Document Summary
Animating an articulated 3d character currently requires manual rigging to specify its internal skeletal structure and to de ne how the input motion deforms its surface. We present a method for ani- mating characters automatically. Given a static character mesh and a generic skeleton, our method adapts the skeleton to the character and attaches it to the surface, allowing skeletal motion data to an- imate the character. Because a single skeleton can be used with a wide range of characters, our method, in conjunction with a library of motions for a few skeletons, enables a user-friendly animation system for novices and children. Our prototype implementation, called pinocchio, typically takes under a minute to rig a character on a modern midrange pc. Modeling in 3d is becoming much easier than before. User-friendly systems such as teddy [igarashi et al. 1999] and cosmic blobs (http://www. cosmicblobs. com/) have made the creation of 3d characters accessible to novices and children.
