I have absolutely no idea about the mathematics involved in NURBS
calculation, but I can speculate and say that those renderers which use
real NURBS (bmrt, renderman) are not raytracers while povray is. Maybe
calculating the intersection of a ray and a NURBS is not easy and/or fast?
I don't know...
(Note: Maybe I'm wrong with bmrt, but AFAIK renderman is not a raytracer)
