Multiple Conformant OpenXR Implementations Ship Bringing to Life the Dream of Portable XR Applications

Khronos launches OpenXR 1.0 Adopters Program; Multiple implementations from Microsoft and Oculus already conformant; New advanced cross-vendor hand and eye tracking extensions; Minecraft, Blender, Chromium, and Firefox Reality embracing OpenXR.

Beaverton, OR - July 28, 2020 - Today, The Khronos® Group, an open consortium of industry-leading companies creating graphics and compute interoperability standards, announces multiple conformant implementations of OpenXR™ are shipping from Oculus and Microsoft, leveraging the newly opened OpenXR 1.0 Adopters Program and open source conformance tests. OpenXR is a royalty-free, open standard that provides direct access into Augmented Reality (AR) and Virtual Reality (VR)—collectively known as XR—runtimes across diverse platforms and devices. The OpenXR Adopter's Program enables consistent cross-vendor testing and reliable operation of OpenXR across multiple platforms and devices with OpenXR-conformant products published on the Khronos Conformant Product Registry.


Khronos members Microsoft and Facebook each have multiple conformant OpenXR-enabled devices showcasing how OpenXR enables portability across diverse platforms. PC-enabled virtual reality devices include Microsoft's Windows Mixed Reality and Oculus Rift headsets, enabling these HMDs, and any future OpenXR-compatible devices, to run the same application executable on Windows. In addition, Microsoft has released an OpenXR-conformant runtime for the HoloLens 2 headset, and Facebook has shipped a conformant runtime for the Android-based Oculus Quest, demonstrating OpenXR's flexibility to enable portable VR and AR applications across standalone and tethered XR devices—using different underlying operating systems.

"The Working Group has put tremendous effort into OpenXR conformance testing to create a truly reliable cross-platform API. We encourage OpenXR implementers to use the tests in their own development and consider contributing additional tests to help further reduce cross-vendor variability," said Brent Insko, working group chair, OpenXR Working Group and lead XR architect at Intel. "With the release of the conformance tests and official launch of the Adopters Program, widening availability of OpenXR across diverse devices, and expanding use in large open source projects, OpenXR is now ready for the next wave of adoption and deployment."

In addition, Valve has released a developer preview implementation of OpenXR 1.0 with new features on SteamVR expected to now appear through OpenXR, rather than OpenVR APIs. Similarly, Varjo's developer preview implementation of OpenXR enables the use of OpenXR applications with Varjo headsets. The Monado open source XR runtime founded by Collabora is also growing in compatibility and capability and is approaching conformance with OpenXR 1.0.

In parallel with finalizing the OpenXR 1.0 conformance tests, the OpenXR Working Group continues to push the API forward and announces today two OpenXR cross-vendor extensions for eye and hand tracking. These new extensions expand the range of advanced UI techniques that can be portably deployed through this cross-platform, cross-vendor API. In fact, Ultraleap has released a developer preview OpenXR integration for its hand tracking technology for Ultraleap tracking devices.

"This is another milestone for OpenXR, and Collabora is proud to have contributed to the development of the OpenXR specification as well as the open source conformance test suite," said Ryan Pavlik, specification editor, OpenXR Working Group, and principal software engineer at Collabora. "The Monado open source XR runtime project founded by Collabora is quickly approaching conformance. As specification editor, I commend the working group on their dedication to publishing and maintaining a high-quality standard and a comprehensive test suite. The suite is designed to ensure conformance to the specification and uniform application behavior across runtimes and environments, so the industry can deliver on the OpenXR promise of unifying reality."

OpenXR enables XR games and applications to target the widest range of hardware with maximum performance. Today, Microsoft is excited to announce that Minecraft's new RenderDragon rendering engine is building its desktop VR support using OpenXR! Further adding to OpenXR ecosystem momentum, several open source projects have also incorporated OpenXR. The free and open source 3D creation suite, Blender 2.83, has integrated OpenXR to deliver native VR scene inspection capabilities. Google recently released Chromium 81 with OpenXR as its default backend for WebXR, enabling Google Chrome and Microsoft Edge browsers to use any OpenXR-compatible hardware. Finally, Microsoft has released its OpenXR Samples for Mixed Reality Developers as open source, demonstrating how to use OpenXR to access the full capabilities of HoloLens 2. Firefox Reality also supports OpenXR browser for the HoloLens 2 platform.

"Khronos has done it again, bringing divergent industry organizations, technologies, and ambitions to a common ground that benefits all parties," said Dr. Jon Peddie of Jon Peddie Research. "OpenXR will not just save VR and AR-it will provide the launching pad to make all the promises, dreams, and potential be realized. An extraordinary body of work, the members are to be congratulated for their tireless effort. The industry is in your debt."

The OpenXR 1.0 Conformance Test Suite has been published as open source under the Apache 2.0 license on GitHub for continued public development and for use by any company as they implement the OpenXR API on their platform. Any implementers, whether or not a Khronos member, are welcome to become an OpenXR Adopter and submit conformance test results for working group review and approval in order to use the OpenXR trademark and gain patent protection under the Khronos Intellectual Property Framework.

Industry Support for OpenXR 1.0 Adopter's Program

"The latest release of the OpenXR 1.0 API conformance test suite is a significant step towards enabling XR content creation across multiple platforms on the same code base, allowing developers to focus more on their creative vision," said Ketan Shah, senior director of XR and wearables, client line of business, Arm. "At the same time, this release further advances Arm's performance optimization efforts in computer vision, machine learning, and graphics workloads on Arm-based solutions, enabling more immersive experiences on the untethered and lightweight head mounted devices of the future."

"As the XR industry marches towards maturity, Collabora is happy to see a growing number of major players adopt OpenXR," said Philippe Kalaf, CEO of Collabora.
