RayShade 4.0.6 for 386

This package is provided without any warranty of any kind. Use at your
own risk!

This is the Rayshade ray-tracer, ported to 386 machines running
DOS using the WatCom C/386 Ver.9 compiler. It is compiled with all
optimizations (including the new 486 options).

I have made very few changes to this package, except for the addition
of carriage returns to the original (unix) files, and a few changes
in the source code, marked by __BORLANDC__ and __WATCOMC__.

(Note that Borland C was used only to test-compile, and it is useless
trying to do any rendering in 640k.)

Note the following changes in this 386 version:

- Outputs Targa-24 files instead of MTV or RLE files.

- File names are produced to allow animations. (Output of multiple
Targa-24 output files.

- Targa-24 files are used to input as image maps.
(Make sure your Targa image maps are top-to-bottom type,
or they will appear upside down in the image!)

- Your CPP preprocessor is not used unless you have specified
arguments to CPP with the -P switch. (Original rayshade
always uses CPP.) The settings assumed for CPP are for
Borlands CPP, "-P- -ooutfile" plus whatever settings you
provide with -P.

See the file RAYVM.BAT for setting RAY to use virtual memory. I would
be interested in any images produced with this package, and any stories
of how it ruined your life... Upload images, input files, timings, code
improvements to "The Graphics Alternative" BBS 510-524-2780

Things (for other people) to do:

- Send me lots of images, input files and code improvements
in the mail.
- If RAY hangs, please upload/mail the input file and a description
of how to reproduce the problem.
- Try out some of the rendering options, and tell me what they do.
