Subject: (fractint) C-FOTD 29-06-01 (A New Seahorse [7])
Classic FOTD -- June 29, 2001 (Rating 7)
Fractal visionaries and enthusiasts:
Midgets are found everywhere around the border and along the
filaments of the Mandelbrot set. Some of the best midgets are
found in East Valley, sometimes known as Elephant Valley, and in
the two symmetrical valleys on the west side of the lake, known
together as Seahorse Valley. Today's image pictures a typical
though rather deep midget lying in Seahorse Valley.
So far, so good. The image is filled with the seahorse tails
typical of this area, and all the expected features surround the
midget in the 2,4,8... series, without being cut off, just as
they would be expected to do. But things go awry as we approach
the actual midget at the center.
Where there should be a minibrot, we find a roughly triangular
hole, which has little resemblance to either a midget M-set or
to a hole in a Julia set. Something strange indeed is going on.
At first glance, one might suspect that the image is part of a
perturbed Mandelbrot set, and that the fully-formed midget will
appear if only Z (p3) were initialized to 0,0. Unfortunately,
doing this results in a screen filled with diagonal lines, with
no midget anywhere in sight. So what is going on?
True, the image is perturbed, but it is not a Mandelbrot set.
The answer lies elsewhere.
The Mandelbrot sets and Julia sets are perpendicularly oriented
slices of an abstract four-dimensional figure known as the
Julibrot, only parts of which can be seen in our three-
dimensional space. And four-dimensional objects can be sliced
by two-dimensional planes in six mutually perpendicular
directions. Today's picture shows a midget sliced in one of the
odd perpendicular directions.
Mandelbrot sets display the C plane, Julia sets display the Z
plane. Today's image displays the plane determined by imag(C)
and imag(Z). I have named this orientation 'Rectangular',
because the slice in this direction through the origin of the
Julibrot shows a roughly rectangular lake.
If one wishes to call these slices 'Rectangular sets', very
well. Though don't expect the midgets to be shaped like
rectangles unless the slice cuts them exactly through the point
that corresponds to the origin of the Mandelbrot set, and they
happen to lie in the same orientation.
In addition to the Rectangular direction, there are three other
new directions, as well as an unlimited number of oblique
directions in which to slice the Julibrot. And every new
direction shows a new and unique aspect of the Julibrot. During
the upcoming month of July, I'll be exploring these new
directions.
I named today's image "A New Seahorse" because though it is a
scene in Seahorse Valley and is filled with sea horses, the
midget at the center is unlike anything seen in the standard
Mandelbrot or Julia views of this area. I rated the image at a
7, mostly because of the striking coloring.
The parameter file takes only 3-3/4 minutes to render on a
Pentium 200mhz machine. The already-rendered GIF image
downloads in even less time. That GIF image may be found posted
to:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
and to:
<http://sdboyd.dyndns.org/~sdboyd/fotd/index.html>
But give Paul and Scott a chance to post it before visiting
their sites.
The fractal weather today (June 28) brought the first really hot
day of the season, with a temperature of 95F (35C), and all the
haze and humidity that goes with such heat. The fractal cats
had no complaints, though they showed little activity in the
sweltering conditions.
Tomorrow (today, June 29) promises to be just as hot, so I'm
going to take it easy and let the CPU do all the work. Until
next time, take care, and when the going gets hot, get going on
a hot fractal.

Is that the 20.0 version from the Spanky Database at:
http://spanky.triumf.ca/www/fractint/fractint.html
Or the 20.1.12 version from the Development Team's site at:

Personally, I would keep it within the same directory path as the

After you get the initial default image upon starting FractInt, use the
"x" option to take you to the "Basic Options" screen. Amongst the may
values that may be set, you will see these four with their values:
Inside Color 1
Inside numb
Outside Color 0
Outside iter
Try modifying the above to the following values:
Inside Color 1
Inside bof60
Outside Color 0
Outside numb

None of which has to do with their "discovery", but drawings (by hand) of
fractal structures were being published a century ago, as well.

No, because "lists of numbers" would be irrelevant to understanding the
maths; although they were enough for Edward Lorenz to see something was up
in his weather modelling, they couldn't tell him what.

If you start with z0=3D0 you get:
z1=3Dc
z2=3Dz1^2+c =3Dc^2+c
z3=3Dz2^2+c=3D (c^2+c)^2+c =3D c^4 + 2*c*c^2+c^2+c =3D c^4+2*c^3+c^2+c
etc.
Now we can ask, "what values of c will give z3=3D0 =3Dz0", these values =
of c are
the

Just to clarify, the union of all these sets isn't M, but it does =

Subject: (fractint) C-FOTD 30-06-01 (Head of Zardoz [4])
Classic FOTD -- June 30, 2001 (Rating 4)
Fractal visionaries and enthusiasts:
Today's image is another view of yesterday's midget. Of course,
yesterday's image was not a picture of a midget, it was a slice
through a hole in a four-dimensional object known as the
Julibrot. Such slices are known as midgets only when the slices
are oriented in the direction determined by real C and imaginary
C, and the starting point of Z is 0,0. Under these conditions
the holes appear as miniature versions of the entire Mandelbrot
set.
When the orientation of a slice is changed, or the starting
point of Z is set to a value other than 0,0, a slice will not
cut a hole in a miniature M-set. The slice of the hole will
appear as a Julia set or as an irregular open area. True, some
of these slices come very close to being intact mini-M-sets, but
there is always some tiny imperfection when one searches deeply
enough.
When cut in an odd direction, (other than Mandelbrot or Julia),
a hole often presents an irregular triangular shape, as did the
hole in yesterday's image. But in yesterday's image the pattern
around the hole was intact. In today's slice of the same hole,
the pattern has been distorted and stretched in three directions
until it is barely recognizable. It is apparently the same
three-way distortion that shaped yesterday's hole, but this time
it affects the entire surrounding area.
This three-way stretching appears quite often around holes when
they are sliced in odd directions. There must be some geometric
feature of the Julibrot causing the effect, which would be quite
apparent if we could visualize four-dimensional forms. In
today's scene the hole itself has been reduced to a narrow slit.
This also happens quite often in the odd slices, and is due to
the unusual shape of the actual hole, which has two extended Z
dimensions and two much smaller C dimensions.
I named today's image "Head of Zardoz". Anyone who knows the
movie, which features a flying head, knows why I chose the name.
I rated the picture at only a 4. The twisting, stretching
effect is really rather unattractive, and I chose it only to
show what could be done by rotating the direction of the slice,
while keeping it centered in the hole. I also kept the same
palette of colors as an aid in identifying the same features.
Taking an even 4 minutes to render, the image is mercifully
convenient to render from the parameter file. Downloading the
GIF image from:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
or from:
<http://sdboyd.dyndns.org/~sdboyd/fotd/index.html>
is equally convenient. But give Paul and Scott a chance to post
the image before trying.
The fractal weather today continued sultry. The temperature of
90F (32C) and occasional distant thunder kept the cats alert.
But all went well. No storm broke and the cats finally relaxed.
And it's about time for me to relax. It's 10am on a Saturday
morning, with other stuff to do. But I'll be here again, right
on time with the next FOTD. Until then, take care, and though
we can speak the words about the fourth dimension, we cannot
picture what we are speaking of.

But if you just plot all the points in all those infinitesimal bays,
together they will appear like an outline of the Mandelbrot set (a kind
of dust that grows ever denser near the "shoreline", similar to the

But there is only one root per bay so you will see an outline of the
manelbrot set but the shore line will not be defined, only a dot for each
small bay and there are many small bays on the shore line.
