Shaders to jit.gl.pix - How to deal with feedback? (iChannel0, etc.)
Sep 11 2016 | 2:47 pm
Recently I've been interested in porting Shadertoy shaders, especially game of life and reaction-diffusion kind of systems that use feedback.
By reading up on the Shadertoy examples and this patch with ported Shadertoy tuts, as well as Syrinx' great overview of what one needs to change when porting shaders (last post in thread) I've gotten quite far.
One thing I'm wondering is how to deal with the feedback. I'm trying to port this shader "Vicious Fingering", and running into problems. I tried to figure out how to deal with the feedback by looking at some jit.gl.pix examples like jitter-examples/gen/pix.game.of.life and examples/gen/reaction.diffusion.color.world. those use a combination of [zl reg] and jit.gl.slab, but I haven't been able to get that to work for this one. What am I doing wrong?
