LODmanager initial import

1Overview

4This demo shows an example of the LODManager in action. Every model in the scene
5has its own LodStrips object associated that manages its level of detail.
6Since the scene is highly populated, changing the LOD of every object independently
7would make the performance to fall.
8The LodManager makes efficient LOD computations by reusing previously calculated LODs.
9The level of detail of the objects depends on the distance to the camera. When the
10camera goes away from them, the level of detail decreases, and when the camera gets
11closer to them increases to restore the original geometry of the model.

16IMPORTANT: to notice performance improvements the user must move the camera, since the
17LOD in only re-calculated when the camera position changes.
