[vtkusers] display .vtk files in window

[vikrant manne]

Hi Gurujan,
 Trying using the polydata writer. And also re-check if u have used the
Normals before giving the data to  Mapper. Make sure your  last input of the
mapper is same as the input to the Writer.

vtkPolyDataWriter * Writer = vtkPolyDataWriter::New();
Writer->SetFileName("Output_left.vtk");
Writer->SetInput(pNormals_left->GetOutput());
Writer->SetFileTypeToBinary();
Writer->Write();
Writer->Update();

Thanks,
Vikrant Manne
