The OpenXR 1.1 minor release comes out today, which moves some of the more commonly used extensions into core and it also marks a new Khronos Group commitment to a yearly release cycle. It's been nearly five years since the initial release of OpenXR 1.0 on July 29, 2019, and Khronos Group President Neil Trevett tells me that it's been one of the most successful open standards they've ever published, and I had a chance to catch up with Trevett and OpenXR working group chair Alfredo Muniz to talk about the range of conformant XR devices, engines, programs, what's happening with Apple and OpenXR, next steps for where they plan to take the standard in the future, and how you can get more involved either through their OpenXR Discord channel, OpenXR Forums, or OpenXR GitHub Issue Tracker.







Also, here's a link to the announcement slides for OpenXR 1.1, which have some really helpful overview information about how broadly OpenXR has been adopted, as well as a sneak peak at some of what is coming soon including "extending hand tracking, enhanced handling of spatial entities, expanded haptics support, controller render models (glTF), increased accessibility, and Metal (Mac OS) support."







I posted a thread on X / Twitter that highlights some of these slides from the OpenXR 1.1 announcement page.







Here's five previous interviews covering the evolution of OpenXR since 2015:









My 2015 interview with Neil Trevett with some preliminary thoughts about an open standard for VR







My 2016 interview with Neil Trevett announcing the formation of what would become OpenXR







My 2017 GDC conversation with Joe Ludwig marking the announcement of OpenXR.







My 2018 GDC conversation with OpenXR working group chair Nick Whiting with a first look at OpenXR.







My 2019 SIGGRAPH conversation with Neil Trevett marking the official OpenXR 1.0 release

I'm digging into my unpublished interview archives backlog to publish this conversation with Khronos Group President Neil Trevett marking the 1.0 release of OpenXR that happened during SIGGRAPH in July 2019. We talk about the intention of OpenXR as a specification, and I figured that it's worth looking back at the evolution of the specification as it has become quite a prominent open standard within the XR industry. Be sure to also see episodes #1382 that I just published from GDC 2018, #507 from GDC 2017, and #1385 with a current update on OpenXR 1.1.

OpenXR 1.1 is being released today, and so I'm digging into my archive of unpublished interviews to go back GDC 2018 when OpenXR working group chairman Nick Whiting presented some of the first information about the OpenXR specification, which wouldn't have it's initial release over a year later on July 29, 2019 (see episode #1384 for more on that). I'll also be publishing an update on OpenXR 1.1 in episode #1385, and so these next three episodes should provide a pretty comprehensive look at the evolution of OpenXR over the past 6+ years. Also be sure to check out episode #507 from GDC 2017 where I chat with Joe Ludwig about the initial announcement of OpenXR.

I interviewed The Golden Key co-directors Matthew Niederhauser & Marc Da Costa remotely during SXSW XR Experience 2024. See more context in the rough transcript below.
