Tesselation of mono connected non convex polygon

Sample Image - PolyTry.jpg

Introduction

A simple alternative to OpenGL polygon tesselation callback. You can focus on file triangle.h that contain the class to evaluate convexity of polygon and tesselate the polygon. No extra points are inserted. You can work only with planar polygon also in 3D.

Every suggestion in order to speed up the class and create better tesselation ('better' triangles) is appreciated.

(excuse me for my poor english too Blush | :O ) )
 
I didn't want you to use a delaunay algorithm. My message intention was to show another way than Delaunay to improve you algorithm. The one i describe is only an idea to turn edges to have better result. And i don't take it from any book too and i don't think it's computationnal intensive. I think this idea can be plug as a post process of you algorithm.
I respect you intention to contribute. And my idea is to contribute to the improvment of your. This was my only intention.
Thanks
