The Quake II engine (part of id Tech 2) is a game engine developed by id Software for use in their 1997 first-person shooter Quake II.
{{cite web |url=http://www.joystiq.com/2011/08/09/id-software-looking-to-shorten-dev-cycles-stop-building-new-eng/ |title=id Software looking to shorten dev cycles, stop building new engines for every game |first=Christopher |last=Grant |date=August 9, 2011 |website=Joystiq |publisher=AOL |archive-url=https://web.archive.org/web/20110828160010/http://www.joystiq.com/2011/08/09/id-software-looking-to-shorten-dev-cycles-stop-building-new-eng/ |archive-date=August 28, 2011 }} It is the successor to the Quake engine. Since its release, the Quake II engine has been licensed for use in several other games.{{cite web |url=http://www.idsoftware.com/business/idtech2/ |title=Technology Licensing: id Tech 2 |access-date=September 17, 2008 |archive-url=https://web.archive.org/web/20091108191715/http://www.idsoftware.com/business/idtech2/ |archive-date=November 8, 2009 }}
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. 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:
- Since they were compiled for specific platforms, instead of an interpreter, they could run faster than Quake{{'}}s solution, which was to run the game logic (QuakeC) in a limited interpreter.{{cite web|url=https://fabiensanglard.net/quake2/quake2Polymorphism.php|title=Quake 2 Source Code Review 2/4|first=Fabien|last=Sanglard|date=September 16, 2011|website=fabiensanglard.net|access-date=July 29, 2023|quote=Dynamic linking provided numerous advantages: [...] Full native speed for mods, no need to rely on QuakeC and Quake Vitual machine.}}
- id could release the source code to allow modifications while keeping the remainder of the engine proprietary.{{cite web|url=https://fabiensanglard.net/quake2/quake2Polymorphism.php|title=Quake 2 Source Code Review 2/4|first=Fabien|last=Sanglard|date=September 16, 2011|website=fabiensanglard.net|access-date=July 29, 2023|quote=Dynamic linking provided numerous advantages: [...] More capabilities to mod makers, the entire game could be altered via game.dll.}}
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.{{cite web|url=https://www.pcgamer.com/the-making-of-quake-2/|title=The making of Quake 2|first=Rory|last=Milne|date=March 1, 2019|website=pcgamer.com|access-date=July 29, 2023|quote=We also had light bouncing—simulated radiosity—so every corner of the world had some lighting.}}{{cite web|url=https://fabiensanglard.net/quake2/quake2_software_renderer.php|title=Quake 2 Source Code Review 3/4|first=Fabien|last=Sanglard|date=September 16, 2011|website=fabiensanglard.net|access-date=July 29, 2023|quote=Contrary to Quake1, Quake2 used radiosity and colored light during the precalculation.}}

| quote=This is a great show of 3D prowess. Things like this, as well as the Narya 2D open source engine from ThreeRings really are starting to at least show Java can serve as a first-class gaming platform. More than that, just having seen all the… *cough* horrible code in games before, having things like Java's threading model, network and database support might really make it a BETTER platform for a lot of forthcoming games than C.
