How about the Cantor middle third's set.  It has topoligical dimension
1 and H-B dimension < 1.  (I think its ln(3)/ln(2) or something like
that.)

Paul, in copying the hring frms and pars, I found lots of spurious a`a`a` s
showing up, which of course the computer couldn't understand. I have just
recopied the pars, and hope they will work this time, but could you please
repost the frms for hring
Thanks

Subject: (fractint) re those a`a`a`a`s

Thanks to all who replied. First time I saved them, I forgot to specify
"files all types" or whatever it is, and saved as txt, then went back and
changed the file ending. It gave me those nasty a`a`a`s
Second time, I saved from the same place, but saved as *.par, enclosed in
inverted commas, and, no nasty a`a`a`a`s
At least, that is my theory. Why it does that, I have no idea.

In a year?!  We'll be lucky if Slot 2 comes out by then.  Even if it
does, it will still cost about $3000 for each processor thanks to Intel
targeting the workstation market.  I can't afford that.

What do I do with my Sound Blaster?! <g>

What does that mean again??  Something with USB or FireWire or
something?

Sounds reasonable ($250).

IDE or SCSI? Or one of each?

Hmmm...  Hopefully it'll hang on a wall and cost less that $1000 :-)
Plus this makes that HD space necessary for those large images!

Don't hold your breath. <g>
Seriously, though, I haven't seen it using either PINE on my school's
network or Netscape.  Perhaps everyone should switch to one of those two
and the problem will go away.

Hey, you didn't mention XFree86 4!  Why not? :-)

Subject: (fractint) One formula, many Pars

Hi folks.
    I was doodling a little bit with the parser, tired of not getting what
I whanted:
I'm working on a kind of transform of mandel-based pictures into an
infinite band which should take into account complex numbers from
r*e^-j/0 to r*e^j/0
I'm getting a few weird results, almost what I expected, but with some
'artifacts'? Anyway, since I'm not happy with them, I won't post them
yet.
    On the other hand, I also have a pretty simple formula, that introduces
a cool swirling deformation into mandel-like formulas (z^n + c) that
turns everything into rings...
    Here is the formula and a few pars.
    Enjoy.

    ; p1 deforming factor (expands black areas? Usually leave it 0)
    ; p2 = Bailout - 4      if u use imag(p3)=1, p2 should be high
    ;    but not too much...
        ; real(p3) scale factor for deformation waves. Keep it high if
    ;   you want to see the big picture like an z^n + c formula
    ; imag(p3) exponent of z^n + c (no need to explain this)

Nix. I'm pretty sure that the Cantor middle third's set - a collection of
isolated points - has a topological dimension of 0.

They have to be isolated, since if you have two distinct points that are
not isolated, then because we're talking about the real line we must also
still have every point in between as well. So we have a continuous line
segment, which means that we still have something to cut the middle third
out of.

MLO

PS: You mean ln(2)/ln(3).

TIA,
>> sorry if this insults anyone's intelligence, etc.

I am completely new at this, but I would have thought that
the Haussdorf or fractal dimension would have to exceed the
topological dimension because I thought that those were a
reflection of a 1-D line being "folded" into a 2-D plane and
therefore having dimension somewhere between one and two,
or a 2-D plane being "folded" into 3-D and being between 2
and 3.  I know this is an over-simplification, but is this wrong?

Subject: (fractint) color cycling commands

    As the newest kid on the block, I hate to ask this, because I'm sure
you've all heard it over and over, but the welcome letter to the list made
no mention of a FAQ, so here goes:
    I have recently upped the ante on my RAM from 32 to 64 meg and now the
color cycling commands are dizzingly fast.  On even the slowest I can make
them (with the down arrow) they are still unwatchable.  I can keep hitting
the spacebar to get a general feeling for the variety of color
combinations, but the pleasure of watching the color maps change simply
isn't there.
    Is there a way to overcome this?

Sorry, I had some problems.  When I first posted it, I did it as an
attachment.  Then I got a note that the group had decided against
posting attachments, since some folks apparently can't decode
them.  So I tried to send it using the "insert text in document" option,
but Eudora sent it as an attachment anyway.  Consequently, I had
to cut & paste, and send it yet *again*.  Apologies to all for the
inconvenience.  :-(

Bitchin'...always wanted to see a z^3 Siegel. How'd you manage that... got
a parametric equation for the edge of the nephroid? Scaled the parameter
between 0 and 1 and chose something like 0.6180339...?

Put this equal to 1 to constrain c and get a parametrization?

No, if he wants to experiment with new formulas, let him. If hell freezes

Aha. No need to parametrize, you can just Newton this to find a root.

Welcome Michael,
To control its speed press the number digits, '1' right above Q is slowest.
Then
you could press C and use the ',' or '.'   same as < or > to single step the
color
in color mode. Use ESC go get out of color mode.

OR BUY A SLOWER COMPUTER LIKE A 386!    :-)

I'm slowly working on a FAQ, it is called iFAQ for inFrequently Asked
Questions.
Since you question is more like a FAQ, I should refer you to the documentation.
Get a DOS program called LIST.COM and use it to browse the fractint.doc (I
named
it fractint.txt so ascii editors like PFE can view it.) Scan for 'cycle' and on

the fourth or so try find all the stuff.  Here are a few lines from page 16
...

 <Esc>
 Leave color-cycling mode.

 <Home>
 Restore original palette.

 <+> or <->
 Begin cycling the palette by shifting each color to the next "contour."
 <+> cycles the colors in one direction, <-> in the other.

 '<' or '>'
 Force a color-cycling pause, disable random colorizing, and single-step
 through a one color-cycle.  For "fine-tuning" your image colors.

 Cursor up/down
 Increase/decrease the cycling speed. High speeds may cause a harmless
 flicker at the top of the screen.

 <F2> through <F10>
 Switches from simple rotation to color selection using randomly
 generated color bands of short (F2) to long (F10) duration.

 <1> through <9>
 Causes the screen to be updated every 'n' color cycles (the default is
 1).  Handy for slower computers.

WTF???
It's a dust! It has topological dimension 0; it inhabits a space of
dimension 1. The Hausdorff dimension is always at least the topological
dimension and at most that of the enclosing space.

Subject: (fractint) About that new list...and other things

Hi fractintiers,
Paul asked about the new list and how to get on.  The announcement was unclear.
So here (at the end of the letter) how I got on.  BUT please Terry, please put some
sig on each message.  The address will be quickly lost and then we can't get in even if
we are getting email from the 'new' list.  This is because you have some setting set
so that when I hit reply to sender, I get to author of the article not the list!

If fact I'm emailing this from Micro$oft (by the way, their spell checker sure hates
me for thi$) which when I say NEW Message, put Paul D, I get all tangled up in
mumbojumbo about he is not in the address book. So I post here! Besides I need
to reply to Jean-Pierre louvet about my recent disaster with =3D.  I insist I have
the settings correct - set to plain text. The problem was copying from Micro$oft
Internet Explorer.  Please email me at
mailto:[e-mail]
if there is any problem with tonight's FotN post.

My post about next years Fractint machine was a good troll.  :-)   My MIS guy
was by my cube and we were remarking how P166 machines are only $765. I asked
what he thought I could get a year from now.  The list is basically what he thought.

There have been some questions about my recent transformation formula in FotN
and what email list to post explanations to. I am moving toward having FotN only
appear on the Fractal-Art list since I'm keeping Jim Muth company. And besides,
I consider fractals accompanied with a story an art form. I may even include
another poem.  So I think the explanations will appear in future FotN issues. In the
near future, expect some very interesting transformations which I have not seen
in the literature (except for my own publications).

How many of you think Dr. J is 100% honest or never makes a mistake? Well he
is not human, but I am and might screw up. Take a close look at FotN Elephant
http://home.san.rr.com/jayrhill/FotN/FotN18.html  and see if you can find an error.
This can be a little quiz. There is even a - well not exactly an error, but a definitely
non-optimum solution in last night's FotN.  I'm sure Dr. J will blame me, since I
must not have followed his instructions :-)  We will see who finds these two
screw ups......

F.O.T.N. (Fractal of the Night) 7 Feb 1998 (FractoBowl Bleachers)


The fresh grass in the new FractoBowl field is a total loss, due to the snow!
This is just not supposed to happen here in La Julia, where Dr. J got that very
dark tan last weekend.  Last night he sent me a set of Fractoscope snow flake
images, all having three way symmetry. In fractal space, snowflakes seem to
have different shapes, depending on conditions.  In the real world, snow flakes
have 6 way symmetry (so I'm told, I live only a mile from La Jolla. Using
FractalMapper, I found out Dr. J lives about the same distance from La Julia).

Dr. J does not get to see snow except in the higher iteration regions of the
most
fractal spaces. So when it snowed where he lives, he could not resist gathering
samples while at the FractoBall field. As you know, he is not in the greatest
of
shape and, no body told him collections of snow might be slippery.  You
guessed it, he slipped and fell on his plus real side. That means he has to
file
paper work, get details, fill out forms, you can't even just guess the half of
it.
Of course he had to get the plans for the FractoBowl stands where he slipped.
 He thought I might be interested in the blue prints. Indeed I am and I'm
passing them along to all of you.  Figure 1 shows the overall layout. Observe,
at least in these blue prints, the green playing field has an exact sharp
boundary
where the stands (in blue) begin. See especially Figure 2.

While I am very glad to get the blueprints, I shall be even more interested in
what Dr. J discovers if he ever gets around to examining the snow samples. I
sure hope they don't melt.
