algorithm

In this routine, we will utilize the fact that R3d can intersect a non-convex polyhedron with planar faces with a convex polyhedron (more precisely, R3D can clip a non-convex polyhedron with a set of planes). We are given a target polyhedron with possibly non-planar faces to be intersected with a list of source polyhedra again with possibly non-planar faces. We will convert the target polyhedron into a set of convex polyhedra using a symmetric tetrahedral decomposition (24 tets for a hex). We will convert each source polyhedron into a faceted non-convex polyhedron where each facet is a triangle and therefore planar.

If this class is being adapted for use with a different intersector and it can only intersect convex polyhedra, both target and source polyhedra may have to be decomposed into tets
