Parameterization of Complex Pipeline Meshes and Its Large-scale Online Visualization

doi:10.16182/j.issn1004731x.joss.19-VR0468

Abstract

Abstract: With the application of WebBIM technology in the field of large-scale building models, the complexity of models and the number of components are growing geometrically. The complex pipeline grid model is a key issue of affecting the lightweight of the BIM models and online rendering rate. In order to reduce the data volume and complexity of the complex pipeline meshes, a lightweight parameterization algorithm for the general cylindrical pipeline meshes, the curved pipeline meshes and also the hollow pipeline meshes is proposed. Redrawing the parameterized pipeline model and some visual optimization methods such as LOD technology being used reduce the rendering burden in the WebBIM scene. The application in the large-scale scene shows its significance in engineering practice.

Key words: pipeline parameterization, complex grid, lightweight, WebBIM, large-scale online visualization
