It does apply to a large number of concave shapes. The convex assumption is too conservative. --Seb I applies to all polyhedra that, when you "blow them up" and "smooth them out", look like a sphere. So the polyhedron can have "dents", because they will go away when "blowing up", but it cannot have holes like a torus for example. Also, like a sphere, the polyhedron has to be connected. --AxelBoldt |
