This paper analyzes the basic linear generation algorithm, circle generation and filling algorithm, Bezier curve generation algorithm in the graphics, and combined with the VC to achieve the algorithm. The theoretical and experimental comparison of 4 basic algorithms for linear generation. This paper discusses 5 methods of circular regions filling,the midpoint circle algorithm, Bresenham algorithm, circle equation, seed filling algorithm and symmetry points algorithm,and then the efficiency of these 5 kinds of Circle filling algorithm is compared by experiments. According to discuss and analyze the different implementation ways.It has a certain guiding significance.It is good for students to master relevant knowledge and improve their professional skills.
