Detailed Description
Abstract Base Class for poly attributes. One or more poly attribute objects of the same category can be contained and activated at the same time by a rendering engine. Thus, poly attribute objects represent sets of attributes. For example, light sources are poly attributes.poly attributes in a rendering engine can also be temporarily disabled or enabled using Switch objects.

specifies whether the poly attribute is applied globally or locally
Global attributes are applied at the beginning of each maintraversal and unapplied after each maintraversal. For the user, they appear to be active for the whole scene graph. Other poly attributes are applied and unapplied locally in main rendering passes. For global polyattributes, the engine remembers the modelview-transformation in the pretraversal. This requires that any instance of a global attribute must be present only once in the scene graph.
Most poly attributes are local, but some default to global.
