The document outlines the Twelve Principles of Animation developed by Disney animators Frank Thomas and Ollie Johnston. The principles are meant to produce animated characters that adhere to physics while also conveying emotion and character. Some of the key principles include squash and stretch to give a sense of weight and flexibility, anticipation to make actions appear more realistic, follow through and overlapping action so body parts continue moving after the main action stops, exaggeration to make movements look natural rather than mechanical, and appeal to give characters charisma.
Principles of Animation
- 1. Twelve Principles of Animation Developed by Frank Thomas and Ollie Johnston based on the work of Disney Studio animators from the 1930s.
- 2. The Illusion of Life (1981) Thomas and Johnston The purpose of the 12 principles was to produce an illusion of characters adhering to the basic laws of physics, but also dealing with emotional timing and character appeal of performance.
- 3. 1. Squash and Stretch The most important principle is “squash and stretch,” the purpose of which is to give a sense of weight and flexibility to drawn objects. It can be applied to simple objects, like a bouncing ball, or more complex constructions, like the musculature of a human face. 1878 Eadweard Muybridge Horse as another example 2. Anticipation Anticipation is used to prepare the audience for an action, and to make the action appear more realistic, eg. dancer jumping off the floor has to bend his knees first; a golfer making a swing has to swing the club back first.
- 4. 3. STAGING The mise-en-scene should clearly communicate the attitude, mood, reaction or idea of the character as it relates to the story and continuity of the narrative. Long, medium, or close up shots, and camera angles also helps tell the story. 4. POSE TO POSE “Pose to Pose” is planned out and charted with key drawings done at intervals throughout the scene. Size, volumes, and proportions are controlled this way, as is the action. (“Straight ahead animation” starts at the first drawing and works drawing to drawing to the end of a scene -- does not have the same spontaneity and freshness.
- 5. 5. FOLLOW THROUGH AND OVERLAPPING ACTION When the main body of the character stops all other parts continue to catch up to the main mass of the character, such as arms, long hair, clothing, coat tails or a dress, floppy ears or a long tail (these follow the path of action). Nothing stops all at once. 6. SLOW-OUT AND SLOW-IN As action starts, we have more drawings near the starting pose, one or two in the middle, and more drawings near the next pose. Fewer drawings make the action faster and more drawings make the action slower.
- 6. 7. ARCS All actions, with few exceptions (such as the animation of a mechanical device), follow an arc or slightly circular path. This is especially true of the human figure and the action of animals. Arcs give animation a more natural action and better flow. 8. SECONDARY ACTION This action adds to and enriches the main action and adds more dimension to the character animation, supplementing and/or re-enforcing the main action. Example: A character is angrily walking toward another character. The walk is forceful, aggressive, and forward leaning.
- 7. 9. TIMING Expertise in timing comes best with experience and personal experimentation, using the trial and error method in refining technique. The basics are: more drawings between poses slow and smooth the action. Fewer drawings make the action faster and crisper. 10. EXAGGERATION Exageration is a caricature of facial features, expressions, poses, attitudes and actions. Action traced from live action film can be accurate, but stiff and mechanical. In feature animation, a character must move more broadly to look natural.
- 8. 11. SOLID DRAWING The basic principles of drawing form, weight, volume solidity and the illusion of 3D apply to animation as it does to art drawings. One draws in the classical sense, using pencil sketches and drawings for reproduction of life. These are then transformed into color and movement giving the characters the illusion of 3D and 4D life; 3D being perspective and staging in space. 4D dimension is movement in time. 12. APPEAL A live performer has charisma. An animated character has appeal. Appealing animation does not mean just being cute and cuddly. All characters have to have appeal whether they are heroic, villainous, comic or cute.
