Principles of Animation

Principle	Description
Timing	It sets the pace and cadence of motion, which is pivotal for expressing weight, emotion, and authenticity.
Squash & Stretch	Distorts the form of objects in motion to communicate weight and suppleness, which is crucial for crafting fluid and dynamic animations.
Anticipation	Anticipates forthcoming actions by signaling movements in advance, enhancing animations’ credibility and organic feel.
Follow Through and Overlapping Action	Adds secondary motion to primary movements, mimicking the natural physics of movement and increasing realism; includes follow-through (continuation of motion after the main action) and overlapping action (different parts of an object moving at different rates).
Arcs	Objects follow curved paths during movement, and smooth arcs create natural and pleasing animations that guide the viewer’s eye and convey trajectory.
Staging	Clears the path for animations to unfold in a visually captivating way, steering viewer focus and expressing mood or emotion via composition, framing, and camera angles.
Exaggeration	Emphasizes and amplifies characters’ actions and expressions for added engagement and entertainment while maintaining realism; exaggeration helps convey emotions and messages effectively.
Solid Drawing	Utilizes traditional drawing principles to fashion credible three-dimensional objects and characters in animation; comprehending form, anatomy, and perspective is imperative for crafting convincing animations.
Appeal	Ensures characters and animations are visually attractive and charismatic to the audience, enhancing engagement and relatability; appealing characters captivate viewers’ attention and foster emotional connections.
Secondary Animation	Introduces supplementary motion to objects or characters, such as hair, attire, or accessories responding to primary movement; amplifies realism and visual allure by injecting layers and intricacies into animations.

Types of Computer Animation

2D Animation

Traditional Hand-Drawn Animation:

Traditional hand-drawn animation entails crafting every frame manually, often on paper or digital drawing tablets. Animators sketch pivotal poses known as “keyframes” and then interpolate “in-between frames” to achieve seamless motion. This method boasts a rich heritage in animation and remains prevalent in both indie and commercial productions.

Digital Cel Animation:

Digital cel animation, also termed raster-based animation, emulates the aesthetic of traditional cel animation using digital techniques. It involves generating characters and backgrounds as distinct layers, enabling animators to animate them autonomously for intricate movements and effects. Widely employed in TV shows, web series, and short films, digital cel animation offers versatility and efficiency.

Vector-Based Animation: Vector-based animation utilizes mathematical equations to produce images and animations rooted in geometric shapes, lines, and curves. Unlike pixel-dependent raster animation, vector animation maintains resolution independence, facilitating seamless scaling without losing quality. Flash animation, a prevalent vector-based animation, is widely used in web animations and interactive media.
