* @brief Read PVTK XML PolyData files.
|
||
|
|
*
|
||
|
|
* vtkXMLPPolyDataReader reads the PVTK XML PolyData file format.
|
||
|
|
* This reads the parallel format's summary file and then uses
|
||
|
|
* vtkXMLPolyDataReader to read data from the individual PolyData
|
||
|
|
* piece files. Streaming is supported. The standard extension for
|
||
|
|
* this reader's file format is "pvtp".
