CurveEvaluator2D.getSecondDerivatives Method

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

Description

Get the second derivatives of the curve at the specified parameter positions.

Syntax

"curveEvaluator2D_var" is a variable referencing a CurveEvaluator2D object.

(returnValue, secondDerivatives) = curveEvaluator2D_var.getSecondDerivatives(parameters)
 

#include <Core/Geometry/CurveEvaluator2D.h

// Declare the output arguments.
double[] parameters;
Vector2D[] secondDerivatives;
boolean returnValue = curveEvaluator2D_var->getSecondDerivatives(parameters, secondDerivatives);

Return Value

Type Description
boolean Returns true if the second derivatives were successfully returned.

Parameters

Name Type Description
parameters double[] The array of parameter positions to get the curve second derivative at. Each parameter value must be within the range of the parameter extents as provided by getParameterExtents.
secondDerivatives Vector2D[] The output array of second derivative vectors at each parameter position specified. The length of this array is equal to the length of the parameters array specified.
