1991 K. Hafner & J. Markoff Cyberpunk iii. 289 Robert Morris was writing a program called a ray tracer for a graduate-level computer graphics course. A ray tracer produces images of three-dimensional scenes.

1994 Personal Computer World Nov. 430/3 The ray-tracer can generate a substantial amount of information during and after the render.

2006 Sci. Amer. (U.K. ed.) Aug. 63/1 When I turn on these effects in a ray tracer..I can get a reflection of a shadow of a puff of smoke.
