requestAnimationFrame() method of the
VRDisplay interface is a special implementation of
Window.requestAnimationFrame containing a callback function that will be called every time a new frame of the
VRDisplay presentation is rendered:
- When the
VRDisplayis not presenting a scene, this is functionally equivalent to
- When the VRDisplay is presenting, the callback is called at the native refresh rate of the
var handle = vrDisplayInstance.requestAnimationFrame(callback);
A callback function that will be called every time a new frame of the
VRDisplaypresentation is rendered.
A long representing the handle of the
requestAnimationFrame() call. This can then be passed to a
VRDisplay.cancelAnimationFrame() (en-US) call to unregister the callback.
