* @brief Read VTK XML UnstructuredGrid files.
|
|
*
|
|
* 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.
