Class LightBin

java.lang.Object

javax.media.j3d.LightBin

All Implemented Interfaces:

ObjectUpdate

 class LightBin
extends java.lang.Object
implements ObjectUpdate

The LightBin manages a collection of EnvironmentSet objects. The number of objects managed depends upon the number of Lights in each EnvironmentSet and the number of lights supported by the underlying rendering layer.
