[osg-users] Computing BoundingBox from RenderBin ?

[Wojciech Lewandowski]

Amount of job you do - causes me to suspect that you are twins at least. 
After cloninig there would be a three or four of you ?

I also noticed CustomPolytope class and its methods. Does it work for some 
special cases only or can be used to compute intersections of any arbitrary 
convex volumes ? It looks like it can directly used in Trapezoidal Shadow 
Map computations.

Cheers,
Wojtek
