一种用于虚拟校园漫游的三维引擎的研究

摘要

After analyzing the 3D engine technology named OSG, it presents and realizes the 3D engine for campus ramble. Some classes and interfaces of OSG are used to accomplish the interaction control and rendering the scene of virtual campus in the sys-tem. In addition, the audio introduce function can enrich the audio-visual sensation of users. The practice has proved that the en-gine has portability and universality and it supplies support for the transfer of campus ramble technology to virtual campus system and the virtual learning platform.%在对三维引擎技术OSG进行分析和研究的基础上，提出并实现了一种用于虚拟校园漫游的三维引擎系统，该系统使用OSG所提供的类和接口，实现了虚拟校园场景的渲染以及漫游的交互控制功能，同时在引擎中添加了语音介绍功能，丰富了浏览者的视听感受。实践证明，该引擎具有良好的移植性与通用性，为虚拟校园漫游技术向虚拟校园系统和虚拟学习平台方面的迁移提供了支持。
