30 How to Create Expressive Animation ? Bill Tytla at the Walt Disney Studio, June 28, 1937. "There is no particular mystery in animation.., it's really very simple, it is about the hardest in the world to do"

31 Principles of Animation The Illusion of Life, by Thomas Johnson and Ollie Johnson

32 Principles of Animation The Illusion of Life, by Thomas Johnson and Ollie Johnson Principles of Traditional Animation Applied to 3D Computer Animation, John Lasseter, Siggraph 87.

33 11 Principles Squash and Stretch Timing Anticipation Staging Follow Through Pose to Pose Slow In, Show Out Arcs Exaggeration Secondary Action Appeal

34 Squash and Stretch Movement emphasizes rigidity Preserve volume

35 Squash and Stretch

36

37

38 Timing Timing, or the speed of an action gives meaning to movement Weight, Scaling, Emotion

39 Timing Two keyframes of a head No: hit by a tremendous force ONE: hit by a frying pan TWO: nervous tic THREE: dodging a brick FOUR: a crisp order Move it! FIVE: friendly Come on-hurry SIX: tracing a pretty girl SEVEN: Getting a better look EIGHT: Searching for the peanut butter NINE: Considering thoughtfully TEN: stretch a sore muscle

40 Anticipation The preparation of an action Revealing Indicating Speed, Weight Directing Attention

41 Aniticipation

42 Anticipation

43

44 Staging Staging is the presentation of an idea so that it is completely and unmistakably clear. Readability Personality Mood

45 Follow Through The termination of an action Weight and drag Initiation Overlapping

46 Pose-to-Pose Keyframes

47 Slow In, Slow Out The spacing of the inbetweens Non-linear interpolation

48 Slow In, Slow Out The spacing of the inbetweens Non-linear interpolation

49 Arcs The visual path of action from one extreme to another is always described by an arc

50 Arcs

51 Exaggeration Exaggerate the essence of the action Action, emotion, shape, color, sound, …

52 Secondary Action An action that results directly from another action

53 Secondary Action

54 Appeal The animated character has appeal. A quality of charm Pleasing design Simplicity It doesnt mean that the character/animation should be realistic.

55 Luxo Jr. vs Final Fantasy

56 Uncanny Valley Human psychological reaction to animation Coined by Japanese roboticist Masahiro Mori Emotional response against similarity to human appearance and movement

57 Uncanny Valley

58 CG Techinques for Animation What can CG do for the principles ? Keyframing Timing, Arc, Slow In & Out Geometric deformation Squash and Stretch Rendering Staging Physics based techniques Secondary Action

59 Physics-based Techniques Rigid body 10-plank_test_withcontact_c.avi 1000ring.avi tank_straight_comp.avi Deformable body buddha_gear.avi warping.mov hair.mov movie1.avi BreakingObjects.avi,Materials.avi BreakingObjects.aviMaterials.avi Fluid Burning_Paper.avi glass00.avi melting_ice.avi torus_cage.avi pouring4.avi water-curtain-front_new.avi goop-et-web.avi Derivative Particles.mov vfx.mov, rnd.mov vfx.movrnd.mov
