Syntax

Copy

public sealed class NurbsCurveKnotList : IEnumerable<double>, 
	IEnumerable, IEpsilonComparable<NurbsCurveKnotList>, IList<double>, 
	ICollection<double>

Public NotInheritable Class NurbsCurveKnotList
	Implements IEnumerable(Of Double), IEnumerable, 
	IEpsilonComparable(Of NurbsCurveKnotList), IList(Of Double), ICollection(Of Double)

The NurbsCurveKnotList type exposes the following members.

Properties

	Name	Description
	Count	Total number of knots in this curve.
	IsClampedEnd	Gets a value indicating whether or not the knot vector is clamped at the end of the curve. Clamped curves are coincident with the first and last control-point. This requires fully multiple knots.
	IsClampedStart	Gets a value indicating whether or not the knot vector is clamped at the start of the curve. Clamped curves start at the first control-point. This requires fully multiple knots.
	Item	Gets or sets the knot vector value at the given index.
	KnotStyle	Gets the style of the knot vector.

Methods

	Name	Description
	ClampEnd	Clamp end knots. Does not modify control point locations.
	Contains	Returns an indication of the presence of a value in the knot list.
	CopyTo	Copies the list to an array.
	CreatePeriodicKnots	Compute a clamped, uniform, periodic knot vector based on the current degree and control point count. Does not change values of control vertices.
	CreateUniformKnots	Compute a clamped, uniform knot vector based on the current degree and control point count. Does not change values of control vertices.
	EnsurePrivateCopy	If you want to keep a copy of this class around by holding onto it in a variable after a command completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can call this function as many times as you want.
	EpsilonEquals	Checks that all values in the other list are sequentially equal within epsilon to the values in this list.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IndexOf	Returns the first item in the list.
	InsertKnot(Double)	Inserts a knot and update control point locations. Does not change parameterization or locus of curve.
	InsertKnot(Double, Int32)	Inserts a knot and update control point locations. Does not change parameterization or locus of curve.
	KnotMultiplicity	Get knot multiplicity.
	RemoveKnotAt	Remove a knot from a curve and adjusts the remaining control points to maintain curve position as closely as possible.
	RemoveKnots	Remove knots from a curve and adjusts the remaining control points to maintain curve position as closely as possible. The knots from Knots[index0] through Knots[index1 - 1] will be removed.
	RemoveMultipleKnots	Remove multiple knots from this curve.
	SuperfluousKnot	Computes the knots that are superfluous because they are not used in NURBs evaluation. These make it appear so that the first and last curve spans are different from interior spans. http://wiki.mcneel.com/developer/onsuperfluousknot
	ToString	Returns a string that represents the current object. (Inherited from Object.)
