First announced only for OS X, at Apple’s Worldwide Developers Conference in 2005, it has since been extended to target more than fifteen platforms.〔(【引用サイトリンク】url=http://unity3d.com/unity/multiplatform/ )〕 It is now the default software development kit (SDK) for the Wii U.〔 Five versions of Unity have been released. At the 2006 WWDC trade show, Apple, Inc. named Unity as the runner up for its Best Use of Mac OS X Graphics category. ==Overview== With an emphasis on portability, the engine targets the following APIs: Direct3D on Windows and Xbox 360; OpenGL on Mac and Windows; OpenGL ES on Android and iOS; and proprietary APIs on video game consoles. Unity allows specification of texture compression and resolution settings for each platform the game engine supports,〔 and provides support for bump mapping, reflection mapping, parallax mapping, screen space ambient occlusion (SSAO), dynamic shadows using shadow maps, render-to-texture and full-screen post-processing effects.〔(【引用サイトリンク】url=http://docs.unity3d.com/Documentation/Manual/DirectX11.html )〕 Unity's graphics engine's platform diversity can provide a shader with multiple variants and a declarative fallback specification, allowing Unity to detect the best variant for the current video hardware; and if none are compatible, fall back to an alternative shader that may sacrifice features for performance.〔(【引用サイトリンク】url=http://docs.unity3d.com/Documentation/Manual/Shaders.html )〕 Unity is notable for its ability to target games to multiple platforms. Within a project, developers have control over delivery to mobile devices, web browsers, desktops, and consoles.〔〔(【引用サイトリンク】url=http://unity3d.com/unity/multiplatform/ )〕 Supported platforms include BlackBerry 10, Windows Phone 8, Windows, OS X, Android, iOS, Unity Web Player (including Facebook), PlayStation 3, PlayStation 4, PlayStation Vita, Xbox 360, Xbox One, Wii U, Nintendo 3DS line and Wii. It includes an asset server and Nvidia's PhysX physics engine. Unity Web Player is a browser plugin that is supported in Windows and OS X only. Unity is the default software development kit (SDK) for Nintendo's Wii U video game console platform, with a free copy included by Nintendo with each Wii U developer license. Unity Technologies calls this bundling of a third-party SDK an "industry first".〔 In Japan, Unity has a moe mascot character named , real name (voiced by Asuka Kakumoto). The company allows the use of Unity-chan and related characters for use in secondary projects under certain licenses.〔(【引用サイトリンク】title=DATA DOWNLOAD-Guideline - UNITY-CHAN!
