  8. History – Early days of film • 1895 Auguste and Louis Lumiere, "Workers Leaving the Lumiere Factory in Lyon-Montplaisir“ • 1899 First magnetic recording of sound is achieved. • 1908 Emile Cohl, "Fantasmagorie." BPC: Art and Computation – Summer 2007

  9. Animation - Techniques • Stop-motion animation (puppets / objects / clay models) • Drawing and inking cel’s • Rotoscoping • Computer-assisted • Computer-generated BPC: Art and Computation – Summer 2007

  10. 2D animation in 3D scene • Image sequence mapped onto object in scene BPC: Art and Computation – Summer 2007

  11. 3D motion as animation - models BPC: Art and Computation – Summer 2007

  12. 3D motion as animation BPC: Art and Computation – Summer 2007

  13. Animation - timing • Speed of action • Synchronization of actions • Synchronization with sound • Sound track recorded first • Animation made to match sound BPC: Art and Computation – Summer 2007

  14. Animation – timing control • Fixed speed projection • Film 24 fps • Video 30 fps • Computer graphics • 60, 72, 75 Hz refresh rate • Image redraw may not match this speed • How vary action speed? BPC: Art and Computation – Summer 2007

  15. DAFFIE arp file • arp 2.0 • name playtime_seq • geom_path ./ • playspeed 10 • sound_path ../configs/playtime/ • frame • geom_show playtime00.obj • frame • geom_show playtime01.obj • frame • geom_show playtime02.obj • frame • geom_show playtime03.obj • frame • geom_show playtime04.obj • frame • geom_show playtime05.obj BPC: Art and Computation – Summer 2007

  16. More speed examples – 8 images BPC: Art and Computation – Summer 2007

  17. 12 Principles of Animation • Timing • Ease In and Out (or Slow In and Out) • Arcs • Anticipation • Exaggeration • Squash and Stretch • Secondary Action • Follow Through and Overlapping Action • Straight Ahead Action and Pose-To-Pose Action • Staging • Appeal • Personality BPC: Art and Computation – Summer 2007

  18. Summary BPC: Art and Computation – Summer 2007
