- 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.

- Credits
- -------
-
- 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.
