OpenXR is a work-in-progress standard that aims to unify the underlying connections between VR and AR hardware, game engines, and content, making for a more interoperable ecosystem.
This essentially means that any app created for one OpenXR headset should technically be able to run on an entirely different OpenXR headset with zero changes to the underlying code.
Oculus Rift and Rift S developers have already had preliminary access to OpenXR since late last year via that platform’s Public Test Channel, UploadVR notes.
Bringing Quest into the fold via prototype support for OpenXR potentially opens up that platform to a greater number of games, apps, and experiences, provided they can not only squeeze onto the standalone headset’s modest Snapdraon 835 chipset and make it past Oculus’ strict content selection process.
Facebook has published a developer blog post, noting that both the Oculus PC and Mobile SDKs will include the resources necessary to use the Prototype OpenXR API for native C/C++ development of Oculus Rift Platform apps and Android apps for Oculus Quest respectively.
