Subject: (fractint) Linux version of Fractint?

 I was a Fractint fanatic when I was running DOS, many moons ago.  Since leaving
DOS behind and moving to Linux a number of years ago, I've not had a
fractalling fix; the duotone blue/black fractals that xfractint provides in 32
bpp colour are a non-starter.

  Thus I scan this list, hoping against hope, that I'll see an announcement
that a native Linux version of Fractint is available.  I have heard rumblings
and rumours that such a beast was contemplated.  If indeed my Holy Grail is in
development, would some kind genius/developer (aren't they the same?) please
let us Linux fractint fanatics know?

  A while back, there was talk on the list about a project to port the Fractal
Creations manuscript from its current format (MS Word, I believe) to HTML. At t
hat time I had volunteered to co-ordinate/participate in such a project but
never heard anything back, as I had some spare time and copies of both
editions of Fractal Creations.  Did this project ever get off the ground?


Cheers,
Rob

Subject: (fractint) Fractal-Art 2000 Contest Update

Greetings folks,

It's been a busy week for me, as I estimate approaching five hundred
entries in this year's contest. I'm hoping to have them all processed and
available for viewing by tomorrow evening.

Next year I'll just include in the contest schedule a week between the
entry period closing and the entries being posted, so nobody will be kept
in suspense. :)

I'm impressed with the variety of entries this year, and I think the
categories worked very well; there's a more even division of entries than
in previous years. And there are more animations, better animations.

Just a little while longer, and everyone will get to see.

The passes= parameter is forced to passes=1 for any resolution over
2048x2048.  Or, at least it's supposed to be.  Floating point is also
forced.

Subject: (fractint) FOTD  01-10-00  (An Odd Scene [5])

FOTD -- October 01, 2000 (Rating 5)

Fractal visionaries and enthusiasts:

I have time for only a short discussion this evening, since I'm
trying to get the backlog of work cleared up by Monday.

For the image I turned to my archives and a fractal several
months old.  The IkeMandNewt formula that created today's image
is included in the fractint.frm file.  It was written in 1993 by
Ron Barnett, and is most certainly the source of my series of 12
MandNewt formulae.

I named the picture "An Odd Scene" because it reminds me of a
series of bizarre structures sitting alone and forgotten on some
lost planet, doing strange, mysterious things.  The silhouetted
objects may have been constructed by alien intelligences; they
may be natural formations -- we'll never know.

The picture rates an average 5.  I wanted to rate it higher, but
then I remembered that it has already failed once to qualify for
FOTD.

At a render time of under 2 minutes, the parameter file is as
efficient as downloading the image file from:

          <alt.binaries.pictures.fractals>

or from:

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

The fractal weather today was once again perfect, with sunny
skies and a temperature of 70F (21C) that pleased the fractal
cats.  Unfortunately, I had little time to give them a proper
outing, but I made it up to them by treating them to a can of
tuna.

As would be expected under such conditions, the philosophical
ponderings went nowhere today, but next week should be
different.  For tonight, it's time to shut down the Fractal
Central and call it a day.  Until tomorrow, take care, and when
questioned, claim the fractal did it.

This isn't true.

passes= is forced to passes=1 if a disk-video mode won't fit in memory, and
therefore uses the disk. (I think this can be improved upon, by making
disk-video act like automated use of divide-and-conquer in that case,
incidentally. Also, since even a 32768x256 strip of the image can fit in a
modern machine's RAM easily, even the existing system should allow guessing
in truly "disk" disk-video -- except if the image strip affected on a single
line of the first pass won't fit in RAM. Actually it might do this -- I
don't know. All I have observed is that passes=t will be changed to passes=1
if disk-video doesn't fit in memory.)

When I ran that 4096x3072 one, it used tesseral.

> This isn't true.

If you are forcing passes=t with a resolution greater than 2048x2048, please
tell me how you are doing it.  I can't do it on my machine, but I'm too
familiar with the code and don't often think outside-the-box.

Machine memory isn't the issue here.  The problem is that the tesseral,
boundary tracing, and solid guessing routines use a local array of size
2048, and therefore break with resolutions above 2048.  Which is why
passes=1 is forced.

Subject: (fractint) PARS: outside=fmod

Hello all,

For those of you who follow the developer's versions of Fractint, here
is a little parameter file which shows what the outside=fmod option,
added in the latest developer's release (20.1.0), can do.

Or at least, it shows what I can make it do - I'm sure those who are
more artistic than me can make something alot better...

You should be able to start a second X server in 8-bit mode on another virtual
console and run fractint on that.  It shouldn't need an outrageous amount of
memory because you don't need to run a window manager on it unless you really
want to.

Subject: (fractint) FOTD  02-10-00  (For All Eternity [7])

FOTD -- October 02, 2000 (Rating 7)

Fractal visionaries and enthusiasts:

It was another rushed and hectic day here at Fractal Central,
but despite the lack of time, I managed to find a fractal image
worthy of being named FOTD for October 2.

The expression 0.1Z^(-100)-10(1/Z)+C was iterated by the M-Mix4
formula to produce the fractal in which today's decorative
midget lies.  I named the picture "For All Eternity" when, while
studying the scene, I had the thought that this midget, which
almost certainly has never before been seen, always has existed,
and always will exist.  I rated the image a 7, mostly because I
rather admire the yellowish string of features that outlines the
pattern around the midget.

With a draw time of almost 8 minutes, the parameter file is slow
enough to make a download of the image the more efficient way of
viewing the eternal scene.  The image may be retrieved from:

          <alt.binaries.pictures.fractals>

or from:

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

With a temperature of 71F (22C), the fractal weather today was
perfect for cats.  The fractal cats however enjoyed far too
little time outdoors.  A can of tuna this evening eased their
exercise frustration.

Well, I see it's once again time to shut down the fractal shoppe
and call it a day.  I'll return tomorrow with more goodies but
little philosophy, since the continuing rush will still not
allow me enough time for a proper ponder.  Until then, take
care, and where were you when they discovered the Mandelbrot set?

Subject: (fractint) FOTD  03-10-00  (Missing Minibrot [6])

FOTD -- October 03, 2000 (Rating 6)

Fractal visionaries and enthusiasts:

The good news is that I'm within a few hours of clearing the
work backlog; the bad news is that today's FOTD is an extremely
slow one.

Only the stout-hearted will try to run the parameter file of
today's FOTD -- the thing takes almost 13 hours to render.  This
slowness is a result of my choosing a deep scene that requires
arbitrary precision math.  But there is no cause for alarm, for
in my compassion I have posted the file of the GIF image to the
Usenet binary group:

          alt.binaries.pictures.fractals

The image is also available on the Web at the URL:

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

The image is a scene of very large magnitude -- a second-order
midget located quite deep in Elephant Valley of the M-set.  The
midget at the center is virtually invisible, which is why I
named the picture "Missing Minibrot".  The rating of 6 could
have been a 7 had I not made the colors a bit too gaudy.

The fractal weather here at Fractal Central was once again
perfect today, with partly cloudy skies and a temperature of 74F
(23C), which would have pleased the fractal cats had they gotten
the chance to go outdoors to enjoy it.

The work rush cut my pondering time even more than it cut the
cats' outdoor time.  But I'll finish the work mess this evening
and have more time tomorrow to relax and ponder.  And when I
ponder, ponderous things sometimes happen.  So check back
tomorrow, when there's a good chance of finding philosophy.

Until then, take care, and be as quiet as a fractal.

Subject: (fractint) FOTD  04-10-00  (Pods From Space [8])

FOTD -- October 04, 2000 (Rating 8)

Fractal visionaries and enthusiasts:

Today I finally cleared the backup from the week I took off.  I
celebrated by devoting extra effort to today's fractal image.
The formula that was used is once again the MandelbrotMix4; the
iterated expression is -1Z^(-11)-1Z^(1.1)+(1/C), an obviously
whimsical choice.

I puzzled a few minutes before deciding that the picture shows
an army of space pods descending on a defenseless Minibrot.
These pods are not the ones that take over human bodies; these
pods take over Mandelbrot sets.  And if the brilliantly
illuminated midget at the center of today's scene doesn't get
out of the way in a hurry, he'll soon find himself changed into
a pod.

When I recognized the attacking pods, I named the picture "Pods
From Space".  After all, space is the only place such pods could
possibly be found.  I rated the picture a much above average 8,
mostly because I wanted to reward myself for the effort I put
into the image.

I used the passes=b algorithm for today's image.  Not only is it
the fastest, at least in this image, but it is by far the most
fun to watch in action.  I especially enjoy the way the
Mandelbrot outline appears out of nowhere with no hint that it
is coming.

The parameter file renders in only 54 seconds, and running it is
the only way to see the scene being drawn.  But although I
recommend running the parameter file, the finished GIF image is
available as always at:

          alt.binaries.pictures.fractals

and at the URL:

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

The fractal weather today was like mid-summer, with a
temperature of 86F (30C) and a hot sun.  The fractal cats, who
finally had their full day outdoors, approved of the conditions.

The philosophy also made good progress this afternoon, as I
pondered a topic as deep as the nature of reality, which really
is the basic philosophical question.  It will take a day or two
to organize and write my thoughts, but when the wisdom is ready
to enlighten or irritate, nothing will hold it back.

And now, after such an active day, I'm exhausted.  It's time to
shut down the fractal shoppe and call it a day.  If I'm lucky
I'll find a junky old movie to put on the TV, which will enable
me to miss the overblown presidential debate.

But there's no debating that I'll be here again tomorrow with
perhaps an even better fractal.  Until then, take care, and the
best fractals are yet to come.

After a very long absence it looks like I am back to creating some images. I
put up a new gallery dedicated to the season, and also updated my Chebyshev
pages with 24 new images. I invite your visit and I hope you enjoy it.

I uploaded a slightly augmented gfp.ufm formula file to the database and
made it available at my web site too. It is needed for some of the

Subject: (fractint) FOTD  05-10-00  (Dingbats [6])

FOTD -- October 05, 2000 (Rating 6)

Fractal visionaries and enthusiasts:

I expected to have an easy day today, but an unexpected rush job
came in from the Kung-Fu customer, which kept me busy all
afternoon.  As a result, I had to totally forego the planned
philosophical discussion -- and that's reality.  But I still
managed to find a respectable fractal, which I now present as
the FOTD for October 05, 2000.

A dingbat is one of those old-fashioned decorative ornaments,
often resembling leaves on twisting vines, that in the past were
used in printing to mark chapter beginnings, etc.  Something
about today's image reminds me of one of those ornaments, so I
named the picture "Dingbats".

The image rates a 6.  I cannot give it more than that after
spending only 10 minutes locating and coloring the scene.  The
midget at the center is fully resolved -- the distortion is
caused by the exponent of Z, which is 2.01 instead of 2.

The image was calculated by the MandelbrotBC formula, which
draws scenes in the more remote parts of the infinite
hyperspirals created by fractional powers of Z.  The render time
of 10 minutes makes a download of the GIF image file the wiser
choice.  That download may be found on Usenet at:

          alt.binaries.pictures.fractals

and on the web at:

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

The fractal weather today was sunny, warm and humid, with a
temperature of 88F (31C), which was more like July than October.
The fractal cats showed little eagerness to go outdoors in the
afternoon heat, which was convenient, as I had little time to
let them go out.

The philosophy about the nature of reality went nowhere.

The day has now ended with a whimper instead of a bang.  It's
time to shut down the fractal shoppe, comfort the cats, and call
it an evening.  Until tomorrow, take care, and where did these
things we call fractals come from?

Subject: (fractint) FOTD  06-10-00  (Giant Squid [6])

FOTD -- October 06, 2000 (Rating 6)

Fractal visionaries and enthusiasts:

Every time I take hope that the rush is near its end, another
job turns up.  An unusually busy day today left little time for
exploring the world of fractals, so I had to make do with
yesterday's leftovers.  The result was better than might have
been expected.

If today's FOTD looks a bit familiar, it's not deja-vu.  The
familiarity can be explained by noting that today's FOTD is an
outzoom and recoloring of yesterday's "Dingbats" image.  But
instead of dingbats, today's image reminds me of the eight
tentacles of a giant squid.  Yes, I realize that squid have
those two long grabber arms in addition to the eight tentacles,
but we'll ignore them for now, and stick with the name "Giant
Squid".  The rating of 6 might be a bit liberal for my usually
conservative ratings, but it's a respectable image, one well
worth a look.

The image itself shows a typical midget that exists in a spiral.
What makes this midget different is its mis-shapen West Bud,
which has begun to split into two parts.  (This splitting can be
better seen in yesterday's "Dingbats" image.)

With a running time of 6-1/2 minutes, the parameter file is
somewhat slow.  Relief is available however on Usenet at:

          alt.binaries.pictures.fractals

and on the web at:

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

where the GIF image file has been posted, ready for convenient
downloading.

The weather today here at Fractal Central was cloudy and damp,
though no rain fell.  The temperature of 65F (18C) would have
been acceptable for the cats if they had been allowed outside
unescorted.

I'm sorry, philosophy fans, but I had no time to philosophize
today.  I'll try again tomorrow however.  Surely, two days in a
row can't be this busy.  Until then, take care, and take it easy.

I do graphic design work.  The customer, who runs a Kung-Fu school
in the area, needed a newsletter designed and composed in a hurry.
When this customer brings a shoe-box filled with photographs and 27
pages of loose copy, and tells me that he needs it turned into an
attractive 16-page newsletter by the day after tomorrow, it leaves
little time for finding fractals.

Subject: (fractint) Boundery-Trace Algorithm

OK, this stands very little chance of being answered, but hey: if I don't
ask, I won't know...

Most of fractint's passes options are fairly simple. But I was wondering how
passes=b actually works. I've suceeded in finding the section of source code
that does it, and then utterly failed to follow it. I just can't understand
C, that's all. I was wondering if some kind soul could privatly e-mail me
some psuedo code or something... (OK, possibly wishfull thinking here, but
it can't hurt to ask!)

On a related note... The docs say that passes=g is faster usually faster
than passes=b. Is that because for "high detail" areas passes=b basically
boild down to passes=1? Just a thought...

Thanks.
Andrew.

PS. Isn't the new orbit length colour option brilliant?!
