Abstract

A novel algorithm and approach to kinematic inbetweening for motion animation is proposed. To represent motion of a character in computer animation, a parametric curve is used to specify motion path of character while a velocity profile curve describing the varied speed of character along the path. Given the motion path and speed, kinematic inbetweening technique is executed to generate motion inbetweens from which skeleton sequences for character animation are obtained by inverse kinematical technique. In this paper, the principle and a novel algorithm for kinematic inbetweening is proposed and several demonstrations provided.
