Research on 3 Dimensional Visualization of Geological Environment Information

Traditional 2 dimensional visualization method of geological data is carried out in 3 dimensional by OpenGL. This include process and visualize of large scale data of digital elevation model height data, remote sensing texture data, geological environment information data of point, line and polygon types together with geological body data. The result proves that 2 dimensional visualization methods of geological data can be replaced by 3 dimensional with better intuitive and effective, which is also a developing trend in the future.
