An efficient simple polygon triangulation algorithm based on a uniform plane subdivision
Lamot, Marko ; Žalik, Borut
A new algorithm for triangulating simple polygons is proposed. The algorithm uses a uniform space subdivision to speed-up the triangulation. The algorithm efficiently combines two approaches: an ...ear-cutting and a diagonal insertion. Comparison with the popular polygon triangulation algorithms (Sloan's ear-cutting algorithm, Seidel's randomized incremental algorithm, algorithm based on Graham scan, and Garey's et al plane-sweep algorithm) for different classes of simple polygons (general, convex, monotone, star-shaped, and the polygons taken from a GIS database) is presented. For general polygons and GIS polygons, the proposed algorithm is the most efficient among the tested algorithms.
