From VRML 2 Scripting -- Java JavaScript VRMLScript CPS616 -- Information Track of CPS -- Spring Semester 97. by Balaji Natarajan(Geoffrey C. Fox) *
Script Nodes essentially give logic and state management to a VRML world.
Key feature of the execution model is that time advances in a VRML 2.0 scene in virtual units
Each time unit in the scene has an associated time value , called a timestamp.
Start of an Event Cascade signifies creation of a timestamp and attaching it to an event.
