基于UDK的数字校园虚拟现实引擎关键技术的研究

虚拟数字化校园漫游系统是数字化校园建设计划的核心平台。本文首先对目前主流的虚拟可视化开发工具作了介绍，并结合当今最流行的游戏引擎UDK（Unreal Development Kit）和三维设计软件3ds Max的虚拟现实关键技术问题进行了研究，以无锡城市职业技术学院校区为原型，设计并实现了将虚拟现实引擎作为三维动态交互立体数字校园开发平台的核心构件，着重对引擎实现过程中的3ds模型导入进行了解析，包含了材质编辑技术、物理碰撞技术及碰撞检测技术等关键技术。结果表明，上述技术的通用性在虚拟现实引擎中可见一斑，极大地提高了引擎的实用性和执行效率。

Research on the Key Technology of Digital Campus Virtual Reality Engine Based on UDK

Virtual campus roaming system is the core platform of digital campus construction.This paper introduced the main tool of virtual visualization development,combined with today＆#39;s most popular game engine UDK （Unreal Development Kit） key technology of virtual reality and 3D design software 3ds Max was studied,taking the Wuxi City College of Vocational technology campus as the prototype,design and implementation of virtual reality engine as the core component of 3D dynamic interactive three-dimensional digital campus development platform,the 3DS model into the engine in the process of realization were analyzed,material editing techniques,collision physics technology and collision detection technology. The results show that,the remarkable versatility technology in virtual reality engine,greatly improves the practicability and efifciency of the engine.
