Detailed Description

Compute the Voronoi diagram from a Delaunay tessellation or an internal Delaunay tessellation.

Revision

1.4

This class computes the Voronoi diagram of a set of points given their Delaunay tessellation. Basically, the output points are Delaunay tetrahedra circumcenters, and the cells are convex polygons constructed by connecting circumcenters of tetrahedra sharing a face. The radius of the circumsphere associated with each circumcenter is stored in a point data array with name specifed by RadiusArrayName. The id list of poles is also provided. Poles are the farthest inner and outer Voronoi points associated with a Delaunay point. Since this class is meant to deal with Delaunay tessellations which are internal to a given surface, only the internal pole is considered for each input point.
