was originally registered to us back in the mid 90's. At that time DirectX was a new multimedia technology that Microsoft was introducing. We were working in DirectX and related technology and thought that it'd be a good location on the Internet. We never thought that Microsoft would later turn it into a brand name.

Microsoft DirectX is a collection of application programming interfaces for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with Direct, such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. DirectX, then, was the generic term for all of these Direct-something APIs, and that term became the name of the collection. Over the intervening years, some of these APIs have been deprecated and replaced, so that this naming convention is no longer absolute. In fact, the X has caught on to the point that it has replaced Direct as the common part in the names of new DirectX technologies, including XAct, XInput, and so forth. Additionally, when Microsoft decided to develop game consoles based on DirectX, the X stuck, leading to the name Xbox (and later Xbox 360).

Direct3D (the 3D graphics API within DirectX) is widely used in the development of computer games for Microsoft Windows, Microsoft Xbox, and Microsoft Xbox 360. Direct3D is also used by other software applications for visualization and graphics tasks, most notably among the engineering sector for CAD/CAM, because of its ability to quickly render high-quality 3D graphics using DirectX-compatible graphics hardware. As Direct3D is the most widely recognized API in DirectX, it is common to see the name DirectX used in place of Direct3D.

The interfaces that comprise DirectX include components for use by a running application (runtime components) as well as components for use by software developers at design time (the software development kit). The runtimes were originally redistributed by computer game developers along with their games, but are now included as built-in parts of Microsoft Windows. The SDK is available as a free download. While the runtimes are proprietary, closed-source software, source code is provided for most of the SDK samples.

The latest versions of Direct3D, namely, Direct3D 10 and Direct3D 9Ex, are exclusive to Windows Vista. This is because there were extensive changes in the Windows graphics architecture, and in particular the introduction of the Windows Display Driver Model. This redesign of the graphics infrastructure for Windows Vista supports virtualizing graphics hardware to multiple applications and services such as the Desktop Window Manager, in contrast to the exclusive access afforded to DirectX applications on Windows XP. Both Direct3D 9Ex and Direct3D 10 rely on the WDDM infrastructure and WDDM drivers.
