基于虚拟现实的数字化校园漫游系统设计

摘要

As a part of the construction of digital city, virtual touring system of digital campus is the core platform of digital campus constructional plan. On the Jinjiling campus of Guilin university of electronic technology as the prototype, using 3DS MAX , a 3D stimulation model of virtual campus was built up. Adopting both development platform of VR-Platform and SQL server backend database connections, combining virtual building and photography imaging.a 3D virtual campus touring system was designed and implemented, some functions were implemented including self-independent roaming, path automatic roaming, bird eye view and building inquires. By improving scenes' optimization technology, the experimental results show that the system operates effectively, stably and fluently in ordinary PC.%作为数字城市建设的一部分,数字化校园虚拟漫游系统是数字化校园建设计划的核心平台.以桂林电子科技大学金鸡岭校区为原型,运用三维仿真技术建立了基于3DS MAX的虚拟校园三维模型.采用VR-Platform开发平台与SQL server后台数据库连接、虚拟建筑与实景拍摄相结合的方法,设计实时三维虚拟校园漫游系统并实现了自主漫游、路径自动漫游、鹰眼鸟瞰和楼宇查询等功能.实验结果表明,使用改进的场景优化技术,提高了其系统运行效率,在普通PC机上实时运行也很稳定、流畅.
