[comp.graphics] 3d graphics using ints

Howdy all.  Was wondering....all the books on 3d graphics I've seen apply
mostly to CAD and engineering work, and thus the proliferation of floats
and doubles.  However, for realtime 3d animation I can't get away with
using floats and doubles and still move graphics real quick (have you
seen some of the pseudo-raytracing used by Dynamix in real time to do
the shading for Red Baron and A10?!) around the screen.  Is their a 
simple way of doing the calculations at high speed without losing too
much accuracy?

Thanks,

Brian
