In my Voices of VR interview with Ludwig, he talks about the OpenXR standardization process from Valve’s perspective and how they want to see VR become an open of a platform just as the PC has.
The OpenXR working group has just completed it’s exploratory process and there are still numerous open debates, and the Khronos Group is making this announcement of a name and logo at GDC in order to encourage more VR headset and peripheral companies to get involved in this standardization process.
But in order to know what APIs should be available for developers, then this standardization process requires the participation from as many VR companies as possible. Part of the announcement at GDC is to say that the working group has finished their preliminary exploration, and that they’re ready for more companies to get involved.
As to whether or not this OpenXR will mean that any VR headset will work with any VR software, that’s one of the theoretical technical goals but there are many constraints to making this happen. Ludwig said that while technically this could be made possible with OpenXR, there will still be a layer of business decisions around platform exclusives.
