Detailed Description

a distributed structured dataset that is implicitly connected among partitions without abutting. This creates a gap between partitions and introduces a cell that spans multiple zones. This typically arises with finite difference grids, which are partitioned with respect to the nodes of the grid, or, when a filter samples the grid, e.g., to get a lower resolution representation.

This class is intended as a lower-level helper for higher level VTK filters that provides functionality for resolving the implicit connectivity (gap) between two or more partitions of a distributed structured dataset.

Warning

The present implementation requires:

one block/grid per rank.
2-D (XY,YZ or XZ planes) or 3-D datasets.
node-center fields must match across processes.

static vtkStructuredImplicitConnectivity* vtkStructuredImplicitConnectivity::New ( )

static

void vtkStructuredImplicitConnectivity::PrintSelf	(	ostream &	os,

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.
