The Voronoi tessellation is the dual graph of Delaunay triangulation. Voronoi diagram is often used to create neighborhood analysis map of a set of points.

This function is exposed here as a derivative bonus from the Delaunay triangulation implementation. It's certainly not very useful in the context of a 3D GIS application but it create cool patterns that maybe some people will find interesting for their project !

Usage : select a point cloud mesh and run the operator
