Detailed Description

vtkStructuredGridConnectivity is a concrete instance of vtkObject that implements functionality for computing the neighboring topology within a single partitioned structured grid dataset. This class implementation does not have any support for distributed data. For the parallel implementation see vtkPStructuredGridConnectivity.
