Ok, so I was surfing the net and came across the extension GL_PHONG_WIN used like glShadeModel(GL_PHONG_WIN). I had three shadings, flat, smooth, and phong. I saw absolutely no differance between the smooth and phong shading when I included lights and everything and was wondering if anybody else has ever used phong shading like this. Do you notice a differance? I''ve implemented it on the teapot, and sphere with the sphere having different tesselations. I also implemented in on a cube. Just curious. Thanks. Mat

Actually, this extension was never implemented.

btw, before you can use any OpenGL extension, you must to check if it''s available at all...

OpenGL Developer FAQ : How can I find which extensions are supported?
