Looking at last two posts of time tested 2D formulas should be in 3D I just could not to post this possible _modification. It is not an age old time tested formula, posted in december, and found after few beers. http://www.fractalforums.com/index.php?topic=4881.msg39515#msg39515
They say intoxication connects your soul to celestial spheres where information is obtained, but in a dangerous way.
I was trying implementing amazingbox formula together with some variations to play with. Well, this is with bug filled double y no z folded amazingbox, and not with normal amazingbox.
z=amazingbox (z) + c
if |z| !=0
z=z/cabs(z) * complex(-0.1,0.5) + z (division first seems to be faster.)
Positive factor shrunk the fractal, negative bloated it, imaginary value rotated fractal. Alsou modification made fractal more natural floral looking. Quaternionic factor slowed it, so I kept it complex.
And nice julia.
Alsou tested unmathematical things from TMA2.ufm. Round function truncated the render.
z=mandelbox (z) +c;
if round(z) !=0
z=z/round(z) * complex(0,1) + z
Alsou after a mandelbulb formula and factor j=1 got this plant curved bulb.
z=z/cabs(z)* quaternion(-0.2,0,1,0) +z
Yeah, there are just two who can implement, and they don't want to lower quality standarts;) And its pretty time consuming. So just as notice, until there will be no ideas for 249th formula. The code are in mandelbulb and amazingbox http://www.chaospro.de/formulas/display.php?fileid=222
