Using a convolution matrix in shader forge

Brad Hammond fa 9 anys updated by Fabio Franconeri fa 8 anys 2

I've started playing with Turing patterns and using convolution matrices and came to realize this is how a lot of different filters are done.

I was wondering if there is a way this mothodology of sampling neighbor pixels to the current one can be implimented in shader forage?

It's possible but very cumbersome to make, at least if you have a large matrix.

But yes, just shift the UVs and sample again, and do whatever you like with the result!
