Introduction:
Mand2000D is the demo version of Mand2000, a fractal exploration
program created by Cygnus Software. Mand2000 is a tryware program. You
can use the demo version all you want, give it to your friends, put it on
club disks (including the disks of Fred Fish of course) and post it to
bulletin boards, as long as you distribute this notice and the example
ARexx scripts with it.
However, this demo version has had save crippled (saving from ARexx
only, no saving of fractal location information, a maximum save size, and a
stripe along the right edge of some pictures), and will occasionally bring
up a text requester to remind you that it is a demo version. The release
version does save of course, and no annoying requesters will appear. See
below for more information on ordering your copy. Additional features that
the release version has include ARexx documentation, much more help, an
AppIcon, and some extra fractal programs, some with source code.
Installation:
To install the Mand2000 demo, make a directory on your hard drive,
or format a floppy disk, and copy the Mand2000D and TweenPlayer programs,
and Mand2000Demo.help to that directory. This can be done by just dragging
the icons to the drawer using Workbench. Then you should copy the ARexx
scripts to your rexx: directory. Even if you don't program in ARexx you
should still copy these scripts because they add some very nice menu
commands. To copy the ARexx scripts to rexx: simply double click on the
InstallRexx icon.
The TweenPlayer is for playing TweenMovies, which are created from
the `Make zoom movie' menu in Mand2000D. Read the online help for further
information.
Description:
What is Mand2000?
Mand2000 is meant to be nothing less than the finest Mandelbrot
exploration program available on any computer. We have attempted to
combine speed, power and simplicity with a few unique features, all
designed to make it easy for you to discover uncharted regions of the
Mandelbrot and Julia sets.
What makes Mand2000 different?
Point and click animated zooming is the most intuitive way of
exploring the Mandelbrot and Julia sets that we could think of. It's as
easy as using a zoom lens on a camera. And to the best of our knowledge no
one else uses this method.
Until now the idea of driving through the Mandelbrot set would have
been absurd - now it's a reality. Plug in your joystick and scroll and
zoom your way around the most complex object ever seen.
Mand2000's multi-pass drawing means that even slower Amigas can take a
test drive. It lets you see roughly what the final picture is going to
look like in mere seconds - even for pictures that will take several
minutes to complete. This allows you to decide almost instantly whether to
keep zooming, or wait for the completed picture.
Morphing is pretty trendy today, but you'll probably still be
surprised to hear that Mand2000 has a morph option. Create stunning
animations of the Mandelbrot set smoothly morphing into a circle.
Mand2000 also lets you make Mandelbrot Zoom movies. Instead of
wasting time, disk space, and memory to calculate every frame in the
animation, Mand2000 optionally calculates the key frames and fills in the
intermediate frames at playback. The result: Movies are calculated about
ten times faster and take far less space on disk. And, since Mand creates
postage stamp versions of your images to use as icons, you can see what
your animations will look like, as soon as you open a directory.
Once Mand2000 has created a series of pictures, and icons for them,
you can use Workbench to create a tiny flip movie to show you what the real
movie will look like. Open up the drawer that the frames are in, and size
it so that it's only tall enough for one icon. Then select `clean up' from
the Workbench menus and all of the icons should line up in a row. Now size
the window so that it's a bit wider than the individual icons, and then
click in the body of the horizontal scroll bar. Workbench will display the
next icon. Repeated clicking plays the movie! Silly? Probably. You
decide.
Another first for Mand2000 is the Show Location menu function. If
you're zoomed way into the Mandelbrot set, it can be very easy to forget
where in the set you are, and very difficult to find out. Show location
makes it easy by opening up another fractal window and displaying your
location in it. You can watch the box move as you zoom and scroll, or you
can zoom the new window in for a more precise view of where you are. This
invaluable feature makes it orders of magnitude easier to find the many
relationships between shapes and locations in the Mandelbrot set, and makes
discovering the relationships between Mandeblrot and Julia sets easy.
Mand2000 has a very sophisticated multi-window, multi-requester
design. You can adjust parameters and see the changes in real time as
Mand2000 continues calculating while you use the requesters. Leave as many
requesters open as you want. Leave as many fractal windows open as you
want.
Mand2000 is also one the only program we know of that has the tested
capability to zoom in on a Mandelbrot set one thousand times (magnification
of 10 to the three hundredth). We know it can. We did it!
Mand2000 is fast. We won't claim that it is the fastest, because
there is always some smart kid out there waiting to prove you wrong when
you make that claim. But we believe that Mand2000's zoom animation,
iteration count preservation, multi-pass drawing, constant calculating and
other features make it usually the fastest one in real world tests.
Just a few of the other features include: literally dozens of
different math routines for accuracies ranging from 16 bit to 1000+ bits,
with separate versions custom coded for 68000, 68020, 68040 and 68881, a
very comprehensive on-line help, printing, multi-level undo, built in
locations to start you searching, full featured ARexx support and a lot of
other things not available in the demo version.
These are just some of the more significant and innovative features in
Mand2000. There are dozens more, all tightly crafted and seamlessly tied
together with a level of quality you would expect to pay hundreds of
dollars for. We will accept such payments, or will settle for $34.95 sent

How do you use Mand2000?
To start using Mand2000, the simplest thing to do is to place the
mouse over an interesting area, one of the areas with lots of detail, and
then double click the left mouse button. The picture will zoom in, placing
the area under the mouse in the centre of the screen. You can continue
doing this as many times as you like, searching for interesting areas. To
zoom out press `D'. To scroll the picture around, hold down the left mouse
button and drag, use the arrow keys, the numeric keypad, or a joystick.
For full information on how to use Mand2000, read the help associated
with the individual menu items. Just highlight a menu item and press the
help key or press the help key any time a requester is active.
Mand2000 runs on all Amigas with AmigaDOS 2.0 or higher. It has been
tested for compatability on Amiga 2000s, 3000s, 4000s, 500s and 1200s, with
68000, 68020, 68030 and 68040 processors, and should run on all other
models as well.
History:
Cygnus Software's first product was MandFXP, the first fixed point
fractal program for the Amiga. MandFXP was the first fractal program to
run at usable speeds, even on a 68000. At the time, in 1986, it was quite
an impressive product and was very popular.
Cygnus Software's next product was CygnusEd. CygnusEd is a high
performance text editor, featuring what is probably still the fastest
scrolling and text rendering of any editor on the Amiga today. Add to that
such invaluable features as unlimited undo, etc., etc. Version 3.5 of
CygnusEd was extensively updated to take advantage of the features that 2.0
has to offer. 3-D gadgets, public screens, the standard file, font and
screen requesters, and the full AGA screen resolutions. Meanwhile CygnusEd
still maintains full compatibility with version 1.3 of the operating
system, bringing the 3-D gadgetry to 1.3. CygnusEd 3.5's macro and
configuration files and ARexx scripts are almost 100% compatible with
earlier versions. CygnusEd is published by ASDG Inc., and is available in
Amiga stores for a suggested retail price of $119.95. Remember, although
CygnusEd was written by Cygnus Software, it is sold through ASDG, and NOT
through Cygnus Software.
Mand2000 was created with CygnusEd and Aztec C.
And now Mand2000. A brand new fractal program, written from
scratch to take advantage of all that the new brand of Amigas have to
offer. Mand2000 takes full advantage of floating point units. It makes
use of the thirty-two bit multiply instructions of the 68020 processors and
above. And it even has special optimizations aimed specifically at the
68040 processor. But while Mand2000 has been optimized to take full
advantage of the most powerful processors available for the Amiga, it has
also been optimized for 68000 processors. All of the calculations run
faster than those in MandFXP. Add to that the vastly improved user
interface with multiple windows, multi-tasking requesters, animated zooms
and many more functions and you have a clearly superior fractal exploration
program. And of course it has an ARexx interface.
We truly believe that Mand2000 is the next step in fractal
exploration.
Enjoy!
