    VRFieldOfViewReadOnly.downDegrees

    This is an experimental technology
    Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

    The downDegrees read-only property of the VRFieldOfViewReadOnly interface returns the number of degrees downwards that the field of view extends in.

    Syntax

    var myDownDegrees = VRFieldOfViewReadOnly.downDegrees;

    Value

    A double.

    Examples

    You wouldn't access this property directly from VRFieldOfViewReadOnly; to access this property from VRFieldOfView, you could do something like this:

    var lEye = myHMDVRDevice.getEyeParameters('left');

lEye.recommendedFieldOfView.downDegrees
// returns something like 53.09438550469889

    • [1] The support in Chrome is currently experimental. To find information on Chrome's WebVR implementation status including supporting builds, check out Bringing VR to Chrome by Brandon Jones.
    • [2] The support for this feature is currently disabled by default in Firefox. To enable WebVR support in Firefox Nightly/Developer Edition, you can go to about:config and enable the dom.vr* prefs. A better option however is to install the WebVR Enabler Add-on, which does this for you and sets up other necessary parts of the environment.
    • [3] The dom.vr* prefs are enabled by default at this point, in Nightly/Aurora editions.
