| 23:02.21 | brlcad | interesting list of apps here: http://www.p-gis.com/2010/02/opensource-gis-softwares.html |
| 23:11.17 | starseeker | wow, that's a very comprehensive list |
| 23:13.58 | brlcad | ah, now this is related to the topology validation route I was hoping we'd go: http://trac.osgeo.org/geos/ |
| 23:14.14 | brlcad | "just" needs to be expanded to 3D |
| 23:15.16 | starseeker | hmm: http://www.thp.uni-duisburg.de/Ygl/ReadMe.html |
| 23:17.13 | starseeker | 'course, I suppose Mesa would do a similar job... |
| 23:17.25 | starseeker | brlcad: "topology validation"? |
| 23:19.08 | brlcad | starseeker: basically the building block components we talked about a long while back |
| 23:19.13 | brlcad | line-line intersect |
| 23:19.14 | starseeker | ah |
| 23:19.17 | brlcad | line-curve intersect |
| 23:19.28 | starseeker | what SISL implements |
| 23:19.31 | brlcad | that geos package basically does exaclty that |
| 23:19.38 | starseeker | hmm, cool :-) |
| 23:19.59 | brlcad | just they work with 2d entities, as they're mirroring a java api |
| 23:20.17 | brlcad | one that was pretty well thought out though |
| 23:20.25 | starseeker | cool |
| 23:20.30 | brlcad | would probably extend very nicely to our domain |
| 23:21.35 | brlcad | so you could take a given geometry and 1) say whether it's "valid" or not (solid, closed, manifold, non-intersecting, etc) and 2) assist with boolean operations on surface surface intersections |
| 23:22.56 | starseeker | nods |
| 23:24.51 | starseeker | twitches seeing a big list of free software to try out and having no box to do it on... argh |
| 23:26.26 | brlcad | big advantage of geos over sisl, it's license fits ;) |
| 23:26.35 | starseeker | yep :-) |
| 23:26.49 | starseeker | I've accepted that we can't use SISL, it just sucks :-P |
| 23:27.39 | brlcad | another thought regarding tess support, I bet we could pull the code directly from mesa for GLU |
| 23:28.06 | brlcad | that should be the old SGI code, probably not even modified |
| 23:28.21 | starseeker | you mean for NURBS? |
| 23:28.26 | brlcad | SGI's opengl stuff was all open sourced several years ago |
| 23:28.26 | brlcad | yeah |
| 23:28.27 | starseeker | hadn't thought of that |
| 23:28.38 | brlcad | MIT-style license, so it's good |
| 23:28.48 | starseeker | yeah - I think that was their "reference" implementation or some such? |
| 23:28.55 | brlcad | bets if you download mesa, it's there |
| 23:29.48 | starseeker | if not, maybe here: http://oss.sgi.com/projects/ogl-sample/ |
| 23:31.31 | starseeker | hmm - Bogdan Sikorski is called out specifically for writing the GLU NURBS and polygon tessellator in Mesa, so it's there |
| 23:34.36 | starseeker | brlcad: I never could find trimmed -> untrimmed papers online - any helpful pointers? |
| 23:34.42 | brlcad | another one to keep an eye on (or get involved with) .. http://thread.gmane.org/gmane.comp.lib.boost.devel/197108 |
| 23:34.48 | brlcad | boost.geometry |
| 23:37.51 | starseeker | ah, this looks promising: http://cgit.freedesktop.org/mesa/mesa/tree/src/glu/sgi/libnurbs/nurbtess |
| 23:38.30 | brlcad | yep, that'd be it |
| 23:38.50 | brlcad | all of http://cgit.freedesktop.org/mesa/mesa/tree/src/glu/sgi/libnurbs |
| 23:39.05 | starseeker | is curious about libtess |
| 23:39.17 | brlcad | even libtess too, but that's a tessellator callback interface for opengl |
| 23:39.24 | starseeker | ah |
| 23:41.45 | starseeker | heh - sorry ``Erik, looks like more C++ |
