distributed virtual reality (dvr) meaning in English

分布式虚拟实境

Based on the study status at present , the dissertation determines the flight simulation system combined with distributed virtual reality ( dvr ) and traditional simulation methods as the emphasis . according to the basis design principles of dvr , a design scheme of the whole simulation system is proposed . through studying several coordinate systems of the flight dimension and the conversion among them , the article carries out a conversion of the parameters from the flight dimension to the virtual scene
在分析分布式虚拟现实系统基本设计思想的基础上，确立了系统的总体设计方案；深入研究了飞行空间的几种坐标体系及其相互之间的转换，提出了一种将飞行姿态参数转化到虚拟三维空间的变换方法；利用vrml建立了较为完善的三维虚拟飞行场景；分析了vrml动画的产生和与用户交互机制，实现对场景动画的控制；建立了虚拟飞行场景与外部java程序的数据接口，并进一步实现了对远程数据库中飞行数据的访问。
