Hi!

I just finished a small demo I have been working on a couple of months.
It performs real-time ray-tracing and shading (a sort of mixture of them
both) on an IBM PC-compatible computer with VGA graphics. I find it pretty
impressive (although the environment is pretty simple: It has a planet,
a moon and a sun). It runs at 70 frames/second on my 80386/20 Mhz machine.

So, is anybody interested to see this? If so, where should I upload/send
this demo? It is an .EXE program of about 15KB, programmed in assembler
and Turbo Pascal. (Sorry, sources not available, at least not yet :-).

Requirements to run this demo are:
  - VGA-card that is register-compatible with IBM model. (Demo uses the
    non-BIOS-supported 320x400x256 mode).
  - A faster-than-4.77Mhz CPU (though this is not absolutely necessary,
    you probably don't want to view this on a standard PC. :-)

This demo also shows how fast it runs on your computer (frames/second),
so you can use it for testing this also.
