A direct algorithm for computing the Delaunay triangulation in three dimensions is presented. The algorithm uses a 3D cell data structure to preprocess the data, a range searching procedure to find Delaunay points quickly, and a shelling mechanism to put tetrahedra together in such a way that completeness and correctness are guaranteed. A face and an edge lists are used to govern the triangulation process. The convex hull can also be computed at no extra cost.
