Application of Volume Visualization and 3D Interaction Techniques in Geological Bodies Modeling

The theory and methods of volume visualization are discussed. The reconstruction procedure of geological body is greatly speeded up by the suggested algorithm, which is based on the original volume visualization algorithm （Ray-casting） and the features of geological data. The problems of 3D human-computer interaction used in the volume visualization are investigated, and the solutions are provided. The implementation of 3D interaction increases the usability and agility of the system developed by the author, which is testified by real data obtained from an iron mine in China.
