VRFrameData

Deprecated

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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

VRFrameData.pose Read only
The VRPose of the VRDisplay at the current VRFrameData.timestamp.
VRFrameData.rightProjectionMatrix Read only
A Float32Array representing a 4x4 matrix that describes the projection to be used for the right eye’s rendering.
VRFrameData.rightViewMatrix Read only
A Float32Array representing a 4x4 matrix that describes the view transform 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This interface was part of the old WebVR API that has been superseded by the WebXR Device API.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 [1].
