I was working on a custom lighting model a while ago, for use with GLSL shaders and whatnot. I haven't posted anything about it here yet, and I'd like to get some feedback on it before I start making real use of it (using it in applications and such).
I've got an explaination of the model, and a link to the image of the formula here. It's not exactly a professional article or anything, but i'm not a professional . There are also plenty of holes in my knowledge of the math for this stuff too (I really need highschool to be done with so I can move on to these more interesting things), so there's also a good chance I sound like an idiot to those of you who know this stuff well.
