3D-reconstruction based on geology landscape of VR-GIS

The three dimensional landscape reconstruction is one of the important aspects in the research of Virtual Reality Geographic Information System(VR-GIS). In order to explore the processing of Gigabytes geology data, the 3D-landscape reconstruction algorithm based on volumetric data is presented. And the quick reconstruction problem of large scope of geology landscape under the microcomputer environment is resolved. At last, the 3D geology landscape reconstruction technology is analyzed and discussed in combination with the practical data. The corresponding algorithm, technical flow chart and legend are presented in this paper.
