pixel by pixel graphics, what's the name of this technique?
A few days ago I was talking with a demo scene enthusiast and he mentioned this piece of software that runs a given function on every single pixel of a bitmap at a given framerate rate, 30fps for example.
He refered to it as a 'shader' but wikipedia has a different definition for 'shader'. What's the name of such a program?
It appears to be rather trivial to implement, should also be quite easy to parelelize in a gpu with modern technologies such as CUDA.
