As the remarkable progress and the widespread application of computer graphics, it has become a bridge between the computer science and other application disciplines, and it is one of the required courses of many undergraduate professionals. This paper implements a raster graphics teaching demonstration system, which under the Windows XP platform and Visual C + + 6.0. This paper analyzes the system in detail, and determines the appropriate structure and main functions, as well as the technology adopted in actual development. The teaching demonstration system can show the visual working process of various algorithms, such as the line scan conversion algorithm, the arc scan conversion algorithms, the polygon scan conversion algorithms, the area fill algorithms, the line and polygon reduction algorithm and curve, surface generation algorithm. The system operation is simple and can display the raster process in the simulate raster area in accordance with the principles of these algorithms, which not only can more vivid display the working process of various algorithms in teaching, but also could facilitate students to better understand the basic pattern generation algorithm in the learning process. Meanwhile, this paper describes the whole process of system development and design. It does a detail expression of the algorithm principle and tests the function of the system. The system implements most of the basic pattern generation algorithms, and
