SurfaceEvaluator.getThirdDerivatives Method

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

Description

Get the third derivatives of the surface at the specified parameter positions.

Syntax

"surfaceEvaluator_var" is a variable referencing a SurfaceEvaluator object.

(returnValue, partialsUUU, partialsVVV) = surfaceEvaluator_var.getThirdDerivatives(parameters)
 

#include <Core/Geometry/SurfaceEvaluator.h

// Declare the output arguments.
Point2D[] parameters;
Vector3D[] partialsUUU;
Vector3D[] partialsVVV;
boolean returnValue = surfaceEvaluator_var->getThirdDerivatives(parameters, partialsUUU, partialsVVV);

Return Value

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

Parameters

Name Type Description
parameters Point2D[] The array of parameter positions to get the surface third derivative at. Each parameter position must be within the range of the parameter extents as verified by isParameterOnFace.
partialsUUU Vector3D[] The output array of third derivative UUU partial vectors at each parameter position specified. The length of this array is equal to the length of the parameters array specified.
partialsVVV Vector3D[] The output array of third derivative VVV partial vectors at each parameter position specified. The length of this array is equal to the length of the parameters array specified.
