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.). vtkUnstructuredGrid provides random access to cells, as well as topological information (such as lists of cells using each point).

THIS METHOD IS THREAD SAFE

Implements vtkDataSet.

◆ GetCell() [1/5]

vtkCell* vtkUnstructuredGrid::GetCell ( vtkIdType  cellId)
overridevirtual

Get cell with cellId such that: 0 <= cellId < NumberOfCells.

◆ GetCell() [2/5]

void vtkUnstructuredGrid::GetCell ( vtkIdType  cellId,
vtkGenericCell cell

overridevirtual

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.

The list consists of an array of types (not necessarily in any order), with a single entry per type. For example a dataset with 5 triangles, 3 lines, and 100 hexahedra would result in a list of three entries, corresponding to the types VTK_TRIANGLE, VTK_LINE, and VTK_HEXAHEDRON. This override implements an optimization that recomputes cell types only when the types of cells may have changed.

THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED

Reimplemented from vtkDataSet.

◆ GetCellLocationsArray()

inline

Get the array of all the starting indices of cell definitions in the cell array.

Definition at line 215 of file vtkUnstructuredGrid.h.

◆ GetFaceStream() [1/2]

void vtkUnstructuredGrid::GetFaceStream ( vtkIdType  cellId,
vtkIdList ptIds 
)

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, ...).

◆ GetFaceStream() [2/2]

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, ...).

◆ SetCells() [1/4]

void vtkUnstructuredGrid::SetCells ( int  type,
vtkCellArray cells 
)

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.

)

◆ SetCells() [3/4]

)
overridevirtual

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.

◆ InsertNextLinkedCell()

vtkIdType vtkUnstructuredGrid::InsertNextLinkedCell ( int  type,
int  npts,
const vtkIdType  pts[] 
)

Use these methods only if the dataset has been specified as Editable.

See vtkPointSet for more information.

unsigned long vtkUnstructuredGrid::GetActualMemorySize ( )
overridevirtual

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.

◆ ShallowCopy()

void vtkUnstructuredGrid::ShallowCopy ( vtkDataObject src)
overridevirtual

Shallow and Deep copy.

Reimplemented from vtkPointSet.

◆ DeepCopy()

void vtkUnstructuredGrid::DeepCopy ( vtkDataObject src)

◆ GetIdsOfCellsOfType()

void vtkUnstructuredGrid::GetIdsOfCellsOfType ( int  type,
vtkIdTypeArray array

Returns whether cells are all of the same type.

Implements vtkUnstructuredGridBase.

inline

Definition at line 350 of file vtkUnstructuredGrid.h.

◆ InitializeFacesRepresentation()

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 nullptr. In this case, need to initialize the arrays and assign values to the previous non-polyhedron cells.

◆ GetMeshMTime()

virtual vtkMTimeType vtkUnstructuredGrid::GetMeshMTime ( )
virtual

Return the mesh (geometry/topology) modification time.

This time is different from the usual MTime which also takes into account the modification of data arrays. This function can be used to track the changes on the mesh separately from the data arrays (eg. static mesh over time with transient data).
