Greedy surface triangulation

WebOne use of the greedy triangulation is as an approx-imation to the minimum weight triangulation (MWT). Given a set S of n points in the plane, a Minimum ... surface. Wang and Aggarwal use a minimum-weight triangulation in their algorithm to reconstruct surfaces from contours [32]. Though it has been shown how to 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 …
