requestAnimationFrame method
The requestAnimationFrame method contains a callback function that will be called every time a frame of the VRDisplay presentation is rendered.
Syntax
var retval = VRDisplay.requestAnimationFrame(callback);
Parameters
- callback
Type: FrameRequestCallback
Return value
Type: Integer
The handle of the requestAnimationFrame. Passing this to cancelAnimationFrame will unregister the callback.
Remarks
If the VRDisplay isn't presenting, the requestAnimationFrame property is functionally equivalent to Window.requestAnimationFrame.
