Purpose

This shape node represents a NURBS surface based on the node’s knot vectors and on control points constructed from the current coordinates.

The current coordinates are used in row-major order (the V direction corresponds to the rows).

The number of coordinates used is determined by the Num UControl Points and Num VControl Points fields.

The UKnot Vector and VKnot Vector fields contain floating point arrays of non-decreasing values.
