How do I tesselate polygons with optimizer/performer. I tried to use the opTessAction class but was unsuccessful. My problem is that I am unable to render concave polygons corectly with both optimizer and performer and hence I wanted to tesselate the polygon. In performer I tried to use the pfdTriangulatePoly in the pfdUtil library which is supplied as unsupported code. The program crashes. Can anybody please advice me on how I can tesselate polygons (concave specifically) with optimizer/performer.
