Historical Perspective
 Perception of Images in Motion
 Conventional Animation
 Early
 Disney
 Stop Motion
 History of Computer Animation
Perception
Positive afterimage: imprint of image in the
visual system just viewed (look into flash of a
camera)
Our brain sees a sequence of images as
motion
persistence of vision: lower limit for
continuous viewing
flicker rate: rate of playback in order to
achieve continuous illusion (depends on
lighting, viewing distance etc.)
flicker: perception of continuous imagery fails
playback rate: (related to flicker) number of
images displayed per second
motion blur: movement is too quick to track.
Doesn’t come automatically in animation
strobing: too fast movement of object in
animation, where motion blur in not considered
sampling rate: (related to strobing) number of
different images per second
not every displayed frame needs to be re-drawn/rendered
from scratch
Convential Animation – Early
Hand-drawn, 2D images
George Melies (1896)
– multiple exposure and stop-motion
– make objects (dis)appear, change shape
Pioneers in film animation:
Emile Cohl, J. Stuart Blackton
– animation of smoke (special FX) in 1900
– first animated cartoon in 1906
Winsor McCay
– first celebrated animator
– 1911 - Little Nemo
– 1914 - Gertie the Dinosaur
VAN EATON GALLERIES, SHERMAN OAKS, CA
– redrew each complete image and filmed individually
– early cartoons included live action with animated
characters (rotoscope)
John Bray
– major technical developments
– patents of techniques
– 1914: use of translucent cels (compositing of multiple
layers)
– peg system for registration (simplify panning - parallel
movement of camera to drawings)
From Bray’s studios:
– Max Fleischer (Betty Boop)
– Paul Terry (Terrytoons)
– George Stallings (Tom and Jerry)
– Walter Lantz (Woody Woodpecker, Chilly Willy)
Convential Animation: Disney
Walt Disney
– many technical innovations
– advancing the art form
– storyboard to review
– pencil sketches to review motion
– first sound - Steamboat Willie (1928)
Major innovation - multiplane camera (p8, Parent)
– each plane moves in 6 directions
– camera can move closer or farther
– more effective zoom
– illusion of depth and a 3D sense
– motion blur (camera lens stays open)
Disney created unique personalities
– Mickey Mouse, Pluto, Goofy, …
– mind of the character is the driving force
developed mood pieces: Fantasia (1940)
Convential Animation - Stop Motion
1930s - proliferation of animation studios
Willis O’Brian - King Kong (1933)
Ray Harryhausen - Mighty Joe Young
(1949), Jason and the Argonauts (1963),
Sindbad and the Eye of the Tiger (1977),
Clash of the Titans (1981)
Tim Burton - Nightmare Before Christmas
(1993), James and the Giant Peach (1996)
Nick Park (clay-mation) - Wallace and
Gromit (1992-1995)
