Fractal Of The Past - 006
You can click on the thumbnail image
above to see the image at size 640 x 480.
The type of this fractal is Julia.
I started with the Mandelbrot fractal. The next
sequence shows how I zoomed in to get the 'root' for the Julia fractal:





The crosshair in the previous image indicates
the "root" for the Julia fractal. In Fractint you get this by just pressing the
spacebar.
Pressing the spacebar again brings up the julia fractal.
I changed the outside option to 'summ'.
Next I applied the Inversion option (on the 'Y-xcreen' in Fractint).
Basically this turns the image inside out. In the previous image you can see the center of
the inversion, indicated with the crosshair.
Finally I choose a color map.
For Ultra Fractal there is also a general inversion formula,
written by Damien Jones (click on 'mapping' in the properties window and look for
'general inversion' in file 'dmj'). It is a transformation formula with much more
options than the inversion option of Fracint. But in both cases it is a very effective
tool to make interesting images out of ordinary fractals.
