If the tree control you're referring to is like most 2D UI tree controls, then each node can have only one parent. This is not the case in OSG, nodes can have multiple parents. So you'll need to figure out a way to represent this. Paul Martz Skew Matrix Software LLC

I don't believe there is support for OpenGL evaluators in OSG, but you could easily do a recursive grep on the source to see for yourself. OpenGL evaluators have been removed from the OpenGL spec as of v3.1. The modern way to do this would be with a geometry shader. Paul Martz Skew Matrix
