Fractal
visionaries
and enthusiasts:
POSSIBLE NEW FORMULA ALERT! I might not have previously
posted
the Mandel-V-Esc formula, which allows changing of the bailout
radius. I'm not sure.
Today's rather weird image involves a couple tricks. The
image
itself is located in the East Valley of the large minibrot at -1.75 on
the main spike of the Mandelbrot set.
The first trick is rendering the image with the 'outside' set to
'real'. This adds the intricate detail to the scene.
The second trick is coloring the image with a random color palette,
though I did do a bit of tweaking to tone down the randomness at least
a bit. This creates the frantic madhouse effect that inspired
the
name "Madhouse".
The third and greatest trick is setting the bailout radius to the point
just before the image gets cut off and goes blank. In today's
case this point is 3.079. To see what this does, calculate
the
image with the real(p3) parameter set to 4, or even better, set it to
100.
All these tricks add up to a rating of 7.5, not bad, but far from the
super 9.5 images of last month.
The calculation time of one minute is unexpectedly brief.
Part of
the briefness is due to the fact that the points are beyond the bailout
radius almost as soon as they get started. The large flat
areas
also increase speed by making the passes=guessing option more efficient.
Over two inches, 5cm, of rain fell overnight Sunday here at Fractal
Central, Monday remained cloudy, with occasional rain and a temperatre
of 73F 23C. The fractal cats, unconcerned with the weather
and
forecasts of much more rain to come, found their day's excitement by
chasing each other in and out of the laundry basket. The
humans,
never short of things to worry about, spent the day wondering what the
future holds.
For better or worse, the next FOTD will be posted in 24
hours.
Until then, take care, and even Bozo the Clown could run the world's
fast-fading superpower better than the present loser and the losers
lined up to replace him. Why not elect Bozo. At
least we
would go down laughing.
P.S. -- The evil ______________ is/are responsible for the country's
troubles. (Fill in the blank with your favorite scapegoat or
goats.)
