Mandelbrot GS source code Released!

[limtc <thyechean@gmail.com>]

Hi,

I accidentally discovered my old Complete Pascal II source code and
program called Mandelbrot GS (and the 2nd one called Mandelbrot II GS,
but I have problem running it in Sweet16). Mandelbrot GS and
Mandelbrot II GS are the best Apple IIGS fractal program at its time
(and might still be the best till now).

I re-release the source code of Mandelbrot GS to public in Virtual GS
Programming site. I also wanted to know what's the best way to release
the S16 program to the Apple IIGS community, so that I can package the
file out in the future.

You can see the non-formatted source code at
http://virtualgs.larwe.com/Virtual_GS_Programming/Mandelbrot_GS.html

You can check the release of this software in 1992:

elcome to the world of Mandelbrot, for the Apple IIGS.

For those who loves my Mandelbrot GS, here are the good news:

I will upload soon to comp.binaries.apple2 TWO new versions of
Mandelbrot
programs!

1. Mandelbrot GS v1.1 - The Mandelbrot program which uses the
traditional
                        algorithm, and with the 4 passes overlay.
                        This new version now supports colour cycling!
                        You can colour cycle in two directions, and
10
                        different speeds.
                        This will be the LAST versions of Mandelbrot
GS.

2. Mandelbrot II GS v1.0 - New, faster, and more features. The second
                           generation of the Mandelbrot GS.
                           This program MIGHT be the fastest
Mandelbrot
                           program for non-accelerated GS. It now
uses
                           the Divide and Conquer algorithm, and has
                           new features like colour cycling (same as
                           Mandelbrot GS v1.1), preview zooming,
better
                           zoom area selection, etc. This program is
                           more than 70% faster than the original.

I dedicate these programs to:

1. My friend John. I hope he can enjoy plotting fractals graphics,
and
   forget all unhappiness.

2. All Apple II developers. Especially Steven Chiang of DreamWorld (He
is
   really a very nice person), Roger Wagner, and all the people
designing
   GNO/ME.

3. All Apple II lovers in the world, especially those who like
Mandelbrot.

Happy Mandelbroting.

Mandelbrot GS provides:

1. Four colour mode.
        Mode 1: Default
                Combination of Repeat and Range modes.
        Mode 2: Repeat
                The colour repeats on alternate value. Best for first
few
                levels.
        Mode 3: Range
                The 15 colours are equally divided. Best for deeper
levels.
        Mode 4: Beauty (prefer)
                This is a totally new mode. The value used is
different from
                the other 3 modes. If you look carefully at the
divergence
                part, it might have a 3D effect.

2. Very fast operation.
        Integer maths instead of SANE is used.

3. 4 overlays to complete the picture.
        That is, you can see the rough picture in 1/4 of the time.

4. No coordination and calculation is needed.

5. Zooming, and the ability to return to first level.

6. Easy to operate.

7. Multiple palettes to select.

8. Automatic mirror image if necessary.

9. Show/hide cursor.
        This is for those who want to save the screen.

10. Show/hide screen.
        This is for those without screen blanker.
