Karthik seems to have answered your question, but I have some comments
on your existing code:

Karthik - when you commit this, can you update the example to match/demonstrate?

Dajiang - See inline below:

Where did you find that link? Was it just a mistake? Or does a link
need to be fixed somewhere?

I highly recommend you use smart pointers:
http://www.vtk.org/Wiki/VTK/Tutorials/SmartPointers

vtkSmartPointer<vtkPolyDataReader> TReader =
  vtkSmartPointer<vtkPolyDataReader>::New();

You should NOT create an object before assigning the output of the reader.

Instead, simply do:
vtkPolyData* TsurfaceData = TReader->GetOutput();

Good luck,
