虚拟漫游系统的研究

基于软件平台MultiGen Creator和Vega开发的虚拟场景漫游仿真系统．提出了视景节点的软硬件配置要求；论述了基于Creator的实体建模方法、基于Creator建模和Vega软件环境的天空效果生成方法、声音的调用、视景仿真软件的开发过程以及整体系统的实现等关键技术．仿真结果表明，该视景仿真系统逼真地演示出在虚拟场景中漫游的的过程，并且满足系统仿真的实时性要求．

Study Of Virtual Roam System

Base on software platform-multiGen creator and vega,the visual simulation system of virtual roam was developed. The software and hardware requirements of the vision node were proposed. The solution to a series of key techniques was discussed; such as the modeling method based on creator,the effect generation of the sky based on modeling and vega software environment, the transfering of the sound,the development of visual simulation software and the implement of whole system. The simulation results show that this visual simulation system can realistically demonstrate course that produce of the virtual scene roaming,and besides,it satisfies the real time requirement of system simulation.
