Cause I wanna draw concave polygons or something with holes. It will be easier to have some function like tessellation in glu library. Is there any chance that I could do some tessellation by PowerVR ogles 1.0 CL sdk? Or it there any suggestion, idea or article that could make tessellation functions like it does in glu library?
If you’re looking to render dynamically generate concave polygons, it would probably be easier to use the stencil buffer method then to write a good tessellation algorithm. Chapter 14 of the OpenGL Redbook describes using the Stencil buffer to render concave polygons.
