Detailed Description

vtkPStructuredGridConnectivity inherits from vtkStructuredGridConnectivity and implements functionality to compute the neighboring topology within a single, partitioned and distributed structured grid dataset.

Warning: Initialize(), ComputeNeighbors() and CreateGhostLayers() are collective operations, every process must call that method.
