I think that if you use any material meant to be even the slightest bit transparent, you need this routine, in stills or animations. Just download the demo and you'll see (it has the magnifying glass over VALLEY.TGA). Obviously this thing doesn't do all that ray tracing can do, but when it comes to refraction I can't imagine why anyone would want the overhead of a ray-tracer when this is available (and for a reasonable price).
