What is cornellbox?
Cornell Box refers to a kind of assemblage construction, often in the form of a shadow box, such as "Toward the Blue Peninsula" (above). Likewise, this is a site that is composed of many disparate and seemingly unrelated elements.
In computer rendering, a Cornell box (named after Cornell University rather than the artist) is a room with specified figures and lighting to test a number of conditions to see how well they are rendered. If you are looking for that kind of information, perhaps instead you want to go here.
