Unreal Engine 3 (UE3) is a computer game engine developed by Epic Games.
It is the third generation of Unreal Engine, designed for DirectX 9/10/11 personal computers, the Xbox 360,
PlayStation 3, Wii U, PlayStation Vita, Android and OpenGL-based operating systems such as iOS and Mac OS X.
Its renderer supports many advanced techniques including high dynamic range rendering (HDRR), per-pixel lighting,
and dynamic shadows, and builds upon the tools available in prior versions of the engine.
