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 {

  ...

}
