The Khronos Group has ratified and released the OpenXR 1.0 specification, along with publicly available implementations. OpenXR is a unifying, royalty-free open standard that provides high-performance, cross-platform access to virtual reality (VR) and augmented reality (AR) — collectively known as XR — platforms and devices. The new specification can be found on the Khronos website and via GitHub.
“The feedback from the community on the provisional specification released in March has been invaluable to getting us to this significant milestone,” says Brent Insko, OpenXR working group chair and lead XR architect at Intel. “Our work continues as we now finalize a comprehensive test suite, integrate key game engine support, and plan the next set of features to evolve a truly vibrant, cross-platform standard for XR platforms and devices. Now is the time for software developers to start putting OpenXR to work.”
After gathering feedback from the XR community during the public review of the provisional specification, improvements were made to the OpenXR input subsystem, game engine editor support and loader. With this 1.0 release, the working group will evolve the standard while maintaining full backward compatibility from this point onward, giving software developers and hardware vendors a solid foundation upon which to deliver portable user experiences.
OpenXR implementations are shipping this week, including the Monado OpenXR open source implementation from Collabora, the OpenXR runtime for Windows Mixed Reality headsets from Microsoft, an Oculus OpenXR implementation for Rift and Oculus Quest support. Epic Games also plans to release OpenXR 1.0 support in Unreal Engine.
