Inspired by the Richard Linklater movie A Scanner Darkly starring Keanu Reeves, which is based on the Philip K Dick novel of the same name.
Find A Scanner Darkly on AmazonI am not sure of the real facts but this extract was taken from Wikipedia:
After principal photography was finished, the film was transferred to Quicktime for a 15-month animation process: interpolated-rotoscoping. A Scanner Darkly was filmed digitally and then animated with Rotoshop, a proprietary graphics editing program created by Bob Sabiston. Rotoshop uses an animation technique called interpolated rotoscope, which was previously used in Linklater's film Waking Life. Rotoscoping in traditional cel animation originally involved tracing over film frame-by-frame. Rotoshop animation, however, makes use of vector keyframes, and interpolates the in-between frames automatically.
Does that make sense? It does to me.Originally, pre-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 This projection equipment is called a rotoscope, although this device has been replaced by computers in recent years. In the visual effects industry, the term rotoscoping refers to the technique of manually creating a matte for an element on a live-action plate so it may be composited over another background.
