In geometry, a polyhedron (plural polyhedra or polyhedrons; from Greek πολύ (poly-) 'many', and εδρον (-hedron) 'base, seat') is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices. A convex polyhedron is the convex hull of finitely many points, not all on the same plane. Cubes and pyramids are examples of convex polyhedra.

WebA nice consequence of implementing 3D convex hull is that we get Delaunay triangulation for free. We can simply map each point ( x, y) into a 3D point ( x, y, x 2 + y 2).
