The read-only XRRigidTransform property orientation is a DOMPointReadOnly containing a normalized quaternion (also called a unit quaternion or versor) specifying the rotational component of the transform represented by the object. If you specify a quaternion whose length is not exactly 1.0 meters, it will be normalized for you.


let orientation = xrRigidTransform.orientation;


A DOMPointReadOnly object which contains a unit quaternion providing the orientation component of the transform. As a unit quaternion, the length of the returned quaternion is always 1.0 meters.


To create a reference space which is oriented to look straight up, positioned 2 meters off of ground level:

xrReferenceSpace = refSpace.getOffsetReferenceSpace(
  new XRRigidTransform({y: -2}, {x: 0.0, y: 1.0, z: 0.0, w: 1.0});

The unit quaternion specified here is [0.0, 1.0, 0.0, 1.0] to indicate that the object should be facing directly along the y axis.
