Greedy triangulation algorithm
WebThe algorithm does not require the polygon to be simple, thus it can be applied to polygons with holes. Generally, this algorithm can triangulate a planar subdivision with n vertices in O(n log n) time using O(n) space. Dual graph of a triangulation. A useful graph that is often associated with a triangulation of a polygon P is the dual graph. WebIn addition to obtaining an optimal method for greedy triangulation, our result may be considered as particularly useful for the following reasons: 1. The Delaunay triangulation is very well studied and there exist many efficient implementations which compute it. This increases the hope that one might develop a greedy triangulation algorithm ...
