摘要
目前复杂场景的虚拟漫游一直是虚拟现实和图形学领域一个非常重要的课题,它在城市规划、文化传播、旅游等领域有着极为广泛的应用前景。介绍了怎样把一个实体的大学场景虚拟到计算机上,怎样用MultiGen建模并且在Vega上实现对整个场景的实时漫游。与原有VRML语言所实现的虚拟场景相比较,新系统使得虚拟漫游更加灵活方便且速度显著提高。讨论了几种格式转换中的若干技术问题,以及图片格式的转换和建模的技巧等问题。
At present, virtual roam of complex environments has been an important subject in virtual reality and computer graphics. The technique may be widely applied in many areas such as city planning, culture heritage reservation and tourist induslry. This text tells how to realize virtual campus in computers, how to use MultiGen to model, realizing the whole scene roamed in real time by Vega. Compared with original VRML language, new system is flexible and convenient, and the speed is remarkablely increased. This text discusses certain questions of several conversions of form, picture conversion of form and modeling skills.
