Subject: 3D Parametric Equations - Export math figures to Rotater


This HyperCard stack draws isometric projections of three-dimensional
curves and surfaces (wire-frame). Curves are described with 3 equations in
one parameter, and surfaces with 3 equations in two parameters. The curves
and surfaces can be exported to coordinate files for the freeWare program 
"Rotater" (http://raru.adelaide.edu.au/rotater/).
There are various export options, like choosing between the 7 available
colors, exporting dots or lines and varying the color according to the
z-value of each coordinate. The number of digits after the decimal point
can be chosen between 0 and 20.

Requirements: HyperCard 2.0 (or better) or the HyperCard Player.
