The process of defining a starting point and a direction, from which an imaginary line – the ray – is drawn. If this line intersects with an object with a collider (e.g. a bounding box that defines the outer perimeter of the object), the process returns information about this object (e.g. its position in world space) and the length of the line when it first collided. In VR this can for example be used to realize gaze interactions, finding out if a user points at an object and many things more.
The number of pixels that can be displayed on a display or HMD, usually shown as 'width x height', e.g. '1832 x 1920 per eye' for the Oculus Quest 2.
