Cool, I recently started with GLSL, and it’s interesting there are many roads that lead to a similar solution (how I draw circles or make a center is tad different)

Where or how did you learn GLSL?

I was around and writing OpenGL when we started getting the first programmable cards. Nvidia shot out first with their Cg language, but I held back and waited for the "Orange Book" to come up. I bought it right away and learned from it and by looking at other peoples shaders.

Also the quick reference card helps

So you are a veteran, compared to me, just started this year, really reminded why I should have been more observant in math class :)

The resources are really good, hadn’t found something like that yet!

Small correction, NVidia Cg was only the first on PC.

We had Renderman on NeXT, TI TMS34010, and a couple of other attempts outside the PC world.
