box clip filter

What does ParaView use perform a box clip?
I’m using vtkBoxClipDataSet to clip a rectilinear grid in python. It’s quite slow in python, but pretty quick in ParaView. -I get the python vs. c++ performance difference, but wanted to check just in case I was using a less efficient filter to perform the operation.


The best thing to do is check which VTK class is used within ParaView to perform that filter as it might be a different one.
