摘      要：The Virtual Reality Modeling Language (VRML) offers capabilities far beyond the virtual exploration of solid models. The scripting capabilities and the execution mechanism enable the creation of complex applications. Indeed, applications can be implemented as a collection of modules interacting in a decentralized fashion, communicating through the exchange of messages. In this paper, an architecture is presented for creating large VRML worlds. The architecture includes a definition of functional modules that serve as the foundation for applications. In addition, object model architectures are structured into three layers that separate pure behavior from editing controls and also from the interface to the visualization, supporting module diversity and reuse. An urban planning example application is presented that incorporates these ideas and features a graphical user interface (GUI), collision management, a simple simulation manager, and an interface to a web server. Finally, several object examples are described followed by a presentation of an example session.
