Abstract: The intermediate frame generating technology has become a hot topic in the visual research field of computer animation. This paper, aiming at the shortage of the traditional intermediate frame generating method, proposes an intermediate frame generating method based on the analysis and elaboration of the basic principle of DBBS（Disk and Ball B-Spline curve）models. According to the situations of the difference in the sharpness of the candidate points on the key frames, it presents a pretreatment method which could meet the corresponding conditions to generate the intermediate frames. At last, it shows that the effect of this method is better and faster than that of the traditional method through the experiment.
