Web/API/VRFieldOfView

From Get docs

This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.


DeprecatedThis 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 VRFieldOfView interface of the WebVR API represents a field of view defined by 4 different degree values describing the view from a center point.

Properties

VRFieldOfView.upDegrees ' Read only
The number of degrees upwards that the field of view extends in.
VRFieldOfView.rightDegrees ' Read only
The number of degrees to the right that the field of view extends in.
VRFieldOfView.downDegrees ' Read only
The number of degrees downwards that the field of view extends in.
VRFieldOfView.leftDegrees ' Read only
The number of degrees to the left that the field of view extends in.

Examples

var info = document.querySelector('p');
var list = document.querySelector('ul');
var vrDisplay;

if(navigator.getVRDisplays) {
    reportFieldOfView();
} else {
  info.textContent = 'WebVR API not supported by this browser.'
}

function reportFieldOfView() {
  navigator.getVRDisplays().then(function(displays) {
    vrDisplay = displays[0];
    var lEye = vrDisplay.getEyeParameters('left');
    var rEye = vrDisplay.getEyeParameters('right');
    // lEye and rEye are VREyeParameters objects

    var lFOV = lEye.fieldOfView;
    var rFOV = rEye.fieldOfView;
    // lFOV and rFOV are VRFieldOfView objects

    var listitem1 = document.createElement('li');
    var listitem2 = document.createElement('li');

    listitem1.innerHTML = '<strong>Left eye parameters</strong>'
