Evaluate2 Method (ICoEdge)

Gets the (X,Y,Z) location and the tangency vector on the coedge at the specified position.

.NET Syntax

Visual Basic (Declaration) 
Function Evaluate2( _
   ByVal Param As Double, _
   ByVal NumberOfDerivatives As Integer _
) As Object
Visual Basic (Usage) 
Dim instance As ICoEdge
Dim Param As Double
Dim NumberOfDerivatives As Integer
Dim value As Object
 
value = instance.Evaluate2(Param, NumberOfDerivatives)
C# 
object Evaluate2( 
   double Param,
   int NumberOfDerivatives
)
C++/CLI 
Object^ Evaluate2( 
&   double Param,
&   int NumberOfDerivatives
) 

Parameters

Param

Curve parameter desired (U value desired for evaluation)

NumberOfDerivatives

Number of derivatives

Return Value

Array of doubles (see Remarks)

Remarks

The tangency vector is defined to be in the direction of the coedge.

The format of the return value is an array of (NumberOfDerivatives + 1) * 3 doubles:

[evaluated point], [evaluated derivative 1],...[evaluated derivative NumberOfDerivatives]

In pseudo mathematical notation, this can be written as:

    P(t)  P(t)/dt  P(t)/dtdt ..........

 In terms of the number of derivatives that can be returned for a curve type, you could write:

 

Curve type

Maximum number of derivatives

Line/circle/ellipse

2

Intersection curve

2

Constant parameter line

Determined by underlying surface

SP-curve

2

B-curve

Any number

 

where the curve type is from ICurve::Identity.

For a curve of type swCurveTypes_e::TRIMMED_TYPE, the number of derivatives is determined by the base curve as obtained from ICurve::GetBaseCurve.
