CurveEvaluator2D.getSecondDerivative Method

Parent Object: CurveEvaluator2D
Defined in namespace "adsk::core" and the header file is <Core/Geometry/CurveEvaluator2D.h>

Description

Get the second derivative of the curve at the specified parameter position.

Syntax

Python
C++

"curveEvaluator2D_var" is a variable referencing a CurveEvaluator2D object.

(returnValue, secondDerivative) = curveEvaluator2D_var.getSecondDerivative(parameter)


#include <Core/Geometry/CurveEvaluator2D.h

// Declare the output arguments.
double parameter;
Ptr<Vector2D> secondDerivative;
boolean returnValue = curveEvaluator2D_var->getSecondDerivative(parameter, secondDerivative);

Return Value

Type	Description
boolean	Returns true if the second derivative was successfully returned.

Parameters

Name	Type	Description
parameter	double	The parameter position to get the curve second derivative at. The parameter value must be within the range of the parameter extents as provided by getParameterExtents.
secondDerivative	Vector2D	The output second derivative vector at the parameter position specified.
