Sample-based shaping from 3D tetrahedral mesh #1549
Description
A user has requested that we extend our sample-based shaping capability to include shaping from a 3D ProE tetrahedral mesh.
One strategy might be to use a spatial index like a BVH tree to find the candidate tetrahedra for a given point and then use barycentric coords to determine if a point is in the tetrahedron.
