Colour-cycling
Color cycling, also known as palette shifting, is a technique used in computer graphics in which colors are changed in order to give the impression of animation. This technique was mainly used in early computer games, as storing one image and changing its palette required less memory and processor power than storing the animation as several frames. Examples of use * The Windows 9x boot screen used color cycling to provide animation. * The 3D maze screensaver included with earlier versions of Windows used color cycling to animate the four fractal textures available. * The Amiga Boing Ball cycled the ball's checkerboard pattern between red and white to create the illusion of the ball rotating. The same technique was used by Sonic the Hedgehog 3 on the Sega Genesis in its bonus stages featuring a rolling checkerboard sphere. * ''SimCity 2000'' made extensive use of this technique: every building with animation had its animation provided by color cycling. This was used to provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grafx2
GrafX2 is a bitmap graphics editor inspired by the Amiga programs Deluxe Paint and Brilliance. It is free software and distributed under the GPL-2.0-only license. History GrafX2 was an MS-DOS program developed by Sunset Design from 1996 to 2001 . It was distributed as freeware, and was one of the most used graphics editor in the demoscene. The development stopped due the lack of time of the developers. So they released the sourcecode under the GPL-2.0-only license. A Windows port was done by the Eclipse demogroup and presented at the State of the art party in 2004, but the sourcecode for this version does not seem to be available anywhere. In 2007, a project was started to port the sourcecode from the original MS-DOS version to the Simple DirectMedia Layer library. The goal was to provide a pixel art editing tool for Linux, but SDL also allowed easy ports to many other platforms, including Windows. The project development continued on this new version to add the features ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Graphics
Computer graphics deals with generating images with the aid of computers. Today, computer graphics is a core technology in digital photography, film, video games, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research. Some topics in computer graphics include user interface design, sprite graphics, rendering, ray tracing, geometry processing, computer animation, vector graphics, 3D modeling, shaders, GPU design, implicit surfaces, visualization, scientific c ...

Animation
Animation is a method by which image, still figures are manipulated to appear as Motion picture, moving images. In traditional animation, images are drawn or painted by hand on transparent cel, 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 Computer animation#Animation methods, 3D animation, while Traditional animation#Computers and traditional animation, 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 cutout animation, paper cutouts, puppets, or Clay animation, clay figures. A cartoon is an animated film, usually a short film, featuring an cartoon, exaggerated visual style. The style takes inspiration from comic strips, often featuring anthropomorphi ...

Computer Games
A personal computer game, also known as a PC game or computer game, is a type of video game played on a personal computer (PC) rather than a video game console or arcade machine. Its defining characteristics include: more diverse and user-determined gaming hardware and software; and generally greater capacity in input, processing, video and audio output. The uncoordinated nature of the PC game market, and now its lack of physical media, make precisely assessing its size difficult. In 2018, the global PC games market was valued at about $27.7 billion. Home computer games became popular following the video game crash of 1983, leading to the era of the "bedroom coder". In the 1990s, PC games lost mass-market traction to console games, before enjoying a resurgence in the mid-2000s through digital distribution on services such as Steam and GOG.com. Newzoo reports that the ''PC gaming sector'' is the third-largest category (and estimated in decline) across all platforms , with the ...

Palette (computing)
In computer graphics, a palette is the set of available colors from which an image can be made. In some systems, the palette is fixed by the hardware design, and in others it is dynamic, typically implemented via a color lookup table (CLUT), a correspondence table in which selected colors from a certain color space's color reproduction range are assigned an index, by which they can be referenced. By referencing the colors via an index, which takes less information than needed to describe the actual colors in the color space, this technique aims to reduce data usage, including processing, transfer bandwidth, RAM usage, and storage. Images in which colors are indicated by references to a CLUT are called indexed color images. Description As of 2019, the most common image colorspace in graphics cards is the RGB color model with 8 bits per pixel color depth. Using this technique, 8 bits per pixel are used to describe the luminance level in each of the RGB channels, therefore 24 b ...

Video Frame
In filmmaking, video production, animation, and related fields, a frame is one of the many ''still images'' which compose the complete ''moving picture''. The term is derived from the historical development of film stock, in which the sequentially recorded single images look like a framed picture when examined individually. The term may also be used more generally as a noun or verb to refer to the edges of the image as seen in a camera viewfinder or projected on a screen. Thus, the camera operator can be said to keep a car in frame by panning with it as it speeds past. Overview When the moving picture is displayed, each frame is flashed on a screen for a short time (nowadays, usually 1/24, 1/25 or 1/30 of a second) and then immediately replaced by the next one. Persistence of vision blends the frames together, producing the illusion of a moving image. The frame is also sometimes used as a unit of time, so that a momentary event might be said to last six frames, the actual dur ...

Windows 9x
Windows 9x is a generic term referring to a series of Microsoft Windows computer operating systems produced from 1995 to 2000, which were based on the Windows 95 kernel and its underlying foundation of MS-DOS, both of which were updated in subsequent versions. The first version in the 9x series was Windows 95, which was succeeded by Windows 98 and then Windows Me, which was the third and last version of Windows on the 9x line, until the series was superseded by Windows XP. Windows 9x is predominantly known for its use in home desktops. In 1998, Windows made up 82% of operating system market share. Internal release versions for versions of Windows 9x are 4.x. The internal versions for Windows 95, 98, and Me are 4.0, 4.1, and 4.9, respectively. Previous MS-DOS-based versions of Windows used version numbers of 3.2 or lower. Windows NT, which was aimed at professional users such as networks and businesses, used a similar but separate version number between 3.1 and 4.0. All versio ...

Amiga
Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- or 32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. This includes the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprite (computer graphics), sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS. The Amiga 1000 was released in July 1985, but production problems kept it from becoming widely available until early 1986. The best-selling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The Amiga 3000 was introduced in 1990, followed by the Amiga 500 Plus, and Am ...

Sonic The Hedgehog 3
is a 1994 platform game developed and published by Sega for the Genesis. Like previous '' Sonic'' games, players traverse side-scrolling levels while collecting rings and defeating enemies. They control Sonic and Tails, who attempt to retrieve the Chaos Emeralds to stop the evil Doctor Robotnik from relaunching his space station, the Death Egg, after it crash-lands on a mysterious floating island. ''Sonic 3'' introduces Knuckles the Echidna, the island guardian, who lays traps for Sonic and Tails. Development began in January 1993 by Sega Technical Institute in California, shortly after the release of ''Sonic the Hedgehog 2''. It was initially developed as an isometric game similar to what would eventually become ''Sonic 3D Blast'' (1996), but became a conventional 2D platform game due to time constraints. ''Sonic 3'' was developed simultaneously with ''Sonic & Knuckles''; they were planned as a single game until time constraints and cartridge costs forced the developers to ...
