CurveDerivativeAt Method (Double, Int32, CurveEvaluationSide)

Evaluate the derivatives at the specified curve parameter.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)

Since: 5.0

Syntax

public Vector3d[] DerivativeAt(
	double t,
	int derivativeCount,
	CurveEvaluationSide side
)

Public Function DerivativeAt ( 
	t As Double,
	derivativeCount As Integer,
	side As CurveEvaluationSide
) As Vector3d()

t: Type: SystemDouble
Curve parameter to evaluate.
derivativeCount: Type: SystemInt32
Number of derivatives to evaluate, must be at least 0.
side: Type: Rhino.GeometryCurveEvaluationSide
Side of parameter to evaluate. If the parameter is at a kink, it makes a big difference whether the evaluation is from below or above.

Type: Vector3d
An array of vectors that represents all the derivatives starting at zero.
