If you are looking for good rendering/ray-tracing software, I can
reccomend both Specular's Infini-D, which I was on the Beta test team for,
and Swivel 3-D which doesnt real ray-trace, but does a decent job with
manipulating virtual objects.
To put it all together I suggest MacroMind Director, which I believe
is from Paracomp.
Finally something I can remark on, =)
