Hi all

Another question..

I used to generate images using a home-made C++ application, in which I was
able to simulate a Point-Spread-Function (doing a convolution with a square
kernel of a gaussian form).

In other words: when I was done constructing my image, all I needed to do is
to build a square kernel, say 5x5 pixels, filling it with a gaussian form.
Then, I applied this kernel to the image using convolution. This way, I
could achieve to simulate a blurring effect.

My question is, can PovRay do something like that? I thought of the
"focal_blur" keyword.. is it gaussian? is there a way to create our own
kernel?

Thanks!
O.
