VRFrameData.rightProjectionMatrix

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 rightProjectionMatrix read-only property of the VRFrameData interface returns a Float32Array representing a 4x4 matrix that describes the projection to be used for the right eye’s rendering.

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 It has been superseded by the WebXR Device API.

This value may be passed directly to WebGL’s uniformMatrix4fv function.

Warning: It is highly recommended that applications use this matrix without modification. Failure to use this projection matrix when rendering may cause the presented frame to be distorted or badly aligned, resulting in varying degrees of user discomfort.

Syntax

var myRPM = vrFrameDataInstance.rightProjectionMatrix;

Value

A Float32Array object.

Examples

See VRDisplay.getFrameData() for example code.

Specifications

This property was part of the old WebVR API that has been superseded by the WebXR Device API.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