In order to understand this, you will have to look at examples in fractint. At one time I was very
familiar with this, but I haven't looked at it in a few years, which is why this isn't the crispest
answer :-).

Look in fractalb.c for some examples. Some of the functions have "bf" in the name. Those are
the ones you want. The functions with "bn" in the name are fixed point and are much more
awkward to use. This may not be the answer you want to hear - but this is how it works. You
have to completely port your algorithm to the arbitrary precision API and code it separately, and
provide a mechanism for changing back and forth. There is a flag that detrmines whether
arbitrary precision is being used or not.

This is all pretty vague, but it is definitely doable if the algorithm  you are coding up in testpt.c
isn't too You can find some code that does the mandelbrot. You have you allocate memory on a
stack by hand.

Unfortunately not. It is probably feasible in Xfractint, but not in the DOS version.

Subject: (fractint) FOTD  17-10-01  (Humanoid Alien [4])

FOTD -- October 17, 2001 (Rating 4)

Fractal visionaries and enthusiasts:

What's more interesting than a red alien face leering out from a
drab green background?  An uncountable number of things.  But
this afternoon, while exploring more odd angles of the Julibrot,
I found a red alien face, which was leering out from a drab
green background.  Not surprisingly, I named the image "Humanoid
Alien".  At the same time, I rated it at a 4, which is a little
below my usual moderate standard.  Actually, I consider looking
for funny faces in fractals to be a bit silly.

The alien face is humanoid of course, with slit-like eyes, a
bulbous nose and a gaping mouth.  It would need to be humanoid
or else we would not recognize it as a face.  This need to
preserve a recognizable bit of humanity in our invented alien
life forms is the reason that so many fictional aliens resemble
human bodies with the proportions changed.

If their physical appearance is totally unlike ours, then our
human-invented aliens must at least react logically and
emotionally somewhat like human beings, or else we could not
connect with them at all.  An immobile puddle of living slime
without thought or emotion might exist somewhere out there, but
the events of its life would make a very un-interesting story.

Today's image is a new angled view of the prominent valley of
the period-4 bud on the northeast shore of the main bay of the
Mandelbrot set.  What's on the screen is all there is to this
particular slice of the Julibrot.

Perhaps the best feature of today's alien image is its lightning
speed.  The parameter file renders in only 25 seconds -- faster
than one can get connected to many ISP's.  But for those who
would rather take the trip to the W.W.Web, the pre-rendered GIF
image is (or soon will be) available at:

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

and at:

          <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html>

With lots of sun and a temperature of 70F 21C, the fractal
weather today was quite pleasant though a bit breezy.  It was
pleasant that is until 5:30pm, when a squall of rain struck,
driving the fractal cats to shelter indoors, where they spent
the evening pondering things only cats are aware of.

I'm still pondering philosophical mountains, and turning them
into molehills, but the philofractal list remains in limbo,
wherever limbo is, forcing me to file away the wisdom for
another day.  Sooner or later it will all break loose however,
so until that enlightening moment arrives, wait with bated but
not abated breath.

As for the fractals -- they'll return tomorrow, same time, same
place.  Take care.

Jim,

But then, no matter how interesting something we might view would
be, there will always be an uncountable number of things more
interesting.

Depends on the person.  There are people who spend their time
studying immobile puddles of living slime that have no thought
or emotion. To such a scientist, the life story of his subject
will be an object of fascination.

A feature common to scientists is the ability to find wonder and
interest in things others disdain as dull.

True.  But those interested in immobile slime make up a only
small percentage of the total population.  As the plot of a
novel, the life of an immobile puddle of slime would fail
miserably.  Also, when I re-read what I wrote, I wonder how a
puddle that for dozens of years just sits there unchanged,
immobile and unthinking like an oil spill could be considered
a living entity.

Haha! That's brilliant! In that case, all I need to do to find my perfect

Might be worth a try.  Be a bummer, though, to lose out to a puddle of immobile
slime.  Then again, I'm a wargamer.  We regularly lose women to puddles of
immobile slime.

Subject: (fractint) FOTD  18-10-01  (Chambered Nautili [8])

FOTD -- October 18, 2001 (Rating 8)

Fractal visionaries and enthusiasts:

Today's image reminds me of a poem we studied in school.  I was
in about the 6th grade and I had the task of memorizing and
reciting the poem.  I can still remember the title, something
like "The Chambered Nautilus", and the first line, which is
something like 'Build thee more stately mansions oh my soul,'.
I hadn't thought of that little poem for many years, that is
not until 9pm, when I saw today's image.

There before me curled an infinity of chambered nautili.  I
immediately named the image "Chambered Nautili" and rated it an
exceptional 8.  The iterated formula subtracts 11 parts of
Z^(-11) from one negative part of Z^(-1.1) and adds 1/C.  The
parent fractal resembles an irregular half-moon, with today's
image located on the northern cusp of the moon.

The image, which consists of as much inside as outside, is a
showpiece of the under-used <fmod> option.  Both inside and
outside are colored with this option.  When rendered in the
manner I normally use, the image rates no more than a 4.

The 6-minute render time is bearable but barely so.  Relief is
at hand however on the W.W.Web at:

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

and at:

          <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html>

where, within the hour, the GIF image will be posted.

The fractal weather today was quite Autumn-like, with brisk
winds, blue skies filled with dark scudding clouds, flurries of
falling leaves, and a temperature of 55F 13C.  All this activity
left the Dynamic Duo perplexed.  They decided to spend most of
the day in the window, becoming huffed up whenever another cat
came into sight, and wishing conditions were a bit better.

As for me -- I wish the day's work were finished.
Unfortunately, the only way I know to bring about this condition
is to get started.  So it's time to shift from fractal mode to
graphic design mode.  Until next time, take care, and I wonder
why complex numbers make fractals.

I was going to say, like an old oak tree, but that fails the
"unchanged" part of the equation.  How about a giant, dormant
underground fungus?  (I heard once there's one in Alaska that
is the largest living entity on the planet--miles across...)

No... I'm saying that *I* am dull, and thus only a scientist would be
interested in me.

Thanks.

I've never had a girlfriend in my entire life. I'm that unattractive.

it's not groving in Alaska, but in the heart of the US, somewhere in the
Mid West. The mycelium (of Armillaria ostoyae) is not dormant but very
vital. Its frontiers are the Pacific and the Atlantic Oceans. But to arrive
there will take 10000-20000 years, if there is no radical climate
changement. Meanwhile it (and its brothers and sisters  >:)  will eat the
big woods..

here is one page about that fungus, not the best and ultimate but see
yourself..

Still getting "server down or not responding" messages as

When I ping fractalus it replies now. I think that Damien has his server
working but that it is necessary to restore all the services... I hope he
has full backups.

Subject: (fractint) FOTD  19-10-01  (Midget Distortion [6])

FOTD -- October 19, 2001 (Rating 6)

Fractal visionaries and enthusiasts:

Today's strange image is a picture of a tiny midget located at
- -1.7496 on the negative stem of the Mandelbrot set, a point deep
in the East Valley of the largest midget of all -- the one
centered at -1.75.

I named the picture "Midget Distortion" because it is distorted
to the point where it resembles a leering face more than a
Mandelbrot midget.  The distortion is caused by slicing the
midget in a new direction -- one of those orientations that
produces neither Mandelbrot sets nor Julia sets, but something
in between.

Since the Julibrot is four-dimensional, there are more in-
between orientations than can be imagined.  The orientation of
today's slice is totally skew -- 45 degrees from all six of the
mutually perpendicular planes of the Julibrot, and one of six
such totally skew orientations in the Julibrot.

I actually chose a perturbed version of the midget to examine in
this new direction.  I did so because the 'true' version of
Mandelbrot objects stretches to a near impossible degree when
viewed in some of the odd directions.  The degree of this
stretching can be demonstrated by changing the real(p3)
parameter of today's image to zero and re-calculating the image.
The parallel stripes that result are quite uninteresting, though
with enough outzooming and stretching in the vertical direction,
the original true midget can be brought entirely into view.

Today's image gave me a rating problem.  Unable to decide on a
rating of 5, 6, or 7, I finally decided on a compromise of 6,
which is a little above average.  The render time of 2 minutes
from the parameter file is about equal to the time required to
visit Paul's web site at:

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

or Scott's site at:

          <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html>

and download the GIF image from there.

Bright sunny weather prevailed today here at Fractal Central.
The temperature of 59F 15C felt warmer than it actually was, due
to the light winds and warm sunshine.  The fractal cats, who
approved heartily, enjoyed several hours of outdoor activity.
Of course, to the cats, outdoor activity means sitting in the
grass, watching birds and squirrels, or lying on one of the
porch chairs, sleeping.

When I last checked, the philofractal list, among others, was
still down.  With no outlet, the fractal philosophy is still
backing up.  But it's not being lost.  Stay tuned for the
re-activation of the list and the imminent eruption of
controversial wisdom.

The clock over the desk tells that it's time to be getting busy
on non-fractal things.  So until next time, take care, and be at
one with something.
