Overview
--------

This demo shows an example of the LODStrips model in action. The models in the scene
are associated to a LodStrips object that manage their level of detail. 
The level of detail of the objects depend 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 the level of detail increases to restore the original geometry of the
model.

The level of detail begins to decrease at a certain distance of the crowd, and stops
decreasing when the objects reach the their minimum LOD. This 'lodding' distance is
customizable from the source code of the demo.
