is the Hypercube 98 software. The program shows tumbling four-dimensional
hypercubes, as well as some 3D polyhedra, and some 2D snowflakes.
A preliminary version of the program (with only the snowflakes and
polyhedra) was developed by Rucker with his CS 116A Computer Graphics
class at SJSU, Spring 1996. As part of her CS Master's degree Writing
Project, Farideh Dormishian added hypercubes to the program and
improved it in other ways.
The original inspiration for the program was Rucker's
desire to reproduce the appearance of snowflakes he saw falling
outside his daughter Georgia's window during a visit to her apartment
in NYC, March, 1996. Then Rucker and Farideh Dormishian had the
idea that the window could just as well look out into hyperspace.
There have been a number of programs which show tumbling wire-frame
hypercubes. A difficult part of what Farideh Dormishian did was
to get the hypercubes to appear with solid faces. The reason
this is difficult is that a tumbling hypercube repeatedly turns
itself "inside-out", which makes hidden-face removal
a bit tricky.
This is a special shareware release
of the software. The program may be freely recopied, but may not
be commercially used or resold without written permission from
Rudy Rucker. You can contact Rucker as: email@example.com.
to unzip hypercube98.zip to your root directory, it will make
a Hypercube 98 directory with the files.
