- The BioMorph Program
-
- BioMorph is a program which generates a graph of an eqauation in
- the complex plane. Three equations can be graphed: z^2 + c,
- z^3 + c, and z^5 + c. The constant c can be user specified.
- Complex numbers are used in the equations (i.e., 5 + 3i). The
- graph is 2-D, with real and complex axes. Five preset graph sizes
- are provided, giving various magnifications. In addition, the user
- can select an area of a generated graph with the mouse and create a
- new graph of this indicated area.
-
- Origins of BioMorph
-
- This program was inspired by the Computer Recreations column of the
- July, 1989 issue of Scientific American. Biomorphs are the
- creations of Clifford A. Pickover, a researcher for IBM. They are
- related to both the Julia and Mandelbrot sets.
-
- How to Use BioMorph
-
- Type "biomorph" from the cli to run the program with the default
- constant. To use a different constant type (for example)
- "biomorph 0.5 1.2". To start or stop the current graph, select
- FILE GENERATE or FILE STOP respectively, from the menu. Amiga G and
- Amiga S also work here. The COLORS menu merely changes the tint of
- the graph. The ZOOM menu provides five preset graph magnifications,
- centered on the origin (a great way to return to a recognizable image
- after zooming in to some minute piece of a graph). The EQUATION menu
- lets you select from among the three equations offered.
-
- Sizing the Window
-
- The window can be made larger or smaller, with the graph size varying
- in proportion. A small window generates rapidly and is a good way
- to quickly examine a zoom in. If you find something interesting,
- make the window full size to get the best detail. You might have
- to wait a bit, though! Note that the window can only be made smaller
- when a graph is NOT generating. Select Stop first.
-
- Zooming With the Mouse
-
- If you find a portion of a graph you want to zoom in on, a box can be
- made around it using the mouse. Generating again gives a new graph
- which is the size of this box. To do this, place the mouse at the
- UPPER LEFT of the area which interests you, click and hold the left
- mouse button and drag to the RIGHT. This creates a square shaped
- box which defines the area of the next graph generated. Let go of
- the button to select this area. Select FILE GENERATE to see the
- new graph. If the first box you select isn't quite right, merely
- select a new one before generating.

-
- I hope you enjoy this program. If you have comments, suggestions, bug
- reports, (or a routine for z to the z power) :^) send bixmail to
- cmacdonald.
-
- Give this program to anyone who wants it, but please don't sell it.
