Just for fun....
I was reading the great site from Paul Bourke this morning, particularly the page about the fractals, and reached this one : Solenoid fractal.
Looks like a challenge to create the same kind of rendering using G'MIC, no ?
Finally, I managed to do it, with this fun and unreadable again G'MIC code snippet !
which works only with the latest pre-release version of G'MIC, numbered 2.0.0_pre (for those who want to test!).
And using the integrated 3d renderer, I've got these images (tweaked a bit the colors).
Isn't that nice ?
Yes, that is also totally useless (and thus totally indispensable?).
