[vtkusers] How to read Scalar data from a vtk file?

[Deepak kumar Premnath]

Hello vtk experts,
 
I have a problem reading Scalar data from a vtk file. I am using the following steps.......Can you correct me if I am wrong....
 
 vtkScalars *scalars = new vtkScalars;
         vtkPolyDataReader *datareader = vtkPolyDataReader::New();
         datareader->SetFileName("argv[2]");
         datareader->SetScalarsName("my_scalars_name");
         datareader->Read(scalars);

I am a starter in vtk....So please bear with me......
 
Thanks,
 
Deepak
