[osg-users] Non-convex polytope picking

[Robert Osfield]

H Antoine,

You'll either need to use multiple Polytope's that decompose the concave
constraint, or implement your own post processing of the data from an
encompassing Polytope to fit.

For performance computing an ecompassing Polytope would be best.  You can
then break the volume down into parts one Plane at a time.

Robert.
