# Tesselation of Mono Connected Non Convex Polygon

, 6 Feb 2002 CPOL
 Rate this:
Tesselation of mono connected non convex polygon

## 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.

 Change the line:`for( register int i=0 , j=1 ; j < nPoints ; i++ , j++ ){`to:`for( register int i=0 , j=1 ; i < nPoints ; i++ , j++, j=j%nPoints ){`and normal of the polygon will be calculated correctly.Torsten
