Voronoi Diagrams Next: Nearest Neighbor Search Up: Computational Geometry Previous: Triangulation Voronoi Diagrams Input description: A set S of points . Problem description: Decompose space into regions around each point such that all the points in the region around are closer to than they are to any other point in S. Discussion: Voronoi diagrams represent the region of influence around each of a given set of sites. If these sites represent the locations of McDonald's restaurants, the Voronoi diagram partitions space into cells around each restaurant. For each person living in a particular cell, the defining McDonald's represents the closest place to get a Big Mac. Voronoi diagrams have a surprising variety of uses: ● Nearest neighbor search - For a query point q, finding its nearest neighbor from a fixed set of points S is simply a matter of determining which cell in the Voronoi diagram of S contains q. See Section for more details. ● Facility location - Suppose McDonald's wanted to open another restaurant. To minimize interference with existing McDonald's, it should be located as far away from the closest restaurant as possible. This location is always at a vertex of the Voronoi diagram, and it can be found in a file:///E|/BOOK/BOOK4/NODE187.HTM (1 of 4) [19/1/2003 1:31:41]
