Mandelplot V2.4 (17/8/93)
---------------
Documentation for Unregistered version
--------------------------------------
Important: This documentation covers only the very simplest features of the
--------- program. For complete documentation you must register (see
registration.doc)
Introduction: Mandelplot is a fractal generation program. Unlike almost all
------------ other fractal programs for the Amiga, Mandelplot doesn't just
produce 2D images of the Mandelbrot set - Mandelplot was inspired by
'Fractint' on the PC and like Fractint it is a complete fractal package-
You can generate many different fractal types, view them in 2D or 3D,
make animations, and even design your own fractals with the formula editor.
Mandelplot is also the fastest program of its kind on the Amiga- all the
fractal algorithms have been individually written in highly optimised
machine code. Eg the basic Mandelbrot set takes just over 5 seconds to
generate on an old 1.2 1MB A500 and only 1.4 seconds on my 6MB 1200.
Installation: Mandelplot should run on any Amiga with at least 1MB memory
------------ although it has only been tested on a 1MB A500 (from floppy)
and on a 6MB A1200 (3.0) (from a 60 MB HDD).
Running from Floppy or hard disk: The main file 'Mandelplot' must be
present in a directory assigned as 'Mandelplot:' or must be in the root
directory of a disk named 'Mandelplot'. The fonts 'helvetica' and 'Peridot'
must be present in a directory assigned as 'fonts:'. These are the only
requirements for the program to run, although the following directories/
assigns should be present:
Mandelplot:FraFile } contains fractal pictures
Mandelplot:IFS } contains data files for IFS fractal type
Mandelplot:User_Functions } contains formula files
S: } preferences file written here
Getting Started: The program should have been supplied to you on an auto-
--------------- booting disk that loads to a workbench screen. To start it
up, simply double click on the disk icon, then on the Mandelplot icon.
Press the left mouse button to skip the information window that appears,
and the program will begin to draw a mandelbrot set fractal. After a couple
of seconds, the image will be complete, and the main menu will appear.
You can use the right mouse button to toggle this menu on/off or select an
option from the menu by clicking in the box to its right with the left
button.
Interrupting fractal generation: Press the left mouse button at any time
when a fractal is being drawn to interrupt this process and bring up the
main menu.
Zooming in on a fractal image: Use the right button to close the menu screen,
then drag a zoom box over an interesting area of the fractal with the left
mouse button. Press space to redraw this area at full screen size.
Generating a new fractal image: Bring up the menu with the right button.
Select the 'Select fractal type' option to bring up a list of the available
fractal types. Simply select the desired fractal type and it will be drawn
on the screen. Only those types in white are selectable on this version.
The others are only available on the full version, which you can obtain
by registering (see registration.doc).
Increasing the detail level: When you have zoomed some way into a fractal,
the image may appear to lack detail and have many black areas. This
probably means that you need to increase the detail level. Select 'Change
detail level' from the main menu, and double the value of 'Max iters'. This
should reveal new detail, but will increase the generation time.
Loading/Saving fractal files: Mandelplot loads/saves fractal images as a
standard DPaint compatable IFF ILBM file with a separate data file
containing all the fractal information. This extra file enables you to
reload a saved image and redraw it/zoom into it etc. To load or save an
image, select the appropriate option from the main menu and enter the
file name and path into the file requester.
Changing resolution: The default mode for Mandelplot is low-res, 32 colours.
All of the standard Amiga screen modes (not AGA or ECS) are supported, and
can be selected using the 'Select screen mode' option. Support for the AGA
chipset will be included in the very near future, but will only be available
to registered users.
Animation: Generating nice animations is easy with Mandelplot. Generate and
save two different .FRA files to form the first and last frames of the
animation, set the total number of frames, and Mandelplot will
automatically generate and save the in between images. Eg. if the first
frame was the mandelbrot set and the last a zoom in on the mandelbrot
set, the result will be a collection of images zooming smoothly into the
mandelbrot set. To make an animation, these frames must be loaded into
DPaint III or similar and played as an anim from there. Mandelplot has
an intelligent animation routine and will smoothly vary ANY parameter that
varies between the first and last frames, so you can easily generate:
zoom ins, rotating 3D fractals, warping fractals, and many others!
Floppy disk users: Because of the space needed for animations, adopt this
procedure: format a floppy, save the first & last frames on this disk, and
also select this disk as the output path for the anim frames. This will
ensure that sufficient room is available.
NOTE - in this version, anims are restricted to <=16 frames in length. This
resriction is of course not present in the complete version.
Other options: There are loads of features which are not explained in this
document- the palette editing options/ colour control/ the 'Auto' mode/
different drawing modes/ 3D options/etc... if you wish to use these
features, you will either have to figure out how to use them yourself
or register, in which case you will receive the complete documentation.

The fractal routines and algorithms for 'Mandelplot' was written
using HiSoft's excellent Devpac 3, and the user interface was written
using Amos Pro and the Amos Pro Compiler.
Thanks to the Stone Soup Group for writing the superb (for a PC program)
'Fractint' which was the inspiration for Mandelplot.
