Welcome to Tutorial 9. By now you should have a very good understanding of OpenGL. You ve learned everything from setting up an OpenGL Window, to texture mapping a spinning object while using lighting and blending. This will be the first semi-advanced tutorial. You ll learn the following: Moving bitmaps around the screen in 3D, removing the black pixels around the bitmap (using blending), adding color to a black & white texture and finally you ll learn how to create fancy colors and simple animation by mixing different colored textures together.



We ll be modifying the code from lesson one for this tutorial. We ll start off by adding a few new variables to the beginning of the program. I ll rewrite the entire section of code so it s easier to see where the changes are being made.
