摘　　要：现有施工工艺三维可视化方法存在难更新、软件环境限制或非动态等问题。为解决上述问题,结合Cesium提出面向Web的施工工艺三维动态可视化方法,包括相关数据模型与动画定义方式,以动画帧切分和帧集成为核心的三维动画快速生成方法,经效率测试显示,帧切分与帧集成算法性能可满足一般施工工艺动画需求。同时,应用上述方法实现案例工艺Web端展示与工艺步骤动画的在线编辑、播放与动态更新,验证实际工程应用的可行性。The existing 3D visualization approaches for construction processes have difficulty updating,limited software environment,or undynamic results.For solving the above problems,a web-oriented 3D dynamic visualization method of construction processes is proposed based on Cesium,including relative data models and animation definition,and a rapid 3D animation generation method based on frame segmentation and integration approaches.An efficiency test proves that the performance of frame segmentation and integration algorithms can meet the needs of general animation of construction processes.Besides,the above method is applied to show a case construction process on the web and to support online editing,playing,and updating of the process step animation,which verifies the feasibility of using the method in actual projects.
