Resum
We present a novel Cell-To-Cell Visibility (C2CV) algorithm, which given two polyhedra,A and B and a connected and oriented manifold triangle mesh, S offers a simple, fast, and conservative test for detecting when A and B are occluded from each other by S. Previously disclosed C2CV algorithms either relied on costly occlusion fusion or were restricted to convex or “apparently convex” occluders, which makes them inappropriate for scenes where potential occluders are arbitrary triangulated sur...
