Abstract

Techniques that give animators the direct control they are accustomed to with key frame animation, while providing for path-based motion. A key frame animation-based interface is used to achieve path-based motion with rotation animation variable value correction using additional animation variables for smoothing. The value of the additional animation variables for smoothing can be directly controlled using a tangent handle in a user interface.
