Greedy surface triangulation

Webgreedy algorithm can efficiently compute a hierarchy of provably small size and low depth. When no contractible edge exists, the triangulation is irreducible. Nakamoto and Ota showed that any irreducible triangulation of an orientable 2-manifold has at most %'&)(+*-,).0/1"243 /$56.$7 vertices. Using our proof techniques we obtain a new bound of WebIntroduction. Computing the triangulation of a polygon is a fundamental algorithm in computational geometry. In computer graphics, polygon triangulation algorithms are widely used for tessellating curved geometries, as are described by splines [Kumar and Manocha 1994].Methods of triangulation include greedy algorithms [O'Rourke 1994], convex hull …
