Ray tracing is a computer graphics technique that produces realistic images of a three-dimensional scene. In 1987, Paul Heckbert (then at Pixar) announced a contest to produce a ray tracer in the minimum amount of code, as he describes in "A Minimal Ray Tracer." In 2009, Andrew Kensler (then at the University of Utah Scientific Computing and Imaging Institute) created a C++ version that can fit on a business card. Fabien Sanglard explicates this amazing piece of code in "Decyphering the Business Card Raytracer."
