The Birth of the Easter Mandy

Click "Download" for 1960x1470 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
*a_imag = 0.905
*b_real = #pixel (horizontal)
*b_imag = #pixel (vertical)

Both M+ and M- plotted in separate layers.

No filters or post processing except resizing (from 6400 x 4800).

Ultra Fractal, 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 klippan.seths.se/fractals/arti…

More info about Cubics can be foud at my Cubic Tutorial user.tninet.se/~cim027f/CubTut… and the "cubic" articles in my Chaotic series klippan.seths.se/fractals/arti…
