基于Cesium的隧道变形可视化研究
Research on visualization of tunnel deformation based on Cesium
摘要
Abstract
In order to study the 3D visualization and displacement display of tunnel models,the 3D Earth platform Cesium was used to construct overall and detail views for visualization analysis of tunnel overall and segment models.Using BIM modeling software Autodesk Revit to create a tunnel model,the model was exported and converted to file format.The Draco compression algorithm in BIM lightweight technology was used to optimize the vertices and file size of the model.The lightweight model was imported into the Cesium platform,and the position and orientation of the model were adjusted.The continuous displacement of the tunnel model was achieved through two methods to show the deformation process of the tunnel.Studies resumes show that the Draco algorithm is very effective for the lightweight of the BIM models,reducing model file size by more than ten times after application,and ensuring high fidelity of model data.The three-dimensional visualization engine Cesium can change the physical properties of tunnel models through the relevant attributes and functions,thus simulating the effect of tunnel deformation,and facilitating the functional expansion of tunnel models based on visualization analysis.关键词
