The '''''Quake'' engine''' (part of '''[[id Tech 2]]''') is the [[game engine]] developed by [[id Software]] to power their 1996 video game ''[[Quake (video game)|Quake]]''. It featured [[true 3D]] [[real-time rendering]]. Since 1999, it has been licensed under the terms of [[GNU General Public License|GNU General Public License v2.0 or later]].

After release, the ''Quake'' engine was immediately [[fork (software development)|fork]]ed. Much of the engine remained in ''[[Quake II]]'' and ''[[Quake III Arena]]''. The ''Quake'' engine, like the [[Doom engine|''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.

Historically, the ''Quake'' engine has been treated as a separate engine from its successor, the [[Quake II engine|''Quake II'' engine]]. Although the codebases for ''Quake'' and ''Quake II'' were separate GPL releases,<ref>{{cite web |title=Quake engine GPL release |url=https://github.com/id-Software/Quake |access-date=May 24, 2020 |website=[[GitHub]]}}</ref><ref>{{cite web |title=id Tech 2 GPL release |url=https://github.com/id-Software/Quake-2 |access-date=May 24, 2020 |website=[[GitHub]]}}</ref> both engines are now considered variants of id Tech 2.<ref>{{cite web|url=http://www.idsoftware.com/business/idtech2/|title=id Tech 2 page|publisher=[[id Software]]|archive-url=https://web.archive.org/web/20080917045739/http://www.idsoftware.com/business/idtech2/|archive-date=2008-09-17}}</ref>

==History==
{{Further|Quake (video game)#Development}}

The ''Quake'' engine was developed from 1995 for the video game ''Quake'', released on June 22, 1996. [[John D. Carmack|John Carmack]] did most of the programming of the engine, with help from [[Michael Abrash]] in [[algorithm]]s and [[Assembly language|assembly]] [[optimization (computer science)|optimization]]. The [[Quake II engine]] (id Tech 2.5) was based on it.

[[John Romero]] initially conceived of ''Quake'' as an [[action game]] taking place in a fully [[3D computer graphics|3D polygon]] world, inspired by [[Sega AM2]]'s 3D [[fighting game]] ''[[Virtua Fighter]]''. ''Quake'' was also intended to feature ''Virtua Fighter''-influenced third-person [[Beat 'em up|melee combat]]. However, id Software considered it to be risky, and it would've taken longer to develop the engine. Because the project was taking too long, the third-person melee was eventually dropped.<ref name="nextgen">{{cite magazine|magazine=[[Next Generation (magazine)|Next Generation]]|issue=30|date=June 1997|pages=9–12|title=Does John Romero Still Enjoy Shooting People?|url=https://archive.org/stream/NextGeneration30Jun1997/Next_Generation_30_Jun_1997#page/n9/mode/2up}}</ref><ref>{{citation|title=[[Edge (magazine)|Edge]]|issue=45|date=May 1997|quote=My original idea was to do something like ''Virtua Fighter'' in a 3D world, with full-contact fighting, but you'd also be able to run through a world, and do the same stuff you do in ''Quake'', only when you got into these melees, the camera would pull out into a third-person perspective. It would've been great, but nobody else had faith in trying it. The project was taking too long, and everybody just wanted to fall back on the safe thing – the formula.}}</ref>

On December 21, 1999, John Carmack of id Software released the ''Quake'' engine [[source code]] on the Internet under the terms of GPL-2.0-or-later, allowing programmers to edit the engine and add new features. Programmers were soon releasing new versions of the engine on the net. Some of the most known engines are:
* '''[[GoldSrc]]''' – The first engine to be created by [[Valve Corporation|Valve]]. It was used in the [[Half-Life series|''Half-Life'' series]], and gave rise to the [[Source engine|Source]] and [[Source 2|Source 2 engines]].
