I was looking for some SciVis classes for OSG, along the lines of VTK's very rich collection?
It is possible to use use VTK as a "visualization" engine to prepare data for OSG (vtkActorToOSG), and I am prepared to go that way, but that is not particularly efficient in memory and speed as data has to be translated both ways. I evaluated using either VTK and OSG for a project , but found the VTK scene graph implementation is, in my experience, poorly implemented, and performance is not good once a scene graph gets more than a few levels deep. VTK's abstraction from the underlying graphics API also hurts performance. One of my test cases showed a 20x performance hit over OSG.
