Animation

• traditional cel (celluloid transparencies) animation
  • animation table with registration pins to hold/align cels
  • stack of individual cels on the table then the background image (drawn separate from the foreground cels)
  • some animation created by moving the front cels relative to the other cels and the background
  • key frames drawn by best artist
  • in-between frames drawn by rest of staff
  • for items that repeat over time build loops (ie the foot and leg motions of a person walking)
  • reuse the loop for all repeats
• stop motion animation - (Claymation (take picture, move hand take picture ...))
• crude method - rebuild/redraw each frame
• morphing - key frames with points marked for morphing for in-betweening (can be either in 2D or 3D)
• use physics to describe motion
• use movies of motion or computer logs from real motion
• parametric and/or real world computer models of the objects/systems
• build loops for a object/action, reuse the loops (with parametric synchronization)
