【摘要】：針對(duì)通用三維GIS平臺(tái)開發(fā)提供了一種基于開源跨平臺(tái)三維GIS渲染引擎osgEarth的技術(shù)方案,并對(duì)其中大地形三維模型實(shí)時(shí)生成和加載、LOD分頁(yè)數(shù)據(jù)等關(guān)鍵技術(shù)展開了研究。分析了osgEarth的特點(diǎn)和數(shù)據(jù)加載流程,結(jié)合實(shí)際項(xiàng)目應(yīng)用介紹了平臺(tái)方案的實(shí)現(xiàn)及效果,對(duì)于工程實(shí)踐有一定的指導(dǎo)意義。
[Abstract]:This paper presents a technical scheme based on open source cross-platform 3D GIS rendering engine osgEarth for the development of general 3D GIS platform. The key technologies such as real-time generation and loading of large terrain 3D model and LOD pagination data are studied. The characteristics and data loading flow of osgEarth are analyzed, and the implementation and effect of the platform scheme are introduced in combination with the actual project application, which has certain guiding significance for engineering practice.
