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.).

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.

overridevirtual

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

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, ...).

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.

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.

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).
