Algorithm to compute the Voronoi diagram of points, line segments and triangles in $\mathbb{...

Voronoi diagrams of points in $R^3$ are now implemented in several software libraries and can be computed, for example, in a few lines of Python code. This has not always been the case, so it still is …

Algorithm for grouping tetrahedra from Voronoi diagram

Chapter 27 of The Handbook of Discrete and Computational Geometry enumerates the complexity of known Delaunay triangulation algorithms of any dimension (see Table 27.2.1 there). For 3D Delaunay the wo …
