Subject: (fractint) FOTD, 15-04-00 (Midget Madness [4]) (c)

FOTD -- April 15, 2000  (Rating 4)

Fractal visionaries and enthusiasts:

Today's picture shows what happens when a midget goes totally
mad.  To begin, no midgets should exist in the Mandeloid of
order 1.15.  This holds true however only in the default section
of the entire spiral figure.  As we examine ever farther out the
spiral, the little default jelly-bean blossoms into figures of
the most extraordinary shape.  And it is in these far-out slices
that the unexpected midgets lurk.

Most of today's picture consists of branch cuts radiating from
the midget, which actually rather resembles a Julia midget.  In
fact, in some areas of the parent fractal the cuts become so
numerous that they determine the actual image more than the
iteration bands.  Since discontinuities are not all that
interesting, I could rate the image no higher than a 4.

I named the picture "Midget Madness" when I was struck by the
disorganization of the scene.  And yes, smaller midgets do exist
in some of the fragments scattered around the area.  I might
show one of these smaller midgets tomorrow, but more likely I'll
return to the MandelbrotMix4 formula for some more good old
quadratic midgets.

At 8 minutes, the parameter file of today's image is a bit slow.
Things can be speeded up quite a bit by downloading the JPEG'd
image file from:

          <alt.binaries.pictures.fractals>

or from:

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

And now, on to what you've all been waiting for -- the fractal
weather report.  Mostly cloudy and 60F (15.5C) describes the day
fairly accurately.  The temperature was a bit chilly for the
fractal cats, but they did manage to have a 15-minute romp on
the porch.

As I feared it might, the philosophy went nowhere today, so I'll
try again tomorrow.  Until then, take care, and take it easy.

Subject: Re: (fractint) fractals for art competitions

Karl,

 - 1.    Can somebody tell me some art competitions on the net
 -       where I can send fractals (as gif files or otherwise) and
 -       where I do not have to disclose the formula
 -       and/or give away my copyright?

Well, there's always the "big" fractal contest, held in late summer/early
fall. The web site for this year's contest will be www.contest2k.com, and I
expect more details of the contest will be posted there within six weeks.

 - 2.   Does any of you guys do exhibitions with framed art work?

There are several fractal artists who do exhibitions, yes. I dare not name
names because I'm sure I'll leave someone out who'll be disappointed that I
forgot. (Working a few sixty-hour weeks has played havoc with my memory.
I'll be OK after some time off, though.)

 - I just had two exhibitions with 100 framed fractals with lots of
 - good feedback and quite good sales.

Wow, that's great! I always like to hear of people selling fractal artwork.

Subject: (fractint) FOTD, 16-04-00 (Square-Root of Two [5]) (c)

FOTD -- April 16, 2000  (Rating 5)

Fractal enthusiasts and visionaries:

With today's FOTD we come to the end of my current obsession
with the BranchCut formula and the weird images it draws.
Tomorrow we'll return to my obsession with the MandelbrotMix4
formula and the weird midgets it draws.

I named today's picture "Square-Root of Two" because the formula
behind the image is Z^(sqrt(2))+C.  The parent of today's midget
is a distorted Mandeloid with a prominent negative tail trailing
off in a northerly direction, and a prominent triangular bud set
off by a well-defined Seahorse-type Valley.  Today's scene lies
in the west branch of this valley.

Once again, the image is composed of many discontinuities
radiating from the tiny central, almost-formless midget, though
in today's picture the fragmented features in the discontinu-
ities are far better defined.  The parameter file takes over 6
minutes, making the download the better choice.  That download
may be found at:

          <alt.binaries.pictures.fractals>

and at:

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

The weather today was boring -- cloudy with occasional light
rain -- totally unworthy of being mentioned in a FOTD
discussion.  And I have no idea why I continue mentioning it.
The temperature of 60F (15.5C) was unworthy of a day in April.
The fractal cats, being noble creatures, refused to go out into
the unworthy conditions, spending the day lying on their backs
on the carpet with all eight feet in the air.

Once again today I failed to philosophize, but tomorrow will be
another day, (it always is), and I'll have another chance to
show my philosophical insight, (if I have any).  So check in
then.  If you find no philosophy, you'll at least find a nice
one-layer fractal.  Until then, take care, and how can there be
a picture of a fractal that isn't there?

Subject: (fractint) FOTD, 17-04-00 (Stormy Minibrot [8]) (c)

FOTD -- April 17, 2000  (Rating 8)

Fractal visionaries and enthusiasts:

With today's lurid scene, we return to the MandelbrotMix4
formula and the endless variety of midgets it creates.  The
mathematical expression that draws today's image is
(Z^1.1)-(Z^(-1.11))+C -- another whimsical invention of mine
that does more than one might suspect.

Yes, when I enter parameters into the M-Mix4 formula, I often
turn off my mind (an easy task) and let my fingers strike
whatever number keys they will.  I find this method to be about
as effective and far faster than thinking about possible
parameters before striking the keys.  Today's parameters were
found this way.

I named the picture "Stormy Minibrot" when I noticed that the
dark areas around the edges looked rather like storm clouds,
which are nearby this evening.  A bit of color tweaking and a
trip through a graphic program completed the effect.

I consider the picture to be the best in several weeks -- well
worth the superior rating of 8.  At just under 7 minutes, the
parameter file is a bit on the slow side, making the relief of a
download worth considering.  That download may be found at:

          <alt.binaries.pictures.fractals>

and at:

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

The fractal weather was perfect today.  After a brief morning
shower, it turned sunny and warm for the rest of the day, with
an afternoon temperature of 82F (28C), which brought the cats
out doors.  Tonight we have lightning in the north and an
occasional rumble of thunder, but it's still calm and warm here
at Fractal Central.

Well, I see the lightning has now spread to the west as well.  I
guess that's a sign to shut down the fractal factory and call it
a night.  Until tomorrow, take care, but don't take so much care
that life stops being fun.

Subject: (fractint) FOTD, 18-04-00 (Jaws [5]) (c)

FOTD -- April 18, 2000  (Rating 5)

Fractal visionaries and enthusiasts:

Today's fractal has bite to it.  The red triangular features
remind me of shark's teeth, making the name "Jaws" a natural.
The formula behind the image is -4*(sqrt(Z))-4*(1/sqrt(Z))+1/C
- -- another of those surprisingly simple expressions I so enjoy
investigating.

Actually, I had one of my better fractal days today, finding
several images worthy of the lofty status of FOTD.  I also had
some success combining elements of the Branch-cut formula with
the M-Mix4 formula, but the combination needs further work
before it becomes usable.  Fractint also needs about three more
variable parameter entries for type=formula, but that's another
problem.

The parameter file of today's image runs in under 5 minutes.  If
that is still too slow, the image has been posted to:

          <alt.binaries.pictures.fractals>

and to:

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

from where it may be downloaded with a minimum of effort.

The weather was cloudy, cool, dreary and rainy today.  The
wetness and temperature in the mid 40's (around 7C) kept the
cats sung inside.

Since all my spare time was devoted to fractal work, I have no
philosophical wisdom to impart at this time.  I'll try again
tomorrow.  Until then, take care, and be courageous when your
fractal disappoints.

Subject: (fractint) Branch Cuts (what else?!?!)

A big thankyou to all those who helped me with the multivalued-log formula.
And thanks Jim for a few rather nice FotDs with it. I would be very
interested to see it combined with your Max4 formula (I really haven't got a
clue how that thing works, but it's very cool) I suspected that you might
find interesting things by moving the function domain...

...But the *real* reason for my wanting to create this formula was for
amination... I'd like to animate the branch cuts. If I come up with anything
good I'll post it to my web site (if I can get it here on disk!)

I'm also going to look at the multivalue properies of the inverse trig and
hyperbolic functions... Thankyou Morgan for pointing that out (I should have
realised myself, but I'm thick)

PS. Everyone says that FractInt should have more formula parameters; it's
perhaps the most requested feature aside from true colour... And yet it
doesn't happen. Is this just lack of time or is there some fundemental
barrier here?

Version 0.3a is on the server. Some text is added or modified.

I have made changes in the layout because I have discovered yesterday that
Netscape and IE don't handle tables in the same way. If you use Netscape you
will see the change if you compare with version 0.3 (I hope that the
corrupted default page which was on the server yesterday for several hours
is not hidden in some cache). Some changes also in the style sheet to
override some problem with Netscape (however a little problem remains in the
legend of one figure).
If you experience difficulties you can avoid the default page by going
directly to contents.html.

I've already dickered a little with that idea myself - nothing pretty: just
somethign to get an intuitive idea of what's going on. Changing the
argument is equivalent to a rotation of the cut about the origin; going
from 0 to 2pi sees the cut sweeping around, with the fractal winding up (!)
upside down from where it started. Another full rotation gets it back to
where it started. Needless to say, of course, that we're talking fractals
here, so the visible behaviour is a bit more complicated than this.

Only a victim of coincidence - I just happened to be mucking around with
them and their Reimann sheets for another reason at the time. This thread
has helped me with a few more ideas in return.

There is indeed a fundamental barrier. No matter how many knobs and buttons
are added to Fractint, there'll always be something else that someone wants
to twiddle. And the more knobs and buttons there are, the more ideas for
twiddly bits there seems to be!

Actually we are more than happy to respond to specific requests
for new features. We do have limited time, but if something makes
sense to us, and the proposal is well thought out, and it looks
feasible, we'll do it, sometimes suprisingly quickly.

I haven't been reading the messages closely. We were discussing
mag and arg parameters, and also atan2. I didn't get a clear
consensus from that discussion. If someone would care to state a
proposal, or upload it to the wishlist, or both we could have a look.

Subject: (fractint) FOTD, 19-04-00 (Four of Clubs [6]) (c)

FOTD -- April 19, 2000  (Rating 6)

Fractal visionaries and enthusiasts:

When I saw today's picture I immediately  noticed the four black
club-like appendages overlaid by almost painfully brilliant red.
I immediately named the picture "Four of Clubs".  The formula
behind this scene is once again Andrew's MandelbrotBC, analyzing
the remote parts of the parent Z^2.003+C figure.

This parent image appears as a normal Mandelbrot set rotated 135
degrees CW.  The discontinuity at first escapes notice, but it
is there, coming in from the right and intersecting the period-5
bud that lies on the SE shore of the main bay.  I examined the
area of the intersection to find today's image.

Once again I found many discontinuities in the area, and also
some rather interesting midgets, one of which I captured and
saved for posterity as today's FOTD.  The value of 800 assigned
p2 is most likely excessive.  It exists because I found the
image with the evolver set to a range of + or - 1000.  In all
likelihood, a similar image exists far closer to the default log
slice.

The 20-minute parameter file is too slow for casual fractaling.
I strongly recommend a download of the JPEG image from:

          <alt.binaries.pictures.fractals>

or from:

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

For those who actually care about such things, the fractal
weather today was continued cool and rainy, with a temperature
of 44F (6.5C) that kept the fractal cats safely indoors.

The philosophy suffered today as I continued trying to combine
the Branch-cut and MandelbrotMix4 formulas without sacrificing
the flexibility of either.  It might not be possible without
additional parameter entries for type=formula, but I'll keep
at it.  Who knows, I might even find a way to do it.

But for now it's time to shut down the fractal machinery and
shutter the fractal shoppe for a day or so.  Until then, take
care, and beware of get-rich-quick multi-level fractal schemes.

Hi, all!
I┤m happy to tell you that I┤m having a little (5 images) exhibition at my

changin the resolution. Can anybody help me out? I have an ancient samtron

It may be that the disk/ram "video" mode is rendering your image in
one-pass mode, because this would cause the least wear and tear on a hard
disk. (I don't know how all those numbers work, either, but would like to
'cos I find this a drawback as well.)

One suggestion for a workaround is that you use Fractint's ability to
render an image in chunks and then reassemble them. (2000x1500 just fits
within the limits you give). Hitting F1 from the Save Parameters screen and
scrolling down will describe how to save an image as multiple parameter
entries.

Beware that the centre lines of the reassembled image will be _two_ pixels
wide instead of one. That's because these are the boundaries of the chunks.
Fortunately, the lines would have been there anyway if the whole 4000x3000
image had been rendered in one go, just thinner. At 300dpi, though, I don't
think many people would notice if you touched it up slightly and deleted
the excess by hand prior to printing.

If the video mode goes above 2048 in either the X or Y direction, one-pass
mode is forced.  This is due to a buffer size problem with the
solid-guessing logic.  I'll have to check if tesseral and boundary trace
have a similar problem.

Yes, tesseral has the same buffer size problem that solid-guessing has.  The
boundary trace method doesn't, however.  So we should be able to make it
work with a resolution greater than 2048.

BTW, the buffer size problem is not insurmountable.  But, it will end up
going away when we port to a 32-bit environment.
