3D visualization and interaction technologies applied in the modeling of geological bodies

Visualization is recognized as a fundamental element in scientific and engineering fields, and has being found wide applications in many areas such as medical care, meteorology, biology and geology. The dataflow model of visualization process is described, and a visualization technique is introduced to construct the complex geological bodies. The reconstruction process of geological bodies is greatly speeded up by the suggested algorithm. The problems of 3D human-computer interaction used in the visualization are investigated, and the solutions are provided. The implementation of 3D visualization and interaction increases the usability and agility of the system developed by the authors, which is testified by real data obtained from two mines in China.
