My shareware ray tracer, Vivid, comes with a utility that lets you
combine two images into a red/blue 3d image.  The results are pretty
good.  Maybe I need an option for green?

Since you're talking VGA you've got a possible 64 shades each of red
and green.  That works out to a possible 4096 different colors.  In
practice the 256 colors available with VGA works quite well.
