For those interested in checking out how to program a shader, or even just see what they are about, I found this to be an excellent resource: http://www.catalinzima.com/tutorials/cra...e-in-hlsl/
They dumbed it down enough for me to understand what is going on, and it gives a lot of insight into what these magical things called 'shaders' can do.

Edit: I should mention, this is for HLSL(DirectX) only, although a lot of the same principles (probably) apply.

Thank you, that can come in handy one day
