Application research of web-based BIM model lightweight platform

After the 14th Five-Year Plan, with the overall planning of the country, provinces and cities have introduced their own plans and goals, and the ministries and departments of the construction industry have also landed relevant documents and policies to promote the development of digital city integration, gradually established the requirements of digital city construction for BIM technology. At present, in the construction industry, there is an increasing demand for lightweight BIM models, but the efficiency of rendering models on the web side is still to be improved. To address this pain point, this paper designs a lightweight platform for fast loading of BIM models on the Web side based on WebGL 3D engine and optimized processing through format conversion, which reduces the volume of models while retaining model information, improves the loading performance of models on the Web side, and provides a new solution for enterprises to build a lightweight platform for BIM.
