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 {
