中文摘要: 采用虚拟现实技术设计了动力馆的漫游系统,通过CAD软件和3D Max进行动力馆建筑结构和动力设备的建模,并通过修改VRML代码,控制系统的漫游和设备的运行仿真.为了增加虚拟漫游系统的真实感,采用基于视线的向前线段探测的碰撞检测方法,以保证虚拟物体给人的感觉是真实的"物理存在".为了提高浏览速度,采取设定可视距离、层次细节模型以及分割场景的方法,进行了系统优化.最后,通过网络将漫游系统展示出来.
Abstract:The paper designs the walkthrough system of the power engineering laboratory based on the virtual reality technology.CAD software and 3D Max are applied to set up the models of the laboratory structure and power equipment,and the VRML codes to control the walkthrough process of the building and the simulation of the equipment operation.Meanwhile,forward linear detection based on sight light,a collision detecting method,is adopted to enhance the system immersion and ensure that the virtual object has the effect of a real "physical existence".The paper optimizes the system to accelerate the browsing rate through setting sight limit,level of detail and splitting scenes.Finally,the walkthrough system is exhibited in the Internet.
keywords: virtual reality walkthrough system model simulation
