摘要
虚拟现实是现代仿真技术的一个重要发展方向,在城市规划、环境保护、战场模拟、作战训练中可以很好地辅助决策。构造可漫游的虚拟场景是虚拟现实中最基本的、必不可少的一个环节。论文在简单介绍了构造虚拟场景的一般性步骤后,重点讨论了地形、天空体、地物地貌、自然现象等关键技术及漫游控制与漫游辅助工具的实现等。实践证明,所实现的虚拟场景在实时性与真实感方面均取得了不错的效果。
Virtual reality is an important developing direction of simulation technology, and it can help to make decisions at city planning, environmental protection, war field simulation, campaign training, and so on. A virtual scene roamed randomly is a basic and necessary part in virtual reality. The run-of-mill approach of constructing a virtual scene was introduced and the pivotal technologies of terrain, sky, physiognomy, natural phenomena etc were discussed, and the realizations of roaming control and roaming assistant tools were given. The simulating results show that the virtual scene acquires satisfied effects in real-time and third dimension.
