Fast Gaussian blur

Does somebody have a fast gaussian blur code that let me specify the kernel seed similar as the one in the gimp. This is for real time so it better be fast hehehe

Some interesting articles on Fast Gaussian blur filter techniques:

2 very fast Gaussian blur implementations w/ code:

Yeah I found the same thing using google but none of them convince me... tks anyway...

Could it be possible to ghost copies of a mesh (with incremental alpha loss), and create a per mesh "blur effect" ?

I think render to texture is the only way... (that's what Im doing...)

I'll experiment on my side, i'm trying to create effects without accessing the render buffer... (mainly through vertices and going through scene graph)... we'll see how that turns out...

well its like 100% sure that it turns bad cuz you are going to overload the GPU with vertices... you really better get access to the color buffer or render to texture...
