Automatic Rigging and Animation of 3D Characters.
Author:"Animating an articulated 3D character currently requires manual rigging to specify its internal skeletal structure and to define how the input motion deforms its surface. This is a tedious process and we describe a method to automate it. Our motivation is to be able to build a system for children and other non-professional animators that, when presented with, for example, an unfamiliar quadruped character, can immediately execute commands such as "make it walk like a dog." To achieve this, we need to be able to embed an existing skeleton into the volume inside a character mesh, and then to attach the mesh vertices to the bones of the embedded skeleton. To our knowledge, this has not been previously attempted."
