Application file:

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 Rotater files, of which the files above are an example. There are various export options, like choosing between the 7 available colours, exporting dots or lines and varying the colour according to the z-coordinate of each point.
