* @class vtkTulipReader
|
||
|
|
* @brief Reads tulip graph files.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* vtkTulipReader reads in files in the Tulip format.
|
||
|
|
* Definition of the Tulip file format can be found online at:
|
||
|
|
* http://tulip.labri.fr/tlpformat.php
|
||
|
|
* An example is the following
|
||
|
|
* <code>
|
||
|
|
* (nodes 0 1 2 3 4 5 6 7 8 9)
|
||
|
|
* (edge 0 0 1)
|
||
|
|
* (edge 1 1 2)
|
||
|
|
* (edge 2 2 3)
|
||
|
|
* (edge 3 3 4)
|
||
|
|
* (edge 4 4 5)
|
||
|
|
* (edge 5 5 6)
|
||
|
|
* (edge 6 6 7)
|
||
|
|
* (edge 7 7 8)
|
||
|
|
* (edge 8 8 9)
|
||
|
|
* (edge 9 9 0)
|
||
|
|
* (edge 10 0 5)
|
||
|
|
* (edge 11 2 7)
|
||
|
|
* (edge 12 4 9)
|
||
|
|
* </code>
|
||
|
|
* where "nodes" defines all the nodes ids in the graph, and "edge"
|
||
|
|
* is a triple of edge id, source vertex id, and target vertex id.
|
||
|
|
* The graph is read in as undirected graph. Pedigree ids are set on the output
|
||
|
|
* graph's vertices and edges that match the node and edge ids defined in the
|
||
|
|
* Tulip file.
|
||
|
|
*
|
||
|
|
* Clusters are output as a vtkAnnotationLayers on output port 1. Each cluster
|
||
|
|
* name is used to create an annotation layer, and each cluster with that name
|
||
|
|
* is added to the layer as a vtkSelectionNode. Nesting hierarchies are treated
|
||
|
|
* as if they were flat. See vtkGraphAnnotationLayersFilter for an example of
|
||
|
|
* how the clusters can be represented visually.
|
||
|
|
*
|
||
|
|
* @attention
|
||
|
|
* Only string, int, and double properties are supported. Display information
|
||
|
|
* is discarded.
|
||
|
|
*
|
||
|
|
* @par Thanks:
|
||
|
|
* Thanks to Colin Myers, University of Leeds for extending this implementation.
