Detailed Description

Define the CellSize field used in vtkHyperTreeGridGenerateFields.

This is a class used by vtkHyperTreeGridGenerateFields to add and compute the CellSize field.

This field is set to the size (volume) of the cell for 3D HTGs, depending on its depth level. This field has a value for every cell traversed through the cursor, valid or not. By extension, CellSize is set to the cell area for 2D HTG and cell length for 1D. In practice, we ignore null size coordinates when computing the value. This field is implemented as an implicit array, in order to lower the memory footprint of the filter.

Member Function Documentation

New()

static vtkHyperTreeGridCellSizeStrategy * vtkHyperTreeGridCellSizeStrategy::New ( )

static

IsTypeOf()

static vtkTypeBool vtkHyperTreeGridCellSizeStrategy::IsTypeOf ( const char *  type )

static

IsA()

virtual vtkTypeBool vtkHyperTreeGridCellSizeStrategy::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

const

PrintSelf()

void vtkHyperTreeGridCellSizeStrategy::PrintSelf ( ostream &  os, vtkIndent  indent  )

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

Initialize() [1/3]

void vtkHyperTreeGridCellSizeStrategy::Initialize ( vtkHyperTreeGrid *  inputHTG )

override

Init internal variables from inputHTG.

Compute() [1/3]

void vtkHyperTreeGridCellSizeStrategy::Compute ( vtkHyperTreeGridNonOrientedGeometryCursor *  cursor )

overridevirtual

Record the depth of the cell pointed by the cursor in an internal structure.

While we have less different size values than an unsigned char can hold, use an index implicit array to save memory. In extreme cases where we cannot (eg. too many levels or custom scales), use a traditional VTK double array. This method does not guarantee thread-safety.

Reimplemented from vtkHyperTreeGridGenerateFieldStrategy.

GetAndFinalizeArray()

vtkDataArray * vtkHyperTreeGridCellSizeStrategy::GetAndFinalizeArray ( )

overridevirtual

If UseIndexedVolume is true, build and return the output as an implicit indexed array.

Otherwise, return the output as a VTK double array.

Implements vtkHyperTreeGridGenerateFieldStrategy.

Initialize() [2/3]

virtual void vtkHyperTreeGridGenerateFieldStrategy::Initialize ( vtkHyperTreeGrid *  vtkMaybeUnusedinputHTG )

inlinevirtual

Reimplement to initialize internal structures based on the given input HTG.

Only one of these methods should be reimplemented:

• If the strategy creates a cell data array, use Initialize with a void return type
• If the strategy creates a field data array, use Initialize with a bool return type

Reimplemented from vtkHyperTreeGridGenerateFieldStrategy.

Definition at line 52 of file vtkHyperTreeGridGenerateFieldStrategy.h.

Initialize() [3/3]

virtual bool vtkHyperTreeGridGenerateFieldStrategy::Initialize ( std::unordered_map< std::string, Field >  )

inlinevirtual

Reimplement to initialize internal structures based on the given input HTG.

Only one of these methods should be reimplemented:

• If the strategy creates a cell data array, use Initialize with a void return type
• If the strategy creates a field data array, use Initialize with a bool return type

Reimplemented from vtkHyperTreeGridGenerateFieldStrategy.

Definition at line 53 of file vtkHyperTreeGridGenerateFieldStrategy.h.

Compute() [2/3]

virtual void vtkHyperTreeGridGenerateFieldStrategy::Compute ( vtkHyperTreeGridNonOrientedGeometryCursor *  )

inlinevirtual

Reimplement to compute the data for the current cell.

Only one of these methods should be reimplemented:

• If the strategy creates a cell data array, use Compute with a single parameter
• If the strategy creates a field data array, use Compute with the extra parameters (they provide the result of the previously computed cell data).

Reimplemented from vtkHyperTreeGridGenerateFieldStrategy.

Definition at line 64 of file vtkHyperTreeGridGenerateFieldStrategy.h.

Compute() [3/3]

virtual void vtkHyperTreeGridGenerateFieldStrategy::Compute ( vtkHyperTreeGridNonOrientedGeometryCursor *  , vtkCellData *  , std::unordered_map< std::string, Field >    )

inlinevirtual

Reimplement to compute the data for the current cell.

Only one of these methods should be reimplemented:

• If the strategy creates a cell data array, use Compute with a single parameter
• If the strategy creates a field data array, use Compute with the extra parameters (they provide the result of the previously computed cell data).
