Id Techid Tech is a series of separate game engines designed and developed by id Software. Prior to the presentation of the id Tech 5-based game Rage in 2011, the engines lacked official designation and as such were simply referred to as the Doom and Quake engines, from the name of the main game series the engines had been developed for. "id Tech" has been released as free software under the GNU General Public License. id Tech versions 0 to 3 were released under GPL-2.0-or-later. id Tech versions 3.5 to 4.
First-person shooter engineA first-person shooter engine is a video game engine specialized for simulating 3D environments for use in a first-person shooter video game. First-person refers to the view where the players see the world from the eyes of their characters. Shooter refers to games which revolve primarily around wielding firearms and killing other entities in the game world, either non-player characters or other players. The development of the FPS graphic engines is characterized by a steady increase in technologies, with some breakthroughs.
Quake engineThe Quake engine is the game engine developed by id Software to power their 1996 video game Quake. It featured true 3D real-time rendering and is now licensed under the terms of GNU General Public License v2.0 or later. After release, the Quake engine immediately forked. Much of the engine remained in Quake II and Quake III Arena. The Quake engine, like the Doom engine, used binary space partitioning (BSP) to optimise the world rendering. The Quake engine also used Gouraud shading for moving objects, and a static lightmap for non-moving objects.
Id Softwareid Software LLC (ɪd) 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 at the time.
Video game moddingVideo game modding (short for "modification") is the process of alteration by players or fans of one or more aspects of a video game, such as how it looks or behaves, and is a sub-discipline of general modding. Mods may range from small changes and tweaks to complete overhauls, and can extend the replay value and interest of the game. Modding a game can also be understood as the act of seeking and installing mods to the player's game, but the act of tweaking pre-existing settings and preferences is not truly modding.
Game engineA game engine is a software framework primarily designed for the development of video games and generally includes relevant libraries and support programs such as a level editor. The "engine" terminology is similar to the term "software engine" used in the software industry. The game engine can also refer to the development software utilizing this framework, typically offering a suite of tools and features for developing games. Developers can use game engines to construct games for video game consoles and other types of computers.
