Relationship to NURBS Representation
Rational surfaces are distinct from NURBS Surfaces (and NURBS geometry in general), in that they do not rely on an interpolation to evaluate, but rather an explicit formula. They may, however, be converted to a NURBS representation in many software packages - this translation is sometimes performed automatically, and without alerting the user to the change.
