WebMar 26, 2024 · Updated Answer. The best solution I could come up with is to first create voronoi regions using the boundary points (a small inside buffer was needed to ensure all boundary points are considered for the voronoi) as point input (also add interior points for polygons with holes). In computational geometry, polygon triangulation is the partition of a polygonal area (simple polygon) P into a set of triangles, i.e., finding a set of triangles with pairwise non-intersecting interiors whose union is P. Triangulations may be viewed as special cases of planar straight-line graphs. When there are no holes or … See more Over time, a number of algorithms have been proposed to triangulate a polygon. Special cases It is trivial to triangulate any convex polygon in linear time into a fan triangulation, by adding … See more • Both triangulation problems are a special case of triangulation (geometry) and a special case of polygon partition. • Minimum-weight triangulation See more • Demo as Flash swf, A Sweep Line algorithm. • Song Ho's explanation of the OpenGL GLU tesselator See more • Nonzero-rule • Catalan number • Planar graph • Flip graph See more
