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). Then the downward-facing triangles of the 3D convex hull are precisely the Delaunay triangles. The proof is left as an exercise to the reader. Webbe used for approximating more complex shapes. For example, the convex hull of a polygon in the plane or polyhedron in 3-space is the convex hull of its vertices. Also many …
