| Abstract: | This paper studied on 3D modeling and rendering of Mars topography based on OSG(OpenSceneGraph),which is an open-source three dimension render engine.Applying the tool of VPB(VirtualPlanetBuilder),it generated PagedLOD database of the whole Mars.The 3D visualization of Mars topography data was achieved by simulation platform based on OSG.The experiments show that this method could process the massive terrain data,and complete the 3D reconstruction of mars topography. |
