Syntax
public sealed class NurbsCurveKnotList : IEnumerable<double>, IEnumerable, IEpsilonComparable<NurbsCurveKnotList>, IList<double>, ICollection<double>The NurbsCurveKnotList type exposes the following members.
Properties
Name
Description
Public Property
Count
Total number of knots in this curve.
Public Property
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.
Public Property
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.
Public Property
Item
Gets or sets the knot vector value at the given index.
Public Property
KnotStyle
Gets the style of the knot vector.
Methods
Name
Description
Public Method
ClampEnd
Clamp end knots. Does not modify control point locations.
Public Method
Contains
Returns an indication of the presence of a value in the knot list.
Public Method
CopyTo
Copies the list to an array.
Public Method
CreatePeriodicKnots
Compute a clamped, uniform, periodic knot vector based on the current degree and control point count. Does not change values of control vertices.
Public Method
CreateUniformKnots
Compute a clamped, uniform knot vector based on the current degree and control point count. Does not change values of control vertices.
Public Method
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.
Public Method
EpsilonEquals
Checks that all values in the other list are sequentially equal within epsilon to the values in this list.
Public Method
Equals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public Method
GetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public Method
GetType
Gets the Type of the current instance.
(Inherited from Object.)
Public Method
IndexOf
Returns the first item in the list.
Public Method
Code Example
InsertKnot(Double)
Inserts a knot and update control point locations. Does not change parameterization or locus of curve.
Public Method
InsertKnot(Double, Int32)
Inserts a knot and update control point locations. Does not change parameterization or locus of curve.
Public Method
KnotMultiplicity
Get knot multiplicity.
Public Method
RemoveKnotAt
Remove a knot from a curve and adjusts the remaining control points to maintain curve position as closely as possible.
Public Method
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.
Public Method
RemoveMultipleKnots
Remove multiple knots from this curve.
Public Method
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.

Public Method
ToString
Returns a string that represents the current object.
