A collection of APIs for handling multimedia tasks in game programming and video on Microsoft platforms.
DirectX is a collection of application programming interfaces (APIs) developed by Microsoft for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. First released in 1995, DirectX is composed of multiple APIs:
- Direct3D for rendering 2D and 3D graphics.
- DirectSound for the playback and recording of audio.
- DirectInput for handling input from keyboards, mice, joysticks, and other gaming devices.
- DirectPlay for communicating over local networks and the Internet in multiplayer games.
Since the introduction of DirectX, Microsoft has updated it many times to support new features and hardware capabilities. DirectX 12, released in 2015, added better support for multi-threading and multi-core processors. Using DirectX, game developers can optimize performance and take advantage of powerful graphics hardware, such as GPUs produced by Nvidia and AMD.
DirectX provides a common set of interfaces that game developers can rely on to access different features. It abstracts away many complex low-level details of rendering, audio, and input. This makes it much easier to program real-time graphics applications on Microsoft Windows.
