[vtk-developers] In Parallel, how to check if data is distributed across nodes.

[Mathieu Westphal]

Hi All

Trying again here with this question.

How can a filter check if an input data is distributed accross nodes in
Parallel ?
I tried to check for CAN_HANDLE_PIECE_REQUEST in my filter
RequestInformation, but without success (with ParaView).

Regards,
