VRPose.hasOrientation

The hasOrientation read-only property of the VRPositionState interface returns a boolean indicating whether the VRPositionState.orientation property is valid (i.e. if the hardware is currently registering a valid orientation). If it is false, the orientation property will return null.

VRPose.hasPosition

The hasPosition read-only property of the VRPositionState interface returns a boolean indicating whether the VRPositionState.position property is valid (i.e. if the hardware is currently registering a valid position). If it is false, the position property will return null.

WebVTT

WebVTT is a format for displaying timed text tracks (e.g. subtitles or captions) with the <track> element. The primary purpose of WebVTT files is to add text overlays to a <video>. WebVTT is a text based format, which must be encoded in UTF-8 format. Where you can use spaces you can also use tabs.
