Sorry, I have no idea. I read a book awhile back on the
design of OS/2, but I don't remember the differences.

Some mailing lists now offer a digest version, where all mails to the list
are bundled into one daily mail.  Can we do that with the fractint list?
Those who prefer a daily summary can use that, and those who prefer the
original style can continue that.

Its already been done and has always been there.  To switch from
a reflected subscription to digest, send a message to
[e-mail] with these commands in the message body:

unsubscribe fractint
subscribe fractint-digest

You should then get a message asking you to confirm your digest
subscription (to prevent others from signing you up to a mailing list
without your consent).

Subject: (fractint) FOTD, 06-01-00 (The Lost Rosette) (c)

FOTD -- January 06, 2000

Fractal enthusiasts and visionaries:

Today was another busy one here at the Fractal Central, but not
so busy that I needed to forget the day's fractal.  The rush,
however, meant that I had to call on my faithful MandelbrotMix4
formula to once again produce something in a hurry.

The formula came through with flying fractal colors, as it
calculated the difference between 100Z^(-0.9) and 100Z^(-0.899)
plus 1/C.  I named the picture "The Lost Rosette".  I gave it
this name because while trying a few hasty color schemes I
noticed that with some color palettes the pattern around the
central midget almost completely vanishes.

I assume this vanishing act is due to the image being composed
of a semi-orderly arrangement of discrete dots rather than the
usual equal-iteration bands.  The amber rosette is not really
there; it only appears when certain optimal color palettes are
applied.  But whether the things one sees are there or not, the
image is a worthy one, which earned its place of honor by
appearing when I needed a fractal in a hurry.

I must also thank my dedicated fractal-finding computer for the
fractal of today.  Were it not for this faithful machine, which
has had an obvious hard life, I would never have had the time to
run the unusually slow file on the old 486-DX4.  As it is, the
parameter file takes almost two hours on a fast Pentium.  But
the JPEG image file will soon be posted, (if I can figure how to
use Agent rather than Free Agent), to Usenet at:

          <alt.binaries.pictures.fractals>

and the always helpful Paul Lee will soon have the image on his
web site at:

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

The fractal weather today was everything an early January day
should be in these parts -- sunny skies, brisk winds and a
temperature of 41F (5C).  The fractal cats had no comment.

Due to the rush, I fear I must once again disappoint the hordes
eagerly awaiting the next installment of philosophy. :-(  But
I'll probably get it posted tomorrow -- if not, the next day for
sure.

Until next time, take care, and if fractals are priceless, how
can one put a price on them?

OS/2 cannot run windows apps natively. All the people I have known had
the tools to run windows apps. If I remember correctly, having a few

Subject: (fractint) Updated web site and formula file

Prompted by inquiries about "what parameters to use" with my formulas --
a question too general to be properly answered -- I reworked all of the
formulas contained in my gfp.ufm file. Of course all of them remain
compatible with uprs already generated. What I did was to supply
defaults such that you will get at least a minimal image when starting a
new fractal -- no blank screens! I hope this will help. You can download
the new file directly from the index page of my fractal site (see link
below), but it is also included in the parameter file packages you find
on each of my pages. Please replace all old versions of gfp.ufm with
this one. The file has been sent to Kerry Mitchell, so it will soon be
included in his great compilation.

In addition, I added several new formulas. None, I regret to say for
lack of inspiration, are my own originals, but translations. These
include several gravijul formulas as well as a few of my favorite Sylvie
Gallet formulas from Gallet-3, 4, and 6. A bailout test parameter has
been added to all, since I like the variations made possible by this
addition.

New images along with parameter files using these translated formulas
have been added to my gravijul and Gallet pages.

Your comments are welcome.

Subject: (fractint) new coloring method / new flattening method

Hi,

I would like to present two (in my opinion) new METHODS for fractals.

1. The first is a method to color fractals.
Using outside=iter can often result in very boring fractals with
large monochrome areas.
One way to enhance the image is using outside=atan.
The following code offers an alternative color smoothing scheme
that create effects very different and independent from outside =atan :

;---------------------------------------------------------------------------



colorfrm { ;special colour smoothing scheme by Karl Scherer!
          ; can be applied to ANY EXISTING MATH FORMULA
         loop=0, begin=1, rounds=1 , ;(Karl's additional vars)
         z=0:                        ;your settings
IF (begin==1)
         ;====== insert your formula here =====================
         z=...
         ;====== end of your formula ==========================
         r=|z|-8                     ; equivalent to |z|<8
         IF (r>=0)
           begin=2, rounds=r ; >>> try rounds =r/2 etc! <<<
         ENDIF
ELSE
         loop=loop+1
ENDIF
loop<rounds
}
;---------------------------------------------------------------------------

- ----------------------------


2. The second Method is a method to flatten images that have rotational
symmetry around (0,0).
You can imagine the process as cutting the plane along the positive x-axis
and stretching the sheet such that the unit circle to become the x-axis
and the origin (0,0) spreads out at (any x, - infinity).
A star-shaped pattern for example then turns into a pattern that repeats in
x direction and changes constantly in y-direction (ideal for wallpaper-type
images
and cloth-designs).
You will find totally new appeal in many old point-symmetric fractals,
especially those that
allow deep zooming at (0,0)!


flatfrm  { ; by Karl Scherer (angle,radius) => (x,y)
           ; radius stretched such that (0,0) => (0,-infinity)
          c=pi/5, x=imag(pixel),y=real(pixel)
          x=2*c*x, y=c*y, r=2^(-x), v=r*cos(y),
          w=r*sin(y), p=v+flip(w), {Karl's settings
          z=0:               {your settings
;=========== insert your formula here ======================
         z=...
;=========== end of your formula ============================
         |z|<8000            {your bailout
}

I suggest to Tim Wegener to add to the FRACTINT HOME PAGE a now option
a METHODS besides the existing FORMULAS and PARAMETER
directories.
This METHODS directory shall contain tools, methods (like my coloring
scheme and my flattening scheme), tips and
fractal code that may be used in all sorts of fractals.
I think this would help other fractint users enormously.

Next suggestion: Built my coloring method right into the next FRACTINT
version!

Hi Everyone,

I see speeds of Pentiums going faster all the time. Will a Pentium 700 speed
the generation of FRACTAL images more than say a 350 Pentium would? Or is
there just a point that generation time can't be speeded up any further?

I suppose there is a possibility that it would not, but the
possibility is extremely small.  Almost every fractal I can think of
is what we call "compute bound", meaning that it is being generated at
the limit of the CPU's performance.  (Tasks that are "I/O bound" are
operating at the limit of the I/O devices attached to your system and
aren't sped up by adding more CPU power.)

> Or is
> there just a point that generation time can't be speeded up any further?

If you could generate the image faster than the time it takes for your
monitor to display it (generally 1/60th of a second), then there
wouldn't be much point in computing the image faster if your intent
was to display it.  On the other hand, you could compute images faster
than the display rate for off-line storage and later viewing.

Also, the faster machines get at producing any particular fractal
image, like the classic M-set renderings, the more people add fancy
coloring options, layers, special effects, and so-on until all the
available CPU power is gobbled up anyway ;-).  Just another example of
user expectations going up just as fast (if not faster) than hardware
performance.

For the default 320x200 fractal, the limiting factor for some time for
my setup has been not the time to display the fractal, but the time
for the mode to change from text to graphics. Every newer (and
more capable) monitor I have gotten has been slower. My
Optiquest V95 changes modes quite slowly - seems like several
seconds). And of course when it is finally through changing modes,
the 320x200 fractal is already done!

Yes and no!

The limit is the speed of your graphic adapter. Try the "standard"
mandelbrot using 16 and 256 colors, and you will see that 16 colors is
considerably slower. In this case nearly all the time is used to write
the graphics.
However I don't know if it is of interest generating a image in 3 or 2
seconds. If you want to zoom deeper, increase the iteration limit, use
complex formulas, of course you benefit from the processor speed.

Interesting!  I think some other people have mentioned that they feel
fractint really stresses out their monitor because of the large
numbers of mode switches in a session.  Fractint is being dragged into
the next millenium kicking and screaming, but like Dr. Who is about to
be regenerated :-).

But note that unless you have something like a RAM disk that can buffer all
your fine work, you would quickly hit a bottleneck in disk I/O - something
that is even more of a constraint than video refresh rates.

I/O aside, an "arbitrarily fast" processor would still eventually find it
self bogging down in waiting for things like memory access. But here
sensible design of the motherboard resources should minimise this problem
and would develop in parallel with the faster processors. (Not that that
doesn't prevent some vendors from running overclocked chips on underpowered
boards and advertising a really cheap fast machine).

Subject: (fractint) FOTD, 07-01-00 (Platinum Minibrot) (c)

FOTD -- January 07, 2000

Fractal enthusiasts and visionaries:

While browsing the Fractint list this evening, I came upon a
letter pointing out that the outside=iter option often results
in boring, monochrome fractals.  This is true only if the
fractal itself is boring.  When this is the case, one of the
fancier outside options can indeed be a great help.  But an
interesting fractal is interesting even when outside=iter.
Today's FOTD uses the default outside=iter option, and I would
say that the resulting image is anything but boring.

I named the picture "Platinum Minibrot", though I could have
named it "Silver Wings" or "The Lead Midget", or any of a
hundred other names.  The formula behind all this metal is once
again the MandelbrotMix4, this time calculating
1.1Z^(-1.2)-1.3Z^0.9+C.  The silvery, metallic feel was a
complete accident, appearing at random as I cycled the color
registers.  Only a minor touch-up was needed once I had found
the basic palette.

The parameter file runs in 10 minutes on a fast Pentium 200mhz.
On a 700mhz PentiumIII it will run even faster, but a download
of the JPEG image file is the fastest of all.  That download may
be found on Usenet at:

          <alt.binaries.pictures.fractals>

and on the W.W.Web at:

The fractal weather was sunny and mild today here at Fractal
Central, with an afternoon temperature of 47F (8C) that was
perfect for fractals, cats and philosophy.  The fractal turned
out fine, the cats were happy, and the philosophy has already
been posted to the philofractal list.

And it's now time to shut down Fractal Central as well as the
Fractal Central branch office, and call it another day.  Until
tomorrow, take care, and I wonder what are the odds that the
particular midget in today's picture would ever have been found
and made FOTD.

Now you've got me confused ... What version of Windows
are you talking about? WinOS/2 is IBM's optimized and
recompiled (from licensed source code) version of MS
Windws 3.1. WinOS/2 cannot be run except under OS/2 - IBM
did a major rework of the W31 memory architecture -
WinOS/2 handles memory management for WinOS/2. WinOS/2
comes with OS/2, although you don't have to install it if
you don't want to.

Some W9x application executables (not ported as source
code) have been successfully converted to native OS/2
using a utility and libraries developed by the nonprofit
Project Odin <http://www.netlabs.org/odin/index.html>.
Most publicly know of those convertable apps is the W9x
version of Quake II.

Project Odin is accomplishing this in a couple of ways -
one is a utility that adjusts pointers within the
executable to work properly under the OS/2 memory
architecture and turns a standard W9x executable format
into the standard OS/2 executable format. The most
recent version of that utility can convert standard W9x
DLLs on the fly. (This is similar to something for the
Alpha or SPARC or some other RISC processor - I forget
which.)

The other is by building library DLLs that provide
native OS/2 routines to provide the functionality of W9x
system calls.

I think a well-designed and coded W9x version of a
Fractint DLL would be convertible, but good platform
independent C or C++ code would be better.

Remember - programmers develop to the computer systems
that they're using. No commercial software developer wants
to waste its programmers time, so they get fast machines
to develop on ..

Nope! Programmers like adding things - "Look at this cool

Yet, when you think about it, here we are with extremely
powerful processors, yet we cripple them with MS Windows
9x and its
partly-16-bit-real-mode/partly-32-bit-protected mode
architecture, using the idiotic memory architectures
dumped on us by Intel's idea of a processor .. Methinks
part of the problem is that hardware is much more
advanced than the software that many people use.

Subject: RE: (fractint) Pentium 700

Hmmm, this is an interesting question, as it also would apply to some
software
I have created for multiprecision arithmetic.

There are three pieces to this puzzle:

1)  Internal hardware (video):  These probably won't really be affected =
by
the
    faster PC.  They are constrained to the accelerator used, and at =
these
speeds,
    probably won't see a difference, unless you have a change to a =
faster
accelerator.

2)  Computer memory:  They don't make memory that fast.  So removing =
cache
con-
    siderations, it won't make a difference at these speeds.  Your =
processor
is
    wait-stateing on memory fetches / stores to computer main memory, =
and at
these
    speeds won't see a difference.

3)  Processor / cache:  Now we get to some speed bumps.  If the cache =
is
large
    enough and fast enough, you MAY see a speed difference.  I am =
assuming
you are
    talking about a Pentium-II or Pentium-III style processor when you =
use
the 700
    MHz speed quote.  These processors, to some degree, pipeline
instructions for
    potential multiple instruction execution.  I am not sure what the =
top
limit of
    cache memory speed is, but bumping 350 to 700 Mhz may do something =
for
you.
    If you are looking for 2X improvement, you are probably not going =
to see
that.
    Fractals computation will be faster, but storage of a fractal of =
ANY
decent size
    will probably overflow whatever cache you have and start swapping =
with
the much
    slower main memory.

Of course, the Fractal program would have to take advantage of =
processor
pipelining
to get any of those speed benefits...

Well, that's my guess anyway.  Anybody who has a better knowledge of =
the
processor
and cache capabilities of the Pentium-series chips probably can give =
you a
more
accurate answer!

Hi Everyone,

I see speeds of Pentiums going faster all the time. Will a Pentium 700 =
speed

the generation of FRACTAL images more than say a 350 Pentium would? Or =
is=20
there just a point that generation time can't be speeded up any =
further?
