基于WebGL的Revit三维建筑模型重建

Revit three-dimensional building model reconstruction based on WebGL

结合WebGL和BIM技术,在浏览器端重建Revit三维建筑模型可以使用户方便地在浏览器上查看三维模型.针对Revit三维建筑模型全信息重建,通过Revit API将Revit Architecture三维建筑模型文件转换成包含几何信息和属性信息的JSON格式文件,并使用WebGL解析JSON文件达到在PC浏览器端和移动浏览器端实现Revit Architecture三维模型重建的目的.同时提出一种在JSON文件中模型对象和模型属性信息关联的方法,并提出了一种针对大场景,基于Revit"族"对象的LOD优化算法.

The Revit 3D building model reconstructed in the browser combining WebGL and BIM technology can help user browsing 3D model in the browser conveniently. This article aims to reconstruct Revit 3D building model with full information. Through Revit API, the file of Revit 3D architecture model can be converted to JSON format file with geometric information and property Information. Then the WebGL is used to parse JSON file in order to achieve Revit Architecture 3D model reconstruction in the PC browser and mobile browser. In the meantime, a associated method between model object in JSON file and attribute information associated with the model is proposed. The LOD optimization algorithm based on Revit family in big scene is put forward.
