| 05:34.16 | brlcad | starseeker: yes, it does -- the license was the primary issue and a non-starter |
| 05:36.20 | brlcad | it could conceivably be a suitable replacement for rbgui, still using custom widgets on a 3D context though |
| 05:36.39 | brlcad | and still using ogre for visualization |
| 05:40.06 | brlcad | madant1: you're welcome to help with that decoupling, the first tasks are to refactor out the tcl portions from libbu, libbn, and librt |
| 05:40.38 | brlcad | otherwise tcl isn't going away from the gui, it'll just be joined by a couple other options |

| 13:24.26 | brlcad | for editing, sure ;) |
| 13:24.35 | brlcad | they don't do ray-tracing |
| 13:24.44 | brlcad | but they probably have a tessellation routine that would be useful |

| 13:31.27 | brlcad | yep |
| 13:31.40 | brlcad | and they tessellate metaballs, that's a routine that could be reviewed |
| 13:32.07 | brlcad | they're one of the most comprehensive primitive sets close to ours |
| 13:32.11 | brlcad | a few we don't do even |
| 13:32.18 | brlcad | like the birail |
| 13:32.26 | starseeker | nifty |
| 13:32.39 | starseeker | is that openCSG doing those, or do they do their own? |
| 13:34.30 | brlcad | doing what? |
| 13:34.41 | brlcad | they have a csg-preview mode that uses opencsg |
| 13:34.47 | brlcad | http://ayam.sourceforge.net/docs/pics/csgex.gif |
| 13:35.04 | starseeker | er - doing -> "implementing core logic for" |

| 13:37.27 | starseeker | ayam BSD licensed though... cooool |
| 13:38.05 | starseeker | is still excited by QT LGPL news :-) |
| 13:39.40 | brlcad | starseeker: if you're interested in what openCSG does, there is better research on the matter |
| 13:39.55 | brlcad | some that would be close to representing an entire vehicle |

| 13:52.55 | brlcad | implementing jarek's blist's into a libcsg (along with null object detection, tree contraction, and other csg hierarchy manipulations/optimization) is something I've wanted for a long time |
| 13:53.12 | brlcad | so much that I have a src/libcsg in my checkout that has been there for years |
| 13:54.30 | brlcad | more for the csg optimizations we were talking about yesterday and having a fast isolated CSG evaluation kernel that could be optimized (e.g. for vectorization) |
| 14:00.21 | starseeker | nods |
| 14:01.21 | starseeker | how much code restructuring/refactoring do you think that would involve? |
| 14:01.50 | starseeker | could see something like that being as bad/worse than libged... |
