摘要
从媒体的角度看待虚拟现实技术的发展,介绍了基于Vega Prime和Creator的虚拟场景漫游系统的结构及其实现流程,并紧紧围绕虚拟场景的真实性和系统的实时性重点讨论了一些关键技术,如模型的创建、LOD技术的实现以及BSP动态碰撞检测算法等,最后介绍了一种动态物体模拟的方法,结果表明该方法不仅使系统的场景更加真实、生动,而且也能使系统高效地实现,很好地满足了虚拟场景漫游系统的实时性要求。
The paper regarded the Virtual Reality as a kind of medium,it introduced the architecture and the implementation process of the virtual scene walkthrough system based on Vega Prime and Creator,and mainly discussed some key technologies around the virtual scene＇s realism and the system＇s realtime,such as the building of the model,the implementation of the Level of Detail,and the algorithm of the BSP dynamic collision detection,etc.At last the passage introduced one way to imitate dynamic objects,and the result showed that it not only made the scene more real and lively,but also was efficient to implement the system,and satisfied the reahime requirement quiet well.
