Group-level scoping for directional lights, anchors, sensors are handled here. Display lists can optionally be created (but the retain flag is just a hint, not guaranteed). Retained objects can be referred to later to avoid duplicating geometry. OpenGL doesn't allow nested objects. The top-down approach of putting entire groups in display lists is faster for static scenes but uses more memory and means that if anything is changed, the whole object must be tossed.<p>
The bottom-up model wraps each piece of geometry in a dlist but requires traversal of the entire <a class="el" href="classopenvrml_1_1scene.html" title="A scene in the VRML world.">scene</a> graph to reference each dlist. The decision about what groups to stuff in an object is punted to the object itself, as it can decide whether it is mutable.<p>
The OpenGL <a class="el" href="classopenvrml_1_1gl_1_1viewer.html" title="Abstract class for display of VRML models using OpenGL/Mesa.">viewer</a> never puts objects in display lists, so the retain hint is ignored.<p>
