I have been away for 5 days (probably not a bad thing- cameback to about 234
fractal- related  messages!)  I was reading
the book "Chaos Under Control    The Art and Science of
Complexity"  by David Peak and Michael Frame,  (W.H. Freeman
Co.  1994)  and there was a section on strange attractors. The book is
very interesting, aimed at a college-level non-mathematicianaudience.  The
section on fractal dimension was also reallyinteresting,  made me start seeing
everything folding all around
and understanding why people are seeing fractal forms in
nature- beyond my previous "hey! that looks like a fern."

Tim,

  I tried out your new Simplegif on several logged cases of mine where
Simplegif failed on 3200x2400 resolution images.  So far, no problems! It=

working beautifully!  This is one bug I'm glad to see squashed. If
incorporated into Fractint, it will probably clear up the less numerous
(but not too infrequent) cases where it still crops up in 1600x1200 image=

 (I've even had it occur in 192x144 thumbnails.)  I'm sure that Jon Norin=

I have already modified the developer version of Fractint. I would
like to hear most test results though. I have only heard from you and
Sylvie. Kerry wrote a note also, but I don't think he tested the new
code.

If the new encoder tests out, it will raise early release
possibilities. We might release a version 19.6 plus encoder or (with
more work) we could release the current developer version. The
problem with the latter approach is it is a big effort to release,
and it will slow efforts on the big changes such as true color.

Folks, I am more interested at this point in knowing that the new
simplgif works than knowing cases where the old one failed.
(Although of course it is good to know the new one works on images
that broke the old program!) The new code is at:

ftp://ftp.phoenix.net/pub/USERS/twegner/simplgif.zip

You can test it using existing images via:

simplgif existing.gif test.gif

The file test.gif should be a valid GIF87a file. (It won't have
fractal data unfortunately.) The file existing.gif does not have to
be (but can be) a multiple image GIF. Simplgif writes a large
temporary file in the current directory.

Thanks.

Tim

Yes, symmetry is likely the problem. It is up to the user to make
sure that the formula mathematically has the symmetry specified.
Fractint assumes in it's algorithms that the mathematical formula has
the symmetry thatbthe user askes for. There are times when Fractint
does the wrong thing if the formula is not really symmetrical. An
example is panning the screen. Fractint *could* be made to do
ka;eidoscope effects with symmetry, but this wasn't the idea befind
the symmetry options. The program uses symmetry purely as an
optimization.

For safety, symmetry should be turned off when using the
divide-and-conquor process.

I believe that was at Fractal-Art, and they collected _ALL_ links

Now if you want a list of fractal related URL's........  :-}   which

Hi Fractintiers,

A local close out book store just went belly up. So I got an
extra copy which I'll pass on to who ever wants one on this
list. I let a publisher I know handle the details of selling and
shipping. The price is $20 plus tax and shipping.  The book
includes CD, floppy and 3D glasses.  I also got a copy ($15)
which had these extras ripped off. Email me directly if you
are interested.

Unusual apology for the SPAM, I'll make up for it with a
detailed post about orbits, Julia sets and the mysterious

I've successfully entered prm and frm files using Wizzle's Champagnezz

reset=1950, others have reset=1821 others have no reset variable at

The 1821 and 1950 refer to Fractint versions 18.21 and 19.5,
respectively.  An older version of Fractint will have problems with a par
that uses capabilities only found in newer ones.

If you do not have the latest version, 19.6, it is available at:

http://spanky.triumf.ca/www/fractint/fractint.html

Spanky has a great deal of Fractint material in it, a starting index for
which is at:

 http://spanky.triumf.ca/

Good luck.

Sorry.  I would send you tim's_fract, but I repartitioned my HD
between then and now to try out Linux and XFractint, and didn't
make a backup first.  (Smack me here).

As a result, all old files disappeared, including Tim's.  Bottom

Hi.  It sounded like "Name the Artist" at Jack and Margaret
Valero's web site was about to go away so I went back to
have a look.  It's very interesting, quite a good choice of
different fractals from different people and well chosen.  My
favorite was actually  "Coral Reef" and I did not realize it was
by Sylvie Gallet- definitely art, but it was not at all geometric and
it was not in metallic colors.  I guess these are superficial qualities
and if you look at it more closely you can tell.  I think they were
overly humble in being a little apologetic about including their own
fractals in there.  I was am curious about the fractal "Faerie Stone"
how it was made and how the palette is so "liquidey."

I'm not offended...

But isn't this a well-known fact? I thought it "obvious" that self-similar
and other fractal-dimensional scaling phenomena in nature are only such
over a finite range of scales. There is after all a quantum limit to how
small a thing can be. The universe, too, is thought to be very large but
finite.

The fractal structure of tree bark starts at the cellscaleand ends at the
bark thickness scale, and so forth.

You want to read a short story by Christopher Cherniak titled "The Riddle
of the Univese and Its Solution". It appears in Hofstadter and Dennet's
_The Mind's I_. In it a certain piece of information is discovered which
brings on something that becomes known as "Riddle Coma" - the first victim
dies of starvation.

"The outbreak of a Riddle coma epidemic in conenction with a
computer-assitsted theorem-proving project could be explained; if someone
discovered the Riddle in his head, he should lapse into coma before he
could communicate it to anyone. The question arose of whether the Riddle
had in fact been discovered earlier by hand and then immediately lost. ...
At present, at least ten suspect cases have been discovered, the earliest
almost 100 years ago."

More complicated case: The server delegates portions of its job to other
servers as if it were itself a client. An example would be a server
receiving a request to calculate an 800x600 image and then breaking it into
three 800x200 images - it could do one and pass the other two on to other
servers. When those servers send back their work it would stitch the
results together a la Simplgif and squirt the whole lot back.

But will there be enough servers to go round?

I'm not offended either....but I think those items Paul thinks are "obvious"
are far from being so to us ordinary souls.....

I do enjoy watching all the math and programming chat...and appreciate the
opportunity to insert questions and comments.  Speaking of....is there a way
for me to force every view of a par to be with "g" rather than what the
author of the par has in mind??? I like to "speed read" thru pars..since I
often can't remember which ones i've seen and which are new.  Having to
reset the other options is a pain. ??????????

The truth is that you don't need any mathematical knowledge to fool
with formulas, just enough knowledge of the formula language to write
formulas that are syntactically correct. The best way to do this is
modify existing formulas.

When I give demonstrations to high school math classes, I have
fun writing bizarre formulas bristling with important-sounding
transcendental functions like sinh(z) or exp(z). You can just about
always get an interesting fractal in this way. I don't know about
molecular structure, but you can certainly model fractint formulas
after famous equations. I'm not sure the results are any better than
just typing in some hocus pocus though <g!>

Here's one I just wrote down with zero mathematical insight. I
challenge the list to come up with some nice PARs using this.

Tim's_fract { ; Example of a more or less random formula
  z = Pixel:
   ; I have no clue what the point of this formula is
   ; it came straight from my subconscious <g!>
  z = (sinh(z*z + log(z)))/(z*z + 2)
  |z| <= 16
  }

Let me also say that while non-mathematical artists can show
brilliant creativity with formulas, understanding math can add
another dimension to fractal art. Sylvie Gallet, for one, is a master
at applying her knowledge of mathematics to the art of building
formulas that create fascinating fractals.

On behalf of all bgOutlook (and probably bgExchange and Outlook Express)

a space after them, and are not split over two lines :->

Like this: http://altavista.digital.com - easy really.

If you want you could do <URL: http://altavista.digital.com > , as long as

That's just it... the compuserve software isn't thinking at all; it
just puts printed-quotable on every message it sends.  At least, that
is what the compuserve technical support people seem to be saying.

Yes, other people have been sending a few messages that are this way.
However, although I didn't do an exhaustive search of every message
ever posted to fractint, I just looked over the ones I'd gotten
recently.  Of those, the ones with content-transfer-encoding of
printed-quotable were from:

    Lee Skinner <[e-mail]>
    Les St Clair <[e-mail]>
    Sylvie Gallet <[e-mail]>
    [e-mail] (Guy Marson)
    "Steve Jenks" <[e-mail]>

With the two non-compuserve addresses accounting for only 4 messages
out of 42.  Of those 4 messages, one originates from a place on the
globe where iso-8859 is the natural encoding (i.e. europe) and the
others are in printed-quotable because of the way Steve Jenks appears
to have configured his email program.  (Microsoft Outlook Express)

There is one strange one however.  Clamcake forwarded one of my

Excuse me, but you are incorrect.

Have you ever used, or do you use, the "QuickRes" utility that I
mentioned???

I can go from the following modes back and forth in only about a second
with no reboot what-so-ever:

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1280 x 1024  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)
   1024 x  768  @  HiColor (16-bit)
   1280 x 1024  @  HiColor (16-bit)

    640 x  480  @  TrueColor (32-bit)

Besides, "Bagpuss" only mentioned changing resolutions (the number of
pixels in the image horizontally and vertically).  Nothing was mentioned
about the amount of colors available (even though it may be done without
reboot).

Resolution is the amount of definition and clarity in an image.  The dot
pitch of a CRT display monitor affects resolution.  However, resolution
is usually measured in terms of the number of pixels ("picture elements"
or screen "dots") per square inch.  By varying the display device driver
the operating system is using, a user can vary the resolution of the
monitor by changing the number of lines on the screen and thereby
altering the number of pixels.  For example, one could reset a Windows
setup to select a driver that provides an 800 (horizontal) by 600
(vertical) line display.

The upper limit of resolution for most PC monitors is about 72 to 100
pixels per inch. As a comparison, most PC printers offer 300 to 600 dpi
(dots per inch) resolution.

Yes, and it required me to reboot if I changed the pixel depth.

Must be something unique with your system setup.  I have been using is
for around two years now without problems.  And all of my friends and
work associates that use it have never had any problems either.  In
fact, there are thousands of individuals that use this.

Maybe you should try downloading it again from:

   http://www.microsoft.com/windows/windows95/info/powertoys.htm

And then give it another try.

Subject: Re: (fractint) Client-server Fractint

I'm using P166 Win95 version 4.00.950 B and not the greatest
amount of video RAM. I'm not using QuickRes, but I can
change among these without rebooting

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1152 x  864  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)

But if I want higher resolution I can get

   1280 x 1024  @  16 color
Going to this one I must reboot.

I think there is a Win 95 version dependency here.  An older
version on a P200 with bigger monitor and more RAM had
to boot as I recall. I'll check it again later.

I believe that the reboot requirement depends on your video card.
So as I said before, even though you have the MS "power toy", you
still may be required to reboot when changing video parameters.

This could be possible, or it might have to do with the OS release

Well, not quite what you said before.  But, at least you have revised
your original "will still have to reboot" to "may be required to
reboot".

Question: Is the equation z=cos(z)/z+pixel correct? If so then c=z=pixel
is not needed & should be rewritten as z=pixel. If, on the other hand,
c=z=pixel is correct, why is there no "c" in the equation? In other
words, is "c" being used or not?

Taking Bill Rossi's recommendation of this past Monday, how about...
z=fn1(z*z)/z+c or z=fn1(z*z)+c/z+pixel or fn1(z*z)+c/z or
fn1(z*z)/z+c+pixel or, or, or, etc. etc. etc.

Just putting in my two pfennigs.

You can solve this potential problem by enclosing the URL in <URL: >, as in
<URL: http://www.yahoo.com/>.  The <URL: > enclosure has been proposed as a
way to embed URLs safely within other text files and have them be easily
recognized and extracted by programs.

No, please don't do this.  I'm using bgOutlook and it includes the final
">" as part of the URL :-(

Maybe put a space before the end of the URL and the ">".

Rich,

 - This is only true if you don't change the depth of the pixels.  So if
 - you switch from 1280x1024 256 colors to 1024x768 16-bit color, you
 - will still have to reboot.

Not true.  You can switch color depths, too.  The problem is, most
graphics
software only checks the color depth when it is first started, so if you
change color depths, the software isn't smart enough to check and adapt.
Closing and re-opening such apps generally is enough to get them to work,
and closing all graphics apps and re-opening them is a far cry from a full
reboot.

I have personally used QuickRes on many different graphics cards, and it
never required a reboot on any of them.  However, I *have* used the
"screen
managers" that ship with most brand-name graphics cards; these managers
also provide a resolution-switching option, but they generally *do*
require
a reboot.  I typically disable video card screen managers now, and just
use
QuickRes. :)

Bagpuss,

 - hmm, I DO care if the render time goes up...
 - Win95 has a horiffic processor overhead, and while this is
 - fine on a fast machine (most programs dont use very much
 - processing power) for processor intensive work (like fractal
 - and 3d rendering) DOS is better by far - up to 2.5 times
 - faster on my machine.

Then your machine is configured incorrectly.  Properly set up, FractInt
running in a DOS box under Windows 95 is only 2% slower.  This has been
covered before on this list.

BTW, I have about 10MB of archive of this list from which pars and frms

Question again (I asked this a week ago). What do all you all
think would be the right way to do this? One big frm and one
big par for each of 1996, 1997. Then small ones this year?
What should be included? Enough of the header and test to

of cross referencing between them. frm will need a reference
to the names of the sample pars. Anything else?

10M!  I thought I had all the messages, but I've got less than 7M of
material.  (Then again, I didn't get that 2.5M file somebody posted to the

A big PAR for previous years should be fine.  If the creators did not
include their name in the PAR comments, edit the PAR to include the name.
The date of posting would also be nice, but not critical.

All FRMs should be in a separate file, organized similarly: author's name
included, possibly date of posting.

Wasn't someone also collecting URLs posted to this list?  Or was that the
Fractal-Art list instead?

Thanks to Jay for purposely piling up Paul's proxy postings.  :-)

What I did, to make his file a legal par, was to wrap comment { and }
around the text part of the pars.  Perhaps this could be incorporated into
the grand par/frm extraction project.

Just posted in alt.binaries.pictures.fractals is a .jpg image of a fractal
in a very nice astronomical setting. The image itself is well worth
seeing,
IMO, titled eggsplosion, Karl Boehnker.

If Fractint is able to generate something something similar, would someone
kindly post how? I have seen two similar (only in a sense, one was a
couple
of spirals in an astronomical setting) pieces before...(BTW, I have also
emailed Mr. Boehnker concerning this...)

After hitting "a", the _only_ thing I have ever been able to generate is a
star field and have never been able to do anything with it. Including when
starting off with a fractal before hitting "a"...

Beginning after the recent contest, I have been collecting most pars and
frms that
have come through to my mailbox.  My save format is  something like this:

; Date
; From

; or Comment { ... } if there is a comment  or part of a comment I want to
save

formulas or image parameters

But I change as I go - lately, I've just been making a  single comment out
of date,
from, and any narrative I want to save.

Up to December 31, 1997, I saved them in Dec97.par and Dec97.frm.  All the
pars
are  cleaned up and all draw.  For many of the images, I've modified the
comment
lines in the parameter sets by adding the time it takes to draw on my
equipment.
If there were formulas without pars to call them, I have only spotchecked.
 Some of
the formulas, like the vector and dmj-pub formulas, I've saved in their own
frm
files, again with spotchecking on how they run.

There's an exception to haveing all the par/frm sets!  Somewhere along the
line, I
lost track of the formula, xmasseahorse.  Maybe somebody could repost that
one to
me at my personal mailbox.

Now, I'm working on Jan98.par and Jan98.frm.

I have not taken the time to cross reference the example pars to the
formulas
because the formula names appear in the pars and can be searched out with
PFE32 or
by visual scanning in an editor.  This should not be much of a problem if I
stay
with the month-sized files.

Dec97.par is about 58K and Dec97.frm is about 20K in size.

I don't have much experience in posting except as attachments, which I
understand
some of you have difficulty with.  If anyone wants one or both of the
above
collections, the vector frms or the djm-pub frms, let me know, tell me how
you want
them posted to you, and I'll give it a try.  If the number of people
wanting them
is small, it will probably be best for me to send such postings to your
personal
mailboxes.

I'm not committing to anything for the future!  I have to travel in my
work, and
may even eventually decide to withdraw from this list because of the volume
of
traffic -- 60 to 80 messages in one 24-hour period is a bit much!  Sure
have been
learning a lot, though and getting many good images and formulas.  So, I'll
stick
with it as long as I can.
