Skeletal animation *

Skeletal : "Skeletal animation is a technique in computer animation in which a character is represented in two parts: a surface representation used to draw the character (called skin or mesh) and a hierarchical set of interconnected bones (called the skeleton or rig) used to animate (pose and key frame) the mesh.While this technique is often used to animate humans or more generally for organic modelling, it only serves to make the animation process more intuitive and the same technique can be used to control the deformation of any object — a spoon, a building, or a galaxy. This technique is used in virtually all animation systems where simplified user interfaces allows animators to control often complex algorithms and a huge amount of geometry; most notably through inverse kinematics and other "goal-oriented" techniques. In principle, however, the intention of the technique is never to imitate real anatomy or physical processes, but only to control the deformation of the mesh data."
