Hello Robert, I totally get your point when you say I stretch osg::Polytope a bit too far, this is also the feeling that I had...
As for using a custom hierarchy of osg::Plane, I understand that you are talking about a layered approach for intersections. Having the scene first intersect with a rough polygon (e.g. the bounding box of the initial polygon) and then refining the polygon. Even a 2 steps approach should drastically speed-up the intersections test. That's a really good idea, thanks!
