摘　　要：在一些应用场景中,需同时使用GIS三维引擎与游戏引擎,本文提出了一种跨平台同步匹配定位方法。通过调节场景的同步表达,实现根据不同视觉尺度的三维可视化需求,灵活配置适宜的三维引擎,并解决不同三维引擎下场景切换过程中存在的定位不精准、体验不连贯等问题。本文方法成功应用于实际案例中,为GIS三维引擎与游戏引擎的有效融合、优势互补提供了便捷的解决方案。In some application scenarios,there is a need for concurrent utilization of both GIS 3D engines and gaming engines.This paper proposes a cross-platform synchronous matching positioning algorithm.The aim is to achieve flexible configuration of suitable 3D engines according to different visual scale 3D visualization requirements,through adjusting the synchronous expression of the scene.This also resolves issues such as inaccurate positioning and discontinuous experience during scene switching under different 3D engines.This algorithm has been successfully applied in practical cases,providing a convenient solution for the effective integration and complementary advantages of GIS 3D engines and game engines.
