Deep Cubic with 5 x 5 anti-aliasing
I have done a lot of exploring in Jim Muth's MandAutoCritInZ formula. Part of the fun is never knowing what you will find. The mixing of the exponents causes the fractal to have a totally different look than the individual z power components. I found this fractal by zooming into noisy areas. The formula is z = 0.9 z^16 - 0.8 z^4 + pixel. A parameter file for the top image is at the bottom of the page. More images in the same area are shown below. The bottom image looks like a robot to me. |
