| Abstract:Three-dimensional modeling for geology is one of the focused issues in geoscience community around the world. It abstracts geological re鄄
sults into geological models and realizes visualization analysis and management on computer. This study illuminates the principle of the modeling method,
data processing and visualization analysis, and integrates practice experiences of three-dimensional modeling in geology. Then some of the key technical
issues involved in three-dimensional geological visualization, such as data fusion, mesh generation, and virtual reality are discussed, and some specific
examples are presented. This work demonstrates that three-dimensional geological modeling can not only express more complex geological information effi鄄
ciently, but also be applied to engineering practice. Besides, this paper discusses how to use the routine software AUTOCAD to transform cross sections
into geological maps in accordance with regularities and apply this technology to production practice. |
