I can draw quadrics ok, but for somereason when I glEnable(GL_DEPTH_TEST) they disappear. I have set space for the z buffer, so thats not the prob, and it is the only object in the scene, so nothing can be blocking it. Any ideas? -Fuzz

Could you be more precise ? What kind of quadrics ?
Have you tried to download the samples ? Do they work ?
