An avar or animation variable (or hinge) 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 (212 his the face alone).〔(How We Do it - Index )〕 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. There are several ways of generating the avar values. Motion capture uses lights or markers on a real person acting out the part, tracked by a video camera. ''Toy Story'' uses no motion capture, manual control by a skilled animator can produce effects not easily carried out by a human actor. == See also == * Animation * Animation database * Computer generated imagery * Computer animation * Pixar 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Avar (animation variable)」の詳細全文を読む スポンサード リンク
