VRDisplay.requestAnimationFrame()

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 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 VRDisplay is not presenting a scene, this is functionally equivalent to Window.requestAnimationFrame.
When the VRDisplay is presenting, the callback is called at the native refresh rate of the VRDisplay.

Syntax

var handle = vrDisplayInstance.requestAnimationFrame(callback);

Parameters

callback: A callback function that will be called every time a new frame of the VRDisplay presentation is rendered.

Return value

A long representing the handle of the requestAnimationFrame() call. This can then be passed to a VRDisplay.cancelAnimationFrame() call to unregister the callback.

Examples

TBD.
