FOTD -- April 20, 2000  (Rating 6)

Fractal visionaries and enthusiasts:

Today's fractal is a true blast from the past.  It's a blast
because it shows a midget caught in the act of exploding, and
it's from the past because it first appeared on the Fractal-art
list way back on May 9, 1997, in the very early days of the FOTD.

I notice from the reset=1821 in the parameter file that the
image was calculated by the version of Fractint that came
packaged with the second edition of "Fractal Creations", a fine
book on fractals, authored by our own Tim Wegner, supreme
moderator of the Fractint list.

As one might suspect, I spent a bit of time this afternoon
browsing through those old FTOD's.  I was surprised at how fresh
some of the oldies still look.  I'll repost the best of them
occasionally.

I named today's picture "A Blown-up Midget" because that name
quite accurately describes the scene.  Not only is the midget
blown-up by a magnitude of many millions, it also appears to be
caught in the act of exploding.  The expression behind the
explosion is a very simple Z^1.6+C, which has been calculated by
the built-in manzpower formula.

The blast takes 18 minutes, so I'd recommend downloading the
JPEG image from:

          <alt.binaries.pictures.fractals>

or from:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

unless you want to risk blowing your top while you wait for the
parameter file to run.

The fractal weather was cloudy and chilly in the morning
followed by sunny and mild in the afternoon.  The temperature of
66F (19C) was just warm enough to lure the fractal cats onto the
porch, where they perused the area for over an hour.

The day was somewhat busy, leaving me little chance to ponder
the deep mysteries of existence.  But another wave of wisdom is
building, and when it arrives the world will be that much the
better.

Until next time, take care, and a fractal a day keeps the blues
at bay.

Oh, I know; I was just saying that, whatever Fractint _can_ do, there will
always be someone who can look at it, think for a bit and then say "Hey,
what about....". After all, isn't that pretty much what's happened?

Okay then, I do have a specific request, and the code is virtually all
there already. Basically, as well as being able to run user formulas as
standard escape-time fractals, add a new type for running them as dynamical
orbits. To draw a parallel:
popcornjul <-> popcorn
    mandel <-> mandelcloud
   formula <-> *dynaform* (or some such name).

The parameter entry screen would have the "#0 of intervals..." field added
after all the usual user parameter fields, and the bailout of the formula
would be ignored. Many of the formulae I've collected look better rendered
this way, and I've only added simple bailouts so that they work as
escape-time fractals (though usually boring ones). I've hung on to them in
anticipation that this type would eventually be implemented.

Does this sort of thing make sense? This is really wishlist material I
suppose, but I was just wondering if anyone else plays with these types
enough to make it worthwhile.

FOTD -- April 21, 2000  (Rating 4)

Fractal visionaries and enthusiasts:

All my FOTD fractals are single layer.  This is a self-imposed
limitation, not a limitation Fractint, which can create quite
effective 2-layer images for those who prefer more than one
layer.  I mention the layers because a quick glance at today's
fractal image gives the impression of more than one layer.
This impression is an illusion.

The brilliantly blue midget near the center is obvious enough,
but behind the midget, lurking like a ghost in the shadows, lies
a far greater Mandeloid.  The curved shoreline and one bud of
the ghost-brot are vaguely outlined by the blue areas of the
background.

The overall scene is filled with floating ectoplasm-like
fragments of fractal material.  Such fragments are typical of
fractional exponent fractals of an order between zero and 2.

The formula that found the ghost is once again the
MandelbrotMix4, this time calculating Z^1.9+Z^0.3+C.  The
parameter file is a slow one, making a download of the image
almost a necessity.  If Mindspring gets its news server back
online, that image will soon be posted to:

          <alt.binaries.pictures.fractals>

and to:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

Otherwise it will not be posted until tomorrow.

The fractal weather today was partly cloudy and mild, with a
temperature of 65F (18C), which made the cats happy.

The philosophy floundered today.  I'll try again tomorrow.
Until then, take care, and the best fractals are yet to come.

Hi,
unless you want to point to a particular file
(no wildcards) just point to the subdir names
- - but without the backslashes at the end.

Subject: (fractint) FOTD, 22-04-00  (Spiralling Inward [2])

FOTD -- April 22, 2000  (Rating 2)

Fractal visionaries and enthusiasts:

Today's fractal non-wonder rates a much-below-average two on my
0-10 scale of fractal worthiness.  I gave it so little effort
because I'm annoyed.  The mighty Mindspring-Earthlink conglomer-
ate, which claims to be threatening to take over AOL's position
as number one, is once again down for the count, and unless I
place a long-distance call I cannot access their news server to
post the image.

The M.S. Tech support says to be patient, that it's not their
fault.  I say of course it's not their fault -- it never is --
it just happened.  But whether they're to blame or not, the
result is the same.  The situation is humorous because I can
still access the Mindspring mail server by using the network of
their arch-rival AOL.  Too bad this doesn't work with the news
server, which replies, "access denied".

The FOTD image is a routine spiral in the fractal created by the
formula Z^2.4142+Z^0.4142+C.  0.4142 is the reciprocal of
2.4142, though I doubt if this plays any part in the image.  I
named the picture "Spiralling Inward" for descriptive reasons.

The parameter file takes just under 10 minutes on a modest
Pentium.  And running the parameter file is the only way to view
the image, unless a miracle happens and Mindspring gets its act
together.

If it does get its act together, the image will be posted to:

          <alt.binaries.pictures.fractals>

and also be available at:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

If not, rev up the old Fractint engine.

The weather today was as exciting as today's fractal is dull,
with occasional heavy rain showers and one of the noisiest
thunder-and-hail-storms I have ever observed.  The explosive
thunder and crashing hail frightened Thomas, the fractal cat,
who ran and hid under the fuel tank in the basement, and came
out 1/2 hour later covered with grimy soot.  Tippy braved the
tempest under the bed.  The temperature of 63F (17C) was
comfortable enough, but the wetness kept the cats indoors.

The philosophy is brewing quite nicely, in fact, it might
appear as soon as tomorrow.  Until then, take care, keep wishing
and be patient.

Yes, that is correct, but it really doesn't matter whether it ends with
a slash or not, it will work either way.

Mmh,
in my case (DOS/Win) this only works if the
backslash is not the last character before
CR/LF, because then Fractint wraps around to
the next line, concatenates this string to the
first and complains...

Gerald

Interesting, I've had the backslash on mine for several releases of
Windows/DOS and FractInt.  I currently have it running on four of my
machines in this manner:

    486-DX     Windows 3.11 (workgoup)   FractInt 18.2 thru 19.6
    P-90       Windows 95 (original)     FractInt 19.6
    P-200-MMX  Windows 98 (original)     FractInt 19.6
    PIII-750   Windows 98 (rel. 2)       FractInt 19.6 thru 20.0.11

I've always used Notepad to edit the text file on all of these
machines.  Here are just some of the lines from the last one on the
list:

Subject: (fractint) FOTD, 23-04-00  (Ejecting Minibrot [6])

FOTD -- April 23, 2000  (Rating 6)

Fractal visionaries and enthusiasts:

At last, Mindspring has recovered from the fire in the Washing-
ton, D.C. subway tunnel, and things are back to normal.  So it's
time for the next glorious fractal to appear.  For today's
glory, I turned to Andrew's branchcut formula, assigned a value
of sqrt(2) to both p1 and p2, and let the fractals fall where
they may.

In a valley area of a midget in the main fractal I found the
smaller midget that appears in today's scene.  This midget is
one of the more mis-shapen ones I have yet come upon.  I named
the picture "Ejecting Minibrot" when the midget reminded me of
one of those blobs of plasma sometimes ejected from the dark
cosmic clouds that are giving birth to stars.

The most interesting aspect of the image however is not the
midget but the surrounding features, which are of a totally
different nature in the upper and lower parts of the picture.
In the upper half of the image, the features are sharply angled
geometric shapes; in the lower half, the features have a far
more decorative feathery appearance.

The parameter file takes about one hour on an obsolescent P200.
The image file, which has been posted, takes about one minute to
download from:

          <alt.binaries.pictures.fractals>

or from:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

The fractal weather (now that we realize the weather behaves in
a fractal manner, weather is on-topic) was cloudy and raw all
day, with light rain in the evening and a temperature of 53F
(11.5C).  It was a bit too chilly for the fractal cats, who
didn't even ask to go outdoors.

For now, it's time to shut down the fractal shoppe and settle
into my favorite chair to watch some junky old sci-fi movie.
Until next time, take care, and keep asking questions.

Hi all,
If you haven't seen this series of articles, they are worth looking up.This
one starts with the lyapunov exponent and has lots of links

The recently posted link to a Lyapunov article has reminded me of something
I have wanted to request for a while now:  the actual Fractint formula for
the Lyapunov type.  I've searched Orgform and not found it (there was
something called lyapunov, but it wasn't the same as far as I could tell).
I'd like to tinker with the formula.  Could someone post this to the

Well, in my case Fractint is run mostly from
my MS-DOS 6.22 boot partition, so I'm using
the DOS editor (QBASIC in disguise).

I've just tried and wrote a new SSTOOLS.INI
with Notepad under Win98, but got the same results.
Maybe this has to do with the localized
versions of the OS's (German in my case).

Anyhow, as long as it works by another way,
I've no complaints :)


Greetings,
Gerald

It looks like you may need to update the library listings. Try:

[root/root]# ldd xfractint

You may find that you are missing a library, or missing a link to it.
ldconfig should fix the problem. This program evaluates the file
/etc/ld.so.conf. You may want to check that file to make certain that it
has all of the entries it needs. I'm running Redhat 6.0, but I've gotten
the same sort of error message on other programs. check out the man
pages for ldd, and ldconfig on your system for infomormation.

Thanks for your suggestions... Indeed 'libncurses.so.5' is
missing. It isn't on the red cd with the rest of the rpm's,
and it's nowhere installed on my system. Do you have any
idea where I could look for this lib, and if I find it
out there somewhere, where I should install it? As you can
see, I'm only a relative newbe with linux.
thanks again,

Subject: (fractint) FOTD, 24-04-00  (A Midget Brainiac [4])

FOTD -- April 24, 2000  (Rating 4)

Fractal visionaries and enthusiasts:

For today's fractal I returned to yesterday's formula, refining
it a bit by entering sqrt(2) to an accuracy of 12 decimal places
- -- not that this made much difference in the resulting fractal.

When calculated normally, this fractal has no negative tail, but
when more remote slices of the infinite fractal are calculated,
a tail is indeed seen to exist, and quite a long tail at that.
It's actually more of a filament than a tail, extending north
instead of west, and crowned by a prominent minibrot.

Since I enjoy examining tails (fractal tails that is) I zoomed
in on the mis-shapen midget on the tail of today's fractal,
paying particular attention to the tail-filament where it enters
the east valley area of the midget.  In the classic Mandelbrot
set, sub-midgets on filaments in the east valley area of larger
midgets are surrounded by a brain-like pattern, with converging
elements splitting in a 2,4,8,16... sequence.  In the Z^1.414
Mandeloid, the elements should split in a 1.414,2,2.828,4...
sequence.  And as today's picture shows, they do indeed.

At first I hoped that every other split would result in a whole-
number unbroken pattern, but this is not so.  The element
fragments at the four level for example may add up to an even
four, but they are so discontinuous that it is impossible to
count them.  Regardless, the sub-midgets in the east valley area
of larger midgets of low-order Mandeloids make interesting
pictures, as today's FOTD shows.

While exploring the parent fractal, I also noticed that the
midgets lie far deeper than would be expected when compared to
the classic Mandelbrot set.  In the classic set, a midget lies
about twice as deep as the point where it first becomes
apparent.  Thus, if the signs of a midget appear at a depth of
10^5, the midget itself will lie at a depth of 10^10.  In the
Z^1.414 fractal however, the midgets lie at a depth three times
the depth where their location becomes apparent.  If the signs
of a midget appear at 10^5, the midget will lie at 10^15.  This
makes midget hunting far more challenging in this fractal.

But even though the effort of finding them is more difficult,
the lower order midgets are worth the effort, since they come in
any shape imaginable.

I named today's picture "A Midget Brainiac" because the scene
was found in a part of the fractal world where midgets resemble
super brains.  At over seven minutes, the parameter file isn't
unbearably slow.  Still, the download, which can be found on
Usenet at:

          <alt.binaries.pictures.fractals>

and on the web at:

          <http://home.att.net/~Paul.N.Lee/FotD/FotD.html>

is the faster choice.

The USA weather might not be the most important topic for those
living in Australia, but here in fractal-land it was cloudy and
56F (13C) -- too chilly for the fractal cats, but pretty good
for philosophy.

That philosophy has been festering all day, though it's not yet
quite ready to come to a head.  It may erupt tomorrow however,
so check then on the Philofractal list to see what trouble I
might get myself into.  And until then, take care, and think
deep thoughts.
