Actually, everything in Renderman is a polygon.  Even if you use curve 
based objects like spheres, they first get tessellated as polygons 
before being rendered.

I believe Pixar uses a dynamic tessellation which yields polygons 
roughly half the size of individual pixels, so the end quality is still 
quite good, but that doesn't change the fact that the way POV-Ray works 
is very, very different.
