摘　　要：随着计算机系统、图形输入、输出设备的发展，计算机图形软件及其生成、控制图形的算法也有了很大发展，计算机图形教学的内容也从各种基本图形的产生、变换、裁剪等，发展到真实感图形生成及动画设计。而交互图形输入作为图形生成及动画设计的基础，直接影响动画设计的效率和效果。该文针对动画设计的一些关键技术，采用无浮点、无除法的整型算法，设计了各种图形的快速输入，探讨了物体离散逐点变化的变型体技术、根据给定参数生成关键帧序列，然后插值中间画的参数动画和动画背景设计等关键技术及其实现方法。With the improvement of computer system and graphic imput and output device, computer graphics software and the algorithm for graphics rendering and control have been developed rapidly. The contents of graphics are varied from rendering, transformation and dipping of different kinds of basic graphics to realistic graphics rendering and animation design. Interactive graphic imput, which is the basis of graphics rendering and animation design, has a direct offect on the efficiency and result of animation design. With respect to some key techniques for animation design, this paper adopts an integer algorithm without float data and dividing operation, designs many methods of rapid graphics input, discusses deformation model technique with which every scattering point in object is varying. Key frame is produced according to parameter given, then the technique of parametric animation with interpolating graphics, animation background design and its realization are investigated in detail. Finally, a prototype system of animation design is presented.
