Now that the fractal is fixed, here is what became of it.  Ever noticed
how many of my fractals seem to blow up on me?  Well, this one
looks like some of the stuff I've been seeing on Deep Space Nine
lately.

I use MS Internet Explorer 3 and its Internet Mail.  Anyone on this list use
these products and know how to set the <reply to> field?  BTW, I found
a parameter setting for the number of characters to allow before line wrap.
I set that to 80.

Subject: (fractint) Re: Image Compression/Decompression

Richard,

    Welcome to the list!  Glad to hear that you caught that
PBS special... I missed it myself.  I think your question
is a fine one for this list... and here's my unprofessional
opinion, especially since I haven't seen the film.  You are
on the right track when you say:

> But I suspect, due to the observed self-similarity
exhibited in fractal images,
> using a "reverse fractal filter" (for lack of a better
name), based on
> fractal mathematics, would result in output which
probably resembles the original,
> rather than an exact recreation of it.

    The parrot's eye produced by the fractal algorithm will
be similar to, but not identical to, the actual parrot's
eye photographed.  The same 'restoration' technique can be
used to recreate any self-similar object when a bare
minimum of information is available; easy examples are
pictures of clouds, wood and stone surfaces - add a little
randomness and your computer can produce pictures which
look like the real thing.

    Unfortunately, these approximations cease to match the
real world if we magnify or change the scale very much.
The approximations tend to look exactly the same no matter
how much you magnify, whereas things in the real world
reveal new features (cells, organelles, molecules, atoms,
etc.) as you magnify... this is linked to the fact that
different forces in our universe act over different
distance scales.  So we couldn't use a fractal algorithm to
improve our data; we could only make our data simulate a
standard, but any new, 'true' information would appear
strictly by chance.

    Ok, that's my brain.  Two more things: 1) The
Mandelbrot set is a fractal that exhibits the phenomenon of
novel geometry at all scales (well/poorly phrased?), and
thus is fun to explore, and 2) keep asking questions, even
this one again, if I butchered my explanation and no-one
else responds.  Others here can provide a much more
technical answer than I can.  Again, welcome, and Happy New
Year!        Jason

From the menu MAIL | OPTIONS , go to the SERVER tab and make sure the
"Email Address" field has your full address:  [e-mail]

Then hit the "Advanced Settings..." button from that same tab, where you
will then see a "Reply To:" field which should contain the following:

Well, sexism may be defined as an attitude or behavior based on
traditional stereotypes of sexual roles. When you consider the
essential zooming nature of fractal explorations a little thought
must lead to the conclusion that all fractals are derived from
essentially masculine behaviour.
After all... we do it deeper.

Running, ducking and swerving...

Subject: (fractint) DEEPER Program update

All,
    Ok, I've got a zipfile on my web page - the link from
my main page is a little obscure, on purpose... it's below
where I mention that I've moved to Vermont.  Anyone who
wants to download the stuff and mess with it is welcome to,
at their own risk, but the disclaimers make that point
clear (prob'ly scare folks off, actually... hmmm).
    I've got a little more updating to do to the readme.1st
file this morning to describe what the code does...
basically the program chooses a pixel at random, but the
liklihood that a pixel will be chosen depends on its
'color' (iteration value) so that 'deeper' pixels have a
higher chance of being chosen.  The winning pixel 's (x,y)
location is used to center a zoom box on...  but this'll be
in the readme.1st file if you want the whole story.
Basically, the zoom algortihm is random.  I'm working on a
smarter algorithm...
    I've also decided to develop this as a standalone
add-on (like the Filmer program is) because I think I know
how to proceed with that.  Ideas and suggestions still
welcome!
HNY, Jason

                  Care and Feeding of 3D_Balls_Mset

You're going to need those parameters and colors to make your own 3D Ball
images, boys
and girls. So if you try to bake these at home, you may want to load
3dballs.par after you
have located an interesting MSet region using standard formula.  The initial
un-zoomed
MSet shows up mostly black without detail using Paul's formula.  So locate a
midget or
Misiurwicz point, and note the coordinates and magnification. Then load
3dballs, enter your
coordinates and you are set.

3dballs  { ; Copyright (c) Paul W. Carlson, 1997
  type=formula formulafile=3dballs.frm
  formulaname=3D_Balls_Mset passes=t
  params=0.0065/150/8/30
  float=y maxiter=3000 inside=253 outside=summ
  colors=000c40<28>zW0aG0<28>zz00C4<28>0zR0CC<28>0zz00O<27>FFxGGzI0K<28>fO\
  zO08<28>z0fO00<28>z88000<13>000
  }

Now there must be a better way. The above method should be easier: Find region
using
standard formula, load Paul's formula and colors without loosing the
coordinates. How do
we do that?


Here is one I made. It has some very overlapped balls.

Jack was so kind as to answer my question about sexist fractals with

((P.S.  I've been pondering all day....just what IS a sexist fractal??
>(pondering brought on by Beth's earlier comment)

Well, sexism may be defined as an attitude or behavior based on
traditional stereotypes of sexual roles. When you consider the
essential zooming nature of fractal explorations a little thought
must lead to the conclusion that all fractals are derived from
essentially masculine behaviour.
After all... we do it deeper.

Regards - Jack

and when I visit Jason's page I see he does "unmanned
deepzooming"........can that be quadratic equations as 4 play?? (nice
background Jason....but I can't find the exploding hams except here.)

Subject: (fractint) Deeper Program, now Flarium

Thanks for the encouragement, Wizzle.
     When you are using Flarium, under "view" there
is a choice "color parameters" that gives you a screen
"Flarium 24 color controls"  You can specify a number
for R G B that will change the palette.  There is also a
choice for color cycling under view and also in the color
controls.  I don't think you can change the colors by
choosing or importing a palette like you can in Fractint.
    I have been spending endless hours on the "Inkblot-
Kaos" program from Iterations et Flarium.  It is simpler
than Flarium.  It makes incredibly nice images-some of
the Julia sets are luminescent and mandala-like and most
people who don't know about fractals are very impressed.
Quite a few could be book covers.  You don't have the
sense that you are making an image "from scratch" or
using math like you do in Fractint but it's fun and easy.
      I think these programs are from Stephen C. Ferguson
and you are imposing the "stalks" and "bubbles" which
are Paul Carlson's method (tell me if I have this wrong!)
I think it is great that people have made these as freeware,
(like fracint itself and truemand etc.), not that I would mind
paying money for them but it makes me feel like someone
has done something creative that they care about.

Hi Jason,

Not happy with DEEPZOOM I wrote several years ago?
So you wrote DEEPER?  :-)   Well fine!


In your documentation you ask if there is a good way to
control your batch file. Here is a batch file which exits
when you press 'A' for abort.  Copy the following into
NONSTOP.BAT.  Replace 'dir' with whatever programs
you wish to run.

ECHO OFF
:TOP
ECHO Press the 'A' key to stop
dir
TEST4A
IF NOT ERRORLEVEL 255 GOTO TOP

To create TEST4A.COM (from PC Magazine about 10 years
ago) copy the following debug script into the clipboard.

Then Open a DOS Window window (a DOS window
with the tool bar showing). Click the past button and the
text will be blasted into debug and create the COM file.

debug
E 100 B8 00 06 B2 FF CD 21 74 0C 0C 20 3C
E 10C 61 75 06 B0 FF B4 4C CD 21 C3
RCX
16
N TEST4A.COM
W
Q


Now type NONSTOP and the 'dir' command will run repeatedly
until you press A or a.

Jay

Subject: (fractint) New Pars - New Colormaps

Here are a couple of new pars I came up with....they took a rather long
time to generate with my 100mhz pent...but may be useful for the color maps
which I think are particularly elegant (if you can't wait for the images).

elegance           { ; by Angela 1997 using deeps7.map

  }

BESSEL-2 {
      c = z = pixel:
         z = cos(z) / z + pixel,
      |z| <= 100
}

elegance2          { ; by Angela 1997 using deeps6.map
  reset=1950 type=formula formulafile=bofmaps.frm
  formulaname=BOFMaps61-65 center-mag=-0.293255/0.528031/1.103753

  BN<6>wKU<15>K0A<2>O9I
  }

BOFMaps61-65 {;A variation on Newton's method
;Use 0/-0.5 for P1, and Floating Point to create the fractals used for
;maps 61 through 65, on pages 90 and 91, in "The Beauty of Fractals".

z=Pixel:
z2=z*z;
z3=z*z*z;
z4=z*z*z*z;
z=z-((z4-z3*0.5+z2*0.5-z*0.5-0.5)/((z3*4-z2*1.5+z-.5)+P1)),
|(z4-z3*0.5+z2*0.5-z*0.5-0.5)| >= 0.00004
}

I've included the formulas for those that don't have them. Also....I think
elegance2 is a good example of the stripe-y-ness of gifs-sans-anti-aliasing
adding to the quality of the image.....I think this one has a very deco,
painterly quality.  Without the stripes in the background I believe this
would be a rather flat looking composition.  Sooooooooooo....once
again.....a plea to leave us with "the color palette" if Fractint moves on
to true color.

Actually, Jay, DEEPER *is* DEEPZOOM with  an extra
semicolon... ;^)
But really, I'm not sure I've seen DEEPZOOM - can I can I
can I?

And thanks! for the info on aborting a batch file... I'm
sure it'll come in handy!

Wizzle,

They didn't take too long on a P200.  Nice.

I liked the second one better with colors rotated like this:

Jay....

I had a really hard time deciding exactly where to stop rotating the
colors. ...and I agree...that is a wonderful image as well.  I usually end
up with at least 4 color variations that I save when I find a good
image.....had to buy a zip drive to keep all the fractals from overloading
my itty bitty 2.6 gig hard drive. <<sigh>> I remember when 800 megs seemed
like more space than I could ever possibly use.  I just finished loading up
the third (!!!!!) 100 meg zip disk with fractals. My next puter is gonna
have an internal zip drive...I just love it. At $129 it was a great
buy........highly recommended....mine just plugs into the parallel port but
has a nifty interface so I can still print thru that port as well.
