Using the direction property
The direction property contains the normalized ray's 3-dimensional directional vector.
js
let origin = { x: 10.0, y: 10.0, z: 10.0, w: 1.0 };
let direction = { x: 10.0, y: 0.0, z: 0.0, w: 0.0 };
let ray = new XRRay(origin, direction);
ray.direction;
// returns DOMPointReadOnly {x : 1.0, y : 0.0, z : 0.0, w : 0.0}
