What are WebXR Device APIs?
WebXR is a group of standards being implemented by the browsers, which are used together to support rendering 3D scenes to hardware designed for Mixed Reality. Mixed Reality devices are presenting virtual worlds (virtual reality, or VR), or for adding graphical imagery to the real world, (augmented reality, or AR).
The WebXR Device API implements the core of the WebXR feature set, managing the selection of output devices, render the 3D scene to the chosen device at the appropriate frame rate, and manage input, such as controllers and hand interactions.
WebXR Device APIs are replacing the deprecated WebVR API. WebVR API was designed with only VR devices in mind. With the addition of new AR headsets and AR capable handheld devices, the WebVR API is deprecated in favor of WebXR Device APIs, that include AR Modules.
