(or real universe is flat, however, so if God were to build 4D sponge and swing it through our world you would see David sponge, not this).
Even if you get closer to relativistic speeds? Very nice stuff

:- The site xs.to is down. Anyone can do a quick render of this thingy? Looks very similar to the "NewMenger" fractal.

Replace fmod (x*p, 3) with x*p % 3 In first entry of this thread gives the following Gestaltlupe formula: public override bool GetBool(double x,double y,double z) { // pick w at any hyperplane crossing unit hypercube double w = 1 - x - y - z; int iterations = 7; if ((x<0)||(x>1)||(y<0)||(y>1)||(z<0)||(z>1)||(w<0)||(w>1)) return false; double p = 3; for (int m = 1;m < iterations; m++) { double xa = x*p % 3; double ya = y*p % 3; double za = z*p % 3; double wa = w*p % 3; if (/* any two coordinates */ ((xa > 1.0) && (xa < 2.0) && (ya > 1.0) && (ya < 2.0)) || ((ya > 1.0) && (ya < 2.0) && (za > 1.0) && (za < 2.0)) || ((xa > 1.0) && (xa < 2.0) && (za > 1.0) && (za < 2.0)) || ((xa > 1.0) && (xa < 2.0) && (wa > 1.0) && (wa < 2.0)) || ((ya > 1.0) && (ya < 2.0) && (wa > 1.0) && (wa < 2.0)) || ((wa > 1.0) && (wa < 2.0) && (za > 1.0) && (za < 2.0)) ) return false; p *= 3; } return true; }

The David Sponge Variant: double w = 1.5 + x - y - z

Your program is great. The absence of de is great to create more freely shapes...

Thank you.
Here is: double w = x + y

Looking good and sharp images. Looks like there is a lot to explore. my fragmentarium DE version attempt is debugged of syntax errors but produces nothing. I will next try it using DelatDE in mandelbulber.

Yes, but visually, it is very sad and scary
