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.

Awww, what the HELL???

I thought a "Re:" at the start made it leave it alone!

Frigging thing must look to see if the word "fractint" is already in the
subject, which is far far cleverer than I anticipated.

Answer the question already...we all want to know... <evil grin>

I will get Fractint 20 if I have to pry it from your cold, dead fingers!
muahahahahahahaha!

WTF??? I didn't make any really long postings...no check that. The

It was on-topic I swear!
It may have been about fractal formulas in general but it had examples as
Fractint formulas. z=pixel, c=p1 and so forth.

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? 

Angela

Subject: (fractint) 3DBalls question
Date: 02 Jan 1998 16:26:23 -0000

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........
