Transcript of "ITMA06 Introduction to Animation"

  1. 1. Learning Outcomes ITMA Lecture 06 Introduction to Animation • Why does animation work? • Parameter: FPS Krates Ng Fall 2008 • Your first animation! Krates Ng 2008 2 The Egyptians did it first POV • 2000 BC, found the 1st comic strip on Egyptian wall decoration. • Persistence of Vision • Behaviors of our eyes and brains. • In 1824, Paul Roget examined POV scientifically. • Led to some interesting optical toys. Krates Ng 2008 3 Krates Ng 2008 4 Phenakistoscope Phenakistoscope (2) • In 1832, invented by Joseph Plateau • View through slots facing a mirror • Turning disc animates images Krates Ng 2008 5 Krates Ng 2008 6 1
  2. 2. Zeotrope and Praxinoscope Thaumatrope • Zeotrope: William Horner, 1834 • 1824, John Paris. • Praxinoscope: Emile Reynaud, 1877 • Or 1828, Paul Roget Zeotrope Praxinoscope Krates Ng 2008 7 Krates Ng 2008 8 The photography of motion • Eadweard Muybridge (1830-1904) – Father of motion picture. Flipbook • A series of picture held together and flip it with your thumb. • You can do it simply using a stack of “Post-it”. • Observe the images when you flip it fast and slow. Krates Ng 2008 9 Krates Ng 2008 10 Frame Rate / Frame per sec. (FPS) Conclusion • What happen to the images when you turn • Why we can see animation/movie? the Thaumatrope fast and slow? – POV • What happen to the images when you flip the flipbook fast and slow? • What determines the smoothness of an • FPS ↑  Animation smoother, less flicker animation (apart from your drawing skills)? • But, FPS ↑  Production cost ↑ – Frame Rate in Frame Per Sec. (FPS) Krates Ng 2008 11 Krates Ng 2008 12 2
  3. 3. More Optical Illusions (1)… References • Chronology of animation from 1879: www.public.iastate.edu/~rllew/chrnearl.html • Optical toys web.inter.nl.net/users/anima/index.htm • History of movie www.filmsite.org/filmh.html Rotating Snakes Krates Ng 2008 13 Krates Ng 2008 14 More Optical Illusions (2)… More Optical Illusions (3)… Krates Ng 2008 Rotating Tops 15 Krates Ng 2008 16 More Optical Illusions (4)… History of photography/movie • First photos were taken in 1820s by a Frenchman, Nicephore Niepce. • Fox Talbot in England produced the 1st photographic negative in 1835. • In 1889, celluloid film was introduced by Eastman Kodak Co. More available at: http://www.ritsumei.ac.jp/~akitaoka/index-e.html • 1893, Thomas Edison invented Kinetoscope. Krates Ng 2008 17 Krates Ng 2008 18 3
  4. 4. How? Activity (1) Bouncing ball reference: http://www.idleworm.com/how/anm/01b/bball.shtml • Produce your first animation! • Bouncing ball animation Krates Ng 2008 19 Krates Ng 2008 20 Questions Activity (2) • Why the ball is deformed in some pictures? • Stick Figure Animation • Use Pivot Stick Animator to produce a stick animation no less than 80 frames (individual) or • How do you make the animation smoother? 120 frames (pair) • How do you make the ball move faster? http://www.geocities.com/peter_bone_uk/pivot.html Krates Ng 2008 21 Krates Ng 2008 22 4
