The Simulation Research Of Computer Graphics Algorithm Visualization

In recent years, visualization technology rapid development, from 1986 to now, it gets extensive attention in computer graphics field. A lot of research scientists start to discuss this problem, and get great progress. In a foreign country, visualization technology has applicated in the lab, each system and class teaching demonstration as a means. At home, although related scientific research achievements are few, but visualization technology has caused much attention of the research scientists, it would be surely present a broad application fields.Computer graphics algorithm visualization technology can be divided into two categories. One is 2d graphics, another is 3d graphics base on space. Base on thorough study of visualization technology, combined with the characteristics of computer graphics algorithm, study separately of 2d graphics and 3d graphics, then proposed a new algorithm and produced results correspond. This paper's main work include:(1) Proposed coordinates virtual transformation algorithm. Achieved a visual simulation system CAI of Bezier curve. Implementation of the system, discard the method of calculate the best approximation"pixel"position to display graphic in original system, but with the establishment of a observed coordinate system, control point coordinates transformed to the observe coordinate system, it is controlled the graphics generation to achieve the final result. The result shows that this method can actualize the generation process of Bezier curve, it has little calculation, low complexity, generate fast and good fidelity.(2) This paper proposed a method of split triangle, then achieved a visual simulation system CAI of 3D sphere. Implementation of the system, discard the method of calculate the best approximation"pixel"position to display graphic in original system, we use triangles instead of"pixels", segmentation of triangles in order to achieve the ultimate effect .The result shows that this method can actualize the generation process of 3D-graphic, it is very realistic and fast.
