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