8. BPC: Art and Computation – Fall 20068 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."

9. BPC: Art and Computation – Fall 20069 Animation - Techniques Stop-motion animation (puppets / objects / clay models) Drawing and inking cel’s Rotoscoping Computer-assisted Computer-generated

10. BPC: Art and Computation – Fall 200610 Animation – Less-common techniques Drawing / collage on film Drawing over time Ink / paint on glass Pinscreen Sand Silhouette / cutout

12. BPC: Art and Computation – Fall 200612 Animation example - traditional

13. BPC: Art and Computation – Fall 200613 2D animation in 3D scene Image sequence mapped onto object in scene

14. BPC: Art and Computation – Fall 200614 3D motion as animation - models

15. BPC: Art and Computation – Fall 200615 3D motion as animation

16. BPC: Art and Computation – Fall 200616 Another example - models

19. BPC: Art and Computation – Fall 200619 Animation example – slow

20. BPC: Art and Computation – Fall 200620 Animation - timing Speed of action Synchronization of actions Synchronization with sound –Sound track recorded first –Animation made to match sound

21. BPC: Art and Computation – Fall 200621 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?
