Trying to play with the raw image data is hard

u/cshadows

wow!!
u/tomxor

It is hard - shame there isn't a simple buffer to write to
u/nburn42

I wanted to build cellular automata based off raw data, but there is so much overhead involved.
u/nburn42

I'll try anyway.
u/tomxor

What do you mean by raw data? using the frame buffer for state? there are quite a variety of CA implementations here but they are mostly tagged gameoflife regardless of specific rule. I made a larger than life one recently that is capable of >1 radi moore neighborhoods
u/nburn42

I see some of your CA, the are awesome, I'll play around with some of your methods too.
