Web/API/VREyeParameters/recommendedFieldOfView

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

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

The recommendedFieldOfView read-only property of the VREyeParameters interface describes the recommended field of view for the current eye — ideally based on user calibration.

Syntax

var recFOV = myEyeParameters.recommendedFieldOfView;

Value

A VRFieldOfView object.

Examples

The following example is taken from the Mozilla VR Team's threejs-vr-boilerplate code — to be precise, the VREffect.js file. Early on in the code the HMDVRDevice.getEyeParameters method is used to access information about each eye — VREyeParameters.eyeTranslation and VREyeParameters.recommendedFieldOfView — which are used for rendering calulations later on.

if ( vrHMD.getEyeParameters !== undefined ) {

    var eyeParamsL = vrHMD.getEyeParameters( 'left' );
    var eyeParamsR = vrHMD.getEyeParameters( 'right' );

    eyeTranslationL = eyeParamsL.eyeTranslation;
    eyeTranslationR = eyeParamsR.eyeTranslation;
    eyeFOVL = eyeParamsL.recommendedFieldOfView;
    eyeFOVR = eyeParamsR.recommendedFieldOfView;

} else {

  ...

}
