OpenXR is an open-source, royalty-free standard for access to virtual reality and augmented reality platforms and devices. [3] 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 GDC 2017. [4] [5] [6] A provisional version of the standard was released on March 18, 2019, to enable developers and implementers to provide feedback on it. [3] On July 29, 2019, OpenXR 1.0 was released to the public by Khronos Group at SIGGRAPH 2019. [7]

Contents

Reviewers of the 0.90 provisional release considered that the aim of OpenXR was to "Solve AR/VR Fragmentation". [8]

Architecture

The standard provides an API aimed for application developers targeting virtual reality or augmented reality hardware. This enables developers to build applications that will work across a wide variety of devices. [9]

The fundamental elements of this API are:

Implementations

The Khronos Group maintains the list of OpenXR-conformant platforms and products. [10]

Currently conformant OpenXR platforms are:

Game and rendering engine support

Support for OpenXR application development can be found in the following engines:

Browser support

Roadmap

After the release of OpenXR 1.0, progress will likely be driven through the development of extensions to the core API. [31] This can be seen in the subsequent release of extensions for support of hand tracking and eye gaze tracking. [32] As implementers and developers get more experience with the extensions, they could get integrated into the core OpenXR API in future releases.

Contributors

The following companies are listed by Khronos as public supporters of OpenXR: [33]

OpenVG is an API designed for hardware-accelerated 2D vector graphics. Its primary platforms are mobile phones, gaming & media consoles and consumer electronic devices. It was designed to help manufacturers create more attractive user interfaces by offloading computationally intensive graphics processing from the CPU onto a GPU to save energy. The OpenGL ES library provides similar functionality for 3D graphics. OpenVG is managed by the non-profit technology consortium Khronos Group.

OpenMAX, often shortened as "OMX", is a non-proprietary and royalty-free cross-platform set of C-language programming interfaces. It provides abstractions for routines that are especially useful for processing of audio, video, and still images. It is intended for low power and embedded system devices that need to efficiently process large amounts of multimedia data in predictable ways, such as video codecs, graphics libraries, and other functions for video, image, audio, voice and speech.

The Khronos Group, Inc. is an open, non-profit, member-driven consortium of 170 organizations developing, publishing and maintaining royalty-free interoperability standards for 3D graphics, virtual reality, augmented reality, parallel computation, vision acceleration and machine learning. The open standards and associated conformance tests enable software applications and middleware to effectively harness authoring and accelerated playback of dynamic media across a wide variety of platforms and devices. The group is based in Beaverton, Oregon.
