oposite of glScissor

Hi, how can I render a square with out a smaller square inside it. I basically mean, that the square is supposed to look like a picture frame afterwards.
thx

you could use the stencil test

i think the tessalation objects of glu provide a way to render complex polygons
so you should take a look at the glutess… functions (i think glutesscontour is the right thing here)
