<BLOCKQUOTE>
Basic NodeVisitor implementation for rendering a scene.
This visitor traverses the scene graph, collecting transparent and
opaque osg::GeoSets into a depth sorted transparent bin and a state
sorted opaque bin. The opaque bin is rendered first, and then the
transparent bin in rendered in order from the furthest osg::GeoSet
from the eye to the one nearest the eye. </BLOCKQUOTE>
