HMDVRDevice.setFieldOfView()

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This feature is obsolete.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 setFieldOfView() method of the HMDVRDevice interface can be used to set the field of view for one eye, or both eyes simultaneously.

Syntax

HMDVRDevice.setFieldOfView(leftFOV,rightFOV,zNear,zFar);

Parameters

leftFOV Optional
A VRFieldOfView object that defines the new field of view for the left eye. If not specified, the left eye field of view does not change.
rightFOV Optional
A VRFieldOfView object that defines the new field of view for the right eye. If not specified, the right eye field of view does not change.
zNear Optional
The distance from the eyes of the nearest point of the view. The closest things can be and still be in the view. If not specified, the default is used — 0.01.
zFar Optional
The distance from the eyes of the farthest point of the view. The furthest away things can be and still be in the view. If not specified, the default is used — 10000.0.

Returns

Void.

Examples

The following simple example shows a function that can be used to set a custom field of view with four specified degree values for up, right, down and left. The VRFieldOfView() constructor is used to create a VRFieldOfView object from the supplied values, which is then fed into the setFieldOfView() method (the default zNear and zFar values are always used, in this case.)

function setCustomFOV(up,right,down,left) {
  var testFOV = new VRFieldOfView(up,right,down,left);

  gHMD.setFieldOfView(testFOV,testFOV,0.01,10000.0);

  var lEye = gHMD.getEyeParameters('left');
  var rEye = gHMD.getEyeParameters('right');
  console.log(lEye.currentFieldOfView);
  console.log(rEye.currentFieldOfView);
}

Note: When testing, setting a weird/tiny field of view can really mess up your view. It is a good idea to grab the current field of view first (using VREyeParameters.currentFieldOfView) before making any drastic changes, so you can reset it afterwards if needed.
