gHull: a three-dimensional convex hull algorithm for graphics hardware

We present a novel approach, termed gHull, to compute the convex hull for a 3D point set using the GPU. We exploit the fast computation of the digital Voronoi diagram and its relationship with the convex hull to compute the answer from the former rather than directly. Our algorithm is robust, while able to maximizes the parallelism available in the GPU to achieve significant speed up.
