That's awesome, can you post a link to your 3D Kaliset formula please?

Thanks asimes. Kaliset formula is used here for texturing the fog, using exponential smoothing calculation method.

For the basic formula version, iterate for every point p:

p=abs(p*scale)/length(p)²+c

or...

p=abs(p*scale)/dot(p,p)+c

c is a constant (or julia value), use negative ones, and try with different scale values.

The fractal itself is the Kalibox, a Mandelbox mod you can find in Mandelbulb3D as "AboxmodKali":

This is copied from the formula info in M3D:

Code:

x = X_add - abs(x)
y = Y_add - abs(y)
z = Z_add - abs(z)
rr = x*x + y*y + z*z
if rr < sqr(Min_R) then m = Scale/sqr(Min_R) else
if rr < 1 then m = Scale/rr else m = Scale
x = x * m + Cx
y = y * m + Cy
z = z * m + Cz

as my commenting machine in the gallery seems to be broken, I comment here.

This is fantastic Kali. The atmospheric density you created here is just breathtaking. Images like that are one of the reasons I voted for you in the fractal noble oscar (what a stupid name). Fragmentarium rocks, when used by a sage!
