SurfaceEvaluator.getSecondDerivative Method

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

Description

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

Syntax

Python
C++

"surfaceEvaluator_var" is a variable referencing a SurfaceEvaluator object.

(returnValue, partialUU, partialUV, partialVV) = surfaceEvaluator_var.getSecondDerivative(parameter)


#include <Core/Geometry/SurfaceEvaluator.h

// Declare the output arguments.
Ptr<Point2D> parameter;
Ptr<Vector3D> partialUU;
Ptr<Vector3D> partialUV;
Ptr<Vector3D> partialVV;
boolean returnValue = surfaceEvaluator_var->getSecondDerivative(parameter, partialUU, partialUV, partialVV);

Return Value

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

Parameters

Name	Type	Description
parameter	Point2D	The parameter position to get the surface second derivative at. The parameter position must be within the range of the parameter extents as verified by isParameterOnFace.
partialUU	Vector3D	The output second derivative UU partial vector at each parameter position specified.
partialUV	Vector3D	The output second derivative UV mixed partial vector at each parameter position specified.
partialVV	Vector3D	The output second derivative VV partial vector at each parameter position specified.
