Detailed Description

layout graph arcs in bundles

This algorithm creates a vtkPolyData from a vtkGraph. As opposed to vtkGraphToPolyData, which converts each arc into a straight line, each arc is converted to a polyline, following a tree structure. The filter requires both a vtkGraph and vtkTree as input. The tree vertices must be a superset of the graph vertices. A common example is when the graph vertices correspond to the leaves of the tree, but the internal vertices of the tree represent groupings of graph vertices. The algorithm matches the vertices using the array "PedigreeId". The user may alternately set the DirectMapping flag to indicate that the two structures must have directly corresponding offsets (i.e. node i in the graph must correspond to node i in the tree).

The vtkGraph defines the topology of the output vtkPolyData (i.e. the connections between nodes) while the vtkTree defines the geometry (i.e. the location of nodes and arc routes). Thus, the tree must have been assigned vertex locations, but the graph does not need locations, in fact they will be ignored. The edges approximately follow the path from the source to target nodes in the tree. A bundling parameter controls how closely the edges are bundled together along the tree structure.

You may follow this algorithm with vtkSplineFilter in order to make nicely curved edges.
