Longfei,

	It is usually a better idea to send the mail to the whole ML you'll get
faster answer.

	To visualize the mesh you need a vtkDataSetMapper. See for example:

VTK/Examples/DataManipulation/Python/pointToCellData.py
or online:
http://public.kitware.com/cgi-bin/cvsweb.cgi/~checkout~/VTK/Examples/DataManipulation/Python/pointToCellData.py

For your second problem you have many option:
- use a vtkGeometryFilter
- use a vtkDataSetSurfaceMapper
- use a vtkFeatureEdge

You'll find all the documentation for these classes here:
