FOTD -- September 30, 2011 (Rating 8.5)
Fractal visionaries and enthusiasts:
Today's image is a scene deep in Seahorse Valley, where the
elements are of extremely high iteration. Even today's maxiter
of 600,000,000 leaves some open areas outside the central
minibrot. This extreme maxiter also makes the calculation
frequently appear to hesitate. This is normal.
With iteration counts and maxiters like today's, the logmap
options are basically useless, producing nothing but flat areas
of color. Shutting off the logmap results in an image with too
much trashy chaos. The 'tdis' option would probably do better,
but it does not use the fireball-fast machine language of the
type=mandel formula, and would require many hours to finish.
I compromised by rendering the image with the outside set to
'real', which adds enough detail to make things interesting,
cuts the trashy chaos a bit, and still uses the fireball-fast
math.
The rating of an 8-1/2 includes the standard half-point for the
coloring.
The name "My Name Is Fractal" refers to the image, not myself.
The calculation time of 21 minutes is on the slow side, but the
time will seem to pass quicker once the brilliant colors appear
at the top of the screen.

A mix of clouds and sun, and a temperature of 68F 20C made today
an acceptable one here at Fractal Central. At least, the
fractal cats thought so. They spent a lot of time in the window
that serves as their TV, watching for stray cats passing by and
squirrels gathering nuts.
FL and I, the local humans, spent the day doing what needed to
be done. The next FOTD will be posted in 24 hours, most likely
a trip into the 4-dimensional Julibrot. Until then, take care,
and there are 4 regular concave polyhedrons in 3-dimensional
space in addition to the five well-known convex Platonic solids,
for a total of 9 regular 3-dimensional polyhedrons.
