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 { ... }
