How much of a speed gain would putting critical sections in assembly gain?
I could learn PPCAsm, if nessisary.

Is this the way it is in XWindows? Hmmm....maybe I'd better get down to
reading the megs of sources as soon as I finish fixing the other Mac.

Anyway, it might be possible to write some quick things to get it running
on the Mac soon. However, it may take time to do a complete Macinization of
it.


PS: How much of this will need to be re-written to work under a 32-bit
environment?

PS(2): What are the sizes of int's, long's, float's, and double's over
there? Where is it important that I preserve these?

(On a Mac PPC, short's are two bytes, int's and long's are 4, floats 4,
doubles 8, and long doubles 16. floats/doubles/long doubles differ under
the old 68K)

Actually....

There is no need to assert a copyright at all to have a copyright.....one
just does, if the work is original and is one of the thingys which can be
copyrighted. Note that a math formula can NOT be copyrighted....so assert
away....it doesn't help.  Works of art....books, pictures, etc. are
copyright-able.  Recently, an algorithm sufficiently complex to be called a
program appears to be copyright-able. But there are oodles of grey zones in
the intellectual properties arena.....which is why lawyers who specialize
in this area are so very well paid and have job security.

Anyway....a copyright has been cleverly characterized as "the right to
sue." So, unless one is willing to sue and can show that they have been
harmed, asserting a copyright is a waste of time.

I do think that trying to collect for infringement of a copyrighted fractal
would keep the lawyers arguing for ages since the fractal is, on one
hand....the product of a mathematical formula and an algorithm which is
most likely in the public domain. However, a Good fractal does not appear
to be the product of math alone......hence the great Fractint contest of
1997.

When is the next contest, btw?? That was great fun.

Angela .....I manage contracts for a major corporation and we do a lot of
thinking about intellectual properties...but I am not a lawyer

Well, we should not do this all over again, I just might note that my
wife is a publisher, with about a dozen books now.  There is a specific
way you should note your copyright, it is

(c) name, date.

A copy right is good for 70 years, so you need to date it. And if you
don't state your name, how can anyone ask permission for copying?
You could not defend an no-name posting.

How about that, Fractal of the Night (and Fractal of the Day) were
mentioned by PC World, way cool!  Paul Lee posted a notice that
the Fractal-Art list got a review in their Tip of the Day, itself
another list sponsored by PC World.

One more thing. You may be following Dr. J's crazy adventures over in
Fractal-Art, (the parent of Fractint list). While Dr. J may have all the
time in fractal space to explore, I am finding less time to follow him
lately. Back here in the real world, I am a real rocket scientist. You
may have noticed some of my posts hail from nosc.mil, when I'm
taking a quick brake, of course. Well, that is the Navy lab here in
San Diego where I work as a contractor. During the month of March,
I am testing our product for delivery and will be working graveyard shift,
10 hours a day 7 days a week. So, likely, I'll see you only fractaly in
the duration.

It has been pretty tough getting the posting out the last few nights.
We had a power outage one night (in a storm) and my long hours have
already begun. My computer sits on a board with ends resting on two
other tables. The other night, one edge dropped off, sending the
computer face down on the carpet and the monitor into my lap.
External ZIP drive, key board, speakers, mouse and Internet
connection box flying.  Without crashing Win95,  I closed everything
down and shut it off, then put it all back!  Lucky this time.

Anyway, Jim Muth deserves a big hand for his FotD for about a year
now.  It has been a real challenge keeping pace with him. I have
learned a lot working with Dr. J and it has been fun.

Stay dry, warm and healthy,
Jay

I have been making some of my own fractals using the formula parser, but i

basin of attraction? Like the way the Newtbasin does to the newton method.
does anyone have any suggestions?

Subject: (fractint) Colors

Hi,
Does anyone have a colormap they might be willing to share that wld create
the effect of a bug in amber? I have tried and I am unable to do this
myself, and now I shall go to bed; but it is discouraging to create images
that otherwise would be cool if the colors were right. So I'd really
appreciate it if if maybe someone cld at least give some general tips
toward getting these colors. I am Sylvie Gallet's triangle formulas and
using the Fractint color editor. And once again: the desired effect is: A
BUG PRESERVED IN AMBER.
Thank you.

<post scriptum>

I recently obtained a copy of Fractals for Windows. Now the authors of this
book are very enthusiastic about Winfract (this was circa 1991). However,
it is unclear what version of that program the book addresses, because the
installation program doesn't work Win95.
I considered playing with the current version (18.21, I think) available on
the Fractint page, but for seem reason this seems to be discouraged (it
says something like, OK, if you _really_ want it, here it is, but be
forewarned). Has anyone used this w/ happy results? Also if someone has an
executable version of the Winfract version that shipped w/ the book and
wouldn't mind sending it to me, or can tell me where I might download this,
I would appreciate that, too. My mail server allows huge binary
attachments. As a very last resort I wld re-compile it; however, I have a
relatively small hard drive and don't really have room to put my Borland
4.xx compiler back on. I'd have to delete somthing big, like Windoze.
Goodbye.

Thank GOD!  I thought it was just my setup.  I haven't gotten mail at

Mrvn wonders:

Well, I've done a little experimentation, and come up with a method for finding
the tangent points for all the buds off the main cardioid.  It is an iterative
process in that you need to know the tangent point of some bulbs before you can
calculate the tangent points of other bulbs.  Once again, I *intend* to have a
graphical description up on my web page by the end of the weekend, but I can't
promise this.  Below is the verbal description.

We will be concerned only with calculating tangents for bulbs off the upper
(Quadrants I & II) half of the main cardioid, since the bottom half is a mirror
image of the upper.  Consider that there is a series of largest bulbs off the
main cardioid, starting with the huge period 2 bulb, then including the period 3
bulb, the period 4 bulb, etc., where the next bulb is always the next largest
one to be found travelling in a certain direction along the edge of the
cardioid.   Let us call this first series A.

The procedure for finding the tangent point of any of the bulbs in series A was
described in detail in my last email on this subject... what we are interested
in is knowing the angle, which we'll call theta, to use in the procedure.  For
series A,

     theta = 360/p

where p is the period of the bulb in question.  Therefore, theta = 180 for the
period 2 bulb, 120 for the period 3 bulb, and so on.

But what about the bulbs between these bulbs?  Let's look at the period 5 bulb
to be found approximately halfway between the period 2 and 3 bulbs.  The period
5 bulb (which will be abbreviated as p5 from now on, to be read as 'the bulb
where the period equals 5') can be thought of as the largest bulb in *two*
'smaller' series of bulbs which consist of the larger, smoothly shrinking bulbs
on either side of p5.  The series extending clockwise from p5 consists of
{p5,p8,p11,...,p(3p+2)}, and the series extending counter-clockwise from p5
consists of {p5,p7,p9,...,p(2p+3)}.

Now, we need to be able to recognize these so-called series of bulbs because in
order to find theta for a bulb, we must know the tangent point of a bulb which
'bounds' its series.  For example, the p5 bulb's clockwise series is bounded by
p3, and its counter-clockwise series by p2.  Let's denote a bounding bulb as
b(p), and the angle theta for the bounding bulb as theta(b(p)) (note: no
multiplication is meant to be implied here - it is just a labelling method).
Using this notation, we can define theta for any bulb off the main cardioid as:

theta = theta(b(p)) +/- theta(b(p)) / p

The +/- will be a plus sign if the bounding bulb is clockwise from the bulb in
question, and a minus sign if the bounding bulb is counter-clockwise from the
bulb in question.

Let's work through an example or two.  As we've already determined, the p5
bulb's bounding bulbs are p2 and p3. To find theta for p5, we need to know theta
for at least one of these bounding bulbs; we have already done this above.  To
find theta for p5 using the p2 bulb:

theta = 180 - 180/5 = 144

Or, to find it using p3:

theta = 120 + 120/5 = 144

As one more example, consider p11 between our p5 and p3 bulbs.  What are p11's
boundary bulbs?  They are the bulbs which define the 'series' to which p11
belongs.  To determine this series, start with p11 and move along the edge of
the cardioid until a bulb is found which fits the description of a 'local
maximum' in regards to size (not period number).  Moving counter-clockwise, we
encounter the p8 bulb (which is larger than p11 in size), but if we move almost
the same distance again, we encounter p5 - this is one bounding bulb of the
series to which p11 belongs.  Looking clockwise from p11, the next largest bulb
is p3 - this is the other bounding bulb.  And because we have already figured
out theta for p5 and p3, we can find theta for p11 as either:
theta = 120 + 120/11
or
theta = 144 - 144/11

I will really try to get some graphics going on my web page this afternoon,
really!
Cheers, Jason

I discuss Winfract vs. Fractint in some depth at

http://wizzle.simplenet.com/fractals/hints/tips-fractint.htm

It's a perfectly good program, but it does have some limitations.  On the
other hand...for organizing files....particularly looking at color maps
with an eye to deleting some or renaming files....it is very useful, I find.

Subject: (fractint) 3d Mandexp fractals

Can someone explain to me how I can make a 3D fractal, if I use "c= x + yi"
(the current point) and "w" is the third coordinate, and plug them into the
formula

"z(n+1) = z(n) ^ w + c"

It's kinda like sliding the mandexp set through a third dimension and using
that corrdinate as the real exponent component.  If this is possible, and
you understand what I am saying, email me back...

Thanks,

Subject: (fractint) Re: A Geom Construction of the M-set

To all interested,

Ok, I've got a few pictures to help with my description of how to find the
tangent points for all the bulbs off the main cardioid.  I'm not sure where to
take it from here... I can see how the buds off the period 2 bulb might be
described, but what about period 3?  How does one describe the line which
represents the 'x-axis' for the period 3 bulb?  I'd check out relative areas of
bulbs, but I think this has already been done - anyone have two cents to add?

Anyway, For a mediocre improvement of my last couple emails on this subject,
check out:

I believe that lyapunov.map would be a good place to start.  The colors are
relatively close.  However, you might need to do a bit of cycling or actual
map editing to get it right, depending on what you're trying to amberize(?).

I have.  It's good for if I want to pop into Fractint and do a quick render
of something (like the Mandelbrot Set) at low-res so that I can play with
it in Photoshop.

I wonder if that actually was 18.21...  I haven't seen any updates to
Winfract for awhile.

Hi Tim:

I've noticed a problem with Fractint with regards to the number of
formulas that can be stored in one file. Because of this problem, I
limit myself to having no more than 100 formulas in a file. I discovered
that when I had somewhere around 150 formulas, the formula names listed
on the selection menu would run up against each other like this:
formula1formula2formula3 etc. It didn't matter how few characters there
were, the same thing would happen even if they were frm1frm2frm3frm4frm
etc. This problem does not occur with parameter files ot color map
files. Would you kindly rectify this snafu in FractInt20? I'd be
eternally grateful to you.

Bob Margolis
