Delaunay triangulation
Russian mathematician whose triangulation joins nearby sites so that no point falls inside another triangle’s circumcircle.
The dual of Voronoi: every site joins its neighbours into triangles. Same seed and site count as Voronoi Cells gives the matching mesh.
Boris Delaunay, 1934

The dual of Voronoi: every site joins its neighbours into triangles. Same seed and site count as Voronoi Cells produces the matching mesh: two readings of one point set.
