No / The authors present the Virtual Park (or VPark) system. This includes a networked virtual environment (NVE) system, called W-VLNET (Windows Virtual Life Network) and an Attraction Building System that creates and modifies attractions used in the NVE system. This article details the techniques for communication, scene management, facial and body animation, and general user interaction modules. The authors used VRML97 and MPEG-4 SHNC to stress the compatibility of the system with other similar virtual reality systems. The software provides realistic virtual actors as well as sets of applicable high-level actions in real time. Using this software, users can introduce their own scenario-based applications into a shared virtual environment.
