Detailed Description

grid connectivity.

A concrete instance of vtkAbstractGridConnectivity that implements functionality for computing the neighboring topology within a structured AMR grid, as well as, generating ghost-layers. Support is provided for 1-D, 2-D (XY,XZ,YZ) and 3-D cell-centered datasets. This implementation does not have any support for distributed data. For the parallel implementation see vtkPStructuredAMRGridConnectivity.
