基于BIM和WebGL技术的异步场景漫游方法
Asynchronous Scene Roaming Method based on BIM and WebGL Technology
摘要
Abstract
With the rapid development of page rendering technology,cloud BIM applications are emerging,and due to the limitation of browser processing power and computing resources,it poses new challenges for the smooth browsing and operation of large-scale BIM models.In order to solve the problem of smooth browsing and operation of large-scale BIM models,a method of scene path roaming in the asynchronous loading mode of BIM models is proposed through WebGL technology,which realized the asynchronous loading of 3D light-weight BIM models on the web side and improved the frame rate of the model.At the same time,through the spline algorithm,the roa-ming path is specified by key points,which improves the interactivity of creating the roaming path.Finally,algorithms such as dynamic culling and occlusion elimination of viewpoints are used to ensure the smoothness of rendering roaming animations.The verification results show that the proposed method can effectively improve the fluency and stability of the path roaming of large-scale BIM models.关键词
