Photon soup

From Wikipedia, the free encyclopedia

Photon soup is a project that aims to render an image by simulating the motion of all photons in a room. The original simulation in 1991, programmed in C by Richard Keene, took 100 Sun 1 computers operating at 1 MHz a month to render a single image. A recent revision using a smaller number of today's faster computers, with the programs written in the Java programming language, can simulate 10 times as many photons in the same amount of time.
