Abstract

Abstract

In response to the challenge that current hardware performance and network bandwidth are insufficient to support real-time rendering of massive data in 3D scenes, a web-based building information modeling (BIM) scene roaming solution was proposed. Initially, the BIM model was reconstructed, and a top-down hierarchical structure was employed to achieve fine-grained instances of scene components. Subsequently, model compression was completed based on the spatial position of vertices and the similarity calculation between components to shorten the display delay of the scene. Finally, a visual component picking algorithm based on the two-layer architecture of view frustum ball and view frustum was designed to complete scene selection and rendering by off-line component number and reduce hardware load. Five different scale scenarios were selected for validation. The results demonstrate an average compression rate of 45%, which enables smooth 30 frames per second roaming for GB-scale scene in web-based applications.
