  3. Motion Notation • 1700 “Choregraphie”, Feuillet • 1852 “Stenochoregraphie”, Arthur Saint Leon • 1928 “Notation of Movement”, Margaret Morris • 1928 “Schrifttanz”, Rudolf von Laban • 1940 “Kinetography Laban” (Labanotation) • 1950’s Eshkol & Wachmann: mathematical notation • 1956 “Choreology”, Joan and Rudolf Benesh

  4. Motion Notation • Labanotation “Labanotation”, Ann Hutchinson

  5. Motion Notation • Labanotation “Labanotation”, Ann Hutchinson

  6. Motion Notation • Labanotation “Labanotation”, Ann Hutchinson

  7. Animation History • Film Animation • 1914 Windsor McCay – Gertie the Dinosaur • 1923 Walt Disney, “Alice in Wonderland” • 1928 Walt Disney, “Mickey Mouse” • 1969 Burtnyk & Wein, NRCC, computer keyframing • 1988 Pixar “Tin Toy” • 1995 Pixar “Toy Story”, full-length CG film • 2001 Square “Final Fantasy”, CG people

  8. Traditional Animation (from “The Illusion of Life”Frank Thomas and Ollie Johnson)

  10. Traditional Animation • (from “The Illusion of Life”Frank Thomas and Ollie Johnson)

  11. Traditional Animation (from “The Illusion of Life” Frank Thomas and Ollie Johnson)

  12. 3D Animation (keyframing) • p. 44, “[digital] character animation 2”, • G. Maestri p. 151, “[digital] character animation 2”, G. Maestri

  13. 3D Animation (keyframing) • Issues • complete control over motion • rigging character • time consuming • not real-time

  15. Motion Capture • Muybridge, 1884 • Rotoscoping (Figure from “Animals in Motion”, Muybridge)

  16. Motion Capture • Muybridge (Figure from “Animals in Motion”, Muybridge)

  17. Motion Capture (Figure from Ascension Inc.)

  18. Motion Capture (Figure from Northern Digital Inc.)

  19. Motion Capture • Issues • modifying mocap data • building graphs • annotation of data • data cleanup • data compression
