If you think about it, you will realize that if fractint allowed
the existing values of variables to affect a PAR, that you'd
never get the effect the PAR author intended. So "reset" puts
variables back to their initial default values.

The "=" part is a version number, so that to the extent that fractint
supports backwards compatibility for a specific feature that is
changed, a PAR will render the same with later Fractint versions.

Aha! I thought something rang a bell about that 1960 one. Version 19.6
right? heh. :)

As far as SOI goes, you might want to take a look at the DOS demo I
have put together from the AlmondBread sources (both from the URL
cited below). I don't think the "disks" algorithm is such an important
feature to have (although it's great work by Yuval Fisher), since you
only get a b&w image and I don't believe it's significantly faster
than a boundary trace. Now, if you want to take Mandelbrot set drawing
to the next level, IMHO you'll need component detection based on the work
by Jay R. Hill in "The Future Use of Fractals" (Jay, I have finally
received a copy of the book and I'll mail you soon about it). It's a
far more advanced version of the inside disks algorithm described in "The
Science of Fractal Images" (which, IMO, is infeasible to implement).

Good luck,

of a circle, or the cusp point and opposite point of a cardioid, you can
calculate away the whole thing and floodfill it. Another approach would be
to spot the components other ways, but I can't think of one that isn't
lossy. For example, draw a series of vertical lines down the image from
points at the top. Stop each when it hits an inside point. What is the
result? These points may be part of a circular arc that can be used to
infer the circle. But the fractured landscapes of some complex formula
types and the "perturbed" M-set (z_0 not critical) would "fool" it. And
how to differentiate a cardioid, so as to at least ignore it?

Hello. I am new to the list, but a long time user of Fractint. I run a
233mhz PentII at home, and an SGI Onyx at work. I do image compositing to
buy food using software called Flame. This setup makes it possible for me
to easily create animations without all that tedious mpegging and avi'ing.
My finished work is at digital video resolution. Another one of my
favorite pieces of software is FAE which I use to create the .bat files
for my projects.

If any of you have any snappy .fae files worth rendering, I'd love to
share some with you.

Anybody else doing the same sort of thing?

Paul,

> Why do you claim the inside-disks are infeasible?

I have repeatedly tried to implement this method and have each time
come to the conclusion that Fisher's method does not work for
arbitrary points inside M. For a lot of points it does work, but for some
the algorithm yields a gross overestimation which IMO makes it
infeasible to include in a general purpose Mandelbrot drawing
program. But I'd love to be proven wrong (although I tried hard
to implement it exactly as described). If you have succesfully
implemented this method, please make it available (if you haven't done
so already and I'm unaware of it).

Sure, that's a good speedup.

For any point c inside M you can find its component center through
Newton iteration if you calculate the derivative of z and the period
of c which is the period of the component. Then calculate Taylor
coefficients for the mapping p:W->D. These coefficients, the center
and the period make up a set of "parameters" which describe the
component. Now if you suspect a point c to be inside M, calculate the
approximate value of p(c) for a list of components you set up as you
scan the image. If p(c)<1.0 then c is inside the component. In-depth
coverage can be found in Jay R. Hill's article in "The Future Use of
Fractals". I've had some success implementing this method (disks work
beautifully), but I've had some trouble with the cardioids. As with
SOI, this method should prove advantageous for very deep zooms.

What about outside disks? I tried those once and it sometimes
overestimated...someone told me there was a slight bug in the algorithm as
described in The Science of Fractal Images. I'd like pseudo-code for a
working outside-disks. Perhaps the same thing is causing trouble with the
inside disks!

Okay. But what is the mapping p? For a disk, it's (x,y)*const+(a,b) for
the center a,b and radius const of the component. How do you determine,
though, that it is a) a disk and not a cardioid, b) const and a and b, and
c) what are the mappings for cardioids etc.?

I wonder if anybody has encountered this problem with saving an image to a
parameter file. It occures  when the bailoutest-parameter (z-screen) is
combined with continuous potential (y-screen).

I had an image in which the bailoutest parameter was set to imag and
continuous potential activated. I wanted to examine the effect of different
values for the potential-bailout value. So I stored the image to a
parameter file with the b-command, changed the pot.-bailout value a few
times and stored every image to the parameter-file, without letting
Fractint fully calculate. I made a DOS batchfile and let it run.

To my surprise I found that in the first image the bailoutest-value
(z-screen) was set to imag, in the other images the bailoutest-value was
set to the default-value of mod. When I examined the parfile I noticed that
only the first entry had the bailoutest=imag statement. In the other
entries it just wasn't there. I tried this procedure another time and the
same thing happened again.

So it looks like as if when you change the potential-bailoutvalue and use
the b-command to store the image to a parameter-file, Fractint ignores the
bailoutest=xxx command and doesn't store it.

I have a parameter-file attached. Can someone please have a look?

I know I can fix the file by editing it with a wordprocessor, but that is
quite a hassle every time. Is it possible to have this fixed in the next
version of Fractint?

Thanks in advance!

Cheerio,

Jacco

Thank you very much.  I should have known it must be easy.   :-)

Now, is this a bug?  Might pass as FoTD if it had a romantic story to
go with it.

I zoomed in on the right most period 12 midget and switched to the
Julia set view.  Now look at this.  Something is wrong.  A flaw here at
magnification 1063 begins at magnification 20.  Press the space bar
to see the midget, up close. It is one from my complete collection
(coordinates found as part of the MSet area project).  Speaking of
collections, did you know Fractint has a limit of 2000 samples in a
par file?  I found out!

The latest Pentiums are fast enough that it takes longer to press
SHIFT-@, DOWN arrow, ENTER than to draw the image.  Is there
a 'next' par image key which will get the next one without leaving
the graphics mode?  Also, in zooming in, it takes longer to get the
dozen or so PageUp key strokes in than to draw images.  At least
until you are at 1e12 magnification or so.   A keystroke to get the
max-zoom box would be nice.  BTW, the fact that the zoom box stays
centered on the center coordinates is very useful.  Looking for very
small features is easy when you have the coordinates. Of course,
you can press Z, F6 and type in a new magnification. But the view
along the way is the fun part of zooming.

For deep zooming, I use a trick to make Fractint draw a small view for
early sampling and still keep the 1024x768 setting. It is to put the zoom
focus in the upper right of the little zoom box. Press ENTER to start the
zoomed in image.  Before it gets far (as quick as you can) press
PageUP then CTRL-Right arrow forcing the calculation to the left side.
Now the calculation will occur in the upper left corner. Usually I see the
next level of interest in about 20% of the scan down the screen. If I
have missed, I can hit PageUP, UpArrow and/or Left Arrow and fill
in a narrow strip in those directions.  This will help you in DEEPZOOM
mode where you are looking for a midget (and hoping you are
not caught in a Misiurewiz trap).

For slow deepzoom exploration before reaching a "target", what I do is use
a tiny view-window. 'v', yes, and 4 or 5 does the trick. then 'v' and no
to draw the target fullscreen. (Of course, you didn't know how to turn
off the view windows before...:-))

Date: 02 Sep 1997 20:55:50 -0700

Hello Everyone,

Have been a Fractint user for ever. Remember XT's and CGA? Fractint was there
and still is with my every upgrade, and still a"DOS" program. Even with Win95
I use dos as much as possible, (I do have Fractint on my desktop too).
I have been on the list for a week and am thrilled that there are so many
Fractint users out there. I am terrible at reading documentation so have
been learning
many things.

For the Fractint Wish List -- a catalog feature to compare the subtle
differences
between commands. As it is I use a dos program GifDesk 4.5 to view the Gifs.
Another nice utility would to be able to delete those gif files that have
been altered
after using fractint. I seem to have alot of fractint gif's that I have d/l
and can't use.

                               Cindy Mitchell

Did you know that you can create a "color plug-in" par file by editing ou=

everything but the colors=3Dstatement?
You can use this method to annotate your color collections so you never
forget where they came from, like so:

JAY_001       { ; I borrowed these from Joe Bloggs
  colors=3D000AAA<6>SKEULEWMEYOF_PF<5>nYIpZIs_Ju`JxbKzcK<20>AAA<20>hcz<21=

  }

Once you've drawn an image just open your "colors" par in the usual way a=
nd
Fractint will simply read in the new colors.

I don't think so, because the inside-disks approach is very different
from the outside one (as you know, not just set x=1 instead of 0 and
it works for inside disks as well). I used to have a working outside
disks (years ago), maybe I'l hack up one again when I have the time.

p (rho) is the product of all z's from z_n to z_{n+p} where p is the
period. At the component center this is 0. Besides Jay's article
there's some about it in "The Beauty of Fractals" in the Mandelbrot
chapter. You don't need to know if it's a cardioid or a disk, just if
it's inside or not, although Jay describes a heuristic to determine
disk/cardioid.

Let me be a bit more precise. The hash count idea requires a new
thinking about a formula.
Let a formula have a "description part" and one ore more
"implementation parts".
The "description part" describes the "formula mathematics" in a
normalized formal format (which we have to define; OK lot of work!).
The hash count (or fingerprint or whatever) is taken from the
"description part".
The "implementation parts" describe some implementation of the
"formula mathematics" (like an entry in the well known frm-file).
Changes in the implementation parts (like different variable names,
if-then-else structure etc.) would not affect the hash count.
So what we need to identify a formula is its hash count (or whatever)
and its implementation name (if there are more than one
implementations).

Hope this helps to clearify the idea.

Peter

Date: 03 Sep 1997 09:05:52 +0500 (GMT)


Hello,

This is something that I found while I was experimenting with the lyapunov
exponent for the mandelbrot set.
The idea was to calculate the expontent for every point that is inside of
the set, and since the points that nears the boundary becomes more chaotic
as they came close to it, I espect level sets coming from the center of
the M. set to the boundary. but the history is another, because instead of
the level sets, the inside of the set (and of every bud) has a radial
estructure, with rays that come from the boundary to the center..
The julia sets too, has a weird (but beautiful) lakes, so check this par
and formula file, and if anyone knows why that happens, I wish to hear the
explanation...

Justin,
The printing capabilities of fractint are quite rudimentary. I don't think
many people print directly from fractint. You are much better off using a
third party program. If you are running Windows, get the shareware program
PaintShop Pro. It is easy to use and does a great job of printing fractals
on my Deskjet 870.

or more "implementation parts". The "description part" describes the

I'm always ready for new thinking! Perhaps you could give an example - here
are two formulas, the second of which is a simple optimization of the
first. These formulas would produce identical images. Could you show what
the "description part" of each of these formulas would be? Presumably it
would be such that if the formulas were written by different persons, the
description part would be the same.

Example1 {
  z = c = pixel:
  z = z * z + sin(c)
  |z| < 4
}

Example2 {
  z = pixel
  c = sin(pixel):
  z = z * z + c
  |z| < 4
}

A bit more challenging <g> would be to take the "before and after" versions
of the Carr2821 formula (you can get these in the if..else tutorial that is
part of the fractint 19.6 package) and show how independent writers of
these two formulas would generate the same descriptive section.

Someone asked me a year or so ago if it would be possible to go through the
Orgform compilation and weed out "duplicate math" formulas, so I have
already given a bit of thought to the idea of formula "content". Some
things are easy, such as recognizing that the name of a variable does not
affect the underlying math (in fact, when orgform.exe decides to skip a
formula because it is identical to a formula of the same name already in
the compilation, it makes the comparison without regard to names given to
variables). Order of operation matters are probably in range, such as
recognizing that z = a*b is the same as z = b*a. Algebraic equivalency
becomes harder; recognizing the equivalence of such expressions as (x+y)^2
and x^2+2*x*y+y^2 opens up a Pandora's box of Goedelian proportions.
Developing an algorithm to recognize the equivalency of major rewrites such
as with Carr2821 seems unimaginable to me.

George Martin

This thread started when I wrote the 'Those awful viewwindows' note. Now I
see the 'v' key fixes that. Now, I looked for 'periodicity' in the
fractint.doc.
It again looks there is no hot key for this. I locate a midget at high
magnification with solid gueesing on, periodicity on and any other gimic
to make it fast. Now I just press space bar twice and get the Julia set.
How do I easily get periodicity=0. What I find is par file methods which
would put me back to what I was (needlessly) complaining of earlier.

(Fractint programmers note: no offence ment by any of my rants!  Been
programming for 35 years, so I have some hint of what produced Fractint.)

Here is my sci.fractals sig:

int main(){float g,s,f,r,i;char*_="!/-,;<:!lnb/bh`r/ylqbAmmhI/S/x`K\n";
int m,u,e=0;_[32]++;for(;e<3919;){u=(256*(s=(r=.0325*(m=e%80)-2

The "G" keyboard command lets you give a startup parameter interactively.
From there you can say periodicity=no to turn this feature off.

Dear Justin:
Try using the Windows port of fractint.  Save the fractal in BMP
format and use the Windows printer drivers that came with your
printer.  This always works for me.

Hi.

I am new to the list also, however I have been printing fractals for
various purposes on my HP 660Cse for quite sometime. This is pretty much
what I do, if it is any help:

If I have constructed a fractal through fractint, I will save it as a .gif
(smaller file than a .bmp) to the desktop (associated with LViewPro), and
if desired make changes to the image if desired either in that program or
another, then click on "edit" at top, "copy", bring up WordPad (or
WordPerfect), click on Edit at top again, then paste. From there I will
resize if putting on a postcard or using as kind of a logo thing on a piece
of paper for letter writing, or to make a greeting card with - whatever,
then click on "file" and "print".
After which I then save the file (image) on 3.5 disk and remove the image
file from the h/d.
This is all under Win95.
Hope this helps, and hope I did not waste anyone's time.

Description parts...hash counts... I dunno about you but it sounds simpler
to me to just pick unique and imaginitive names. :-)
In fact names based on your initials, and avoiding using a duplicate name
yourself or doing any renaming, you can probably guarantee no duplications
of other peoples' formula names too.

Or a naming convention based on math could be done.

Or, a hash count based on an actual value gnerated by the formula?
Perhaps, a sample image in a 32x32 thumbnail kind can be calculated for
some fixed values of p1, p2, p3, and the pixel range, and this can then be
encoded into a hash? (The image would use maxit 2048, floating point yes,
periodicity=no, and other options their defaults, outside=iter, inside=0.)

2 ways.

One is this: hit 'g', this pops up a dialog for entering commands to
fractint's brain. (ProtoMatter will include a command console for similar
purposes.) Type "periodicity=no" and enter. To put it back later do the
same but use "yes" in place of "no".

The other: copy this and paste it in notepad and save as a par file, like
"periodic.par":

----8<----

PeriodicityOff {
  periodicity=no
}

PeriodicityOn {
  periodicity=yes
}

----8<----

Then use @ to load one or the other, to switch it on or off. (Since this
has no reset= in it, it won't do a whole new image the way normal par
files do.)

Tim: any chance Fractint 20.0 could make periodicity switchable on the 'x'
screen like floating point? Also, how about allowing formula writers to
specify a default for floating point and periodicity? That way formula
writers can force fpu math, and can default periodicity off for formulas
(like many rationals or formulas depending on earlier iterations of z)
that tend to goof up with periodicity on.

"Port" means that the authors of fractint didn't recode the whole
DOS program from scratch---they reused large portions of the original
DOS program and made some relatively small modifications in order
to make fractint work under Windows.  (Keep in mind that the DOS
version still works fine under Windows if you aren't printing.)
Winfract will save fractals in BMP format and from there Windows
---using Paintbrush, for example---can print the fractal using the
Windows print drivers that came with your printer.  As already stated
you can also use Paint Shop Pro to convert the default GIF format
to BMP in order to print the fractal.  Just go to
http://spanky.triumf.ca/pub/fractals/programs/ibmpc/windows/winf1821.zip
to get the latest version 18.21.

I've been tinkering with some of the source code for fractint using
Visual C++ version 5.0 which is not satisfactory since there are
some keywords declared "obsolete" and other problems.  The authors of
fractint used Microsoft C version 7.0 to compile the source code but I
can't find this version.  Does anyone know where I could find this
(old?) product?

OK, I will try it! In fact, Example1 and Example2 are two
"implementations" of the same formula. So the "description" and
"implementation" parts may look like:

FORMULA {
   DESCRIPTION {
     z =3D c =3D pixel:
     z =3D z^2 + sin(c)
     |z| < 2
   }
   IMPLEMENTATION {
     Example1 {
        z =3D c =3D pixel:
        z =3D z * z + sin(c)
        |z| < 4
     }
     Example2 {
         z =3D pixel, c =3D sin(pixel):
         z =3D z * z + c
         |z| < 4
     }
   }
}

Of course, it will be a hard task to create a "standard" for the
description part! This part should be a mathematical one: we should
replace "pixel" by a something like [(Xmin, Xmax),(Ymin,Ymax)] and
we don't have care of optimizations etc.

To recognize such equivalences, algorithms used by good symbolic
math programs would (hopefully) help; but I'm not an expert ...

There is no need to recognize rewrites or optimizations because this
are "implementations"; just add it to the formula's implementation
part (or exchange one implementation).

To identify a formula, get the description part's hash count;
if there is only one implementation, OK use it,
otherwise, we have to decide which one FRACTINT should use.
Or, FRACTINT uses always the first implementation and we exchange the
implementations as we need them.

Sylvie,

I looked at the HTML source for your page. It is only a gif file. Not HTML.
  The
problem is likely that we don't have the address of your home page.

If might be something like this

http://ourworld.compuserve.com/homepages/Sylvie_Gallet/index.html


My homepage server defaults to a file named  'index.html' when one does
not specify the file name.

This does not work for yours.   Hmmm...

Sounds cool. Hey...aren't you the one who got the Millenium 1600x1200x256
VESA mode working in Fractint? I love that mode for generating big
detailed B/W/greyscale images for printing on laser printers.

I've seen this too-- a "full-screen" fractal in Fractint takes up *more*

Could you please explain xactly what you do - what video mode you are
using, and how you know the image is bigger than the screen.

Are you talking about Winfract or Fractint? Winfract uses a virtual
screen that doesn't have to match the actual screen. Also, Winfract
is no longer supported and is frozen in time forever ...

  Yes, it's me!  I think that 1600x1200 is not necessarily the best
resolution for making detailed prints.  The size of the image must depend=

on the resolution of the printer and the size of the print.

fractal galleries, looking for some new ideas, etc., and somewhere heard =
about alt.binaries.pictures.fractals. It was not available on my server, =
so I called and got the guy to agree reluctantly to add it after =
explaining to him what the Mandelbrot set is, etc. Now they were under =
the impression it contained pornographic material, which I thought would =
be kind of weird for a fractal gallery. So, anyway, I've been checking =
it out every day and finding some cool stuff there but also some =
unexpected things. Can anyone please explain (I'm really new to the =
internet, so maybe I sound like an idiot) why there are XXX messages, =
whatever those are, credit card advertisements for people with bad =
credit, and so forth, at a fractal gallery. I am in favor of free =
expression on the 'net and am not a crank or anything (at least I hope =
not) but this is just something that's been puzzling me.

    And now this is a Fractint question: when I run my demo program, =
which I actually find quite helpful, it freezes after printing an image =
of the Mandlebrot set (it's on the second demo file, I believe). Is it =
my computer, or should I go look through the source code?

Hi, Peter!

I don't think there is anyone in this audience that would disagree with
you!  The non-fractal postings violate the spirit of the newsgroup and the
abpf newsgroup FAQ.  Unfortunately, we haven't been able to find a way to
stop them.

Most of the people (and I use the word loosely) who post spam to abpf are
making postings to alt.binaries.pictures.*.  And abpf is caught in the net.
 Those same people usually have a financial interest in attracting as many
others as possible to their web sites or their pyramid games.  So they
really don't care at all about the rules.  To them, only their own
self-interests matter.

We tried to discourage them by requiring certain keywords (fractal,
mandelbrot, julia, etc.) in the subject line, and then installing a retro
cancel 'bot to cancel every posting that didn't include a keyword.  We were
hoping that when they got their postings cancelled from ALL the newsgroups
by our 'bot, they would exclude us from their spam postings in order to
protect their own interests.  We were moderately successful (a RETRO 'bot
can't be completely successful, plus some of the more inventive spammers
started using the keywords in their postings!).  Then, Dick Depew, the
person who wrote and maintained the retro 'bot, had some rather serious
computer problems, and for the last 6 weeks or so, his computer has been
down more often than not, so we are getting spammed again!  Hopefully an
end to Dick's problems is in sight, but no promises can be made!

We keep trying . . .

If anyone has a brainstorm on how to solve this problem, please speak up!
Consider this a cry for help!

Linda

Hi,

I have had the same problems with NT 4.0 - and still have them.
I asked several questions to Matrox' tech support but the answers
couldn't help me. Here are CCs:

---Question #1---
Hi,

I have problems with SVGA modes when starting DOS application
from a DOS prompt, eg FRACTINT. My monitor can't sync any
SuperVGA video mode! I have no sync problems with the Windown
NT 4.0 drivers. In addition to that: it makes a difference whether
I start FRACTINT from the DOS prompt in window on the Windows
desktop or from a DOS prompt in full screen mode (text mode).
In the first case FRACTINT says that these video modes are not
available with my adapter, in the latter case it tries to switch into
the SVGA mode (from 640x480x256 to 1280x1024x256) but
obviously cannot sync it.

Here's my configuration:
Matrox Millennium, 4.0MB, RAMDAC TVP3026A, 220MHz, Serialnumber
AAC42011, VGA BIOS-Version 2.3, MGA PowerDesk-Version 3.12.046,
DisplayDriver Version 3.12.046.
Monitor's horizontal line frequency: up to 84kHz.

Do you need more info?

Thanks,
Stefan.
------

---Answer #1---
Try the mgamon utilty from the setup directory on th mill cd. this will
setup the monitor for dos mode.
Chris.
------

---Question #2---
Chris,

I tried the mgamon.exe utility that came with the bios23 update
but everytime I start it from Windows NT 4.0 it produces a
horrible sound through my computer's speaker and then just says
"No board(1)".

What now?

Thanks,
Stefan.
------

---Answer #2---
The mgamon.exe file was not intended to be used with windows nt.  It is for
dos, but can also work with win95 and win3.1

ThankYou
------


So I still have no idea how to solve this problem.

Stefan.

 make a commercial posting informing
readers of your services, investigate the "biz" hierarchy of newsgroups,
which exists for such purposes. Be courteous to others by posting
responsibly; you will not only help to improve the quality of Usenet but
also avoid the backlash risked by ignoring basic rules of "netiquette".

In a nutshell, newsgroups are a means of "public discussion".  Newsgroup
articles (messages) look like e-mail, but they can be read (potentially)
by millions of people all over the world.

Newsgroup articles are distributed via "news servers", which contain
databases of articles, and are operated by Internet service providers,
schools, universities, and companies.  There is no "central" server on
Usenet.  A newsgroup article propagates from one server to another,
starting from the server where it is first posted.

"Moderated" newsgroups are sort of an exception, in that all articles
are first forwarded via e-mail to a "moderator" for approval.  The
moderator posts them on his/her news server, and from there they
propagate as described below.  But different moderators use different
news servers.

Ideally, all the articles in a newsgroup travel to all sites (news
servers) that carry the newsgroup.  This means that when you post an
article, the final result is tens of thousands of copies, all over the
world.

More specifically, when you post an article, it goes first to your
"local" news server (operated by your Internet service provider,
company, or school).  Your server then sends copies of the article to
its "neighbors," that is, to servers with which it has agreed to
exchange articles.  Those servers in turn send copies to *their*
neighbors.  Eventually every server that carries the newsgroup has a
copy.

Most servers normally send articles to other servers more or less in the
order of arrival.  This sequence can get scrambled for various reasons,
which is why you often see responses before the "original" article
arrives.

News server administrators make arrangements among themselves about
which newsgroups they exchange.  The "receiving" server's admin tells
the "sending" server's admin which newsgroups he/she wants to receive.
The "sending" server's admin configures his/her server to send only
those newsgroups.

There are two methods that servers know which sites they've already
visited and how a message avoids the same site twice.  Servers usually
use both of them, in sequence:

1. The "Path:" header line shows the sites that the article has traveled
through, so far, between the originating server and the current server.
If the "receiving" server appears in the "Path:" line, the "sending"
server does not try to send the article because it knows that the
"receiving" server has already received a copy.

2.  The "Message-ID:" header line contains an identifying code which is
different for every article.  Before transmitting the article, the
"sending" server asks the "receiving" server, in effect, "Do you have an
article with Message-ID such-and-such?"  The "receiving" server responds
either "No, please send me a copy," or "Yes, I have it already,"
whereupon the "sending" server either sends the article or goes on to
the next one.

Each news server "expires" (removes) old articles, usually once a day,
to make space for new ones.  Most servers do this based on the number of
days an article has been on that server.  The "expiration time" varies
from one server to another, and can also vary from one newsgroup to
another, on the same server.  It might be a few days, or it might be two
weeks or more.  So, even after an article expires from your own server,
it is probably still visible on many other servers.

Note, however, that even though you cannot see an article any more, it
may still be present on your server.  Most news-reading software keeps
track of which articles you've read, and shows them to you only once.
This way, you don't have to wade through the same articles over and over
and over again.  There should be a command or button or something which
"shows all" or "shows previously-read" or "unmarks" articles, so that
you can see all the articles that have not yet expired from your server.

Hi Folks,



  In view of the fairly large number of requests for new features in
fractint that this group gets I have put up a new web page where such
things can be recorded in easily viewable form. It will be watched by
the members of the Fractint development team for new ideas and will act
as more of a central point to gather information than email to
individual programmers can be, putting your ideas forward this way gives
a better chance of the right person finding out.



So don't be shy! go and have a look at:

Damien,
    Well, I thought I had figured the problem out, but it seems that
no matter what I do, I cannot get any more than the first 50 iteration
values to read in correctly.  The copy of my program below *should*
compile for you with a C++ compiler (I use gcc with the -lgpp switch).
The header reads in perfectly, and then the program is supposed to read
in the first 100 pixel itteration values and store them in a dynamically
declared array (if you have a tip on how to dynamically declare a 2d
array, I'd be interested to hear it!).  The first 50 iteration values
read in just fine, but the next fifty are being misread.

    You;ve been a great help already, Damien; if you have any
suggestions for me, I'd be grateful for the help.  Have a good weekend!

Hi:

Mike Sukop here. New list member, new FRACTINT user, new Ph.D. candidate at
the University of Kentucky. Specialize in fractal applications to soil
science, especially surface chemistry.

I would like to be able to get an ASCII file (x,y,z) of the data that makes
up a Plasma fractal. I looked for the subroutine PLASMA() in CALCFRAC.C but
couldn't find it. (I'm a returning student and don't know 'C' yet either --
It wasn't around when I was last in college.) Is this possible? It seems
like it would be almost trivial.

Alternatively, does any one know the where to get the original PLASMA.ARC
Pascal program distributed by Bret Mulvey or how to get in touch with him?

Does anyone know of other Random Mid-point Displacement fractal generating
programs that might have ASCII output?

Finally, does any one know how the 'graininess' and possibly other
parameters of plasma clouds translates into their fractal dimension?

Thanks,
MS

Date: 07 Sep 1997 11:53:41 -0400 (EDT)


I have a tiny question. I would like to know if there's a way to access
the basic formulae in Fractint, ie, to see, say, the basic Mandelbrot
formula in a text editor. I'm trying to understand writing formulae by
attempting to reproduce the basic ones myself by starting with Lambdafn,
and for the life of me I can't make anything Fractint will accept. This is
what I came up with:
Lambdafn {
z(0)=pixel, (also tried z=pixel and z=0=pixel (monkey at keyboard approach))
z(n+1)=lambda*fn1(z(n)),
|z|<64
}
Naturally if I am unable to figure out something like this, my confidence
in coming up with a new formula on my own is not very strong.<G> No matter
how I alter that, Fractint tells me (sternly, with that awful raspberry it
makes when it dislikes something) that z is undefined.
  I've seen the formula for Mandelbrot in frmtutor.txt, so I have one, but
I'd like to be able to see the others.--Alice, feeling doomed and mortified<G>

Here's two things that will help you in creating formuals:

At the DOS prompt where you have Fractint, type in "makedoc fractint" to
create a lengthy document that explains all of the bells and whistles of
using the program, including the various formulas that accompany it. You
can either print it or read it on screen if you wish. You can also
access the document directly within Fractint by hitting the F1 key. You
do not have to type "makedoc fractint" to access the online document
because it's part of the program. I mentioned the "makedoc fractint"
command because many of us like to keep a print out by our side for
reference while using the program.

Also, go to http://spanky.triumf.ca/pub/fractals/formulas/ and download
FRMTUT.ZIP. It's a PKZIPPED 41 kb file that'll teach you all about
writing formulas.

These two documents will answer all your questions.

Furthermore, you can read the fractint.frm and other files with the .frm
extension with a word processing program (or at the DOS prompt using the
EDIT or E function) to see how other people write their formulas. And,
you can study the formulas presented here or at the fractal art list
server.

Formula writing for Fractint is not hard and is lot of fun. Go to it!

I'm getting feedback that my question is not clear. Here is what I want.
When you go into Fractint and hit T you are taken to the fractal types. I
want the formulas for those types. Going to fractal type "formula" gets
you to the formulas in FRACTINT.FRM. I want to know if there is a way to
see the formulas as they would look in the text editor for the other basic
types such as mandelbrot. I realize that when I see the mandelbrot and hit
"z" I will get a blue screen that shows the initial condition and
iteration. That information is insufficient for typing out a formula in a
text editor that will make a mandelbrot. I showed that with my attempt to
recreate the lambda formula, where I used the information given me by the
"z" key to try to recreate the lambda formula. If there is a file in
Fractint that lists the formulas for the types, I can't find it. --Alice

  Some of these formulas are in Chuck Ebbert's formula files: builtn.frn,=

builtn01.frn and builtn2.frn.  I don't know if they are in Spanky's archi=

but you can find the formulas in the Orgfrm compilation and reconstruct t=

Alice, whenever you choose a formula to process in Fractint, and go to
the parameter options screen, the formula is presented in a window
underneath the options.
Ie. you hit "T", choose a formula, then the next screen is the options
screen. This is where you should be able to see the formula. Then you
hit enter and the generating screen comes up and starts writing the
fractal. Is this the information you are trying for here?
    The other option is to open fractint.frm in any text editor and
printing it out. You will have a printout of every formula in that file
(all the default formulas that show up when you hit "T".)
Hope this helps.
    Oh, yes, hey everybody. I've been on the list for a few weeks. Mostly
following the discussions and printing out the good stuff. I am an
artist that studied physics for a short bit before I switched to art 25
years ago. Haven't given up my love of numbers yet. I will post a few of
my works in the newsgroup or my web page sometime soon and let you all
know. The discussion in this list have been helping me along some, but
am using fractint on a 486 (running it on a zip drive disk) so some of
the platform discussions don't do me any.
Cheers,
Oliver!

Alice:

As I mentioned in an earlier posting, you MUST read fractint.doc and the
formula tutor document to understand how to CORRECTLY write formulas for
Fractint. That is why I made the suggestion to read other people's
formulas as well as the texts. If you do as I and others suggest, you
will realize that you don't write z(0)=pixel, as found in many
textbooks. Under Fractint, you would initiate with z=pixel: instead of
z(0)=pixel. Instead of z(n+1)=z^2+c, for instance as your basic
Mandelbrot formula, under Fractint you write z=z^2+c, omitting (n+1).
Also by reading the Fractint document you will come to realize that
*lambda* is not in the programmed vocabulary. Don't take what you read
under section 2.12 Lambdafn to mean that you can write *lambda* into
your formulas. Instead, read section 2.35 Formula, which shows you under
*Predefined Variables* and *Precedence* what is allowed to be written
into a Fractint formula. You will readily see that *lambda* is not
listed, and, being unlisted, you cannot write it into your formula. This
is another reason you cannot get your formula to work. Also fn1(z(n)) is
incorrectly written as *n* is undefined in your formula initiator.
fn1(z), fn1(z*c), fn1(z^2-1), and fn1(sin(z)) are some of the ways to
write this part of the equation. So, instead of z(n+1)=lambda*fn1(z(n)),
you could write something like z=sin(c)*fn1(z), and then, on the last
line write |z| <= 64.

One way to write the basic Mandelbrot set under Fractint would be:

Mandelbrot {
z=c=pixel:
z=z^2+c
|z| <= 4
}

You would NOT write it as:
Mandelbrot {
z(0)=c=pixel:
z(n+1)=z^2+c
|z| <= 4
}
It just won't work for reasons explained.

  I presume that you want to translate the following informations into a
formula:

    Real Part of Parameter                               0.85
    Imaginary Part of Parameter                          0.6
    Bailout Test (mod, real, imag, or, and, manh, manr)  mod
    Bailout value (0 means use default)                  0
        (lambda default is 4)
    Classic Lambda fractal. 'Julia' variant of Mandellambda.
        z(0) =3D pixel;
        z(n+1) =3D lambda*z(n)*(1 - z(n)).
    Two parameters: real and imaginary parts of lambda.

  This algorithm can be translated as follow:

  lambda-1 { ; [e-mail], Sep 1997
             ; George, if you're lurking here: don't include it
             ; in the Orgfrm compilation :-)
      z =3D pixel , lambda =3D p1 :
      z =3D lambda * z * (1 - z)
      |z| <=3D 4
      }

  But with real(p1) =3D imag(p1) =3D 0, you'll get a blank screen.  In th=
at
case, a small if..else statement will set lambda to (0.85 , 0.6):

  lambda-2 { ; [e-mail], Sep 1997
      z =3D pixel
      IF (p1 || imag(p1))        ; if p1 different from (0 , 0)
         lambda =3D p1
      ELSE                       ; if p1 =3D (0 , 0)
         lambda =3D (0.85 , 0.6)
      ENDIF
      :
      z =3D lambda * z * (1 - z)
      |z| <=3D 4
      }

  Save lambda-1 and lambda-2 in a text file with the extension .frm (for
example built-in.frm).  In Fractint, hit <t> and choose <formula>.  The
Formula Selection screen displays all the formulas included in
Fractint.frm.  Hit <F6>, choose built-in.frm and select one of the
formulas.

  Hope this helps!

        - Sylvie

Thank you Sylvie. Bob said you can't have the word "lambda" in a formula,
but I guess you can....--Alice

I just downloaded George Martin's OrgFrom, and was compelled to follow his
excellent example.  I had about 50 formula files of my own cluttering up
my hard disk, so I sorted through them, annotated them, and cleared out
the junk and obsolete entries.  Attached is the result, zipped, uuencoded,
and in George's format.  Enjoy.

Kerry, what came through to me was a binary file. Not sure if zip files
make it through the mail-list server, or maybe there is some other
problem. (I am using Netscape that might not do uuencoding. :-( )) Maybe
what would work better, if others have the same problem, is to post a
query to see if anyone would like the file, and if so, send you a reply
direct. That way, only the one's that want it get the big file. And you
can send it to me, just zipped works fine. If I get anything out of it,
will maybe send you an image, if that works for you.
    Glad you are getting organized in the midst of chaos. For most folks,
putting your email address like this:
mailto:[e-mail]
should make it a clickable text that one can then click on and do a
message. Of course, just the address works if one wants to copy/paste.
Thanks,
Oliver!

I just assumed that any binary attachment would get munged by the list
software, but what the hey, it's only bits.  Attached is the zip file.

Hi Alice,

>> Bob said you can't have the word "lambda" in a formula, but I guess
>> you can....

  Yes, you can have the word "lambda" in a formula but you must initializ=
e
it in the init section of the formula i.e. put it on the left of a "=3D"
sign.

  "lambda =3D (0.85 , 0.6)" in the init section of lambda-2 means that th=
e
first value of lambda is (0.85 , 0.6).

  If you don't initialize lambda, its value is 0 and
    z =3D lambda * z * (1 - z)
  will be interpreted as z =3D 0 * z * (1 - z) and you'll get a blank scr=
een.

Hey, they were all in preview mode. I think they were nice. I've
generated them overnight, and now I can generate them again.

Subject: Re: (fractint) Original Formulae?
Date: 08 Sep 1997 04:10:14 -0500

Hello Alice and gang:

I'm being very patient in explaining how to write Fractint formulas. In
my last message posted Sunday, I said that all terms that can be used to
write formulas were listed in Fractint document, Section 2.35 Formula,
under *Predefined Variables* and *Precedence.* I further stated that
*lambda* was not one of those terms.

Sylvie Gallet then posted this formula afterward:

>

>              ; George, if you're lurking here: don't include it
>              ; in the Orgfrm compilation :-)
>       z = pixel , lambda = p1 :
>       z = lambda * z * (1 - z)
>       |z| <= 4
>       }
>

Alice sees this formula and then states that I, Bob, said one could not
use *lambda* in a formula.

I again reiterate that *lamba* BY ITSELF (I'm further clarifying here
with the emphasis) cannot be used in Fractint formulas: Mademoiselle
Gallet's formula is not written as:

   lambda-1 { ; [e-mail], Sep 1997
       z = pixel:
       z = lambda * z * (1 - z)
      |z| <= 4
       }

If it were written that way, it wouldn't work. What she wrote in her
initiator was z = pixel, lambda=p1: She is RENAMING P1, a term listed
under *Predefined Variables*, as lambda. She could have just as well
typed z=pixel, chickensoup=p1: or z=pixel, alicekelley=p1: The formula
would work using chickensoup or alicekelley, which are not found in any
of the terms listed under Section 2.35, because *p1* is being renamed.
But if she didn't tell the Fractint compiler that she was renaming p1
*chickensoup* or *alicekelley* then the formula wouldn't work (see next
example).

                        Next Example
                        ============

This will work as a Fractint formula:

Chicken_Soup-1 { ; Bill [e-mail]
      z = pixel , chickensoup = p1 :
       z = chickensoup * z * (1 - z)
       |z| <= 4
      }

This one won't:

Chicken_Soup-1 { ; Bill [e-mail]
      z = pixel:
       z = chickensoup * z * (1 - z)
       |z| <= 4
      }

I hope I've made myself clear this time.

Now go forth to write many interesting formulas and have a nice day.

Bob Margolis

Last week I sent the following letter to the members of "fractal-art".  The
results were beyond belief.  I repeat the letter here in case some of you are
not mambers of fractal-art.

I probably do not belong in this group although I do use Fractint and am very
partial to fractals.  I came to fractals late in life, being introduced by a
friend who is a retired professor at the U.S. Naval Postgraduate School in
Monterey.  In the beginning I just played with fractals in a program called
"Fractool".

Then after being laid low by a stroke and being unable to work I came back to
fractals.  I found a number of generators (including fractint) that I could
play with and as long as I was now a 70 year old cripple I really wanted to
do something with fractals.

I fell back on an old hobby, that of making hooked rugs.  Finding that
fractals made a great rug suitable as a wall hanging or as a throw rug.  I
now make my hooked rugs from 100% 6 ply wool utilizing fractal images as my
pattern.

I recently made a fractal rug for a N.Y. fractal artist which he will include
in a show he is having this fall.  This was to be a copy of one of his
fractals.  When he received the rug here is a quote of his reaction:

"It is really quite remarkable.  I think the right word is luxurious.  It is
clear the amount of work that went into it is extraordinary.  It's rich
texture, weight and thickness are all a great and pleasant surprise to me.
 My wife thinks it's gorgeous."

If any of you would like to see a picture of my work, Email me and I will
send one back to you.

Sorry!  I should have warned you.  I save all my fractals in preview mode
because they take up less room that way, but I can view them through
ThumbsPlus, which I couldn't do if they were saved in .par/.frm format!

Hmm... well I'm not sure why you think that a plasma fractal has
(x,y,z) data, since its not a 3D fractal type, but a fractal image.
It has a color index at each (x,y) location in the image.

Fractint can take any image and use it as a 2D height field.  Perhaps
that is what you are looking for (the docs suggest starting with an
image generated with the 'plasma' type).

Your best bet is to inspect the file fractint.frm which should have come
with Fractint in its zip. I think it has a formula-format version of the
classic Mandelbrot.

Futz. Those are mine and I posted them in sci.fractals. They should still
be there. If they expired, check dejanews.
Good luck...

Hi Alice,

    It seems to me everyone is making this a bit more complicated than it
really is.  FRM and PAR file are simply straight ascii files.  Any word
processor will view them, ie: Notepad, Wordpad, Word, etc.  I associated
them with Textpad so that I can double click on a file in Windows Explorer
and the file will automatically open in TextPad.

Hi Ed....what I want is a .frm file that has the default fractint fractal

me to a possible source of some of them in Orgform, but I was unable to

Hi Alice:

It's me again. The default Fractint formulas are not in any default
formula file at all. When Fractint was compiled from the C language to
the .exe file, the formulas of which you inquire were written into the
source code. That is why you can see lambdafn, z(0), and z(n+1) in the
formula description box when you look at the nearly 100 default formulas
that came with Fractint.

What I now think you want is some way to translate the lambdafn fractal
type that came with Fractint to a .frm file that would create the same
image, but using those terms that are allowable under the *Predefined
Variables* and *Precedence* paragraphs I cited in earlie messages.

Reiterating, you won't be able to use z(0) or z(n+1) in the formula file
you want to write because, although it was hardcoded into the program,
the user has to write her formulas in a different manner as outlined in
those paragraphs I mentioned. And, lambda was not included in the user-
allowed terms in those paragraphs either. What Sylvie did was to rename
P1 as lambda in the initialization part of her formula, then instead of
writing P1 * z, or whatever the equation was--I don't have it handy at
the moment--she wrote lambda * z. Therefore, for lambda, you would be
asked to enter real and imaginary numbers for lambda at P1.

I hope I'm making myself clear, but if not, here's some more info from
the out-of-print book Fractal Creations, 2nd Edition, by The Honorable
Tim Wegner and his trusty companion Bert Tyler, which was written for
users of Fractint 18.

Pages 282-283...
Lambdafn
Category   Mandelbrot/Julia Generalized
   This type is the Julia variant corresponding to fractal type
mandelfn, and is the generalization of type lambda.

<snip>

Formula:  Initialize: z=pixel
          Iterate:    cfn(z),
                      where fn(z) is one of conj, cos, cosh, cosxx,
cotan, cotanh, exp, flip, ident, log, recip, sin, sinh, sqr, tan, tanh,
or zero.

Code:

Routine Type                   Routine Name             File

Fractal engine                 StandardFractal()        CALCFRACT.C
Integer math initialization    long_julia_per_pixel()   FRACTALS.C
Integer math orbit             LambdaTrigFractal()      FRACTALS.C
Floating point initialization  otherjuliafp_per_pixel() FRACTALS.C
Floating point orbit           LambdafpFractal()        FRACTALS.C


So, as I said, the lambdafn formula was written into the C-language
files that were compiled to make Fractint. You won't find it in any
default formula file.

You'll just have to regard it as the *sacrificial lambda*. 8-)

Now I'm going back to watch the rest of Monday Night Football.

Goodnight folks,

<

Repeating a bit what has already been said here, if you select the type and
then hit <z> you will see a brief explanation of the built in type. Also
hitting F1 in the menu selection screen will show the documentation's
explanation of the type.

The idea of writing formulas for the type "formula" feature of fractint
which are equivalent to the built in types has been posed as a challenge to
Fractint users several times over the years. It turns out that some are
easy to do, and others quite difficult. Formulas which were written in
answer to these challenges generally have the same name as the built in
type, and were collected in .frm files with the names Sylvie mentioned
(builtn.frm, builtn01.frm, and builtn2.frm; I think there also may have
been a file "parser.frm" which did the same thing). To see the built in
type "lambdafn", for example, you would look in the orgform compilation
files _l.frm and _l_dup.frm for formulas with the name "lambdafn". Hitting
F2 while the formula name is highlighted in the menu selection screen will
show you the text of the formula. You probably have someone's stab at
casting the built in type as a formula. If there is no formula in the
compilation with the same name as the built in type, it means that no one
has yet written a formula equivalent of the built in type.

You can collect all of the formulas in the orgform compilation which have a
common source into a single .frm file by using the /r switch. For example,
the following command

orgform builtn.frm /r

will cause orgform to search the entire compilation, and copy any formula
with a line ";SOURCE: builtn.frm" to a file reconstr.frm (successive runs
with this switch append the formulas to reconstr.frm, so you can collect
the formulas from several sources into this one file). A big caveat is
necessary here - the reconstructed file may not have all the formulas that
the original file had. This happens when a formula from a file was not
added to the orgform compilation because an identical version of the
formula was already in the compilation from another source. Also, inter
formula text is not copied into the orgform compilation, and will therefore
also will be missing from the reconstr.frm reconstruction of the file.

Hope this helps

Subject: (fractint) OT - Saving Win95 Text files as PAR
Date: 09 Sep 1997 09:20:00 -0400

Fractallistas,

I'm always humbled by the mathematical expertise, esthetic sense, and sheer
energy exhibited by those who are frequent posters to these lists.
Occasions to meaningfully contribute to the group dialog occur to me
infrequently at best so when I find something which makes my fractal
imaging easier I feel the need to share it with the group in the hope that
it will make someone else's efforts go a little smoother. Please forgive me
if this message is too far off topic.

Something that has bothered me (much like a fly that won't let one alone)
for several years was not being able to save a PAR file using Win95's
notepad without it adding a .txt extension to the name of the file, for
example name.par.txt. After saving about a month's worth of Jim Muth's
wonderful FOTD's to disk I'd have to go back and right click on the file
name and remove the .txt extension from a long list of files.

Last week I happened upon a Win95 Notepad replacement called Notepad+. In
it's documentation are a few tips which I've found invaluable:

- if you wish to keep Win95 from adding an extension to your filename
simply put the filename in quotes when you save it, for example
"a:\filename.par".

- if you want to make that change permanent go into Explorer's View Options
and click File Type, Add New File Type and in the dialog box that appears
put .PAR next to the associated extension and have it open with Notepad.
Then you will never have to remove the .txt extension from a .par file ever
again!

I highly recommend Notepad+. It is freeware (in the spirit of Fractint) and
allows one to open many text files at once. It is really good for editing
Web Pages. Notepad's rather small file size limitation is also addressed.
Notepad+ lets you open text files as large as 400K.

You can find Notepad+ at http://www.download.com. Search for Notepads+
(Note that the filename is Notepads+ with an 's'). There are 16 and 32 bit
versions of the software.

BTW, I learned a Win95 trick the other day that might be handy to
share with others.  You can add menu items to the context-sensitive
menu in Win95, customizing GIF file extensions to understand how to
work with fractint!

Here's how.  In an explorer window:

1. select the View / Options... menu item.
2. select the "file types" tab
3. select the entry in the list for GIF files
4. click edit
5. Add a new action:
    Name fractint
    Program (browse to your fractint.exe)
OK out of the dialogs

Now when you right button on a gif file, you should see a "fractint"
entry in the menu.  Selecting this runs fractint with the gif file as
an argument on the command line, loading the GIF file into fractint.

Me being the fanatic I am, I went and tried this right away! It worked, but
not until Fractint first whined about not having FRACTINT.CFG or some such
thing; I tried again, with a different one, and it did it again . . . Does
it do that to you, or did you not have that problem?

I have had some troubles with this too.  I think its a problem with
the way fractint searches for fractint.cfg; it seems to be searching
the current directory only and whining when it can't find it.  See if
putting the directory where fractint is located in the path in your
autoexec.bat and see if that stops the whining.

Subject: (fractint) large GIF problems
Date: 10 Sep 1997 23:45:50 -0600

Quite a while ago Jon Noring ran into a bug in the simplgif program
that comes with Fractint. This program combines the multiple image
GIFs that Fractint produces when making giant images. Jon sent me a
huge example that illustrated the bug, but a while ago I accidently
deleted it, and I don't believe Jon has it anymore either.

Similarly, Fractint's GIF encoder occasionally fails, usually on
images with very few colors, such as you might have when doing on
piece of a much larger image. We juggled the lzw parameters in
Fractint and all the existing examples of the bug were fixed, but we
had the definite feeling that we were only hiding the problem.

Does anyone have any example PAR files that generate images that
fractint cannot save properly, or that simplgif cannot handle?

Thanks. There's a replacement for simplgif (I forget the name, Jon
has mentioned it here), but we'd still like to squash the bug.
However, the bug in Fractint's encoder is more serious, because if
you run into it you won't be able to save the image. Examples will
help us track down these bugs.

Tim will no doubt have the final word on the yet-to-be-solved problems with
Fractint's Divide and Conquer method (D&C).  He's very familiar with them.

I've spent over three years learning how to reliably use D&C to produce very
large fractal images.  I now routinely produce images as large as 18432x13824
(using an 18x18 array of 1024x768) for making 8x10" Ektachrome transparencies
at 2032 d.p.i.

The road to do this (especially at large image sizes) is fraught with a few
pot holes.  For example, certain Fractint images won't save properly (those
with very simple banding which are often saved as part of D&C).  Many times
I have to use D&C at a very small scale to properly reproduce these pieces,
or I'll double the resolution and then use an image processing utility to
half the resolution (it's o.k. to use this method for those images with
simple banding).

Another problem which Tim knows about is a bug in Simplgif.  Sometimes it
just blows up, and as far as I know Tim has not yet found the bug.  Anyway,
I highly recommend a utility by Mr. Paasen in the Netherlands named "Image
Arithmetic" which is much more reliable, more flexible, and requires little
disk memory to run (with Simplgif and GIF Construction Set, to assemble the
18x18 array of 1024x768 images I'd have to have 1.2 *gigs* of free hard disk
space.  With "imageart", I only need enough space to hold the final
assembled image.)

There's a couple other fersnickety things about D&C as well, which maybe I'll
talk about in a future "tutorial" I'm thinking of writing.  But once you get
D&C working, the sky's the limit for image size.  I plan to soon tile a
28x28 array of 1024x768 image to make a 28672x21504 image for writing to
8x10" transparencies at 3048 dpi, near to the grain limits of the film --
unless I plan to make much larger transparencies or if the new direct-to-
print film technologies increase their write resolution, this is about as far
as one will ever need to go to make disply prints up to 50" in size, even
allowing for anti-aliasing at 2:1 reduction.

Subject: (fractint) Magnification
Date: 11 Sep 1997 15:52:12, -0500

Hi All

For the last twelve years I have hat a pet peeve, and it is using
magnification to define a picture. In order to use it you need a base. Way
back in August of 85 it got defined as the reciprocal of the length of a
side of the picture. Up to a point this serves, but at any resolution this
constant. A 1024X728 view and a 320X200 view are obviously radically
different in detail so we don't have empty magnification as occurs with a
microscope where beyond some point there is no more detail visable.
Fractint has the same problem where the height of the serves  as the reference.

I have used pixel size as the basic reference. The conversion is easy
enough. Dividing 2 by magnification gives pixel size, but with far more
apparent accuracy than needed. Four significant figures beyond a number of
zeros would let us size a 10Kx10K to within one pixel. There are a number
of advantages to this approach. Round off calculation errors would be
reduced, Pictures of multiple parts would have exactly known corner
coordinates, and scaling would be more precise. Who can appreciate a
magnification given to 17 places?

I know that this is a too deeply ingrained convention to be replaced but
lets have a choice.

I'm having a slightly different problem than the above.  I can get Fractint
to run on my PPro 180 with 32 MB RAM, but when I try to save the image, the
lines  that appear on the side to show the progress of the save end up
repeating the first few lines after a certain point.  When I open a DOS
prompt, not necessarily restarting in DOS mode, Fractint works fine.  Does
anybody have any idea why this is?

Hello,

Yesterday I had occasion to use FractInt in a rather unconventional
fashion.  A friend of mine had several monitors he was working on, and he
wanted to be able to display a color test pattern on them so he could
adjust the monitor settings appropriately.  But he didn't have anything
handy that would do the job, let along in different display modes.

FractInt to the rescue! :)  I wrote a quick formula to display some color
bars on the screen, tweaked the FRACTINT.CFG and SSTOOLS.INI file to come
up with that by default, in just the mode he wanted, and sent it off to him.

He's ecstatic.  Perhaps one of these days he'll try hitting keys and figure
out what FractInt is REALLY all about. :)

prompt, not necessarily restarting in DOS mode, Fractint works fine.  =
Does
anybody have any idea why this is?

Subject: (fractint) Truecolor bug...
Date: 14 Sep 1997 12:38:03 -0600 (MDT)

Howdy folks...

    With Damien's help, I am making reasonable progress on my code to
allow unattended zooming into the M-set.  I've decided to use Fractint's
truecolor=yes option to produce a Targa file with the iteration values in
it, rather than try to derive relative iteration values from a GIF
image.  My intent was to produce an image with viewwindows=yes, at about
50x38 pixels, and save that image as iterates.tga.  I want an image size
of about 50x38 for two reasons: (a) the images will take less time to
render (very important for deepzooms), and (b) there are memory
requirement problems when I try to declare a 320x200 array on my PC.
The problem is that it appears the iterates.tga file is corrupted if
viewwindows is on (thanks again to Damien!).

    Problem b) can be jury-rigged by only reading in every other
pixel in every other row, resulting an a final array 1/4 the size of te
original.  Problem a) is more of a cosmetic problem, but will become a
big deal when we get fairly deep.

    So I guess I'll work around these problems for now, but wht is the
chances of the bug getting fixed, so that we can save truecolor images
with viewwindows on?

                        Thanks all, Jason

Date: 14 Sep 1997 16:30:45 -0400 (EDT)

Hello everyone.

I've been using fractint for Windows for a short period of time now and have
found it to be a phenomenal program.

I'm at the experimental phase now, though, and am trying to find a way to
customize the colors that Fractint chooses to use for escape-time fractals.

Do I have to program in these new variables?  If so, How?

Since I am not a programming wiz, would it be better to seek out other color
maps that have already been written in the hopes that I will get the desired
hues?   If so, can you suggest the best place to begin my search?

Thanx.

I've found and fixed this. The workaround for now is to make a
diskvideo mode the size you want, and not using viewwindows. In the
next version this will be fixed.

If anyone else has this problem let me know.

Regarding running fractint under Windows NT 4.0 with a Matrox Millennium
(or other cards) in SVGA modes:

During the last 3 weeks I have sent two messages to Matrox tech support and
a message to tech support at the company who build my system and I have not
received any reply. However, I did find the following recent document on
Microsoft's Knowledge Base. Here is the complete text. Read it and weep.

---------------Start Q155259
VESA Drivers Not Supported in a VDM

Last reviewed: August 13, 1997
Article ID: Q155259

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0

SUMMARY

When you attempt to load a VESA video driver in a Virtual DOS Machine
(VDM), the driver either fails to load or does not work properly.

MORE INFORMATION

Windows NT does not support loading VESA video drivers in a VDM. Even
though some VESA video drivers may load properly and seem to funtion
correctly in a VDM, this is not recommended.

Windows NT by design denies direct access to the hardware to all programs.
Any program that tries to use direct hardware calls will fail in Windows NT.
---------------End Q155259

Well, this does not look good, although it doesn't make any sense to me.
Like I said in previous messages, I am not getting an error message from
NT, but rather a message from my monitor saying that the synch freq is out
of range. Why would NT cause the video card to send the wrong synch freq?
Tim, did you ever ask Bert Tyler about this? If anyone else has any further
information, please share it with us.

Hope this helps,
Nick

--=====================_874539128==_
Content-Type: text/plain; charset="us-ascii"

Howdy folks,

Attached to this message is a formula file containing all the new coloring
algorithms I have made for FractInt, for both the Mandelbrot set and the
NovaM fractal.  Many of these are variations on orbit trap types; a few are
based on formulae Kerry Mitchell posted here recently.  There are over 100
different formulae in this file.  Details as to what each formula does are
contained in the "dmj--Read-Me-First" formula which will be the first one
listed.  Although I have only provided versions of the algorithms for
Mandelbrot and NovaM types, instructions are included on how to adapt the
techniques to other types.  Each formula is extensively commented as well.

Lee Skinner asked for example PARs to show some of what is possible.  I
have forty or so images produced with these formulae (and a few other
formulae that aren't ready for "prime time") so I don't really want to post
PARs for all of them here.  I hope to have most of them up on my web
gallery later today.  Here are six, though, to show you what is possible
with these techniques:

Sorry for the lame header - the mail program does it :(

 Well, hello to everybody. This is my first time to send a mail to this list
 - I hope You won't mind my beginner questions!

 Basically my problem is not with Fractint, but making fractal calculations
faster.
 I worked with Mandelbrot fractals for about 2 months. As I work on
Commodore 64 (1 Mhz) the calculation time is very important - so if You have
any good ideas to speed up Mandelbrot calculations, please let me know!

 My ideas were:

 -Use 2 bytes for numbers (1 bit negative flag, 3 bits for whole, 12 bits for
decimal) Ofcourse 2 complements.

 -Give the iteration counter maximum a little value (f.e. 10)

 -I don't know the special name for this stuff: the maximum distance of the
moving point {  sqrt(x*x+y*y)>=maxdistance   }. Well, I used no squareroot
function, I calculated the distance and compared oit with the maxdistance
squared (maxdistance was 2)

 Yes, I think these were the basic improvements (only :( ). There were some
more like coding the multiplier routine faster (the C64 has no inbuilt
command like MUL), etc.

 There MUST be other ways of speeding up the routine, coz I saw fullscreen
(160x200) REALTIME mandelbrot fractals calculated in 4 seconds...

 Anyway, thank you for your help, and please forgive my bad english and poor
sentences, but I'm in the middle of a MS-Works lesson and I could not
concentrate perfectly.

Best wishes: Andras P.Toth (Hungary)

Both McAfee and Norton produce capable virus scan programs. I personally use
McAfee since we bought a site licence here at work. Their web site is:

http://www.mcafee.com

But don't get too paranoid. I've had access to the internet (in its various
shapes and forms) for over 10 years, and I have _never_ encountered a virus.
I worked with someone who would scream "VIRUS" at least once a week. In every
case, it turned out that, with his limited computer abilities, he either didn't
know how to run a particular program, or he had his system so twisted in a
knot (messed up or missing configuration files, misplaced files, incomplete
installation) that nothing would work.

Subject: (fractint) Using FractInt with an Imagine 128...
Date: 17 Sep 1997 18:39:54 -0500

Hello everyone!

This is my first posting to the FractInt list and I am wondering if
anybody on the list uses an Imagine 128 (mine has 4 meg of ram) to draw
their fractals?  It seems that the chipset on the card only allows for
512k in DOS which doesn't allow for very good resolution!  I've been
told that I need a DOS VESA driver so if anybody could help me I'd
appreciate it!  I have a 21" Viewsonic PS and am really looking forward
to finding some incredible images!

If it turns out that this card is pretty bogus for drawing fractals, I'd
entertain upgrading to a new video card.  I am wondering if 3D
accelerators also can provide a benefit with the FractInt program.  I've
had this Imagine 128 for about two years so I am kinda in need for an
upgrade anyway!  What would be the ultimate card for drawing with a
Pentium system?  I also use Win95 for games and Netscape so the card
would have to work with this as well.

Looking forward to any replies!

Sincerely,

Tim Maxwell

Date: 17 Sep 1997 19:15:23 -0500

I would love to know if there is a fix for a bug that crept into Fractint DOS
after ver 14 or 15 (the one that shipped with the Waite Press Fractint book).
Prior to this bug, the L-System 'ColorSnowflake' would generate symmetrical
images at levels at least as high as 8. Since then, any value over 5 results in
a warped, asymetrical image being generated.

This bug has performed on all machines I have ever tested it on.

Any thoughts? If nescessary, I would even be willing to load a pre-bug version
of Fractint just to access this one formula. It's easily my favorite 'fractal'.

A forms page is provided on my sites for viewers to submit by email to
me random numbers and functions. I then draw an image in Fractint based on these
parameters using (I hope) interesting formulas, affix the submitter's name,
then post the image to my site. The viewers love it and I love the
action and the challange. I call these fractals U-draws.

My U-draw sites are:

Mr. Bluestein has a point here.  Both the "Snowflake2" and "SnowflakeColor"
L-system types go haywire on levels 5 and above.   On level 5, the first few
mini-snowflakes are drawn OK, but then it seems the program realizes that the
entire snowflake won't fit on the screen and scales the remaining segments to fit,
with disasterous results.  Level 6 is so screwed up that only the first largest
sub-snowflake (which, by the way, IS the level 5 snowflake) is entirely on the
screen.  Correct me if I'm wrong, but isn't the whole thing supposed to be on the
screen?  If anyone out there has any ideas on this, such as what might be wrong or
how to fix it, send 'em in!

Subject: (fractint) L-System Fractal Wanted!
Date: 17 Sep 1997 21:17:40 -0500

Ever since I've seen the "Twin Dragon Skin" fractal described in Benoit
B. Mandelbrot's book, "The Fractal Geometry of Nature", I've wanted to
see what it looked like.  So far, it hasn't appeared in any book that I
checked in iterated form, only in generator form.  I was hoping it would
be included in the L-system fractals, but alas! No such luck! So, if
anyone out there has a formula file for this or (horror of horrors!) can
tell me how to do it myself, I would greatly appreciate it! Thanks!

I have known about this bug for years, but your raising it again
cast some light. The bug does not appear in 16.11 but does appear in
17.2. In between those versions assembler speedup code was added.
Generally in Fractint the debug=90 option disables assembler and uses
the C code, but this doesn't work for lsys as near as I can tell, so
the C code is not used.

On a hunch I tried the Xfractint version, which of course does not
use the assembler. The snowflakecolor fractal was OK at level 6. This
suggests that the assembler is where the bug is.

I'll investigate adding a switch to use the C code in the DOS
version. I've mentioned this to Adrian mariano, the assembler author,
but I haven't heard from him in a while.

Tim

Like the excerpt from Microsoft states, NT does not like programs
directly talking to the hardware; the hardware abstraction layer is
talked to instead.  This means all the great SVGA detection logic in
fractint can't work properly.  I tried using fractint under NT before,
and none of the higher resolution modes were available, and some of the
modes had interesting side effects.  I don't recomend using DOS fractint
under NT.  NT is a good operating system, and fractint is a good
program, but they don't cooperate very well.  I recomend either using
the dual boot in NT to boot to DOS (if you have a copy of it), or using
the (oh no) windows port of fractint.

Fixed point math. (The C-64 uses 2's complement? kewl. I don't remember
much about my old C-64, except that signed char was from -128 to 127,
consistent with bias-128 or 2's...) For deeper zooms try 4 bytes, 1 sign
bit, 3 bits point 28. For types other than mandelbrot you have problems if
the set is bigger than +/-7. There goes continuous potential, labmda-cos
z, etc.
(Did the C-64 have an FPU? If not how come BASIC could deal with float
types? Emulation?)

> -Give the iteration counter maximum a little value (f.e. 10)

10? That'll give you a triangular black blob and a few bands of color :P
Any decent Mandelbrotting requires it to be at least a small int. Try an
unsigned int, 2 bytes 0-65535. (Gets slow for high iters of course.)

That will save some cycles. (Watch out for overflow. Don't forget if the
real or imag parts goes above 7 or below -8 it will wrap with your fixed
point numbers.)

Gak! I remember that. No MUL! Yack. I coded a 64-bit fixed point mult...
in asm... never actually tried to run the darn thing. Afraid of the result
probably. :)

> There MUST be other ways of speeding up the routine, coz I saw fullscreen

160x200...gak! That was the biggest mode wasn't it...160x200x16. eeeuw.
Nowadays if you catch a vid card that won't do 320x240x256 you throw it
back and try again.

Subject: (fractint) video modes
Date: 18 Sep 1997 17:37:30 -0400

The following questions are not directly related to fractals or
Fractint, but they are at least motivated solely by my desire to
maximize my ability to generate fractals at the highest possible
resolution.  If I am not mistaken, such questions were invited in the
introduction to this mailing list. I am woefully ignorant about some
things.  In particular, I am somewhat embarrassed to say, I am not
completely clear about the difference between video upgrade kits, video
drivers, and video cards.  I have a NEC Ready 9710 machine (166 Mhz
Pentium MMX; 16MB RAM; 2MB video RAM).  My manual says that a video
upgrade kit is available to raise video memory to 4MB, but I suspect
that there are ways to go beyond that by addition of cards, drivers,
etc.  Is that correct?  I cannot get any useful information from the
manufacturer.  The best reply I was able to get from them, despite the
praises lavished on their support services by the salesman who sold me
the computer, repeated verbatim what is stated in my printed user's
manual, and nothing more.  At present I am using Fractint in SF7  video
mode (1024x768x256), but would like to be able to display higher
resolution images on my screen, as well as be prepared for the time when
Fractint will be available in true color.  I would greatly appreciate
any suggestions either directly, or by reference to a source where I
could get such information.  May I add that I am tremendously grateful
to the Stone Soup Group for providing such a wonderful thing as
Fractint.  (I only discovered this mailing list a couple of days ago and
this is my first posted message.)  Thanks, Gedeon Peteri.

Howdy folks,

Those of you who subscribe to the digest will not have received the FRM
file I attached to a message.  Should you wish a copy, I will post one soon
on my web site (and I'll post a note here when I do so, sometime tomorrow
it seems).  Anyone who can't wait that long :-) should e-mail me and I'll
send it out right away.

I did not post the file uncompressed because it's huge, but compresses
*very* well into a 7K ZIP.

Hello Gedeon,

Here is some info on video cards that may help:

> The video modes you can display are directly related to the amount of
video memory,
For example, a card with 2Mb can display the following modes:
640x480x256
800x600x256
1024x768x256
1280x1024x256
640x480x65536 (high color)
800x600x65536 (high color)
1024x768x65536 (high color)
1152x864x65536 (high color)
640x480x16million (true color)
800x600x16million (true color)

A 4Mb card can also display:
1024x768x16million
1152x864x16million (this is my favorite mode for 17 inch monitors)
1280x1024x16million
1600x1200x256 (This mode may work with 2Mb ??)
1600x1200x65536

8Mb is needed for 1600x1200x16million

The driver cannot change this situation. If you want the 4Mb modes, you
must get the 4Mb upgrade or buy a new video card with 4Mb. There are some
differences among drivers for different video cards, however. Some do not
support 1152x864 or 1600x1200 at all.

> Your monitor must also be able to support the resolution you want. Number
of colors is not an issue, but some monitors cannot handle 1600x1200.

> Most recent DOS programs do not need video drivers because most modern
cards and DOS programs support the VESA standard. VESA support may be built
into the video card's BIOS or you may have to load a small DOS TSR. Most
(but not all) of the above modes are supported by VESA. All those other
video modes you see in fractint are left over from the days before VESA.

> You do need a video driver for Windows, but of course all video cards
come with one. However, it pays to check manufacturer's web site for
updates. Windows video drivers are notoriously buggy and are the cause of
many Windows crashes and problems. The drivers are often updated frequently.

I hope this helps somewhat. If you have any more questions, please post
them or you can email me directly.

Subject: Re: (fractint) video modes
Date: 19 Sep 1997 15:09:57 -0400

Nick, Gedeon,

1600x1200x256 is doable on my 2M graphics card.  In general, I've been
pretty happy with this amount of RAM on the card, since 1600x1200 is about
the highest mode my monitor can display anyway.

I would also note that some video cards will accomodate "odd" RAM sizes.
For example, I once worked with a Number Nine GXE something-or-other that
had 3M of RAM on it.  This allowed a mode like 1024x768x16M which doesn't
quite fit in 2M.

You can calculate the amount of RAM needed for a mode by simply multiplying
the width by the height by the bit depth and dividing by eight.  For example:

640 x 480 x 8 (256 colors) / 8 = 307200 (fits in 512K)
800 x 600 x 16 (65K colors) / 8 = 960000 (just fits in 1M)
1024 x 768 x 24 (16M colors) / 8 = 2359296 (doesn't fit in 2M)
800 x 600 x 32 (16M colors) / 8 = 1920000 (just fits in 2M)

You'll notice in the above examples that I list both 24-bit and 32-bit as
being 16M color modes.  A 32-bit mode wastes eight bits of each pixel, but
because 32-bit values are easier (and faster) for computers to deal with
than 24-bit values, many graphics cards go ahead and waste the RAM to
provide increased performance.  Some cards do not support true 24-bit
modes, but always use 32-bit modes instead.

How do you tell which 16M mode your card is using?  In Windows, it's pretty
easy: right-click a blank area of your desktop, choose "Properties", switch
to the "Settings" tab, and in the "Color palette" drop-down, you should see
the actual bit depth listed.  Typically you can choose between 8-bit,
16-bit, 24-bit, and 32-bit.  Just remember that visually, 24-bit and 32-bit
will be the same, but 32-bit modes will have higher performance.

Unless you're doing serious graphics work, I'd recommend using a 16-bit
mode.  Performance here is even better than 32-bit modes, and it seems the
best trade-off between performance and color quality.  Web browsing in
8-bit modes (256-color) is rather grainy, as all that pretty color (which
you're downloading whether you see the quality or not) is wasted.  At the
moment, bit depth beyond 8 doesn't do anything for FractInt, but when you
run FractInt from Windows it will change the display mode anyway.

Just my ramblings...

    Nick, Damien,
    Many thanks for the highly informative letters.  Since the maximum
resolution my monitor will support is 1280x1024, it appears that I am
already set for this with my 2MB of video RAM.  Simply adding the update
kit to 4MB would enable me to use 1600x1200 with present Fractint - 256
colors.  Only if Fractint went to true color (16 million) would I need
8MB to support the 1600x1200 resolution.  Am I correct to draw these
conclusions?  If so, though going for 8MB does not make any sense at
this time for me, I am nonetheless curious whether an 8MB video card
could be installed in my computer?  In other words, does the fact that
the manual only mentions upgrading to 4MB mean that there are other
system components (excluding the monitor) which could not support more
than that, or does it not?

The Mandelbrot set use this iteration formula:

z := z^2 + c;

where z is initally zero.

We color pixels corresponding to the value of c according to the
number of iterations, n, it takes to have |z|>2.  If n gets beyond
itermax we set the color to black, usually.

You control what part of the Mandelbrot set you see by how
you map c to the screen.  You use some interpolation formula
like

c(real) = c(left side) + column*deltac
c(imag)=c(top)-row*deltac


So your initial parameters are c(left side), c(top), deltac or an
equivalent set like the center c and magnification.

Hope this helps.


Jay

According to Damien, you only need 2Mb for 1600x1200x256 (thanks for
posting that formula Damien; I had forgotten it). Too bad your monitor
doesn't support it. This is my favorite mode for fractint.

Yes, that is correct. Unless, of course, you want to run other programs at
that resolution.

It only means that the video board that came with your system only supports
4MB. But you could replace that video board with another one (or if it is
built into the motherboard, you can disable it). I was just on Matrox's web
site and their new Millenium II comes with either 4Mb, 8Mb, or 16Mb! They
just lowered the price too. It is about $200 (US) for the 4Mb version. This
is a very good price!

Hi.
Could someone please tell me what anti-aliasing means? I am under the
impression it has something to do with creating high-rez images and then
bringing them back down to a smaller size. I do this because they look
better than when I just create them at the smaller size, unless my eyes
deceive  me. Anyway, I am curious what people mean when they say they are
doing such and such a thing to their images for anti-aliasing.

                    Thanks,

Peter,

Assuming you don't want a technical answer (which would only barely not be
over my head :) you can think of anti-aliasing as a way to smooth out rapid
transitions in an image.  Think of the highly detailed "mush" areas of a
fractal image--those areas would show more detail zoomed in, possibly even
resolving into structures you could see, but in your image they're just
"mush".  Well, anti-aliasing typically involves generating the image at a
higher resolution, to go ahead and resolve those areas... and then the
image is reduced in a graphics package, which averages several pixels down
into each pixel in the smaller image, giving the "overall" color.

This is a pretty bad explanation, but no doubt someone else will step in
and take the time to do it right. :)

Gedeon,

Your card should be able to do 1600x1200x256 with the 2M you currently
have.  You should also be aware that quite a few graphics cards will do a
1600x1200 VESA mode as interlaced, so your monitor only needs to be able to
handle half the vertical resolution (600).  Your monitor easily does this.
You'll just want to make sure you use the VESA modes in FractInt (which
work best under Win95 anyway).

Your *computer* will take an 8M graphics card fine.  Whether or not your
graphics card will take an 8M *upgrade* is another issue--one that only
your graphics card manufacturer can answer.  And it's solely dependent on
the graphics card; nothing in the computer or monitor affects this.

Tim,

 - Well I have let my post go for a few days concerning the Imagine 128 and
 - I guess nobody uses one.

Well, I don't have one, didn't get one because some 64-bit cards were still
faster than the Imagine 128.  Seemed at the time that Number Nine was just
going for the "bigger is better" approach. :(

 - If you had the oppertunity to get a new video card for drawing fractals,
 - what would it be?

Well, that depends on whether you've got a system that can take PCI cards
or not.  I hope you do, because that makes it easy: any modern card will
do.  You'll be hard-pressed to find a new card with less than 2M, which as
I've described is more than adequate for all but the most die-hard FractInt
fanatics with 21" monitors.  (And oh, would I love to join the ranks of
those fanatics! :)  So buy your next graphics card, not for what it can do
for FractInt, but for what *else* it can do.  Personally, I'd lean towards
something with decent 3D acceleration, preferably with a Voodoo chipset
from 3Dfx, for awesome Quake/Hexen performance, but that's just me. :)

 - I am also wondering if 3D accelerators can help in drawing any types of
 - fractals.

Not in FractInt.  The only thing a 3D accelerator might help would be 3D
rendering of fractals, but keep in mind that 3D cards are typically
designed with real-time (read: low-quality) performance in mind.  If you're
generating images thirty times a second, you don't typically care that it's
not doing filtered interpolation with Phong-rendered highlights and proper
shadows... but if you're rendering a still image that people are going to
be gazing at for a long time to come, you want to make sure that it's done
right, because you may not get the chance to do it over.  3D cards don't
always accelerate final renders (depends on the renderer) but they can
certainly help out interactive editing of 3D objects.  But again, not in
FractInt as it currently stands.

 - Any input would be appreciated as I've decided to upgrade my system
 - now.  The Imagine128 doesn't work with the new DirectX drivers for
 - windows games anyway...

*Lots* of stuff doesn't work with DirectX yet.  My sound card, a Gravis
Ultrasound, has such lousy driver support that DirectX crashes most things
that try to use it.  That's why when I re-installed everything a couple of
months ago, I didn't install DirectX.  'Course, none of this is
FractInt-related... :)

anti-aliasing

<graphics> A technique used on a grey-scale or colour bitmap display
to make diagonal edges appear smoother by setting pixels near the edge
to intermediate colours according to where the edge crosses them.

The most common example is black characters on a white background.
Without anti-aliasing, diagonal edges appear jagged, like staircases,
which may be noticeable on a low resolution display. If the display
can show intermediate greys then anti-aliasing can be applied. A pixel
will be black if it is completely within the black area, or white if it
is completely outside the black area, or an intermediate shade of grey
according to the proportions of it which overlap the black and white
areas. The technique works similarly with other foreground and
background colours.

In a lot of graphic applications (like Adobe Photoshop), anti-aliasing
produces a smooth-edged selection by partially filling edge pixels so
that they are semitransparent.  Because anti-aliasing removes jagged
edges, it is especially useful when you=92re creating composite images by=

cutting and pasting.  No detail is lost, since only the edge pixels
change.

Anti-aliasing is a method of smoothing the edges of shapes, objects, and
mask selections.  Anti-aliasing creates intermediate pixels that smooth
the transition between colors and sharp edges.  To produce a curved or
diagonal edge on a selection, pixels in the image that are diagonal to
each other are part of the selection=92s edge.  This diagonal pixel
selection can produce a jagged edge.  Anti-aliasing makes some of the
pixels located along the inside edge of the selection semi-transparent
which smoothes out the edges of the selection.

Smoothing the jaggies in a bitmapped image. When diagonal or curved
lines are put in bitmapped form, these shapes must be made with square
pixels; any lines that are not vertical or horizontal have a
stair-stepped appearance. Anti-aliasing changes the pixels along the
edges of the line into varying shades of gray or in-between color, in
order to make the edge appear smoother. In a black-on-white image, for
example, the shade of gray used is determined by how much of the
in-between pixel overlaps the black area and how much overlaps the
white area.

[engage "bad explanation" mode :-) ]

The term "anti-aliasing" is most probably a throw-back to signal analysis,
and what happens when you take discrete samples of a continuous signal.
Essentially, if you think of a signal as a series of sine waves with
different frequencies superimposed, then you can only resolve certain
frequencies, dependent on your sampling frequency.  Frequencies higher
than the cutoff ("Nyquist frequency") get folded over and are seen as
lower frequencies.  Thus, the higer modes are "aliased" as lower modes.
So, anti-aliasing is a way to prevent this from happening--you filter your
incoming signal to remove the frequencies higher than the cutoff, then
sample it.

There are parallels to fractalizing.  The pixels of a fractal image
represent discrete samples of a continuous signal (mathematically pure
fractal).  The "jaggies" and "mush" that we commonly see are high
frequency (high spatial frequency = small, pixelwise) structures that are
sampled too poorly to be resolved.  In other words, the swirls and
midgets are too small to be captured by a "reasonable" number of pixels,
so they look like "mush" or visual noise.  Instead of pre-filtering the
fractal, we compute it at a higher resolution and average it down to a
lower resolution.  This has the effect of smoothing over the higher
frequencies, while leaving the lower ones (big structures) basically
untouched.

How's that?

The less serious is that the collection of 2 and 16-color modes at the

Anti-aliasing is also used to get rid of Moire patterns, such as you see
if you raytrace a black green-gridded floor or one with green parallel
lines converging in the distance. Similarly for averaging out "busy" areas
of pictures. :)

One way I could think of, off the top of my head, would be to <s>ave your
fractal as a .gif file, and then printing it with your basic .gif viewer,
say your favorite Web Browser.  Just a thought.

I would forget all about trying to print directly from fractint.
Instead you should save you images in their native .gif format and then u=

a graphics package to print these. If you are running Windows, then I wou=

suggest starting with the shareware program "Paint Shop Pro" - it won't
cost you anything to try it!

For me, the most important key to getting a good looking print is to crea=

your images at very high resolutions. You could even use one of the
"disk/ram" video modes and save those images directly to disk. For *reall=
y*
big fractals you could use the "divide and conquer" method for creating
very large images in pieces (refer to fractint.doc).

As a rule of thumb, think of the dots from your printer as pixels in the
image. So, if you print a 10"x8" image at 300dpi, you could start with a
gif having dimensions of (10x300) x (8x300) or 3000x2400. If this seems a=

bit "over the top", then try printing from a 1600x1200 image for starters=

I can't duplicate either problem.

Your fractint.cfg file is corrupt. Try replacing it with the one in
the 19.6 distribution.

This is absolutely good advice. The fractint authors know very little
about printing, and have access to few printers. We can't even test
the printer drivers that are donated to our code. However, all is not
lost. There are many excellent programs that print GIFs, so the best
bet is simply to save the GIF and print it in other software.

When we have a windows port this problem will go away, but the DOS
version will always be print challenged. If Fractint were commercial,
we could simply my a library of printer drivers. But since Fractint
is free and we publish the source, we can't do that.

Tim

(This is absolutely good advice.) [Tim Wegner]

Mentioned this once: I have found it best to save the .gif to be printed.
It can then be imported into a word processing document such as
WordPerfect, Adobe Pagemaker, etc. by cut and paste or copy and paste.
After importing it the image may then be resized (if desired) for various
applications, such as a unique "logo" on stationery, for making a unique
greeting card, for address labels, envelopes, or even printing on transfer
paper to be transferred to "T" shirts, etc.

Depending on the graphics program .gifs are associated with in whatever
specific computer such as PaintShopPro, LViewPro, etc., other images can be
inserted into the fractal .gif (resized if necessary). That can make for
some unusual effects also...   :) or special effects can be added. This
last just as an added after-thought.

 I tried your formula with the PARs you posted about a week ago, this
 afternoon, and I must admit they're among the most beautiful fractals
 I ever seen!
 Thanks a lot!  :)

My fractint.cfg file is exactly the one that came with Fractint,
unmodified. To be exact it is the one from the .zip located at Spanky. Did
you try the Spanky .zip instead of your development version?

Assuming you have a PCI system, I recommend the Matrox Millennium II. They
have lowered the price to about $200 US for the 4Mb card. I have the
original Millennium and am quite happy with it. I run it under DOS, OS/2,
and Windows NT and have had almost no problems. It is fast and handles just
about everything I throw at it. It is also fast for DOS games. Some video
cards are fast under Windows, but are slow under DOS (this does not apply
to fractint however - see below).

>I am also wondering if 3D accelerators can help in drawing any types of
fractals.

To repeat what Damien said: No. First of all, I don't think 3D accelerators
apply to DOS programs at all. Secondly, 99% of the time it takes to create
a fractal is the mathematical computation. The time it takes your video
card to display it on the screen is nothing compared to this. As I
understand it, 3D acceleration is for moving objects around the screen,
i.e., moving 3D objects in an animation or a game, so I don't think this
would help a Windows fractal program (unless it spun the fractal around the
screen <g>).

I've run a few programs that use DirectX and they work OK but I haven't
tried any of the fancy new games. DirectX is build into Windows NT 4.0. You
don't have to install it separately as in Win 95.

Hope this helps.

Subject: (fractint) Much older versions of Fractint!
Date: 22 Sep 1997 09:36:18 -0700 (PDT)

Hello,

For the fun of it, I performed a fairly extensive and exhaustive Web and ftp
search out there in Internetland to see what older versions of Fractint for
DOS are still downloadable (I was only interested in the distributable DOS
executable package -- not the source code).  Here's what I found so far, which
I've downloaded and archived for posterity:

      7.0
      8.1
     12.0
     14.0
     15.1
     16.0
     16.11
     17.01
     17.1
     17.2
     18.0
     18.1
     18.2
     19.0
     19.1
     19.2
     19.3
     19.4
     19.5
     19.6


Version 7.0 is a very old version, and running it certainly gives a good feel
for how far Fractint has come since then!

I would like to complete the collection, so if you have other versions,
especially the older ones (the Holy Grail would be version 1.0 and any pre-
1.0 betas -- Tim, can you give some early history to Fractint and the
versions?), please send them my way.  If there's enough interest, and Tim
doesn't mind, I can place Fractint version 7.0 at my ftp site for download.
And if I get close to a complete collection, I'll consider making it all
available via anonymous ftp for a short time.  We must remember our roots!

Hi Robert,

What kind of problems are you having?  Are you are referring to the recent
thread about fractint and other DOS VESA programs not running under NT? It
appears that this is the fault of NT and not the card. Microsoft states
that NT 4.0 does *not* support VESA in a DOS session. All the VESA modes
work fine in a DOS session under OS/2, so I would tend not to blame the
card. I have had no other problems under NT. However, their tech support
leaves a lot to be desired since they never answered my email.

I'm still not able to get my fractint up and running. Currently believing

Hey gang

For those who asked, I personally run Win95 on my machine for games and
using Netscape.  I found out that my Imagine 128 only uses 512k in DOS
so that's why I was having difficulty getting any decent resolution.
I've been talking to Number Nine tech support and they referred me to
this Scitech Software program called the Display Doctor 5.3a, but even
this program refuses to do anything for this card.

The Imagine 128 also doesn't support anything higher than DirectX 1.0
and I just bought a game with DirectX5 on it.  So I am definitely
looking into upgrading my system now.  I am hearing good things about
the Millenium II from this list and the Diamond FireGL from some other
friends.  I plan to make a move here very soon, so if you haven't put in
your two cents I am urging you too!

I used to have NT on my system but when I found out how much it hates
Windows games I killed it.  I can also issue a fair warning against
buying Xcar for you racing sim enthusiasts, it is just terrible, save
your money and wait for Need4Speed2 SE which is coming out soon.

Hey I am wondering how can I verify if my system has PCI slots?  What do
they look like?

Again, thanks in advance

    On one of my disks recently I found a copy of FRACT386...the
original...I packed it, and moved, if you want, remind me in a
month or so, and I will see if I can find it after I unpack.

    Back then, I was techsupport/sales at a computer store in
Toronto, and we sold more ATI VGA Wonder/NEC Multisync because of
the fractals we were displaying...

Good God man! Don't wait a month! Floppy disks have a habit of quitting
working suddenly and for no reason when they sit unused for a long time. I
sometimes wonder if the Disk Companies don't put little
planned-obsolescence gadgets in them that start ticking down as soon as you
first format or use the disk, and scrog a cluster a week from that point
forth... so you have to keep buying more...

Upload it to someplace on the net...and preserve this treasure of
antiquity...before it's too late! :-)

Yes, I got the files.  I checked them out, and IMHO, they actually do
resemble
the border of the twindragon curve,  except that the resulting curve is
actually
like one straight segment of the border of the twindragon instead of
being the
entire closed border.  I've tried to manipulate the L-system version to
make
it close, but it is difficult when I don't acually have the picture of
the
original twindragon in front of me. <g>  Anyway, if I can get it to
work, I'll
post it and anyone else who has any interest can check it out for
themselves.
Thanks for your help.

Tim,

 - I've been talking to Number Nine tech support and they referred me to
 - this Scitech Software program called the Display Doctor 5.3a, but even
 - this program refuses to do anything for this card.

If SciTech's software won't work with your card, then it's *really*
orphaned. :)  For the record, when we wanted to use the Number Nine GXE
card with Windows 95, Number Nine said they had no plans to write proper
drivers for it, that they were no longer supporting the card.  They offered
us an upgrade "deal", whereby we could send in the GXE and some money and
they'd send us a new card they did support.  Problem was, the upgrade price
was more than we could buy the new card for!  What a rip!  This experience
really soured us on Number Nine.

 - The Imagine 128 also doesn't support anything higher than DirectX 1.0
 - and I just bought a game with DirectX5 on it.  So I am definitely
 - looking into upgrading my system now.  I am hearing good things about
 - the Millenium II from this list and the Diamond FireGL from some other
 - friends.  I plan to make a move here very soon, so if you haven't put in
 - your two cents I am urging you too!

The Millenium isn't really the best optimized 3D card.  It's not going to
be your best performer for games.  I think the Mystique will do better if
you're set on a Matrox card--however, your best bet for *games* is likely
to be, as I said earlier, something with a 3Dfx chip on it.  Diamond
Monster 3D is a $200 add-on card that works with another graphics card to
give you awesome 3D, but I think what you really need is a good all-in-one
card.  A friend of mine recently bought a Hercules Stingray, which he is
*very* happy with.

 - Hey I am wondering how can I verify if my system has PCI slots?  What do
 - they look like?

PCI slots are short (shorter than ISA and much shorter than VESA LocalBus)
and usually white, with very fine pin spacing.

Subject: (fractint) New coloring scheme
Date: 24 Sep 1997 09:49:22 -0700 (MST)

Here is another coloring scheme that I found interesting.  It is based on
Gaussian integers--complex numbers whose real and imaginary parts are both
integers, like 3+4i.  The method here colors by which Gaussian integer the
iteration comes closest to.  In order to have a lot of iterations to test,
use a high bailout (like 1e012).  To show the results, use "decomp=256"
coloring.

Enclosed are two sample (Fractint) parameter files to demonstrate.  They
both use the same color map and the same section of the same Julia set.
The "plain" par shows the fractal as somewhat boring.  Turn on
decomposition (the "decomp" par) and see the explosion of color.  The
image is full of various sized dots of color.  Consequently, this method
benefits from "passes=1" instead of solid guessing, and it really helps to
anti-alias the final image, to smooth out the smallest dots.  I will post
a version of "decomp" to the fractal binaries newsgroup.

Enjoy!

Sorry for the lame header again....

 Thank you for your answers about fast mandelbrot calculations.

 This time I have another beginner problem - (probably my maths are not
enough to understand fractal algorithms?? Anyway, I'm just 16, so sorry
about this!)
 My major problem is with generating IFS fractals. In Fractint (and on
several WebSites) I found a a matrix with seven values, but I don't know
what to do with it...
 Probably I should display the moving point just like in Mandelbrot, but
displaying it after every calculation? And what are the starting values...
etc. Questions like this... SO if you have any kind of Pascal/C/C64
assembler :) sources then please let me know the location of them!

 Thank you, and sorry for being so beginner :)

Fractals are simple systems which give rise to complex behavior.  To
make a fractal image, you take a simple computation and repeat it and
the end result is a complex image.  The M-set is a simple iteration of
the equation z' = z^2 + c:

    z0 = 0
    z1 = z0^2 + c = 0^2 + c = c
    z2 = z1^2 + c = c^2 + c
    z3 = z2^2 + c = (c^2 + c)^2 + c
    ...

For an IFS fractal, the equation takes a point in the plane and
performs what's called an "affine transformation" on the point.  Affine
transformations can be translations, rotations, scaling operations or
combinations of all of the above.  An IFS fractal has the additional
constraint that the transformation should be contractive -- that is,
if you took the four corners points of a square and applied the
transformation to the corner points, the resulting polygon would be
"contracted" by the transformation.

Each IFS contains several such affine transformations that are applied
to the points.  A probability is associated with each transformation
to guide the computer in randomly choosing a transformation at each
iteration.

You can write affine transformations as matrix multiplications:

    (x1, y1) = M * (x0, y0) + T

    M => a matrix that accounts for scaling and rotation
    T => a vector that accounts for translation

if we expand out the matrix and vector (any basic linear algebra book
will show you the rules for matrix and vector arithmetic; they are
basically just ways of organizing complex formulas for easier
manipulation), we have:

        | x1 | = | a  b | * | x0 | + | e |
    | y1 |   | c  d |   | y0 |   | f |

which gives the two formulas:

    x1 = a*x0 + b*y0 + e
    y1 = c*x0 + d*y0 + f

The seven numbers in the IFS description are these coefficitions (a-f)
along with the associated probability p.  You might want to look at
the fractint documentation on the spanky web site for comparison with
my explanation: <URL: http://spanky.triumf.ca/www/fractint/ifs_type.html>

I hope this helped out...            -- Rich

Subject: (fractint) Smoothing color bands, revisited (not anti-aliasing)
Date: 24 Sep 1997 14:52:18 -0700 (MST)

Recently, Damien Jones posted his formulas based on Linas Vepstas' smooth
coloring algorithm.  I looked at Damien's work, particularly the
"dmj-mand-smooth" formula, and came up with a few tweaks.  I've included
my alternative to Damien's formula as "smooth_man".

Feel free to dig through the math of the two formulas if you'd like, but
it may be easier to see the differences in the images.  Fire up "dmj1" in
the below par file.  It's a slightly zoomed out Mandelbrot, with the outer
rings shown in blues.  Then, hit "x" and turn the outside coloring from
"iter" to "real".  This engages the smooth-coloring mode, although it's
set to 1 (integer bands) for this image.  True enough, the band spacing is
about what it was before, but there is a slight color shift (blues to reds
in this palette, or about 7-8 color indices).  This is because of a
combination of Damien's iteration counter initialization and the factor of
2 used to multiply the log(log(bailout)).  Since those are both constants,
they don't affect the band spacing.  It's a trivial point generally, but
something to consider if you're precise about your colors.

Then, fire up "smooth1".  It uses my smoothing formula, which is slightly
different in math, and very different in implementation.  The image
generated should be about the same as the first one in "dmj1".  Then, turn
decomp on to 256.  This new images should be exactly the same as the
original, with no color shifts.  (The color "speed" is set to 1 for
integer bands.)

A more significant consideration comes up with zooms.  Look at "dmj2", a
moderate zoom into the cusp region near c=0.25.  When you turn on
smoothing (set outside to real; the color speed is set to 10), something
weird happens.  Most of the image goes away!  The number of iterations
needs to be greatly increased to get the detail back.  This is due to the
clipping nature of outside=real|imag.  If real(z)|imag(z) goes outside of
the range [0,255], then the color is clipped to 0.  I sidestepped this by
using the decomposition coloring instead.  Decomp wraps around instead of
clipping, so the value of z is not a problem.  Look at "smooth2".  The
first image is like the first one of "dmj2".  Then, turn on decomp=256.
The fractal is still there, and the color bands are squeezed in, like they
should be.

These are just minor tweaks, and shouldn't be taken as an attack of
Damien's work.  There are tradeoffs, of course; Damien used "outside=real"
which is much faster than "decomp=256" and also affords the use of xaxis
symmetry.  Also, Damien took the time to better comment his formula and to
add default values for the parameters (neat trick!).  Now, if I could just
figure out the rest of his formulas.  :-)

(perfectly good stuff deleted)

I have never run FractInt on my system yet.  I just recently
downloaded Fractint 19.6 and was very disappointed to find out that
none of the Super VESA modes worked with my card.  I too, have tried
SciTech's software for a remedy but that exercise was futile.  I now
use the windows version 18.21 and it works fine.  Perhaps I will
attempt to port the current DOS version to windows.

As a side note:
I recently downloaded the DirectX 5.0 package from Mickysoft and it
works fine.  It does act sorta strangely when switching from a DOS
mode to my 1600x1200 res.  But that is liveable.

It is an outrage that Number Nine will not support their perfectly
good (slighty old) products.  That really torks me off.  I mean, my
card is only 1 yr 8 months old (purchase date) and it is rendered
obsolete.  Is the obsolescence date for computer hardware getting
faster or is it just me?

This is the card that I have.

Yep... when people ask me what's important to look for in a computer,
I always tell them to buy as much memory as you can afford.  This
helps keep older processors useful longer because new software always
increases in memory appetite.

After a bit of digging around, I have managed to find copies of
Fractint V2.1 and V5.1 (or Fract386 as it was known back then).

Let me know if you want copies of these and I will arrange to send
them to you (e-mail is easiest for me but I might be able to set up
a temporary ftp address if necessary - file sizes are 40.4K and
61.2K respectively).

    I think a complete archive of the fractint development is
a great idea. I have a partial collection, ( I took it off line, because
I needed the diskspace), but if someone has a site where they can hold
all the releases, I will definitely link it into the Fractint Web Pages.

I might know a way too-busy programmer with a fractal-related server
that might be able to find some space (!time) to hold all the releases.

Submit them to ftp://fractal.mta.ca/incoming
 which is a 'blind' directory (no get or ls)
Include the version number in the file name!!!

I'm looking at implementing Linas Vepstas coloring algorithm in
Fractint, and will certainly look at Damien's file and other
offerings here. I'm also interested in the idea of adding an
additional section in the formula file for user-defined coloring
algorithms.

Tim,

One thing that occurred to me is that maybe there could be one additional
coloring scheme added to both inside and outside.  A fractal can be
colored by any function of z, by using a judicious combination of if/then,
decomp, and zmag options.  How about having a special variable (q?) that
can be used for the coloring.  It might work like this:  color index = q,
(which would clamp to 0 or 255 for out of range values) or color index =
256 * ( q mod 1) (which would wrap around).  Inside or outside or both
could be independently set to q, which could decouple the coloring from
the iteration number (no banding), and could allow some typically outside
methods (decomp) to be used inside, and vice versa.  Also, it should
compute quicker than a programmer's formula forced into the zmag or
decomp forms.  Also, Stone Soup wouldn't have to worry about coding
additional schemes (yet :-) they could just give users another tool for
their own development.

Tim,
Would it be possible to have (1) a formula parameter which would be the one
that is used for the color table lookup after escape, and (2) a formula
parameter which can turn on or off interpolation within the color table,
which might be a good way to provide true color and high color support, and
still be relatively backwards compatible. This is the approach I use with
Truemand so that I can use fractint color tables, and in some cases, fractint
formulae.

    Hi,

    I just ftp'd my archive (incomplete) of Fractint versions to
Michael Taylor's incoming directory at Mt. Allison at:

    ftp://fractal.mta.ca/incoming


    He should now have:

    frain13R.zip,
    frain171.zip,

    frain182.zip,
    frain191.zip,

    frasr196.zip,
    frasrc13.zip,
    frasrc18.zip,
    frasrc19.zip,

    I'm sure he will make it available to public access very
soon.

    Others have asked for these and I just chose Michael's site
because he already has an ftp site set up and it was fast and convenient
for me to transfer.  This is far from complete and I know that Jon Noring
and others may have more complete sets but I think there are a few
here that were missing from Jon's list. Especially the source codes,
which I think are equally important.

Ron,

I've already started collecting the old version online.

The ones available so far are at
  ftp://fractal.mta.ca/pub/fractals/fractint/

So far versions: 2.1 5.1 13 17.1 18 18.1 18.2 19 19.1 19.2 19.3 19.4
19.5 19.6 (most with source) and WinFractInt 17.3 and 18.21 (both w/ src).

Thanks to Noel Giffin and David Singer for their contributions.
 Future contributions can be sent to ftp://fractal.mta.ca/incoming/
 and please send me a note when you do so (I can move the files into the
correct spot).

The URL is:

Date: 27 Sep 1997 00:46:08 -0400

Kerry,

Thanks for posting your refinements to the smooth coloring FRM I posted.  I
have examined what I did, and I think I've found the problem.  Since the
smooth coloring technique is used to interpolate the triangle-inequality
method (and others) further down in the FRM file, I'm examining them all to
see how the corrections I made will affect them.  I'm also not sure what to
do, since the corrections would probably change any images generated with
the formulae.

I would, however, like to point out a few things.  First, you point out
that sometimes a high iteration count is needed to bring out colors, due to
the way FractInt clips values from the real/imag coloring methods.  You are
absolutely right!  I have noticed this before, but didn't consider it
terribly important.  You simply showed that it was at least important to
you, and if you, why not others? :)  Fortunately this can be fixed by a
slight reworking of the formula, to make it wrap colors by itself.

This leaves us with the question of whether to return color values for use
with outside=real or decomp=256.  The two will not produce identical
results.  As you say, using outside=real is slightly faster (even reworked
as I indicate above), but this difference is almost inconsequential when
you consider the time invested in the coloring algorithm itself.  More
important, though, is whether colors wrap after 255 colors or 256.  Using
decomp=256 will use *all 256* colors for the outside of the fractal; using
outside=real uses only colors 1 through 255, leaving color 0 for the
inside.  Personally, I prefer the latter.

I believe commenting formulae will become increasingly important as they
become more like algorithms and less like simple mathematical expressions.
I've tried to comment my formulae so others can see where the fractal
formula ends, and the coloring algorithm begins.  If you have questions
about my techniques, you need only ask.

Hi all,

Just a few words to say that there is and unidentified problem the
server of my university.

For a time I have put my pages at

http://www-hs/louvet/jpl0.html
and the French sci.fractals-faq mirror at
http://www-hs/louvet/sci.fractals-faq/faq.html

This can be only a temporary solution, because this computer is only a
Pentium 120 running mainly as a local server for the department where I
work. None of these pages have been updated after September 2, But they
will be soon and I hope that the URLs at the end of this mail will work at
that time.

  You're not going crazy, Paul.  My fractint.cfg file had the same errors
in it before I went in and hand-edited it.  And I too got my copy from
Spanky.
  However (!), this past weekend I trashed my hard drive, and had to go
back to Spanky to re-download 19.6.  The fractint.cfg file is now as it
should be.
  This is the final proof I've been looking for, and I am now ready to
announce my theory that Noel is actually a space alien trying to undermine
the confidence of Fractint users worldwide, hoping to make us overlook the
obvious fact that fractals have an application in both faster than light
travel and crop circles.

I'm not ready to say Paul is crazy yet <grin!>, but I haven't seen
this problem.

I do recall, though, that the feature that allows you to edit your
your fractint.cfg from within Fractint was broken in recent earlier
versions. I didn't notice this because I never use it (in fact I
can't even remember now how to invoke fractint.cfg editing!) If you
tried to edit your fractint.cfg from within Fractint it trashed the
file along the lines that Paul mentioned. However even then it would
be OK when you first installed Fractint, and would stay OK if you
avoided editing.

If anyone can duplicate Paul's problem please let me know.

Tim

Clearly a bad archive got distributed and replaced in short order at
Spanky. Probably, the bad archive was created after some cfg-editing on
the part of the distributor using the buggy version of the editor. (Can
the cfg bug cause the btrace hang though?) I shall replace the bogus
version on the other machine with a new copy from Spanky.

Using the following formula with parameter (0, -1) I get a fractal with
threefold symmetry that contains miniatures of itself and of the M-set.
It appears to be simply connected but not locally connected.  The
boundary appears to have some neighborhoods with fractal dimension one,
and some with dimension two.  What do people know about this?

I set it up this way, as a par file. When I zoom in or out, the image
disappears. Why?
Am I missing something? It would be most helpful if formula were
accompanied
by a par file with required frills like float settings indicated.  It is
easy for you to
make one, just press B.  Then we can see the same thing you see.

    Hmm. I was about to say that this didn't happen and that
the copy at spanky has been consistent, but I have a vague memory
of getting the fractint 19.6 version twice. I'm sure that the copy
I currently have has been untouched since the official announcement
of the 19.6 release, but I did have a copy of 19.6 available in the
directories for a day or two prior to this, (8-MAY-1997). It might have
been possible for eager fractint users to stumble on this near release
version and it might be (Tim can you comment on this?) responsible for the
problems reported.

This is a known bug in the formula-in-par feature in 19.6. We have
already fixed it in our developer version. The workaround for now is
to cut the formula out of the par file and put it in a formula
file. This is a good idea anyway.

Running test97c in the default mode results in some strange patterns in the
low count area. FP gets rid of all of them so they must be integer
artifacts.( But actually aren't all fractals some kind of an artifact?) I
find the figure particularly intriguing for several reasons. It is very
similar to the results from the Prop formula with two notable differences.
The pattern fits in a circle that is extremely close to a diameter of three
where Prop fits in a diameter four circle, and the low count borders are
radically different.(I assume everyone has the Orgform compilation)

Prop is the map for connected Julia sets, see JuliaP, but I can't see just
how to write the Julia form for test97c.

Looking at details in the higher count areas gives results that are
remarkably similar on casual inspection as these two parameter files show.

TendrilP           { ; Both mini figure and apparent Mini Mandelbrot
                     ; P90 640X480 time  0:00:47.29
  reset=1960 type=formula formulafile=_p.frm formulaname=Prop
  center-mag=1.13084/0.161267/25.06297/0.9998
  }

Tendril_97         { ; Both mini figure and apparent Mini Mandelbrot
                     ; From Deweys formula
                     ; P90 640X480 time  0:00:16.15
  reset=1960 type=formula formulafile=dewey.frm formulaname=test97c
  center-mag=-1.13212/0.166896/24.57068/0.9998 params=0/-1
  }

Sometimes trying to find analytic reasons for for why things are the way
they are makes sense, and other times I feel that there is no reason at all
and the results should just be accepted. I sent a copy of Prop to Cliff
Pickover some time ago and his question was why the three way symmetry, and
he's the mathematician.

Well I've done it again. Like the parachutist whose parachute failed to
open, I have jumped to a wrong conclusion. From a radius of the squareroot
of three I jumped to a diameter of three. Blame it on too much Mandelbrot
set where a radius ot two gives four for both diameter and an escape value
when it is squared.

Until Dewey mentioned it I never gave much thought to the apparently smooth
border area. As the itteration count goes up thin lines gradually creep
into the smooth area without any suggestion of interesting detail. If I can
accept that the Mandelbrot set is connected by threads with an
infinitesimal width it seems equally acceptable that the smooth border will
eventually completely break up.

Any math wizards care to comment?

Hello all,

my question doesn't relate to Fractint but it's also about fractals
and graphic programming. I'm working on a Unix machine and on this
machine is a screen saver called "xlock" which creates nice animations
with fractals and other stuff.
My question : Do someone know the algorithms for some of these
animations because I want to program these animations on my private
PC. I looked into the source code, but in the code is to much XWindows
stuff I don't know ( And I'm also to lazy to analyze the whole code :-)
So if someone could send me some information I will be very surprised.

Thanks, ciao Markus Koesler

Still can't get 9.6 up and running on my machine. I installed a new
graphics card but it still won't go.
Is does run an older machine but this baby here says no and:

I'm using the dos version 19.6.
Now under DOS it just won't startup and crashes my system (a Cyrix
486-dx2 66Mhz)
Under Win95 I get the message that it's using a wrong instruction and
halts on
391D:0BE0 interupts used none

So I think (but who am I) that there is a problem in the code.

So I now give you Fractint programmers the option:

Turn the code upside down
or
Deliver a new window version

or else

I will go play somewhere else.

Ha must be a hard choice for you guys and girls &8-D

Hi, Cindy.  I'm Linda.

Some of what you are seeing may be the way your software (or their
software) decodes (or encodes) the files.  Sometimes the par and frm files
I see throw a "3D" in front of every "=" sign.  Look at what you are
getting and if that appears possible, just delete the "3D", re-save the
.par and .frm files, and try them out.  That may solve the problem.

Good Luck!
Linda

Subject: (fractint) Xfractint
Date: 30 Sep 1997 13:34:20 +0100

I am having terrible trouble compiling this thing - I use the PC
verion a lot, and I would like to complile fractint to run on the uni's
Ultrasparcs. They are running solaris.
I edit the makefile as specified in the makefile.
Make
then it makes hc.o and unix.o, then tells me something rude about
stricmp and strnicmp not existing or something.
I edit unix.h, add #define stricmp strcmp and #define strnicmp strncmp
then that works.
Then the help files won't compile.
So I edit Makefile, and tell it not to bother with help.
Fine. It makes all the o files quite happily, but then says...
undefined symbol first referenced in file

socket    /ee/a0/apps/X11R6/lib/libX11.so
and a pile of others. including get peername, xdrmem_create......

Please can someone help me, I miss my fractals :(

Since within a vanishingly small distance of any point on the MSet there
is a smaller but not zero sized midget, how can we say the threads have
an infinitesimal width? Do you mean nonsero width?

As for your question,   I don't see the smooth boarder you are seeing.
Could you post par files of the twop extreams?

I had many hands with btrace with an older Amiga Version of
fractint. With my new gfx card and a newer version the problem is
gone. This could be the same bug happening with odd configs. Would it
be usefull if I test this with the old gfx and/or the old version? The
Amiga Version is different and the bug could be completley different.

May the Source be with you.

Not very informative. What comandline is used to link the .o files?
Do you have all the -L and -l things correct?

Please give a cut&waste of the commandline the make uses and the
errors (run it in emacs with alt-x shell and attach the buffer to
your mail).

May the Source be with you.

What you're talking about is the way email messages are encoded.  They
are sometimes encoded in whats called "quoted-printable".  This means
that special characters are replaced with =XX, where XX is the
hexadecimal ASCII code for the character (so that the mail message
will pass cleanly through 7-bit ASCII systems which might strip off
the 8th bit, which is often used in European character encodings for
accents).  Similarly, all ='s are replaced with =3D, since 3D is the
hexadecimal ASCII code for =.  ASCII chart appended to this message
for reference.

    Oh-oh, my cover is blown. Now my plan to fractally replicate
humans, creating zombie clones and putting them in positions of power
to gain world domination for my evil empire is smashed. Run Bill!
I'll meet you on the far side of Arturis.

    On the other hand, is it possible that when you unzipped the
new version of fractint,  you might have used the option not to overwrite
existing versions of certain files, or as my previous note suggested, were
you one of the eager ones that picked up fractint from spanky in the
first day or two before the official release announcement?

    Is this still isolated to one or two cases? How many others
have had problems with the fractint.cfg file with the 19.6 release?

    Cheers,
    Or should I say "Farewell Earth Creatures"!

    Some futher thoughts on this subject. If your copy of the frain196.zip
file is not 671707 bytes long, then you probably have a copy of the prerelease
version that I held for a few days, and you might experience some problems with it.

How about posting the correct one (.cfg file) here? Or is there a byte
count
or other mark on the correct version of the .cfg and distribution .exe that
we
could check?

    We seem to be anticipating each other here somewhat. As well as the
frain196.zip size of 671707 , the fractint.cfg file has a size of 14601 bytes
I don't have a handy utility to post checksums or CRC values for these files
though.  I could post the fractint.cfg file here, but it is 14 kbytes and I
didn't want to start getting hate mail from all the list members who aren't
concerned with this issue.

    Cheers,

BINGO!   The early bird catches the bug!

First another apology. I was so suprised by the figure that I didn't check
to carefully before posting. Test97c and Prop differ radically at low
counts. Count 2 on Test97c and count 4 on Prop appear virtually the same. I
never stopped to think that a height of 1.732 was a radius of 2 at 30
degrees. As far as I can tell the figures have the same dimensions and mini
high count areas appear at same relative locations.

Here are two parameter files to show what I think Dewey was refering to.

Fig1               { ; view of one side
                     ; P90 640X480 time  0:00:06.31
  reset=1960 type=formula formulafile=dewey.frm formulaname=test97c
  center-mag=-0.158581/0.22547/2.906977 params=0/-1 float=y
  maxiter=255
  }

Fig2               { ; raise count and zoom
                     ; looks like smooth lines
                     ; P90 640X480 time  0:04:11.28
  reset=1960 type=formula formulafile=dewey.frm formulaname=test97c
  center-mag=-0.11277419260928540/+0.22362538875991570/7267442
  params=0/-1 float=y maxiter=1023
  }

Looking at the center of a side at a considerable magnification and a count
of 1023 it appears that we have a smooth border. But if we go down closer
to the chaotic appearing area and raise the count we see high count
filaments creeping twords the center. I suspect that at high enough counts
and magnification the apparently smooth side will break up everywhere.

One interesting feature is that with orbits and lines turned on the two
figures show radically different displays.
