Hello and thanks for your answer, What you mean is that I should share the vertices when building the osg::Geometry, right?
This is possible indeed, but then OSG would still select faces in the osgUtil::PolytopeIntersector, and I would still have to convert the faces into vertices, right? So if I understand well, what you are saying is that I should then convert the faces back into vertex iindices using a reference to the primivites set triangles_osg (and not via 3 * primitives[i] + 0/1/2 as currently done). And finally I understand that this would return redundant vertex indices (which are much easier to make unique than vertex coordinates). Did I get it? Kind regards, Antoine. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=72758#72758 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
