Changed the algorithm to avoid filtering colinear/duplicate vertices unless it can't triangulate the polygon otherwise. Improves performance on simpler shapes and fixes some 3D use cases. Weblation of a simple polygon of nvertices always has n−2 triangles. Various algorithms have been developed for triangulation, each characterized by its asymptotic order as ngrows …

The Tessellation App. I managed to put together the above demonstration app using WebGL that shows the two tessellation algorithms in operation and allows you to visually compare the results.

ExtrudePolygon adds a depth option to CreatePolygon. The extrusion is carried out down the vertical y axis from the polygon shape in the horizontal xz plane. Like CreatePolygon it requires an Earcut script. Since it can be concave it requires a procedure to fill the polygon with triangles and an Earcut method is used. chinese in charleston
