Detailed Description

ActorBase is the base class for all Actors. See PageExperimentalNewActionActorBase for a description.

Ext:

To create a new actor you should use the actorEdit utility that can be found in /OpenSG/Tools/actorEdit. It will generate a base class for your own actor that takes care of the management of functors and state.
