DirectX

DirectX is a collection of APIs developed to facilitate complex tasks related to multimedia, especially video and game programming, on the Microsoft Windows platform.
DirectX consists of the following APIs:
- Direct3D: used for processing and programming graphics in three dimensions (one of the most used features of DirectX).
- Direct Graphics: to draw images in two dimensions (planes), and to represent images in three dimensions.
- DirectInput: to process keyboard data, mouse, joystick and other game controls.
- DirectPlay: for network communications.
- DirectSound: for playback and recording of wave sounds.
- DirectMusic: for the reproduction of composite musical tracks with DirectMusic Producer.
- DirectShow: to play audio and video with network transparency.
- DirectSetup: for the installation of DirectX components.
- DirectCompute: language and special instructions for handling hundreds or thousands of processing threads, special for mass core processors.
- DirectML: for artificial intelligence processing and more features that will be incorporated in the 2019 Spring Update for Windows 10.
- DirectX Raytracing (DXR): is a feature for Microsoft DirectX that allows real-time lightning hardware, a significant advance in computer graphics first seen at the consumer level in GPU, such as the Nvidia GeForce 20 series announced in 2018. DXR will not be launched as part of a new DirectX version, but as a DirectX 12-compatible extension.
The Windows 10 October 2018 Update includes the public version of DirectX Raytracing. Despite being developed exclusively for the Windows platform, an open source implementation of its API for Unix systems (particularly Linux) and X Window System is being developed by the WineHQ project, of which there is a proprietary fork, Cedega, developed by the software company «Transgaming» and oriented to the execution of games developed for Windows under Unix systems.

Notes:
- DirectX 4 was never released. Raymond Chen explains in his book, The Old New Thingthat after DirectX 3 was released, Microsoft began to develop versions 4 and 5 at the same time. Version 4 was to be a version with small improvements, while version 5 would be a more substantial release. But due to the lack of interest on the part of the video game developers regarding the improvements set for DirectX 4, it was made to one side, and the corpus of documents that had already recognized the two new versions, resulted in the choice of Microsoft not to choose to reuse version 4 to describe the features envisaged for version 5.
- Some applications and games require DirectX 9. However, your team includes a newer version of DirectX. If you install and run an app or game that requires DirectX 9, you may receive an error message similar to "The program cannot be started because d3dx9_35.dll is missing from the computer. Try to reinstall the program to correct this problem". To correct this problem you must install DirectX 9 in its latest version of June 2010.
DirectX 12
DirectX 12 was officially announced by Microsoft at GDC on March 18, 2014.
