9. BPC: Art and Computation – Summer 20079 Animation - Techniques Stop-motion animation (puppets / objects / clay models) Drawing and inking cel’s Rotoscoping Computer-assisted Computer-generated

10. BPC: Art and Computation – Summer 200710 2D animation in 3D scene Image sequence mapped onto object in scene

11. BPC: Art and Computation – Summer 200711 3D motion as animation - models

12. BPC: Art and Computation – Summer 200712 3D motion as animation

13. BPC: Art and Computation – Summer 200713 Animation - timing Speed of action Synchronization of actions Synchronization with sound –Sound track recorded first –Animation made to match sound

14. BPC: Art and Computation – Summer 200714 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?
