Fractal
visionaries:
I named today's fractal pinwheel because there are two versions of
it. In the version I have attached, the rays are beaming
straight
out from the corners. But in another version the rays spiral
out
from the corners, giving the entire figure the appearance of a
pyrotechnic pinwheel.
The formula combines negative exponents, positive exponents and
positive and negative imaginary exponents into a design that looks
quite ceremonial, and holds together surprisingly well.
I have been asked how I color my images. The best answer I
can
give is that I really don't know. I've studied landscape
painting, and that seems to help. But a fractal is an
entirely
new thing that needs new rules. Most often, I simply noodle
around until I find the color bandwidth that seems to work best, then,
when I've found colors that work reasonably well, I fine tune the
palette, sometimes hand adjusting all 256 colors. I've saved
the
color map files of most of my better fractals, but I've found that a
palette that works great on one picture often doesn't work at all on
the next picture.
The four-dimensional animation ideas that are being discussed are quite
interesting. I've been thinking so much about the 4-D
Julibrot
figure lately, that in a vague sort of way I can almost see the entire
monstrous object with its many buds and tendrils. An
animation
would make the monster even more real. But I'm still working
on
finding formulas that will draw all those unimaginably skewed slices.
