Re: [osg-users] Tagging triangles in the BSP
Hello Andrew, I hear that the OSG now supports BSP tree capability. Perhaps what you heard was that OSG now supported intersection testing with a *kd-tree* structure? That would be true, but not BSP trees (yet). I was wondering if this included functionality for tagging metadata onto the individual triangles in the BSP tree, or even onto the individual triangles in a Geode. If so, what is the method? If not, where would be a good place for us to attach such functionality? Robert will be better placed to answer this, he implemented the functionality whereas I just dabbled with it (and other kd-tree implementations). Sorry I can't help more.

Re: [osg-users] Tagging triangles in the BSP
Hi Chen, The OSG core seems not to support BSP tree at the moment. I have just created an open source project named "osgModeling" ( http://code.google.com/p/osgmodeling/), to support NURBS and kinds of modeling methods, and the BSP tree of individual geometries (to help do boolean operations). It's still immature and has a long way to go. Advices and criticism are always appreciated. I'm working on the subdivision of polygons at present. If you have any requirements or sharable codes, I'm very glad to discuss about it.
