The complicated process of creating Toy Story in 3D
The New York Times has an interested read this morning depicting the monumental task of adding a third dimension to the Toy Story and Toy Story 2 double feature released last Friday. The 3D Toy Story, now in theaters, was created by adding a virtual second camera to the one camera view used in the 2D Toy Story films of the last decade.
Without changing any of the film's action, Pixar's 3-D specialists, or stereographers, returned to each frame of the film and virtually placed a second camera next to the original, creating left-eye and right-eye views of the scene. Then all of the scenes were re-rendered in the computer with this additional perspective.
The process of resurrecting the old data took 4 months, while adding a third dimension took a further 6 months per film!
