  3. The Power of Motion

  4. Principles of Animation

  5. Persistence of Vision

  6. Phi

  7. Frames Flickering Principles of Animation

  8. 2D animation: the visual changes that bring an image alive occur on the flat Cartesian x and y axes of the screen. • 2 ½ D animation: where shadowing, highlights, and forced perspective provide an illusion of depth, the third dimension. • 3D animation: software creates a virtual realm in three dimensions, and changes (motion) are calculated along all three axes (x, y, and z). Animation by Computer

  9. Path animation

  10. Path Animation

  11. When creating an animation Animation Techniques

  12. Cel Animation

  13. Cel animation: Also known as hand drawn animation uses a number of celluloid sheets to drawn frames. • One minute of cel animation requires 1,440 frames to be drawn. Cel Animation

  14. Cel Animation Process

  15. Keyframes and Tweening

  16. Pencil Test

  17. Computer animation uses the principles of cel animation • Computer 3D animation adds more focus on modeling, lighting and rendering. Computer Animation

  18. Kinematics is the study of the movement and motion of structures that have joints, such as a walking man. Kinematics

  19. Inverse kinematics: is the process by which you link objects such as hands to arms and define their relationships and limits (for example, elbows cannot bend backward). Inverse Kinematics

  20. Squash and stretch • Anticipation • Staging • Straight ahead action and pose to pose • Follow through and overlapping action • Slow in and slow out • Arcs • Secondary action • Timing • Exaggeration • Solid drawing • Appeal 12 principles of animation
