Areograph is the commercial name of a photographic technology that assembles photographic components into 3-dimensional environments. Anywhere from 100,000 to several million photographs are stitched by software into a navigable scene, akin to those in a first person shooter. The production of such environments is both faster and cheaper than creating a rendered environment of similar size, as well as being more detailed, given that the source of an Areograph environment is a real-world location. The technology is currently used in the Casebook series of games.
