Triangulations of the sphere. A: The five Platonic bodies offer a symmetric decomposition of the sphere, but only the tetrahedron, the octahedron and the icosahedron (upper row) describe an exact spherical equidistribution of vectors. B: Triangulation of the octahedron was used to arrange additional vectors on the sphere. C: Distribution of 30 search rays obtained from octahedron triangulation.
