This sounds normal - if you're referring to the default "1100" rule. Try
another rule to see if more interesting patterns result - "1101101" should
give you a screenful of diagonal stripes.

I'll have a look at ant under Linux. Thanks for the report. Jonathan

George is right. I am dealing with this. Let's have no more
discussion of this on the list, beyond this message.

I will now state the obvious. For the sake of the protecting the
purpose of the list (discussion of fractals):

1. don't post messages to the list asking or commenting about
whether the list is up or down or other list administration issues. If
you must, email me personally. I will tell you in advance, though,
that I have no interest in 36 hour interruptions of the list that cure
themselves. If there is a fundamental problem with the list I want to
know.

As list administrator, I have to post messages about administration
 issues like this one from time to time. I ask everyone else to resist
 the temptation to comment or respond to any off topic messages.

2. Dn't use language on the list that is likely to offend enough
people to start a thread about your language. This is not a list for
the purpose of discussing your language. By the same token, if
someone on the list offends you, email me personally, don't post to
 the list. Your complaint, however legitimate, is off topic. Email me
and I will take care of the problem.

If you are frustrated, send me emails full of profanity. I can handle it
 :-)

3. We don't need messages about newbies or non-newbies or
anyone else that might make anyone feel unwelcome.

Finally, thanks to everyone for keeping the tone of the list so
pleasant and friendly for the vast majority of messages.

Tim
List administrator

You have hit the nail on the head. The type 2 ant works fine, it is
just that the default isn't good for type 2. Your suggestion works for
me.

As Jim Watson pointed out, the Linux and DOS Ant behave the
same, so it is not a Linux bug.

Subject: (fractint) A repeatable Plasma?

Please forgive me if I am asking either the obvious or the
impossible!

Is there any way to 'seed' a value in Fractint 19.6 so that
I can always plot a PREDICTABLE 'plasma' type display? I am
setting up a rolling demo for a group of 11 and 12 year
olds to use in their science fair project, and it involves
a plasma plot being used to make a 3D mountain range; but
some plasma's work better than others and I would like to
stack the deck a bit so they get a good one every time.....

I tried pre-plotting a few and then loading them, but this
does not show the viewer the whole process from start to
finish - unless I cheat and don't use the plot itself, just
load one of my pre-cooked screens instead :-)

Any comments and advice would be appreciated - especially
by the 1,000 visitors expected to see the results.

Subject: (fractint) UltraFractal Halley Formula

Okay, as you've already guessed it's about UltraFractal, not
fractint. My problem is this:

I've put together an impressive array of Newton approx formulas, but
I can't seem to convert them to Halley approx. The resulting formulas
just don't work. I don't get it. For example, below is the "Halley
Cubic" formula, which doesn't work. However, if you change the last
line of the loop section to read "Z = Z - @Relax * (F / G)", this
transforming it into the Newton approx, it works just fine. What
gives?

###################################################

HalleyCubic {
init:
  Z = #Pixel
  Ca = @Co3
  Cb = @Co2
  Cc = @Co1
  Da = Ca*3
  Db = Cb*2
  Ea = Da*2
  Bailout = @Bailout * @Bailout
loop:
  F = Ca*Z*Z*Z + Cb*Z*Z + Cc*Z - @Root
  G = Da*Z*Z + Db*Z + Cc
  H = Ea*Z + Db
  Z = Z - @Relax * F / (G - (H * F / 2 * G))
bailout:
  |F| > Bailout
default:
  title = "Halley Cubic"
  param Bailout
    default = 0.001
  endparam
  param Root
    default = (1.0, 0.0)
  endparam
  param Relax
    caption = "Relaxation Coef"
    default = (1.0, 0.0)
  endparam
  param Co3
    caption = "Cubic Coef"
    default = (1.0, 0.0)
  endparam
  param Co2
    caption = "Quadratic Coef"
    default = (0.0, 0.0)
  endparam
  param Co1
    caption = "Linear Coef"
    default = (0.0, 0.0)
  endparam
}

Subject: (fractint) high res. pictures greater than 2560*2560 or posters greater 32x32 tiles

Why can't I have an image greater than 2560x2560 pixels in size? Where
does that limitation come from? If it where 65535x65535 I could
understand where it comes from, but 2560?

Also, why is the number of tiles for a poster limited? (Well apart
from the stupid 8+3 limit does has.) For non-fat filesystems it is no
problem to have longer names and thus have tiles with multicharacter
index.

May the Source be with you.

I guess

 fractint rseed=xxx

would do the trick (it seems it was specifically introduced to get
repeatable plasmas).
This is in the F1 docs, in the "Calculation Parameters" screen.

The Morse-Thue sequence could well be looked at as a fractal bit sequence
(in the same way that Pascal's triangle mod 2 can be seen as corresponding
to Sierpinski's Gasket). It is certainly self-similar: for a start, just
taking every _second_ bit in the sequence yields the original sequence.

There are at least three ways of generating it (these come from the
ever-enthralling Clifford Pickover's book "Mazes for the Mind")

The first can be implemented as a L-system. Starting with a 0, we take the
sequence we have up to now (to start with, "0") and replace each 0 with 01
and each 1 with 10.

For the second method we again start with 0. For each step, take the
sequence we have up to now, copy it with all its bits flipped (writing "1"
for "0" and vice versa), and append it to the original.

The third is probably one of the easier methods for generating really long
portions of the sequence, since it doesn't need to remember what has
already been generated.
Write down the binary expansions of the natural numbers 0, 1, 2, 3, ...
Now for each number write down a 0 if there is an even number of "1"s in
the binary expansion, and a 1 if there is an odd number.

It's an eerie sequence to listen to (high note for 0, low note for 1,
perhaps) and strangely difficult to type...
0110100110010110100101100110100110010110011010010110100110010110100101100110

Blame is not warranted. I find these images to be complimentary to what I
posted.

I'm always surprised by what others find in the  formulas I post. I write a
formula and then I wander around it trying to see its possibilities. After
banging away at it for what seems an eternity, I feel like I've exhausted
it.

A fresh view is always startling. That is why I asked for Bill's post.
Good, new perspective. I like the images.

Just to let you see where I've explored in this formula, here are images I
created on this theme last year.

Hey. Where did you get those 50 shiny new megahertz, and do you know where
I can get a few cheap? :-)

I work on two machines and since the image size and speed have impact on
time to complete, I try to keep my comments consistent with that fact.

The 150 MHz PC is a laptop. I had some concerns about buying a laptop for
fractaling, especially because that was going to be its primary purpose.
Since then I have discovered that the search for fractal images is mightily
enhanced when it is performed in a lazy-boy recliner with an adult beverage
in easy reach. (Something I would find hard to do with a desktop model.)

Subject: (fractint) 10 PARS and a FRM

Hi all,

I found the following whilst starting to play with my first formulas.  My first real attempt was so
simple the results surprised me.  Someone with better maths might be able to explain the presence of
the 'julia like' zooms b, e and h into the points that are just visible in the 'bulbs' in the 'a'
mandelbrot image.  I have never seen the two together before.
