Arnold of Soissons

Arnold (Arnoul) of Soissons or Arnold or Arnulf of Oudenburg (ca 1040–1087) is a saint of the Roman Catholic Church, the patron saint of hop-pickers and Belgian brewers.

Arnold, born in Brabant, the son of a certain Fulbertus was first a career soldier before settling at the Benedictine St. Medard's Abbey, Soissons, France. He spent his first three years as a hermit, but later rose to be abbot of the monastery. His hagiography states that he tried to refuse this honor and flee—a standard literary trope (compare Jiménez de Cisneros)— but was forced by a wolf to return. He then became a priest and in 1080, bishop of Soissons, another honor that he sought to avoid. When his see was occupied by another bishop, rather than fighting, he took the opportunity to retire from public life, founding the Abbey of St. Peter in Oudenburg.

At the abbey, he began to brew beer, as essential in medieval life as water. He encouraged local peasants to drink beer, instead of water, due to its "gift of health." At the time of the Black Death epidemic, Arnold was an abbot in Oudenburg, Belgium. Rather than stand by while the local Christians drank water, he had them consume his alcoholic brews. Because of this, many people in his church survived the plague. During the process of brewing, the water was boiled and thus, unknown to all, freed of pathogens. This same story is also told of Arnulf or Arnold of Metz, another patron of brewers. There are many depictions of St. Arnold with a mashing rake in his hand, to identify him. He is honored in July with a parade in Brussels on the "Day of Beer."

Arnold (software)

Arnold is an unbiased, physically based, ray tracing 3D rendering application created by the company Solid Angle. Notable films that have used Arnold include Monster House, Cloudy with a Chance of Meatballs, Alice in Wonderland, Thor, Captain America, X-Men: First Class, The Avengers, Red Tails, Underworld: Awakening, Space Pirate Captain Harlock, Elysium, Pacific Rim and Gravity.

Technology

Arnold is based on Monte Carlo Ray Tracing. Thus its engine is optimized to send billions of spatially incoherent rays throughout a scene. It often uses one level of diffuse inter-reflection so that light can bounce off of a wall or other object and indirectly illuminate a subject. For complex scenes such as the space station in Elysium, it makes heavy use of instancing. It uses the Open Shading Language to define the materials and textures.

History

Marcos Fajardo is the chief architect of Arnold. The beginnings of what is now Arnold emerged in 1997 when Fajardo decided to write his own renderer. That year, he attended Siggraph, where his interest in stochastic ray tracing (a foundational part of Arnold's rendering technology) was piqued in discussions with friends attending the conference.
