A polyhedron that is constructed so as to partition space into regions in terms of distances from specific points in the space, with each region being nearer to a specific point than to any other point. The analogue of a Voronoi polyhedron in two dimensions is a Voronoi diagram. This type of diagram was discussed by the Russian mathematician Georgy Voronoi (1868–1908) in 1908. Examples of Voronoi polyhedra are Brillouin zones and Wigner–Seitz cells.
