| Abstract: | 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. |
