Research and Implementation on Visual Analysis of Geological Volume

In engineering applications, the visualization of geological data can help scientists to fully understand spatial distribution of geological information, so that the geological structure analysis will be more intuitive and accurate, which providing an intuitive analysis method for quantitative geological structure research. But at present, in the visualization of geological formation, technologist are accustomed to a single three-dimensional visualization or two-dimensional visualization, without combining them together. This paper studies and implements the key technologies of interaction between two dimensional visualization and three dimensional visualization of geological volume data, algorithms of geological model ´ s cutting and the visualization of bathymetric map. Those technologies provide practicable solutions for full-scale visualization of geological data, and have already been used in the research project of Southern China Geological Form Display.
