WebXR current position and beyond to the Recommendation

WebXR is a collection of APIs to interface with mixed reality consisted with Core API and feature specific modules, and enables you to provide 3D experience by managing the process of rendering 3D context, handing inputs from mixed reality hardware, and providing domain specific feature such as anchor or layers for projecting scenes. Since 2018, set of specifications are developed under the Immersive Web groups of the W3C, having a Candidate Recommendation status, and implemented in Chrome and various 3D headset devices.

WebXR APIs has been evolving to enable new hardware and sensing features, and to introduce new software features for both making widely used concepts into core specification and reducing pain points to use APIs in real space.

In this talk, following brief introduction and recent updates of WebXR specifications including bringing specifications to the W3C Recommendation, I will pick three emerging topics in WebXR field in detail.

First is 3D rendering processing, initially WebXR was built over WebGL to generate stream of 3D view, but direct use of GPU is desired and now under implementation. Second is spatial context, which enables you to connect physical space with virtual space, such as placing and handling virtual objects in physical space as if handling as physical objects over multiple mixed reality hardware, or shaing physical positions among devies. Thrid is model element to bring 3D assets as core media in the Web.
