[vtkusers] How to communicate between vtkPiecewiseFunction and vtkDataArray

[Amy Henderson]

Hi Yi-Yu,

You can get the underlying double array from the vtkPiecewiseFunction using 
the GetDataPointer method. You can pass this array to a vtkDoubleArray 
using its SetArray method. (You will also need to fill in the size of the 
array and whether vtkDoubleArray is responsible for deleting the double 
array you passed in.)
