[vtkusers] How to extract values of vtkpoint coordinates from vtkXMLPolyDataReader

[Chiranjib Sur]

I think, I have sent this email too quickly. Other than the point
coordinates, if I want to obtain the value of the point attributes, how do
I do that.

I can understand the point coordinates can be obtained by

polydata->GetPoints(Id,desirtedpoint).

What are the alternatives to know the point attributes (scaler/vector) for
the points.

Thanks again,
Chiranjib

Hi,
I want to extract the value of the XMl attributes (e.g. the coordinates of
the VTk points, PointData/Points/DataArray).

I am able to read the file using vtkXMLPolyDataReder and view it in
ParaView but I want to extract values individually.

How do I do that?

Thanks,
Chiranjib
