Slide 1

´╗┐Workshop Computer Animation Arjan Egges Lecture #2: History of Animation

Slide 2

Introduction Animate = "Offer life to" Adding the measurement of time to representation Animator indicates development of items through time and space

Slide 3

Two primary classifications Computer-helped liveliness 2D & 2 1/2 D Inbetweening Inking, virtual camera, overseeing information, and so on Computer created activity Low level techniques Precisely determining movement High level systems Describe general movement conduct

Slide 4

Introduction Low-level strategies Shape interjection Helps the artist fill in the points of interest of the movement sufficiently given data Animator has a genuinely particular thought of target movement High-level methods Generate a movement given an arrangement of principles or imperatives Object movement is controlled by a model/calculation Fairly refined calculation, for example, physically-based movement

Slide 5

Introduction Another method for taking a gander at this: level of deliberation Very low-level: artist hues each pixel exclusively in each casing Very-abnormal state: tell the PC "make a motion picture around a pooch" Challenge lies in creating instruments that permit artists to energize on various levels

Slide 6

Perception Eye/mind collects pictures and translates them as nonstop development Persistence of vision : grouping of still pictures appeared at a sufficiently quick rate to instigate impression of constant symbolism Eye holds visual engraving once jolt is evacuated "positive afterimages" Persistence of vision is not tirelessness of movement

Slide 7

Perception Persistence of vision lower bound: Playback rate of pictures Critical glint recurrence Persistence of movement has an upper bound: Object moves too rapidly Motion obscure Two essential rates: Playback/revive rate Sampling/upgrade rate

Slide 8

The good \'ol days Persistence of vision: found in the 1800s. Zoetrope Flipbook Thaumatrope

Slide 9

The good \'ol days End of the 19 th centure presented moving picture by utilizing a projector. Enchantment Lantern and shadow manikins Zoopraxinoscope (zoetrope + projector) Kinetograph First film viewer

Slide 10

The good \'ol days Animation motion picture pioneers J. Stuart Blackton (smoke impact, 1900) First vivified toon in 1906 Used a blackboard for drawing and eradicating outlines Emile Cohl (Fantasmogorie, 1908) Winsor McCay (Little Nemo) Each picture redrawn on rice paper and after that recorded

Slide 11

The good \'ol days Major specialized improvements by John Bray (1910): compositing different layers of drawings into a last picture (celluloid) utilizing grayscale Drawing foundation on long sheet of paper for panning Max Fleischer (Betty Boop), Walter Lantz (Woody Woodpecker) Fleischer protected rotoscoping in 1915

Slide 12

The good \'ol days First enlivened character: Felix the Cat (Otto Messmer) in mid 1920s. Disney came around end 1920s, presenting various developments Storyboards Pencil draws for checking on movement Multiplane camera Using sound & shading

Slide 13

Multiplane Camera Move scene layers freely of camera Six headings of development for every plane

Slide 14

Multiplane camera Powerful apparatus: More compelling zoom Move closer view picture to the side Parallax impact Moving planes at various rates Adding profundity signals Blur the pictures on more inaccessible planes Introduce movement obscure by quick moving planes

Slide 15

The good \'ol days Sound was included without precedent for Steamboat Willie (1928) Disney advanced thought that brain of the character was the main thrust of the activity Analysis of genuine movement

Slide 16

MGM and Warner Brothers, and so forth

Slide 17

Other Media Animation Computer liveliness is regularly contrasted with stop movement liveliness Puppet liveliness Willis O\'Brian (King Kong) Ray Harryhausen (Might joe Yong, Jason and the Argonauts)

Slide 18

Other Media Animation Claymation Sand activity Physical item is controlled, picture caught, rehash

Slide 19

Production of Animation Preliminary Story load up Detailed story Key Frames Test shot Pencil test Inbetweening Inking Coloring Computer Animation essentially tails this pipeline

Slide 20

Computer Animation as Animation Lasseter interpreted customary standards of liveliness to PC movement Lasseter is routinely prepared illustrator Worked at Disney before going to Pixar Many praised activitys Knick-talent (oscar-winning)

Slide 21

Computer Animation Research In Research labs NYIT Still edge from Gumby liveliness by Hank Grebe and Dick Lundin, 1984.

Slide 22

Computer Animation Research University of Utah Films on strolling and talking figure Animated hand and enlivened face (1972) University of Pennsylvania Human figure liveliness (Norm Badler) MIRALab, Geneva Virtual Humans (Daniel & Nadia Thalmann)

Slide 23

Pioneering activity motion pictures Pixar Luxo Jr. (1986) first PC activity to be assigned for an Academy Award Red\'s Dream (1987) Tin Toy (1988) first PC liveliness to win an Academy Award Knick Knack (1989)

Slide 24

Early CG in film Future World (1976) Star Wars (1977) Tron (1982, MAGI) Supposed to resemble a PC The Last Starfighter (1984) Use CG set up of models Willow (1988, ILM) Morphing video First computerized blue screen matte extraction The Abyss (1989, ILM) Lawnmower man (1992, Xaos, Angel Studios) Hollywood\'s perspective of VR

Slide 25

Early CG in film Jurassic Park (1993, ILM) Forrest Gump (1994, Digital Domain) Insert CG ping pong ball Babe (1995, Rhythm & Hues) Move mouths of creatures & fill in foundation Toy Story (1995, Pixar & Disney) First full length completely CG 3D activity

Slide 26

Early CG on TV Reboot (1995, Limelight Ltd. BLT Productions) Similar goal of "inside PC" First completely 3D Sat. morning toon Babylon 5 (1995) Routinely utilized CG models as standard elements Simpsons (1995 PDI)

Slide 27

More late films with CG Final dream (2001) Fully 3D reenacted environment Lord of the Rings (2001-2003) One of the principal motion pictures utilizing swarms (Massive) Polar express (2004) Fully movement catch based The Shrek motion pictures (2001, 2004, 2007) Avatar (2009)
