What you want to fix are the DOS box settings that Windows uses when
running Fractint. Right-click Fractint.exe's icon and choose properties.
The "Screen" tag describes how Windows displays the DOS box (since these
days DOS runs in Windows instead of the other way around). You currently
have it being displayed in a window instead of full-screen. Change that and
it won't do that jumping back and forth to a window any more.

That's the workaround, the permanent solution (work in progress) is to
rewrite Fractint's video code to avoid all the low-level speedups that
assume that Fractint is the only program using the video card. Once upon a
time (like six years ago), this would have been the case, but not now
(since, when run in a DOS box, Fractint doesn't really have access to the
video card, only a Windows-supplied emulation of one).

If you're running in batch mode, and you want to keep Windows running in
the meantime, you could instead try minimising the DOS box window. If
you're not doing anything else at the time, you might want to consider
shutting down Windows, give DOS the processor, and then Fractint's
assumptions about where it's running would be correct.

I have an idea what's going on. I saw that in video modes where drawing the
large boxes that diffusion uses is _lot_ slower than drawing single pixels -
probably the box drawing can't be optimized - that diffusion gives extremely
long times in the estimation, like 10 minutes at first then it finishes in 4
seconds. First, it could be that drawing the boxes in that disk-video mode
is easier than drawing single pixels or at least the overhead of the box
drawing is less than expected (maybe it needs less math with pointers or
less buffer switches? I don't know how that works.) Another possibility is
that the areas of the image where diffusion hits first are faster than
others encountered later.

Try setting the fill color to 0, in that case diffusion won't draw filled
boxes, only single pixels. That fixed the cases where starting the image was
very slow because of the large boxes and the estimations were _very_
'pessimistic', it may change it now too.

Subject: (fractint) C-FOTD 12-11-00 (Wings of Iteration [5])

Classic FOTD -- November 12, 2000 (Rating 5)

Fractal visionaries and enthusiasts:

Rating a 5, today's fractal is one step above yesterday's.  Now
if I can continue this gradual improvement for 5 more days,
we'll have an honest 10 rated image for the 17th.

I named the picture "Wings of Iteration".  It has a certain
airborne feeling about it that inspired the name.  With a
running time of 8-1/2 minutes, the parameter file is a bit slow,
making a download of the GIF image the wiser choice.

As always, the GIF image file may be found at:

          alt.binaries.pictures.fractals

and at:

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

The fractal weather today was partly sunny, though quite breezy.
The 60F (15.5C) temperature was mild enough -- too bad the high
wind kept the fractal cats so skittish that they remained
indoors.

As is obvious by the shortness of the recent discussions, I've
not been inspired to write philosophy for quite some time.  The
reason is that I'm disgusted by the political chaos here in the
U.S.  (Politics is the one thing that can really make me lose my
cool.)  But come tomorrow, I'll have at least another fractal,
even if the words are few.  Until then, take care, and sometimes
the greatest wisdom comes in the fewest words.

Full screen? I don't want it to display full screen, I want it in a window.


Anyhow, I've allready found a solution. (before I do any of this I set a
disk-video mode in sstools.ini)  What I do is open a dos box in a window.  I
cd to fractint, then type the word start (this is my batch file for
animations), but I don't hit ENTER just yet.  I then find another window, it
doesn't matter which other window it is.  I resize the window to a size
small than the DOS box and put it below the DOS box.  Then I go back to the
DOS box, which has the word 'start' sitting at the prompt, and I smack the
ENTER key.  Immediatly, I mean less than half a second later, I click on the
top bar of the misc. smaller window.  This takes the 'focus' away from the
DOS box, and fractint can then be started and shut down from within the
batch file without jumping to full-screen and back again every time fractint
is restarted.

One slight problem: I have to remember NEVER to click on the DOS box, which
will give it the focus.  If this happens, the computer will freeze in a loop
of jumping from full-scren to window to full-screen to window etc...

My only other question is:  Why haven't they updated the windows version to
20.0??  version 18.21 for Windows was greatly dissapointing, as it was
severely stripped down in its features. (no batch mode?  No pallete cycling?
no pallete editor???)

I would LOVE to see a full-featured windows port of dos version 20.0.  This
would eliminate screwing around with DOS settings to force it to behave like
you want it to.  Is there ever going to be a windows version?

Subject: (fractint) C-FOTD 13-11-00 (The Cosmic Mystery [6])

Classic FOTD -- November 13, 2000 (Rating 6)

Fractal visionaries and enthusiasts:

Today we continue our day-by-day climb up the ratings ladder
with a fractal that rates a 6.  The iterated formula subtracts
Z^(-6.666) from Z^(-6.66) and multiplies the minute difference
by a factor of 19999 before adding 1/C.

The result of this operation is a rough open circle with a
shallow bay at its east edge.  The circle is filled with a ring
of fractal islands, the most interesting island lying in the
east bay.  Today's midget lies at the tip of the negative tail
of a larger midget that lies near the center of this east bay
island.

I named the picture, which is filled with comma-shaped elements,
"The Cosmic Mystery".  The reason I gave it such a name eludes
me.  I suppose there's something mysterious about it, a
possibility heightened by the rather somber dark blue color
palette.

The parameter file renders in a little more than 5 minutes.  A
quicker way to see the mystery is to download the GIF image from:

          <alt.binaries.pictures.fractals>

or from:

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

The fractal weather today featured sun, clouds, wind, and a
temperature of 57F (14C).  This combination was barely
acceptable to the fractal cats, who spent only 15 minutes out of
doors.

The day is finished; tomorrow is ready to begin.  It's time to
shut down the fractal shoppe and call it a night.  Until next
time, take care, and see you in 24 hours.

Subject: (fractint) C-FOTD 14-11-00 (Ignacio [7])

Classic FOTD -- November 14, 2000 (Rating 7)

Fractal visionaries and enthusiasts:

With today's fractal we continue the one-step-a-day climb to the
fractal heights.  Perhaps with a bit of exaggeration, I rated
today's image a 7.

The scene exists in a remote (but not too remote) part of the
infinite logarithmic spiral that is the fractal created by the
simple formula Z^1.43+C.  All fractals in this range are filled
with discontinuities -- branch cuts if that's what you would
call them.  These breaks frequently spoil an image by cutting
right through the most interesting part of it, but sometimes the
breaks become so pervasive that they form their own patterns.
Today's image consists entirely of such fractal bits and pieces.

I named the picture "Ignacio".  Once again I cannot justify my
choice -- I simply like the sound of the word.  As is the case
in most of my fractals, a minibrot lies at the center of the
screen.  This midget is typical of midgets when the exponent of
Z in the generating formula is in the range of 1.43.  The midget
is immediately identifiable as a minibrot, but its shape is
distorted almost beyond recognition.

The scene is filled with smaller midgets, one of which sits on
the longest filament.  If this smaller midget is interesting, I
might pull it up and declare it FOTD in a coming post.

The color palette of today's image features a cloud of fiery
foreground fragments floating before a hazy blue background.
The draw time of the parameter file is 6-3/4 minutes on an aging
Pentium 200mhz machine.  As is always the case, the GIF image
file can be downloaded in one minute or so from the Usenet
binary newsgroup:

          <alt.binaries.pictures.fractals>

It will soon also be available on Paul Lee's web site at the URL:

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

The day's weather featured lots of clouds, a raw wind, and a
temperature of 54F (12C) -- unpleasant enough to keep the
fractal cats snugly indoors, wishing they could be comfortable
out in the yard.

And I wish I could find that philosophical muse, which seems to
have deserted me.  I'll try to philosophize tomorrow.  If I
fail, I'll still have a fractal.  Check then to see what
happens.  Until next time, take care, and see you soon.

Ugh, yuck, bleah, money, credit cards, greed, exclusion, elitism...thank

If you can put up with the frequent crashes, you might succeed in
accomplishing something (by sheer luck and serendipity) after about 72 hours
of knob twiddling. (Note that when UltraFractal crashes, it doesn't simply
pop up an "illegal operation" box and die, leaving you at your desktop, with
your other work intact and one double-click away from being back in the
fractal business. Oh, no. UltraFractal doesn't do anything in less than an
"ultra" way -- including crash. When UltraFractal has an ultracrash, the
whole machine locks up hard. The power switch is the only recourse.
Doubleclicking that cute mandelbrot icon while you are typing up your resume
in Word 97 is playing Russian roulette with your career prospects...)

>Almost all of the formulas folks have written for UF can be downloaded from
>http://formulas.ultrafractal.com/

...and then used in ChaosPro 2.1 by the computer-savvy and those with
resumes and money they'd like to actually keep, as well as those with
resumes and no money or at least no credit card who have yet to discover the
wonders of astalavista.box.sk...

I think seeing your first ultracrash is even more instructive, especially
when you've stumbled onto the ChaosPro 2.1 Web page...
show me an experienced UltraFractal user, and I'll show you a current
Fractint/ChaosPro user.

(In all fairness, I can understand how difficult it can be to debug a crash
that locks the machine hard -- no crash traceback, no core dump, no useful
debugging information, even if you put debugging commands in to log the
values of suspect pointers to a file, you'd end up with a zero length file
after the reboot, and no information -- I've tried to debug these kinds of
crashes before. Nonetheless, an app that dies that horribly and that
frequently is simply not release-worthy -- if worse comes to worst they
should just revert to an older version and reimplement the latest features
from scratch, taking great care with their use of pointer arithmetic...some
use of C++ and its standard library templates should cut down on pointer
problems and crashes. And then there's always Java...)

Funny, most things cost money.  It's certainly nice when programmers
create freeware products, but you're rather arrogant to expect it.

Regardless, is that justification to promote theft?

I can show you dozens upon dozens of experienced UF users.  Most of which
are former Fractint users.

FYI, I've used UF extensively for more than two years.  It very, very
rarely crashes.  Certainly not as frequent as you describe.  I'm sure
most users can report the same.

I too have used UF extensively for two years. To the best of my
recollection, it has NEVER crashed.

Subject: (fractint) C-FOTD 15-11-00 (Infinite Regress [4])

Classic FOTD -- November 15, 2000 (Rating 4)

Fractal visionaries and enthusiasts:

I had hoped to have a fractal that rated an 8 for today, but
alas, such lofty images are difficult to find, and I lacked the
time to do a proper search.  Forced by circumstances beyond my
control to substitute an fractal of lesser quality, I settled on
today's image.

Today's fractal features a midget.  This is nothing unusual,
since nearly all my fractals feature midgets.  This particular
midget is found in the fractal that results when the expression
- -Z^(-13)-10Z^(-1.3)+1/C is iterated.  It's a fairly routine
midget, lying in an area that at first appears non-critical.

The fractal detail surrounding the midget is lively enough, but
it just doesn't make a pleasing impression.  The colors are
brilliant enough, but seem haphazard, and lack an organized
theme.  As a result of these deficiencies, I have rated the
picture a lowly 4.  I named the picture "Infinite Regress",
though this name would seem more appropriate for one of those
endless spirals.

Taking 11 minutes to render, the parameter file tries one's
patience.  But immediate relief in the form of the already-
rendered GIF image file is waiting on Usenet at the binary group:

          alt.binaries.pictures.fractals

and soon will be waiting on the web at:

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

The fractal weather today here at Fractal Central was rainy in
the morning, followed by clearing in the afternoon, with a
temperature of 55F (13C) that was fair enough.  But the wet
grass kept the dynamic duo of cats confined to the porch.  It
appears that fractal cats don't like to get their paws wet.

No philosophical inspiration has yet appeared.  I'll see what
happens tomorrow.  Until then, take care, and cheer up with a
fractal.

    "Colours of Infinity",  a 1-hour video
         (usually airs on local PBS stations)
    The following quote was taken from this website:
          http://www.kcts.org/whatson/magazine/12_98/colours.htm
      "Dr. Arthur C. Clarke, screenwriter of 2001: A Space
          Odyssey and inventor of the space satellite, chronicles the
          1980 disocvery by Dr. Benoit Mandelbrot of a geometrical
          shape which can be used to better understand the physical
          world. Clarke explores this doscovery's impact on the world
          of mathematics - which has included the development of a
          new mathematical discipline: fractal geometry - with the
          help of Dr. Mandelbrot, Prof. Stephen Hawking, Dr. Michael
          Barnsley and Prof. Ian Stewart. Set to a musical score by
          David Gilmour of the rock group Pink Floyd, vibrant computer
          graphics help the audience visualize the M-set and illustrate
          its infinite complexity. Clarke predicts that the next
          generation of devices, which will be built on fractal
          principles, will revolutionize communications, health care,
          the military and computer technology."

I have never experienced a crash using UF, and I've also been using it
for more than two years.

I am also a firm believer that things should be distributed at cost,
creating a fair trade. When something is distributed over the Internet, that
cost is unmeasurably small (probably measured in thousandths of a cent),
given that a few bucks of electricity and about twenty bucks a month for
network access is all it takes to keep a server up for a month, during which
tens of thousdands of downloads can be made. Even distributed on CD, the
cost is maybe two bucks per copy, which makes it all the more ridiculous
when you see music disks, disks with Windows 95, etc., for twenty and forty
and even sixty bucks.

Obviously, you're using a different version. ISTR the 1.something versions
being decently stable. 2.04, however, displays a nasty habit of locking up
the operating system usually within the first five minutes of trying to use
it.

It depends on how much IP there is in the program.  If I'm the programmer and
I have 1000 hrs in a product... and I can only sell a small amount of copies...
then
do the math.

I agree that if the work is someone else's... then the price should be fair.

I'm happy to pay a reasonable price for something I actually use.  Fair pricing
reduces piracy by a large amount. Economic Rape encourages it !!!
