Id Software
id Software LLC () is an American video game developer based in Richardson, Texas. It was founded on February 1, 1991, by four members of the computer company Softdisk: programmers John Carmack and John Romero, game designer Tom Hall, and artist Adrian Carmack. id Software made important technological developments in video game technologies for the PC (running MS-DOS and Windows), including work done for the '' Wolfenstein'', ''Doom'', and '' Quake'' franchises. id's work was particularly important in 3D computer graphics technology and in game engines that are used throughout the video game industry. The company was involved in the creation of the first-person shooter (FPS) genre: ''Wolfenstein 3D'' is often considered to be the first true FPS; ''Doom'' is a game that popularized the genre and PC gaming in general; and '' Quake'' was id's first true 3D FPS. On June 24, 2009, ZeniMax Media acquired the company. In 2015, they opened a second studio in Frankfurt, Germany. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Game Console
A video game console is an electronic device that Input/output, outputs a video signal or image to display a video game that can be played with a game controller. These may be home video game console, home consoles, which are generally placed in a permanent location connected to a television or other display devices and controlled with a separate game controller, or handheld game console, handheld consoles, which include their own display unit and controller functions built into the unit and which can be played anywhere. Hybrid consoles combine elements of both home and handheld consoles. Video game consoles are a specialized form of a home computer geared towards video game playing, designed with affordability and accessibility to the general public in mind, but lacking in raw computing power and customization. Simplicity is achieved in part through the use of game cartridges or other simplified methods of distribution, easing the effort of launching a game. However, this leads ...

IBM PC Compatible
IBM PC compatible computers are similar to the original IBM PC, XT, and AT, all from computer giant IBM, that are able to use the same software and expansion cards. Such computers were referred to as PC clones, IBM clones or IBM PC clones. The term "IBM PC compatible" is now a historical description only, since IBM no longer sells personal computers after it sold its personal computer division in 2005 to Chinese technology company Lenovo. The designation "PC", as used in much of personal computer history, has not meant "personal computer" generally, but rather an x86 computer capable of running the same software that a contemporary IBM PC could. The term was initially in contrast to the variety of home computer systems available in the early 1980s, such as the Apple II, TRS-80, and Commodore 64. Later, the term was primarily used in contrast to Apple's Macintosh computers. These "clones" duplicated almost all the significant features of the original IBM PC architectures. ...

Adaptive Tile Refresh
Adaptive tile refresh is a computer graphics technique for side-scrolling video games. It was most famously used by id Software's John Carmack in games such as '' Commander Keen'' to compensate for the poor graphics performance of PCs in the early 1990s. Its principal innovation is a novel use of several EGA hardware features to perform the scrolling in hardware. The technique is named for its other aspect, the tracking of moved graphical elements in order to minimize the amount of redrawing required in every frame. Together, the combination saves the processing time that would be otherwise required for redrawing the entire screen. Carmack designed the software engine based on a scrolling display for large images from the 1970s. Because CGA (the previous generation of PC graphics hardware) lacks features for scrolling in hardware, scrolling previously had to be done in software, by redrawing the entire screen for every frame – a task that PCs of the time lacked the performance ...

Shareware
Shareware is a type of proprietary software that is initially shared by the owner for trial use at little or no cost. Often the software has limited functionality or incomplete documentation until the user sends payment to the software developer. Shareware is often offered as a download from a website or on a compact disc included with a magazine. Shareware differs from freeware, which is fully-featured software distributed at no cost to the user but without source code being made available; and free and open-source software, in which the source code is freely available for anyone to inspect and alter. There are many types of shareware and, while they may not require an initial up-front payment, many are intended to generate revenue in one way or another. Some limit use to personal non-commercial purposes only, with purchase of a license required for use in a business enterprise. The software itself may be time-limited, or it may remind the user that payment would be appreciated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pogo Stick
A pogo stick is a device for jumping off the ground in a standing position, through the aid of a spring, or new high performance technologies, often used as a toy, exercise equipment or extreme sports instrument. It led to an extreme sport named extreme pogo or "Xpogo". It consists of a pole with a handle at the top and footrests near the bottom, and a spring located somewhere along the pole. The spring joins two sections of the pole, which extends below the footpads. The jumper places their feet on the footpads while balancing on the pole, then jumps up or down with a bending action of the knees to add or subtract energy in the spring. When the spring is at full compression or extension, the jumper is lifted by the recoil of the spring, being launched several inches or feet into the air. This process is repeated to maintain a periodic bounce. The pogo stick can be steered by shifting one's weight off the centerline of the spring in the desired horizontal direction thus produc ...

Raygun
A raygun is a science-fiction directed-energy weapon that releases energy, usually with destructive effect.Jeff Prucher, '' Brave New Words: The Oxford Dictionary of Science Fiction,'' Oxford University Press, 2007, page 162 They have various alternate names: ray gun, death ray, beam gun, blaster, laser gun, laser pistol, phaser, zap gun, etc. In most stories, when activated, a raygun emits a ray, typically visible, usually lethal if it hits a human target, often destructive if it hits mechanical objects, with properties and other effects unspecified or varying. Real-world analogues are directed-energy weapons or electrolasers: electroshock weapons which send current along an electrically conductive laser-induced plasma channel. History A very early example of a raygun is the Heat-Ray featured in H. G. Wells' novel ''The War of the Worlds'' (1898).Van Riper, op. cit., p. 46. Science fiction during the 1920s described death rays. Early science fiction often described or depic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platform Game
A platform game (often simplified as platformer and sometimes called a jump 'n' run game) is a sub-genre of action video games in which the core objective is to move the player character between points in an environment. Platform games are characterized by levels that consist of uneven terrain and suspended platforms of varying height that require jumping and climbing to traverse. Other acrobatic maneuvers may factor into the gameplay, such as swinging from vines or grappling hooks, jumping off walls, air dashing, gliding through the air, being shot from cannons, or bouncing from springboards or trampolines. Games where jumping is automated completely, such as 3D games in ''The Legend of Zelda'' series, fall outside of the genre. The genre started with the 1980 arcade video game, '' Space Panic'', which includes ladders, but not jumping. '' Donkey Kong'', released in 1981, established a template for what were initially called "climbing games." ''Donkey Kong'' inspired many clon ...
