XRRay.direction

The read-only direction property of the XRRay interface is a DOMPointReadOnly representing the ray's 3-dimensional directional vector, normalized to a unit vector with a length of 1.0.

Value

A DOMPointReadOnly object.

Examples

Using the direction property

The direction property contains the normalized ray’s 3-dimensional directional vector.

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}
