[IGSTK-Developers] Scene Graph Visualization Tool

[Patrick Cheng]

Developers,

Thanks for Janakiram and his adviser Kevin Gary from ASU. We now have a 
fully functional and easy to use scene graph tree visualization tool.

You can output the graph to a dot file, or display it on the fly in a 
FLTK GUI.

Below is the sample code demonstrating how easy it is to use this tool.

   // Output to file
   igstk::SceneGraph * sg = igstk::SceneGraph::getInstance();
   sg->ExportSceneGraphToDot("sg.dot");

   // Display it in a window. You need to include igstkSceneGraphUI.h
   sg->ShowSceneGraph(true);
   igstk::SceneGraphUI * sgUI = igstk::SceneGraphUI::getInstance();
   sgUI->DrawSceneGraph(sg);

Thank you,

Patrick
