Re: [osg-users] Tagging triangles in the BSP

[Jean-Sébastien Guay]

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.

J-S

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.
