| Abstract |
With the in-depth application of BIM technology in urban construction, how to efficiently load and parse BIM models with tens of millions of triangular patches, and how to combine BIM with GIS system to support the management of smart city are the two key technologies that are urgently needed to break through. This paper optimizes the lightweight of BIM data and WebBIM visualization, using Cesium as the engine of WebGIS system to perform geographic information rendering, while Three.js engine is used to render WebBIM models. The successful combination of WebGIS and WebBIM gives support to many novel solutions for smart city visualization management such as BIM cutting and view point switching. It enables users to smoothly view and edit large-scale BIM models in web browsers without any third-party plugins and establish a multi-party collaboration platform with WebGIS as the core. |
