I'm working on a project that involves stenicled volumetric shadows. Origionally I was using basecode from the dev-c++ opengl example code, and I had to change the pixelformatdescriptor to allow the stencil buffer. I have swiched to sdl, but I don't know how to change the pfd so it allowes the stencil buffer. Any help would be appreciated. [edited by - reverse_gecko on March 23, 2003 12:53:10 PM]
