Applied Study Of Geological Visualization System In Scientific Computing --Applied Study And Design Of The Geological Visualization System Based On Component Object Mode

As the information age has come, the computer graph technology has also come into a new develop field. The Visualization in Scientific Computing has been advanced. The needs about the graph and image have increased continually. It is inevitable that the numeral image process technolnogy are infiltrating other siences and are being used by them. And, it's important to realize visualization in the geological field.This article mainly introduces the methods of how to realize the geological scientific information visualizaion in the geology and achieved managing geological information scientifically and visualizational computer analyzing. It also gives thorough discuss about arithmetic methods about the geological visualization.In the meantime, as the Oriented Object Technology has come in the 1970's, it has been applied widely in the software designing. After the 1980's, it's been the trend of the programming. In the system designing, the software engineers advanced new oriented object method: the Unified Modeling Language. In the program structure, the Component Object Model and the Distributed Component Object Model are one of the most important developments in the Oriented Object technology.This article introduces at length the concepts and theories of COM and the Oriented Object software development process. Combined with the real needs of constituting geological information visualization application, it takes the Geological 3D visualization System , which was based on component object model, as an example and gives thorough discuss about not only the process of how to use different COM application technologies, such as ActiveX, ATL and so on, to design the system, but also how to realize the 3D model cutting by OpenGL, a 3D graphics library. The idea of this solution is consistent with that geological 3D visualization system.. It was proved by lots of experiments and applications in this project that geologic 3D Visualization in Scientific Computing based on COM is feasible and promising.
