Parameters

Parameter

Value of the edge parameter

NumberOfDerivatives

Number of derivatives

Return Value

Use IEdge::IGetCurveParams2 to determine the valid parameter range for this method.

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 could 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:

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.
