This shape node represents a NURBS surface based on the knot vectors and the control points that you specify.
The UKnot Vector and VKnot Vector fields specify floating-point arrays of values; the values are the coordinates of the knot points in the surface, and you must enter them in non-decreasing order. The Num UControl Points and Num VControl Points fields specify the number of control points the surface will have in the U and V parametric directions, and will use the current coordinates that are indexed from the Coord Index field.
When default texture coordinates are applied to a NURBS surface, the edges of the texture square are stretched to fit the surface. The axes of the texture are called S and T; S is horizontal and T is vertical. The axes of the NURBS surface are called U and V; U is horizontal and V is vertical. You can also define texture coordinates explicitly with the S,T location point, the knot vectors, and the current texture coordinates.
