协同虚拟地理环境中多用户交流交互模式及实现

Study on Collaborative Virtual Geographic Environment System for Multi-User Interaction and Communication

依据现实中人与人之间交往交流以及人与真实环境之间的关系互动方式,结合Internet上用户之间的信息交流手段,建立协同虚拟地理环境中多用户的交流交互模式,并以此为基础设计了协同虚拟地理环境的系统框架结构。以陕西绥德韭园沟小流域淤地坝坝系规划为例,应用JAVAJ、AVA3D、VRML研发了小流域坝系三维协同规划原型系统,并对协同虚拟地理环境中多用户的交流交互方式进行初步实验。

This paper presents a model for multi - user interaction and communication in collaborative virtual geographic environment （CVGE） through analyzing communication modes between people in the real world and interaction between people and environment. Based on this model,a collaborative virtual geographic environment system is designed and developed. The paper adopts the drainage area named Jiuyuangou in Shanxi Provinoe as a case study,and establishes a collaborative system for silt dam planning by JAVA,JAVA3D and VRML. Some rudimental experiments for multi - user interaction and oommunication are carried out within this system.
