Detailed Description

A Nurbs surface is a type of parametric geometry.

A Nurbs surface is defined by the degree, form, knot vector and control points in the U and V directions.

For more information on the meaning of the form, knot vector and control points, see the documentation for theKFbxNurbsCurve. The same rules for the Nurbs curves apply to Nurbs surfaces. Nurbs surfaces simply have two dimensions (U and V).
