Computational Geometry Package
As of Version 10, all the functionality of the ComputationalGeometry package is built into the Wolfram System. »
ConvexHull — planar convex hull of a list of points
DelaunayTriangulation — planar Delaunay triangulation of a list of points
VoronoiDiagram — planar Voronoi diagram of a list of points
PlanarGraphPlot — plot the Delaunay triangulation of specified points
DiagramPlot — plot the Voronoi diagram of specified points
TriangularSurfacePlot — plot a surface according to a Delaunay triangulation
DelaunayTriangulationQ — whether a vertex adjacency list is a Delaunay triangulation
BoundedDiagram — bounded Voronoi diagram of a list of points
TileAreas — find areas of tiles established by a vertex adjacency list
