Providing Layer and Extension Development for OpenXR

If your company needs help with developing API layers, drafting extensions, developing runtimes, or testing runtime implementations and applications for the OpenXR API, LunarG can assist you. OpenXR is a new open-source software standard developed by the Khronos® community that provides developers with high-performance access to augmented reality (AR) and virtual reality (VR)—collectively known as XR—platforms and devices. The new OpenXR standard provides the specification to create develop-once applications and games that can run across multiple hardware platforms with minimal modifications.

OpenXR is the interface between an application and an in-process or out-of-process “XR runtime.” The runtime handles such functionality as frame composition, view re-projection, headset management, and head and hand tracking information.

Optionally, a runtime may support device layer plugins that allow access to a variety of hardware across a commonly defined interface.

Benefits of OpenXR

Promotes adoption of AR/VR by helping to eliminate confusion and fragmentation of different companies developing their own APIs

Enables games and other applications written to the OpenXR standard to work across a variety of hardware platforms without having to port or re-write code or develop proprietary SDKs

Greatly increases developer productivity; opens AR/VR solution providers to larger revenue options with multi-platform support

Provides platform vendors that support OpenXR with access to more applications
