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