Playing with Fragmentarium, using a formula I called SurfaceIFS (x,y folds + scale + rotations)

Sorry for the low quality, but HD could take ages to upload with my shitty internet connection :sad1:

Looks like a lot of fun! O0
I have to try it out!

love the vid but you couldn't give us one screen shot of the formula?!?!

Nice, love the napkin to fungus flows.

Ok, here's the DE... Julia, Scale, Fold, RotVector and RotAngle are the parameters:

Code:

float DE(vec3 pos) {
	 rot = rotationMatrix3(normalize(RotVector), RotAngle);
	vec3 p = pos, p0 = Julia;
	
	int i=0;
	for (i=0; i<Iterations; i++) {
		p*=rot;
		p.xy=abs(p.xy+Fold.xy)-Fold.xy;
		p=p*Scale+p0;
		if (i<ColorIterations) orbitTrap = min(orbitTrap, abs(vec4(p.xyz,0)));
	}
	return (length(p))*pow(Scale, -float(i));
}

Thanks for the comments

P.S.: Sorry about the music, Chris!

if i get fragmentarium code as apology, i cant be upset ;)

:ok:

This is the full .frag file of a render using this formula, had to rename it to .txt because it says .frag files are not allowed

Very nice. I love the tree structures that popup with these formulas.
I explored a few here: https://vimeo.com/34659879

i include .frag in the allowed file types, thank you

dude this is a way cool script, amazing transforms.... gotta play with fragmentarium, and type in some own formulas ... ;)

Thanks for the comments. This is obvioulsy nothing very new, but a variant of knighty's KIFS, and also similar to Mandelbulb3D genIFS formula (but the folding is different).
I just like how it develops from a plain 2D surface to a complex surface or solid fractal. Try it also with Tglad's boxfold on x-y axis.

subblue: great video, I just got a similar object by using abs and conditional swaping of x-y values... I attached the image.
