[vtkusers] vtkXMLPolyDataReader

[Cambridge]

Hi

I have a XML .vtp polydata file (binary) and would like to read it using 
vtkXMLPolyDataReader. I can read the header values correctly but I don't know 
whether the binary data is actually correct. The data contains points and a 
triangulated grid.
How can I check the binary part of the XML file and how can I plot the 
points/polygon mesh?

I use so far

vtkXMLPolyDataReader reader
reader SetFileName "test.vtp"
reader Update

I would appreciate any suggestions.
Thank you!
