Research on realization and optimization technology of 3D roaming function of CIM platform

针对CIM的应用方向和漫游飞行的特点,提出CIM平台漫游功能的优化内容,并由此探讨了该功能实现的关键技术和方法。依托沣西新城的信息模型数据,该文使用CesiumJs引擎快速搭建了CIM城市三维场景,根据CIM场景特点提出更为便捷有效的漫游路径设置方式,使用速度、视口、重力等多种控制方式优化漫游的效果,结合碰撞检测算法,实现漫游的路线纠正功能,通过场景和多种功能配置实现漫游的多模式选择功能。在此基础上,以沣西新城为案例,实现并优化了CIM平台的漫游功能。

According to the application direction of CIM and the characteristics of roaming flight,the optimization content of the roaming function of the CIM platform is proposed,and the key technologies and methods for realizing this function are discussed.Relying on the information model data of Fengxi New City,this paper uses the CesiumJs engine to quickly build a CIM city 3D scene,and proposes a more convenient and effective way to set the roaming path according to the characteristics of the CIM scene,using speed,viewport,gravity and other control methods to optimize roaming Combined with the collision detection algorithm,it realizes the route correction function of roaming,and realizes the multi-mode selection function of roaming through scenes and various function configurations.On this basis,taking Fengxi New City as an example,the roaming function of the CIM platform is realized and optimized.
