Three-dimensional Geological Modeling And Imitating

Three-dimensional Geological Modeling and imitating shows us the way of using computer to construct the system of three-dimensional Geological Modeling together with people and emphasizes the important role of the interaction between computer and people in the Modeling. Based on the orient object and the theory of component, this thesis completes demand analysis. The system puts forward a framework by means of the componential structure of orient object and the idea of realizing the data communication among the individual components of the system through software bus. On the basis of demand analysis, this thesis finishes the design of the system and realizes some key functions, including industrial section modeling, the drawing and the mutual modifying of the drill histogram, the formation and the perfection of the projection section, the construction of stratum modeling, and the realization of the mechanism of data communication administration.This thesis gives a brief account of the basic theories of software engineering and computer graphics, of the data structure of individual component modeling, of the design of the software structure and of the method of realizing software. Meanwhile, this thesis put more emphasis on the exploration of the arithmetic of the Delaunay triangle network, NURBS curve integration, the filling-in arithmetic of triple-tree, and the arithmetic based on the scan-line arithmetic and the filling-in of complex section.The thesis offers the idea of applying the techniques of data-administration, computer transaction, computer graphic and the interaction between computer and people in the emulational research of the construction of three-dimensional Geological Modeling, which also succeeds in realizing the protracting of the administration of geological data, the layout of industrial section, complex section chart, complicated isoline chart and the three-dimensional Geological Modeling chart, and in providing valuable references for geological research and technological support for three-dimensional and complex Geological research. This software system offers correlative experience for the development of three-dimensional Geological Modeling of the same type.
