Detailed Description

Pseudocode

1. Find "back" boundary triangle (O(n))
2. Find enclosing tetrahedron
3. While tetrahedron exists 3.1 Find intersection with other faces on tetrahedron 3.2 Find new tetrahedron

Raytracing in ISMesh datastructure. Assumes that the boundary surface of the ISMesh is convex Assumes that the set of boundary faces are static (if not call rebuild_boundary_cache() after changes).
