In computing, WinG (pronounced ''Win Gee'') is an application programming interface that provides faster graphics performance on Windows 3.x operating environments, and was positioned as a way to help game developers more easily port their DOS games to Microsoft Windows. The WinG interface was also supported in Windows 95, Windows 98 and Windows NT 4.0, but Windows 98 Second Edition, Windows 2000 and later versions of the operating system did not support it. ==Background== The original Windows Graphics Device Interface (GDI) was designed with static images in mind, making its animation capabilities very limited. The GDI provides an interface to the graphics hardware that is device independent, that is, a program written using the GDI will work on all graphics and printer hardware, provided suitable Windows GDI drivers for the hardware are installed on the system. This means that graphics cannot be written to the physical framebuffer on the graphics hardware directly and must be written to a logical graphics "device context" (DC) provided by the GDI, which is then translated by the GDI and the device drivers to suit the target hardware device and is written to its physical frame buffer in an appropriate manner.〔 The major limitation of the GDI DCs was that they were write-only. Data, once written, could not be retrieved. This was because the contents of the DC was device dependent, and data read from it would make no sense to the programmer. In order to do animation using the GDI DC, all of the animation frames needed to be manipulated in system memory and then each frame needed to be copied into a GDI DC for display on the graphics device. This was a very slow process. Alex St. John, one of the creators of DirectX, said in a 2000 interview that, WinG first shipped on September 21, 1994. The success of WinG in enabling high-performance game development on Windows led directly to the inception of DirectX, which became the standard game development platform for Microsoft Windows, and later for the Xbox and Xbox 360 video game consoles. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WinG」の詳細全文を読む スポンサード リンク
