摘要:BIM服务器为BIM对建设全生命周期的支持提供了解决方案。目前BIM服务器主要为C/S架构，但B/S架构的优势也渐渐凸显。HTML5标准的发布带来了支持浏览器硬件图形加速的WebGL技术，更带来了一系列划时代的Web技术。从而为实现B/S架构下的BIM信息管理与模型三维浏览奠定了基础。本文分析了BIM的模型信息范围与表达形式，研究了基于WebGL框架Three.js的BIM模型显示技术以及面向Web的BIM信息管理技术，开发了BIM模型三维浏览与信息显管理系统。应用表明，系统的图形平台性能稳定，渲染效果较好，能够支持较大的BIM模型。同时，系统为Web客户端提供了丰富的功能支持，更体现出良好的交互特性，因而具有较大的应用价值。
Abstract: BIM Server provides a solution for BIM to support construction life cycle. Currently, the structure of BIM Server is C/S, but gradually B/S also shows its advantages. The release of the HTML5 standard brings the WebGL technology which supports hardware graphics acceleration in browser and is one of a series of revolutionary Web technologies. Thereby the foundation is laid for achieving Web-oriented BIM information management and 3D display of BIM model. In this paper, the model information scope and its expression of Web-oriented BIM is analyzed, and the corresponding information management technology and the BIM model display based on the Three.js, which is a WebGL framework, are studied. Then, a WebGL-based platform for 3D display and information management of BIM is also developed. Application shows that the graphics platform of the platform performs stable with nice rendering for large BIM. Meanwhile the platform provides rich feature supports for Web client by favorable interactive functions, showing a great application value.
