Khronos Releases OpenXR 0.90 Provisional Specification for High-Performance Access to AR and VR Platforms and Devices
The OpenXR 0.90 provisional release specifies a cross-platform Application Programming Interface (API) enabling XR hardware platform vendors to expose the functionality of their runtime systems. By accessing a common set of objects and functions corresponding to application lifecycle, rendering, tracking, frame timing, and input, which are frustratingly different across existing vendor-specific APIs, software developers can run their applications across multiple XR systems with minimal porting effort—significantly reducing industry fragmentation.
Many of these implementations are becoming available for developers to evaluate including the ‘Monado’ OpenXR open source implementation from Collabora and the OpenXR runtime for Windows Mixed Reality headsets from Microsoft shipping today. Additionally, the Unreal Engine from Epic plans to continue to support OpenXR.
The group has a wide array of supporters from across the hardware, software, and game industries. Among the supporters are Intel, Advanced Micro Devices, Nvidia, Microsoft, HTC, Samsung, Qualcomm, Valve, Oculus, Google, Unity, and others.
Notably absent is Apple.
