What is WebXR?

WebXR is a JavaScript application programming interface (API) that enables applications to interact with augmented reality and virtual reality devices, such as the HTC Vive, Oculus Rift, Google Cardboard or Open Source Virtual Reality (OSVR), in a web browser. — Wikipedia

WebXR API Design Principles:

➀ Detection of available virtual reality devices.

➁ Querying the device’s capabilities.

➂ Polling the device’s position and orientation.

➃ Displaying imagery on the device at the appropriate frame rate.
