Overview
--------

This demo shows an example of the LODManager in action. Every model in the scene
has its own LodStrips object associated that manages its level of detail.
Since the scene is highly populated, changing the LOD of every object independently
would make the performance to fall.
The LodManager makes efficient LOD computations by reusing previously calculated LODs.
The level of detail of the objects depends on the distance to the camera. When the
camera goes away from them, the level of detail decreases, and when the camera gets
closer to them increases to restore the original geometry of the model.

IMPORTANT: to notice performance improvements the user must move the camera, since the
LOD is only re-calculated when the camera position changes.
