Animation is the process of making the illusion of motion and the illusion of change[Note 1] by means of the rapid succession of sequential images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon and beta movement, but the exact causes are still unclear.
There are some forms of animation that do not feature a rapid succession of sequential images, but these are usually not considered "true" or "full" animation. For instance, the physical movement of image parts through simple mechanics in magic lantern slides and the movement of the projector (the magic lantern) in phantasmagoria provided popular moving picture shows.
Animators are artists who specialize in the creation of animation. Animation can be recorded with either analogue media, a flip book, motion picture film, video tape, digital media, including formats with animated GIF, Flash animation, and digital video. To display animation, a digital camera, computer, or projector are used along with new technologies that are produced.
Animation methods include traditional animation, and methods that use stop motion animation of two and three-dimensional objects, paper cutouts, puppets, and clay figures. Images display in a rapid succession, usually 24, 25, 30, or 60 frames per second. Computer animation processes generating animated images with the general term computer-generated imagery (CGI). 3D animation uses computer graphics, while 2D animation is used for stylistic, low bandwidth and faster real-time renderings.

Early examples of attempts to capture the phenomenon of motion into a still drawing can be found in paleolithic cave paintings, where animals are often depicted with multiple legs in superimposed positions, clearly attempting to convey the perception of motion.
A 5,200-year old pottery bowl discovered in Shahr-e Sukhteh, Iran has five sequential images painted around it that seem to show phases of a Persian Desert Ibex leaping up to nip at a tree.  
Ancient Chinese records contain several mentions of devices that were said to "give an impression of movement" to human or animal figures, these accounts are unclear and may only refer to the actual movement of the figures through space. They may, of course, refer to Chinese shadow puppets.
In the 19th century, the phenakistoscope (1832), zoetrope (1834) and praxinoscope (1877) were introduced. A thaumatrope (1824) is a simple toy with a small disk with different pictures on each side; a bird in a cage and is attached to two pieces of strings. The phenakistoscope was invented simultaneously by Belgian Joseph Plateau and Austrian Simon von Stampfer in 1831. The phenakistoscope consists of a disk with a series of images, drawn on radi evenly space around the center of the disk.
John Barnes Linnett patented the first flip book in 1868 as the kineograph. The common flip book were early animation devices that produced an illusion of movement from a series of sequential drawings, animation did not develop further until the advent of motion picture film and cinematography in the 1890s.
The cinématographe was a projector, printer, and camera in one machine that successfully showed moving pictures on a screen. It was invented by two of history's earliest filmmakers, Auguste and Louis Lumière, in 1894. The first animated projection (screening) was created in France, by Charles-Émile Reynaud, who was a French science teacher. Reynaud created the Praxinoscope in 1877 and the Théâtre Optique in December 1888. On 28 October 1892, he projected the first animation in public, Pauvre Pierrot, at the Musée Grévin in Paris. This film is also notable as the first known instance of film perforations being used. His films were not photographed, they were drawn directly onto the transparent strip. In 1900, more than 500,000 people had attended these screenings.
The first known film recorded on standard picture film that included animated sequences was the 1900 Enchanted Drawing, which was followed by the first entirely animated film—the 1906 Humorous Phases of Funny Faces by J. Stuart Blackton, who, because of that, is considered the father of American animation.
In Europe, the French artist Émile Cohl created the first animated film using what became known as traditional animation creation methods - the 1908 Fantasmagorie. The film largely consists of a stick figure moving about and encountering all kinds of morphing objects, including a wine bottle that transforms into a flower. There are also sections of live action in which the animator's hands enter the scene. The film was created by drawing each frame with black ink on white paper, shooting each frame, and then making negative prints, which gave the film a white-on-black chalkline effect.
More detailed hand-drawn animation, requiring a team of animators drawing each frame manually with detailed backgrounds and characters, were those directed by Winsor McCay, a successful newspaper cartoonist, including the 1911 Little Nemo, the 1914 Gertie the Dinosaur, and the 1918 The Sinking of the Lusitania. Gertie the Dinosaur was an early example of the character development in drawn animation.
During the 1910s, the production of animated short films typically referred to as "cartoons", became an industry of its own and cartoon shorts were produced for showing in movie theaters. The most successful producer at the time was John Randolph Bray, who, along with animator Earl Hurd, patented the cel animation process that dominated the animation industry for the rest of the decade.
El Apóstol (Spanish: "The Apostle") was a 1917 Argentine animated film utilizing cutout animation, and the world's first animated feature film. Unfortunately, a fire that destroyed producer Federico Valle's film studio incinerated the only known copy of El Apóstol, and it is now considered a lost film.
In 1958, Hanna-Barbera released The Huckleberry Hound Show, the first half hour television program to feature only in animation. Terrytoons released Tom Terrific that same year. Television significantly decreased public attention to the animated shorts being shown in theaters.
In 2008, the animation market was worth US$68.4 billion. Animation as an art and industry continues to thrive as of the mid-2010s because well-made animated projects can find audiences across borders and in all four quadrants. Animated feature-length films returned the highest gross margins (around 52%) of all film genres in the 2004–2013 timeframe.
Traditional animation (also called cel animation or hand-drawn animation) was the process used for most animated films of the 20th century. The individual frames of a traditionally animated film are photographs of drawings, first drawn on paper. To create the illusion of movement, each drawing differs slightly from the one before it. The animators' drawings are traced or photocopied onto transparent acetate sheets called cels, which are filled in with paints in assigned colors or tones on the side opposite the line drawings. The completed character cels are photographed one-by-one against a painted background by a rostrum camera onto motion picture film.
The traditional cel animation process became obsolete by the beginning of the 21st century. Today, animators' drawings and the backgrounds are either scanned into or drawn directly into a computer system. Various software programs are used to color the drawings and simulate camera movement and effects. The final animated piece is output to one of several delivery media, including traditional 35 mm film and newer media with digital video. The "look" of traditional cel animation is still preserved, and the character animators' work has remained essentially the same over the past 70 years. Some animation producers have used the term "tradigital" (a play on the words "traditional" and "digital") to describe cel animation that uses significant computer technology.
Examples of traditionally animated feature films include Pinocchio (United States, 1940), Animal Farm (United Kingdom, 1954), and The Illusionist (British-French, 2010). Traditionally animated films produced with the aid of computer technology include The Lion King (US, 1994), The Prince of Egypt (US, 1998), Akira (Japan, 1988), Spirited Away (Japan, 2001), The Triplets of Belleville (France, 2003), and The Secret of Kells (Irish-French-Belgian, 2009).
Full animation refers to the process of producing high-quality traditionally animated films that regularly use detailed drawings and plausible movement, having a smooth animation. Fully animated films can be made in a variety of styles, from more realistically animated works those produced by the Walt Disney studio (The Little Mermaid, Beauty and the Beast, Aladdin, The Lion King) to the more 'cartoon' styles of the Warner Bros. animation studio. Many of the Disney animated features are examples of full animation, as are non-Disney works, The Secret of NIMH (US, 1982), The Iron Giant (US, 1999), and Nocturna (Spain, 2007). Fully animated films are animated at 24 frames per second, with a combination of animation on ones and twos, meaning that drawings can be held for one frame out of 24 or two frames out of 24.
Limited animation involves the use of less detailed or more stylized drawings and methods of movement usually a choppy or "skippy" movement animation. Limited animation uses fewer drawings per second, thereby limiting the fluidity of the animation. This is a more economic technique. Pioneered by the artists at the American studio United Productions of America, limited animation can be used as a method of stylized artistic expression, as in Gerald McBoing-Boing (US, 1951), Yellow Submarine (UK, 1968), and certain anime produced in Japan. Its primary use, however, has been in producing cost-effective animated content for media for television (the work of Hanna-Barbera, Filmation, and other TV animation studios) and later the Internet (web cartoons).
Rotoscoping is a technique patented by Max Fleischer in 1917 where animators trace live-action movement, frame by frame. The source film can be directly copied from actors' outlines into animated drawings, as in The Lord of the Rings (US, 1978), or used in a stylized and expressive manner, as in Waking Life (US, 2001) and A Scanner Darkly (US, 2006). Some other examples are Fire and Ice (US, 1983), Heavy Metal (1981), and Aku no Hana (2013).
Live-action/animation is a technique combining hand-drawn characters into live action shots or live action actors into animated shots. One of the earlier uses was in Koko the Clown when Koko was drawn over live action footage. Other examples include Who Framed Roger Rabbit (US, 1988), Space Jam (US, 1996) and Osmosis Jones (US, 2001).
Stop motion animation
Stop-motion animation is used to describe animation created by physically manipulating real-world objects and photographing them one frame of film at a time to create the illusion of movement. There are many different types of stop-motion animation, usually named after the medium used to create the animation. Computer software is widely available to create this type of animation; however, traditional stop motion animation is usually less expensive and time-consuming to produce than current computer animation.
- Puppet animation typically involves stop-motion puppet figures interacting in a constructed environment, in contrast to real-world interaction in model animation. The puppets generally have an armature inside of them to keep them still and steady to constrain their motion to particular joints. Examples include The Tale of the Fox (France, 1937), The Nightmare Before Christmas (US, 1993), Corpse Bride (US, 2005), Coraline (US, 2009), the films of Jiří Trnka and the adult animated sketch-comedy television series Robot Chicken (US, 2005–present).
- Clay animation, or Plasticine animation (often called claymation, which, however, is a trademarked name), uses figures made of clay or a similar malleable material to create stop-motion animation.Laybourne 1998, pp. 150–151 The figures may have an armature or wire frame inside, similar to the related puppet animation (below), that can be manipulated to pose the figures. Alternatively, the figures may be made entirely of clay, in the films of Bruce Bickford, where clay creatures morph into a variety of different shapes. Examples of clay-animated works include The Gumby Show (US, 1957–1967) Morph shorts (UK, 1977–2000), Wallace and Gromit shorts (UK, as of 1989), Jan Švankmajer's Dimensions of Dialogue (Czechoslovakia, 1982), The Trap Door (UK, 1984). Films include Wallace & Gromit: The Curse of the Were-Rabbit, Chicken Run and The Adventures of Mark Twain.
- Strata-cut animation, Strata-cut animation is most commonly a form of clay animation in which a long bread-like "loaf" of clay, internally packed tight and loaded with varying imagery, is sliced into thin sheets, with the animation camera taking a frame of the end of the loaf for each cut, eventually revealing the movement of the internal images within.
- Cutout animation is a type of stop-motion animation produced by moving two-dimensional pieces of material paper or cloth. Examples include Terry Gilliam's animated sequences from Monty Python's Flying Circus (UK, 1969–1974); Fantastic Planet (France/Czechoslovakia, 1973) ; Tale of Tales (Russia, 1979), The pilot episode of the adult television sitcom series (and sometimes in episodes) of South Park (US, 1997) and the music video Live for the moment, from Verona Riots band (produced by Alberto Serrano and Nívola Uyá, Spain 2014).
- Model animation refers to stop-motion animation created to interact with and exist as a part of a live-action world. Intercutting, matte effects and split screens are often employed to blend stop-motion characters or objects with live actors and settings. Examples include the work of Ray Harryhausen, as seen in films, Jason and the Argonauts (1963), and the work of Willis H. O'Brien on films, King Kong (1933).
- Go motion is a variant of model animation that uses various techniques to create motion blur between frames of film, which is not present in traditional stop-motion. The technique was invented by Industrial Light & Magic and Phil Tippett to create special effect scenes for the film The Empire Strikes Back (1980). Another example is the dragon named "Vermithrax" from Dragonslayer (1981 film).
- Object animation refers to the use of regular inanimate objects in stop-motion animation, as opposed to specially created items.
- Graphic animation uses non-drawn flat visual graphic material (photographs, newspaper clippings, magazines, etc.), which are sometimes manipulated frame-by-frame to create movement. At other times, the graphics remain stationary, while the stop-motion camera is moved to create on-screen action.
- Brickfilm are a subgenre of object animation involving using Lego or other similar brick toys to make an animation. These have had a recent boost in popularity with the advent of video sharing sites, YouTube and the availability of cheap cameras and animation software.
- Pixilation involves the use of live humans as stop motion characters. This allows for a number of surreal effects, including disappearances and reappearances, allowing people to appear to slide across the ground, and other effects. Examples of pixilation include The Secret Adventures of Tom Thumb and Angry Kid shorts.
Computer animation encompasses a variety of techniques, the unifying factor being that the animation is created digitally on a computer. 2D animation techniques tend to focus on image manipulation while 3D techniques usually build virtual worlds in which characters and objects move and interact. 3D animation can create images that seem real to the viewer.
2D animation figures are created or edited on the computer using 2D bitmap graphics, created and edited using with 2D vector graphics. This includes automated computerized versions of traditional animation techniques, interpolated morphing, onion skinning and interpolated rotoscoping.
2D animation has many applications, including analog computer animation, Flash animation, and PowerPoint animation. Cinemagraphs are still photographs in the form of an animated GIF file of which part is animated.
Final line advection animation is a technique used in 2D animation, to give artists and animators more influence and control over the final product as everything is done within the same department. Speaking about using this approach in Paperman, John Kahrs said that "Our animators can change things, actually erase away the CG underlayer if they want, and change the profile of the arm."
3D animation is digitally modeled and manipulated by an animator. The animator usually starts by creating a 3D polygon mesh to manipulate. A mesh typically includes many vertices that are connected by edges and faces, which give the visual appearance of form to a 3D object or 3D environment. Sometimes, the mesh is given an internal digital skeletal structure called an armature that can be used to control the mesh by weighting the vertices. This process is called rigging and can be used in conjunction with keyframes to create movement.
Other techniques can be applied, mathematical functions (e.g., gravity, particle simulations), simulated fur or hair, and effects, fire and water simulations. These techniques fall under the category of 3D dynamics.
- Cel-shaded animation is used to mimic traditional animation using computer software. Shading looks stark, with less blending of colors. Examples include Skyland (2007, France), The Iron Giant (1999, United States), Futurama (Fox, 1999) Appleseed Ex Machina (2007, Japan), The Legend of Zelda: The Wind Waker (2002, Japan)
- Machinima – Films created by screen capturing in video games and virtual worlds. The term originated from the software introduction in the 1980s demoscene, as well as the 1990s recordings of the first-person shooter video game Quake.
- Motion capture is used when live-action actors wear special suits that allow computers to copy their movements into CG characters. Examples include Polar Express (2004, US), Beowulf (2007, US), A Christmas Carol (2009, US), The Adventures of Tintin (2011, US) kochadiiyan (2014, India).
- Photo-realistic animation is used primarily for animation that attempts to resemble real life, using advanced rendering that mimics in detail skin, plants, water, fire, clouds, etc. Examples include Up (2009, US), How to Train Your Dragon (2010, US), Ice Age (2002, US).
- Animatronics is the use of mechatronics to create machines that seem animate rather than robotic.
- Audio-Animatronics and Autonomatronics is a form of robotics animation, combined with 3-D animation, created by Walt Disney Imagineering for shows and attractions at Disney theme parks move and make noise (generally a recorded speech or song). They are fixed to whatever supports them. They can sit and stand, and they cannot walk. An Audio-Animatron is different from an android-type robot in that it uses prerecorded movements and sounds, rather than responding to external stimuli. In 2009, Disney created an interactive version of the technology called Autonomatronics.
- Linear Animation Generator is a form of animation by using static picture frames installed in a tunnel or a shaft. The animation illusion is created by putting the viewer in a linear motion, parallel to the installed picture frames. The concept and the technical solution were invented in 2007 by Mihai Girlovan in Romania.
- Chuckimation is a type of animation created by the makers of the television series Action League Now! in which characters/props are thrown, or chucked from off camera or wiggled around to simulate talking by unseen hands.
- Puppetry is a form of theatre or performance animation that involves the manipulation of puppets. It is very ancient and is believed to have originated 3000 years BC. Puppetry takes many forms, they all share the process of animating inanimate performing objects. Puppetry is used in almost all human societies both as entertainment – in performance – and ceremonially in rituals, celebrations, and carnivals. Most puppetry involves storytelling.
- Zoetrope is a device that produces the illusion of motion from a rapid succession of static pictures. The term zoetrope is from the Greek words ζωή (zoē), meaning "alive, active", and τρόπος (tropos), meaning "turn", with "zoetrope" taken to mean "active turn" or "wheel of life".
Other animation styles, techniques, and approaches
- Hydrotechnics: a technique that includes lights, water, fire, fog, and lasers, with high-definition projections on mist screens.
- Drawn on film animation: a technique where footage is produced by creating the images directly on film stock, for example by Norman McLaren, Len Lye and Stan Brakhage.
- Paint-on-glass animation: a technique for making animated films by manipulating slow drying oil paints on sheets of glass, for example by Aleksandr Petrov.
- Erasure animation: a technique using traditional 2D media, photographed over time as the artist manipulates the image. For example, William Kentridge is famous for his charcoal erasure films, and Piotr Dumała for his auteur technique of animating scratches on plaster.
- Pinscreen animation: makes use of a screen filled with movable pins that can be moved in or out by pressing an object onto the screen. The screen is lit from the side so that the pins cast shadows. The technique has been used to create animated films with a range of textural effects difficult to achieve with traditional cel animation.
- Sand animation: sand is moved around on a back- or front-lighted piece of glass to create each frame for an animated film. This creates an interesting effect when animated because of the light contrast.
- Flip book: a flip book (sometimes, especially in British English, called a flick book) is a book with a series of pictures that vary gradually from one page to the next, so that when the pages are turned rapidly, the pictures appear to animate by simulating motion or some other change. Flip books are often illustrated books for children, they also be geared towards adults and employ a series of photographs rather than drawings. Flip books are not always separate books, they appear as an added feature in ordinary books or magazines, often in the page corners. Software packages and websites are also available that convert digital video files into custom-made flip books.
- Character animation
- Special effects animation
The creation of non-trivial animation works (i.e., longer than a few seconds) has developed as a form of filmmaking, with certain unique aspects. One thing live-action and animated feature-length films do have in common is that they are both extremely labor-intensive and have high production costs.
The most important difference is that once a film is in the production phase, the marginal cost of one more shot is higher for animated films than live-action films. It is relatively easy for a director to ask for one more take during principal photography of a live-action film, but every take on an animated film must be manually rendered by animators (although the task of rendering slightly different takes has been made less tedious by modern computer animation). It is pointless for a studio to pay the salaries of dozens of animators to spend weeks creating a visually dazzling five-minute scene if that scene fails to effectively advance the plot of the film. Thus, animation studios starting with Disney began the practice in the 1930s of maintaining story departments where storyboard artists develop every single scene through storyboards, then handing the film over to the animators only after the production team is satisfied that all the scenes make sense as a whole.  While live-action films are now also storyboarded, they enjoy more latitude to depart from storyboards (i.e., real-time improvisation).
Another problem unique to animation is the necessity of ensuring that the style of an animated film is consistent from start to finish, even as films have grown longer and teams have grown larger. Animators, like all artists, necessarily have their own individual styles, but must subordinate their individuality in a consistent way to whatever style was selected for a particular film. Since the early 1980s, feature-length animated films have been created by teams of about 500 to 600 people, of whom 50 to 70 are animators. It is relatively easy for two or three artists to match each other's styles; it is harder to keep dozens of artists synchronized with one another.
This problem is usually solved by having a separate group of visual development artists develop an overall look and palette for each film before animation begins. Character designers on the visual development team draw model sheets to show how each character should look like with different facial expressions, posed in different positions, and viewed from different angles. On traditionally animated projects, maquettes were often sculpted to further help the animators see how characters would look from different angles.
Unlike live-action films, animated films were traditionally developed beyond the synopsis stage through the storyboard format; the storyboard artists would then receive credit for writing the film. In the early 1960s, animation studios began hiring professional screenwriters to write screenplays (while also continuing to use story departments) and screenplays had become commonplace for animated films by the late 1980s.
Criticism of animation has been common in media and cinema since its inception. With its popularity, a large amount of criticism has arisen, especially animated feature-length films. Many concerns of cultural representation, psychological effects on children have been brought up around the animation industry, which has remained rather politically unchanged and stagnant since its inception into mainstream culture.
As with any other form of media, animation too has instituted awards for excellence in the field. The original awards for animation were presented by the Academy of Motion Picture Arts and Sciences for animated shorts from the year 1932, during the 5th Academy Awards function. The first winner of the Academy Award was the short Flowers and Trees, a production by Walt Disney Productions. The Academy Award for a feature-length animated motion picture was only instituted for the year 2001, and awarded during the 74th Academy Awards in 2002. It was won by the film Shrek, produced by DreamWorks and Pacific Data Images. Disney/Pixar have produced the most films either to win or be nominated for the award. The list of both awards can be obtained here:
Several other countries have instituted an award for best animated feature film as part of their national film awards: Africa Movie Academy Award for Best Animation (since 2008), BAFTA Award for Best Animated Film (since 2006), César Award for Best Animated Film (since 2011), Golden Rooster Award for Best Animation (since 1981), Goya Award for Best Animated Film (since 1989), Japan Academy Prize for Animation of the Year (since 2007), National Film Award for Best Animated Film (since 2006). Also since 2007, the Asia Pacific Screen Award for Best Animated Feature Film has been awarded at the Asia Pacific Screen Awards. Since 2009, the European Film Awards have awarded the European Film Award for Best Animated Film.
The Annie Award is another award presented for excellence in the field of animation. Unlike the Academy Awards, the Annie Awards are only received for achievements in the field of animation and not for any other field of technical and artistic endeavor. They were re-organized in 1992 to create a new field for Best Animated feature. The 1990s winners were dominated by Walt Disney, however, newer studios, led by Pixar & DreamWorks, have now begun to consistently vie for this award. The list of awardees is as follows:
