摘要
BIM (Building Information Model)模型是智慧城市建设重要的数据基础,同时随着计算机图形学和WebGL (Web Graphics Library)技术的发展,在网络环境下实现BIM数据可视化与查询分析,能够实现BIM信息的共享同时为工程设计提供重要的技术支持。BIM数据具有丰富的几何信息和语义信息,如何与地理场景融合展示,是需要解决的难题。基于此,本文提出了基于WebGL的BIM数据网络可视化方法,通过数据解析、格式转换、几何重构和三维表达,实现了BIM数据在网络环境中的加载与可视化,相关成果可以为BIM和三维GIS集成及相关工程实践提供借鉴。
The BIM (Building Information Model) is an important data foundation for the construction of smart cities. With the development of computer graphics and WebGL (Web Graphics Library) technology, BIM data visualization and query analysis in the network environment can be realized. And also the sharing of BIM information can provide important technical support for engineering design. BIM data has rich geometric and semantic information, and how to fusion with the geographical scene is a tough problem. Based on this, this paper proposes a method of 3D visualization of BIM in the network environment based on WebGL, which realized the loading and visualization of BIM data through data analysis, format conversion, geometric reconstruction and 3D expression. The related results can provide support for the integration of BIM, 3D GIS and other engineering practices.
