Well, yes, but this example hasn't anything to do with 'fractals', I
suppose.
No offense :)

Sure it does.  Have you looked at the L-systems in fractint?  How about
the ones at <URL:http://www.xs4all.nl/~ljlapre/>?  They're fractal, all
right.

No offense taken.

Subject: (fractint) ICQ Number list - Rev.8 - Again!

A number of members have posted their ICQ numbers / nicknames on this list.
I've put them on this list for clarity reasons. If you're not a member of
ICQ yet, and are interested in becoming one, visit http://www.mirabilis.com,
where you can download the software. After having installed the software,
follow the instructions in the program to be assigned an ICQ number.

Felix aka Xilef has opened the ICQ Fractint Interest Group. This group can
be contacted at http://groups.icq.com/group.asp?no=28214

This list was last updated Thursday July 8th, 21:01 GMT+1 (CET).
Many thanx go to Paul N. Lee for tracking a lot of names.
Added a lot of names since Rev.7.
I'll soon be posting Rev.9 - just got a message by Paul N. Lee he had an
update. Thanx again.

An asterisk (*) behind an ICQ # indicates that person is a member of the
ICQ Fractint Interest Group.

This list may seem to have a bad lay-out if you're e-mail reader is using a
variable-width font (like Microsoft products do). For a good overview, you
might have to cut and paste into a text editor.

Any members on ICQ, who haven't mailed their #s yet, or haven't been listed
here (my fault then), please mail. You can also mail if you're a new member
of the ICQ Fractint Group (see above). This saves me some time finding out
names and numbers. :-)


If you notice an error on the list, don't hesitate to comment. This can be
done to the list, but I prefer corrections to be sent to
[e-mail]
Also, if you have a more than one ICQ number and don't use one of them, or
just want your name removed from the list - just send me a mail. Or if you
need a repost.

Thanx in advance,
Christian Strik

Sounds like a rounding error, and it's a little different from what I
was talking about.  Did you look at fltree.pdf?

If you draw L-system lines as rectangles, and put the centers of the
short sides of the rectangles in the same place when the lines they
represent are coterminal, then when the lines are at a bit of an angle
to one another, the short sides of the rectangles representing them
will have the supplement of that angle between them.  It makes it look
like somebody's been trying to chop down the tree, and is about half
done.

PostScript has ways of handling this, but they don't work for lines
that change width and branch.  LParser seems to have a solution.

I was under the impression that fractals were supposed to represent
naturally occurring systems (if that's the right terminology...) So, I
would think that if a line could be fattened up to draw a tree trunk then
that would be a better fractal. yes?

AAAAnnnyway.
Has there been another fractal contest since the first one?
Is there any interest for another one?

A couple have been suggested, but there was no general uproar of support
for either.  My idea was to showcase coloring methods by having everyone
render the same 3 fractals (a Mandelbrot zoom, one Julia with a "lake" and
one Julia dust).  This would show methods that work better for interior
areas, exterior areas, and any that may work better on Mandelbrots than
Julias (or vice versa).

The original contest was intended to settle the "whether fractals are art"
debate. So, everyone was bound to the "contest fractal formula".
Perhaps it would be good to have a contest where each contestant is
allowed to submit one original fractal.
If we got the same support for posting the images and the contest program
that we had the first time (thanks to everyone again!) it might be a lot
of fun!

comments?

It isn't an app really - it's the fractint source code. If you meant

Two causes:
- - sometimes I send mail to you and CC the list, or vice versa.
- - sometimes one person will send to [e-mail]; the list
adds reply-to: [e-mail].  I usually reply to all
recipients, so two copies go to the list.

When he said "edit the L-System code in Fractint", I assumed he knew
that meant hacking the source.

Subject: (fractint) Symmetry Recognition

Howdy all,

I'm trying to design an algorithm to add to my Deeper program (see
http://boralf.agsci.colostate.edu/+AH4-jason/personal/deeper.html
for the details) which will make the program able to recognize points on the
screen which are likely (or not likely) to be/contain mini-Mandys.  In order to
do this, the algorithm must be able to recognize points on the screen around
which features are arranged symmetrically, or Centers-of-Symmetry (COS).  The
center of an everlasting spiral is a COS, as is a barely-visible (or
not-yet-visible+ACE-) mini-Mandy, the latter being surrounded by features showing a
radial symmetry.

The problem my mind is currently gnawing on is this: how should I / can I record
the COS info for a given screen?  If anyone here has any ideas, I'd be delighted
to hear them, but just getting my thoughts out on paper also helps.  Questions
and other suggestions also welcome.  Cheers+ACE-

Jason

To view the webpage, just replace "+AH4-" with "~" (that's a tilde).

Subject: (fractint) web par

The following par is generated from a very slight modification of one of
Damien's frms, dmj-Mand-Pls-Dst. The modification is the following line:

_done = done + 2     ; Done two more iterations_.  In the original frm
the line reads: _done = done + 1    ; done one more iteration_. I am not
sure how significant the change has effected the frm.


The image, I think, is worth a quick look...  :)

David,

Quick inspection indicates that the change shouldn't alter the output of
the formula.  The "done" variable is just used as a flag variable; only for
- -I versions of the formula (which count iterations to stop before the last
one is done) does the actual value matter, or -Itr versions which actually
use the iteration number in coloring.

Thanks for info. I did not think there would be any difference, or if there
was it would be too insignificant to notice. You clarified that for me
nicely. Hope you liked the image...I've been in something of a tinkering

I was going to ask also when our next contest was going to be.  I had an
absolute ball with the last one.

Since we've had so many fabulous formulas this year, I suggest a two step
approach.

1.  Formula contest (haven't figured out the rules yet)
2.  Image contest based on winning formula with categories this time, i.e.
funniest, most gynecological, best in show, etc.

Julia sets from points inside the Mandelbrot set have a single
continuous "lake", much like the Mandelbrot lake, with a nonzero area.
Julia sets from points outside the Mandelbrot set contain only single
isolated points, known as a Cantor dust.

btw: someone told me Cantor dusts have aleph-one points in them.  It
seems to me that they should be aleph-null, because if you're
constructing a Cantor dust in the traditional way (take an interval,
cut out the middle and take the intervals on the ends, repeat) the only
points that remain in the dust are the points at the boundaries of the
intervals you take, and you first encounter each one of them at some
integer-numbered subdivision step, and you encounter only an integer
number of points at each subdivision step, so each point in the
eventual Cantor dust has some ordinal number at which it becomes a
boundary of an interval.

Am I missing something?
