Anavar oranimation variable (orhinge) is a variable controlling the position of part of ananimated object, such as a character. The character "Woody" in theDisney•Pixar filmToy Story (1995) uses 712 avars (212 on his face alone).[1] 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 fullwire frame model or a model built of polygons. Finally, surfaces are added, requiring a lengthy process ofrendering to produce the finalscene.
There are several ways of generating the avar values.Motion capture uses a real person acting out the part, tracked by avideo camera.Toy Story uses no motion capture, manual control by a skilled animator can produce effects not easily carried out by a human actor.
