Detailed Description

A visitor for traversing a scene graph establishing which OpenGL visuals are required to support rendering of that scene graph.

The results can then be used by applications to set up their windows with the correct visuals. Have a look at src/osgGLUT/Viewer.cpp's Viewer::open() method for an example of how to use it.
