I am trying to find documentation on how to access different timesteps of field data within a Python Programmable Filter. (Specifically, I want to output a vtkTable of the cross-correlation sequences of scalar field arrays A and B over all timesteps.)
The only reference I found was this comment : > *I suspect that one will have to add support for RequestInformation and > RequestUpdateData to the programmable filter to support time. That's what > we had to do in the python programmable filter we use with ParaView.* I have found no documentation on what the 'RequestInformation' and 'RequestUpdateData' scripts should look like, and how to use their outputs in the filter. Can someone please post an example of a paraview Programmable Python Filter that accesses the timesteps of field data of its inputs? Many thanks... Dean
