* @typedef {object} StylusPickResult

* @property {boolean} intersects - <code>true</code> if there's a valid intersection, <code>false</code> if there isn't.
|
|
* @property {Uuid} objectID - The ID of the intersected object. <code>null</code> for invalid intersections.
|
|
* @property {number} distance - The distance to the intersection point from the stylus tip.

* @property {Vec3} surfaceNormal - The surface normal at the intersected point.
|
|
* @property {StylusTip} stylusTip - The stylus tip at the time of the result. Valid even if there is no intersection.
