Avar (animation Variable)
An avar or animation variable (or hinge) is a variable controlling the position of part of an animated object, such as a character. The character "Woody" in the Disney•Pixar film ''Toy Story'' (1995) uses 712 avars (212 on his face alone). Successive sets of avars control all movement of the character from frame to frame. In development, they are used to define the junctions of a stick model. Later, they are incorporated into a full wire frame model or a model built of polygons. Finally, surfaces are added, requiring a lengthy process of rendering to produce the final scene. There are several ways of generating the avar values. Motion capture uses a real person acting out the part, tracked by a video camera. ''Toy Story'' uses no motion capture, manual control by a skilled animator can produce effects not easily carried out by a human actor.

Animation
Animation is a method by which still figures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI). 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 a stop motion technique to two- and three-dimensional objects like paper cutouts, puppets, or clay figures. A cartoon is an animated film, usually a short film, 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 a natural predator/prey relationship (e.g. cats and mice, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walt Disney Company
The Walt Disney Company, commonly known as Disney (), is an American multinational mass media and entertainment conglomerate headquartered at the Walt Disney Studios complex in Burbank, California. Disney was originally founded on October 16, 1923, by brothers Walt and Roy O. Disney as the Disney Brothers Studio; it also operated under the names the Walt Disney Studio and Walt Disney Productions before changing its name to the Walt Disney Company in 1986. Early on, the company established itself as a leader in the animation industry, with the creation of the widely popular character Mickey Mouse, who is the company's mascot, and the start of animated films. After becoming a major success by the early 1940s, the company started to diversify into live-action films, television, and theme parks in the 1950s. Following Walt's death in 1966, the company's profits began to decline, especially in the animation division. Once Disney's shareholders voted in Michael Eisner as ...

Wire Frame Model
A wire-frame model, also wireframe model, is a visual representation of a three-dimensional (3D) physical object used in 3D computer graphics. It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using (straight) lines or curves. The object is projected into screen space and rendered by drawing lines at the location of each edge. The term "wire frame" comes from designers using metal wire to represent the three-dimensional shape of solid objects. 3D wire frame computer models allow for the construction and manipulation of solids and solid surfaces. 3D solid modeling efficiently draws higher quality representations of solids than conventional line drawing. Using a wire-frame model allows for the visualization of the underlying design structure of a 3D model. Traditional two-dimensional views and drawings/renderings can be created by the appropriate rotation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rendering (computer Graphics)
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a ''scene file'' containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene. The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output. Rendering is one of the major sub-topics of 3D computer graphics, and in practice it is always connected to the others. It is the last major step in the ...

Scene (film)
A scene is a dramatic part of a story, at a specific time and place, between specific characters. The term is used in both filmmaking and theatre, with some distinctions between the two. Theatre In drama, a scene is a unit of action, often a subdivision of an act. French scene A "French scene" is a scene in which the beginning and end are marked by a change in the presence of characters onstage, rather than by the lights going up or down or the set being changed.George, Kathleen (1994) ''Playwriting: The First Workshop'', Focal Press, , p. 154 Obligatory scene From the French ''scène à faire'', an obligatory scene is a scene (usually highly charged with emotion) which is anticipated by the audience and provided by an obliging playwright. An example is ''Hamlet'' 3.4, when Hamlet confronts his mother. Film In filmmaking and video production, a scene is generally thought of as a section of a motion picture in a single location and continuous time made up of a serie ...

Motion Capture
Motion capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. In filmmaking and video game development, it refers to recording actions of human actors, and using that information to animate digital character models in 2-D or 3-D computer animation.Andrew Harris Salomon, Feb. 22, 2013, Backstage MagazineGrowth In Performance Capture Helping Gaming Actors Weather Slump Accessed June 21, 2014, "..But developments in motion-capture technology, as well as new gaming consoles expected from Sony and Microsoft within the year, indicate that this niche continues to be a growth area for actors.

Video Camera
A video camera is an optical instrument that captures videos (as opposed to a movie camera, which records images on film). Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required. In the second mode the images are recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but was gradually supplanted by optical disc, hard disk, and then flash memory. Recorded video is used in television production, and more often surveillance an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animation Database
An animation database is a database which stores fragments of animations or human movements and which can be accessed, analyzed and queried to develop and assemble new animations.S. Kuroki, "Walkthrough using Animation database MOVE" in ''Database and expert systems applications, Volume 4'' edited by Vladimír Marík, 1994 pages 760-763Kaoru Sumi "Interactive Storytelling System Using Recycle-Based Story Knowledge" in ''Interactive Storytelling: Second Joint International Conference on Interactive Digital Storytelling, ICIDS 2009'' by Ido A. Iurgel 2009 pages 74-8/ref> Given that the manual generation of a large amount of animation can be time consuming and expensive, an animation database can assist users in building animations by using existing components, and sharing animation fragments. Early examples of animation databases include the system MOVE which used an object oriented database. Modern animation databases can be populated via the extraction of skeletal animations from ...

Computer Generated Imagery
Computer-generated imagery (CGI) is the use of computer graphics to create or contribute to images in art, printed media, video games, simulators, and visual effects in films, television programs, shorts, commercials, and videos. The images may be static ( still images) or dynamic ( moving images), in which case CGI is also called '' computer animation''. CGI may be two-dimensional (2D), although the term "CGI" is most commonly used to refer to the 3-D computer graphics used for creating characters, scenes and special effects in films and television, which is described as "CGI animation". The first feature film to make use of CGI was the 1973 film '' Westworld''. Other early films that incorporated CGI include '' Star Wars'' (1977), '' Tron'' (1982), '' Golgo 13: The Professional'' (1983), '' The Last Starfighter'' (1984), '' Young Sherlock Holmes'' (1985) and '' Flight of the Navigator'' (1986). The first music video to use CGI was Dire Straits' award-winning " Money for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Animation
Computer animation is the process used for digitally generating animations. The more general term computer-generated imagery (CGI) encompasses both static scenes ( still images) and dynamic images ( moving images), while computer animation refers to moving images. Modern computer animation usually uses 3D computer graphics to generate a three-dimensional picture. The target of the animation is sometimes the computer itself, while other times it is film. Computer animation is essentially a digital successor to stop motion techniques, but using 3D models, and traditional animation techniques using frame-by-frame animation of 2D illustrations. Computer-generated animations can also allow a single graphic artist to produce such content without the use of actors, expensive set pieces, or props. To create the illusion of movement, an image is displayed on the computer monitor and repeatedly replaced by a new image that is similar to it but advanced slightly in time (usually at a ...
