Subject: (fractint) PAR: Misc. images

Here are two images I've made recently.  The owl is from Paul's 'Devil'
formula.  Second is Tim's Error- I just adore that formula I don't know why.
Also, keep your eyes pealed for my first poetry/fractal combo.  I need to
fix the poem a bit first, but I'll try to post it to the fractal art list
tomorrow.  (I think it's more relavent there, and I hate to crosspost-
aren't most people on both lists?)

Anyway, I hope you all like these!

I believe the dice to be in an infinite-dimensional Hilbert space :-)

Huh? I don't know about the US, but here in western Europe many, many people
use CorelDRAW.

I'm quite sure they were made of magnetic monopoles. Well, the cheap ones of
course. The 'elite' editions were often magnetic hexapoles.

Indeed, I couldn't find any app on my sys that can read .ai files. And I
have a lot of grafx programs :-)

Indeed, WMF is worthless for any complex grafx.

I suggest DXF, which is also widely supported and can do a lot more than
this WMF.

I'm afraid turning Goedel's Theorem inside out is against the second law of
thermodynamics. I therefore favor a 144-dimensional functional analysis to
be performed before the root-taking, as this dodges Goedel's theorem (can
anyone prove this?).

Subject: (fractint) TripleMutant demo formula

comment {
This formula and par give an interesting demonstration
of how the influence of the three functions in Oliver
Klimek's TripleMutant formula "infiltrate" an image as
the iteration count increases.

The par is initialized with an iteration count of 1.
Run it, and when done, the press the 'z' key, increase
the value of real(p1) and run it again.  Here are some
suggested values of real(p1) and what you will see:

1  - all blue, fn3 dominates
5  - red (fn1) appears in lower right corner
10 - red disappears except for shading to magenta
12 - red reappears, along with green (fn2)
15 - a pattern is starting to form
20 - a spiral is taking shape
25 - the spiral is well formed
30 - more detail is added to the spiral

Although I haven't had a chance to really think about
it, I find it interesting the way the advance of the
spiral takes place (iterations 12 thru 25) with a
blob of red (fn1) at it's tip which is then pinched
down by the other two functions in successive iterations
to form the spiral.

You can run these at low interations for speed.
They run quickly because of the low iteration counts.

It seems as though a more complete sequence similar to
this might make an interesting animation.

Like my earlier posting, this is very rough.  Improvements
that could be made include a more accurate coloring method
and modifying the formula to eliminate the cabs() functions.
Even with these inaccuracies this little demo gives a
pretty good idea of the effect of the three functions at
various stages of the iteration.

NOTE: At the last minute I added the second par that uses
differnet functions.  Run the same sequence as for the first
par.

Being new to gobs of frms and pars, I found the best way to get my frm's all
sorted out
for Fractint was to use Orgform.  In my frm directory all I have are the
orgform frm files.
All the originals with comments I keep in another directory.  When a new par
comes
in and I try to run it and it can't find the formula I know I need to request
it and whenever
I get a new frm I make sure to run orgform.

Hope this helps,

Thank you for the info on IRC.  I think I'll be able to use it soon.

Regarding RSP_1011 DUPLICATION, this was the first formula I wrote long before
I had
any system for keeping track of formula perversions.  I hope it won't happen
many more times.
If everyone who saved that disaster of a first post and has that formula could
you please
rename it rsp_1011m as S.Gallet suggested. Thank you for your patience.

I read some time ago that someone maintained the par and frm posting on there
web site but I can't
remeber who.  Could someone drop me a line telling me where it is. Thanks.

 I suspect that .WMF is going to be read by anything that uses the
windows clipboard. Other than that... .ai is the most widely read
format that I know of other than, maybe, PDF.

} Indeed, WMF is worthless for any complex grafx.

 Yes... it is.

If you really want all of the information for Windows Meta Files, then
I'll send you the complete details privately.  For that matter I can
send detailed information on over 100 graphic file formats to anyone

Fractint 19.6 runs fine under OS/2 with our Diamond
Stealth64 Series 2000 display adaptor. It won't run
on the same hardware under W95.

I'll stick with OS/2, thank you. W95 doesn't work for me,
and NT won't either!

I use three different versions of it, have for years!
There's a reason why CorelDraw basically controls the
vector graphics market outside of the graphic designers
speciality shops! ;-)

Except that DXF support for fonts was pathetic, last time
I looked. But then, I haven't wasted my time dealing with
DXF for a few years now. Any program that can produce a
DXF file can just as easily produce a much more useful
and better PS file! ;-)
