08:30.28 tflendrich hello everyone :) Let me introduce myself: I'm Tomasz, a student interested in taking part in GSOC with BRL-CAD
08:31.54 tflendrich a year ago, you had lots of interesting project ideas and it hasn't changed a bit, so it's hard to choose something (not that I complain that there's much to do)

08:57.27 ickby tflendrich: make sure to also have a look at the other organisations which applied together with brl-cad, for example linuxcnc, stepcode, librecad and freecad
08:57.37 ickby for freecad the ideas are here:http://www.freecadweb.org/wiki/index.php?title=Google_Summer_of_Code
08:57.49 ickby disclaimer: I'm from the freecad dev team, :)
09:04.13 tflendrich ickby: haha, thanks!
09:05.18 ickby your welcome :) it just seems that most studends do not realized that the BRL-CAD GSoC organisation is a combined proposal of multiple orgs, so I'm mentioning that from time to time

17:28.45 Notify 03BRL-CAD:starseeker * 67394 (brlcad/trunk/doc/docbook/system/mann/rm.xml brlcad/trunk/src/libged/CMakeLists.txt): Revert work on rm command - won't be ready for prime-time by release, so go with old behavior.
17:30.02 brlcad tflendrich: welcome
17:30.28 brlcad tflendrich: note that our ideas list is a little out of date -- we do have some priority topics this year, which you can see on the brlcad-devel mailing list archives
17:30.41 brlcad might help you narrow down on a topic
17:31.04 brlcad and definitely check out our partner orgs!
17:31.25 Notify 03BRL-CAD:starseeker * 67395 brlcad/trunk/TODO: Put rm work in the backlog
17:32.51 brlcad tflendrich: to answer your private question, we don't know how many slots will be assigned, but we do want each partner org to have a student or two working
17:33.54 starseeker brlcad: did you want a preliminary look at my thoughts on analyze command options, or should I go ahead and toss them into the libged TODO entry?
17:34.45 brlcad tflendrich: some more, some less
17:34.56 brlcad starseeker: sure, either way
17:35.30 starseeker k, just didn't want a student to start in on it before we're done hashing it out - I doubt very much this is final form...
17:43.42 brlcad I got no analyze religion other than KISS
17:44.01 tflendrich brlcad: okay, thanks
17:45.21 starseeker heh. this is probably doomed then, but I'll toss it up anyway.
17:45.52 Notify 03BRL-CAD:starseeker * 67396 brlcad/trunk/src/libged/TODO: Add some very preliminary thought on what a general/unified analyze command might look like...
17:50.49 starseeker brlcad: do you happen to remember what specifically to look for with Windows wireframes (TODO entry?) I've drawn a few simple things like moss.g in MGED windows in recent BRL-CAD Windows builds successfully...
17:51.03 brlcad what does --visualize do?
17:51.25 starseeker draw the wireframe of the bounding box, the dot for the centroid, the mesh for the convex hull, etc.
17:51.35 starseeker without creating actual geometry objects
17:52.32 brlcad starseeker: TODO was just a quick sanity check to make sure they weren't horribly brokwn by a change
17:52.41 brlcad so if you saw a wireframe, not horked :)
17:52.46 starseeker cool :-)
17:53.11 starseeker will re-confirm once the latest build completes (need binary with reverted rm command) then I'll nuke that one
17:56.40 brlcad starseeker: command design looks pretty good to me, looks like you covered most things
17:57.35 starseeker is tempted to support =obj.s syntax for components too (easy way to extract a set of faces from a B-Rep, say) but that would probably expand the scope of the command too far
17:57.37 brlcad not sure we have consistent terminology .. a surface and a face are synonymous or ambiguous
17:57.48 starseeker different in B-Rep, same in mesh
17:58.39 brlcad right
17:59.06 starseeker and other primitives will have primitive specific piece parts (like the voxel example)
17:59.12 starseeker open to ideas on that
17:59.23 brlcad would be good to generalize to all entities if we can
17:59.27 starseeker nods
18:00.35 brlcad to simplify the interface and code, might make sense to only support one analysis at a time
18:01.04 brlcad since the other options will very likely vary per property (e.g., tolerance and visualize)
18:01.26 brlcad an option to create the geometry would be good, might be mergable with visualize
18:01.32 starseeker hmm - good point. visualize I can see working mulitple property, but tolerance is a stopper
18:01.54 starseeker that may preclude folding gqa under this then
18:02.26 starseeker users won't want to re-run raytracing to get (say) volume and moment of inertia if the raytracing is expensive
18:02.38 brlcad you might want to visualize one prop, like bbox, and might be surprised at all the stuff created by other properties (e.g., overlap)
18:02.48 starseeker true
18:03.05 brlcad yes, agreed, but we can handle that by giving analyze a context it can reuse
18:03.15 starseeker ah - some sort of cache?
18:03.41 brlcad hey good idea.. wasn't specifically thinking that, but even better
18:04.06 brlcad was thinking a command-specific hook in the ged struct where it could hang a container
18:04.11 starseeker create an "analysis object" that can then be interrogated for various properties...
18:04.13 brlcad but having a global cache is even better
18:04.21 brlcad (accessed via the ged struct)
18:04.51 brlcad brb
18:04.57 starseeker nods
18:08.06 starseeker confirmed - wireframes came up in mged
18:09.03 Notify 03BRL-CAD:starseeker * 67397 brlcad/trunk/TODO: Wireframes do draw on Windows with MGED.

19:25.24 Notify 03BRL-CAD:starseeker * 67398 brlcad/trunk/src/tclscripts/rtwizard/main.c: Start working on the setup to make the command line bu_opt inputs feed the rtwizard tcl script. Need to do this for the GUI even if we can eventually replace the command line mode.
19:31.05 brlcad wonders why 67398 indented the int function return types

22:06.42 starseeker brlcad: sorry about that - my vim setup does that automatically for some reason
22:07.06 starseeker usually I fix them manually - forgot to there because that's an intermediate checkpoint
