摘　　要：提出了一种基于分形的关键帧算法,算法对初始关键帧和终止关键帧之间的压缩映射的对应准则和概率的对应准则各给出了一种较好的解决方法.实验结果表明,算法产生的动画过渡平滑,节奏自然,画面流畅,本文算法的主要特征是它能处理传统的关键帧算法所不能处理的分形物体,在实际应用中,该算法能够在提高制作效率和中间帧质量的同时大大减少动画制作的成本.A fractal-based algorithm of generating in-betweens is put forward in this paper. A relatively good solution to the corresponding principles of contractive mappings and the probability between the start key frame and the end key frame is presented. The experimental results demonstrate that the animation generated according to this algorithm is smooth, natural, and fluent. The main feature of the algorithm is that it can deal with a fractal object whereas the conyentional algorithm cannot. In application, the algorithm can improve the efficiency of animation production and simultaneously greatly reduce the cost.
