CurveEvaluator3D.getSecondDerivative Method

Parent Object: CurveEvaluator3D
Defined in namespace "adsk::core" and the header file is <Core/Geometry/CurveEvaluator3D.h>

Description

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

Syntax

"curveEvaluator3D_var" is a variable referencing a CurveEvaluator3D object.

(returnValue, secondDerivative) = curveEvaluator3D_var.getSecondDerivative(parameter)
 

#include <Core/Geometry/CurveEvaluator3D.h

// Declare the output arguments.
double parameter;
Ptr<Vector3D> secondDerivative;
boolean returnValue = curveEvaluator3D_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 Vector3D The output second derivative vector at the parameter position specified.
