Subject: (fractint) Client-server Fractint

This is very much what I had in mind when I suggested the idea, after all
you don't get any speed increase with just one server at work :-)
If everyone on this list (who I presume have internet access) ran a
Fractint server on their machine, and shared with the other readers, we
could get some seriously fast fractalling done. Especially with the
difference in timezones meaning many machines are idle when others are
being used for fractals.
If anyone has a spare supercomputer, they could run a Fractint server on
that as well...
I would suggest we send "chunks" of say 50x50 pixels via UDP, rather than
the whole image at once. Of course if the fractal being calculated was
very slow and complex, it might be good to have smaller chunks than 50x50.

Subject: (fractint) Simplenet and a Formula
So, Wizzle, how do you get a simplenet account with unlimited webspace,
and what does it cost?
ObFractint: Here're two formulas and PARs. Very interesting, multicolored
Mandelbrot sets by critical points.
Quite beautiful too.

Subject: [none]
Hi,
I was wondering if there is an easy way (easier than by hand) to
find the values of variables in a formula. Perhaps future versions of
fractint could include a debug formula option which would dump values over
succesive iterations to text files.
:) Ben

Subject: Re: (fractint) Client-server Fractint
Each server should do a 'scan' to determine the parts of the image it is
assigned which are slow. The sizes of next generation chunks could be
determined for each portion using a quad division algorithm.

I, too, have off-line storage space available, for a good cause such as storing
fractals!

Angela,
>> Speaking of....is there a way for me to force every view of a par to =

"g" is a guessing algorithm and may lead to generating a vastly
different image than what was specified in the original par, particularly=
in very chaotic areas where very small lakes or islands may be missed, an=
d
continuous lines may appear discontinuous, etc. Passes=3D1 is the only
non-guessing algorithm. Alsi if in the par passes=3Dt or passes=3Db and =
a
fillcolor is specified, the image will also be very different. Instead, f=
or
speed, use a viewwindows mode. Forcing a par to not display what the
author had in mind is a very bad idea - one might just as easily try to
force all pars to load with his favorite color map.

No. In my earlier post I meant that neither the "Name the Artist"
or "But is it Art" pages appear to have stimulated much participation.
(Posts like yours herein are what I had originally hoped to elicit.)
I interpret this as a general lack of interest so have abandoned any
plans for further cooperative experiments. I have no intention of
removing either page in the near future.

For the record, I did not choose these fractals. Each artist
submitted their personal choice. They do offer an interesting
fractal spectrum, don't they?

Personally, I don't think they are at all superficial. Sylvie's piece
offers wonderfully subtle and soft colouration and I believe that
to be the subject of the work.

You are very kind. But these artists have spent a great deal of time
studying and perfecting their work. In contrast, Margaret and I have
been at this for half a year and are new kids on the block. Perhaps
we have between 200-250 fractal hours between us. It would be
presumptuous of us to assume similar expertise.
I assure you this is not a case of false modesty. We think some of
our work is very good but most of it is, well... okay. We are
accustomed to the complete subject, lighting and compositional
control of black and white art photography as afforded by
darkroom and studio. Contrarily, our command of fractal
imagery remains maddeningly elusive.
If we continue we will undoubtably become quite skilled in time
but, unfortunately, that time is not today.

Strange and wonderous things may come to pass within the
shadowy domains of faerie...
Seriously, Margaret used Stephen Ferguson's wonderful Flarium
program for this one. The hint of the fairy figure appeared
quite early and she experimented with colouring and
filtration to bring it out. We both thought it should
be more jewel-like but were unable to achieve the desired
luminosity or translucence solely within Flarium. We resorted
to a secret weapon- PhotoShop. I don't recall all the details
but I think I eliminated some background information, applied a
very small amount of glow effect and tweaked the contrast
and brightness. We no longer have the original Flarium data
file so can't advise the formula, filtration or colouring
method. Sorry.

There is a limit to how far we can predefine things in our arguments.
I imagine the good Doctor was confining his remarks to the macro
world.
Still, I wonder about his premise. Most multicellular life forms
are incredibly repetitive in somatic structure. As fractals excel
at containing repetitive information, I wonder if somewhere along
the road evolution has not hit upon this as a storage mechanism
for genetic information. Apparently, a substantial amount of DNA
information appears to be random noise. At least, we don't seem
to understand its presence. I have no basis for this speculation;
I just wonder at times.
