Abstract

This paper presents a multicast approach to shared virtual worlds. A shared VRML world is described with integrated spatial audio in a freeware VRML browser. An implementation in Linux of multicast FreeWRL with the Robust Audio Tool (RAT) is presented. To support this audio-enabled multicast VRML prototype, MVIP (Multicast VRML Interchange Protocol) is implemented as a Java program using the services of the Real-Time Protocol (RTP) and accessing VRML via the External Authoring Interface (EAI).
