Dim instance As ICurve

Dim value As Object
 
value = instance.GetBCurveParams(WantCubicIn)

object GetBCurveParams( 
   bool WantCubicIn
)

Object^ GetBCurveParams( 
&   bool WantCubicIn
) 

Parameters

WantCubicIn

True returns cubic rational parameters, false does not

Return Value

Array describing the parameters of the curve (see Remarks)

To control the accuracy of the curve data, see IModeler::SetToleranceValue.

The return value is an array of doubles. The array size is ( 2 + numKnots + numControlPointDoubles) where numKnots is (numControlPoints + order). The array is as follows:

[ packedDouble1, packedDouble2, knot1, knot2,..., ControlPoint1[Dimension], ControlPoint2[Dimension],...
]

where:

• packedDouble1 is an integer pair containing the Dimension and Order
• packedDouble2  is an integer pair containing the NumControlPoints and Periodicity
• knot1
• knot2

...

• ControlPoint1[dimension]
• ControlPoint2[dimension]

...

The size of the control point array is based on the curve dimension:

• If Dimension = 3, then ControlPoint is an array of 3 doubles ( x, y, z )
• If Dimension = 4, then ControlPoint is an array of 4 doubles ( x, y, z, w ) where
  w = weight
