Fractal
visionaries
and enthusiasts:
Due to the unusual colors of today's image, I wanted to rate it higher,
but I just couldn't shake the feeling that I had seen something similar
so many times before. It takes more than just colors to make a
great fractal image, so I finally settled for a rating of a 6, which is
slightly above average.
The generating expression combines 1.5 negative portions of Z^(0.6)
with 0.25 negative portion of Z^(6.4) and then adds (1/C). The
parent fractal is an area of scattered Mandelbrot sets with different
degrees of distortion, all of them surrounded by clouds of smaller
satellite M-sets, all the way to infinity. Today's scene lies in
a satellite of a satellite very deep in what appears to be an East
Valley of one of the largest M-sets.
The name "Galaxial Attraction" means next to nothing. It's
probably a carry-over from my wonder years, when I wanted to be an
astronomer.
Due to the extreme magnitude of the image, the mathtolerance entry in
the parameter file is absolutely necessary. Without it, all kinds
of weird things happen. The image actually lies beyond the range
of perfect resolution, but the resulting breakdown is hardly noticeable.
The calculation time of 1-1/2 minutes is a fair price to pay for
today's image.
The temperature rose to 88F 31C in the early afternoon on Monday here
at Fractal Central. At 4pm however a thunder-storm moved in with
a gust of wind and a brief downpour of rain. By 5pm the
temperature was a comfortable 73F 23C. The storm dropped 1.5cm or
just under 1/2 inch of rain, much to FL's satisfaction, but the rain
here is still about 25cm or 10 inches below normal for the year.
The fractal cats braved the storm without dashing for cover.
The next FOTD will be posted in 24 hours. Until then, take care,
and every fractal should exceed the one before.
