Compute connected components for a distributed <a class="el" href="a00654.html" title="Base class for graph data types.">vtkGraph</a>. For directed graphs, this computes the connected components; for undirected graphs, this computes the strongly-connected components.
<p>
This VTK class uses the Parallel BGL's implementation of connected components and strongly-connectd components.<p>
