I used a section of the screen and the buffer to pre-calculate the positions of each generation of spheres. The colorful garbage you can see on the lower part of the image is the pre-generated data. It was kinda tricky to properly write and access the right pixels of each generation of spheres, but I think it's working fine.

Pushing the shaders to the limit! Nice work, Kali!

I looked for optimizations but I still don't know how it works

The buffer is opening up new strange doors for you. Can't wait to see whats next.

Here are some fragmentarium scripts rendering simple 2 generators IFS using stackless tree traversing:
SimpleIFS2D-final.frag: Computes DE in 2D.
SimpleIFS-DE3D-final.frag: same in 3D.
SimpleIFS-RT-final.frag: ray-traces the IFS in 3D. More like what David Makin was describing.
SimpleIFS-OT-RT-final.frag: Same but with orbit trap spheres.

I'm pretty sure someone will improve and extend them. embarrass

Have fun!
