自然界中的大部分运动都是某种形式的加减速, 如果能把加减速的过程表现出来, 画面就会更加自然和流畅. 用FlashMX制作动画时,我发现小于 100%的ease值并不是很有用. 如果画出加速变形中位置随时间的变化图形, 就会得到类似于下图p(t) =tn的方程曲线. 曲线中的斜率对应于速度, Most of the movements in nature are some form of acceleration and deceleration. If we can express the acceleration and deceleration processes, the picture will be more natural and smooth. When I use FlashMX to make animations, I find that the value of less than 100% is not very Useful. If you plot the change in position over time in an accelerated deformation, you get an equation curve similar to the following graph p(t) = tn. The slope in the curve corresponds to velocity,
