GetKnotPoints Method (ISplineParamData)

Gets the knot vector for the spline.

.NET Syntax

Visual Basic (Declaration) 
Function GetKnotPoints( _
   ByRef KnotPoints As System.Object _
) As System.Boolean
Visual Basic (Usage) 
Dim instance As ISplineParamData
Dim KnotPoints As System.Object
Dim value As System.Boolean
value = instance.GetKnotPoints(KnotPoints)
System.bool GetKnotPoints( 
   out System.object KnotPoints
System.bool GetKnotPoints( 
&   [Out] System.Object^ KnotPoints


Array of double values between 0 and 1, inclusive (see Remarks)

Return Value

True if successful, false if not



Before calling this method, call ISplineParamData::KnotPointsCount to get the size of the KnotPoints array.

Together with control points, knots determine the shape and smoothness of a spline. The knot vector divides the parametric space into intervals or knot spans. These intervals may be uniform or non-uniform. Each interval governs a different control point.
