An avar or animation variable is a variable controlling the position of part of an animated object, such as a character. The character "Woody" in the Disney•Pixar film Toy Story (1995) uses 712 avars. Successive sets of avars control all movement of the character from frame to frame. In development, they are used to define the junctions of a stick model. Later, they are incorporated into a full wire frame model or a model built of polygons. Finally, surfaces are added, requiring a lengthy process of rendering to produce the final scene.
