Fragments of the fractal -like the tip of it

You can just simulate low resolution coordinates:
Code:
double Sphere(double x,double y,double z){
x*=45;
y*=45;
z*=45;
x=int(x);
y=int(y);
z=int(z);
x/=45;//just for clarification
y/=45;
z/=45;
const double a=sqrt(x*x+y*y+z*z)-1;
return (a);
}



I finally was able to remove the discontinuity!
I used a smooth function.
Instead of int I split x in xi= int(x) and the fractional part xf = x-xi. Then I did xf = xf^5*p where p ensures that xf(0.5)-xf(-0.5)=1. Any similar treatment can work if you respect the last condition.
Then I sum back xf and xi and use same method as Aexion getting a smooth DE! smiley Formula m3f is downloadable in my zip.

Looks very good!!  Congratulations!
smiley

Now weave your mathematical magics with Hexes  grin
I have attached is modified a Fragmentarium example (Mandelbox), just zoom.
Two parameters (in the Mandelbox tab): Shape, that going from Triangles, Hexagons and some sort of futuristic bathroom tiles,
and Segments, that is, the number of tile segments..

Have fun!

Is it possible to create several basic shapes and use them both randomly?
