Could you perhaps describe in more detail what exactly you want to know?

YEs:
i need to draw some concave area with TRIANGLE_FAN…infact there is a problem while drawing this kind of area because there are triangles that not supposed to be there!.. it’s clear?

thanx,
Eym

While you can draw all convex polygons as TRIANGLE_FAN, that only works with some concave polygons. You need to triangulate the polygon: http://en.wikipedia.org/wiki/Polygon_triangulation .
