Physics Tutorial: Refraction and the Ray Model of Light

In nature, a light source emits a ray of light which travels, eventually, to a surface that interrupts its progress. 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… Web13. dec 2006 · According to Whitted [4], the Ray Tracing rendering method can simulate shadows, true reflection and refraction. The latter two were also investigated by de Greve [5] while writing a ray tracer ... over maximum flight radiusWeb23. máj 2016 · In a recursive ray tracer, the simple implementation would be to shoot a ray for reflection and a ray for refraction, then do a weighted sum using the Fresnel.
