Detailed Description

nice layout of undirected graphs in 3D

vtkGraphLayoutFilter will reposition a network of nodes, connected by lines or polylines, into a more pleasing arrangement. The class implements a simple force-directed placement algorithm (Fruchterman & Reingold "Graph Drawing by Force-directed Placement" Software-Practice and Experience 21(11) 1991).

The input to the filter is a vtkPolyData representing the undirected graphs. A graph is represented by a set of polylines and/or lines. The output is also a vtkPolyData, where the point positions have been modified. To use the filter, specify whether you wish the layout to occur in 2D or 3D; the bounds in which the graph should lie (note that you can just use automatic bounds computation); and modify the cool down rate (controls the final process of simulated annealing).
