Ray vs vector

WebJan 22, 2014 · A point is a location in a coordinate system, that is a location defined relatively to an origin. If you were to move the origin without moving the point, then the coordinates of the point would change. A vector is a more general object. No matter where you draw a vector v → on a plane, it is still the same. WebJun 19, 2024 · 1 Answer. Vector and ray are symbolized the same way: a line segment with an arrow on one end but they are very different things. A vector has a direction and a magnitude (for example, 5 km south-east). A ray has just a direction and a starting point, …

First, a refresher on vectors (and subsequently, rays). A vector is nothing more than a line segment in space, with a head and a tail. For example, you could have the 2D vector \(\vec{v} = (10, 12.5)\).

WebThe direction vector of the incident ray (= incoming ray) is i, and we assume this vector is normalized. The direction vec-tors of the reflected and transmitted rays are r and t and will be calculated. These vectors are (or will be) normalized as well.
