Voronoi pole : ウィキペディア英語版 | Voronoi pole In geometry, the positive and negative Voronoi poles of a cell in a Voronoi diagram are certain vertices of the diagram. ==Definition== Let be the Voronoi cell of the site . If is bounded then its ''positive pole'' is the Voronoi vertex in with maximal distance to the sample point . Furthermore, let be the vector from to the positive pole. If the cell is unbounded, then a positive pole is not defined, and is defined to be a vector in the average direction of all unbounded Voronoi edges of the cell. The ''negative pole'' is the Voronoi vertex in with the largest distance to such that the vector and the vector from to make an angle larger than .
