Today, we’re happy to announce that the WebXR Viewer app is available for download on iTunes. In our recent announcement of our Mixed Reality program, we talked about some explorations we were doing to extend WebVR to include AR and MR technology. In that post, we pointed at an iOS WebXR Viewer app we had developed to allow us to experiment with these ideas on top of Apple’s ARKit. While the app is open source, we wanted to let developers experiment with web-based AR without having to build the app themselves.
Code written with the webxr-polyfill runs in this app, as well as Google’s experimental WebARonARCore APK on Android. We are working on supporting other AR and VR browsers, including WebVR on desktop.
We’ve also been working on integrating the webxr-polyfill into the popular three.js graphics library and the A-Frame framework to make it easy for three.js and A-Frame developers to try out these ideas. We are actively working on these libraries and using them in our own projects; while they are works-in-progress, each contains some simple examples to help you get started with them. We welcome feedback and contributions!
We are not the only company interested in how WebVR could be extended to support AR and MR; for example, Google released a WebAR extension to WebVR with the WebARonARCore application mentioned above, and discussions on the WebVR standards documents has been lively with these issues.
As a result, the companies developing the WebVR API (including us) recently decided to rename the WebVR 2.0 proposal to the WebXR Device API and rename the WebVR Community Group to the Immersive Web Community Group, to reflect broad agreement that AR and VR devices should be exposed through a common API. The WebXR API we created was based on WebVR2.0; we will be aligning it with the WebXR Device API as is develops and continue using it to explore ideas for exposing additional AR concepts into WebXR.
