Polyray is a combination of an extensive set of modelling primitives together
with a comprehensive renderer. Models are specified in an ASCII file, which
are then parsed, and subsequently rendered. An IBM-AT or compatible is the
only platform currently supported. An 80386/80387 combination, or 80486 CPU
plus at least 2Mb of RAM is required. (Other CPU/FPU combinations are
available, however the RAM requirement is a minimum.)

Polyray provides a number of distinct features, the most important of which
are the freedom of use of expressions in the modelling file and the ability
to render very complex mathematical surfaces.

There are three archives necessary: plydoc.zip, plydat.zip, and plyexe.zip.
These contain the documents for Polyray, a set of data files, and the
executable.

See the file "quickref.txt", or "polyray.doc" for details on the command
line options and data file syntax.
