基于OSGEarth的城市三维场景构建

基于OSGEarth开源工程,采用LOD与分页、动态调度等技术,研究了三维地形、影像、地物组织、调度及融合方式;并以泰州市为例,实现了基于OSGEarth城市三维场景的构建,达到良好的效果,为以后的中小城市"数字城市"建设提供了空间框架。

Construction of Urban 3D Scene Based on OSGEarth

In this paper,on a basis of the OSGEarth open-source project,we researched on 3D terrain,images,objects organization,scheduling and fusion techniques,carried out by the use of the technologies of LOD(Levels of detail),paging and dynamic scheduling and so forth.Taking Taizhou for example,the construction of urban 3D scene with good results was acquired by using OSGEarth,which provided a spatial frame for future construction of small and mediumsized digital cities.
