Syntax 
public struct NurbSurfaceDefinition

The NurbSurfaceDefinition type exposes the following members.

Properties
  Name Description
Public property ControlPoints Property that represents a collection of 3D control points.
Public property DegreeInU Property that represents the degree in the U direction. High degree values represent flexible surfaces.
Public property DegreeInV Property that represents the degree in the V direction. High degree values represent flexible surfaces.
Public property NumberOfControlPointsInU Property that represents the number of control points in the U direction.
Public property NumberOfControlPointsInV Property that represents the number of control points in the V direction.
Public property PropertiesInU Property that represents properties in the U direction. These properties correspond to a value from the OdGe::NurbSurfaceProperties enumeration.
Public property PropertiesInV Property that represents properties in the V direction. These properties correspond to a value from the OdGe::NurbSurfaceProperties enumeration.
Public property UKnots Property that represents knot vector in the U direction. A knot vector defines a sequence of parameter values that determine where and how the control points affect the surface. Values of knot vector are provided in ascending order, for example: (0, 0, 0, 1, 2, 3, 3, 3) can be valid while (0, 0, 2, 0, 3, 1, 3, 3) cannot be valid.
Public property VKnots Property that represents knot vector in the V direction. A knot vector defines a sequence of parameter values that determine where and how the control points affect the surface. Values of knot vector are provided in ascending order, for example: (0, 0, 0, 1, 2, 3, 3, 3) can be valid while (0, 0, 2, 0, 3, 1, 3, 3) cannot be valid.
Public property Weights Property that represents a collection of weight values. The weight collection is a collection of double values, each value is associated with a corresponding control point. If the weight increases, the surface pulls toward the corresponding control point. If the weight decreases, the surface pushes from the corresponding control point.
