Hi Les

Publish and be damned (please!).

For a few months I've been a lurking spectator who has contributed
nothing to the fractal world (yet?) but I enjoy and admire your work greatly.
I find PFE makes tidying up your posts easy and recommend it to anyone
having trouble with extra characters etc. (are you listening Angela?).
I can't claim to have discovered PFE - I think it was Jay who mentioned
it some weeks (months?) ago and I now use it for all my editing, saving
etc. of pars and frms from the list.

The fireworks are going off outside (UK) - perhaps I should get  a life!

Happy New Year to all of you who have introduced (seduced?) me into
your fascinating world of fractals.

John Evans

Merry New Year to all.

Thank you to Damien M. Jones for a quick answer to a nagging question.

Thank you to Janet Preslar for the flattering request.  No I do not
have a web site, but I'm working on it (so many porcupines - so little
time!) Sample pars should arrive in your e-mail later today.

Angela aka wizzle;  I can't give you a better understanding of math
but I do suggest that you read Bradley Beacham's formula tutorial - it
realy helped me get a beginning grip on some of what is going on in 
the formulas tho Sylvis Gallet's stuff still sails by at an altitude
much greater than my height. (first you crawl, then you walk, then you
run :-)).  A zipped copy is included in Fractint ver 19.6 and there is
a hyper-text copy at the spanky web site.  <<hugs>> to you too.

When I save a file in windows notepad, with the frm extension, it looks OK
from file manager, but inside winfract it is read as a txt extension, and
subsequently does not appear to be read by the programme as a formula file.
Anyone else with this problem, or any suggestions.
I have spent the last two days of the new year holiday trying to do my
first fractal from a par file from the mail list, and not there yet, but
still trying

Beth  - set notepad's "files of type" to "all files(*.*)"  and you should be
able to save
your files with no further trouble ( though you will have to reset the "all
files" setting
each time you open notepad since it defaults to "text files".  If I find a way
around that, I'll let you know

Date: 01 Jan 1998 11:22:11 -0500 (EST)

I am running Fractint on a pentium with plenty of ram. It's running fine in
both DOS and as a window, except for one problem. It pauses for a full
second between screen switches, all the text menus and the image. During
the pause the screen is black. The monitor makes a click that sounds like
a relay switch at this time. This happens independent of any textsafe=
options, and is independent of video mode. The graphics card is an nVidia
4MG AGP graphics card. I'm told by someone with a PII 266 from a different
company that they have this same problem and just got used to it, but I
find it maddening that my 486 is much faster. Does anyone have a clue
about this? Thanks!--Alice

Beth....

Use "file .....save as" instead of save....then enter the filename with the
frm or par extention.  That was happening to me too and is an annoyance.
You can re name the fileneme with the .txt (looks like formula.frm.txt)
portion of the name in windows explorer (the magnifying glass thingy) but
that is ..... I agree...a pain. Warning....do NOT use file manager in
win95....it has some nasty peculiarities...use explorer instead. In
explorer you will see the garbaged up name and can make the changes easily.

Your pars are too good not to be posted....what about trying a different
provider???  You can easily locate one in your area by shopping at

www.thelist.com

There is an option to find providers by entering your area code.  And any
decent provider will have you switched over within a matter of hours.  The
going rate is $20 per month, unlimited time with 5 megs of homepage space.

Alice,

I have exactly the same situation since I upgraded to my Pentium II with a 17"
SONY monitor and a Diamond Stealth video card with 4 mgs of VRAM.

I've spoken to SONY and Diamond Stealth.  I've been assured that the clicking
is not harmful and that the screen delay is normal in DOS programs.  I'm not
really convinced in either case, but I went through 2 other brands of 17"
monitors and they all did the same thing.  

I can get rid of the clicking sound by changing the refresh rate for the
monitor from Optimal to Default which still works fine for Windows apps, but
then the pictures don't generate properly in Fractint.

Sorry, that's all I can offer.  

Bill

I still can't open the phoenix formula that Paul Carlson so kindly

formula....but I keep getting error (5) undefined function (I think).

However....I have made progress.....if only in a sideways direction....I
also can't open 3d_balls from Jay.  Same error code. Maybe I need something
to add to Fractint to do if statements??? This seems the common denominator
for my problem. I downloaded and installed a fresh copy of Fractint hoping
that that would solve the prob.....

I know since I had at least 4 versions (working for those that sent them)
that the par and frm files have to be ok.  And I know that it is the frm
that is causing the error. sooooooo......I MUST be missing something in
Fractint....anyone have an idea what I might need????

    I have now set the mail program to send plain text, so that should be
that problem sorted out.

    Yes you are absolutely right, the thumbs werent really thumbs at all,
but I now have thumbs prepared and am about to upload them, so they should
load much more quickly now.

    As far as the use of Pauls formula and par, the notes say no commercial
use without permission, my use is not commercial.  I think its a really good
image, however if paul objects I will remove it.

  C'est demande si gentiment!!!! :-)

  The formula for Moebius Star is available in my gallet_3.zip file.  Her=

it is:

Gallet-3-05 { ; Sylvie Gallet [101324,3444], 1996
 z =3D pixel , c =3D p1 , bailout =3D real(p3) :
 test =3D (flip(c*z) >=3D 0)
 a =3D (z-p2)*test , b =3D (z+flip(p2))*(1-test) , z =3D (a+b)*c
 (sqr(real(z)) < bailout) || (sqr(imag(z)) < bailout)
}

  And here is the formula for Firespiral:

Gallet-9-02 { ; Sylvie Gallet, sylvie_gallet@compuserve.com, Aug 1997
              ; Bailout: real part of p2 (must be > 0)

   z1 =3D c =3D pixel , mz1 =3D cabs(fn2(z1)) , k =3D real(p1)*mz1
   bailout =3D real(p2) , z =3D imag(p1) :

   z1 =3D fn1(real(z1)) + flip(imag(z1)) , mz1 =3D cabs(z1)

  Tha latest par you posted has "reset=3D1950" which means you're using
Fractint 19.5.  Paul's formulas as all the formulas that use if..else
statements require Fractint 19.6.

Subject: SECRETS of the par and frm  was Re: (fractint) Binary decomp...?*
Date: 01 Jan 1998 13:18:50 -0800

Hi Fractintiers,
Happy New Year.

I hop this Decomp algorithm is not too boring to anyone, 
but I'd like to see this settled.  I post the same request 
for help from the formula gurus who hold the SECRETS 
of the par and frm ever so tightly. :-)

Here is a slightly changed version of the frm. I have 
determined that a very large bailout is required. In fact,
a bailout of 4 screws up the usual decomp image produced 
by Fractint (I complained of this before).  

I have created a special web page to display what we 
could be seeing if these frm ever work. There you will 
find a program and images displaying the correct, IMHO, 
decomp at level 2.  Here is the C++ version of the 
algorithm:

int Maxiter=256;
int ColorPoint(Complex c){ 
// Decomp (c) by Jay Hill 1998 
  int color=0; 
  Complex z=0; 
  for(int k=Maxiter; k>0; --k, z=z*z+c) 
     if(norm(z)>1048576.) 
       return real(z)>0?RED:LIGHTCYAN; 
  return color; 
} 

I have experimented in C++ with decomp 256. If we get 
this one working I can then make correct, IMHO, decomp 
256 images. I could be wrong, but the symmetry in the 
Fractint formula prevents its use in field line tracing.

http://home.san.rr.com/jayrhill/Decomp.html

Could Damien, Paul, Les, etc. (you know who you are) 
please take a look at this? 

Thanks.

Jay

  Therefore, with z =3D w-iter instead of z =3D w, the formula should wor=

but it doesn't!  And it works with z =3D w-iter-8...  WHY?????

  z =3D w - iter - 8
ENDIF
iter =3D iter + 1
done >=3D 0              ; Continue if the flag >=3D0.

Hi Les -- I've been following your trials and tribulations and wonder what it's
all about.  I don't think the problem is entirely at your end.  I get your pars
and run them with no editing and no problem.  I'm using Netscape's Communicator
4.04, copy directly into the Programmer's File Editor, separate the .frm's from
the .par's, and put 'em in appropriate Fractint subdirectories.  My ISP is an
East Coast USA outfit called Erols, but I can't tell you what mail software
they use.  I've had very little problem with anybody's .par's and .frm's,
especially since going to the PFE (thank's for the lead, Jay).

Actually, I only have vague recollections of a Top Ten
Reasons Why Fractal Enthusiasts Should Be Watched
Carefully, or something of the like.  It might have gone
something like this:

Top Ten Reasons Why Fractal Enthusiasts Should Watched
Carefully
by Jason Hine

10) The statement, 'I is my favorite number,' makes perfect
sense to them.
9) For some reason, they value mold, dust, flakes, and
dripping faucets.
8) To them, a great use for an expensive computer is to try
to model the above.
7) If it's broken, they won't fix it.  They like it that
way.
6) Have you heard the stuff they call music?!
5) They prize random formulas which produce graphs no one
understands.
4) One word: ZOOMERS
3) They believe in imaginary numbers.
2) Two words: ESCAPE TIME

... and the number one Reason Why Fractal Enthusiasts
Should Be Watched Carefully:

1) They spend years writing awesome software, then give it
away for free.

Hope you like 'em... :)  Jason

True, but if you have an external Zip drive, you can take it with you and attach
it to
(almost?) any computer... so I'd say just don't get an internal Zip drive!

Yes. I currently have a 17" NEC monitor mated w/"GTI" 'puter containing ~6

I would love to have an example of this - the PAR file and what 
resolution in how many pieces gave you the problem. If the problems 
are debugged then simplgif would do the trick.

I will send the PAR file next week
the interesting thing is I repeated the procedure 3 times and got basically
 the same error each time.

I was working with a 4 x 4 split-up of a gif file.
When I tried 3 x 3 it worked file and 5 x 5 worked fine but 4 x 4 refused
to work properly.

I had worked on 8 other 4 x 4 images that day all worked fine it was just
one particular
gif file that would not work.

Alice,

 - Does anyone out there have a large new monitor that does NOT having this
 - problem of screen delay in DOS with clicking?--Alice

My experience with dozens of PCs, using small and medium-size monitors (17"
is medium :), is that newer monitors generally have about a one-second
blackout while switching modes.  I've not seen a new monitor that did not
have this feature.

Ordinarily, this isn't a problem, because most software doesn't change
modes often.  Only DOS programs like FractInt that require you to
frequently switch between text and video modes.  If FractInt's text
displays could be overlaid on its graphics screen, it would save a lot of
wear and tear on monitors; I have killed a monitor twice by rapid switching
of modes in FractInt.  (It was not FractInt's fault, just that that's the
only app I've got where I can get switching modes two or three times per
second!)

Subject: (fractint) Re: decomp FRM
Date: 01 Jan 1998 19:20:58 -0600

Jay,

 - I have created a special web page to display what we 
 - could be seeing if these frm ever work. There you will 
 - find a program and images displaying the correct, IMHO, 
 - decomp at level 2.

I'm not sure the image on your web page is entirely correct, but with the
suggestion Sylvie provided, I get an image very similar.  I too have
noticed that you need to subtract 8 or so from z when using outside=real in
order to get the color you expect.  I do not know why this is so, but it's
possible this was a fudge factor introduced in FractInt to make
outside=real to produce aesthetically pleasing results when used with
normal fractals. :)

My goal in working with decomposition has been to *absolutely* retrieve the
field line of an escaped point.  Your FRM provides only the least
significant bit.  _Chaos and Fractals_ indicates that successive bits of
the field line approximation can be read off by simply continuing to
iterate; when I try that, though, I run into some problems.

My first problem is that I *do not want* the values retrieved to be
discontinuous at integer dwell boundaries.  I want something that is
totally smooth and consistent, regardless of the number of iterations
performed.  The FRM you have posted doubles the frequency of apparent field
lines with every extra iteration.  This is no good for me.

_Chaos and Fractals_ indicates that the first iteration provides the most
significant bit of the field line, based on the sign of the imaginary
component.  As long as I don't actually add in bits derived from iterates
with magnitudes less than 1048576, this works fine for me--I get accurate
results.  But I *need* those higher significance bits.  For example,
consider this modification of your formula:

J-decomp1 { ; Binary decomp (c) Jay Hill 1997
            ; modified by dmj 1998
            ; use outside=real
  done = 1, iter = 0     ; Iteration flag.
  weight = 1, w = 0, b = 2^4096
  dummy=maxit            ; forces float=yes
  z = 0, c = pixel:      ; Mandelbrot initialization.
  z = sqr(z) + c         ; Mandelbrot calculation.
  m = |z|
  weight = weight * 0.5
  IF (m >= 1048576)      ; Point exceeds threshold.
    IF (imag(z) > 0)
      w = w + weight     ; Color 2 on the other
    ENDIF
    IF (m >= b)          ; Point exceeds bailout.
      z = w*1024 - iter - 8 ; fixed color scale
      done = -1
    ENDIF
  ENDIF
  iter = iter + 1
  done >= 0              ; Continue if the flag >=0.
}

Here I keep a running weight, which indicates the decreasingly significant
"bit" that each iterate provides of the field line.  These are accumulated
to w or not, based on the sign of the imaginary component.  Note that
because bits are not "counted" until the magnitude (m) of z exceeds 2^20,
points closest to the M-set have their most significant bits forced to
zero.  For close-in work, where I want the colors to repeat quickly (and
the more significant bits are effectively lost anyway) this might not be a
problem, but in practice it still seems to be causing problems.  For fun,
try changing the 1048576 to 0 and use a full 256-color palette.  Points far
from the M-set (where the iterates reach high magnitudes quickly) show
smooth gradations of color, indicating appropriate field line
approximation.  Up close, though, things get twisted and gnarled; the bit
test is yielding inaccurate results.

Do you know of any way to extract the appropriate bit of the field line
from iterates of low magnitude?  As I indicated in my previous post, if I
do this on a Julia set, it works *flawlessly* as long as imag(c) = 0.  The
farther imag(c) is from zero, the more messed-up it gets.  This affects the
M-set, of course, because each point is pulled from a Julia.

The 15" ViewSonic that I use _does_ have the relay clicking but it has not
been a problem (it's also slightly less than a second). In fact, the only
monitor that has ever given me grief was the only one that _didn't_ have it.

As far as Fractint _pausing_ during mode switches; are you sure that it
does? I frequently find that once the monitor has finished switching modes,
Fractint has already been drawing as if there had been no delay at all.
With a "g1" preview, for example, the image is sometimes completed (with
sound effects and all) before the monitor has finished switching.

The only delays regarding mode switching that I have experienced are the
occasional pauses in refreshing the image as a result of the
"textsafe=save" option. I may have to wait a second as the image is painted
back on the screen using the default colour map and then reloading the
palette. If the pause you're experiencing is genuine, could this be its
origin?

texsafe=save causes the entire graphics screen to be saved and 
restored to a text file. This could result in a pause at high 
resolutions when switching between graphics and text modes.

My monitor pauses significantly during video switches without any 
help from Fractint. By the time the monitor is through blinking, the 
default 320x200 mandelbrot is done <g!>

Subject: (fractint) Re Field lines, monitors and CompuServe mess...
Date: 01 Jan 1998 20:36:16 -0800

Hi guys,

I am coming up out of DOS to see the email. I've been 
making field lines. More on that later Damien. My web page 
shows the BINARY decomposition. I agree getting the 
exact line needs more bits.  All bits, IMHO, can be gotten
in one simple equation involving log(z).

About the monitor delay. I have a new NEC MultiSync XV 17+
and only get delays at modes above 1024x768.

Sorry for the off-topic here but I'm using MS Internet explorer 
email reader on an cable modem (very fast) and I have not 
seen the mess-up you all are referring to.  I assume that if 
it is real, the remainder of this post should show it. Does 
any one see anything wrong with this post? I leave Les' here 
for you to see. It came in fine. So I conclude it is not 
CompuServe!  Or did MS finally get it right, it can read 
garbage?

Jay

(BTW it is 11:38. If this thing bounces but goes through at 12:01, we'll
know for sure about the list having some kind of offpeak time restriction.)

Les, here is another report on your pars.  I received all of them completely
without "spurious garbage."  However, in all of them some lines, and in Happy
New Year! all lines were double spaced. I certainly don't mind editing your
pars, however. I generated all of them. Great images!  HNY!, both the image and
the formula, are amazing!  Gedeon.

I apologise for the HTML, I just assume that everyone can read it, I have no
problems with HTML mail, obviously Im wrong.  I sent another message about 5
minutes later with the URL.  In case you didnt get it its:-
                    http://homepages.iol.ie/~bagpuss/

Again I apologise for the mixup.  As for newbie, im fairly new to fractals,
but i have been using Email since before there was a World Wide Web, back in
the bad old days when VMS/CMS was the norm, and UNIX was heavensent!

Stephen....

Your original email came thru to me looking like an email....but I have
gotten some that looked like html code now and again.....I always wondered
what was happening and now I have a glimmer ........what email program do
you use that makes code like that??

Didn't you ask about pointers for color maps???  I think I forgot to
answer.....the way I got started was by reading Linda Allison's
lessons.....they are posted at my website.  My first color maps were really
pathetic so I used hers for a while until I could relate a map....and what
I wanted to achieve....with the fractal image.  But I'm still
learning....and I usually spend time looking at the color maps that are
generated by folks here.....I've gotten lots of great ideas....especially
from Paul Carlson.

Not even attempted yet. ProtoMatter hasn't reached that stage. The first

You seem to be thinking of binary decomp. I'm thinking of the process of
decomp, binary, then 4-fold, up to Fractint's limit of 256-fold, carried
to the limit.

Did you get a new monitor? Some monitors are faster and quieter at syncing
different modes than others. (Modes with different numbers of pixels down,
require the monitor sync to change. Text is usually displayed at 640x480.
You may be fractalling at 1024x768 or something. So the scanlines changes
and the monitor changes frequency every time you switch modes.)


Note: ProtoMatter will remain in graphics mode throughout execution, so
this problem won't exist with it.


Have you tried using the old monitor with the new machine?

Subject: Re: (fractint) Formula Question
Date: 02 Jan 1998 05:32:49 -0500 (EST)

>Is it a geometry thing? Or Trig? *sigh*

No, no, it's not geometry or trig... it's far, far, worse.

It's calculus.


<listens to various modems hanging up and NO CARRIERs popping on people's
terminals, one heart attack, two burst cerebral aneurysms, and five
nervous breakdowns>

Okay, those of you still listening: The best formulas for iteration have
multiple critical points; places where the deriuvative (consult your
entry-level calculus text) goes to zero. The rest have one, but never ever
ever zero.

Take the regular M-set formula. It is z^2+c. The derivative is 2z, which
is zero when z is zero (twice nothing's still nothing). Thus, it has one,
so there are fascinating julia sets more than likely (and indeed there
are) and an M-set. The Julia sets are obtained by fixing a value for 'c',
different for each Julia set, and varying z to get an image:

z=pixel, c=p1:
z=sqr(z)+c,
lastsqr<p2


The M-set is had by setting z=0, the critical point, and varying c:

z=0, c=pixel:
z=sqr(z)+c,
lastsqr<p2

Now look at the formula z^3-3*c*z+c. The derivative is 3z^2-3*c, or z^2=c,
or z=+/- sqrt(c). Thus there are two critical points. Each gives an M-set:

c=pixel, z=sqrt(c):
z=sqr(z)*z-3*c*z+c,
lastsqr<p2

c=pixel, z=-sqrt(c):
z=sqr(z)*z-3*c*z+c,
lastsqr<p2

And Julia sets like so:

c=p1, z=pixel:
z=sqr(z)*z-3*c*z+c,
lastsqr<p2


Also, to avoid a solid black screen, make sure the thing will tend to
infinity for some z!
Polynomials of at least 2nd degree work. Any Newton formula or twist upon
same will work. Any rational where the degree of the numerator exceeds
that of the denominator, or a term that increases with z is added to the
quotient, will work. Trig works because the sin and cos functions go to
infinity for large imaginary values, even though the familiar sine wave is
bounded. That bounded wave is only what goes on on the real axis and isn't
the whole picture.
Logs go to infinity, but too slowly. The derivative should exceed the unit
circle for z bigger than some bound. This means the modulus of f'(z)
should be greater than 1 for z with a modulus exceeding a certain bound.

Note that some formulas e.g. Newton don't adhere to these rules much! They
generate stuff because they still have many attractors. But since all are
finite, things are trickier. You must spot the finite attractors and make
an orbit trap aroun them:

PlainNewton {
  z=pixel:
  z2=sqr(z)
  z=z-(z*z2-1/(3*z2)),
  |z-1|>p2
}

This is the Newton iteration for z^3-1, with an orbit trap around 1. The
last line before the lone close brace is the orbit trap.

For a Newton fractal, an orbit trap of a different type works:

  z2=sqr(z)
  diff=(z*z2-1/(3*z2))
  z=z-diff,
  |diff|>p2

This catches all three attractors. Because the difference between the old
and new z is "diff", if diff gets close to 0 and stays there, z has hit a
point attractor. This thus traps orbits around all three attractors.

If you are unsure of the locations of attractors, or they vary based on c
or are too complicated to bother with (like two of the three in the Newton
iteration above), just trap for a z that stays put:

  oldzed=z
  z=...etc.etc.etc.
  |oldzed-z|>p2

(Note: All of these use p2 as a bailout. If p2 is left the default 0
expect blank looks from your computer! Literally. Instead set a small
value, like 0.001, and use float=y.)

By keeping older zeds:

olderzed=oldzed
oldzed=z
...
|z-olderzed|>p2

you can trap for both fixed point and 2-cycle attractors, whilst making
false alarms with 2-cycles less likely.

Note that for orbit traps around finite attractors, often periodicity=0 is
needed to get a picture at all, or else to get rid of bogus black squares.

You can trap for longer cycles without doing any work at all by
capitalizing on Fractint's periodicity checking. This time leave
periodicity ON! All you have to do is have no orbit traps at all (except
maybe at infinity), count iterations (iter=0, ..., iter=iter+1,...), and
then on termination have your thing set z to iter on the last iteration,
or 0 if iter==maxiter. Generate using outside=iter, inside=zmag, and
you'll get any infintie basin colored by iteration, any finite basins
colored by iteration, and points that never were trapped by periodicity
cheking colored color zero.


When you're making formulas, calculus is your friend.

It may have been about fractal formulas in general but it had examples as

Sorry, Paul, but IMHO 25 posts in 8 hours, most of them useless, is SPAM.
As for your calculus explanation I doubt whether anybody with less than a
postgraduate maths degree understood more than a couple of words.

1.  How big can a file of formulas be? 

2.  If I change the location of the formula from
say....formulafile=fractint.frm ....to web1.frm and change the par
accordingly, will this work?  I would like to keep all the formulas I get
here together and still make the pars work. I assume I put my formula file
where fractint.exe is, right?

3.  Is there a limitation on the size of par files?

Hi,
    Having spent some time playing with the 3DBalls frm by Paul Carson, a
thought struck me.  How easy is it to adapt this formula for other types?
Could you use it for a Julia? Could you use it for the INSIDE of a Mandel?
could you use it to spice up relatively "monochrome" types, are the
possibilities really endless?
    If I could understand how the damn formula works I'd have a go myself,
but I cant work out how the hell it works (anyone like to throw me a
tutorial?), so if someone with more skill than me could have a go........

Subject: (fractint) BEJ Formulas
Date: 02 Jan 1998 09:33:07 -0800

I downloaded a bunch of pars from the Spanky site ....among them Brian
Jones'.  I would very much like to see them, but I am missing the following
referenced formula files.  

formulafile=bjbcmod3.frm 
formulafile=bj2.frm
formulafile=builtn01.frm
formulafile=bjsg-g-1.frm
formulafile=msg-1.frm
formulafile=bjbcmod4.frm
formulafile=bej.frm
formulafile=bejmod~1.frm
formulafile=bjbcmod2.frm

I noticed that Sylvie very sensibly made Gallet.frm (which was avaialbe at
Spanky) as the single point of reference for her par file.  

Which leads me to a suggestion....could we have some sort of naming
convention for the pars and formulas posted here???  So everything could go
into a single file .......say 98list1.frm, 98list2.frm......etc.  Not only
would this help organize...but also save hard disk space since even a 1k
file actually takes up something like 40k of disk space (at least in win95).  

Thanks for your help.....

Paul,

 - Anyone else notice how a lot of very weird (and very LONG) formulas with
 - strange new abilities are coming out now that 19.6 has the If-Then clause?

With IF-THEN, formula-writing becomes more like programming.  I think just
about everything that you could do with IF-THEN, you could do before with
expressions multiplying a Boolean expression (x < 0) by some other
factor--but using IF-THEN makes a faster formula.

One reason formulae are getting longer is because people are commenting
them more. :)

Wizzle asked:

> 1.  How big can a file of formulas be? 

All the different kinds of files that have entries (formulas, PAR, 
lsystems, and IFS) are limited to 2000 entries. This only applies to 
the user interface that displays the entries in a scrollable list. I 
believe that it doesn't apply when Fractint is used in batch mode. 
However, IMHO, the 2000 limit is way big enough, and users are well 
advised to partition their collections. George Martin has written a 
great program called Orgform that helps manage your formulas. I 
recommend it.

You can specify a directory as well as a default file in the 
formulafile= line. Fractint will try very hard to find a formula, and 
will look in every formula file in that directory. If none is 
specified, the current directory is used (not necessarily the 
directory where fractint is.

Fractint's ability to search for formulas is a mixzed blessing. It 
CAN mean that Fractint will find the wrong formula with (accidently) 
the same name. Hence the importance of George's program. From time to 
time we have big discussions about what Fractint should do, but so 
far we haven't figured out something better.
 
> 3.  Is there a limitation on the size of par files? 

2000 entries. There's also a limitationon the size of each individual 
PAR and formula entry. We had to bump up the limit to accomodate 
Sylvie Gallet, who writes formulas that spell out words <g!>

Mail software interacts with messages both at composition time and at
delivery time.  Some people have mail readers that can handle
printed-quotable and they do the decoding.  So it displays fine in
such mail software.  However, not everyone has mail software that
understands the printed-quotable encoding.  To that software, every =
appears as =3D, which for fractint par and frm files is quite
annoying.  The reason it is suggested turning it off is to accomodate
those people who don't have mailers understanding printed-quotable.
Also, if the mail message is viewed as a plain text file, the =3D's
will be everywhere.  In the case of fractint par and frm files, there
really isn't any reason to use printed-quotable, because we don't
typically use 8-bit characters such as european accented characters in
par and frm files.

Date: 02 Jan 1998 11:47:35 -0600

Angela,

 - 1.  How big can a file of formulas be? 

I'm not sure what the upper limit is, but I've got one that's 178K and
FractInt handles it fine.

 - 2.  If I change the location of the formula from
 - say....formulafile=fractint.frm ....to web1.frm and change the par
 - accordingly, will this work?

Yes.  FractInt looks first in the file specified by formulafile=, but if it
can't find the formula there, it will look through ALL the FRM files it has
for the formula.  So even if you forget to change the formulafile=, it will
still work.

 - I assume I put my formula file where fractint.exe is, right?

Put the FRM file with all the other FRM files.  If that's the directory
where FRACTINT.EXE is, then that's where it goes. :)

 - 3.  Is there a limitation on the size of par files? 

Don't know about that either, the biggest in my PAR directory is 100K.
That seems to work fine.

Subject: Re: (fractint) 3DBalls question
Date: 02 Jan 1998 13:31:52 -0600

Stephen.

 - Having spent some time playing with the 3DBalls frm by Paul Carson, a
 - thought struck me.  How easy is it to adapt this formula for other types?

Somewhere in the formula will be a short section which is the real fractal
calculation.  The rest is the coloring stuff.  Change the guts, and you've
got the coloring technique applied to a different fractal.  As
well-commented as Paul Carlson's formula was, I don't think you'll have any
trouble.

 - Could you use it for a Julia?

Yes, but keep in mind that you need a parameter for Julia sets (unless you
embed it in the formula).  Most of my coloring formulae use all three
parameters, leaving no room for Julia exploration. :(

 - Could you use it for the INSIDE of a Mandel?

For any type which stops iterating early, coloring the inside the same way
as the outside is automatic.  But if you're using a coloring technique
which allows iteration to proceed normally, you have to keep track of the
number of iterations and stop one iteration before maxit if you want to be
able to specify a color for inside pixels.  You also end up having to turn
periodicity off, so that FractInt itself doesn't bail out early on those
interior points.  Basically, you have to fool FractInt into thinking all
the inside pixels are outside pixels.  See any of the -I variants in my FRM
file:

    http://www.geocities.com/~fractalus/misc/dmj-pub.zip

 - could you use it to spice up relatively "monochrome" types, are the
 - possibilities really endless?

Yes, the possibilities really ARE endless!  I have 100+ variants, plus
another batch I'm working on which aren't ready for "release" yet--one of
which I posted earlier.

 - If I could understand how the damn formula works I'd have a go myself,
 - but I cant work out how the hell it works (anyone like to throw me a
 - tutorial?), so if someone with more skill than me could have a go...

OK, a basic formula in FractInt works like this:

MyFormula {
  <initialization stuff> :
  <per-iteration calculation>
  <keep-iterating test>
}

The <initialization stuff> is where you put everything that needs to only
be done once per pixel.  For example, a Mandelbrot version would include z
= 0, c = pixel and nothing else.

The <per-iteration calculation> is where you put everything that must be
done for each iteration.  Our Mandelbrot example would just be z = sqr(z) + c.

The <keep-iterating test> part is the very last statement in the formula.
If it evaluates to anything other than zero, the formula keeps iterating;
the point hasn't bailed out.  A Mandelbrot would use something like |z| <
4, which has the value 1 ("true") when |z| is less than 4, and value 0
("false") otherwise.

Now, how you turn this into a "coloring" formula is a little trickier. :)
The basic trick is that FractInt provides several coloring modes which use
not just the iteration value where a point bailed out, but also the final
iteration value.  For example, with outside=real, the outside color is
defined not just by the iteration, but by iter + real(z) + 8.  (The 8 is
the fudge factor mentioned in other posts.)  Now, if we write the formula
so it watches for when z bails out, and stuffs in a phony real(z), we can
completely control the color FractInt uses to plot any given point.

Here's a simple example.  This is a stripped-down version of
dmj-Mand-Pnt-Dst from my FRM file:

dmj-Mand-Bof60 { ; outside = real: bof60 coloring, but outside

  closest = 1e+38                  ; Closest approach so far.
  done = 0                         ; Iteration counter.

  z = 0, c = pixel:                ; Mandelbrot initialization.
  z = sqr(z) + c                   ; Mandelbrot calculation.

  done = done + 1                  ; Done one more iteration.
  d = |z|                          ; Compute distance to p1 (squared).
  IF (d < closest)                 ; Closer than previous value.
    closest = d                    ; Save the closest approach.
  ENDIF
  IF (d > 128)                     ; Point exceeds bailout.
    z = sqrt(closest) * 75         ; Apply color scale.
    z = z - done - 8               ; Return value.
    done = -1                      ; Set flag to force an exit.
  ENDIF
	
  done >= 0                        ; Continue if the flag is clear.
}

The basic idea behind the coloring algorithm bof60 is to determine the
closest distance the point gets to the origin.  So in the first block,
where variables used by the coloring algorithm are set up, the "closest"
distance so far is set to a huge number.  "done" is used to count iterations.

The next block is the actual fractal calculation.  The initialization stage
is completed in standard Mandelbrot fashion, and the actual iteration code
follows immediately--again, standard Mandelbrot iteration.  This formula
uses the Mandelbrot set!

In the next block, the iteration counter is updated.  Then, the distance
for the currently iterated point is computed (|z|).  If this distance is
closer than the previous closest distance, the new closer distance is saved.

The last IF is actually our bailout test.  If z is too big (remember, d is
the distance of z from the origin) then we need to bail out.  The first
thing that is done is to compute a new value for z--we are stuffing the
color value we want in here.  sqrt(closest) is what we are basing our color
on, and the 75 is an arbitrary scaling factor.  The next line takes out the
other values FractInt uses with outside=real; we don't want those items, so
the formula subtracts them and FractInt adds them, and they cancel out.
The last line in the IF sets "done" to -1, which the very last of the
formula uses to tell whether or not to bail out.

Hope this helps get your started!

I improved that textured mandel image by improving the texture
lookup quality and anti-aliasing it.  The PNG file went on a diet as a
result and dropped 75K in size.  At first it seemed a little strange
that the PNG file would decrease in size with anti-aliasing, but when
I think of the details of how PNG stores the picture data, it makes
sense.  At any rate, I think the image improved quite a bit as a
result. :)

I was mentioning the other day to someone starting a homepage that your
page is an example of truly fine web style.....as well as containing
magnificent images. You have very crisp layout....good
navigation....attention to bandwidth....all the essentials....it's really a
page worth studying for how well it's put together.  No need to
blush......but r40, b20 and g05 does produce a nice (frac) tint for blushing.

If you are using Netscape 4.0, that may be the problem. Apparently Netscape
4.0 doesn't like the Javascript there that plays the fractal music -- even
though all of the functions used are from Netscape's own Javascript site. It
seems to work with everything else, including Netscape 2.x, 3.x, Internet
Explorer 3.x and 4.x. I guess I need to change the Javascript. Will let you
know when its ready. You might like the image called "Fertility"

Maybe the following will assist in your search:

______________________________________________________________________
G. Keith Still BSC is a graduate in Physical Sciences from RGIT
(Aberdeen).  In the 1980's he was involved in the design of computer
systems for electron microscope imaging and chemical analysis.  He
developed computer systems for environmental data capture and analysis -
Compliance Manger - and linked them into virtual reality for
visualisation of data in four dimensions (including time).  That work
led to the development of the VEgAS (Virtual Egress Analysis and
Simulation) system - modelling egress from burning buildings.  This
system has been reviewed internationally, with Keith appearing on
various television programmes worldwide, and producing articles for
national and international magazines and journals.  Keith has lectured
at many organisations, including the Fire Research Station and the Fire
Services College, Morton-on-the-Marsh.  VEgAS was the runner up in the
innovation of the year award in 1992. 

Keith sold VEgAS to an international fire and ventilation company.  He
then went on to created FMIG Limited and developed a more powerful
system LEGION that uses the Orchid fractals, a discovery he made while
recuperating from an operation on his back.  LEGION uses "entity
oriented programming" and handles 250,000 individuals.

Orchid Fractals have applications for currency market analysis, data
compression, data encryption, data analysis, digital fingerprinting and
crowd dynamics analysis.  LEGION has received international coverage on
European Business News and a variety of science magazines including the
New Scientist and Reuters. 

Keith is currently registered at Warwick University (under Professor Ian
Stewart) for a PhD in Mathematics.

What do three parameter fractals look like?
The three interdependent functions are expressed as objective, motility
and constraint.  This applies to a wide range of interactive systems
from crowd dynamics to ecosystems modelling (Objective can also  be
expressed as a function of some environmental change). Using phase space
diagrams to illustrate these as two dimensional objects, to Keith's
delight, they produce rich, beautiful and very complex shapes.

The author named these Orchid fractals (the internal shapes reminded him
of an Orchid).  They map the interactions within this type of dynamic
systems.  It would require a trained mathematician to use the
relationship between geometry and dynamic systems within the Orchid 
phase space diagrams and to non-scientists they are just pretty shapes.

However, Keith's entity oriented programming technique's use these
fractals to map these interactions inside a virtual reality model that
is more understandable than a phase space diagram.

Some curious phenomena of Orchid projections are that, when applied to
some mathematical functions (for example the stock market) they distill
out strange attractors.  They produces shapes, full of detail and
mini-bifurcations but self-organising as if there was a higher order,
limiting function holding them together.  Applications for these
algorithms include data compression, data encryption, currency market
analysis and digital fingerprinting techniques.  Keith is currently
developing a series of applications using the Orchid Fractals.

Aw, come on Paul. We were all newbies once and most of us are
still newbies at something. I'd rather give newcomers some
helpful advice by private email than ridicule them publicly.

If I was shot down for all my mistakes I'd have died from
embarrassment before I got started!

Thank you. Six months ago I thought HTML was a four letter word
I hadn't heard yet. Only a couple of months ago a number of
readers of this list gave me valuable advice in correcting
a browser width problem I had. If *I* can do this it means there
is hope for us all.

I'm just putting the finishing touches on a complete redesign
of our gallery pages. It is much slicker with a (I think...)
unique way of exploring the gallery. A few more images and
larger pics. The bandwidth will suffer a little but such
is the price of style. Sigh...

Thanks again. I'll tell Margaret :)

Well, I tried again today - the Fractint list is still bouncing
all my email back to me, so could I impose upon you again to send
the following for me?  I think you'll like this one - it's kind
of cute.  Thanks.  Paul

The par file that accompanied my 3D_Phoenix_Spirals formula that
Lee Skinner posted here for me some time ago produced a rather "elegant"
fractal.  The par file below produces my favorite 3D_Phoenix_Spirals
fractal -  I think it has a real "whimsical" quality to it.  It looks
to me like the thingy on the left is saying to the thingy on the
right, "Hello there, haven't I seen you someplace before?"

Date: 02 Jan 1998 20:27:12 -0800

I hope someone can help with this- I  have been reading
all the posts about saving par files and  I am
still having problems with some of them.  I would really
like to get 3D_balls by Paul Carlson - it sounds like it
is fun and I would like to get the images from the pars that
other people have made out of it.  Les St. Clair's don't seem
to work either.  ( The New Year message worked ok in the
attachment.)  Nearly all the other pars and formulas work now.
I am using Netscape 4.04 and Fractint 19.6, and I open them
into Pfe32 and save them as whatever.frm or .par. (into
 the same directory as Fractint without defining exactly where
it goes) and it sometimes it  seems to hunt for a formula but usually
finds it. ( I thought I was doing something wrong but so many of
them do work that I think this is probably not it- duuuhhhh!)
(Maybe it's my brain- ohhhhnooooooooooooooo)
Maybe it is the server or maybe it would work better in the
earlier version of Netscape.  Can someone re-post  (or send
to my address)  3D_balls  and I can see if it works better in an
earlier version of Netscape, or any other suggestions would be welcome.

Having looked at Damien Jone's formulas (and even having a go at removing
IF-THEN operators as he describes - oh yeah, it can be done, but who would
_want_ to?) I reckon one approach to shortening formulas (and formula
files) would be to introduce file inclusion. Then one wouldn't need to
repeat the same code multiple times one for each variant; just write it
once and insert references where it's used. Something like
"include(initlib.frm/variant1)" perhaps, which can be abbreviated to
"include(variant1)" if variant1 is to be found in the same .frm file as the
formula using it.

Just a thought: it would shorten dmj-pub a fair bit, and would make adding
new bailout/colouring formulas a lot easier, and would allow interested
readers to concentrate on the relevant parts of the code more quickly.

Feeback, anyone?
MLO.

I think it's a great idea. The only problem I foresee is that
right now people have trouble regenerating images from
pars because they are missing formulae and/or colour maps.
It might just aggravate things if they have to worry about
missing inclusions as well.

Hari Seldon??? :-)
Must be an Asimov fan. :-)

I dunno if this is the same fractal, but I saw a fractal calendar with a
picture titled Orchid on it, the picture was quite obviously Newton's
method to solve e^z-1=0.

That would be: z_new = z - (exp(z)-1)/exp(z)
or z_new = z-1+exp(-z).

Try putting an orbit trap around 1.

Good point - and I wouldn't want to have to scrabble through and make sure
all the inclusions are good before posting a par. It's hard enough now just
keeping track of where the original formula and colour map is coming from.
Perhaps an option on the par saving screen for making a par file suitable
for pasting into a post - attaching a frm:-prefixed formula, doing all the
inclusions, explicitly writing the colour palette etc.


>>Feeback?
<Sigh> lovely thought...

Post Scriptum:
I've just noticed something odd. I was being bounced a bit back there and
now I remember having changed the address I'm posting to from
"fractint@lists.xmission.com" to "fractint@xmission.com" and it worked.
Maybe I should change back and see if I still get through.

Morgan,

 - (and even having a go at removing IF-THEN operators as he describes - oh
 - yeah, it can be done, but who would _want_ to?)

Only someone who has to get such a formula working on an old version of
FractInt... :)

 - I reckon one approach to shortening formulas (and formula files) would be
 - to introduce file inclusion. Then one wouldn't need to repeat the same
 - code multiple times one for each variant; just write it once and insert
 - references where it's used.

This is a *fantastic* idea.  As long as I could put included snippets in
the same FRM file, and FractInt had an option to automatically assemble all
the FRM pieces needed for a PAR, this would be *excellent*.  Yumyumyum.

What a positively splendid idea.

I have updated my web page with some new truecolor images, and for those of
you who would rather not hear fractal background music, there is a control on
the bottom of each page which allows you to turn it off. The Windows 3.1
version of Truemand uses the new exponential smoothing truecolor method for
anyone who would like to see how it looks.

Ron,

These are very interesting pictures.  Some of them look like they use
various "orbit boost" techniques, particularly ones like Whirlpool.  Aside
from the smooth coloring :) how were they created?

 - The Windows 3.1 version of Truemand uses the new exponential smoothing
 - truecolor method for anyone who would like to see how it looks.

I put together a quick FractInt FRM to mess around with the technique--it
is most effective, even in 256 colors.  What's particularly impressive is
that it works for types like NovaM, where I've been trying in vain to apply
Linas Vepstas' algorithm.  How does the exponential color value relate to
the iteration value (or does it)?

Subject: (fractint) Field lines, binary and Trinary decomposition
Date: 03 Jan 1998 21:29:23 -0800

Hi Fractintiers,

In the last month there are at least two threads, maybe 
three, on this topic mixing and folding, in the true spirit 
of chaos and fractals.  References below are to posts 
to this forum in the last few weeks.

I hope you enjoy the formulas and pars.

Jay

        Field Lines, Binary and Trinary Decomposition
    (c) Jay Hill 1998  (as if anyone would want to copy this...)

1) There is the question of how to plot binary decomposition. 
One way is as posted, matching existing text books. That is 
choosing black or white depending on whether the bailout z is 
above the real line. Fine, but the alternative, left/right of the 
imaginary axis just shifts the phase of the black-white blocks 
and has the interesting effect of somehow correctly mapping 
the real line. Indeed, the midgets and buds on the real line 
have a numbering scheme based on this method. But as 
mentioned, it breaks down for complex midgets and buds. For 
these, a different boundary is needed. And it is not the imaginary 
axis. It is at an angle depending upon which field line you are 
following. Worse still, the boundary (for coloring black or white 
based on z) is not always straight!

2) Another thread is the issue of extending binary decomposition 
to more bits. I claimed earlier that the approach Paul Derbyshire 
suggested will not work. One reason is the curved boundaries 
mentioned in 1). In the early iterations, the real line boundary is 
not a good substitute.  Paul is trying to estimate the external 
angle corresponding to c in z<-z^2+c.  The best way to get the 
external angle is iterate to bailout and measure the angle of z. 
That is,  angle = imag(log(z)).  There is an ambiguity because of 
the number of iterations used to get to bailout and the actual period 
of the field line.  Yes, every field line has a period, namely, the 
period of the component it leads to. This brings up a problem with 
binary decomposition. The lines defined by binary decomposition 
have no period. The lines (follow the radial boundaries of the 
checker pattern) seem go to chaotic points. So, to extend binary 
decomposition to 256 levels, follow z to bailout, set the color to 
256*[imag(log(z))/(2*pi)].

3) A third thread is how do we follow field lines. That is two 
problems, how to plot them and how to follow them for pan and 
zoom. We can start with what we know from 1) and 2).  Now 
we must choose a set of field lines to plot and they must 
all have the same period (leading to components having the 
same period). Otherwise we are back in the problems of binary 
decomposition, namely colors scrambling at each iteration boundary 
curve (the ones that go around the MSet - not radial).  So we can 
choose the simplest interesting case, period 2.  There are two field 
lines going out to 120 degrees and 240 degrees from the base of the 
period two bud (-0.75).  The shape is like an hyperbola. So the 
method is iterate and select color based on the three regions. One 
wrinkle, we must do two iterations in each loop to keep the pattern 
from scrambling.  So here is a frm and par to do just that and plot lines.

frm:J-decomp3 { ; Trinary decomp (c) Jay Hill 1997
                    ; One boundary leads to -.75
                    ; Another boundary leads to +i.
done = 1               ; Iteration flag.
iter = 0               ; Sylvie Gallet's suggestion
z = 0, c = pixel:      ; Mandelbrot initialization.
z = sqr(z) + c         ; Mandelbrot calculation.
z = sqr(z) + c         ; Mandelbrot calculation.
IF (|z| >= 100)        ; Point exceeds bailout.
  done = -1            ; Set flag to force an exit.
  y=.5*imag(log(z))/pi
  IF (y<0) 
    y=y+1 
  ENDIF
  w=3*y
  z=w - iter - 8       ; Sylvie Gallet's suggestion
ENDIF
iter = iter + 1        ; Sylvie Gallet's suggestion
done >= 0              ; Continue if the flag >=0.
}

The par files are at the end.   This can be extended to the next level 
and so on......  I have chosen color banding so you can follow a few 
of the lines all the way to the component base.

Instead of getting involved in the new age thread, I was off from work for
2 weeks making my own statement of fractal/new age philosophy.  See if you
can find in on:

Hi All,

  Yet another formula and par from Paul Carlson!

        - Sylvie

Here's another formula quite similar to the 3D_Phoenix_Spirals
formula I sent some time ago, the similarity being that both
formulas use a variation of the ATAN method.  I've added a
couple of PAR files that produce images that I like.  Don't
be put off by the maxiter=3D5000, they both execute quite fast.

Hi All,

I've been making fractals for five years and on the internet for two. So
why no Fractal web page?
I dunno!

Anyway, it's there now!

Find it at:  http://ourworld.compuserve.com/homepages/Les_StClair/

There's two galleries of Fractint images, plus all my par files & formula=

to download.
There's also galleries of Flarium24 and Fractal Elite images (am I allowe=
d
to mention them here?)
Not only that, but a Fractal eXtreme movie too! (which you can see "live"=

on your browser if you're using Netscape Navigator 3 or Internet Explorer=

4).

Have a nice long phone call!

cheers, Les

Jim....

I'm not sure what you want to know about color maps....but Linda Allison
has two excellent lessons on using and making them which I host at my web
site....

http://wizzle.simplenet.com/fractals/fractalintro.htm

These lessons are easy to understand and full of examples. I liked them so
much I asked Linda if I could host them so they would always be
available......also take a quick look at my Fractint hints which gives the
very basics of grabbing a color map from an existing image.  

Angela aka wizzle

ps.   you are welcome to download any of my gifs and use my color maps

How do you like Flarium?? (did I say a bad word)????

Angela,
They may be helpful if you want to make maps from scratch, so to speak,
without a particular fractal in mind.  In addition, Mapmaker can save (or
convert) map files in the csv format, which can then be graphed and
manipulated in interesting ways in Excel.

Humpf....

I do that anyway with Fractint based on what I learned from Linda.  I've
been able to figure out how to make maps that "do" things in a general way
(like carving out areas of black) then do very minor tweeking for
particular images.  What I like about Linda's explanations is she say HOW a
map enhances and image...not just the mechanics. 

But the excel part sounds interesting.....and I know we all learn in
different ways....do you have examples of stuff before and after excel
manipulation?? I can only understand what I can see.....not technical
explanations.

In a message dated 98-01-03 18:28:11 EST, you write:

<< These are very interesting pictures.  Some of them look like they use
 various "orbit boost" techniques, particularly ones like Whirlpool.  Aside
 from the smooth coloring :) how were they created?

The formula for WhirlPool is actually quite ordinary. Its the standard
Fractint mandel(fn||fn). Here is the equivalent Fractint par file. This will
generate the same image, but with the banding characteristic of Fractint:

WhirlPool          { ; .                                     t=  0:02:25.72

  }

Some of the images do use a variant of the Pickover orbit trap method. The
variant allows coloring to give a more 3D effect, and a user variable to
determine how close to the x or y axis the orbit must be to be trapped. The
coloring is based upon both the iteration count and how close the orbit is
when it is trapped. I am thinking about incorporating some of Paul Carlson's
great methods, since it would be a simple add-on to my current code.

>> I put together a quick FractInt FRM to mess around with the technique--it
 is most effective, even in 256 colors.  What's particularly impressive is
 that it works for types like NovaM, where I've been trying in vain to apply
 Linas Vepstas' algorithm.  How does the exponential color value relate to
 the iteration value (or does it)?
 
  >>

As far as the relationship between the iteration count and exponential color
value, I have done some empirical exploring running the compiler in the debug
mode but have found no clear relationship. For low iteration counts the
iteration count may be 10 fold or so larger. As the iteration count increases
it looks like the exponential color value might converge towards the iteration
value. For some of the images on my page, the ratio is less than 1.5. This
might be an interesting area to explore mathematically. Note that for
WhirlPool the Fractint coloring based upon the iteration count and exponential
coloring are quite close. All I had to do was to rotate the palette a little
bit.

Thanks, everyone who is using Makemap. By the way, any fractint map, including
the ones created with Makemap, can be readily brought into Excel by using
space as the delimiter rather than comma (csv).

Special note to Angela: Makemap can create maps, both by the Fractint
approach, and it can also use four different algorithms to design a complete
map (sine, fourier, HSI and RGB). It runs under Windows 3.1 and 95. I haven't
checked it under NT.

Getting there slowly

to the left of reset.
Saved in fractint/pars

elegance           { ; by Angela 1997 using deeps7.map
  reset=1950 type=formula formulafile=bessels.frm formulaname=BESSEL-2

THis is the frm file, saved in notepad via edit, in order to retain
the frm extension. Notepad will only save as txt.
Saved as BESSELL-2.FRM in fractint

      c = z = pixel:
         z = cos(z) / z + pixel,
      |z| <= 100
}

Am I right so far?
I still get an oops message, and can't parse that formula

Is there a way for the pars to load automatically, or does one always type
them in manually

THanks,
Beth

I may be doing this all wrong, but what I do seems to work fine for me. Due
to limitations of notepad I have .frms' defaulted to WP. In the above
formula, I suspect a little bit was missing: first line after   Bessel-2 I
added:  (after the "{"  ; Bessel2

It now works fine.

The .par, after inserting into .par file also worked fine. (got rid of the
">'s".

(>Is there a way for the pars to load automatically, or does one always type
>them in manually)

For what I am doing, still using windows, I highlight the entire thing, hit
ctrl-c, bring up where I am going to put the item, then hit ctrl-v. Saves a
lot of typing.

Beth, you save the whole thing, starting with the "Q" in QuartzM2C (which
is the name of the formula) and ending with the "}", which marks the end of
the formula.

Not sure I understand your question, but the way to change parameters while
a par image is drawing is to hit "z", which brings up the parameter screen.

Hey that's mine:)

Save the whole thing in a .frm file.

Save the above in quartz.frm and read in the par with the @ command.
It will find the formula and use it without difficulty.

Bud,

 - Do all formulae have to be expressed in terms of Z, or can I separately 
 - process real and imaginary components?

It's best to use "z" because FractInt looks at z to check for periodicity.
If you don't use z anywhere in your formula, FractInt sees that z is in a
tight periodic loop (all zeroes) and bails out early.

If you want to calculate the real and imaginary values separately, you'll
just have to write the formula to run that way.  It's a little cumbersome,
but can be done.

Subject: (fractint) Par
Date: 05 Jan 1998 19:12:43 -0500

I believe I mentioned I should be posting a par due to a slightly off topic
post a few days ago. There is nothing complex about this one, a slight
change in one suggested parameter and using one of my color maps, but I
kind of like this one. Please direct flames to the nearest IRS office
(USA), and tax collection agency of your choice outside of the USA.

Subject: (fractint) Phractal update
Date: 05 Jan 1998 19:30:30 -0500

What is it about the new year that we all feel compelled
to change things? Yep, our pages have changed too.

A few new images, but all are larger now. Mostly a new
non-linear way of viewing the pics. Highly organized
types may still view things in a systematic manner. But
now you can simply "wander" through the images. I hope
you do because different image sequences might produce
different experiences.

Take a look and tell me what you think. The old pages
still exist and are linked, but the gallery is now
essentially separated from them.

Speaking about links, if any of you would like me to
provide a link to your pages, let me know. Your pages
need only be fractal oriented and free of any
prurient or prejudicial content. Other than that,
we're an equal opportunity site :)

The old pages remain at:
http://www.globalserve.net/~jval

The gallery is now at:
http://www.globalserve.net/~jval/phractal.html

I've had a few people ask why they couldn't read other
peoples' comments. I decided to add a previous comments
page but am still not sure how I feel about this. If
I've quoted you and you'd rather I didn't, let me
know.

Oh, and I've slightly modified the old pages. If anyone
using a wide browser screen experiences problems, please
let me know.

Thanks for your time, people!
Regards - Jack

 THis is the frm file, saved in notepad via edit, in order to retain

 Saved as BESSELL-2.FRM in fractint
 

Beth -  this looks good except you have to name the frm file BESSELS.FRM since
that is what the par file is looking  for.  Or change the formulafile= to
BESSEL-2.FRM    

But the formulaname agrees though, so that part is good.  (You can have more
than one formula in an FRM file.  See the difference?)

See my other message to you.


One more advanced point that will make it much easier for you to play around.
Change COS in your formual to the variable fn1.  When you call up the formula
using T as I explained in the other message, you will then be able to hit Z
and change fn1 to COS or SIN or TAN or anything else without leaving Fractint
and writing another formula. 

Let me know if you have any more questions.

Hi dear Fractinters,

Got no objection against the large formulas, they produce amazing images.
But I wanna know who is able to invent the SMALLEST .frm (the letters
between the { } are counted) that produce lovely images... in combination
with the very many features of Fractint (y/x/z screens)? Good stuff for a
little contest..?

;-)

Have fun,

and a happy New Year!

Keeping up with the Joneses is one thing...but now I'm forced to keep up
with the Valero's too!!!  I'm really glad the images are larger,
though...it was my one concern. I just adore all your comments....don't
EVER change that approach. I'm envious of all your html tricks but too lazy
to learn how to do them......and flame frames.........the perfect answer to
making a 19" monitor look just like a 14" one!!!Like are we doing graphics
here or cute web tricks??? Glad you haven't succombed to the temptation to
add those 2@#$%@!!! things to your website. They only take up precious
space that is better devoted to your wonderful fractals....

attention contest administrators!
While cleaning up my e-mail archives I discovered the following set of pars
which seem to have been submitted on time but never showed up in the contest
displays or among the par file collections made available.  I know all this
went on rather quickly and without much organization but I can't help but
think that the graphic specialist couldn't feel too good about being ignored.
I'm sorry I didn't find this soon enough to get this person included,but I'm
not that organized either,

Didn't notice anything unusual in appearance, just a few minor text
related items (grammar and spelling).  Also, the "Top of Page" link on
the bottom of http://www.globalserve.net/~jval/isitart.htm was not
displaying (you had the color set as white on a white background).  A
couple of other little things, but the look and feel of the website is
nice!!

The thunbnail images were available from Jay's website to view for this
person, but the PARs never got included into the Contest Kit zip file. 
One of those images got a single vote though.

That's probably why no further postings have been seen from that email

The next line is where you are telling Fractint to find the formula, =
first by filename, then by formulaname within the file.  So.... you =
should be storing your par as bessels.par

This is where you went wrong. I cut and pasted this into files as you =

It is called GSpecial.par.  You sure it is not there?

I just downloaded http://www.geocities.com/CapeCanaveral/Lab/3825/Contestk.zip
It is there.

The copy that I last downloaded only had 48 PARs.  The GSpecial.par was
not in my Contest.zip file.  Maybe that was the last one added and I
downloaded before the final update.

But I do remember seeing the images on the Contest webpage along with
the PAR link for the email posting.  Others probably had a full version,
due to the fact of a vote being counted.

Oh well, that was way last year, too much time has gone by (and too many
parties).

Hi guys and gals,

Sorry to be-labor this, yes GS was near the last to post

The dates I have on my machine for these files are, sorted by date

So we have D M Jones (a repost but I don't think I saw the original), 
7 minutes after GS and these: J Oliver (repost), K Mitchell (repost), 
S Gallet (repost) after GS.

My ftp log shows this
97.12.06 00:13 B C:\jay\transfer\Contest\GSpecial.par --> home.san.rr.com
/Contest GSpecial.par

Finally, this file http://home.san.rr.com/jayrhill/Contest/CONTEST.ZIP
is dated 971206 08:21 according to ftp, and it contains the GS par file.

So, his material must have appeared about Dec 6.

BTW, I will make one more version of the Kit with image names 
under the images.  That should make it nicer. Then it can rest 
at Spanky at last.  So if there are any other remarks...please write.

Also, I would like to quote a few of the early postings by Nuke 
and a few others which were the spark to start the contest.  Any
objections?

At your service,
Jay

Dick, you write about separating the pars and the frms, and putting them
into appropriate directories. Please can you answer my question?
I am new to Fractint, but really keen to try to create some fractals from
the frms and pars other than the standard ones available in fractint. I
havae so far copied frms into fractint itself, and pars into a subdirectory
of fractint, but I have no idea how to pull them together to create an
image. I can call up the frm file, and then get a screen asking for
parameters. I don't know what to put into what box, and I thought there was
some way of entering an entire par file into fractint, but so far I can't
work it out. ANy words of wisdom will be much appreciated.

Subject: (fractint) The dreaded aaaaaa's again :(
Date: 06 Jan 1998 08:15:45 -0000

Back in the "(fractint) text editor" there was various discussion on how to
rid text files of the dreaded accented 'a'.

One suggestion was to download PFE, Which I did...

Having copied par text from outlook, pasted it into PFE saves out as a *.par
file.... it still has the a's when read by fractint!


Am I missing something with PFE, could whoever suggested (don't have the
posting anymore) PFE help me out.

Thanks Peter

I looked at the time of my Contest.zip file, it was downloaded on
12/05/97 at 20:18:00 CST.  But, if you had to put in others besides the
GS posting, why does mine contain all but that one PAR???

I know I must have grabbed the zip file early by a few hours, that's the
only explanation.

Anyway, I was also looking back on how the contest got started and found
this posting that was 14 hours before Nuke's:

        I agree. Why not use the famous 'Tim's_random'

You don't mention it: did you do any editing (a global search-&-replace,
perhaps?)

If you already have it saved as a par file, just drag the file's icon to
the PFE icon on your desktop (it's not there? For shame!). Bang: instant
opening! I like this!

...........(snipped stuff)............

If you peruse the many personal fractal galleries on the web, two
things become immediately apparent. Some fractal artists consistently
produce beautiful images while others are erratic. (I am not
speaking here of the simple personal likes or dislikes of the
viewer.) Also, despite the rather impersonal origins of the fractal
formula, a number of these artists have also developed their own
style which becomes recognizable with repeated viewings. It is not
that you can immediately identify the creator of a particular image.
Instead it is that, upon discovering the artist's identity, you think
"Yeah- that looks like something she'd do..." This certainly suggests
that there is more involved than cold calculation.

An interesting experiment would be to post a mundane formula
and have the readers of this list plug it into Fractint, work with
it in their normal fashion and then post the results. I predict that
each will be different but that many will be very similar- a strong
family resmblance, if you will. However, I also expect that some
will look so radically different that it would be difficult to
believe they share the same formula. In other words, art may be
calculating but it need not be mere calculation.

Hi Beth,  I'm also new to Fractint (and new to this list :-) ), but do know
that Fractint can read any par file you copy into it:

From the main menu, click on "run saved command set <@>" under File (or just
press "@").  This will take you to a directory list of par files. Navigate to
the subdirectory containing your par file. Then select a given par entry in
that par file and Fractint will draw the fractal.

When you start by calling up a frm file, you must enter parameters.  This is a
matter of trial and error - experiment until you get an interesting looking
image.  Then you can save the parameter settings for this image as a par file
by pressing "b".

I hope this helps!,

Mark

Well... You can't edit or search and replace the a's if you can't see them!
The whole point is that they are not visible in email or when pasted into
PFE.
They *are* visible when read by FractInt..

Hi Everyone,

            I have been reading the fractint mailing list (in digest form)
for a couple of days now and am going to perhaps nievely considering the
other work I have seen post my own par and formula file. Fractint IMHO is
one of the best programs I have ever used and the authors deserve much
credit especially considering they get no financial reward. The formula
below was created via a combination of luck and educated (well only to year
12 maths) guessing:

Copy following par entry to a par file:

tattered           { ;Copyright Ben Leighton 1998

  }


Copy following formula to ben.frm:

c7manderiv  { 
;Copyright Ben Leighton 1998
;try sin(fn1) and cos (fn2)
q=pixel, a=1, b=flip(1), last = 0:
a=a+ fn1(imag(pixel)*10*(1/imag(q)))
b=b+ fn2(real(pixel)*10*(1/real(q)))
q=(q-a-b)^2 + pixel  
(a+b) <= 300
}



                                                                        :) Ben

Hi Beth - I believe you are mixing apples and oranges here, probably because
the word parameter gets a little overworked.  The parameters asked for in the
screen you get when you call up a formula refer to replacable values written
into the formula (some formulas have no replaceable parameters).  Put anything
in there.  Some things will work some will not. Those of us with limited math
skills just use trial and error here and save the results from the lucky
shots.

To enter a particular image's parameter file ( these are files where all the
above choices and more have already been made and the resulting image saved.)
you press the @(or 2) key whenever you have an image ( such as the mandelbrot)
on the screen.  This will present you with fractint's default fractint.par
collection of images.  Pressing F6 at this point will let choose from among
whatever other .par collections you have acquired.  You then open the desired
collection, select the desired image, and press "enter".

Another point that can lead to some confusion (I believe someone else may have
mentioned this) is that a .frm file may contain many individual .frm entries
and a .par file may contain many .par entries

I hope this helps.  Good Luck and many happy hours Fractaling.

Subject: (fractint) Fractals on TV in Britain
Date: 06 Jan 1998 14:01:39 -0300 (BST)

Happy New Year to all!

Here in Britain we get a short series of science TV broadcasts every 
Christmas - the Royal Institution Christmas Lectures, for young 
people.  Last night, I just got round to watching my tape of the fourth
(out of five) of these, which was about Chaos.

The lecturer (yes, they are filmed as lectures in the RI Lecture 
Theatre) was Prof Ian Stewart, and he mentioned Mandelbrot sets, 
showed an animation of a Mandelbrot zoom, a Julia zoom and one other 
similar that he didn't name.  He also talked about Barnsley, referred 
to the Encarta IFS encoding, and tried to show how an IFS coding 
system might work (not terribly well, I thought).

There was also a 'manual' demo followed by a computer run of 
<somebody's> Ant, the one with rules [fwd 1][L or R according to 
colour of square][invert previous square].  This was quite well done.

These lectures get quite a good audience I believe, and though he 
didn't mention Fractint, the overall presentation was interesting and 
hopefully would encourage some younger viewers to investigate 
further.

I would also create a subdirectory for your frms and put them in
there.

Probably most of us don't know what to put in there. So we
just plug in different numbers, etc and see what happens-
often good things do. :) If the box needs a function rather
than a number just press the left or right arrow key to
cycle through the functions. I hope I understood your
question correctly.

>and I thought there was

Press the 2 or SHIFT-@ key on the top row of your keyboard.
This will let you load pars into fractint.

When fractint runs a par that requires an external formula, fractint
looks wherever you stored your formulae and reads everything
there until it finds (or doesn't) the formula it needs. But if
you set up a par subdirectory as recommended, you have to tell
fractint you did this. You tell fractint by creating an
SSTOOLS.INI file. This is just a text file that fractint
will read when it starts up. My SSTOOLS.INI looks like
this:

[fractint]
TEMPDIR=c:\windows\temp
WORKDIR=c:\fractint
PARMFILE=c:\fractint\parms\jaxdev.par <--- a default par file (optional)
                                           the important part is
                                           c:\fractint\parms where I keep pars
MAP=c:\fractint\maps                  <--- where I keep colour maps

Of course, your SSTOOLS.INI should *not* include all my comments
that start with <--- and it should be in the same directory
as fractint.

All this information is included in the Fractint help but it
can be very difficult to find when you are just starting.
Fractint is great but not very friendly by today's standards.
It seems to be written by programmers for programmers.

I hope this helps.

Not sure. We were thinking of buying a plane but decided on
a sailboat instead. So that makes JM about 10 years old. MJ is
perhaps 5 years old. Even though M and I are former
photographers we have almost no pix of each other. I used
what we had because a member of this list (who shall remain
nameless) insisted that we must have pictures of ourselves
displayed. Her contention was that only females did this
because men lacked the courage :)

At any rate, M and I are both grayer now. M went first but
I only turned gray because I thought it was the polite thing
to do. We just got a digital camera (still not used though)
so some-day-real-soon-now we'll display more recent
photos. I think you will find our pages will then become
more, shall we say, mature... I'm 50 and M has her usual
10% up on me.

Yep. That was the start. So how would you judge my predictions?

I went on to set up my But is it Art page and Name the Artist
pages but the responses to them have been pretty minimal. Not
enough interest I suppose... sigh. I think they will be the
last of my group experiments. Too bad really because I have some
interesting questions I would like to have explored that would

without a large enough participation sample there is no useful

Sometimes I'm not sure if the comments exist for the

Yes. I hate flash just for the sake of flash. I actually

Jack....

I enjoyed the Name the Artist pages......no reason not to leave them up for
a while if you have the space.

For our next contest....someone ought to write a  little program that
allows the computer to randomly generate fractals and apply colors.....say
for a couple of days.....and save them.....and also "selects" 3 images to
submit to the contest. Part of the fun could be guessing "who" the computer
is....what do you think??? If most of us guess right....I think that would
be very indicative that fractals are more than just math.  BTW...my
computer scientist son was babbling about a mathematical proof that
computers are limited....can't remember quite how...but we were discussing
the fractal art conundrum.

Now, the rookie speaks:

I think you've opened up a tasty can of worms, and let me be one of 
the first to gobble a few...

Although I am not a degreed CS type (I have a physics BS), I have 
my own take on the topic.  

Computers are limited, as are we humans, by their wiring and 
programming.  Digital computers are designed for crunching numbers.  
Making them do more requires analog interfaces to the outside world 
(i.e. video (cards, monitors, cameras, scanners), audio (cards (as 
always), mic's, speakers), tactile (keyboards, mice)) analogous to our 
senses (of course, systems to replicate taste and smell also exist, but 
most of us have no reason to provide our computer with those capabilities).  
Our brains, on the other hand, have been designed by billions of years of 
biological evolution to drive a number of complex behaviors necessary 
for survival, and our sense of aesthetics has been affected by *at least*
ten thousand years of cultural evolution. 

In spite of computers' limitations, they really lack only two layers of
capability: 1) a neural net to replicate retinal and visual cortex circuitry, 
and 2) software to develop, categorize, store, access, and update style 
and preference data.  Similar efforts to optimize computing for specific 
tasks have proven successful to various degrees (i.e. "Deep Blue" 
(chess), the CAM projects (Cellular Automata Machine), Digital Orreries 
(high-precision, high speed orbit propagators), optical target tracking, 
prime number crackers, and walking robots with controls based on insect 
nervous systems), and I suspect the same could be done for fractal art. 
The problem is that to do it right would take big bucks and mental effort 
worthy of a PhD (or several). 

For now, I suspect you would be disappointed with the results of a 
"pure" computer generated effort (on the other hand, some of you
might be able to blow our socks off; life is full of surprises!).  However, 
allowing human intervention at one or more points in the process could 
make the contest a whole lot more do-able.  These might include: 

1) Provide, in addition to Fractint's default random palette capability, 
 a dozen or so favorite palettes to select from.

2) Leave selection of the final submissions to a person.  What computers
 lack in creativity they make up for in their ability to tirelessly crank out 
 variations.

Anyway, it's an interesting idea!


Hope I didn't bore y'all, Bud

   It is provable that the problem-solving ability, meaning the ability 
to answer a given question, of any computer is equivalent to that of what 
is called a Turing machine. It is fairly easy to also prove that there 
are problems which, despite having quite definite solutions, cannot be 
solved by a Turing machine and thus any computer. This, and related 
discoveries of early-twentieth-century mathematics like Godel's theorem, 
are probably what your son is referring to... Note that from a scientific 
standpoint, the term "computer" as used here includes a computer like the 
human brain.
   Note also that the determination of what problems are and are not 
solvable is often a tricky task that people spend whole careers on...

If this doesn't make any sense to you it might be because I

Oh, I forgot another obvious example, in light of recent developments:
music!  I think if we were to ask someone in *that* field, we might get 
more optimistic and perhaps helpful input.

No, it doesn't.  The human brain is not a Turing machine in any shape or 
form, and does not work algorithmically.  Hence there are propositions 
(Godel's theorem being the first example) which we humans can see as 
"obvious" (or least mathematicians can!), but are provably impossible for a 
computer to "understand".

Many people may think this is heresy, but I think it would be preferable to

It might even be possible for the mail server to automatically gather up

   er... not sure I know what you mean by "see as 'obvious'" or 
"'understand'" here. I don't know how to discuss what a computer does or 
does not "understand". A computer, however, can certainly re-create the 
proof of Godel's theorem by following the same logical steps.
   
   To clarify my previous statement, which is admittedly controversial as 
stated: From the standpoint of theoretical computer-science modeling of 
computing, no aspect of the human brain which has been found 
scientifically describable, appears to be exempt from the models of 
automata theory which leads to the proofs about Turing machines. This 
does not suggest that we understand processes of thought or that emergent 
properties cannot exist; but assuming that all functions of the brain do 
in fact ultimately depend on the physical nature of the brain, all 
its low-level physical or chemical processes can indeed be modeled as 
automata, and the proofs do thus apply.

   It is entirely possible to disagree with this statement on religious 
or mystical grounds and I freely accept that our scientific knowledge of 
the brain is as yet quite insufficient to describe it fully; however, to 
the extent to which we can describe it, this appears quite clear.

This is going to cause more problems than it solves.

It requires attachments, which have already been voted down.
It adds two extra layers of encoding, making two extra places where
    things can go wrong (zip + uue)
Uuencode is less portable than base64 encoding, upon which MIME is
    based.
Since uuencode (and base64) expands source material by 1/3rd, its not
    clear that anything would be gained by taking a text file and
    compressing it and then expanding it again.
All PAR/FRM/IFS/etc. files are text files -- treating them as binary
    attachments makes them unavailable to text search engines that
    search through the list archives.

In summary... just deal with the plain text files.  There will always
be problems with embedded text files, all of which are solved by the
use of MIME (an existing standard).  However, until the majority of
people (or at least the ones who complain about MIME) get MIME
compliant software, I don't see MIME approaches being accepted.

I found that section of your website interesting.  The easist images to
recognize were from Earl Hinrichs (almost instantly) and Linda Allison.

But this was a "trick" question:  twelve images shown, nine artists
listed in the side bar, two listed in the fine print (at the bottom),
and one unlisted unknown.  Not exactly a one for one match.

P.N.L.

I keep seeing this problem about Paul getting his messages bounced
back.  I haven't seen what address he's posting to -- he should post to
fractint@lists.xmission.com, NOT fractint@xmission.com since
lists.xmission.com now handles all list traffic for xmission and list
mail sent to any other machine will bounce.

If Paul is using that address, but still having problems with the
messages being bounced, he should forward one of the bounced messages
WITH ALL HEADERS INTACT to Tim Wegner <twegner@phoenix.net>, list
administrator.

With a sample bounce, Tim can work with the folks at xmission to sort
out the problem.

Subject: Re: (fractint) Happy New Year!
Date: 06 Jan 1998 16:35:13 -0500

Beth,

   I'm sorry you're having so much trouble recreating the images posted
here as parameter entries. One side effect of the center of gravity of
Fractint discussion moving from the CompuServe forum to this message list
is that a majority of new images are now posted as part of messages rather
than in the traditional .par and related files. Getting from a message to
an image drawing on your screen does take a fair amount of knowledge of how
Fractint works. I'll try a step by step explanation of how to do it; I hope
it solves your problems for you. If not, let me know, and we'll keep at it.

   First, make sure you have the most recent version of Fractint, currently
19.6. Each new release incorporates new features, and many current postings
will only work with the latest version.

   Second, a word about directories. Unless you give instructions to
Fractint to the contrary (via special command line options or in a file
called "sstools.ini"), Fractint will look for all relevant files in the
same directory where Fractint.exe is located. Starting off, it is probably
easiest simply to use the one directory. As you get more familiar with the
program, you will learn how to create separate subdirectories for the
various kinds of files, and how to tell Fractint where those subdirectories
are.

   Finally, the information which Fractint uses to draw an image is
contained in entries with the form:

Name  {; comments
  various commands
}

The relevant entries are

   1. Parameter entries. These are entries with commands such as type=xxx
colors=lots_of_Martian, etc. Usually, the first command is "reset=####",
where the #### is the version of fractint which was in use when the entry
was created. Don't worry about that; if a version earlier than 19.6 was
used, the current version will still draw the image.

      Parameter entries contain all the information needed for fractint to
draw an image, unless "type=formula", in which case fractint will need to
find the formula. The name of the formula is identified in the entry with
the command "formulaname=xxx". There is also usually a command in the
parameter entry "formulafile=xxx.frm", but this is not important, because
Fractint is quite clever in searching for and finding formulas. More about
that later. "type=ifs" and "type=lsystem" also require fractint to find the
relevant ifs or lsystem entries, but postings with these commands are
reletively rare, so I wouldn't worry about that now.

     Parameter entries should be copied to a file with the extension
".par". You can use any name you want for the file, such as 1998msg.par.
Just copy the text of the message to the .par file, and then edit it to
delete everything except the parameter entry or entries contained in the
message (in each case beginning with the name of the entry and ending with
the "}"). The .par file should be in your Fractint directory, as I
discussed above, unless you have explicitly specified a different
directory. Don't delete the original message if there are formulas in the
message! Those entries will be copied to a separate file.

   Occasionally, problems are caused by the email software which people use
to post these entries. Take a look at each entry; there should be no blank
lines, and for the long commands such as colors=, the last character of the
intermediate lines should be a "\".

   2. Formula entries.  When the parameter entry is "type=formula",
fractint must find the named formula in order to draw the image. A formula
has the same overall structure as a parameter entry, i.e.

Name {; comments
  various calculation instructions
}

and are pretty easy to identify; they have assignment instructions such as 
z=pixel or c=sin(pixel); a ":" will appear somewhere in the formula; and in
some you will see flow control instructions such as IF (x==y) etc.

   Formulas need to be copied to a file with the extension ".frm". Any name
is OK, such as "1998msg.frm". The file should be in your fractint directory
as discussed above unless you have explicitly specified a different
directory as a command line option or in sstools.ini. Edit the file to
delete everything except the formula entry or entries. If an entry name is
preceded with "frm:", delete the "frm:". This is a feature which permits
the formula to be included in a .par file, but it is a good habit, I think,
to get the formulas into files with the .frm extension. That way they will
be available for general use and not just the initial drawing of the
related parameter entry.


   3. Ifs and Lsystem entries. The general format is the same, but the
information in these entries looks quite a bit different. They should be
copied to files with extensions ".ifs" and ".L" respectively, and any
preceding "ifs:" or "lsys:" edited out.


Now, to run the parameter entry.

   1. Go to your fractint directory and start Fractint.
   2. Select your video mode.
   3. Hit Shift-2 (the "@" key). This will probably bring up a list of
parameter entries in the default .par file "fractint.par".
   4. Hit F6. This exits fractint.par and shows you a list of .par files in
the default directory. Presumably, your 1998msg.par will be one of them.
Put the cursor on it, and hit <CR>. This will show you a list of the
parameter entries in that .par file.
   5. Move the cursor to the entry you want to draw, and hit <CR>. 
   6. The image should start drawing. Enjoy.
   7. You can zoom, change parameters, and do anything else that fractint
permits you to do with an image. Important commands to do these things are
Page-UP (for zooming), and "x", "y", and "z" for changing various options.
You can save the image by hitting "s". You  can create your own parameter
entry by hitting "b" and entering the requested information.
        

Finally, if you want to draw your own image using a formula, hit "t" from
any image screen or the main menu, select type "formula", and hit F6 to get
out of the default fractint.frm list of formulas to see a list of .frm
files. Select the file you are interested in, hit <CR>, and select the
formula you want to draw. Before drawing the formula, Fractint will show

variables (p1, p2, and p3) and user specified functions (fn1, fn2, fn3, and

Beth:

Mark and George answered your question quite well.  There is one concept that
may not have come through clearly:

A named par file consists of parameter sets for a number of named Fractint
images.  During December, 1997, for example, there were a whole bunch of sets
of image parameters that were included in messages from the various subscribers
to this list.  I selected and copied them all, one by one, into a single par
file that I just called Dec97.par.  George described how to use <2> or <@> and
<F6> to get to the par file, then arrow up or down to the image you want.

Essentially the same scheme applies to formula files.  A named frm file may
contain many individually named formulas.  I placed last month's formulas, for
the most part, in Dec97.frm, for example.  In a couple cases the message
contained a full file of formulas that I saved under the name used by the
sender.  Again, George described how to start with <t> to get to any individual
formula file you want.

Of course, if you want to generate a particular image, the formula called for
by that image must be present somewhere in the Fractint directory.

Since you are new to Fractint, maybe you are not aware that par and frm files
are ASCII text files.  You can examine how they are put together by using a
text editor or your word processor in .txt mode -- just open the name.par or
name.frm as you would any other document and look it over.  In fact, you can
use your editor to make changes directly in the par parameters or in the frm
files -- and that is what you have to do if the color  or other parameters are
garbled as George mentioned.

I think your best bet might be to play around some more with the 'standard'
formula and parameter files that come along with Fractint and not worry about
downloading and implementing the ones in these messages until you have the
'standards' mastered.

Dick

Help!
I've been enjoying generating lots of the wonderful fractals posted on
the list, especially the fantastic 3Dballs series with variations. This
all came to an abrupt end when I downloaded somebody's files infected
with the dreaded "=3D" disease. Full of confidence, I found and replaced
all of these, and now none of the ball fractals work either! Guess I
must have stripped out too many 3D's.
Can any kind soul send me directly all the ball-related par and frm

This question is one I have wondered if fractals might be a good application for
(what a horrible sentence that was, eh?)... E.F. Schumaker (a philosopher)
points out that there are basically two types of problems, convergent and
divergent.  For a convergent problem, many starting solutions can be refined
into a single, optimum solution.  I think the evolution of the bicycle is the
example he gives for this... a divergent problem, on the other hand, has two (or
more?) optimum solutions, and which solution is the right one becomes a matter
of intrinsic or personal values. Ask any statistician and she will tell you that
values are too flighty to be modelled - enter fractals.  Or at least, that's the
idea.

Asleep yet?  :)   Jason

Here's my hunch: recent progress in the field of quantum physics has revealed
that information can travel faster than the speed of light between two particles
that once interacted.  This phenomenon has been experimentally proven (1).  What
if our brains make use of this phenomenon, and are able to receive information
in a similar manner?  The experiment in which information was shown to travel
faster than light doesn't dare to suggest a *medium* for the transfer, but what
if our brains can access this medium?  If this could be proven, it might shed
light on all manner of 'otherworldly' phenomena (I'm especially interested in
the contagiousness of yawns... :)  To be sure, I'm below novice status when it
comes to these topics, but what I've read doesn't seem to negate the
possibility.  And of course, fractals will come into play at some point...

Put that in your snipe and poke it!  Wonder, Jason

I'm sorry about that and certainly didn't intend any "trick". I
didn't include Margaret's or my name in the side bar list
because we don't view ourselves in the same league. But I did
include our names at the bottom of the pics where I assumed
everyone would find them and understand that our images were
included. Perhaps this assumption was incorrect. The 12th
pic by Ann Onimusse was supposed to be a joke (the name
should have been a clue). It backfired as I got a lot of email
asking who Ann was.

I was curious to see how many would attempt, via email, to
guess her identity. The only one who did was Sylvie Gallet
and she was pretty damned close! In my defence, I would say
that police suspect lines-up often include a ringer. I don't
think this was really cheating, just a surprise twist for a
minor added complication. After all, conceptually the guess
procedure was not compromised. But if others also think this
was a cheat say so and I'll remove Ann Onimusse.

This helps enormously!!!!! I modified my sstools.ini file with GREAT
trepidation based on the ......ahem.....help .....provided at the fractint
site.  Your explanation is MUCH more complete and it is my suggestion that
Noel incorporate it into the fractint documentation dealing with
sstools.ini.   One very basic thing that was NOT explained is that one gets
sstools2.ini in the fractint package.....and to be useful the file needs to
be re-named after the desired changes are made.  I think everyone has done
a marvelous job with the documentation for fractint.....but that questions
like Beth's point out where additions need to be made .......we all have a
knowledge base we tend to forget about when trying to explain something and
that inhibits the transfer of information to anyone who is not at our level
in a particular area.

WE INTERRUPT WITH THIS SPECIAL WARNING: 

It has recently come to my attention that Pandora,
my computer, has subscribed to this list under my name and
without my knowledge or consent. Any comments from her
with which you agree she probably overheard from me. The
rest were undoubtably her own opinions. She is also
claiming we could not produce our fractals without her!

Paul....

thank you so much for another marvelous formula.  I have a question
regardring the color mapping...it is unusual in that it is not smoothed
from color to color...but it fits perfectly with the image.

This leads me to guess that here is some sort of mathematical relationship
between the colors and the formula...am I right??? or did you get tha
perfect color set just by hard hit and miss work???  It was truly
lovely...and I am looking forward to messing around with the formula

Angela

ps...you can email me directly at wizzle@cci-internet.com and I can post
your reply

Peter: I found myself in the same boat. I did a little research and =

value of 160.=20

How do you get that? Well, you start with the Num Lock on. Then press =
the Alt key and hold it down. While holding down the Alt key, key in 160 =
on the *number* pad (not the keyboard). When you let up the Alt key, =
viola, you get an accented a like this =E1.=20

This doesn't work in PFE (as previously suggested) or Notepad or =
Wordpad, but it does work in my old DOS text editor. I can see the =
accented a's and I can do a "search and replace" and clean out the file =
just as slick as you please. Give it a try and let me know how it works.

I'd be delighted to add any improved docs to Fractint. In fact I'd 
encourage folks to submit improvements. Remember, Fractint is a group 
project. Helping with docs is a way non-programmers can participate.

One little know secret is that with the help compiler hc.exe that 
comes with the Fractint source code, anyone can edit the help source 
files and add them to Fractint, as long as the hypertext links are 
not changed. I'd be willing to post the hc.exe file if anyone wants 
to try this.

I'm asleep at the switch, so if someone (preferably Jack, since he 
is the author) could email me the improved sstools explanation, I'd 
appreciate it.

Personally, subtleties are lost on me, not to mention hints.

I would have listed the name as a choice, and spelled it more like Ann
Nonimus or Naim Less.

Ah, that doesn't sound like a PFE problem - at least I know of no possible
cause.

Perhaps if you email me the offending file, I could have a bash at making
sense of what's going on. In the meantime, you might try TYPEing it in a
DOS window and seeing if they show up there.

You know, I'm starting to get the feeling I'm missing some of the traffic
on this list... I'll look in the archive, but why would I be missing them?

Ah, now I'm sure of it! _Accented lowercase a characters_, yes? &aacute; in
ISO entity name lingo!

The thing is, Fractint is reading ASCII 160 as an &aacute; - as this is the
code (MS-) DOS assigns the character, while in Truetype (invented by Apple,
remember) and most other fonts used by Windows, including PFE and clearly
whatever your email software uses, ASCII 160 refers to a nonbreaking space.
So that's why you can't see it. So try searching with PFE for "ALT+0160"
and see if that catches what look like spaces in the locations where a's
are turning up in Fractint. To confirm, you can change PFE's screen font
("options>preferences->screen font") to "Terminal" to use a DOS-type font.

   er... not sure I know what you mean by "see as 'obvious'" or
"'understand'" here. I don't know how to discuss what a computer does or
does not "understand". A computer, however, can certainly re-create the
proof of Godel's theorem by following the same logical steps.

My understanding was that it could not.  That is the whole point of Godel's 
theorem.

   To clarify my previous statement, which is admittedly controversial as
stated: From the standpoint of theoretical computer-science modeling of
computing, no aspect of the human brain which has been found
scientifically describable, appears to be exempt from the models of
automata theory which leads to the proofs about Turing machines. This
does not suggest that we understand processes of thought or that emergent
properties cannot exist; but assuming that all functions of the brain do
in fact ultimately depend on the physical nature of the brain, all
its low-level physical or chemical processes can indeed be modeled as
automata, and the proofs do thus apply.

This assumes that physical laws are deterministic and algorithmic...

I'm afraid I'm not an expert on this topic, but I refer you to two books by 
Roger Penrose, "The Emperor's New Mind", and "Shadows Of The Mind", which 
explain all this quite well.

Err? I always get suspicious of philosophers (or philosopher-scientists)
who try to take mathematical or physical concepts out of their home
domain and apply them willy-nilly. So often rigour is sacrificed in
favour of a nifty metaphor or convenient analogy.

The Turing machine proof? Is this the Godelian proof that Roger Penrose
concocted? If it is, then what's the other one (respond privately if you
wish)? I'm familiar with the proof I mentioned, and never _quite_ been
convinced by it.

Not proven. Not enough is known about the human brain to confirm whether
it is a Turing machine or not. It can simulate a Turing machine and do
everything a Turing machine can do, but it is not proven that it can do
anything more. The Penrose objection mentioned above (the best anti AI
argument I am aware of) is, as Penrose himself admits, not rigorous and
crucial points are covered with handwaving.


In my opinion, the whole question is moot. It's quite clear that minds
are _physically_ possible (everyone is their own best existence proof).
So what if it turns out that our notion of computability is insufficent?
It's only our notion and we're quite capable of extending it if and when
it turns out to be needed.

This topic comes at an apposite time for me, as I'm currently attending
a conference on unconventional models of computation. Mainly quantum and
DNA models - formal abstractions, implementations, possible
applications, their prospects for exponential speedup of problem-
solving, etc. Reversible logic and cellular automata are also highly
featured. There are considerations on the possible noncomputable
capabilities of some quantum approaches, but since there is no
noncomputable behaviour in present-day quantum mechanics (and hence none
in the rest of physics - hence chemistry hence biology hence brain
function) "computability" for the most part retains its "classical"
sense of "something that can be done on a Turing machine" (though there
is one paper that has yet to be presented titled "Even Turing machines
can compute noncomputable functions").

I regard intelligent, conscious and aesthetically sensitve machines as
inevitable. Eventually. Not yet. My running(!) copy of Windows 95 takes
159MB on disk (though it has no excuse being that large for what it
does), and that is still some way from the 3GB of the human genome
(though I'm sure  Monopolysoft is working on more bugware to force down
our throats!) The largest software application I know of still fits in
executable form on a single 680MB CD-ROM. On the other hand it has been
estimated that memory on the order of 10TB would be needed for storing
a human mind, and probably quite a bit more in an executable form. But
how long ago was it that Bill Gates was saying that noone would ever
need more than 640kB?

I take on the penalty of an off-topic post. If you want to discuss this
with me privately I would be happy to do so.

Absolutely correct Morgan :)

I can now use PFE to edit the little blighters out!

hmmm... If lots of us have this problem... Maybe Tim will consider making
FractInt compensate for ASCII 160?

Anyway, Morgan thanks for the workaround, much appreciated

Subject: (fractint) Client-server Fractint
Date: 07 Jan 1998 15:52:21 -0000

I was thinking about the forthcoming rewrite of Fractint for version 20, 
and wondered: why not use a client-server model for fractal drawing?

The client sends a message to the server, saying "here is the formula to 
use, please give me the value of the pixels in the rectangle (0,0) to 
(100,100)", and the server sends back the pixels.

The advantage of this would be that it would be easy to add distributed 
fractal drawing to Fractint, as well as an easy way to use the full power 
of multiprocessor boxes (by running several server processes on the same 
machine).  I don't know if any of you have seen the program MandelSpawn 
which works on this model.  You can get _very_ fast fractal drawing if you 
have a whole network of machines at your disposal 8-) .

It could even work over the Net.  Suppose a two people who read 
fractint-digest decide to cooperate.  They both run the fractint server on 
their machine, and when running the client, they can get the other person's 
machine to draw half of the image and send it back over the Net - and 
instantly, you get twice the speed! Of course, this wouldn't be useful if 
they were both using their machines at full pelt all the time, but the 
typical PC is idle for 90% of the time - time that could be used 
calculating fractals.

What do you all think?

Subject: (fractint) another frm and par
Date: 07 Jan 1998 09:11:11 -0700 (MST)

I came up with this formula file while playing with the "bubbles" coloring
method.  The idea is to specify a small range, say 98% to 102% of the
magnitude of c, and to color the pixel (white, say) if the iterate ever
falls within that range, black otherwise.  It creates a graceful series of
loops that get more and more convoluted, showing the fractal shape in
overview.  It seems to work with other formulas, not just z^2+c.  If you
use this, you'll definitely need to use single-pass mode, and will
probably want to anti-alias down from a much larger image to your final
piece.  I will post an image (infinity) done with this formula to the
fractal pictures newsgroup.

frm:minmaxc_jul { ; Kerry Mitchell
	; colors the screen one color if the iterate falls between the
	; high and low bounds, otherwise leaves it blank
	; Julia set--c=p1, bailout=real(p2)

Peter,

 - I found myself in the same boat. I did a little research and found out
 - that the forward slash accented a is defined as ASCII decimal value of
 - 160. 

Congratulations, you've just discovered the extra space character in the
Windows character set (which is different from the DOS character set).  For
example, in Windows, the forward accented a is code 225.

Incidentally, any web page using a non-breaking space will generate code
160 in a Windows browser, and if you copy/paste in another app, you get
this.  If you want to search/replace non-breaking spaces in a Windows text
editor, enter ASCII code 160 (in the method you describe) into the "find"
portion of the dialog.  I use TextPad rather than PFE (personal preference)
and this works fine for me.

Hi Sylvie,

I get everyone's post just fine. It is, as discussed at length on this list
a combination of certain folks email sender and others email reader.
I use Micro$oft Internet Mail on Windows 95. No problems. 
Apparently my posts are readable to all and I can read everyone's 
posts.

So I was befuddled, bemused and befumed when 
I saw the archive is one of the clueless email readers. 
Look at Lee Skinners post  (messed up),  Jay Hill's (fine) 
and Morgan L. Owens (fine)  here
http://www.xmission.com/pub/lists/fractint/archive/v01.n064
and Sylvie's (messed up) and Peter Jakubowicz (fine) here
http://www.xmission.com/pub/lists/fractint/archive/v01.n063
and again Sylvie's (messed up) at 
http://www.xmission.com/pub/lists/fractint/archive/v01.n061
Watch the archive for this post. It will show the May-2 formula 
just fine but Sylvie's original will be screwed up.

We need an archive free of 3D effects! That is why I posted Paul's 
formula on my page, 34k for just his.  (I hope my late last night 
silliness was decryptable  :-)  , there were illustrations to go with 
the text.)

A complete 1997 collection must be pushing a megabyte 
for just the frm + par. A weekly collection posted somewhere 
would be useful. Someone mentioned it already, as an 
automatic server thing. But if such is another UNIX dummy 
collecting =3D effects, forget it!  If someone has a 1997 (& 1996)
collection very well organized (and I'm not sure exactly what 
that means) that would be useful. And now would be a 
good time to start 1998 :-).

Isn't the Windows character set the same as ISO Latin 1?
See <URL: http://www.htmlhelp.com/reference/charset/>, which gives the
same characters for the different code 160 and 225 as you describe.

Most likely.  But "ISO Latin 1" doesn't mean much to most people.
"Windows" does. :)

There are several client-server distributed M-set programs out there,
I can dig up references.  Portability is a real problem, although its
significantly easier now that winsock has become popularized on
Windows.  However, that still leaves a socket implementation for DOS.
The technology is there, but interoperability and portability of code
is a problem for fractint's limited operating environment as a 16-bit
dos app.

Hi Sylvie,

Not on my system (CompuServe), but you can bet the archive of your post
will be scrambled!

I asked Compuserve if there was a way of switching the quoted-printable
encoding off (as you know, it affects my outgoing posts too). After sever=

Ed....

This is what I think of as the nice to have eventually category. I'm far
more interested in getting a winfract that....

1. does everything the dos version does
2.  has complete documentation and a dummy proof help utility
3.  runs under nt
4. preserves all the color mapping options I have in fractint and maybe
adds some anti-aliasing post processing or something....
5.  gives me a bunch more filters or formulas or whatever you think is the
proper term for coloring the inside and outside of the fractal (like damien
jone's stuff)
6. an expanded pallet would be nice.....but I'm not sure I'm crazy about
any of the truecolor programs.....and I hate their color control
interfaces.....so there's a problem for you all to solve.

If I can process the fractal as a background application while reading my
email or whatever, I don't really care that my processing time goes from 10
minutes to 5. And by next year I'll cut that time anyway by going from my
100mhz pent to 233 or something anyway.

Paul...you bring to mind some comments that I would very much like to see
in all formulas.......first, a hint about what values to put in when
prompted.  It is very frustrating to look at a formula with 6 blank spaces
and not have any combination of numbers work after 30 minutes.  Also, if a
formula requires some sort of resent in the basic or other options, that is
VERY handy knowledge to have.  This morning I was messing with a formula
that needed the decomp thingy (in the basic section) to be set to
256....like NO WAY am I going to know to do that. Having the pars is a
great help....but having that type of info in the formula itself saves
having to hunt for the par or gif that starts you out on the right foot.

Subject: (fractint) Ideas for future versions of fractint
Date: 08 Jan 1998 12:42:06 -0000

Here are some ideas I've had for the next versions of fractint. Some
or all of these ideas might be impractical or impossible, so don't
shoot me down with flames if I'm spouting rubbish.


Previous versions of fractint have generated fractals by using
several layers of program. These are the layers for escape time
fractals:
  1) Drawing mode algorithm (solid guess, boundary trace, 1-pass,
     etc.) - this gives a screen pixel
  2) Zooming and panning (also rotation, stretching and skewing) -
     this transforms the screen pixel into a point in the complex
     plane.
  3) Non-linear transformations (i.e. inversion) - this transforms
     that complex number into another one, which is used as the
     starting point for...
  4) The iterated function - the outputs of which are:
       the iteration count
       what caused the calculation to stop (maxiter reached, bailout
       reached, or periodicity check kicked in)
       the last value of z
     These are used in...
  5) The colouring algorithm, i.e. the inside=, outside=, decomp=,
     biomorph=... options. This gives a number 0...255, which is
     used to dereference the...
  6) Colour map - which is used to colour the pixel specified by the
     drawing algorithm (this is done by the hardware).

The next versions of fractint should follow the same plan, but the
addition of truecolour modes means that colouring needs to be done a
little more inventively.

Rather than have (5) output a single integer, it should output a
real number. This can be used to look up the colour in a colour map
which, rather than consisting of discrete list of colours, consists
of a short program which accepts a single real number and outputs
three real numbers (red, green and blue). For example, if all three
outputs were set to be the same as the input, you would get a smooth
transition between black and white. Of course, old fashioned maps
would still be supported, but there should be an option to make the
transition between adjacent colours in the map smooth, so it can be
used for continuous potential images. This way, assuming that the
screen can be redrawn fast enough truecolour images can be colour
cycled.

Better still, some colouring algorithms might output several real
numbers, each of which can be assigned a different colour map. These
could be colour cycled seperately, with different speeds and
directions. Then you also need an algorithm to specify how to
combine the outputs from the colour maps. For more information on
this technique, have a look at the amazing program "Chromazone for
windows" (written entirely in assember). It isn't a fractal program
(at least the version I have isn't) but it does have a fantastic
colouring facility.


Similar layering can be worked out for orbit fractals, .IFS and
Lsystem - the main difference is that (2) and (3) are done
backwards, and in reverse order (an ordered pair of real numbers are
used to work out a screen pixel).

For some fractals, e.g. bifurcations, you need to do (2) and (3)
both forwards and backwards, because you scan along the screen but
plot vertically.

Diffusion fractals and any other odd ones do their own thing.


Now, this is a Windows 95 program, which means
a) We can have images at any size - full screen mode or window mode.
   For window mode we need to specify the size of the window. For
   both modes we need an option to specify how many pixels are
   calculated for each screen pixel. No need for disk-video modes
   (the image must be stored in memory anyway, in case the window is
   hidden) - for images larger than the screen, you can view the
   image at half size, say, as a "preview" for what the "disk-video
   mode" is doing (of course, windows handles whether memory or swap
   file is used for this). I hope this makes sense.
b) Printing is much neater using the windows printing engine. A
   "print preview" should be implemented which supports scaling and
   centering (see the equivalent feature on Paint Shop Pro).
   (The print option in the DOS version of fractint, if it is to
   continue (and it should) might as well be taken out, and maybe
   put into another program. I'm sure there are much better
   dedicated programs for printing .GIF files.)
c) Background fractals: fractint can take over all the idle cycles,
   thus making background fractals without slowing down your
   computer (much).
d) Screensaver. If background fractals are enabled, presumably this
   would simply show the fractal currently being drawn. If no
   fractals are being drawn, it could just display a (colour cycled)
   slideshow of saved images.
e) Output file format: you can have as many as you like using output
   format filters. Ditto input format filters.
f) Mouse controlled 3D rotation to set parameters for setting 3D
   parameters.

For background fractals, it would be useful to be able to have a
"batch list" which you can add your pars to so it can calculate all
the images, one after another. You should be able to promote or
demote images within this list, and maybe keep multiple lists.

Fractint should have a built in editor for .PAR, .FRM, .L, .IFS and
.MAP files (especially with the new, complicated colour maps), plus
any other new similar filetypes. Also features to help organize
these files, such as having a hierarchy of "subdirectories" inside
.PAR files, which can contain other images and subdirectories, etc.

Email-ready output: output a .PAR file which contains all the
information needed to generate the image - colour maps, formulae,
everything. That suggestion will be popular with this list.

When reading such an email-ready file back into fractint, the
necessary bits and pieces can be seperated out and put in the right
places in the hierarchy, thus eliminating wasted disk space if the
reciever already has the right bits.


Drawing mode algorithms. Instead of having 1-pass, 2-pass, solid
guess seperately, you could have a single "n-pass" mode where you
specify "n" and an option to "calculate all pixels" or not. A new
algorithm could be to calculate the pixel which is furthest away
from all the other pixels already calculated. This isn't as hard as
it sounds, and would give a quick preview of the image. It could
also be adapted to be an improvement on the solid guessing
algorithm.

Maybe there could be an option to recalculate pixels where it looks
like the guessing algorithm has guessed wrong, like a paint program
(just wave your mouse over the pixels you want to recalculate).


More options and user defined options for stage (3) above. Currently
fractint only has inversion. Maybe this could be extended to
twisting, z+1/z transformation... How about the equivalent of a
"zoom box" for these (of course, for inversion, it would be what is
outside the box that is actually drawn, rather than inside).

Put built in types on the same level as formulas. It seems that most
fractals on this mailing list are of type=formula. You should be
able to write type=<formulaname>.

Lots more colouring algorithms, including field lines (which I think
has been cracked now - the thread on field lines, decomposition and
texture mapped fractals can be read at
"http://homepages.enterprise.net/berrypark/andrew/field.txt".
I gather these lines are at right angles to the isolines of the
continuous potential colouring (which is not be the same as the
electrical potential if the inside of the set contains uniformly
distributed electric charge, something else altogether). If so,
using these and cont-pot you can do all sorts of exciting
colourings, including texture maps.

User defined colouring algorithms, to make .FRM files simpler (at 
the moment we seem to have .FRMs for iteration formulas, .FRMs 
for colouring algorithms and .FRMs for each possible combination.

User defined bailout conditions.

Now, if (the most significant bits of) the output from (5) is stored
rather than the colour, you can change colour maps without
recalculating. Better still, if you store the output from (4), you
can change the colouring algorithm without recalculation, although
this could be impractical because of the amount of data that needs
to be stored, especially if you start storing lots of values of "z"
rather than just the last one. Store a flag for each pixel saying
whether it has been calculated or not, and you can switch drawing
modes without starting all over again.

Symmetry could be smarter - currently switching on decomp switches
off symmetry. Is this really necessary?

Higher level functions - it would be nice if some of these could be
built into fractint, but if not it would also be nice if user
defined functions could be written and used in "fn" types as well as
formulae (and even new colouring, colour map, bailout algorithms).

Algorithms for working out the optimum values of bailout and
maxiter?


Wow, this file worked out to be a lot longer than I thought it would
be, and fractint is already a fantastic program. Sorry I've been
lurking so long - I wish I had more time for messing about with
fractals. Sadly that may be one problem that cannot be solved
with a new version of fractint.

   OK, I'll have one last go at this (rather off-) topic:

   Godel's theorem, which Penose presumably cites, states that in no 
system (meaning set of rules and axioms) complex enough to describe 
itself (ordinary formal logic could be an example of such a system) can 
it be shown that the system both complete (meaning that all true 
statements about the system can be proven in the system) and consistent 
(meaning that no paradoxes can be derived in the system.) This means, 
for example, that it cannot be proven that any of our systems of 
mathematics is 'perfect'. This proof is not particularly recent; it 
occured in the first half of the century, though I find I can't remember 
when...

   As for the paper mentioned stating that Turing machines can compute 
uncomputable problems, I'd be fascinated to hear this...

   Ed Avis made a comment which I believe to be erroneous regarding the 
ability of Turing machines to model physical law. Nondeterministic sets 
of rules are quite within the understanding of automata theory; they are 
described as "nondeterministic finite automata" and are certainly 
modelable as Turing machines. The universe might not be so describable 
were it not finite (possessing a finite number of rules and a finite 
space) but it is generally felt, though certainly not proven, that it is. 
   I suppose that when I refer to a finite number of laws or rules, I am 
implying that the universe is "algorithmic" in the sense that all of its 
behaviors are describable by some set of rules. It is certainly 
concievable that this is not so, but I would have to say that such a 
claim falls outside of anything that can be considered scientific yet...

Instead of removing all "3D"s, replace all "=3D"s with "="s, since there
are valid uses of the string "3D" in some pars and frms.

Err... no, the list server doesn't have anything to do with this
really.  It isn't the source of the =3D's nor is it interfering with

hmm, I DO care if the render time goes up...
Win95 has a horiffic processor overhead, and while this is
fine on a fast machine (most programs dont use very much
processing power) for processor intensive work (like fractal
and 3d rendering) DOS is better by far - up to 2.5 times
faster on my machine.
Until microsoft come up with ways to multitask DOS apps I
think I'll stick with the good old reliable DOS mode, even
if they came up with an easy way to allocate system
resources Id be happier.
I dont see any reason why I should have a fast machine yet
only use a fraction of its power just because thats what
Uncle Bill has decreed.

There is another issue as well...ie graphics modes.  Windows
is very strict about screen resolutions, and would you
really want to restart your machine every time you wished to
change resolution?

Subject: (fractint) Client-server Fractint
Date: 08 Jan 1998 18:29:24 -0000

I've been reading some responses to my suggestion that Fractint v20 should 
run on a client-server model.  The consensus seems to be that it would be 
nice, but might be difficult to implement (especially in DOS) and that 
other features should come first.

In some ways I think that client/server Fractint could actually be easier 
to develop than the present form of the program.  The reason for this is 
that the server part would be the same across all platforms (DOS, Windows, 
Unix, whatever).  The platform-specific code could be isolated into the 
client part.

This would mean that Winfract and Xfractint would stop lagging behind the 
DOS version in terms of features.  If a new formula or new calculation 
engine is introduced, it gets added to the server, which is the same on all 
versions of Fractint.  (Of course, some would also require enhancements to 
the client, but most would not).

There is a TCP/IP library for DJGPP (and threads packages), so if the DOS 
version will be compiled with DJGPP (as seems likely), portability to DOS 
should not be a problem.  Similarly there are good Winsock implementations 
for Windows.

On the other hand, I'm not one of the Fractint developers, so their 
opinions on what would be "difficult", and what features are higher 
priority than others, carry more weight than mine.

   The client-server model is clearly elegant, but definitely introduces 
overhead. Would anyone with a really deep knowledge of communications 
protocols, processor cycles, and fractint's current design care to 
comment on how much overhead we're talking about? I mean, if calculation 
is 80% of fractint's drawing time on a typical Pentium, and drawing is 
20%, would some sort of multithreaded client-server design add on another 
20% of time, or 600%, or what?
   I suppose 'multithreaded' is something of an assumption; to some 
extent you could separate out the two sets of routines (calculating and 
drawing) without really slowing down the code... hmm. Don't know enough 
about fractint's design, do I.

The server part also has platform-specific code.  For instance, the
Pentium has 80-bit floats, but IEEE doubles are 64-bit floats.  The
new 64-bit SGI machines might have a "double" that is 128 bits.  Since
fractint switches from floating-point arithmetic to arbitrary
precision arithmetic when the floating point code runs out of
precision, it needs to know the sizes of the various floats and doubles
in order to know when to switch.

Xfractint doesn't lag the DOS version at all.  They use the same code
base.  However, winfract lags because it is a completely different
kind of port to windows that doesn't share the code the way the
xfractint port does.  Fractint should be made more portable so that
contributions to the engine part of fractint can be shared on all
platforms, modulo the compatability issues discussed above.

If any networking is introduced into fractint, it should be TCP/IP at
this point.  There was a time when IPX seemed important in the PC
networking world, but except for corporate LANs IPX seems to be giving
way to TCP/IP in most markets, certainly it looks that way in all new
networking stuff that's created.

I think people generally work on what they think is neat :).

Fractint is currently going through some teething pains as it hits
puberty and outgrows its 16th bit.  Developer discussions I've seen
say that the roadmap for the future looks like: 32-bit flat DOS
application, more integrated ports between X11-unix/Windows/DOS,
24-bit rendering.  I think you'll eventually get what you're asking
for out of fractint, but you're going to have to wait a while if you
want other people to do the coding :)

How the duty cycle splits between display and computation depends very
much on all the inputs.  For deep zooming, distributed processing
becomes a huge win because computing each pixel takes so long.  For
the default M-set screen, the computation can probably be completed
locally before you can even assemble all the distributed pieces into a
picture over a modem.  Typical factors affecting the performance would
include communication speed, processor speed, and scatter/gather
overhead.  I'm not aware of any way of optimally allocating the
resources such that you can always guarantee that you produced the
image in the shortest time possible.  However, its probably reasonable
to build a heuristic that does the right thing 90% of the time.

I like to use fractint with showdot=b/20, but I have noticed that when
the processing time per pixel is short, that this actually slows down
the display.  I think it ends up spending lots of its time bitblting
the little triangle bitmap in and out of the video memory compared to
the time it spends computing the pixel.  However, for very slow (i.e.
deep zoom or complicated formula) renderings the showdot=b/20 overhead
is minimal compared to the total rendering time.  Also, with slower
renderings, I want to know where the computation is more than with a
faster rendering.

Microsoft has some useful items for downloading from their site.  They
are usually referred to as "Power Toys".  One of these is a small
executable to be put into your StartUp path, called "QuickRes".  It will
stay in your System Tray and allow you to instantly alter your monitors
resolution without rebooting.

It has always worked fine for me without any problems.

This is only true if you don't change the depth of the pixels.  So if
you switch from 1280x1024 256 colors to 1024x768 16-bit color, you
will still have to reboot.

You can solve this potential problem by enclosing the URL in <URL: >,
as in <URL: http://www.yahoo.com/>.  The <URL: > enclosure has been
proposed as a way to embed URLs safely within other text files and
have them be easily recognized and extracted by programs.

That's just it... the compuserve software isn't thinking at all; it
just puts printed-quotable on every message it sends.  At least, that
is what the compuserve technical support people seem to be saying.

Yes, other people have been sending a few messages that are this way.
However, although I didn't do an exhaustive search of every message
ever posted to fractint, I just looked over the ones I'd gotten
recently.  Of those, the ones with content-transfer-encoding of
printed-quotable were from:

    Lee Skinner <LeeHSkinner@compuserve.com>
    Les St Clair <Les_StClair@compuserve.com>
    Sylvie Gallet <Sylvie_Gallet@compuserve.com>
    guy.marson@mnhn.lu (Guy Marson)
    "Steve Jenks" <SGJenks@foxcomm.net>

With the two non-compuserve addresses accounting for only 4 messages
out of 42.  Of those 4 messages, one originates from a place on the
globe where iso-8859 is the natural encoding (i.e. europe) and the
others are in printed-quotable because of the way Steve Jenks appears
to have configured his email program.  (Microsoft Outlook Express)

There is one strange one however.  Clamcake forwarded one of my
email (when the server was messed up) and it got the =3D sickness

Excuse me, but you are incorrect.

Have you ever used, or do you use, the "QuickRes" utility that I
mentioned???

I can go from the following modes back and forth in only about a second
with no reboot what-so-ever:

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1280 x 1024  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)
   1024 x  768  @  HiColor (16-bit)
   1280 x 1024  @  HiColor (16-bit)

    640 x  480  @  TrueColor (32-bit)

Besides, "Bagpuss" only mentioned changing resolutions (the number of
pixels in the image horizontally and vertically).  Nothing was mentioned
about the amount of colors available (even though it may be done without
reboot). 

Resolution is the amount of definition and clarity in an image.  The dot
pitch of a CRT display monitor affects resolution.  However, resolution
is usually measured in terms of the number of pixels ("picture elements"
or screen "dots") per square inch.  By varying the display device driver
the operating system is using, a user can vary the resolution of the
monitor by changing the number of lines on the screen and thereby
altering the number of pixels.  For example, one could reset a Windows
setup to select a driver that provides an 800 (horizontal) by 600
(vertical) line display. 

The upper limit of resolution for most PC monitors is about 72 to 100
pixels per inch. As a comparison, most PC printers offer 300 to 600 dpi
(dots per inch) resolution.

Yes, and it required me to reboot if I changed the pixel depth.

Must be something unique with your system setup.  I have been using is
for around two years now without problems.  And all of my friends and
work associates that use it have never had any problems either.  In
fact, there are thousands of individuals that use this.

Maybe you should try downloading it again from:

   http://www.microsoft.com/windows/windows95/info/powertoys.htm

And then give it another try.

I'm using P166 Win95 version 4.00.950 B and not the greatest
amount of video RAM. I'm not using QuickRes, but I can
change among these without rebooting

    640 x  480  @  256 color (8-bit)
    800 x  600  @  256 color (8-bit)
   1024 x  768  @  256 color (8-bit)
   1152 x  864  @  256 color (8-bit)

    640 x  480  @  HiColor (16-bit)
    800 x  600  @  HiColor (16-bit)

But if I want higher resolution I can get

   1280 x 1024  @  16 color
Going to this one I must reboot.

I think there is a Win 95 version dependency here.  An older
version on a P200 with bigger monitor and more RAM had
to boot as I recall. I'll check it again later.

I believe that the reboot requirement depends on your video card.
So as I said before, even though you have the MS "power toy", you
still may be required to reboot when changing video parameters.

This could be possible, or it might have to do with the OS release
level, or drivers and release level, or some combination of these.

Well, not quite what you said before.  But, at least you have revised
your original "will still have to reboot" to "may be required to
reboot".

I'm slowly catching up on reading hundreds and hundreds of e-mail
messages. Read this one today that was posted to the list server on New
Year's Day:

Question: Is the equation z=cos(z)/z+pixel correct? If so then c=z=pixel
is not needed & should be rewritten as z=pixel. If, on the other hand,
c=z=pixel is correct, why is there no "c" in the equation? In other
words, is "c" being used or not?

Taking Bill Rossi's recommendation of this past Monday, how about...
z=fn1(z*z)/z+c or z=fn1(z*z)+c/z+pixel or fn1(z*z)+c/z or
fn1(z*z)/z+c+pixel or, or, or, etc. etc. etc.

Just putting in my two pfennigs.

Hey....I have powertoys too!!!  And I'm a computer dummy......they work
great....I keep the screen resolution do-dad in my tray ....get it!!!
There are some more cute tricks in the package too....

This is only slightly off topic since Sylvie once pointed out to me that
her Winfract color cycled....so does mine in 256 color mode...which you can
re-set with the powertoys thingummy......frankly its easier to run fractint
under windows in dos.....mostly the screen res thingy is good to look at
your web pages in two resolutions....800 x 600 and 640 x 480....or 1200 x
whatever if you are like my son and like to squint.
