deldir (version 0.1-12)

Delaunay Triangulation and Dirichlet (Voronoi) Tessellation

Description

Calculates the Delaunay triangulation and the Dirichlet or Voronoi tessellation (with respect to the entire plane) of a planar point set. Plots triangulations and tessellations in various ways. Clips tessellations to sub-windows. Calculates perimeters of tessellations.
