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.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

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().

Note: This interface was part of the old WebVR API. It has been superseded by the WebXR Device API.

Constructor

VRFrameData.leftViewMatrix Read only

A Float32Array representing a 4x4 matrix that describes the view transform to be used for the left eye's rendering.

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.

Examples

See VRDisplay.getFrameData() for example code.

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This interface was part of the old WebVR API that has been superseded by the WebXR Device API.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].
