Subject: (fractint) FOTD  12-02-01  (Best of the Lot [8])

FOTD -- February 12, 2001 (Rating 8)

Fractal visionaries and enthusiasts:

For the third day in a row we have an image with no equal
iteration bands on the outside.  Instead, I have rendered the
outside area with the tdis option.  The effect is quite
striking, and rates a slightly exaggerated 8.  I named the image
"Best of the Lot" because I chose it from several fractals I had
filed away for a busy day such as today.

The formula -14(1/Z)+1.4Z+(1/C) created the image, which renders
from the parameter file in a little under 8 minutes.  If running
the parameter file is inconvenient, the GIF image will soon be
available at:

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

and at:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today here at fractal central was sunny but
cold.  The temperature of 37F (3C) kept the fractal cats indoors.

As one may surmise from the brevity of this discussion, I am
very busy today.  I will be busy again tomorrow, but regardless,
I'll still have a fractal to enjoy at that time.  Until then,
take care, and fractals are forever.

Subject: (fractint) C-FOTD  13-02-01  (Pinched-off Midget [5])

Classic FOTD -- February 13, 2001 (Rating 5)

Fractal visionaries and enthusiasts:

It was a hectic day here in fractal land today as the effort to
consolidate Fractal Central and the Fractal Branch Office into a
single location began in earnest.  But it was not too busy to
find a few minutes for fractal fun.

The parent of today's average-rated fractal was created by a
very simple formula: 1.03(Z)+1.03(1/Z)+(1/C).  Z by itself
produces no fractal, and 1/Z produces only a meaningless row of
circular disks, but combined in various portions, Z and 1/Z
produce some quite interesting Mandeloids.

The midget in today's image is located on the tip of an elephant
trunk in the east valley area of a Mandeloid that is ready to
open into a hyperbola.  The features in this area are pinched
almost to the point of being disconnected, which is why I named
the picture "Pinched-off Midget"

It's a very slow image, so I recommend waiting a couple hours
for Paul and Scott to calculate it and post it to their
respective web sites at:

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

and at:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather was sunny but chilly for most of the day,
with a temperature of 37F (3C), which kept the cats indoors.  In
the evening however a cloud bank rolled in, dropping ice pellets
and light freezing rain.

That's it for today, fans of fantastic fractals.  Despite the
continuing hectic activity, I'll return tomorrow with another
fractal.  Until then, take care, and fractals always make things
better.

What the hell kind of video card are you using? Sounds like it's archaic
enough that bank switching occurs when working on high resolution images.

I calculate all my fractals on a separate computer reserved for fractals.
The
CPU in the computer is a Pentium 200mhz.  The video card is an S3 Trio64v2,
with 1 meager meg of memory.

The run times on this machine for the Royal Blue fractal at 640x480x256are:

passes=b -- 2min 9.18sec
passes=g -- 2min 11.44sec
passes=t -- 2min 19.18sec
passes=1 -- 2min 24.51sec
passes=2 -- 2min 24.57sec
passes=3 -- 2min 24.57sec
passes=d -- 2min 27.37sec

Passes=b wins; passes=d comes in last.

Subject: (fractint) C-FOTD  14-02-01  (Fractal Regrowth [7])

Classic FOTD -- February 14, 2001 (Rating 7)

Fractal visionaries and enthusiasts:

All times of year are my favorite times, but early spring, when
the new green shoots are just appearing, is my extra-favorite
time.  Since that time of year is not far off here in the
northern hemisphere, I must have been thinking of spring when I
named today's image "Fractal Regrowth".  Apparently, the
greenish features shooting out from the magenta body of the
image inspired the name.  And the deep blue background is as
close to a spring sky as a fractal can come.

Unfortunately, the equinox is still 5 weeks away, and the
Fractal Central plants are still deep in their midwinter sleep,
and the only spring growth I'll see for a number of weeks will
be on the screen of my fractal-dedicated computer.

The whimsical formula, (all FOTD formulae are), behind today's
image is 0.0005(Z^100)+1.25(1/Z)+(1/C).  This formula draws a
main Mandeloid with a bloated main bud and a few auxiliary mini-
Mandeloids scattered about, which I have not yet investigated.
Today's midget is located deep in the north branch of the
Seahorse Valley area of the main Mandeloid.

The fractal elements in the picture are unusually well defined,
and the colors are unusually brilliant.  These features earned
the picture a well-earned 7 on my zero-to-ten scale of fractal
worth.

The parameter file runs quite a bit faster than yesterday's
dawdler, but still, 23 minutes will set no new speed record.
Relief for the weary is at hand however, and may be found in the
form of the pre-rendered GIF image file on the web at Paul Lee's
web site at the URL:

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

and at Scott Boyd's automated site at:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today featured a cloudy cold morning and a
sunny mild afternoon with a temperature of 54F (12C).  In
response, the fractal cats hugged the radiators all morning and
spent all afternoon lurking in the yard grass, chattering at
the local birds, but catching nothing.

Unfortunately, I had no time for philosophizing today, and I
will have no time until the all-new consolidated Super Fractal
Central is up and running in a month or so.  But I'll somehow
find time for fractals regardless of how busy things become.  In
fact, the next fractal will appear in 27 hours.  Until then,
take care, and when you wish upon a fractal, your dreams come
true.

There are several approaches (each very similar).  You can save the
entire email as a file, or just save everything between Jim's START and
END lines as a file, with the extension of PAR.  Make sure the file is
located in a directory path accessable to FractInt.  After you start the
program, choose the "@" command and then locate the file you saved and
run that selection.

Subject: (fractint) C-FOTD  15-02-01  (Dreaming [7])

Classic FOTD -- February 15, 2001 (Rating 7)

Fractal visionaries and enthusiasts:

Today's quickie fractal image is a nice one, depicting a scene
with a hectic yet strangely peaceful atmosphere.  The word
'nice' is an all-purpose word of mild praise, used when
something pleases in a broad sort of way.  The word fits today's
image nearly perfectly, since the image pleases me in an overall
way, with no specific details that deserve special comment.

The formula behind the image is once again Z^sqrt(2)+C, a
formula that draws fractals with nearly as many surprises as the
Mandelbrot set itself.  Today's midget is located in a curled-up
and cut-off fragment of filament lying some distance from the
main body of the parent fractal.  I named the picture "Dreaming"
when I noticed that it seems to be illuminated by the same
greyish-blue light that illuminates dream objects.

With a run time of 1-1/2 minutes, rendering the image from the
parameter file is the best way of viewing the scene of the day.
Since the picture is nice, I rated it a 7, a nice rating for a
nice fractal.

As always, the GIF image file will soon be available on the web
at the following two URL's:

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

          <http://home.swbell.net/sdboyd56/fotd/>

I will again begin posting the FOTD to ABPF when the new
improved Fractal Central office is up and running.

The fractal weather today was very unpleasant, with rain,
drizzle, fog, and a temperature of 43F (6C) combining to keep
the fractal cats sulking indoors the entire day.

Such unpleasant conditions call for a junky TV movie, so without
further hesitation I'll shut down the fractal shoppe and call it
a night.  Until next time, take care, and when the fog closes
in, clear the air with a fractal.

Subject: (fractint) C-FOTD  16-02-01  (Land of Terraces [8])

Classic FOTD -- February 16, 2001 (Rating 8)

Fractal visionaries and enthusiasts:

Today's image reminds me of a colony of giant worms, like those
in the 'Dune' series.  But worms are not poetic, and I like to
give my fractals poetic names, so I named the image "Land of
Terraces"

The terraces, which line the fractal hillside, were built by the
formula 0.2(Z^2)-10(1/Z)+(1/C), a formula that I pecked out at
random.  The tdis outside coloring option also played an
important part in the construction.

The parent fractal of today's creation is little more than a
giant blob filled with countless smaller blobs arranged in a
pretty much haphazard manner.  Today's image is located in the
center of a large blob near the center of the giant blob.

In addition to earning a much above average rating of 8, the
FOTD image has the advantage of being a fast one, requiring only
a little over 5 minutes to render on a slow old Pentium 200mhz.

At this point I must confess a venial sin.  I post-processed the
image in a separate graphics program.  But my sin has been
forgiven, because I made no changes that could not be coded into
a conventional Fractint parameter file.

The 'tdis' outside coloring option, which was suggested by
XXXXXXXX XXXXXXX, is proving to be a fine alternative to the
classic equal iteration bands option.  I feel I'll be using it
more and more frequently in future FOTD's.

Since I am not currently posting the FOTD to A.B.P.F., the only
way to see the image is to run the parameter file or to give
Paul and Scott a chance to post the GIF image file to their web
sites at:

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

and at:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today was totally miserable for men and cats
alike.  The rain and temperature of 43F (6C) kept both myself
and the fractal cats safe indoors all afternoon.  Tippy accepted
his confinement, but Thomas complained loudly by the back door
until I showed him how wet it was outside.  Then he went to the
side door and started complaining there.

And it's now time for me to be complaining about how late it's
getting and how hard I've been working.  But I won't.  Instead
of complaining, I'll find some more fractals.  The next, perhaps
with a bit of philosophy, will appear in 27 hours.  Until then,
take care, and a cat's gotta do what a cat's gotta do.

Which is typical for most fractals if the video system isn't bank switching.
The algorithm overhead for passes=b is a bit more than for passes=g but
passes=g can easily be seen to calculate every pixel passes=b does and then
some, so on most fractals it will be slower -- the exceptions being
extremely fast low-iteration fractals where the algorithm overhead actually
dominates the compute time and very "busy" fractals where none of the passes
algorithms can find many pixels to skip calculating. Except if the video
system bank switches -- then passes=b can slow down dramatically because it
goes vertically all over the place, triggering bank switches, while passes=g
makes just a few vertical passes down the screen. Bank switching will also
hurt passes=t and passes=d; the big overhead of passes=d over passes=3 on
your system (the latter actually calculates *more* pixels and also draws
filled rectangles) also seems to indicate bank switching. One test of this
will be to do the same tests but in a disk-video mode and see if passes=d
takes proportionately as much longer than passes=3.

I have a recent ATI video card and 400MHz K6-2 processor; at 1024x768, a
particular Mandelbrot fractal takes:

1 minute 0.69 seconds with passes=b
1 minute 4.7 seconds with passes=g
1 minute 30.9 seconds with passes=t
2 minutes 42.47 seconds with passes=1
2 minutes 42.63 seconds with passes=3
2 minutes 43.62 seconds with passes=2
3 minutes 18.43 seconds with passes=d

Looks like my copy of Fractint might not be using its linear framebuffer
modes, hmm...

Sometimes these links won't work with Hotmail -- all you get is a window
saying "There was an error displaying this link". Strangely enough, this
happens consistently with the link in today's FOTD but not happen with the
link in yesterday's FOTD, despite the links using the *exact same URL*.

What can be done about this? It forces me to navigate to the FOTD by means
of a Web search or similar.

in my version of fractint - which i thought would be the newest one - i=
s no
      option outside=3Dtdis available.

Am i doing something wrong=DF

Or am i only using the wrong version?



thanks & greetings

The 'tdis'outside coloring option was suggested by Steve Robinson.
I meant to check and fill it in, but forgot.

Am i doing something wrong▀

Or am i only using the wrong version?

The tdis option was introduced in version 20.0.0  If you are using an
earlier version, you need to download the latest version.  If you are
using version 20.0.0 or later, you are doing something wrong.  I am
using version 20.1.5, but I am not sure that this version is the latest.

Subject: (fractint) C-FOTD  17-02-01  (Broken Doughnut [6])

Classic FOTD -- February 17, 2001 (Rating 6)

Fractal visionaries and enthusiasts:

Some broken titles have a certain class.  Titles such as 'Broken
Blossoms', 'Broken Arrow', or even 'Broken Promises' bear
witness to a coming drama.  But, 'Broken Doughnut'?  What could
be classy or dramatic about a broken doughnut unless one drowned
in their coffee while dunking it?

As for the strange name, something in today's image reminded me
of a doughnut.  Most likely it was the drab green band
surrounding the almost invisible midget at the center.  But the
reason is unimportant; the fact remains that the image has been
named "Broken Doughnut", and that name will be its name forever.

After giving the picture its classless name, I rated it a 6,
which is just slightly above average on my 0-to-10 scale of
fractal worth.

The scene of today's FOTD is part of the Z^sqrt(2)+C fractal --
a fractal that has more nooks and crannies and buds and valleys
than the earth has ants.  Having a fractional exponent, the
scene is almost overwhelmed by discontinuities.  In fact, the
discontinuities are what creates the scene.

The parameter file runs in 10 minutes on a worn-out 200mhz
Pentium, even faster on a more up-to-date machine.  Since I will
not be posting the FOTD to ABPF until further notice, the 10
minute run time can be bypassed only by downloading the GIF
image file from:

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

or from:

          <http://home.swbell.net/sdboyd56/fotd/>

The fractal weather today was totally and unabashedly miserable,
with a steady rain, raw wind, and a temperature of 39F (4C),
which was so obviously unpleasant that the fractal cats were
satisfied to remain indoors, gazing from their favorite window.
(Windows are a cat's TV.)

Since I spent so much time today moving stuff to the new Fractal
Central, I found no time to sit and ponder the mysteries of
existence.  Actually, I need a few new mysteries of existence to
ponder.  The old ones have gotten stale.  So when I get the
chance, I'll have to ponder what to ponder.

Right now, I'm pondering shutting down the soon-to-be-abandoned
old Fractal Central and calling it an evening.  Until tomorrow
at around the same time, take care, and you may already be a
fractal.
