PROGRAMS

As well as defining the type and coordinates of the area, the program produces HTML code for the action required:

3D polar graph

These are functions of the form:-

• z = f(x, y),
• x = f₁(u,v), y = f₂(u,v), z = f₃(u,v)
• r = f(a, b),
• x = f₁(t), y = f₂(t), z = f₃(t)
• r = f₁(t), a = f₂(t), z = f₃(t)
• z = f(r, a),
• y = f(x),
• r = f(a) and
• x = f₁(t), y = f₂(t)

The functions can be plotted with or without axes which can be scaled and the resolution of the graph can be changed to facilitate speed of plotting.

Up to 10 different functions of the same type can be overlaid with each being drawn in a different colour.

The 3D functions can be displayed and printed in one of two stereo forms: stereo-pairs or red/blue anaglyphs.

Functions can be stored and any number of different storage files created. There is also an extensive 'Help' file included.

The package now allows 3D surface plotting with some forms of graph, courtesy of the Surface Viewer control by Bright Ideas Software

z = f(x,y) with hidden lines removed

This version lets you display a particular biomorph and all its relations produced by a change of 1 in each gene value or a set of 25 random mutations from a particular biomorph, as shown on the left.

Each type of display can be printed, either as a grid display or as a full-size biomorph, and they can be saved in storage files of which any number can be created.

A sample storage file is included in the package and there is also an extensive 'Help' file appended.

Julia enlargement

Areas for enlargement are selected by dragging the mouse over a display and displays can be printed and stored, either as the basic data used to generate the display or as the actual display data.

The illustrations are areas of the sets produced by the function z = z˛(z - 1) + c

A sample storage file is included in the package and there is also an extensive 'Help' file appended.

The current version has had a number of modifications added, the most important of which is that you can now enter your own equations.

Mandelbröt enlargement

Data can be entered from the keyboard, generated by commands or imported from Excel workbooks or Access databases.

A simple interpreted language is included to allow the programming of commands.

Data can be stored and re-loaded as can sets of commands or programs.

The package includes an extensive Help file which illustrates the various operations and gives sample programs including that shown in the Command window on the right.
