| LOD - Level-Of-Detail is a group node used to allow applications switching between various representations of objects. |
| The child nodes of LOD represent the same object at varying levels of detail. |
| Which child node is used for the representation of specified object depends on the distance between this object and camera. |
| The representations for higher distances have lower resolution. |
| Use of LOD reduces the number of polygons to be displayed and increases the rendering speed. |
