PREPI can create an input file for the raytracer POVRAY.
You should get this program from

	http://www.povray.org

A number of PREPI users have had problems compiling the offical
version on some SG machines.  If you have problems compiling the
official versions, you can obtain our local precompiled version
(file raytrace.tar.gz), until you can create you own binary from
the official distribution. BUT please read the README-FIRST
file in the directory raytrace.

Example of use:

povray-bmm  input.ray  output_image.rgb  -sizep 1000  -a


Note a linux (redhat) version is included as our Linux 1GHz PIII
is 5x faster than our R5000 O2 !
