7.1 Principles of Animation

Animation brings stories to life through movement and visual magic. These fundamentals are the secret sauce that makes characters and objects feel real, even in fantastical worlds. From squash and stretch to timing tricks, animators use these tools to create believable motion.

Character animation takes center stage, breathing life into protagonists and sidekicks alike. Staging and appeal techniques ensure the audience's eyes go where they should, while clever design choices make characters unforgettable. These principles work together to craft engaging animated experiences.

• Squash and stretch adds flexibility and life to objects while maintaining volume during shape changes (bouncing ball)
• Anticipation prepares audience for action creating expectation and readability (wind-up before a punch)
• Staging presents ideas clearly focusing attention on most important elements (character silhouette)
• Straight ahead action and pose to pose approaches animation process sequentially or with key poses first
• Follow through and overlapping action continues motion after main action stops with different parts moving at varied rates (hair swinging)
• Slow in and slow out adds natural feel through gradual acceleration and deceleration (pendulum swing)
• Arcs create organic and realistic motion following circular paths (swinging arm)
• Secondary action supports main action adding complexity (blinking while talking)
• Timing controls speed and rhythm affecting weight and size perception (heavy vs light objects)
• Exaggeration pushes movements beyond realism enhancing character personality (cartoon takes)
• Solid drawing maintains consistent volume and perspective in 2D and 3D (rotating objects)
• Appeal creates charm and interest in characters engaging audience emotionally (Disney princesses)

Timing and spacing techniques

• Timing determines perceived speed of movement through frame count between actions
• Spacing controls acceleration and deceleration by distributing in-between frames
• Frame rate considerations: film standard 24 fps, animation on twos 12 unique drawings per second
• Ease-in and ease-out create natural motion through gradual start and stop of movements
• Holds emphasize or show reaction using static or moving pauses in action
• Slow motion and fast motion effects manipulate timing for dramatic impact altering weight and force perception
• Rhythmic timing enhances musicality and flow creating patterns in movement (dance sequences)

Character animation fundamentals

• Squash and stretch emphasizes flexibility in organic forms while maintaining volume (jumping character)
• Anticipation in character movement creates readability through wind-up before action (preparing to run)
• Secondary action adds depth through hair, clothing movement, or supporting facial expressions
• Character weight and balance shown through squash and stretch for mass and anticipation for balance shifts
• Emotional expression uses exaggerated anticipation for surprise or subtle secondary actions for complex emotions
• Character personality established through unique timing, spacing, and consistent use of animation principles

Staging and appeal in animation

• Staging for clarity uses silhouettes and avoids overlapping elements that create confusion
• Composition in animation applies rule of thirds for balanced frame layout and leads eye through scene transitions
• Color and contrast emphasize important elements and create depth through value differences
• Camera angles and movement showcase action and enhance storytelling (low angle for powerful character)
• Character design balances simplicity with distinctive features creating memorable and relatable characters (Mickey Mouse)
• Environmental design supports without overpowering animation using perspective and scale to enhance depth
• Timing and rhythm in visual storytelling maintains audience engagement through paced scenes and visual beats
