VRFrameData

The VRFrameData interface of the WebVR API represents all the information needed to render a single frame of a VR scene; constructed by getFrameData().

• pose Deprecated Read only
  • : The VRPose of the VRDisplay at the current timestamp.
• rightProjectionMatrix Deprecated Read only
  • : A Float32Array representing a 4x4 matrix that describes the projection to be used for the right eye’s rendering.

Specifications

This interface was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.

Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers. Read Meta’s Porting from WebVR to WebXR guide for more information.
