Delaunay Triangulation
The dual of the Voronoi diagram is the Delaunay triangulation. Here I've modified my earlier VD code to also output the dual (shown in red). If this can be developed further to do constrained Delaunay triangulations (arbitrary pockets with islands) then it will be useful for cutter-location surfaces in opencamlib.
The regular grid is, in the words of the GTS website, "a much more difficult test than it looks".
