Unifying Reality

OpenXR is a royalty-free, open standard that provides high-performance access to Augmented Reality (AR) and Virtual Reality (VR)—collectively known as XR—platforms and devices.

OpenXR 1.0 is Here!

The OpenXR 1.0 specification was released on July 29th 2019

OpenXR Reaching for the Moon

“OpenXR seeks to simplify AR/VR software development, enabling applications to reach a wider array of hardware platforms without having to port or re-write their code and subsequently allowing platform vendors supporting OpenXR access to more applications. With the release of the OpenXR 1.0 specification, AR/VR developers can now create true cross-platform XR experiences.”

Solving XR fragmentation

Without a cross-platform standard, VR and AR applications and engines must use each platform’s proprietary APIs. New input devices need customized driver integration.

“The time to embrace OpenXR is now. In the year since the industry came together to publish the OpenXR 1.0 spec and demonstrated working bits at SIGGRAPH 2019, so much progress has happened. Seeing the core platforms in our industry getting behind the standard and shipping real, conformant implementations, as well as coming together to push the spec forward with cross-vendor extensions for critical features like hand tracking and eye tracking, is singularly awesome. As for the Mixed Reality platform we build at Microsoft, the base specification plus these extensions allow us to ship a conformant OpenXR 1.0 implementation to all Windows Mixed Reality and HoloLens 2 users that provides complete access to the functionality of the products. No compromise. And on the content side, the adoption of OpenXR in Minecraft’s desktop VR product further reinforces Microsoft’s commitment to the success of OpenXR.”
