he part-rhino, part-centaur Cyclops, the serpent woman, and the two-headed Roc bird from Sinbad; or, from Jason, the harpies that are a cross between gargoyles and pterodactyls, and the seven-headed Hydra and its spawn” (ILM). In traditional stop motion (still practiced by Henry Selick in marvels like The Nightmare Before Christmas and James and the Giant Peach), the camera records a series of subtly different poses rather than actual shifting, so the resulting flow of images is inherently surreal -- ultra-sharp and jerky. That is the reason that an audience can instantly tell when a creature has been animated in this way. If one was to look at a frame of film of a person running, they would see that the legs of the person in the frame are blurred. This was the thing that gave stop-motion away. If one were to pause a movie and look at a single frame, one would see that the movement was perfectly focussed and not blurred at all. Starting with the movie Dragonslayer in 1980, and later used on the Taumtaum creatures in Return of the Jedi, Tippett helped develop a new method of animating at ILM which became know as ‘Go Motion’.In go motion, motorized and computer-governed rods were attached to the models that were being animated. When each frame was shot, the rod moved to blur the movement on the film, thus giving a more realistic look of motion.In 1992, Tippett was hired to do the animation work for the film, Jurassic Park. He did not know it then, but he was about to embark on a journey that would forever change the way he, and many other artists like him worked. At the time, the director of Jurassic Park, Steven Speilberg thought that Tippett’s ‘Go Motion’ would do the trick for all the effects he wanted. Go motion was state-of-the-art in the early ’90s. But there was trouble on the horizon. One of the computer artists at ILM presented Spielberg and company with a rough computer animation of the ...
