To create an instance of class vtkUnstructuredGrid, simply invoke its constructor as follows
obj = vtkUnstructuredGrid
obj
is an instance of the vtkUnstructuredGrid class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkUnstructuredGrid = obj.NewInstance ()
vtkUnstructuredGrid = obj.SafeDownCast (vtkObject o)
int = obj.GetDataObjectType ()
- Standard vtkDataSet API methods. See vtkDataSet for more information.
obj.Allocate (vtkIdType numCells, int extSize)
- Standard vtkDataSet API methods. See vtkDataSet for more information.
vtkIdType = obj.InsertNextCell (int type, vtkIdList ptIds)
- Insert/create cell in object by type and list of point ids defining
cell topology.
obj.Reset ()
obj.CopyStructure (vtkDataSet ds)
vtkIdType = obj.GetNumberOfCells ()
vtkCell = obj.GetCell (vtkIdType cellId)
obj.GetCell (vtkIdType cellId, vtkGenericCell cell)
obj.GetCellBounds (vtkIdType cellId, double bounds[6])
obj.GetCellPoints (vtkIdType cellId, vtkIdList ptIds)
obj.GetPointCells (vtkIdType ptId, vtkIdList cellIds)
int = obj.GetCellType (vtkIdType cellId)
vtkUnsignedCharArray = obj.GetCellTypesArray ()
vtkIdTypeArray = obj.GetCellLocationsArray ()
obj.Squeeze ()
obj.Initialize ()
int = obj.GetMaxCellSize ()
obj.BuildLinks ()
vtkCellLinks = obj.GetCellLinks ()
obj.SetCells (int type, vtkCellArray cells)
- Special methods specific to vtkUnstructuredGrid for defining the cells
composing the dataset.
obj.SetCells (int types, vtkCellArray cells)
- Special methods specific to vtkUnstructuredGrid for defining the cells
composing the dataset.
obj.SetCells (vtkUnsignedCharArray cellTypes, vtkIdTypeArray cellLocations, vtkCellArray cells)
- Special methods specific to vtkUnstructuredGrid for defining the cells
composing the dataset.
vtkCellArray = obj.GetCells ()
- Special methods specific to vtkUnstructuredGrid for defining the cells
composing the dataset.
obj.RemoveReferenceToCell (vtkIdType ptId, vtkIdType cellId)
- Special methods specific to vtkUnstructuredGrid for defining the cells
composing the dataset.
obj.AddReferenceToCell (vtkIdType ptId, vtkIdType cellId)
- Special methods specific to vtkUnstructuredGrid for defining the cells
composing the dataset.
obj.ResizeCellList (vtkIdType ptId, int size)
- Special methods specific to vtkUnstructuredGrid for defining the cells
composing the dataset.
obj.GetCellNeighbors (vtkIdType cellId, vtkIdList ptIds, vtkIdList cellIds)
- 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
int = obj.GetUpdateExtent ()
- We need this here to avoid hiding superclass method
obj.GetUpdateExtent (int extent[6])
- We need this here to avoid hiding superclass method
int = obj.GetPiece ()
- Set / Get the piece and the number of pieces. Similar to extent in 3D.
int = obj.GetNumberOfPieces ()
- Set / Get the piece and the number of pieces. Similar to extent in 3D.
int = obj.GetGhostLevel ()
- Get the ghost level.
long = obj.GetActualMemorySize ()
- Return the actual size of the data in kilobytes. 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.
obj.ShallowCopy (vtkDataObject src)
- Shallow and Deep copy.
obj.DeepCopy (vtkDataObject src)
- Shallow and Deep copy.
obj.GetIdsOfCellsOfType (int type, vtkIdTypeArray array)
- 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.
int = obj.IsHomogeneous ()
- Traverse cells and determine if cells are all of the same type.
obj.RemoveGhostCells (int level)
- This method will remove any cell that has a ghost level array value
greater or equal to level.
