校园虚拟现实三维场景建模技术及实现方法研究

虚拟校园是基于虚拟现实技术、地理信息技术将校园地理信息和其他校园信息结合,以三维可视化和虚拟现实场景界面呈现的信息系统,是数字校园工程的重要组成部分。本文主要介绍了建立虚拟校园的主要基础——虚拟校园场景的三维建模技术。讨论了从地形、地貌建模,单体地物建模和建模单元集成的整体流程,并以本校为例给出具体的实现方法。

The Study of Building Virtual Reality Campus with Three Dimensional Scene and Modeling Technology

The virtual campus is an information management system based on a digital data of integrated campus information including geography and other information.By combining virtual reality technology with digital geography information,it could be showed in a three dimensional visualization scene to reflect reality scene in campus.It is a vital component of digital campus project.This article focuses on three dimensional modeling technologies,which are the key elements in building virtual campus and the foundation of digital campus project.It discusses the terrain,the landform modeling,monomial modeling and the modeling unit integration of overall flow,and gives the concrete realization method in the example of virtual campus building at Chonqqing Normal University.
