Precursors to ray tracing Local illumination Cast one eye ray, then shade according to light Appel (1968) Cast one eye ray + one ray to light 6 Whitted ray-tracing algorithm In 1980, Turner Whitted introduced ray tracing to the graphics community.

Large Ray Packets for Real-time Whitted Ray Tracing
https://cseweb.ucsd.edu/~ravir/whitted.pdf
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- ondary effects, and we expect a corresponding drop in performance for large ray packet algorithms.

Packet-based Whitted and Distribution Ray Tracing
https://www.cs.utah.edu/docs/techreports/2006/pdf/UUCS-06-013.pdf
In this paper, we use the term ray cast- ing to refer to the use of ray tracing for visibility computations only (RCS, Figure 1, left). By adding direct lighting, reflection, and refraction to ray casting, we can implement Whitted’s [1980] well-known algorithm; hence we refer to such a method asWhitted- style ray tracing (WRT, Figure 1, middle).

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 ...

Turner Whitted – ACM SIGGRAPH HISTORY ARCHIVES
https://history.siggraph.org/person/turner-whitted/
John Turner Whitted is an electrical engineer and computer scientist who introduced recursive ray tracingto the computer graphics community with his 1979 paper “An improved illumination model for shaded display”. His algorithm proved to be a practical method of simulating global illumination, inspired many variations, and is in wide use today.
