I see strange artifacts at the poles of my sphere and teapot, and I think this is because every so often I get a surfaceNormal that contains invalid floating point values (NaNs). Am I doing something wrong?

Probably not. Whoever wrote the normal-computing code in the NURBS dicer didn’t do something reasonable to handle degenerate cases. If you see flicker-type errors at the poles of the teapot or the sphere as a result of bad normals, ignore them.
