of the favorites  privately (by later tomorrow) but
if you ever really want to go back and get them you can go to the

This image is actually pretty much the whole Mset which repeats
along the imaginary axis (although the flexballs obscure this).

Thanx everyone for posting the Gravijul formula. I'm sure more people will
be posting it, so thanx in advance. I went to the Fractint archive....boy
was it overwhelming. Looking through all those messages is monotonous and
very time-consuming. Anyone kept a GOOD tab on JUST the posted formulas and
pars? Thought I'd ask before I look through the messages.

On a related note it'd be nice if the archive webpage had a feature to
search through the archive to locate the first/next digest with a
particular substring. A search on "gravijul" from the beginning would have
found the formula Lavondyss wanted.

Kerry,

FOTD 27-03-98 == freaky shape. (Who's Alfie? What's a smallest midget?)
Maybe we cld use Jim's generalized formula for the nascent (well, maybe)
deep-zoom contest? There cld be a third winner, too: most stuzzadelic
fractal found. And since I believe only four people have expressed interest,
that means we only have to find one more category.

For those not on the fractal-arts list, the formula is

frm:MandelbrotN {; Jim Muth
b=p1, z=p2, c=p3+pixel:
z=z^(b)+c,
|z| <= 16
}

Complete monthly collections of all the par files posted to the Fractint list
are available from my Fractal web site at:

http://ourworld.compuserve.com/homepages/Les_StClair/

You'll need to download the formula file too (it's on the same page as the
pars).

I plan to post the March collection (which is fast approaching 300 images!!) a
couple of days after month end.

I don't know about a formal contest, but I'd love to see some
explorations along these lines. Maybe an informal "can you top this"
would be fine rather than a contest

The point of Sylvie's protest that these images are boring and time
consuming may be that if the objective is to produce art, deep
zooming is not the way to go. But there are other reasons besides
creating art to make fractals. I'm personally curious about what is
to be found at higher magnifications. I don't want to see "boring"
images, but I'm not worried if they aren't beautiful and artistic if
they are intriguing and interesting!

There are some complications. It is easy to come up with images that
are self-similar to much shallower zooms, which defeats the purpose
(see the spanky.triumf.ca for a discussion of this.) Usually if you
are zooming in on a midgit, the image is not self-similar. I don't
have a proof of this, but I'm pretty sure it is true. The image
doesn't have to contain on obvious midgit, but the only reliable
method I know of avoiding being sucked into a "whirlpool of
self-similarity" is to follow a sequence of midgits. Once you have
arrived at the desired magnfication, you can explore near the
midgit without fear of getting an image that could have been
generated at a lower magnification.

If you need incentive, here's one. I incorporated a synchronous
orbit (SOI) algorithm into the developer version of Fractint last
fall, but haven't worked on it since. It uses long doubles, which
limits the magnification to 10^20 or so. It works OK, but at that
magnfication it is just starting to get going. I really should port
SOI to arbitrary precision to get rid of the precision limit. If I
thought there were a number of users doing serious deep zooming
explorations, and SOI would help them, I could decide to finish this
off.

For those who aren't familar with what I am talking about, the SOI
algorithm greatly speeds up deep zooms. Porting SOI should help deep
zoom explorations, but we won't know until we try.

Tim

Oh wow!!..Great idea Paul. That would help out a lot of fractal folks. It sorta
reminds me of the "find" option in Windows Explorer. An example would be
"gravi*.frm" or "gravi*.par" or even "gravi*.*" I dunno how hard substring options
would be to program into a search engine though let alone the search enging itself.
It's be great to have though.

Deep zooming would be very nice indeed. However, for those of us who do not
have the newer computers would have a heck of a time trying to render them.
I"m running 100Mhz and it takes forever for some deep-zoom fractals. Plus,
D/L'ing all those pars would be quite painful as well if you do not have
unlimited access such as myself. However, I can wait till the end of the
month and get everything from Les's page..^_^. Just a thought.

Tim,

With SOI, do I have to have a faster machine to render it faster or
would it just speed up the process altogether? If the latter, then I'd
love to see it. Wish you luck.

I have been playing around with another flexible formula, and have
encountered a problem.  This works fine for the z^2 case, but breaks
down; try p1=3, 4, etc. to see what I mean.

Another question/observation: the imaginary component of "bailout"
has no effect (not that I would expect any for a magnitude comparison) (?)

I like this idea very much.  There needs to be some artistic-ness involved to

should probably be sent as GIFs.  Other thoughts:  use a standard image
resolution and colormap?  For those who don't know, I've got a little hiccup of

deeply quickly, without losing sight of areas with mini-Msets in it.  Deeper can

Ohhh please oh please oh please oh please oh pllllease!  Um, sorry.  I would
*really* like to have SOI in Fractint, though.  I've been mulling over adding
something I call Symmetry Recognition (SR) to my Deeper program (as well as a
number of other improvements), and knowing that Fractint was going to someday
relatively soon have SOI would probably prompt me to work on the SR thing.

On the other hand, I suppose if interest in exploring the depths of the Mset is
low, then there are probably other Fractint improvements that should be
higher-priority.  I have not gotten any feedback on how Deeper is working for
folks (or even if it is, or if anyone's even dl'ed it.)  But myself, I'd be very
psyched for SOI!!!

Standardizing colormaps is incompatible with  "artistic-ness." Otherwise I like the

I agree that a standard color map should not be required, however, if it IS
judged, lack of coloring skill should not be part of the judging; rather,
the chance/skill of finding a really cool spot to draw and submit should be
the criteria.

Mark:

I have run into the same problem with some of my formulas.
The following version runs a bit slower, but works the way
it should.  I have no idea why.

MandelMax2 { ; slightly altered by Jim M.
; probably been done before...
; defaults: p1 = (2,0) p2 = (0,0) p3 = (4,0)
   z = p2, c = pixel, a=p1:
   z = z^(a) + c
    |z| < p3
  }

informal sounds great. i wld be willing to maintain the current deepest
zoom images on my geocities page and provide info, which I and hopefully
others, wld contribute, on why such and such an image is interesting, or
how Fractint does what it does and how it might do it better, sort of like
the Deep Zooming page at Spanky. if you think it's boring, that's cool,
don't do it. i don't see how this cld clog up the list; it takes a while to
generate these things, so i don't think there wld be that many pars posted
on, say, a given month, or whatever. or arguing over rules.

it cld be pretty simple i guess it wld be best to just use a standard M-set
formula, with no user-defined variables. besides looking for interesting
objects, if there was any interest, there cld be a sort of repository of
the current deepest zoom, the way the newest largest prime numbers are
announced every few months. we wld just need a rigourous definition of
deepest zoom, if guess. and one wld have to produce the image, so you
couldn't use Kerry's ruse of writing a par without having zoomed. no voting
or talking about how the contest is going.


you spend a week, or whatever, zooming and you just, as Tim said, post yr
can-you-top-this par. since most may not wish to reproduce a particular
zooming marathon experience in the privacy of their own home, you cld send
the gifs to me and i'll put 'em on the web page and post 'em to abpf, if
that is wanted, so anyone interested can look. i already get the SPAM, so i
don't have to worry about mangling my address. it might even generate a
little public interest and, who knows, spawn some practical application
(pace, G.H. Hardy).

i am much more interested in learning and seeing and exploring rather than
a contest per se. and hopefully the expert wld provide some tips. zooming
is fun.

is anyone else interested? then seeya in the M-set, i guess.

Synchronous orbits, when it works, can be more than an order of
magnitude faster than normal escape-time algorithms. It doesn't
depend on a fast machine. But if your machine is fast, AND you are
using synchronous orbits, then everything is faster still! SOI only
begins to be effective near the limit of zooming of double precision
numbers (2^15 or so).

I am not aware of an implementation of SOI for arbitrary precision.
There are some good ones for 64 or 80 bit doubles. My current
implementation is for 80 bit doubles, which goes three orders of
magnitude deeper than 64 bit.

Be forwarned that searching for deepzoom images is very time
consuming. A fast computer helps. We don't really know yet how useful
SOI will be with arbitrary precision, but it seems promising enough
to try.

Tim

(substituting a=3Dp1)

Thanks Jim, that did the trick.  Odd bug, no?

Word to Sylvie: now that I've finally gotten around to making images
with gravijul-v3 (about 3 dozen), it appears it's in jeopardy.  Looks
like you'll need to re-publish, but please name the repaired formula=20
as an alternate (*a, *1, or something) to spare those who got=20
sucker-punched along with you.

Question to the Fractint gods: could you please document the=20
problem so that we can reconstruct the error to preserve the=20
old formulas after the fix is implemented?


Thanks, Bud


P.S.: Since a) I brought up gravijul-v3, and b) it's been two weeks
since my last image post, here are three, all adorned in sil&gold.map
and its sibling.  The first is named in honor of the Cheshire Cat=20
(stripes, you know), Monty Python, and the various "Cats" in=20
the Fractint universe.  The third is another reference to Babylon 5;=20
I had to guess at the spelling, having never seen the name in print=20
(it's pronounced "boo-gee"; I'd ask if anyone out there speaks Vorlon,
but I *do* have a *slim* grip on reality!)

Ha... at 180Mhz it takes too long.  They probably _can_ be interesting,
though... there's a whole page of them that you can access from the main
Fractint site.

Fractint 19 will run in 640K won't it? I heard it runs on even old 286's
without any extended memory at all...

No, I'm not thinking of running it on some old dinosaur or anything. Reason
I ask is that someone reported in sci.fractals that their Win 95 dos box
only sees 640K (which is normal when you don't set fancy DPMI properties)
and Fractint won't run. (I've run it in an unembellished DOS box without
any trouble, except it might not be able to do disk video.)
