The Research And Implementation On OpenGL Based Scientific Visualization Arithmetic

With the help of the technology of computer graphics and computer image processing, both the intermediate data and the final result of scientific calculation can be shown directly and handled mutually. Therefore, in this way ,some abstract rules and theories would be much easier to understand,a lot of lengthy and uninteresting data become vivid and attractive. At the same time,it will enrich visual technology in computer field, and promote the development of relevant subject.This thesis made researches on scientific visualization arithmetic based on OpenGL, and built a good foundation for relative work in many fields . Firstly, it introduced the background of the development of scientific visualization both domestic and abroad ,including the state of the development and the significance of the study as well as the basic theory of three-dimensional visualization.Secondly, it expatiated on the OpenGL programming technology and environment ,and created the 3D-graphics classes in C++ programming language, thus made it more convenient to use OpenGL under a MFC programming environment .Then, the software of scientific visualization was developed ,mainly research on the development of the algorithm of the visual component , i.e. the algorithm of the contour graphic and pseudo-color. Besides ,the software development also was given.
