rendering level
 
Hi
how can I reduce details of my world that far away from view point and high details of my world that near to view point?
on the other hand, is it possible to change rendering of detail level of far abjects?
thanks for your help.

Hi shahramy
-One common method is to use fog + distance culling.
-Another option is to use the OSG Level of Detail helper. With this one, you would merge or group all the objects in a room and add it to the LOD helper, then set the distance in meters for that object to be visible. You can set up objects to simply disappear after a certain distance, or you can switch in lower detail versions of the object. These have to be created manually.(Helpers --> OpenSceneGraph --> LOD)
-Vizard does not currently have a way of automatically doing occlusion culling,
but Occluders can be added manually within 3ds max using rectangular splines and the OSG Occluder helper. (Helpers --> OpenSceneGraph --> Occluder)
