I have seen a PovRay Emulator that was able to access 3d rendering cards and
have them do some of the math (not rendering) on the povray raytracing.  It
was somewhat faster than a normal CPU.  Has anybody else seen this???

  I wonder how do you calculate the intersection of a ray with a primitive
with a 3D-card. AFAIK, 3D-cards do not support spheres, cylinders, etc.

I have never heard of such a thing, but I can't see how it would work
seeing how pov is a ray tracer and 3D graphics cards do grouand shading.  The
two are apples and oranges.  Although we have a SGI Iris here that can do some
neat thing like shadows and simulated reflections, it is not doing
raytracing.
