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