SurfaceEvaluator.getThirdDerivative Method

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

Description

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

Syntax

"surfaceEvaluator_var" is a variable referencing a SurfaceEvaluator object.

(returnValue, partialUUU, partialVVV) = surfaceEvaluator_var.getThirdDerivative(parameter)
 

#include <Core/Geometry/SurfaceEvaluator.h

// Declare the output arguments.
Ptr<Point2D> parameter;
Ptr<Vector3D> partialUUU;
Ptr<Vector3D> partialVVV;
boolean returnValue = surfaceEvaluator_var->getThirdDerivative(parameter, partialUUU, partialVVV);

Return Value

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

Parameters

Name Type Description
parameter Point2D The parameter position to get the surface third derivative at. The parameter position must be within the range of the parameter extents as verified by isParameterOnFace.
partialUUU Vector3D The output third derivative UUU partial vector at each parameter position specified.
partialVVV Vector3D The output third derivative VVV partial vector at each parameter position specified.
