Detailed Description

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 is rendered in order from the furthest osg::Drawable from the eye to the one nearest the eye.

virtual

CullVisitor's default clamping of the projection float matrix to computed near and far values. Note, do not call this method directly, use clampProjectionMatrix(..) instead, unless you want to bypass the callback.
