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. Simple recursive implementations of ray tracing are still occasionally referred to as Whitted-style ray tracing.

Early life and education

Whitted was born in Durham, North Carolina and grew up in Winston-Salem. Whitted took his BSE and MS degrees in electrical engineering from Duke University, then received his PhD from North Carolina State University in 1978 and joined
