Several people have made valuable contributions towards rend386 by writing
conversion programs that take other file formats and generate .PLG files
that can be read by our demo.

Many thanks to the authors for sharing their work; we encourage others to
do the same.

3ds2plg    -- converts from Autocad 3D Studio to .PLG format
              (contributed by Zap Andersson, author of Raytracker)

irit2plg   -- converts IRIT output files to .PLG format
              (contributed by Gershon Elber, author of IRIT)

off2plg    -- converts OFF files to .PLG format

byu2plg    -- converts Movie BYU files to .PLG format
 
srf2plg    -- converts Surfmodel files to .PLG format

shd2plg    -- converts Sun "shaded" files to .PLG format

combvert   -- combines identical vertices in a .PLG file

dxf2plg    -- converts DXF files to .PLG format (written by Ed Schindler)
              (there is also a file called dxfs3.zip containing DXF data
              to convert)

In all cases, see the comments in the source code for an indication of
command-line options if any.
