Sept. 9, 2012: Oblate Rectangle | Sept. 8 | Sept. 10 | 2012 | FOTD Home |
Fractal visionaries and enthusiasts:
We
have found the
strange Z^(2.003)+C rectangle in the Julia sets and in the Mandelbrot
set. But what about the four remaining perpendicular
directions
through the Julibrot? Well, as today's image shows, the
rectangle
also appears in the Oblate orientation, where, with the proper
stretching and skewing, it makes quite a striking appearance.
At first glance the image appears to have origin symmetry, but a close
inspection will reveal that the symmetry is only apparent, and not
exact.
I named the image "Oblate Rectangle" for the obvious reason.
The
rating of a 7-1/2 includes the usual bonus for my coloring work, which
creates a good part of the overall effect.
The calculation time of 3-1/2 minutes might seem slow to those who are
growing bored with rectangles. The web sites bring total
relief
from boredom however.
The next three FOTD's will feature the rectangle in its remaining three
aspects. Then we'll move on to other fractal wonders.
A near perfect day prevailed here at Fractal Central today, with a
temperature of 75F 24C and a Photoshop (aka Kodachrome) blue sky dotted
with small, puffy white, chamber-of-commerce cumulus clouds.
The
fractal cats enjoyed the outside conditions from inside, spending much
time on the shelf in the southwest window, where the sun, at its lower
angle, is again starting to come in.
The humans made it through the day without incident. The next
FOTD image will be posted in 24 hours. Until then, take care,
and, if the world is a dream, then the evidence that it is a dream is
also a dream.
