HMDVRDevice.getEyeParameters

Obsolete
This feature is obsolete.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 technology
Check the Browser compatibility table carefully before using this in production.

The getEyeParameters() method of the HMDVRDevice interface returns current parameters for the eye specified as its argument ("left" or "right") — stored in a VREyeParameters object.

This includes field of view information, and more.

Syntax

var myLeftEye = HMDVRDevice.getEyeParameters('left');

Parameters

whichEye: A DOMString representing the eye you want to return information about. The value can be left or right.

Returns

A VREyeParameters 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 getEyeParameters() method is used to access information about each eye, which is then 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 {
  ...
}
