Hi, I''m a new to OpenGL, I have tried a little under Delphi/SDL and plan to keep it that way, but now I''m looking for a good book on the subject. The red book can be found online (at least the older version) and now I think I should either get the Superbible or the OpenGL Game Programming guide. Which one? Can anyone tell me the biggest differences between the books? Or maybe I have to buy them both... Thanks, Olli
