Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time . The term can refer to anything from rendering an application's graphical user interface ( GUI ) to real-time image analysis , but is most often used in reference to interactive 3D computer graphics , typically using a graphics processing unit (GPU). One example of this concept is a video game that rapidly renders changing 3D environments to produce an illusion of motion.

72-469: Trolley Troubles is a 1927 animated short subject film, produced by Charles B. Mintz and George Winkler and directed by Walt Disney . The cartoon is the first appearance of Oswald the Lucky Rabbit , a character that Disney and Ub Iwerks created for Universal Pictures and Mintz. In the early summer of 1927, Walt Disney finished the first Oswald cartoon, entitled Poor Papa , but Universal

144-411: A stop motion technique to two- and three-dimensional objects like paper cutouts , puppets , or clay figures . A cartoon in the animation sense is an animated film, usually short, featuring an exaggerated visual style. The style takes inspiration from comic strips , often featuring anthropomorphic animals , superheroes , or the adventures of human protagonists. Especially with animals that form

216-490: A consistent way to whatever style is employed on a particular film. Since the early 1980s, teams of about 500 to 600 people, of whom 50 to 70 are animators, typically have created feature-length animated films. It is relatively easy for two or three artists to match their styles; synchronizing those of dozens of artists is more difficult. This problem is usually solved by having a separate group of visual development artists develop an overall look and palette for each film before

288-422: A dedicated Disneyana Fan Club (since 1984). Disneyland opened in 1955 and features many attractions that were based on Disney's cartoon characters. Its enormous success spawned several other Disney theme parks and resorts . Disney's earnings from the theme parks have relatively often been higher than those from their movies. As with any other form of media, animation has instituted awards for excellence in

360-426: A natural predator/prey relationship (e.g. cats and mice, coyotes and birds), the action often centers on violent pratfalls such as falls, collisions, and explosions that would be lethal in real life. A cartoon can also be a still humorous drawing, often with the same elements as animated cartoons but with still versions. The illusion of animation—as in motion pictures in general—has traditionally been attributed to

432-451: A new life on the small screen and by the end of the 1950s, the production of new animated cartoons started to shift from theatrical releases to TV series. Hanna-Barbera Productions was especially prolific and had huge hit series, such as The Flintstones (1960–1966) (the first prime time animated series), Scooby-Doo (since 1969) and Belgian co-production The Smurfs (1981–1989). The constraints of American television programming and

504-520: A separate background, computer animation is usually based on programming paths between key frames to maneuver digitally created figures throughout a digitally created environment. Analog mechanical animation media that rely on the rapid display of sequential images include the phenakistiscope , zoetrope , flip book , praxinoscope , and film. Television and video are popular electronic animation media that originally were analog and now operate digitally . For display on computers, technology such as

576-450: A true powerhouse of animation production, with its own recognizable and influential anime style of effective limited animation . Animation became very popular on television since the 1950s, when television sets started to become common in most developed countries. Cartoons were mainly programmed for children, on convenient time slots, and especially US youth spent many hours watching Saturday-morning cartoons . Many classic cartoons found

648-531: A very long history in automata . Electronic automata were popularized by Disney as animatronics . The word animation stems from the Latin animātiōn , stem of animātiō , meaning 'bestowing of life'. The earlier meaning of the English word is 'liveliness' and has been in use much longer than the meaning of 'moving image medium'. Long before modern animation began, audiences around the world were captivated by

720-409: A wide variety of styles, relatively often including stop motion and cutout animation techniques. Soviet Soyuzmultfilm animation studio, founded in 1936, produced 20 films (including shorts) per year on average and reached 1,582 titles in 2018. China, Czechoslovakia / Czech Republic, Italy, France, and Belgium were other countries that more than occasionally released feature films, while Japan became

792-460: Is a daunting task for traditional Von Neumann architecture -based systems. An early workaround to this problem was the use of sprites , 2D images that could imitate 3D graphics. Different techniques for rendering now exist, such as ray-tracing and rasterization . Using these techniques and advanced hardware, computers can now render images quickly enough to create the illusion of motion while simultaneously accepting user input. This means that

864-845: 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. Walt Disney and Ub Iwerks created a series of Alice Comedies (1923–1927), in which a live-action girl enters an animated world. Other examples include Allegro Non Troppo (Italy, 1976), Who Framed Roger Rabbit (US, 1988), Volere volare (Italy 1991), Space Jam (US, 1996) and Osmosis Jones (US, 2001). Real-time rendering Computers have been capable of generating 2D images such as simple lines, images and polygons in real time since their invention. However, quickly rendering detailed 3D objects

936-413: 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

1008-532: Is responsible for generating "scenes", or 3D settings that are drawn to a 2D display. This stage is implemented in software that developers optimize for performance. This stage may perform processing such as collision detection , speed-up techniques, animation and force feedback, in addition to handling user input. Collision detection is an example of an operation that would be performed in the application stage. Collision detection uses algorithms to detect and respond to collisions between (virtual) objects. For example,

1080-449: 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

1152-430: Is that parallel lines remain parallel after the transformation. Perspective projection utilizes the concept that if the distance between the observer and model increases, the model appears smaller than before. Essentially, perspective projection mimics human sight. Clipping is the process of removing primitives that are outside of the view box in order to facilitate the rasterizer stage. Once those primitives are removed,

1224-404: Is the best known and most extreme example. Since first being licensed for a children's writing tablet in 1929, their Mickey Mouse mascot has been depicted on an enormous amount of products , as have many other Disney characters. This may have influenced some pejorative use of Mickey's name , but licensed Disney products sell well, and the so-called Disneyana has many avid collectors, and even

1296-414: Is the foundation of real-time graphics. Its main function is to render a two-dimensional image in relation to a virtual camera, three-dimensional objects (an object that has width, length, and depth), light sources, lighting models, textures and more. The architecture of the real-time rendering pipeline can be divided into conceptual stages: application, geometry and rasterization . The application stage

1368-529: Is 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 like those produced by the Walt Disney studio ( The Little Mermaid , Beauty and the Beast , Aladdin , The Lion King ) to the more 'cartoon' styles of

1440-432: Is the process that was 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

1512-763: 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 (Japan, 2013). Live-action/animation

1584-525: 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 often animated on "twos", sometimes on "ones", which means that 12 to 24 drawings are required for a single second of film. Limited animation involves

1656-556: The animated GIF and Flash animation were developed. In addition to short films , feature films , television series , animated GIFs, and other media dedicated to the display of moving images, animation is also prevalent in video games , motion graphics , user interfaces , and visual effects . The physical movement of image parts through simple mechanics—for instance, moving images in magic lantern shows—can also be considered animation. The mechanical manipulation of three-dimensional puppets and objects to emulate living beings has

1728-479: The camera to the world for detailed rendering—this expensive operation can take hours or days to render a single frame. Real-time graphics systems must render each image in less than 1/30th of a second. Ray tracing is far too slow for these systems; instead, they employ the technique of z-buffer triangle rasterization . In this technique, every object is decomposed into individual primitives, usually triangles. Each triangle gets positioned, rotated and scaled on

1800-408: The entertainment industry . Many animations are either tradtional animations or computer animations made with computer-generated imagery (CGI). Stop motion animation , in particular claymation , has continued to exist alongside these other forms. Animation is contrasted with live-action film , although the two do not exist in isolation. Many moviemakers have produced films that are a hybrid of

1872-462: The flip book (1868), the praxinoscope (1877) and film . When cinematography eventually broke through in the 1890s, the wonder of the realistic details in the new medium was seen as its biggest accomplishment. It took years before animation found its way to the cinemas. The successful short The Haunted Hotel (1907) by J. Stuart Blackton popularized stop motion and reportedly inspired Émile Cohl to create Fantasmagorie (1908), regarded as

1944-439: The persistence of vision and later to the phi phenomenon and beta movement , but the exact neurological causes are still uncertain. The illusion of motion caused by a rapid succession of images that minimally differ from each other, with unnoticeable interruptions, is a stroboscopic effect . While animators traditionally used to draw each part of the movements and changes of figures on transparent cels that could be moved over

2016-400: The spatial dimensions ), adding to the computer graphics' degree of realism. Real-time previewing with graphics software , especially when adjusting lighting effects , can increase work speed. Some parameter adjustments in fractal generating software may be made while viewing changes to the image in real time. The graphics rendering pipeline ("rendering pipeline" or simply "pipeline")

2088-538: The 1960s, and European producers looking for affordable cel animators relatively often started co-productions with Japanese studios, resulting in hit series such as Barbapapa (The Netherlands/Japan/France 1973–1977), Wickie und die starken Männer/小さなバイキング ビッケ (Vicky the Viking) (Austria/Germany/Japan 1974), Maya the Honey Bee (Japan/Germany 1975) and The Jungle Book (Italy/Japan 1989). Computer animation

2160-554: The 3D scene into view space. In view space, the observer (camera) is typically placed at the origin. If using a right-handed coordinate system (which is considered standard), the observer looks in the direction of the negative z-axis with the y-axis pointing upwards and the x-axis pointing to the right. Projection is a transformation used to represent a 3D model in a 2D space. The two main types of projection are orthographic projection (also called parallel) and perspective projection . The main characteristic of an orthographic projection

2232-522: The Beast was the first animated film nominated for Best Picture , in 1991. Up (2009) and Toy Story 3 (2010) also received Best Picture nominations, after the academy expanded the number of nominees from five to ten. 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. Traits common to both live-action and animated feature films are labor intensity and high production costs. The most important difference

2304-712: The Friendly Ghost (1945), Warner Bros. Cartoon Studios ' Looney Tunes ' Porky Pig (1935), Daffy Duck (1937), Elmer Fudd (1937–1940), Bugs Bunny (1938–1940), Tweety (1942), Sylvester the Cat (1945), Wile E. Coyote and the Road Runner (1949), MGM cartoon studio 's Tom and Jerry (1940) and Droopy , Universal Cartoon Studios ' Woody Woodpecker (1940), Terrytoons / 20th Century Fox 's Mighty Mouse (1942), and United Artists ' Pink Panther (1963). In 1917, Italian-Argentine director Quirino Cristiani made

2376-594: The Tramp (1955) failed at the box office. For decades afterward, Disney would be the only American studio to regularly produce animated features, until Ralph Bakshi became the first to also release more than a handful features. Sullivan-Bluth Studios began to regularly produce animated features starting with An American Tail in 1986. Although relatively few titles became as successful as Disney's features, other countries developed their own animation industries that produced both short and feature theatrical animations in

2448-524: The US. Successful producer John Randolph Bray and animator Earl Hurd , patented the cel animation process that dominated the animation industry for the rest of the century. Felix the Cat , who debuted in 1919, became the first fully realized anthropomorphic animal character in the history of American animation. In 1928, Steamboat Willie , featuring Mickey Mouse and Minnie Mouse , popularized film-with-synchronized-sound and put Walt Disney 's studio at

2520-469: The 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

2592-521: 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 requirement to maintain a film's consistency from start to finish, even as films have grown longer and teams have grown larger. Animators, like all artists, necessarily have individual styles, but must subordinate their individuality in

2664-459: The application may calculate new positions for the colliding objects and provide feedback via a force feedback device such as a vibrating game controller. The application stage also prepares graphics data for the next stage. This includes texture animation, animation of 3D models, animation via transforms , and geometry morphing. Finally, it produces primitives (points, lines, and triangles) based on scene information and feeds those primitives into

2736-438: The current Wii remote) typically take much longer to achieve than comparable advancements in display devices. Another important factor controlling real-time computer graphics is the combination of physics and animation . These techniques largely dictate what is to be drawn on the screen—especially where to draw objects in the scene. These techniques help realistically imitate real world behavior (the temporal dimension , not

2808-714: The demand for an enormous quantity resulted in cheaper and quicker limited animation methods and much more formulaic scripts. Quality dwindled until more daring animation surfaced in the late 1980s and in the early 1990s with hit series, the first cartoon of The Simpsons (1987), which later developed into its own show (in 1989) and SpongeBob SquarePants (since 1999) as part of a "renaissance" of American animation. While US animated series also spawned successes internationally, many other countries produced their own child-oriented programming, relatively often preferring stop motion and puppetry over cel animation. Japanese anime TV series became very successful internationally since

2880-399: The director has complete control of what has to be drawn on each frame, which can sometimes involve lengthy decision-making. Teams of people are typically involved in the making of these decisions. In real-time computer graphics, the user typically operates an input device to influence what is about to be drawn on the display. For example, when the user wants to move a character on the screen,

2952-422: 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 90 years. Some animation producers have used the term "tradigital" (a play on

3024-868: The field. Many are part of general or regional film award programs, like the China's Golden Rooster Award for Best Animation (since 1981). Awards programs dedicated to animation, with many categories, include ASIFA-Hollywood 's Annie Awards , the Emile Awards in Europe and the Anima Mundi awards in Brazil. Apart from Academy Awards for Best Animated Short Film (since 1932) and Best Animated Feature (since 2002), animated movies have been nominated and rewarded in other categories, relatively often for Best Original Song and Best Original Score . Beauty and

3096-458: The first feature-length film El Apóstol (now lost ), which became a critical and commercial success. It was followed by Cristiani's Sin dejar rastros in 1918, but one day after its premiere, the film was confiscated by the government. After working on it for three years, Lotte Reiniger released the German feature-length silhouette animation Die Abenteuer des Prinzen Achmed in 1926,

3168-406: The forefront of the animation industry. Although Disney Animation's actual output relative to total global animation output, has always been very small; the studio has overwhelmingly dominated the "aesthetic norms" of animation ever since. The enormous success of Mickey Mouse is seen as the start of the golden age of American animation that would last until the 1960s. The United States dominated

3240-408: The geometry stage of the pipeline. The geometry stage manipulates polygons and vertices to compute what to draw, how to draw it and where to draw it. Usually, these operations are performed by specialized hardware or GPUs. Variations across graphics hardware mean that the "geometry stage" may actually be implemented as several consecutive stages. Before the final model is shown on the output device,

3312-611: The humour it can provide. Some animated characters in commercials have survived for decades, such as Snap, Crackle and Pop in advertisements for Kellogg's cereals. Tex Avery was the producer of the first Raid " Kills Bugs Dead " commercials in 1966, which were very successful for the company. Apart from their success in movie theaters and television series, many cartoon characters would also prove lucrative when licensed for all kinds of merchandise and for other media. Animation has traditionally been very closely related to comic books . While many comic book characters found their way to

3384-411: The image quality that real-time graphics can produce. GPUs are capable of handling millions of triangles per frame, and modern DirectX / OpenGL class hardware is capable of generating complex effects, such as shadow volumes , motion blurring , and triangle generation , in real-time. The advancement of real-time graphics is evidenced in the progressive improvements between actual gameplay graphics and

3456-435: The late 1980s, in a style similar to traditional cel animation. The so-called 3D style, more often associated with computer animation, became the dominant technique following the success of Pixar's Toy Story (1995), the first computer-animated feature in this style. Most of the cel animation studios switched to producing mostly computer-animated films around the 1990s, as it proved cheaper and more profitable. Not only

3528-421: The magic of moving characters. For centuries, master artists and craftsmen have brought puppets, automatons , shadow puppets , and fantastical lanterns to life, inspiring the imagination through physically manipulated wonders. In 1833, the stroboscopic disc (better known as the phenakistiscope ) introduced the principle of modern animation, which would also be applied in the zoetrope (introduced in 1866),

3600-467: The model is transformed onto multiple spaces or coordinate systems . Transformations move and manipulate objects by altering their vertices. Transformation is the general term for the four specific ways that manipulate the shape or position of a point, line or shape. In order to give the model a more realistic appearance, one or more light sources are usually established during transformation. However, this stage cannot be reached without first transforming

3672-824: The oldest extant animated feature. In 1937, Walt Disney Studios premiered their first animated feature Snow White and the Seven Dwarfs , still one of the highest-grossing traditional animation features as of May 2020 . The Fleischer studios followed this example in 1939 with Gulliver's Travels with some success. Partly due to foreign markets being cut off by the Second World War, Disney's next features Pinocchio , Fantasia (both 1940), Fleischer Studios' second animated feature Mr. Bug Goes to Town (1941–1942) and Disney's feature films Cinderella (1950), Alice in Wonderland (1951) and Lady and

3744-510: The oldest known example of a complete traditional (hand-drawn) animation on standard cinematographic film. Other great artistic and very influential short films were created by Ladislas Starevich with his puppet animations since 1910 and by Winsor McCay with detailed hand-drawn animation in films such as Little Nemo (1911) and Gertie the Dinosaur (1914). During the 1910s, the production of animated " cartoons " became an industry in

3816-429: The pre-rendered cutscenes traditionally found in video games. Cutscenes are typically rendered in real-time—and may be interactive . Although the gap in quality between real-time graphics and traditional off-line graphics is narrowing, offline rendering remains much more accurate. Real-time graphics are typically employed when interactivity (e.g., player feedback) is crucial. When real-time graphics are used in films,

3888-768: The screen (which is often the case in Japan, where many manga are adapted into anime ), original animated characters also commonly appear in comic books and magazines. Somewhat similarly, characters and plots for video games (an interactive form of animation that became its own medium) have been derived from films and vice versa. Some of the original content produced for the screen can be used and marketed in other media. Stories and images can easily be adapted into children's books and other printed media. Songs and music have appeared on records and as streaming media. While very many animation companies commercially exploit their creations outside moving image media, The Walt Disney Company

3960-622: The screen, and rasterizer hardware (or a software emulator) generates pixels inside each triangle. These triangles are then decomposed into atomic units called fragments that are suitable for displaying on a display screen . The fragments are drawn on the screen using a color that is computed in several steps. For example, a texture can be used to "paint" a triangle based on a stored image, and then shadow mapping can alter that triangle's colors based on line-of-sight to light sources. Real-time graphics optimizes image quality subject to time and hardware constraints. GPUs and other advances increased

4032-458: 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. In modern traditionally animated films, animators' drawings and the backgrounds are either scanned into or drawn directly into a computer system. Various software programs are used to color

4104-425: 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. Traditional animation (also called cel animation or hand-drawn animation)

4176-468: The system updates the character's position before drawing the next frame. Usually, the display's response-time is far slower than the input device—this is justified by the immense difference between the (fast) response time of a human being's motion and the (slow) perspective speed of the human visual system . This difference has other effects too: because input devices must be very fast to keep up with human motion response, advancements in input devices (e.g.,

4248-684: The trolley crashes into a river and becomes a raft. Oswald uses a big stick to row it downstream. The short was released on December 11, 2007, on Walt Disney Treasures: The Adventures of Oswald the Lucky Rabbit . A restored version of the short was released on Disney+ on September 7, 2023, as part of Disney's 100th Anniversary. Animation Animation is a filmmaking technique by which still images are manipulated to create moving images . In traditional animation , images are drawn or painted by hand on transparent celluloid sheets ( cels ) to be photographed and exhibited on film. Animation has been recognized as an artistic medium, specifically within

4320-404: The trolley underneath her. Oswald thinks that all is well until the hill gets steep. Oswald uses a goat to get the trolley up the hill, then down the hill. The trolley unexpectedly goes onto a bumpy road, tossing the kids out of the trolley. Oswald prays that he will live, takes off his foot, kisses it and rubs it on his head (as per the saying that a rabbit's foot gives a good luck). Eventually,

4392-462: The two . As CGI increasingly approximates photographic imagery , filmmakers can easily composite 3D animations into their film rather than using practical effects for showy visual effects (VFX). Computer animation can be very detailed 3D animation , while 2D computer animation (which may have the look of traditional animation) can be used for stylistic reasons, low bandwidth, or faster real-time renderings . Other common animation methods apply

4464-847: 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

4536-507: The user can respond to rendered images in real time, producing an interactive experience. The goal of computer graphics is to generate computer-generated images , or frames , using certain desired metrics. One such metric is the number of frames generated in a given second. Real-time computer graphics systems differ from traditional (i.e., non-real-time) rendering systems in that non-real-time graphics typically rely on ray tracing . In this process, millions or billions of rays are traced from

4608-565: The value had increased to an estimated US$ 370 billion. Animated feature-length films returned the highest gross margins (around 52%) of all film genres between 2004 and 2013. Animation as an art and industry continues to thrive as of the early 2020s. The clarity of animation makes it a powerful tool for instruction, while its total malleability also allows exaggeration that can be employed to convey strong emotions and to thwart reality. It has therefore been widely used for other purposes than mere entertainment. During World War II, animation

4680-401: The very popular 3D animation style was generated with computers, but also most of the films and series with a more traditional hand-crafted appearance, in which the charming characteristics of cel animation could be emulated with software, while new digital tools helped developing new styles and effects. In 2010, the animation market was estimated to be worth circa US$ 80 billion. By 2021,

4752-683: 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), Lucky and Zorba (Italy, 1998), and The Illusionist (British-French, 2010). Traditionally animated films produced with the aid of computer technology include The Lion King (US, 1994), Anastasia (US, 1997), 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

4824-482: The world market of animation with a plethora of cel-animated theatrical shorts. Several studios would introduce characters that would become very popular and would have long-lasting careers, including Walt Disney Productions ' Goofy (1932) and Donald Duck (1934), Fleischer Studios / Paramount Cartoon Studios ' Out of the Inkwell ' Koko the Clown (1918), Bimbo and Betty Boop (1930), Popeye (1933) and Casper

4896-543: Was gradually developed since the 1940s. 3D wireframe animation started popping up in the mainstream in the 1970s, with an early (short) appearance in the sci-fi thriller Futureworld (1976). The Rescuers Down Under was the first feature film to be completely created digitally without a camera. It was produced using the Computer Animation Production System (CAPS), developed by Pixar in collaboration with The Walt Disney Company in

4968-474: Was not very satisfied. They had expected a more Charlie Chaplin -like character and thought Oswald was too elderly and too fat.
