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.
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.
Both the DirectX runtime and software development kit are available free of charge, but are proprietary and closed-source software. The DirectX runtime was originally redistributed by computer game developers along with their games, but later it was included in Microsoft Windows.
The latest release versions of Direct3D, 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 numeroase 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. |

DirectX functionality is provided in the form of Component Object Model interfaces, as well as a set of managed code interfaces.
The components comprising DirectX are
* DirectX Graphics, comprising two APIs:
o DirectDraw: for drawing 2D Graphics (raster graphics) (now mostly deprecated, although still in use by many)
o Direct3D (D3D): for drawing 3D graphics
* DirectInput: for interfacing with keyboards, mice, joysticks, or other game controllers (Not updated since 8 except for XInput, which is specifically for Xbox360 controllers. For keyboards and mice, WM INPUT is recommended instead.)
* DirectPlay: for networked communication of games (Along with DirectInput, was last updated in version 8. Now deprecated.)
* DirectSound: for the playback and recording of waveform sound
o DirectSound3D (DS3D): for the playback of 3D sounds.
* DirectMusic: for playback of soundtracks authored in DirectMusic Producer
* DirectX Media: comprising DirectAnimation for 2D web animation, DirectShow for multimedia playback and streaming media, DirectX Transform for web interactivity and Direct3D Retained Mode for higher level 3D graphics. DirectShow additionally contains DirectX plugins for audio signal processing and DirectX Video Acceleration for accelerated video playback.
* DirectX Media Objects: support for streaming objects such as encoders, decoder and effects
* DirectSetup: for the installation of DirectX components, not really an API |
