Fellow Fractaliers,
<p>1) After my latest attack of on-list rudeness to Bob Margolis, Administrator
Tim Wegner sent a face-savingly private note re the drawbacks of such "heated"
exchange, its off-topic nature, and simply asked that we "take it outside",
which we did.
<br>Tim then posted an instructive anecdote about his own bittersweet experience
with the great American "justice" system in a similar fact situation.
<p>I promptly received a long and thoughtful communication from Bob containing
not a single mention of my inappropriate on-list comments of the day before.
<p>So the characterizations in Para 2 of "BN Merenoff" (Collin?)'s 12:24am,
1/1/01 post are incorrect as well as unnecessarily <i>ad hominem</i> (and
I speak as an expert in the latter).
<p>2) I applaud Tony Hanmer's efforts to get more attention paid to L-Systems
online. Their increasing applicability as a modeling tool in a broad range
of areas, although largely unforeseen to Prusinkiewicz and Lindenmayer
(<u>The Algorithmic Beauty of Plants</u>, SpringerVerlag, 1990, ISBN 0-387-97297-8,
and other publications) nevertheless make them excellent candidates for
a Competition or (even better?) a List of their own.

Dear Multiple,
The real issue that Bob found fault with was that Mr. Miller had
taken his fractals out of the hobby and put them to a purpose that no
longer inspired mathematical creativity. He felt that, by using his
fractals in a non-mathematical way, Mr. Miller had trivialized the work h=
e
had done in obtaining beauty from the formulas.
What you have to understand is that being able to express yoursel=
f
rationally despite anger is a rare gift; one that Bob doesn't have. He
probably didn't even realize that copyright law wasn't what he was really=
upset about.
Sincerely,
Collin

I thought I had read some stupid posts in this thread before this
one. This one makes all the others look quite intellectual in
comparison.
Good grief.

It sounds like a bug in the video board. Fractint uses standard
VESA mechanisms for detecting when the video refresh happens.
Occasionally a board doesn't have the correct VESA
implementation. I'm sorry I'm vague, Bert Tyler was the expert at
this. I suggest looking at Matrox's web site for BIOS updates.
When these problems were found in the past with ATI, the fix
involved a bios-fixing TSR porogram prtovided by the vendor.

The Phoenix BIOS won't help. It's the *video* bios that might be the
issue.

Two- and three-dimensional renderings? Renderings with something other than
line segments?
Technically, the L-system consists of the axiom and production rules; what
the resulting strings are used for is open slather. L-system generated
music, anyone?

Hey, I never worked with L-systems much and am curious about your results

Would you be so kind and post 2-3 parameter sets of what you think are your
nicest images?
Who else mentioned self-touching fractals? got me interested too...

I've become aware of the limitations of L-systems with only 1 string after
axiom etc; e.g. I can produce many Twindragon variations with only 1 string,
but so far not one Dragon Curve variation.
(Thanks for the compliment, though, Morgan. I experiment a lot but
generally it's shots in the dark and serendipitous discoveries rather than
deep understanding that gets me where I'm going.)

Since Damien initially announced the "Fractal-Art 2000 Contest" on Mon,
26 Jun 2000 at 00:32:49, we have yet to see a conclusion. From the
announcement and discussions up through the actual submissions, things
were the usual slow and late progress, but now it has been over six
months.
Adding new categories might make the next Contest take years to
accomplish.

Subject: (fractint) Fractal-Art 2000 Contest Update
Good evening folks.
It is my duty to inform you that the end of the world has come. At least,
I think it has... because SURELY the end of the world would come before
the contest entries are posted!
Yet the entries are now available for your viewing pleasure.
I need to extend copious thanks to Janet Preslar and Kerry Mitchell, who
have spent many hours with me this weekend getting this gargantuan feat
accomplished.
I apologize to all contest participants for the extreme tardiness of the
contest site's release. I grossly underestimated my available time and
the amount of time it would take simply to post all the images. 453
images and animations are in this year's contest, 170M of data. The delay
had virtually nothing to do with scripting, and everything to do with
time allocation on my part.
Anyway, the entries are up! Try not to all jam the server at once. :)

Certainly by the end of the month. :-)
As soon as I can download the necessary file(s) from Damien. I just saw
the announcement, but I haven't spoken to him about the CD image yet.
I'll be able to get the preorders out within a day or two of downloading
the files. I'll post a message when they are "in the mail".

Subject: (fractint) C-FOTD, 03-01-01 (Parabolic Lace [7])
Classic FOTD -- January 03, 2001 (Rating 7)
Fractal visionaries and enthusiasts:
I'm back! Though with all the copyright blather on the lists,
I probably wasn't even missed. And perhaps it would be more
accurate to say I'm half-back, since I'm still waiting for the
new software CD to arrive in the snail-mail from Mindspring-
Earthlink, so I can once again start sending through my
Mindspring ISP. Until the software does arrive, and I get it up
and running, I will not be able to post the FOTD images to ABPF.
Until then (hopefully only a day or two from now) I will avoid
unusually slow-to-render parameter files. Today's 14-minute
image is borderline, but worth the effort.
I return with a midget from the MandelbrotMix4 formula, a rather
spectacular midget at that. When I noticed the parabolic
strings of bays, I decided to name the image "Parabolas". Then
I noticed the overall lacy effect and considered naming it
"Lace". Unable to decide, I finally named the image "Parabolic
Lace", a name that accurately describes the scene.
The expression -1.1(Z)-0.011(Z^(-100))+(1/C), a whimsical series
of 1's and 0's, lies behind the tan and green scene, which
features a tiny midget at its center. The midget is rotated
about 60 degrees CW from its normal orientation, though the
midget is so small that the rotation is barely noticeable.
Due to computer problems, I am unable to post the GIF image to
Usenet, but as soon as he can get it rendered, it will be
available on Paul Lee's web site at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather has been cold but uneventful since I last
reported. Today for example was partly cloudy with a
temperature of 30F (-1C), which kept the fractal cats indoors
chasing the elusive shafts of sunlight.
I've got a good bit of philosophy backed up and ready to write.
Today was too busy to give the wisdom the attention it demands,
but the after-holiday rush will be gone in a few days, so keep
tuned. Until tomorrow, when I'll return with another wonderful
fractal, take care, and without fractals life would be only half
as enjoyable.

Subject: (fractint) C-FOTD 04-01-01 (Impossible Fractal [6])
Classic FOTD -- January 04, 2001 (Rating 6)
Fractal visionaries and enthusiasts:
Today was one of frustration here at Fractal Central. The
frustration began when I had no success getting the old 1996
Mindspring Windows 3.1 software to work on the new machine,
which runs Win-98. The Earthlink tech support was of minimal
help, informing me that they no longer support that software.
But they did tell me that the current software should have
arrived by this time. This was of no help either, since the CD
has not in fact arrived. They concluded by telling me to
reorder the software if it does not arrive in a few days, an
action I had already considered.
The frustration continued when I found a major bug in the latest
float-only version of Fractint. I have not fully investigated
the bug, but it appears that the formulaname information is not
being properly written to the GIF image files, causing the
program to pick up whatever formulaname info is current in the
environment. I'll have to determine the exact nature of the bug
before making the official report.
The frustration reached a climax when a customer reported that
my service bureau had delivered a faulty negative to them,
causing me to utter a few well-chosen words.
Despite the frustration, I managed to find a fractal. I named
the image "Impossible Fractal" because such an image would
appear to be impossible. The formula that drew the image is a
generalization of John Goering's, SliceJB formula, which makes
use of the new 4th and 5th variable parameter entries.
Since I still am not able to connect to the Mindspring news
server, the GIF image has not been posted to Usenet. But it
will be available at Paul Lee's web site as soon as he can
render it. The web site can be accessed at the URL:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
The fractal weather today was sunny but cold, with a temperature
of 34F (1C), which kept the cats indoors.
And I guess that's it for today. Such frustration is not
conducive to philosophical pondering, so there is no philosophy
today. If things calm down tomorrow however, the philosophy
might appear. The only way to know for sure is to check back
then. Until tomorrow, take care, and what would happen if all
the possible fractals suddenly ceased to exist?

Subject: (fractint) C-FOTD 05-01-01 (Four Flying Wings [6])
Classic FOTD -- January 05, 2001 (Rating 6)
Fractal visionaries and enthusiasts:
Between real work, fighting with the Fractint float-only-version
bug, and trying to gain access to ABPF with the Agent newsreader
through Earthlink, I once again found little time for fun with
fractals, much less for serious philosophizing. Maybe, when I
finally regain access to ABPF, I'll philosophize about the
comedy of errors that kept me from getting connected. It will
seem more like a comedy at that time.
I did find a fractal today that rates a 6, which equals slightly
above average on my entirely subjective scale of fractal worth.
I named the picture "Four Flying Wings" after the four brilliant
wing-shaped yellow areas surrounding the central midget.
The mathematical expression 0.06Z^(-511)+0.6Z^(-2)+(1/C) created
the fractal. The MandelbrotMix4 formula iterated the above
expression to produce the image.
At somewhat under 9 minutes on a P200, the parameter file is
rather slow. To save time, give Paul a chance to render the
image, then go to his web site at:
<http://home.att.net/~Paul.N.Lee/FotD/FotD.html>
to download the image.
If all goes well, I'll resume posting the FOTD images to ABPF
tomorrow, but so far very little has gone well.
The fractal weather today was partly sunny, with a temperature
of 35F (1.5C), which allowed the fractal cats a few minutes
outdoors to romp in the yard.
That's it for now. Until next time, take care, and fractals are
as real as you make them to be.

Subject: (fractint) Major float-only bug alert
I have found a major bug in the most recent float-only version
of Fractint. The bug appears when a type=formula image is saved
as a GIF file. When this is done, the formulaname= data is
either incorrectly written to the GIF file or not written at
all, making it impossible to do further work with the image.
The only workaround I have found is very inconvenient. The
workaround is to save the parameter file of the flawed GIF
image, enter the correct formulaname= data into the parameter
file by hand, redraw the image from the edited parameter file,
and use the redrawn image for further work.

Subject: (fractint) Why wait for a disk?
Mr. Muth, why wait for a disk? Windows 98 includes all the software needed
to connect to a normal ISP -- the dial-up networking thing. Any decent ISP
will have on their Web site the information needed to set it up -- DNS
addresses, name of news, pop, smtp servers, and such. Even my ISP has that
information, and they are not a very good ISP (indeed, all damn morning
their pop and web servers have been incorrectly ignoring my connections
instead of responding to them). If earthlink (or was it mindspring? I
forget) forces you to use special software to connect or to use some
functionality (e.g. news), I respectfully suggest you find yourself another
ISP, one that works in a more standard way. As for the rationale behind
preferring a normal ISP to a weird one that does things in non-standard
ways, your own experiences over the last few days provide all the evidence
needed to support it.
(This, by the way, is also one of the arguments against using CI$ or AOL --
the terrible latency between their internal networks and the net at large,
which plays hell with real-time gaming such as RTS games or Quake, are
another, and economics the third...)
