Level Of Detail
A Level of Detail model (LOD) is a lower-resolution version of a game model. The lower-res version is used to improve performance by being swapped in whenever the higher-resolution of the game model is not apparent anymore, for example when it is a certain distance from the player.
LOD Metrics
There are many methods for determining when to swap; the most common is based on distance. Another method is to swap depending on how fast the player is moving, because a player typically won't notice the drop in quality for a fast-moving object. Yet another method is to drop to lower LODs when the framerate drops below a certain number.
LOD Modeling
