Animation is the creation of the appearance of movement or change by presenting images, drawings, objects, models or computer generated states in a controlled temporal sequence. The apparent movement results from the visual system integrating successive images into perceived continuous action, while the production process determines how those images or states are created. Animation encompasses numerous techniques, including drawn animation, stop motion, cut out methods, two dimensional digital animation, three dimensional computer animation, motion capture based workflows and procedural systems. It can be used for entertainment, education, scientific visualisation, simulation, advertising, interface feedback, training and many other purposes.
The history of Animation predates modern cinema and includes optical toys and sequential image experiments designed to create an impression of movement. Devices such as the thaumatrope, phenakistiscope and zoetrope demonstrated principles of sequential visual presentation before film animation became established. Early animated films developed techniques for producing repeated sequences of drawings, while studios progressively refined character design, timing, storyboarding, layout, inking, painting, compositing and sound synchronisation. Later developments in television, photocopying, digital tools and computer graphics changed production methods without eliminating traditional principles. Modern animation is therefore the result of several technological and artistic traditions rather than a single invention.
Timing and spacing are fundamental concepts in Animation. Timing concerns how long an action takes, while spacing concerns the distribution of positions between successive frames or states. Changing these relationships can make the same action appear heavy, light, fast, slow, elastic or abrupt. Animation practice also uses principles such as anticipation, staging, squash and stretch, follow through, overlapping action, arcs and secondary action. These principles are not restricted to one production method and can be adapted to digital or physical workflows. The animator controls change over time, allowing movement to communicate physical properties, personality, causality and attention that may not be obvious from static images alone.
Animation can be classified according to how movement is generated. In frame by frame methods, each frame or pose may be deliberately constructed. In keyframe systems, important states are defined and intermediate states are generated or refined. Stop motion physically changes objects between photographed frames. Two dimensional digital animation manipulates drawings, vector elements or raster assets, while three dimensional computer animation manipulates digital objects, rigs, cameras and environments. Procedural animation generates movement according to rules or simulations, and motion capture records physical performance for later use. These categories can also be combined within a single production, making modern animation workflows highly hybrid.
Animation serves both representational and abstract purposes. It can portray fictional characters, reconstruct historical events, explain scientific processes, demonstrate mechanical operations or visualise invisible phenomena. Medical and scientific animation can represent structures that cannot be directly observed, although such representations must distinguish measured evidence from illustrative interpretation. Educational animation can control pacing and sequence to make complex processes easier to follow. Simulation and training applications can reproduce procedures and environmental conditions. Advertising uses animation for products, identities and explanatory content, while entertainment uses it for narrative, performance and world building. The technique is therefore not inherently tied to a particular genre or audience.
Production usually begins with conceptual planning and may involve scripts, storyboards, character or object designs, layouts, timing plans and animatics. The production method then determines the required assets and stages. Traditional workflows may require drawings, exposure planning and compositing, while computer animation may require models, textures, rigs, cameras, lights and render settings. Post production can include editing, compositing, colour correction, sound and visual effects. Large productions divide responsibilities among specialised departments, whereas individual creators may perform the entire process. The complexity of an animation project therefore depends on its visual requirements, duration, frame rate, resolution, number of assets and degree of movement rather than simply the chosen animation category.
Animation differs from live action because movement is constructed rather than recorded continuously from physical reality, although animation can incorporate captured performances and real footage. It differs from static illustration because temporal change is an essential component. It also differs from video editing, which primarily selects and arranges recorded or rendered material, although animated sequences are commonly edited into larger productions. Common misconceptions include assuming that animation is inherently simplistic or intended only for children, despite extensive use in serious drama, documentary explanation, engineering, science, medicine, military training and commercial communication. The apparent simplicity of an animated image can conceal substantial planning, drawing, modelling, timing and technical work.
Animation has evolved from manually produced sequences to highly sophisticated digital pipelines, but many foundational principles remain stable because perception and communication still depend on timing, staging and visual clarity. Contemporary production can combine hand drawn artwork, scanned drawings, vector assets, three dimensional renders, simulations, motion capture and compositing within one project. Artificially generated or procedurally assisted systems can accelerate some tasks, but human decisions concerning acting, design, timing, composition and meaning remain important in many workflows. Animation is consequently best understood as a broad method of constructing controlled temporal change rather than as a single visual style or production technology.
