摘要:

针对网络环境下大规模虚拟场景的实时生成中所面临的速度问题,通过对VRML(Virtual Reality Modeling Language)工作原理和优化技术的分析,提出一种基于网格化管理的大规模虚拟场景的实时载入方法,实现了虚拟校园场景的生成系统。通过有选择地下载和渲染小部分场景,可提高生成速度,便于大规模场景的实时浏览。

关键词: 虚拟现实, 虚拟场景, 实时下载

Abstract:

By analying VRML(Virtual Reality Modeling Language) principle and its optimization technology, a realtime downloading and loading method based on net management is presented to solve speed problem facing in real-time generation of a large scale virtual scene in a networked environment. Through selecting and rendering some small parts of scene, the generation speed is improved and it is helpful to explore a large scale virtual scene in real-time, a system for rendering virtual campus scene based on the above method was developed.

Key words: virtual reality, virtual scene, real-time loading
