Public Structure NurbsData

public value class NurbsData

[<SealedAttribute>]
type NurbsData = 
    struct
        inherit ValueType
    end

The NurbsData type exposes the following members.

Properties

	Name	Description
	Closed	Property that indicates whether the spline is closed. A closed spline is made by creating a smooth spline between the first and last points and joining it with the initial spline.
	ControlPointTolerance	Property that represents the tolerance value used for operating with control points of NURBS.
	Degree	Property that represents the NURBS degree. High degree values make the curve more flexible. For example, a degree of 1 is used to define a segment, and a degree of 2 is used to define a NURBS circle, etc.
	KnotTolerance	Property that represents the tolerance value used for operating with NURBS knots.
	Periodic	Property that indicates whether the spline is periodic.
	Rational	Property that indicates whether the spline is rational. If the spline is rational, each control point has a corresponding weight value.

Methods

	Name	Description
	Equals	Checks objects for equality. (Overrides ValueTypeEquals(Object))
	GetControlPoints	Returns a collection of control points.
	GetHashCode	Retrieves the object hash code. (Overrides ValueTypeGetHashCode)
	GetKnots	Returns a collection of NURBS knots. A knot vector defines a sequence of parameter values that determines where and how the control points affect the curve. The knot vector is a sequence of parameter values and divides the parametric space into intervals, usually called knot spans. Values of the knot vector must be 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) is not valid.
	GetType	Gets the Type of the current instance. (Inherited from Object)
	GetWeights	Returns a collection of NURBS weight values. The closer the weight value is to zero, the closer the curve is to a straight line near the corresponding control point. If the weight increases, the curve pulls toward the corresponding control point. If the weight decreases, the curve pushes from the corresponding control point.
	IsEqualTo(NurbsData)	Checks whether this object is equal to the specified object.
	IsEqualTo(NurbsData, Tolerance)	Checks whether this object is equal to the specified object within the specified tolerance.
	ToString	Returns the fully qualified type name of this instance. (Inherited from ValueType)

Operators

	Name	Description
	Equality(NurbsData, NurbsData)	Equality operator for the NurbsData class.
	Inequality(NurbsData, NurbsData)	Inequality operator for the NurbsData class.
