WebFeb 27, 2024 · Virtually all published triangulation algorithms assume that the polygon is simple, i.e., that the vertices of the polygon are the only points of the plane that belong to two edges, and that no point of the plane belongs to more than two edges. Obviously, the requirement to be simple prevents a polygon from having self-intersections. WebPolygon triangulation is, as its name indicates, is the processes of breaking up a polygon into triangles. Formally, A triangulation is a decomposition of a polygon into triangles by a maximal set of non-intersecting diagonals. …
