摘要
针对目前广泛使用的地下管网系统在三维描述方面的欠缺,本文利用虚拟现实技术和VRML语言,构建了基于VRML的三维地下管网信息系统。这一系统的实现,用户可通过网络异地浏览地下管网的三维虚拟模型和查询相关数据信息,大大提高了工作效率和城市数字化管理水平。
The under-ground piping-net information system used currently is short of describing the piping in three dimensions. Aiming at this point, the 3D under-ground piping-net information system is achieved with the help of virtual reality technology and VRML language in this paper. With the system, users can browse the 3D under-ground piping-net virtual model and search interrelated datum, which raises the efficiency and standard of citiy digitizing management.
