pixel processor for loop?

electricsauce · Aug 2015

Is it possible to create a for loop inside of the pixel processor? I'm trying to iterate through an input texture so that I can get a value for each pixel and compare it to a stored value.

There is currently no way to make a loop in a function graph. It is not easy to find a way to setup a proper graph layout to allow for that (we can't allow "graph loops"). Also, we would need a way to check for infinite loops in advance in order not to lock the CPU or GPU in case the user sets up a loop incorrectly.

Ok, I'm going to have to get creative then.

Think of your texture as one big pixel, and do the exact same operations. That should work.
