In an influential 1981 book, The Illusion of Life: Disney Animation, two Disney animators codified 12 principles of animation. They covered visual fundamentals, such as “squash and stretch”, and storytelling elements, like timing and anticipation. All 12 principles aim to reinforce the illusion that animated characters are real, living beings so the audience connects to them emotionally.
Using 3D animation software makes it easier to apply the 12 principles. For example, the software’s keyframes, motion paths and curve drawing all help to bolster the seventh principle of arcs, which can serve realism or amusing exaggeration. 3D modelling perfectly suits the 11th principle of solid drawing, in which weight, gravity, light and shadow are all intrinsic to working with 3D animation software.
