Three-dimensional geological data visualization, which application classification includes expression visualization, analysis visualization, procedure visualization, design visualization and decision visualization, has a prominent property of spatial decision support. The problem whether the geological visualization software can implement these five kinds of visualization or not constitutes the touchstone. The expression of the complex geological structure and the rapid dynamic modeling method and technology will be the research focus for some time in the future. The introduction of knowledge driven thinking and ontology may be an effective and adequate solution of these problems.
