Subject: (fractint) Quartz formula pars

Hi,
Three pars generated from two of Paul Derbyshire's Quartz formulas. For some
really good ones download the par file on his web page. If you hate these,
please tell me--I don't know what I'm doing and appreciate tips. Peter

Hi
Just testing (but included a very quickly generated par file:), because I've
been unsuccessful forwarding something -- if this works I'll send it directly,
Jay. Otherwise, I think we shall have to look in Knuth. My apoligizes to the
great artists of the cave at Lascaux and to anyone sick of my posts.

Sorry, Jay. Made a bloody mess of that forwarded message. Here goes again.
Tried to hand edit that junk out of it. If this doesn't work, never trust
anyone who takes a screen name like Clamcake.

OK gurus,

See if you can explain this.  Here is another case where just changing
the  magnification a little changes the image a lot.  The first one is in the
transition  between the next two.  Use 800x600x256 setting since it image is
sensitive to scale.

Hi Wizzle,

I tried to post this to the list. No luck.  Clamcake (Peter) also tried.
Think
you will have any luck or is the list down but good?

Subject: (fractint) some more variations

I've been playing around with palettes and have gotten
some interesting effects when color cycling on the very
nice Christmas ornament from Wizzle and Jill Lawson.
(It's not Christmas anymore!)  The main effect of this is
in the cycling and something disturbing is happening at the
edges.  I think some of the house guests watching this
were on the verge of a seizure like those children  in
Japan watching animations.
   I also took the lovely elegant variation of Jacco's contest
entry by Wizzle and turned it into sort of an art deco neon
sign.  This also needs to be cycled.  (Now I  will try to stop
colorizing other peoples' creations and go do some basic work
on formulas. )  palettes from fracXtra

I loved all your color variations and spend a lot of time playing with
color myself.  When I'm looking at fractals on the web, I so often wish the
artists had taken a little more time experimenting with the "perfect" color
map.

The precise control Fractint provides over color mapping is one of its most
wonderful features.  I hope.....if we go to true color....there is some way
to produce something like a palette....or turn certain areas of the fractal
black like we can do in Fractint.

Compare the two versions of Paul Carlson's contest entry.....one with a two
color map I made after seeing how wonderfully bold that makes certain
fractals....and one with my taupes3.map which uses the more conventional
gradiated bands of color.

I just counted .....I produced 8 variations of Paul's 2-color map!!!! all
in the pastels I like so much. Thanks so much Paul...I've learned oodles
from seeing your images and maps.

important a color map can be.  I think the first image is great (my map was
a variation on the one Paul used in the contest).  The second image is
definetly so so.........sooooooooooooooooooooooooooooooooo

Clifford Pickover's quartic variation of Ushikis's "Phoenix" Julia set
equations: Z = Z*Z - .5Z + C, X = Z*Z - .5Y + C, Y = Z, Z = X

I haven't learned how to write formulas myself yet (may be beyond me entirely).

Subject: (fractint) DEEPER Program

Howdy all, hope your holidays were as bloody as mine!  (I
got Quake II... ;)

    I've been attending the list sporadically lately, but
am now set up at home and will be getting more involved in
the fractal fracas, I promise!

    News:  I've managed to produce some C++ code (a.k.a the
DEEPER prototype) which compiles under GNU's g++ compiler
(with a couple of warnings) that can be used to zoom
randomly into the M-set, and probably other escape-time
fractals.  And unlike my previous attempt, this one doesn't
seem to fragment the hard disk.  Anyway, I'm at the stage
now where I'm trying to decide whether to try to add my
algorithms into Fractint, or instead set it up as an
add-on, similar to the way the FILMER program functions...
if that's possible - I'd need to read up on the abilities
of a DOS batch file... right now, I've got a DOS batch file
running the DEEPER proto and FRACTINT in an infinite loop.
I should have this prototype and information on how to try
to use it set up on my web page before the evening is out.
Comments, suggestions oh so welcome!

Happy New Year, and remember, Think and Thrive, Don't Drink
and Drive
(yeah, I just thought that up!)  Jason

Hiya Jason.....

Congrats on getting set up....were you the one crashing the net yesterday
with your new Christmas toy?? (you and 18zillion others)????

I don't want anything that fragments my hard disk.....it's in two pieces
(partitions) and I would prefer that it stay that way.

My holidays were fine...I downloaded Iterations, Flarium24 and TieraZon from

http://home1.gte.net/itriazon/

The programs make nice fractals but I find the color control baffling.  Can
anyone help me?
