Dark Brotship

Download for 1280x960 resolution

Magnification in a 2D-slice of the four dimensional cubic parameter space using the standard parameterizing z -> z^3 - 3a^2 z + b, critical points z = +a (making the set M+) and z = -a (making the set M-).

*a_real = 0.005
*a_imag = #pixel (horizontal)
*b_real = #pixel (vertical)
*b_imag = 0.005

The sets M+ and M- is drawn in separate layers

No filters or postprocessing except anti-aliasing (from 6400 x 4800).

Software: Ultra Fractal.
Color routine: Continuos Potential Method (CPM).
Formula: Cubic Parameterspace3 in the sp3-module written by my dear friend Stig Pettersson, Greenseng here at DeviantART. All his modules, as well as mine can be downloaded from [link]

More info about Cubics can be found at my Cubic Tutorial and the "cubic" articles in my Chaotic series.

Below the parameter file. Play and have fun
