三维虚拟建筑空间体验系统设计

Design of 3D virtual building space experience system

基于VRML的三维虚拟建筑空间体验系统仅能实现静态体验,无法进行动态交互体验,用户体验性能差。因此设计新的三维虚拟建筑空间体验系统,采用B/S结构将三维虚拟建筑空间体验系统分为客户层、逻辑层、数据层,在二维地图的基础上,运用3ds MAX三维虚拟建模程序以及Photoshop等软件构造建筑空间三维模型,通过X3D以及三维建模程序进行三维虚拟建筑空间模型中的地图、建筑、交通、植被元素的建模。系统通过Dreamweaver软件的框架网页工具实现静态三维虚拟建筑空间体验,将三维虚拟建筑空间模型导入仿真软件中,对模型进行材质、灯光设置等操作后,通过插件将设置好的模型导入到VR-Platform软件中设置模型运行窗口,实现交互式三维虚拟建筑空间体验。实验结果表明,所设计的三维虚拟建筑空间体验系统具有较强的真实感和交互性,具有较高的用户体验性能。

Since the 3D virtual building space experience system based on the VRML can only realize static experience without dynamic interaction experience involved,and has poor user experience performance,a new 3D virtual building space experience system is designed.The B/S structure is used to divide the 3D virtual building space experience system into the custom-er layer,logic layer and data layer.The 3ds MAX 3D virtual modeling program and Photoshop software are used to construct the 3D model of building space on the basis of the 2D map.The X3D and 3D modeling program are used to conduct the modeling for elements of map,building,traffic and vegetation in the 3D virtual building space model.In the system,the framework and web tools of the Dreamweaver software are used to realize the static 3D virtual building space experience.The 3D virtual build-ing space model is imported into the simulation software.After operations such as material and light settings for the model,the set model is imported into the VR-Platform software to set the model running window by using the plug-in,so as to realize the in-teractive 3D virtual building space experience.The experimental results show that the designed 3D virtual building space experi-ence system has strong sense of reality and interaction performance,and high user experience performance.
