摘要
对计算机辅助动画制作过程中关键帧的插补技术进行了研究。线性插值法通过给定的起始帧和结束帧对应点之间的直线距离算出中间插值帧。移动点约束条件插补法利用随时间空间变化的曲线与彩体上的点相关联,来控制关键帧上对应控制点的轨迹以厦动态特征。骨架插补法是将图形抽象成骨架,然后进行插补。
Do same research on in-betweening techniques in computer aided animation. Linear interpolation technique has done in-betweening by calculating linear distance of corresponding points of start and end key frames. The principle of moving point constraints in-betweening technique is to associate a curve varing in space and time with some points of the animated object. The curve controls the trajectory and the dynamics of the point. Skeleton technique does in-betweening based on sheletons of graphics.
