[vtkusers] Does vtkTransformPolyDataFilter affect original data?

[Wenlong Wang]

Dear all,

I'm using vtkTransformPolydataFilter in my app. According to the documents,
the filter returns a new polydata object with different world coordinates
from the original one.

My question is, is the filter changes the original data as well? And for
the result of the filter, is it being replaced if another transformation is
passed to the filter?

Thank you very much.

Long
