To relate this (hypothetically) to POV, we could have:
Object
    Solid
        Infinite
            Plane
        Finite
            Sphere
            Box
            Cone
    Patch
        Poly
        Mesh
        Bicubic

(This is just a start, of course)

Hmm... Perhaps the "Solids" could be divided into prisms (defined by flat
surfaces, not sure what the technical term is) and curves.

...Chambers
