基于虚拟现实的产品协作设计系统

Virtual Reality Based Collaborative Environment for Effective Product Design

基于虚拟现实的协作设计系统为跨部门、跨地域、跨时区的产品协作设计提供了一个直观、方便的交流平台，可有效缩短产品的设计周期．系统可在PC机上运行，采用VRML、EAI和Java作为系统主干．VRCE支持多视角、多层次的信息交流，采用开放式的系统结构，便于进一步开发．作为一个应用实例，还讨论了游戏操控杆的协作设计．

A Virtual Reality - based Collaboraive Design System is propoed to taluce the pnduct - de-sign life cycle. The system supports corporation between departments or geographically distributed organi-zations. Design problems and key elements of the system, such as multiple visual viewpoints and multiple informaion layers are discussed. A joystick design system, which is a Java and VRML based virtual en-vironment with collaborative visualization, is developed by using EAI to demonstrate Ihe feasibility of the proposed system.
