Dave,

 - What do you do about the points on the outside of the field that only
 - have three legal neighbors?

You can either average only three ways, wrap, or "reflect" and use a legal
neighbor more than once.

 - How much random displacement would you use?

Each full step should have half the displacement range of the previous full
step.  This means each half-step should have 1/sqrt(2) the range of the
previous half-step.

 - What language was Fractint written in?

C and x86 assembly.

This is what I'm starting to see for the center point.  Please correct me.

    p(x,y) = [ p(x1,y1) + p(x1,y2) + p(x2,y1) + p(x2,y2) ] / 4
    p(x,y) = p(x,y) + rand(weight to -weight)

Then, for recursion, weight is multiplied by 1/sqrt(2).

Dave,

No correction necessary, this is precisely right. This is the first half-step.

 - Then, for recursion, weight is multiplied by 1/sqrt(2).

Right.

What you do when you hit 0 or 255 is up to you. Personally, I would
generate the entire thing at 16- or 32-bit precision, then check for the
lower and upper bounds and scale/offset accordingly. You could also just
clip intermediate values, or wrap. Wrapping is, of course, bad. :)

This approach starts with a square, then moves onto a diamond, then back to
a square (a smaller one than the first).  From the first square to the
diamond, weight is multiplied by 1/sqrt(2).  Does multiplying weight by
1/sqrt(2) a second time equate to weight/2?  I'm just double-checking my
math here.

You import the PAR. There are a very few things which are not importable,
but most things come in fine.

Ultra Fractal is not a complete replacement for FractInt. It doesn't do IFS
fractals, it doesn't do any strange attractors... just escape-time
fractals, like Mandelbrot, Phoenix, and anything from the formula parser.

Subject: (fractint) Please help with simple(?) math problem

Hi everyone...

For my first post to this list I'd like to ask for help with a little
probelm I'm having.

It's sort of Fractint related--I'm writing a program for creating and
editing colour maps. One feature will be to generate palettes with
waveforms, but I'm really bad at maths.

To create a sine wave I use:

amp*sin(freq*time+phase),

and I stumbled upon a square wave as:

amp*sign(sin(freq*time+phase)).

Can anyone suggest equivalent fomulas for generating sawtooth and triangle
waves?

If I get this program finished I can get around to actually playing with
fractals.

Thank you.

Mark Townsend

Subject: Re: (fractint) Please help with simple(?) math problem

You can generate a sawtooth wave using the mod() function:

y=amp*mod(freq*x)

will give a y wave that linearly ramps from 0 to amp, then drops
immediately back to 0.  Changing freq controls the width of the ramp.

Thanks for the suggestion, Kerry. That's basically what I've been using for
ramps, but I wanted to create waves at the same frequency and phase as the
sine wave. I seem to have the sawtooth worked out now--with the
serendipitous use of Pi and the fact that the byte data type automatically
clocks to zero when you increment it too high.

Dear All,

I've just finished writing a Perl script that reads par files and
generates batch files, just as partobat does.  However, unlike partobat I
can run it on my Linux system with xfractint (the Unix port of fractint).
It should also work on dos based systems (that support perl) but I've not
tested on such systems.  If anybody would like a copy, please drop me a
line (off the list) and I'll send a copy on.  The program is freeware and
my be freely used and passed on.

From Kerry Mitchell's formula, you could put
if(amp>.5) amp=3D1-amp
to make a triangular wave.

Note that Kerry Mitchell's sawtooth ranges from 0 to 1. This triangular
wave ranges from 0 to .5.

Thanks. I'm still working on it. Kerry's reply got me thinking--I should
modify the sine wave formula to fit the ramp and triangle, rather than the
other way around. After a bit more research I discovered how to make a sine
wave with a frequency of 1 fit the range of the map exactly, and that makes
it easier to scale the frequencies of the other waves. The hardest part
seems to be getting the waveform's phases to match.

bothered to tell me how I can get around this problem. Could someone who

All I get is lots of shades of blue and green. The video mode entries

say things like "15k", which means nothing to me.

On a slightly different note, would it be possible to create a disk

The current version of Fractint has a very minimal amount of true-color support;
you can use one of the true color video modes, but palettes in Fractint are
still limited to 256 colors, so when you view a fractal in one of these modes,
you see 256 slightly different shades of blue and green.  The "15k" is a
notation that makes use of the metric system, and means "fifteen thousand"
colors.

>video mode using more than 256 colours just be editing FRACTINT.CFG?
>Sorry, I'm just greedy like that!

I believe so, but the results in Fractint would be similar... you must save the
images and re-color them in another software, or better yet, save the .par for
your fractal and load it into Ultra Fractal, which has good true-color support.
The URL where you can find Ultra Fractal escapes me at the time... sorry!

Subject: (fractint) First 4 pars

Hi all.

These are my first attempts on fractals. They're rather naive, but I'm st=
ill
trying to understand how come if you see that colored default palette it
won't be that colored at all by using another
one (I mean having different colors, not a quasi-continuum color). And I
still don't know how to get that 3d smooth quality that some of the fract=
als
I saw do have.

The Yellow Snow resembles to me Nanook, the Frozen Eskimo, eating some
doggie snow. But I know it seems like one of the snakes you can find at t=
he
beginning of Out of this world, if you know what I'm talking about. FZ,
please forgive me.

The Blue Pulsar, began as a vain attempt on having some flowers out of th=
e
A0 formula. In some part of the original drawing you can see a kind of
garden. But for some reason it didn't get the right colors. Instead it
seemed like a skeleton and I disliked it. But looking at the garden I cou=
ld
see a starlike form. Then I zoomed the star and again had the same proble=
m
by trying to color it. I wanted a Black Star, not a Blue Pulsar, but the
latter won.

The Fire Spear is like a ray emerging from a volcano. I liked the colors =
in
it, though it has nothing special.

Train to Mars is based on a magnetic fractal. I liked the colors too, and
the image of Mars shining above the railways.

Talking about names, of course the first one is named after Frank Zappa's
Don't Eat The Yellow Snow song. And the Pulsar is the first name I grabbe=
d
knowing that I won't (by now) get a Black Star, the Radiohead's song. I d=
o
think that fractals and music have a strong relationship. Haven't you tri=
ed
Bach yet?

Hope you like them.

Nice week,

Alejandro

Subject: (fractint) Taffy Pull

That's not a very original name, but I was in a hurry when I named it. I
like the glossy effect in some areas of the image and the feeling of depth
in other areas. The bridge-like structures seem quite solid, yet
paradoxically, delicate.

Enjoy.

The following A0 pars are zooms, displacements and recolorings

Buen comienzo, Alejandro !  The A1 pars are the first tests
with this formula (an attemp to introduce some parameters
in A0 )

Subject: (fractint) Changing Colors in Fractint

There are two ways:

1:  for color maps already in existence  ( many are available at many of the
fractint support links), you simply hit "C" for color and "L" for list, and
select one of the available color maps.  If the first one is not satisfactory,
then hit "L" again, and the list comes back.  When  you find one you like, you
will notice the border is lighter color- hit escape and you will be back in
fractint with full menu availability

2:  The other way is to design them yourself.
hit "E" and you will see a ghosted box.  Move it to where you can view your
fractal and hit enter.  This brings up your color pallett.  Move the cursor
into the area and select the colors you wish to edit.  Reading the help files
on pallette manipulation will help you here tremendously.
