The Quake II engine (part of <a href="Id_Tech#id_Tech_2" title="Id Tech">id Tech 2</a>) is a <a href="Game_engine" title="Game engine">game engine</a> developed by <a href="Id_Software" title="Id Software">id Software</a> for use in their 1997 <a href="First-person_shooter" title="First-person shooter">first-person shooter</a> <a href="Quake_II" title="Quake II">Quake II</a>.<a href="#cite_note-1">[1]</a> It is the successor to the <a href="Quake_engine" title="Quake engine">Quake engine</a>. Since its release, the Quake II engine has been licensed for use in several other games.<a href="#cite_note-idtech2-2">[2]</a>

One of the engine's most notable features was out-of-the-box support for hardware-accelerated graphics, specifically <a href="OpenGL" title="OpenGL">OpenGL</a>, along with the traditional software renderer.<a href="#cite_note-idtech2-2">[2]</a> Another interesting feature was the subdivision of some of the components into <a href="Dynamic-link_library" title="Dynamic-link library">dynamic-link libraries</a>. 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:

<ul><li>Since they were compiled for specific platforms, instead of an <a href="Interpreter_(computing)" title="Interpreter (computing)">interpreter</a>, they could run faster than Quake's solution, which was to run the game logic (<a href="QuakeC" title="QuakeC">QuakeC</a>) in a limited interpreter.<a href="#cite_note-3">[3]</a></li>

<li>id could release the source code to allow modifications while keeping the remainder of the engine proprietary.<a href="#cite_note-4">[4]</a></li></ul>

The level format, as with previous id Software engines, used <a href="Binary_space_partitioning" title="Binary space partitioning">binary space partitioning</a>. The level environments were lit using <a href="Lightmap" title="Lightmap">lightmaps</a>, a method in which light data for each surface is precalculated (this time, via a <a href="Radiosity_(computer_graphics)" title="Radiosity (computer graphics)">radiosity</a> method) and stored as an image, which is then used to determine the lighting intensity each 3D model should receive, but not its direction.<a href="#cite_note-5">[5]</a><a href="#cite_note-6">[6]</a>

id Software released the source code on December 22, 2001, under the terms of the <a href="GNU_General_Public_License" title="GNU General Public License">GNU General Public License v2.0 or later</a>.<a href="#cite_note-7">[7]</a><a href="#cite_note-8">[8]</a>
