Generic GLSL Lighting Shader?

I would strongly suggest you to read this article to see how the standard ADS lightning is done within GLSL. That is GL 4.0 but not a problem to adjust to your version.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
