Based on research of large-scale terrain visualization methods, we improve the planar Geometry Clipmaps method by making use of GPU Vertex Processor to projection transform planar terrain into spherical terrain, spherical view culling and spherical viewpoint controlling . We collected and deal with the lunar image and DEM to render the lunar 3D map. The results show that the rendering algorithm’ efficiency is independent on datum but there is distort problem in Lunar Pole.
