Motion Blur
Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation. It results when the image being recorded changes during the recording of a single exposure, due to rapid movement or long-exposure photography, long exposure. Usages / Effects of motion blur Photography When a camera creates an image, that image does not represent a single instant of time. Because of technological constraints or artistic requirements, the image may represent the scene over a period of time. Most often this exposure time is brief enough that the image captured by the camera appears to capture an instantaneous moment, but this is not always so, and a fast moving object or a longer exposure time may result in blurring artifacts which make this apparent. As objects in a scene move, an image of that scene must represent an Integral, integration of all positions of those objects, as well as the camera's viewpoint, over the period of exposur ...

Star Rain In The Desert
A star is a luminous spheroid of plasma (physics), plasma held together by Self-gravitation, self-gravity. The List of nearest stars and brown dwarfs, nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night sky, night; their immense distances from Earth make them appear as fixed stars, fixed points of light. The most prominent stars have been categorised into constellations and asterism (astronomy), asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye—all within the Milky Way galaxy. A star's life star formation, begins with the gravitational collapse of a gaseous nebula of material largely comprising hydrogen, helium, and traces of heavier elements. Its stellar mass, total mass mainly determines it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unreal Tournament 3
''Unreal Tournament 3'' (''UT3'') is a first-person arena shooter video game developed by Epic Games and published by Midway Games. Part of the ''Unreal'' franchise, it is the fourth game in the '' Unreal Tournament'' series, and the eighth and final game overall; its name is in reflection of the game being the first in the franchise to use Unreal Engine 3. It was released on November 19, 2007, for Microsoft Windows, December 10 for the PlayStation 3, and on July 3, 2008, for the Xbox 360.

In vehicle maps, the player is equipped with a hover board, which allows players to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raster Image
upright=1, The Smiley, smiley face in the top left corner is a raster image. When enlarged, individual pixels appear as squares. Enlarging further, each pixel can be analyzed, with their colors constructed through combination of the values for red, green and blue. In computer graphics and digital photography, a raster graphic, raster image, or simply raster is a two-dimensional image or picture represented as a rectangular Matrix (mathematics), matrix or grid of pixels, viewable via a computer display, paper, or other display medium. A raster image is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats. The printing and prepress industries know raster graphics as contones (from "continuous tones"). In contrast, '' line art'' is usually implemented as vector graphics in digital systems. Many raster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitmap
In computing, a bitmap (also called raster) graphic is an image formed from rows of different colored pixels. A GIF is an example of a graphics image file that uses a bitmap. As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each pixel may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the array of pixels which constitute a digital graphic output device (a screen or monitor). In some contexts, the term ''bitmap'' implies one bit per pixel, whereas ''pixmap'' is used for images with multiple bits per pixel. A bitmap is a type of memory organization or image file format used to store digital images. The term ''bitmap'' comes from the computer programming terminology, meaning just a ''map of bits'', a spatially mapped array of bits. Now, along with ''pixmap'', it commonly refers to the similar concept of a spatially mapp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Image
A digital image is an image composed of picture elements, also known as pixels, each with '' finite'', '' discrete quantities'' of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with ''x'', ''y'' on the x-axis and y-axis, respectively. An image can be vector or raster type. By itself, the term "digital image" usually refers to raster images or bitmapped images (as opposed to vector images). Raster Raster images have a finite set of digital values, called ''picture elements'' or pixels. The digital image contains a fixed number of rows and columns of pixels. Pixels are the smallest individual element in an image, holding quantized values that represent the brightness of a given color at any specific point. Typically, the pixels are stored in computer memory as a raster image or raster map, a two-dimensional array of small integers. These values are often trans ...

2D Computer Graphics
2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models (such as 2D geometric models, text, and digital images) and by techniques specific to them. It may refer to the branch of computer science that comprises such techniques or to the models themselves. 2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies, such as typography, cartography, technical drawing, advertising, etc. In those applications, the two-dimensional image is not just a representation of a real-world object, but an independent artifact with added semantic value; two-dimensional models are therefore preferred, because they give more direct control of the image than 3D computer graphics (whose approach is more akin to photography than to typography). In many domains, such as desktop publishing, engineering, and business, a description of a document based on 2D computer graph ...

Stop Motion
Stop-motion (also known as stop frame animation) is an animated filmmaking and special effects technique in which objects are physically manipulated in small increments between individually photographed frames so that they will appear to exhibit independent motion or change when the series of frames is played back. Any kind of object can thus be animated, but puppets with movable joints (puppet animation) or clay figures (claymation) are most commonly used. Puppets, models or clay figures built around an armature are used in model animation. Stop motion with live actors is often referred to as pixilation. Stop motion of flat materials such as paper, fabrics or photographs is usually called cutout animation. Terminology The term "stop-motion", relating to the animation technique, is often spelled without a hyphen as "stop motion"—either standalone or as a compound modifier. Both orthographic variants, with and without the hyphen, are correct, but the hyphenated one is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Go Motion
Go motion is a variation of stop motion animation which incorporates motion blur into each frame involving motion. It was co-developed by Industrial Light & Magic and Phil Tippett. Stop motion animation can create a distinctive and disorienting staccato effect because the animated object is perfectly sharp in every frame, since each frame is shot with the object perfectly still. Real moving objects in similar scenes have motion blur because they move while the camera's shutter is open. Filmmakers use a variety of techniques to simulate motion blur, such as moving the model slightly during the exposure of each film frame, or placing a glass plate smeared with petroleum jelly in front of the camera lens to blur the moving areas. History In the 1920s, Ladislas Starevich started using this technique by the time he started making films in France. He moved the puppet or the set during the exposure of the frame to create motion blur. Some of this can be seen in films like ''The Midnight ...

Cel Animation
Traditional animation (or classical animation, cel animation, or hand-drawn animation) is an animation technique in which each frame is drawn by hand. The technique was the dominant form of animation of the 20th century, until there was a shift to computer animation in the industry, such as digital ink and paint, a modern form of traditional animation methods, and 3D computer animation. Process Writing and storyboarding Animation production usually begins after a story is converted into an animation film script, from which a storyboard is derived. A storyboard has an appearance somewhat similar to comic book panels, and is a shot by shot breakdown of the staging, acting and any camera moves that will be present in the film. The images allow the animation team to plan the flow of the plot and the composition of the imagery. Storyboard artists will have regular meetings with the director and may redraw or "re-board" a sequence many times before it meets final approval. Voic ...

Motion Lines
In comics and art more broadly, motion lines (also known as movement lines, action lines, speed lines, or zip ribbons) are the abstract lines that appear behind a moving object or person, parallel to its direction of movement, to make it appear as if it is moving quickly. They are common in Japanese manga and anime, of which ''Speed Racer'' is a classic example. Lines depicting wind and the trajectory of missiles appear in art as early as the 16th century. By the 19th century artists were drawing naturally occurring speed lines when showing the passage of an object through water or snow, but it was not until the 1870s that artists like Wilhelm Busch and Adolphe Willette began drawing motion lines to depict the movement of objects through air. The French artist Ernest Montaut is usually credited with the invention of ''speed lines''. He used the technique freely in his posters which were produced at a time when auto racing, speedboat racing and aircraft races were in their i ...

Temporal Anti-aliasing
Temporal anti-aliasing (TAA), also known as TXAA (a proprietary technology) or TMAA/TSSAA (''Temporal Super-Sampling Anti-Aliasing''), is a spatial anti-aliasing technique for computer-generated video that combines information from past frames and the current frame to remove jaggies in the current frame. In TAA, each pixel is sampled once per frame but in each frame the sample is at a different location within the frame. Pixels sampled in past frames are blended with pixels sampled in the current frame to produce an anti-aliased image. Although this method makes TAA achieve a result comparable to supersampling, the technique inevitably causes Ghosting (television), ghosting and blurriness to the image. TAA compared to MSAA Prior to the development of TAA, Multisample anti-aliasing, MSAA was the dominant anti-aliasing technique. MSAA samples (renders) only the edges of polygons, then averages the samples to produce the final pixel value, making it surprisingly efficient in GPU-bound ...

Computer Generated Imagery
Computer-generated imagery (CGI) is a specific-technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos and video games. These images are either static (i.e. still images) or dynamic (i.e. moving images). CGI both refers to 2D computer graphics and (more frequently) 3D computer graphics with the purpose of designing characters, virtual worlds, or scenes and special effects (in films, television programs, commercials, etc.). The application of CGI for creating/improving animations is called ''computer animation'', or ''CGI animation''. History The first feature film to use CGI as well as the composition of live-action film with CGI was ''Vertigo'', which used abstract computer graphics by John Whitney in the opening credits of the film. The first feature film to make use of CGI with live action in the storyline of the film was the 1973 film ''Westworld''. The first feature film to present a fully CGI character ...
