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, polyhedron, etc.).

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

virtual

Method allocates initial storage for the cell connectivity. Use this method before the method InsertNextCell(). The array capacity is doubled when the inserting a cell exceeds the current capacity. extSize is no longer used.

Implements vtkUnstructuredGridBase.

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

virtual

Insert/create cell in object by type and list of point ids defining cell topology. Most cells require just a type which implicitly defines a set of points and their ordering. For non-polyhedron cell type, npts is the number of unique points in the cell. pts are the list of global point Ids. For polyhedron cell, a special input format is required. npts is the number of faces in the cell. ptIds is the list of face stream: (numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...) Make sure you have called Allocate() before calling this method

void vtkUnstructuredGrid::GetFaceStream	(	vtkIdType	cellId,

	)

Get the face stream of a polyhedron cell in the following format: (numCellFaces, numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...). If the requested cell is not a polyhedron, then the standard GetCellPoints is called to return a list of unique point ids (id1, id2, id3, ...).

void vtkUnstructuredGrid::GetFaceStream	(	vtkIdType	cellId,
		vtkIdType &	nfaces,
		vtkIdType *&	ptIds
	)

Get the number of faces and the face stream of a polyhedral cell. The output ptIds has the following format: (numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...). If the requested cell is not a polyhedron, then the standard GetCellPoints is called to return the number of points and a list of unique point ids (id1, id2, id3, ...).

void vtkUnstructuredGrid::SetCells	(	int	type,

Special methods specific to vtkUnstructuredGrid for defining the cells composing the dataset. Most cells require just arrays of cellTypes, cellLocations and cellConnectivities which implicitly define the set of points in each cell and their ordering. In those cases the cellConnectivities are of the format (numFace0Pts, id1, id2, id3, numFace1Pts, id1, id2, id3...). However, some cells like vtkPolyhedron require points plus a list of faces. To handle vtkPolyhedron, SetCells() support a special input cellConnectivities format (numCellFaces, numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...) The functions use vtkPolyhedron::DecomposeAPolyhedronCell() to convert polyhedron cells into standard format.

Replace the points defining cell "cellId" with a new set of points. This operator is (typically) used when links from points to cells have not been built (i.e., BuildLinks() has not been executed). Use the operator ReplaceLinkedCell() to replace a cell when cell structure has been built.

virtual

Topological inquiry to get all cells using list of points exclusive of cell specified (e.g., cellId). THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkDataSet.

virtual int vtkUnstructuredGrid::GetPiece ( )

virtual

Set / Get the piece and the number of pieces. Similar to extent in 3D.

virtual int vtkUnstructuredGrid::GetNumberOfPieces ( )

virtual

Set / Get the piece and the number of pieces. Similar to extent in 3D.

virtual int vtkUnstructuredGrid::GetGhostLevel ( )

virtual

Get the ghost level.

unsigned long vtkUnstructuredGrid::GetActualMemorySize ( )

virtual

Return the actual size of the data in kibibytes (1024 bytes). This number is valid only after the pipeline has updated. The memory size returned is guaranteed to be greater than or equal to the memory required to represent the data (e.g., extra space in arrays, etc. are not included in the return value). THIS METHOD IS THREAD SAFE.

Reimplemented from vtkPointSet.

virtual void vtkUnstructuredGrid::ShallowCopy ( vtkDataObject *  src )

virtual

Shallow and Deep copy.

Reimplemented from vtkPointSet.

virtual void vtkUnstructuredGrid::DeepCopy ( vtkDataObject *  src )

virtual

Shallow and Deep copy.

Reimplemented from vtkPointSet.

void vtkUnstructuredGrid::GetIdsOfCellsOfType ( int  type, vtkIdTypeArray *  array  )

virtual

Fill vtkIdTypeArray container with list of cell Ids. This method traverses all cells and, for a particular cell type, inserts the cell Id into the container.

Implements vtkUnstructuredGridBase.

int vtkUnstructuredGrid::IsHomogeneous ( )

virtual

Traverse cells and determine if cells are all of the same type.

Implements vtkUnstructuredGridBase.

void vtkUnstructuredGrid::RemoveGhostCells

(

)

This method will remove any cell that is marked as ghost (has the vtkDataSetAttributes::DUPLICATECELL bit set).

static vtkUnstructuredGrid* vtkUnstructuredGrid::GetData ( vtkInformation *  info )

vtkIdType* vtkUnstructuredGrid::GetFaces

(

vtkIdType

cellId

)

Special support for polyhedron. Return NULL for all other cell types.

vtkIdTypeArray* vtkUnstructuredGrid::GetFaces ( )

inline

Get pointer to faces and facelocations. Support for polyhedron cells.

Definition at line 251 of file vtkUnstructuredGrid.h.

vtkIdTypeArray* vtkUnstructuredGrid::GetFaceLocations ( )

Get pointer to faces and facelocations. Support for polyhedron cells.

Definition at line 252 of file vtkUnstructuredGrid.h.

int vtkUnstructuredGrid::InitializeFacesRepresentation

(

vtkIdType

numPrevCells

)

Special function used by vtkUnstructuredGridReader. By default vtkUnstructuredGrid does not contain face information, which is only used by polyhedron cells. If so far no polyhedron cells have been added, Faces and FaceLocations pointers will be NULL. In this case, need to initialize the arrays and assign values to the previous non-polyhedron cells.

static void vtkUnstructuredGrid::DecomposeAPolyhedronCell ( vtkCellArray *  polyhedronCellArray, vtkIdType &  nCellpts, vtkIdType &  nCellfaces, vtkCellArray *  cellArray, vtkIdTypeArray *  faces  )

static

A static method for converting a polyhedron vtkCellArray of format [nCellFaces, nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...] into three components: (1) an integer indicating the number of faces (2) a standard vtkCellArray storing point ids [nCell0Pts, i, j, k] and (3) an vtkIdTypeArray storing face connectivity in format [nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...] Note: input is assumed to contain only one polyhedron cell. Outputs (2) and (3) will be stacked at the end of the input cellArray and faces. The original data in the input will not be touched.

static void vtkUnstructuredGrid::DecomposeAPolyhedronCell ( vtkIdType *  polyhedronCellStream, vtkIdType &  nCellpts, vtkIdType &  nCellfaces, vtkCellArray *  cellArray, vtkIdTypeArray *  faces  )

static

static void vtkUnstructuredGrid::DecomposeAPolyhedronCell ( vtkIdType  nCellFaces, vtkIdType *  inFaceStream, vtkIdType &  nCellpts, vtkCellArray *  cellArray, vtkIdTypeArray *  faces  )

static

A static method for converting an input polyhedron cell stream of format [nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...] into three components: (1) an integer indicating the number of faces (2) a standard vtkCellArray storing point ids [nCell0Pts, i, j, k] and (3) an vtkIdTypeArray storing face connectivity in format [nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...] Note: input is assumed to contain only one polyhedron cell. Outputs (2) and (3) will be stacked at the end of the input cellArray and faces. The original data in the input will not be touched.

static void vtkUnstructuredGrid::ConvertFaceStreamPointIds ( vtkIdList *  faceStream, vtkIdType *  idMap  )

static

Convert pid in a face stream into idMap[pid]. The face stream is of format [nCellFaces, nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...]. The user is responsible to make sure all the Ids in faceStream do not exceed the range of idMap.

static void vtkUnstructuredGrid::ConvertFaceStreamPointIds ( vtkIdType  nfaces, vtkIdType *  faceStream, vtkIdType *  idMap  )

static

Convert pid in a face stream into idMap[pid]. The face stream is of format [nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...]. The user is responsible to make sure all the Ids in faceStream do not exceed the range of idMap.
