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 leftBounds read-only property of the VRLayer interface (dictionary) defines the left texture bounds of the canvas whose contents will be presented by the VRDisplay.


var myVRLayer = { };
myVRLayer.leftBounds = [0.0, 0.0, 0.5, 1.0];


An array of four floating point values, which can take values from 0.0-1.0:

  • The left offset of the bounds.
  • The top offset of the bounds.
  • The width of the bounds.
  • The height of the bounds.

If leftBounds is not specified in the dictionary, the default value used is [0.0, 0.0, 0.5, 1.0].
