基于Web的虚拟环境中模型库技术研究

Research on technologies of web-based model database in virtual environment

为在有限的网络带宽条件下进行异地协同虚拟设计,研究开发了一个基于Web的虚拟环境中的模型库管理系统,实现了对模型数据的统一管理并能对异地协同仿真提供支持。通过优化虚拟场景和模型数据,借助键盘、二维鼠标和Spaceball 5000立体鼠标,异地分布的用户可以对模型库中的虚拟对象进行各种实时的交互操作,有助于提高协同设计的质量和效率。

To conduct multi-sited collaborative virtual design under the limited network bandwidth condition; a Web-based Model Database Management System（MDMS） in virtual environment is studied to provide uniform management of model data and support the multi-sited collaborative simulation. By optimizing virtual scenes and model data, multi-sited users can achieve realtime interaction on the virtual objects in the model database via keyboard, 2D mouse or 3D Spaceball 5000 mouse, that can improve the quality and efficiency of collaborative design.
