基于Web的实时虚拟仿真系统研究与实现

RESEARCH AND IMPLEMENTATION ON REAL-TIME VIRTUAL SIMULATION SYSTEM BASED ON WEB

根据真实场景设计数据库,并将场景信息的变化实时地更新到数据库中。将虚拟现实技术和计算机仿真相结合,基于该数据库建立基于Web的实时虚拟仿真系统。实时生成场景过程中,根据真实物体在数据库中的位置信息对场景中的虚拟物体进行定位。此外,采用了VRML与JAVA通信的技术为虚拟场景提供交互功能,使用户可以通过网络查询到场景的实时信息。

A real scene database is set up and updated with the real-time change of the scene, Based on the database,a web-based virtual simulation system is set up by the combination of virtual reality and computer simulation. During the real-time generation of the scene ,the virtual object can be positioned by the data of the database,and then the object model will be put into the position in the virtual scene. The technology of the communication of VRML and JAVA is applied to realize interactive function in the simulation scene,so that the user can get the real-time information of the scene based on Web.
