WebVoronoi Diagram Given a point in a set of coplanar points, you can draw a boundary around it that includes all points closer to it than to any other point in the set. This boundary defines a single Voronoi polygon. The collection of all Voronoi polygons for every point in the set is called a Voronoi diagram. Tips WebThe boundary of the determined portion is the union of parabolas. There is a beachfront that exists behind the sweep line. Behind the beachfront, the Voronoi Diagram is complete and unchanging. As sweep line descends, the parabolas descend and change shape by "flattening out". Intersections of two parabolas trace the boundaries of voronoi regions. canino plaza
