Detailed Description

abstract class to specify dataset behavior

vtkDataSet is an abstract class that specifies an interface for dataset objects. vtkDataSet also provides methods to provide informations about the data, such as center, bounding box, and representative length.

In vtk a dataset consists of a structure (geometry and topology) and attribute data. The structure is defined implicitly or explicitly as a collection of cells. The geometry of the structure is contained in point coordinates plus the cell interpolation functions. The topology of the dataset structure is defined by cell types and how the cells share their defining points.

Attribute data in vtk is either point data (data at points) or cell data (data at cells). Typically filters operate on point data, but some may operate on cell data, both cell and point data, either one, or none.

Retrieve an instance of this class from an information object.

static vtkDataSet* vtkDataSet::GetData	(	vtkInformationVector *	v,
		int	i = `0`
	)

static

Retrieve an instance of this class from an information object.

virtual vtkFieldData* vtkDataSet::GetAttributesAsFieldData ( int type )

virtual

Returns the attributes of the data object as a vtkFieldData. This returns non-null values in all the same cases as GetAttributes, in addition to the case of FIELD, which will return the field data for any vtkDataObject subclass.

Reimplemented from vtkDataObject.

virtual vtkIdType vtkDataSet::GetNumberOfElements ( int type )

virtual

Get the number of elements for a specific attribute type (POINT, CELL, etc.).

Reimplemented from vtkDataObject.

bool vtkDataSet::HasAnyGhostCells ( )

Returns 1 if there are any ghost cells 0 otherwise.

bool vtkDataSet::HasAnyGhostPoints ( )

Returns 1 if there are any ghost points 0 otherwise.

virtual bool vtkDataSet::HasAnyBlankCells ( )

inlinevirtual

Returns 1 if there are any blanking cells 0 otherwise. Blanking is supported only for vtkStructuredGrid and vtkUniformGrid

Reimplemented in vtkStructuredGrid, and vtkUniformGrid.

Definition at line 341 of file vtkDataSet.h.

virtual bool vtkDataSet::HasAnyBlankPoints ( )

inlinevirtual

Returns 1 if there are any blanking points 0 otherwise. Blanking is supported only for vtkStructuredGrid and vtkUniformGrid

Reimplemented in vtkStructuredGrid, and vtkUniformGrid.

Definition at line 349 of file vtkDataSet.h.

vtkUnsignedCharArray* vtkDataSet::GetPointGhostArray ( )

Gets the array that defines the ghost type of each point. We cache the pointer to the array to save a lookup involving string comparisons

void vtkDataSet::UpdatePointGhostArrayCache ( )

Updates the pointer to the point ghost array.

vtkUnsignedCharArray* vtkDataSet::AllocatePointGhostArray ( )

Allocate ghost array for points.

vtkUnsignedCharArray* vtkDataSet::GetCellGhostArray ( )

Get the array that defines the ghost type of each cell. We cache the pointer to the array to save a lookup involving string comparisons

void vtkDataSet::UpdateCellGhostArrayCache ( )

Updates the pointer to the cell ghost array.

vtkUnsignedCharArray* vtkDataSet::AllocateCellGhostArray ( )

Allocate ghost array for cells.

virtual void vtkDataSet::ComputeScalarRange ( )

protectedvirtual

Compute the range of the scalars and cache it into ScalarRange only if the cache became invalid (ScalarRangeComputeTime).

Reimplemented in vtkStructuredGrid, and vtkUniformGrid.

bool vtkDataSet::IsAnyBitSet	(	vtkUnsignedCharArray *	a,
		int	bitFlag
	)

protected

Helper function that tests if any of the values in 'a' have bitFlag set. The test performed is (value & bitFlag).
