Im having biblical dificulties geting my light system to work correctly, so I''m looking for a Cg tutorial with source code for Visual Studio, that implements a very basic light system, just a dot product between the light and the normals, something extremely simple.

If anyone here has some source code he wont mind providing, i would be most thankful, i''m just trying to pin-point exactly what im doing wrong...

Thanks ahead for any replies.
