http://karthik.ise.illinois.edu/courses/ie511/lectures-sp-21/lecture-7.pdf 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.
