Per Pixel Lightning : the same problem but with source code

OpenGL OpenGL: Basic Coding

When I use PPL, the textures are black, for me it’s a belding problem or a multitexturing problem.

Now, the source code is available to download so I hope that it will be more easy for you to try it.

F ==> Moving the light toward Z
V ==> Moving the light to you
D ==> Moving the light left
G ==> Moving the light right

You can download the source code here :
