box clip filter

ParaView Support

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.

Thanks,
Dave

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.

proxy = GetActiveSource()
proxy.GetClientSideObject().GetClassName()
