00:01.06 yukonbob no dynamic geom in brl-cad either, correct? so if one is modelling a vehicle w/ say wheels that need to travel up/down on suspension, the designer would need to do some of their own work to determine that the wheels don't collide w/ the wheel wells?
00:01.23 brlcad actually we do have rudimentary dynamic geometry
00:01.27 yukonbob !
00:01.33 yukonbob documented?
00:01.36 brlcad hence all the videos, which you've probably never seen ;)
00:01.50 yukonbob has seens ronja videos...
00:02.00 yukonbob are you talking classified videos?
00:02.05 brlcad we actually have like a hundred videos
00:02.10 brlcad nope
00:02.15 brlcad most of them are public release materials
00:02.23 yukonbob awesome!!!
00:02.25 yukonbob ?link
00:02.40 brlcad just not in digital format .. sitting on shelves and in boxes
00:02.45 yukonbob hahahahaha
00:02.56 yukonbob ok -- so I need to order a VHS copy to see these :)
00:03.04 brlcad for some of them
00:03.05 yukonbob like netflix ;)
00:03.21 brlcad some are betacam, some umatic, some old magnetic spools
00:03.56 brlcad hopefully can get some of them digitized soon
00:07.27 brlcad it's all mostly done via "joints", which is a manual rigging system
00:07.42 brlcad the anim tools help perform the per-frame articulattions
00:07.57 brlcad as well as other rt features like multirender command scripts
00:08.33 brlcad that could easily make for a great gsoc project, but then support for constraints and parametric equations really helps that effort
00:09.49 brlcad http://brlcad.org/OLD/reports/tr-313/chapt0.html touches on some of the basic concepts
00:09.57 yukonbob nice
00:10.14 brlcad though that particular report doesn't cover joints, just basic transformations
00:10.33 yukonbob it's a start...
00:11.50 brlcad caveat warning .. last time *I* tried reproducing the results of that paper, I ran into a problem with our quaternions (i.e. our view representation) .. yet someone on the mailing list had no problems
00:12.26 yukonbob ie: diff't axis representation?
00:12.44 brlcad hm?
00:12.56 brlcad how the view matrix is specified
00:13.18 brlcad (quaternions are more compact than your traditional homogenous matrix)
00:13.19 yukonbob for selecting rhs/lhs of object?
00:13.32 yukonbob isn't clear on this terminology :P
00:13.43 brlcad don't worry about it :)
00:13.51 brlcad quaternions give everyone a headache :)
00:14.04 brlcad cept math nuts
00:14.10 yukonbob heh -- /me wasn't worried -- is always keen to learn new stuff, though :)
00:14.15 brlcad and even then, it's like a mild migraine
00:14.43 brlcad have fun: http://en.wikipedia.org/wiki/Quaternion :)
00:15.03 brlcad and: http://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation
00:15.04 yukonbob loads it, puts aside in diff't screen for later reading :)
00:15.21 brlcad goes home
00:15.33 yukonbob chat later

07:42.45 CIA-34 BRL-CAD: (using local units), and support for additional output formats (tables). this
07:42.47 CIA-34 BRL-CAD: feature was requested by _many_ (most?) modelers and analysts.
