I have installed Rayshade 4.0 on Athena, for Suns and SGIs. Rayshade
is a freely distributable renderer, that produces images in rle (Utah
Raster Toolkit) output format from input in an internal image
description language. It takes input from stdin, which can be typed in
directly by the user although normally if will be input from an ASCII
file containing commands in the internal language.
To use it, do "add rayshade", followed by commands as explained below.
There is documentation in file /mit/rayshade/distrib/Doc/guide.dvi, in dvi
format (use xdvi to view), and examples in
/mit/rayshade/distrib/Examples. Not all of them seem to work but most
do.
Here is how to generate a very simple test:
echo "sphere 2 0 0 0" | rayshade > sphere.rle
which you can view after rendering is complete by doing "add graphics;
xv sphere.rle".
To render one of the demos, do something like:
cat blob.ray | rayshade > blob.rle
There are lots of command-line options which are documented in the manual.
For Suns, there is also "raypaint", which will render directly into a graphics
image. It follows the same command syntax as rayshade, i.e.:
echo "sphere 2 0 0 0" | raypaint > sphere.rle
