Hidden world or more like a snail with a suction foot and gooey insides

Hi

Ok, I modified the mandelbulb equations to scale r,theta,phi independently as r^Na, Nb*theta, Nc*phi...
It is amazing!! what stuff you can find then changing these values shocked

Try Na=-2.0 Nb=2.0 Nc=2.0 and you will see a gooey world inside grin

You can also see my attempt to show this here (my renderer is poor):

nice... maybe something with less transparency would work better though

Hard to make out anything specific

This is the variant that wouldn't be possible with non-spherical formulae I guess, as negative radius is something impossible^^

(although... actually it should be possible by just converting the spherical coordinates with signed radius back to euclidean. this would be equivalent to rotate the whole thing 180° in each step^^)

The radius is not negative r^-2 is the same as 1/r^2 just inverse.

A mandelbrot analogy with Zn=r_n*exp(i*theta_n) would be

Zn+1 = (r_n)^-2 * exp(i*2.0*theta_n) + C

Thus keeping ordinary sign on 2.0 for the angle..but not for the scaling.

I wish someone with better rendering programs..could render this one tongue stuck out

Ill try less transparency..but i am new to this.. first volume rendering for me.
