[vtkusers] How to communicate between vtkPiecewiseFunctionand vtkDataArray

[Yi-Yu Chou]

Dear  Amy,

Because python doesn't support pointer, I can't use GetDataPointer method 
in my program....
In this situation I must setup a piecewise function for the data array 
without using vtkPiecewiseFunction.
Do you have any idea about how to do it ?
Thanks in advance !!!!

Best,
Yi-Yu
