How exactly do you use a glConvolutionFilter2d() call? I know about convolution filters and kernels, but am not sure exactly how to implement them. Just a simple example with say... a gaussian blur, would be helpful.


That link gives a good description of covolution in general, which I already know. I want to know how to use an opengl call to glConvolute2D to apply a convolution kernel to the window.
