Disney’s Classic Animated Films and Rotoscoping
While Disney has made some of the most popular animated features of all time, they had the good sense to use the most advanced animation technology available at that time - rotoscoping. Rotoscoping is a technique in which animators trace over footage, frame by frame, for use in live-action and animated films. The recorded live-action film images were projected onto a frosted glass panel and re-drawn by an animator. This projection equipment is called a rotoscope, although this device was eventually replaced by computers. It is the vintage predecessor to the computer simulation techniques James Cameron used for his Avatar characters.
