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-ref-1[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.cite-ref-idtech2-2-0[2]

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.cite-ref-idtech2-2-1[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:

• 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-ref-3[3]
• id could release the source code to allow modifications while keeping the remainder of the engine proprietary.cite-ref-4[4]

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-ref-5[5]cite-ref-6[6]

id Software released the source code on December 22, 2001, under the terms of the GNU General Public License v2.0 or later.cite-ref-7[7]cite-ref-8[8]
