brlcad/trunk/NEWS: nick improved the help string but also make saveview not dump out scripts pointing to a non-existent temp working database. now sometime valid, valid by default, instead of always inavlid (when run from archer).
04:43.44 Notify 03BRL-CAD:brlcad * 68241 brlcad/trunk/NEWS: keith improved the performance of wireframes in both mged and archer, particularly when using display lists, where it was building the lists 5 times. now it only builds the lists as needed. main commit is 64326.
04:50.35 Notify 03BRL-CAD:brlcad * 68242 (brlcad/trunk/TODO brlcad/trunk/src/util/bwcrop.c): carl's commit in r65699 looked clearly wrong in the fseek, but unclear on quick review whether the yindex adjustment is correct or not. schedule bwcrop for testing, but deeming not release-critical.
04:52.24 Notify 03BRL-CAD:brlcad * 68243 brlcad/trunk/TODO: check pixembed too per r64202

18:29.33 Stragus Eh starseeker brlcad, I would be curious if you make that comparison
18:30.59 Stragus Although I believe in the mesh decimation code (assuming that's mine), I aimed for high quality... and performance
19:24.52 brlcad Stragus: *nod*
19:25.26 brlcad we did find a few test cases that made it crash when we tried to set up some examples for a presentation
19:26.03 brlcad but didn't investigate, and that point sample was no implication on how robust it is
19:36.28 Stragus It expects and requires properly prepared meshes, no edge must be shared by two triangles except once in the reversed order (AB, BA)
19:36.57 Stragus I probably should have added some preliminarly error checking/correction, but it was always fed good data when I wrote it
