## Public Member Functions
| CullBinFrontToBack (const std::string &name, GraphicsStateGuardianBase *gsg, const PStatCollector &draw_region_pcollector)
virtual void | add_object (CullableObject *object, Thread *current_thread)
| Adds a geom, along with its associated state, to the bin for rendering.
virtual void | draw (bool force, Thread *current_thread)
| Draws all the geoms in the bin, in the appropriate order.
virtual void | finish_cull (SceneSetup *scene_setup, Thread *current_thread)
| Called after all the geoms have been added, this indicates that the cull process is finished for this frame and gives the bins a chance to do any post-processing (like sorting) before moving on to draw.

## Detailed Description

A specific kind of CullBin that sorts geometry in order from nearest to furthest based on the center of its bounding volume.

This is useful for rendering opaque geometry, taking optimal advantage of a hierarchical Z-buffer.
