Voronoi tessellations of regular lattices of points in two or three dimensions give rise to many familiar tessellations.. A 2D lattice gives an irregular honeycomb tessellation, with equal hexagons with point symmetry; in the case of a regular triangular lattice it is regular; in the case of a rectangular lattice the hexagons reduce to ...
