One can think of this "ray" as a stream of photons traveling along the same path. In a perfect vacuum this ray will be a straight line (ignoring relativistic effects). Any combination of four things might happen with this light ray: absorption, reflection, refraction and fluorescence. A surface may absorb part of the light ray, resulting in a loss of intensity of the reflected and/or ref…

WebJun 24, 2015 · Ray marching (a.k.a. sphere tracing) Ray marching is a variant of ray casting that permits the use of objects for which there is no analytic formula so that the intersection with the ray cannot be simply computed by solving an algebraic equation.
