This is the initial release of the 4D wireframe viewer that I wrote for
my master's thesis, "Four-Space Visualization of 4D Objects", in May 1991.
The thesis is available via anonymous FTP (try kpc.com), usually under the
name "holl91".  This release should run on platforms that support the GL
language.

    Also available for release via anonymous FTP is my 4D raytracing
program.  Ray4 runs on any platform that supports C and floating point,
but currently the only display programs available are for the Amiga, SGI
platforms, and Sun rasterfiles.
