VRML 2.0 allows a content creator to dynamically control state
changes in a virtual reality world by defining routes of events over
VRML 2.0 nodes.
In the conceptual execution model defined in the VRML 2.0
specification, an event should be delivered to its destinations
instantaneously. However it makes browser implementation
difficult in routing connections that involve complicated
requirements such as simultaneous events in multiple fields of a
node, or cyclic dependencies between nodes.
This paper describes an event processing method we have
implemented in our VRML browser, which is designed to handle
complicated route connections.
