Delaunay simplexes

An example of Delaunay triangulation in two-dimensions

A Delaunay simplex is the dual of the Voronoi diagram. Delaunay simplexes were developed by Борис Николаевич Делоне. In two-dimensions $({\mathbb {R} }^{2})$ it is more commonly known as Delaunay triangulation, and in three-dimensions $({\mathbb {R} }^{3})$, as Delaunay tetrahedralisation. Delaunay triangulation fulfils the so called empty circle property, i.e. the circumscribing circle of each facet of such a triangulation does not contain any other vertex of the triangulation in its interior. A similar property holds for tetrahedralisation in three dimensions.
