基于WebGL的BIM模型可视化研究

针对水利工程建筑信息模型(BIM)展示需安装专业软件及展示不便、不能远程浏览和远程交互不便等问题,采用基于WebGL技术的Three.js框架,通过坝体三维模型的建立与导入、浏览器中坝体模型的重构、模型环境的渲染等技术手段,实现了大坝三维模型在客户端浏览器Web方式可视化显示、三维漫游及远程实时浏览与交互,避免了模型展示需安装专业软件的繁琐过程,增强了展示效果,提升了用户体验,并可进一步应用于水利信息化可视平台的开发。

Research on Visualization of BIM Model Based on WebGL

Aiming at the problems of BIM model displaying in hydraulic engineering, such as installation of professional software, inconvenience of display, inconvenience of remote browsing and remote interaction, the three.js framework based on WebGL technology is used to implement building and importing three-dimensional dam model, rebuilding dam model in browser, and rendering model environment, etc. The visualization display, three-dimensional roaming and remote real-time browsing and interaction of the three-dimensional dam model are realized in client web browser, which avoids the tedious process of installing professional software for model display, enhances the display effect and the user experience. It can be further applied to the development and application of visual information platform for water resources.
