About lighting (not OpenGL lighting, but general lighting)

I wanted to do all my lighting in my program, but I wanted more information about the different light models and the equations for each one. I was reading/trying to understand the chapter on lights in the Computer Graphics: Principles and Practice book with little success. Are there any other resources out there? I found little information in Google, maybe you can correct me…

Thx!

Im also interested in this.

The general OpenGL formulas are on the specs. All you need to understand is dot products and vector calculations.

The Foley and van Dam was a good choice. Try to get the grip on it.

I liked Alan Watt’s 3D Computer Graphics.

A very interesting reading but pretty advanced (you have been warned!) is “Roy Hall: Illumination and Color in computer generated Imagery”.
