摘要
论述了计算机辅助动画制作过程中的图象插补技术，线性插值法通过起始帧和结束帧对应点间的直线距离算出中间插补画面。骨架插值法根据图形的骨架进行中间帧插补，移动点约束条件插补法利用随时间和空间变化的曲线与形体上的点相联系，并控制关键帧上点的轨迹及动态特性。
Th15 paper has discussed in-betweening techniques in computer aided animation. Linearinterpolation technique has done in-betweening by calculating linear distance of correspond-ing points of start and end keyframes. Skeleton technique does in-betweening based on skele-tons of graphics. The principle of moving point constraints in-betweening technique is to as-sociate a curve (i.e. a moving point)varing in space and time with some points of the animat-ed object. The curve controls the trajectory and the dynamics of the point.
