文档介绍：摘要
虚拟现实技术是20世纪末发展起来的一个涉及多学科的高新技术。虚拟现实技术可以应用于许多领域,如商业、教育、视景仿真等领域,逐渐成为研究热点。Vega Prime技术则是虚拟现实技术中比较热门的一种。
本文介绍了在MultiGen Creator/Lynx Prime两种软件的结合使用下,通过建立模型、创建三维场景、设定漫游路径的步骤来表现小区中各种景物景观以及住宅的仿真视景,并建立一个漫游系统。
首先需要用Creator软件建立需要呈现的景物模型,本文涉及到的模型有居民楼模型、树木模型、路灯模型、道路模型、河流模型、地形模型等,并对模型进行贴图,使模型看起来逼真;其次就是在整个场景中运用实例化导入等技术,将各个小模型组合导入场景,使之成为一个完整的城市街景小区的场景;然后,将场景导入Lynx Prime软件中形成可视的ACF文件,做出逼真的可视化效果,可以清晰的看到小区中的各个部分景观以及整体景观;最后,为了使观察者能按照一个规定的路径来轻松浏览小区景观,通过编写Visual 2003平台下的C++程序,来实现漫游路径的设定和观察者视角的切换。

Abstract
The virtual realistic technique is a new technique that involves many academicses that deveolps at the end of 20th virtual realistic technique can be applied to many realms, merce, education, see a view to imitate true etc. realm, Be e studying hot Prime technique the then virtual realistic technique is amid more popular kind.
This text introduced at MultiGen Creator/Lynx Prime two kinds of softwares of pass to create pattern and create three-dimensional scene that the pattern, setting travels extensively path to express various scenery view in the living quarter under the wedge bonding use and residence of imitate to really see a view, and create traveling extensively of a city street view living quarter system.
Need to be needed with the Creator software establishment first of present of scenery pattern, this text involves of the pattern have the resident the building pattern, tree pattern, lamp pattern, way pattern, water pattern, and geography pattern...etc., and carry on a picture to the pattern, make pattern look lifelike turn;Secondly be make use of a solid instance to turn in the whole scene the techniques like guide,etc puts together connecting to each small pattern progress and make it es the scene of the city street view living quarter of an integrity; Then, inducts the scene in the Lynx Prime software to form the visible ACF document, makes the lifelike visualization effect;End, for making the observer able to easil
