Study on the Method of 3D Geologic Modeling and Visualization

Abstract:

Three-dimensional Geologic body modeling is one of the core problems in geological information system. The current situation of three -dimensional geographic information system (GIS) and method of space modeling were analyzed in geological field, a kind of three-dimensional geological space modeling method-Similar Tri-Prism(STP) was put forwards, STP Combined with the characteristics of Geological body engineering. This method took Similar Tri-Prism body as the basic volume element of three-dimensional geological modeling, and described the data structure of Similar Tri-Prism body by using five basic elements and six groups of topological relationships. It can effectively express all kinds of three -dimensional geological phenomenon, can better combined with traditional multi-layer triangular irregular network (TIN) model, as well as maintain the topological relationship of space entity. An initial prototype has been developed basing on the modeling method in this paper and proved by real drilling data,which is suitable for three -dimensional GIS in geological field.
