Study of interpolation algorithm based on velocity function

At present, key-frame animation is realized mainly via the computing of interpolating time under given parameters to build in-between frames (intermediate frames). Usual methods include linear interpolation method and higher order spine interpolation may seem stiff. Effect of in-between frames will influence the fluency of animation directly. This paper presents a new interpolation algorithm based on analyzing classical parameter interpolation algorithm. Acceleration curve and velocity curve is introduced in this algorithm to build in-between frames. Finally, this article implements a small animation prototype system via this algorithm to compare with other traditional methods, which shows that the animation is more smooth and realistic.
