Not the case, at the moment. They may be working towards using the same
language, but I stopped following along. Right now, it isn't there yet.

It would be great, yes. The problem that what POV-Ray requires of a
processor is not what graphics cards provide. When either graphics cards
get complex enough to handle the requirements of a general raytracer, or
someone comes up with an algorithm that works, or someone invests the
time placing all the branching code on the CPU with the matrix math on
the GPU and finds that it does indeed work faster, that is when we may
see POV-Ray start that direction. Not before then, and definitely not
before 4.0.

It is amazing, isn't it?
