Steam Punk Roller Coaster by HalTenny

Second in this series. I used ABoxSmoothFold2 this time and Integer Power. The steam punk title comes from the overly complicated piping and tubing of course and if you interpret it as I did, it looks like a series of rail carriages or conveyances of some sort are lined up and ready to go.

Man you must spend some time on MB3
I haven't seen a clunker yet!

ABoxSmoothFold2 and ABoxSmoothFold are the same but one version is buggy. I don't know why it has been added, use only the one with this description ... (check it clicking on I button)

WARNING! If you use very high sharpness, I don't know what will happen (it may become
extremely slow)... But it has no sense
An Amazing Box, with Folding function modified as follows (x is each spatial coord);

xp = fix1*x**p; (fast int pow, p is forced to be > 2)
u=sgn(x)*xp;
x=x+xp*(2*Fold-x);
x=x/u;

Also radius folding is smooth (when r<0.99);

r = (x*x+y*y+z*z);
if r>0.99
r=1; // prevents fp troubles and speeds up a lot in this case
else
m

1+minr)/2; n

1-minr)/2; r1

r-m)/n; rs=sgn(r1); r1=abs(r1);
rsqrt = sqrt(r1); // this slows down the convergence
rp=fix2*(rsqrt**p); (fast int pow, p is forced to be > 3)
r = rs*((rp+r1)/(rp+1) * n) + m;
endif

(then r = scale / r and is used as a multiplier for x,y,z)

This "smoothens" the folding function, replacing the "sawtooth" fold with a smooth curve
Result is very similar to standard ABox but with a bit of detail loss and "curvy" details...
Higher sharpness -> You get closer and closer to standard ABox...
Also, remember that smoothing has an interference with the scale. More smooth -> less scale
Inspired from an idea of Buddhi @ FractalForums.
Interesting results can be achieved with negative fix values (more smoothness, different look).

The other one can be buggy

Anyway epic piece
