Lightweight display of bridge model based on WebGL Technology

Abstract

For the inconvenience of BIM model display, remote browsing and remote interaction of bridge engineering, this paper achieves lightweight display, information browsing and user interaction of the BIM model Web page of Shichuan River Bridge based on BIMFACE secondary development platform. The lightweight display of bridge BIM model is realized by creating three-dimensional model, model format conversion, loading display model, calling function to achieve interaction function, etc. The result shows that this method can well realize lightweight display and interactive function of three-dimensional model Web page. Model lightweight display improves BIM model utilization efficiency and facilitates project management by project participants. In addition, it can be further developed for collaborative management and virtual reality of bridge projects.
