TypeVirtual reality and augmented reality API

OpenXR is an open, royalty-free standard for access to virtual reality and augmented reality platforms and devices.[1] It is developed by a working group managed by the Khronos Group consortium. OpenXR was announced by the Khronos Group on February 27 2017 during the GDC 2017.[2][3][4] A provisional version of the standard was released on March 18, 2019 to enable developers and implementers to provide feedback on it.[1]


The standard aims to eventually provide two components: an API aimed for application developers, and a device layer aimed for the virtual reality or augmented reality hardware, presenting an abstraction interface with the device itself.[5] The 0.90 provisional release contained an API, with the device layer being planned as a plugin interface for post-1.0 releases.[6][7]


In March 2017, the Khronos Group tentatively planned to release the first version of the API in late 2018.[8] The API was released in March 2019 as a provisional release, with a plugin device interface being planned for post-1.0 releases.[6][7]


The following companies are listed by Khronos as public supporters of OpenXR:[7]
