ReadPolyData

Description¶

vtkXMLPolyDataReader object 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.

An example data set can be found at src/Testing/Data/Torso.vtp.
