![]() Within four months and with input from several hardware manufacturers, the team had developed the first set of application programming interfaces (APIs) which they presented at the 1995 Game Developers Conference. ![]() Most of the work by the three was done among other assigned projects starting near the end of 1994. Their rebellious nature led Brad Silverberg, the senior vice president of Microsoft's office products, to name the trio the "Beastie Boys". Management did not agree to the project as they were already writing off Windows as a gaming platform, but the three committed towards this project's development. It had initially used the radiation symbol as its logo but Microsoft asked the team to change the logo. The project was codenamed the Manhattan Project, like the World War II project of the same name, and the idea was to displace the Japanese-developed video game consoles with personal computers running Microsoft's operating system. John recognized the resistances for game development under Windows would be a limitation, and recruited two additional engineers, Craig Eisler and Eric Engstrom, to develop a better solution to get more programmers to develop games for Windows. Due to numerous incompatible graphics drivers from new Compaq computers that were not tested with the WinG interface which came bundled with the game, it crashed so frequently on many desktop systems that parents had flooded Disney's call-in help lines. There were also strong fears of compatibility a notable case of this was from Disney's Animated Storybook: The Lion King which was based on the WinG programming interface. ![]() John had been in discussions with various game developers asking how likely they would be to bring their MS-DOS games to Windows 95, and found the responses mostly negative programmers had found that the Windows environment did not provide the necessary features which were available under MS-DOS using BIOS routines or direct hardware access. An important factor in the value consumers would place on it was the programs that would be able to run on it. In late 1994, Microsoft was ready to release Windows 95, its next operating system. Starting with the release of Windows 8 Developer Preview, DirectX SDK has been integrated into Windows SDK. While the runtimes are proprietary, closed-source software, source code is provided for most of the SDK samples. Windows 98 and Windows NT 4.0 both shipped with DirectX, as has every version of Windows released since. Windows 95 did not launch with DirectX, but DirectX was included with Windows 95 OEM Service Release 2. Originally, the runtimes were only installed by games or explicitly by the user. ![]() The DirectX software development kit (SDK) consists of runtime libraries in redistributable binary form, along with accompanying documentation and headers for use in coding. As Direct3D is the most widely publicized component of DirectX, it is common to see the names "DirectX" and "Direct3D" used interchangeably. Direct3D is also used by other software applications for visualization and graphics tasks such as CAD/CAM engineering. The X initial has been carried forward in the naming of APIs designed for the Xbox such as XInput and the Cross-platform Audio Creation Tool (XACT), while the DirectX pattern has been continued for Windows APIs such as Direct2D and DirectWrite.ĭirect3D (the 3D graphics API within DirectX) is widely used in the development of video games for Microsoft Windows and the Xbox line of consoles. When Microsoft later set out to develop a gaming console, the X was used as the basis of the name Xbox to indicate that the console was based on DirectX technology. ![]() The name DirectX was coined as a shorthand term for all of these APIs (the X standing in for the particular API names) and soon became the name of the collection. Originally, the names of these APIs all began with "Direct", such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Microsoft Windows, Windows Phone 8, Dreamcast, Xbox, Xbox 360, Xbox One, Xbox Series X and Series S, Linux (Gallium Nine) (DirectX 12 only, Exclusive to Windows Subsystem for Linux), ![]()
