Documentation

Basic NodeVisitor implementation for rendering a scene. This visitor traverses the scene graph, collecting transparent and opaque osg::Drawables 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::Drawable from the eye to the one nearest the eye.

oinline void pushStateSet(const osg::StateSet* ss)
Push state set on the current state group. If the state exists in a child state group of the current state group then move the current state group to that child. Otherwise, create a new state group for the state set, add it to the current state group then move the current state group pointer to the new state group.

oinline void popStateSet()
Pop the top state set and hence associated state group. Move the current state group to the parent of the popped state group.
