Cloning Skeleton-driven Animation to Other Models

Abstract

3D animation has been manipulated widely in movies and video games nowadays. To make a 3D model move, traditionally, requires animators’ efforts to edit the key poses of the model. It is a time-consuming task, especially when dealing with an imposing scene such as those full of different animals or soldiers. In this paper, we propose an efficient technique to clone skeleton-driven animation data from one to another model, including skeleton, binding weights and key-frame poses. With the proposed technique, users will only need to specify few common features between the source model and the target ones, and our system can transfer the animation automatically. The cloned animation can also be refined by adjusting either the cloned skeleton, binding weights, or key poses. In these settings, we can speed up the process of making crowd motion sequences and enable the reuse of animation.
