Whitted Ray-Tracing. Figure 2: image produced by Turner Whitted with the algorithm he developed in 1980. Now that the distinction between ray-tracing and light transport algorithm was established, we can finally introduce one of the most classical examples of light transport algorithm based on ray-tracing. The technique was first detailed in ...

In Whitted Ray Tracingwe computed lighting very crudely Phong + specular global lighting In Distributed Ray Tracingwe want to compute the lighting as accurately as possiblelighting as accurately as possible Use the formalism of Radiometry Compute irradiance at each pixel(by integrating all the iiliht)incoming light)
Large Ray Packets for Real-time Whitted Ray Tracing
https://cseweb.ucsd.edu/~ravir/whitted.pdf
We aim to employ large ray packet algorithms to achieve real-time Whitted ray tracing, but ray coherence is much less reliable in this domain. Beyond primary visibility, Whitted ray tracing re-quires secondary rays for point-light shadows, reflections, and re-fractions. According to [6], ray coherence degrades for these sec-

Whitted ray-tracing algorithm ! In 1980, Turner Whitted introduced ray tracing to the graphics community. ! Combines eye ray tracing + rays to light ! Recursively traces rays ! Algorithm: 1. For each pixel, trace a primary ray in direction V to the first visible surface. 2. For each intersection, trace secondary rays: ! Shadow rays in ...
Photorealistic Rendering and the Ray-Tracing Algorithm
https://www.pbr-book.org/3ed-2018/Introduction/Photorealistic_Rendering_and_the_Ray-Tracing_Algorithm
Turner Whitted’s original paper on ray tracing emphasized its recursive nature, which was the key that made it possible to include indirect specular reflection and transmission in rendered images. For example, if a ray from the camera hits a shiny object like a mirror, we can reflect the ray about the surface normal at the intersection point ...

We'll call these flows “light rays.” wLight rays travel in straight lines in free space. wLight rays do not interfere with each other as they cross. wLight rays obey the laws of reflection and refraction. wLight rays travel from the light sources to the eye, but the physics is invariant under path reversal (reciprocity). 4 Eye vs. light ray tracing
