how to set defualt value for vtkProbeFilter?

Hi, teams

I am confused with ‘setting default value for vtkProbeFilter’, can anyone tell me how to do that?

Besides, there is a class named vtkImageProbeFilter in documents, which version have this class and I found that it has a function named " [SetInterpolator]" (

Does vtkProbeFilter has a similar function?
If not, how does vtkProbeFilter do interpolation?

Thank you!

Best regards.
