This is exactly the same motive as the previous CubicBudCompass [link] . Nad the comments below are also exactly the same

This is my very first published fractal motive from heptic parameter space [link] (see the linked journal).

*a_real = #pixel (horizontal)
*a_imag = #pixel (vertical)
*b_real = 0.5
*b_imag = 0
*c_real = -0.5
*c_imag = 0
*d_real = -0.5
*d_imag = 0
*e_real = 0.5
*e_imag = 0
*f_real = 0
*f_imag = 0


The black area in the middle is (a 2D slice) of Heptic Connectedness Locus (HCL), the set for which ALL the six critical points has bounded orbits. The fractal border of HCL is formed of M1 and M6 that completely coalesce in this slice. The borders of M2, M3, M4, and M5 also completely coalesce in this slice and form all the outer fractal borders (including the islands).

This motive came up as one of the big surprises from the heptic (7th) degree) parameter space. It’s like the cubic compass [link] (see also figure 1 in [link] ), which also occurs in pentic parameter space, see [link] , and as we shall see later here in Heptics also. But here the buds of the outer circle are Cubic Mandelbrot buds having (of cause) Cubic minibrots in their filaments. The islands that surrounds the compass is also made up of cubic mandys (we will see that later).

Note: This motive is a one layer image drawn due to HCL + SetBorders visualizing all the sets in one layer.

Instead of the basic coloring (coloring according to the number of iterations) a evaluated form called Continius Potential Method (CPM) is used. This method produces continues slopes around the sets instead of discrete plateaus.

No filters or post processing.

Below the UF parameter file. Play and have fun
