CurveEvaluator2D.getSecondDerivative Method
Parent Object:
CurveEvaluator2DDefined 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
"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
| boolean |
Returns true if the second derivative was successfully returned. |
Parameters
| 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. |
