Detailed Description

A topological coordinate of dimension N are the N+1 ids of neighboring N+1 Voronoi generator points whose spokes form half spaces intersecting at a tile (2D) / hull (3D) vertex.

In non-degenerate situations, the topological coordinate enumerates a Delaunay simplex (triangle 2D or tetrahedron 3D). The topological coordinate is used to topological merge coincident points, generate a Delaunay triangulation, characterize local topology (e.g., for smoothing), and verify the correctness of the resulting Voronoi tessellation or its dual Delaunay triangulation.
