Detailed Description

"Collapses" vertices onto their neighbors.

vtkCollapseGraph "collapses" vertices onto their neighbors, while maintaining connectivity. Two inputs are required - a graph (directed or undirected), and a vertex selection that can be converted to indices.

Conceptually, each of the vertices specified in the input selection expands, "swallowing" adacent vertices. Edges to-or-from the "swallowed" vertices become edges to-or-from the expanding vertices, maintaining the overall graph connectivity.

In the case of directed graphs, expanding vertices only swallow vertices that are connected via out edges. This rule provides intuitive behavior when working with trees, so that "child" vertices collapse into their parents when the parents are part of the input selection.

Convenience function provided for setting the selection input.

int vtkCollapseGraph::FillInputPortInformation ( int  port,
vtkInformation *  info 
)
protectedvirtual

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkGraphAlgorithm.

int vtkCollapseGraph::RequestData ( vtkInformation *  request,
vtkInformationVector **  inputVector,
vtkInformationVector *  outputVector 
)
protectedvirtual

This is called by the superclass. This is the method you should override.

Reimplemented from vtkGraphAlgorithm.
