Qhull computes convex hulls, Delaunay triangulations, halfspace +intersections about a point, Voronoi diagrams, furthest-site Delaunay +triangulations, and furthest-site Voronoi diagrams. It runs in 2-d, 3-d, 4-d, +and higher dimensions. It implements the Quickhull algorithm for computing +the convex hull. Qhull does not support constrained Delaunay triangulations, +or mesh generation of non-convex objects, but the package does include some R +functions that allow for this. Currently the package only gives access to +Delaunay triangulation and convex hull computation.") + ;; The Qhull sources are included and are distributed under a custom + ;; non-copyleft license.
