The Quake II engine is a game engine developed by id Software for use in their 1997 first-person shooter Quake II . [1] It is the successor to the Quake engine. Since its release, the Quake II engine has been licensed for use in several other games. [2]

Contents

One of the engine's most notable features was out-of-the-box support for hardware-accelerated graphics, specifically OpenGL, along with the traditional software renderer. [2] Another interesting feature was the subdivision of some of the components into dynamic-link libraries. This allowed both software and OpenGL renderers, which were selected by loading and unloading separate libraries. Libraries were also used for the game logic, with consequences including:

The level format, as with previous id Software engines, used binary space partitioning. The level environments were lit using lightmaps, a method in which light data for each surface is precalculated (this time, via a radiosity method) and stored as an image, which is then used to determine the lighting intensity each 3D model should receive, but not its direction. [5] [6]

id Software released the source code on December 22, 2001, under the terms of the GNU General Public License v2.0 or later. [7]

The operating system Linux can be used for playing video games. Because many games are not natively supported for the Linux kernel, various software has been made to run Windows games, such as Wine, Cedega, and Proton, and managers such as Lutris and PlayOnLinux. The Linux gaming community has a presence on the internet with users who attempt to run games that are normally not supported on Linux.

The engine was first demonstrated at the WWDC 2007 by John D. Carmack on an eight-core computer; however, the demo used only a single core with single-threaded OpenGL implementation running on a 512 MB 7000 class Quadro video card. id Tech 5 was first used in the video game Rage, followed by Wolfenstein: The New Order, The Evil Within and Wolfenstein: The Old Blood. It was followed up by id Tech 6.

id Tech Series of video game engines

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 4.5 were released under GPL-3.0-or-later. id Tech 5 to 7 are proprietary, with id Tech 7 currently being the latest utilized engine.
