// .NAME vtkXMLUnstructuredGridReader - Read VTK XML UnstructuredGrid files.
|
|
// .SECTION Description
|
|
// vtkXMLUnstructuredGridReader reads the VTK XML UnstructuredGrid
|
|
// file format. One unstructured grid file can be read to produce one
|
|
// output. Streaming is supported. The standard extension for this
|
|
// reader's file format is "vtu". This reader is also used to read a
|
|
// single piece of the parallel file format.
