Subject: (fractint) Bug correction on new Truemand formula parser
Well, the inevitable happened. When I tried to create a fractal animation
using the formula parser, it didn't work. The bug was easy to fix, and the
revised version is now available on my web site. I have also put a new fractal
animation on the animation page. The animation was produced with fhe formula
parser and a variation of one of Sylvie's formulas.

Subject: (fractint) Cpd_Julia for Mike Traynor
I'm posting this to the list because Mike Traynor's isp will not
accept email from Netcom. I figure this is OK since some others
may have missed the formula.

Here it is. I had the name slightly wrong. I'd forgotten I'd written
the formula to do both Msets and Julia sets. I've included a few of
the original pars.

Paul has out done himself here, in fact he has four-up-ed himself! I am
reminded of my eighth-grade teacher who grew up as a boy with 4 sisters
to deal with. I asked him how that could be so bad (I have one sister).
I reasoned the 4 sisters would keep each other busy. Well, he replied
that they "4-up" on you.
By the way, there is an 4 in one image upcoming in the Dr. J series
(Fractal-art list). But it will be zoomable but a different kind of four in
one.
There is one more thing to note about zooming Paul's image. If you
try to pan, the image only draws the new part. You will also need to
do a slight zoom in or out. Here, let me try one here... boy this is
_neato_.

Good weather hiatus.
I'm tossed between the math and the art. Should the math and choas destine
the art or should we bend the math and apply structure to the chaos to give us
a nice image. What are the pros of one versus the pros of the other or maybe
its just a personal preference.

Thanks for the info. Here's another thing I've discovered: if you
use passes=g you will mess up all of the images except the one in
the upper-left quadrant. This is because the zooming code uses
the values of the pixels (0,0), (0,1) and (1,0) to get horizontal
and vertical distances between pixels and with passes=g the pixels
at (0,1) and (1,0) are skipped on the first pass.

What's the difference? :-)
Really, the only that distinguishes mathematics from other art media is
that it requires the learning of its own language (and to some extent, that
language is an art form in its own right).
So mathematical art or artistic mathematics? I say it is a personal
preference - it's the same thing anyway, so go with what turns you on the
most!

comment {
Here is the Mset version of my Four_Julias_Z formula. The
same limitations apply plus these images cannot be rotated
(maybe in a later version). The par I've included is already
a fairly deep zoom, so after displaying it you can press the
"z" key, then the "F6" key, then the "F4" key, and then "Enter"
twice to get the whole Mset (which probably won't look very
good, but it will give you something to zoom into).

Hi All,
For panning, you don't need to zoom in or out: just select the same vid=

From: pjcarlsn@ix.netcom.com (Paul and/or Joyce Carlson)
Subject: (fractint) Correction to Four Mandels Formula
When I posted the Four_Mandels formula late (too late!) last
night I said that the images could not be rotated. That is
true for the formula I posted. However, I had made a
couple of unnecessary changes to Sylvie's code which killed
the rotation capabilities of the formula. To restore the
rotation capabilities, in the block of code that reads:
IF (px == 1 && py == 0)
delta_x = real(scrnmax) * real(pixel - z0)
ENDIF
IF (px == 0 && py == 1)
delta_y = flip(imag(scrnmax) * imag(pixel - z0))
ENDIF
change the line that reads:
delta_x = real(scrnmax) * real(pixel - z0)
to:
delta_x = real(scrnmax) * (pixel - z0)
and the line that reads:
delta_y = flip(imag(scrnmax) * imag(pixel - z0))
to:
delta_y = imag(scrnmax) * (pixel - z0)
which will change the code back to the way Sylvie originally
had it.
So, why did I make those changes? Essentially, I did two
things I shouldn't have done: First, refusing to accept the
fact that I can't program late at night the way I could
twenty years ago, I was working on the formula way too late
at night, and second, I made a change to make the formula
work without understanding why it didn't work, breaking a
cardinal rule of computer programming (and I think formulas
of this complexity have crossed the line from formula writing
into computer programming).
I originally used my 3Way rendering for the image in the
first quadrant instead of the Astroid rendering that is in
the present formula. And I couldn't get any of the images
to display properly. Failing to find any error in the 3Way
rendering code, I thought, "lets see what happens if I keep
delta_x horizontal and delta_y vertical." So I made the
changes and, lo and behold, all the images displayed properly
except for the first quadrant. I then used the Astroid
rendering for the first quadrant and all the images displayed
properly. Then, it being very late, I said, "good enough"
and posted the formula without checking if the changes I had
were really necessary. It's now obvious to me that I had
made some error in the cutting and pasting of the 3Way
rendering code that affected all four images.
Anyhow, my apologies to all, especially to Sylvie - I should
have never messed with her portion of the code - she's much
better at formula writing than I am. I should have sent the
formula to her before I posted it, seeing as how I messed
with her code - next time I will. My only excuse is that
around midnight several brain cells were fast asleep.

Hmm... If it is again because of the pascal crt error, you may use an
executable patch available from http://www.merlyn.demon.co.uk/zipfiles

Subject: (fractint) Correction to
Paul,
Just to be safe, could you please repost that formula in it's entirety =
as
it should be? With all of us making various cuts and pastes, there are
bound to be errors! Somebody has already reported getting a "null pointe=
r
aassignment" when using the formula, although I didn't when I used the
version as originally posted.
