Detailed Description

Filter to unify gradient implementations for different types.

This is a subclass of vtkGradientFilter that allows to apply gradient filters to different structure types through a unique filter. In practice, vtkGradientFilter can be applied to any vtkDataSet. For unstructured grids, the gradient is computed using the cell derivatives, while for structured grids, central differencing is used, except on the boundaries of the dataset where forward and backward differencing is used for the boundary elements. For vtkImageData, it is possible to use the vtkImageGradient implementation. Note that vtkImageGradient always uses central differencing by duplicating the boundary values, which has a smoothing effect. This can be done by setting the boundary handling method to 'SMOOTHED'.

Member Typedef Documentation

◆ Superclass

typedef vtkGradientFilter vtkPVGradientFilter::Superclass

Definition at line 30 of file vtkPVGradientFilter.h.

Member Enumeration Documentation

◆ BoundaryMethod

enum vtkPVGradientFilter::BoundaryMethod

Possible values for gradient computation at boundaries for vtkImageData:

SMOOTHED - Boundary values are duplicated to apply central differencing on the boundary elements.
NON_SMOOTHED - Forward or backward differencing is used on the boundary elements by using their only neighbor.

Get/Set the mode used to compute the gradient on a vtkHyperTreeGrid.

Reminder: in the context of HyperTreeGrids, possible values for gradient computation are:

UNLIMITED - Neighborhood is virtually refined so coarser cells have limited impact on finer ones.
UNSTRUCTURED - Coarser cells are processed as is and may have a greater weight than finer cells. The default is set to UNLIMITED.

◆ GetHTGMode()

virtual int vtkPVGradientFilter::GetHTGMode ( )

virtual

Get/Set the mode used to compute the gradient on a vtkHyperTreeGrid.

Reminder: in the context of HyperTreeGrids, possible values for gradient computation are:

UNLIMITED - Neighborhood is virtually refined so coarser cells have limited impact on finer ones.
UNSTRUCTURED - Coarser cells are processed as is and may have a greater weight than finer cells. The default is set to UNLIMITED.

◆ SetHTGExtensiveComputation()

virtual void vtkPVGradientFilter::SetHTGExtensiveComputation ( bool )

virtual

Get/Set the extensiveness mode used to compute the gradient on a vtkHyperTreeGrid.

This parameter only work in UNLIMITED mode. HTGExtensiveComputation is meant to reduce the influence of an attribute as the corresponding cell is virtually subdivided. The default is set to false.

◆ GetHTGExtensiveComputation()

virtual bool vtkPVGradientFilter::GetHTGExtensiveComputation ( )

virtual

Get/Set the extensiveness mode used to compute the gradient on a vtkHyperTreeGrid.

This parameter only work in UNLIMITED mode. HTGExtensiveComputation is meant to reduce the influence of an attribute as the corresponding cell is virtually subdivided. The default is set to false.

◆ HTGExtensiveComputationOn()

virtual void vtkPVGradientFilter::HTGExtensiveComputationOn ( )

virtual

Get/Set the extensiveness mode used to compute the gradient on a vtkHyperTreeGrid.

This parameter only work in UNLIMITED mode. HTGExtensiveComputation is meant to reduce the influence of an attribute as the corresponding cell is virtually subdivided. The default is set to false.

◆ HTGExtensiveComputationOff()

virtual void vtkPVGradientFilter::HTGExtensiveComputationOff ( )

virtual

Get/Set the extensiveness mode used to compute the gradient on a vtkHyperTreeGrid.

This parameter only work in UNLIMITED mode. HTGExtensiveComputation is meant to reduce the influence of an attribute as the corresponding cell is virtually subdivided. The default is set to false.
