Detailed Description

dataset represents arbitrary combinations of all possible cell types

vtkUnstructuredGrid is a data object that is a concrete implementation of vtkDataSet. vtkUnstructuredGrid represents any combinations of any cell types. This includes 0D (e.g., points), 1D (e.g., lines, polylines), 2D (e.g., triangles, polygons), and 3D (e.g., hexahedron, tetrahedron).

Member Typedef Documentation

Member Function Documentation

static vtkUnstructuredGrid* vtkUnstructuredGrid::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkDataObject.

virtual const char* vtkUnstructuredGrid::GetClassName ( ) [virtual]

Reimplemented from vtkPointSet.

static int vtkUnstructuredGrid::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkPointSet.

virtual int vtkUnstructuredGrid::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 vtkPointSet.

static vtkUnstructuredGrid* vtkUnstructuredGrid::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkPointSet.

void vtkUnstructuredGrid::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

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 vtkPointSet.

int vtkUnstructuredGrid::GetDataObjectType ( ) [inline, virtual]

Standard vtkDataSet API methods. See vtkDataSet for more information.

Reimplemented from vtkDataSet.

Definition at line 85 of file vtkUnstructuredGrid.h.

virtual void vtkUnstructuredGrid::Allocate	(	vtkIdType	numCells = `1000`,
		int	extSize = `1000`
	)			`[virtual]`

Standard vtkDataSet API methods. See vtkDataSet for more information.

vtkIdType vtkUnstructuredGrid::InsertNextCell	(	int	type,
		vtkIdType	npts,
		vtkIdType *	pts
	)

Insert/create cell in object by type and list of point ids defining cell topology.

vtkIdType vtkUnstructuredGrid::InsertNextCell	(	int	type,
		vtkIdList *	ptIds
	)

Insert/create cell in object by type and list of point ids defining cell topology.

void vtkUnstructuredGrid::Reset ( )

virtual void vtkUnstructuredGrid::CopyStructure ( vtkDataSet * pd ) [virtual]

Copy the geometric structure of an input point set object.

Reimplemented from vtkPointSet.

vtkIdType vtkUnstructuredGrid::GetNumberOfCells ( ) [virtual]

Determine the number of cells composing the dataset. THIS METHOD IS THREAD SAFE

Implements vtkDataSet.

virtual vtkCell* vtkUnstructuredGrid::GetCell ( vtkIdType cellId ) [virtual]

Get cell with cellId such that: 0 <= cellId < NumberOfCells. THIS METHOD IS NOT THREAD SAFE.

Implements vtkDataSet.

virtual void vtkUnstructuredGrid::GetCell	(	vtkIdType	cellId,
		vtkGenericCell *	cell
	)			`[virtual]`

Get cell with cellId such that: 0 <= cellId < NumberOfCells. This is a thread-safe alternative to the previous GetCell() method. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

virtual void vtkUnstructuredGrid::GetCellBounds	(	vtkIdType	cellId,
		double	bounds[6]
	)			`[virtual]`

Get the bounds of the cell with cellId such that: 0 <= cellId < NumberOfCells. A subclass may be able to determine the bounds of cell without using an expensive GetCell() method. A default implementation is provided that actually uses a GetCell() call. This is to ensure the method is available to all datasets. Subclasses should override this method to provide an efficient implementation. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkDataSet.

virtual void vtkUnstructuredGrid::GetCellPoints	(	vtkIdType	cellId,
		vtkIdList *	ptIds
	)			`[virtual]`

Topological inquiry to get points defining cell. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

void vtkUnstructuredGrid::GetPointCells	(	vtkIdType	ptId,
		vtkIdList *	cellIds
	)			`[virtual]`

Topological inquiry to get cells using point. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

int vtkUnstructuredGrid::GetCellType ( vtkIdType cellId ) [virtual]

Get type of cell with cellId such that: 0 <= cellId < NumberOfCells. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Implements vtkDataSet.

void vtkUnstructuredGrid::Initialize ( ) [virtual]

Reset to an empty state and free any memory.

Reimplemented from vtkPointSet.

int vtkUnstructuredGrid::GetMaxCellSize ( ) [virtual]

Convenience method returns largest cell size in dataset. This is generally used to allocate memory for supporting data structures. THIS METHOD IS THREAD SAFE

Implements vtkDataSet.
