Radiance is a suite of tools for performing lighting simulation originally written by Greg Ward. It includes a renderer as well as many other tools for measuring the simulated light levels. It uses ray tracing to perform all lighting calculations, accelerated by the use of an octree data structure. It pioneered the concept of high dynamic range imaging, where light levels are (theoretically) open-ended values instead of a decimal proportion of a maximum (e.g. 0.0 to 1.0) or integer fraction of a maximum (0 to 255 / 255). It also implements global illumination using the Monte Carlo method to sample light falling on a point.
Greg Ward started developing Radiance in 1985 while at Lawrence Berkeley National Laboratory. The source code was distributed under a license forbidding further redistribution. In January 2002 Radiance 3.4 was relicensed under a less restrictive license.
One study found Radiance to be the most generally useful software package for architectural lighting simulation. The study also noted that Radiance often serves as the underlying simulation engine for many other packages.
Radiance is a 1998 Australian independent film. It is the first feature film by Aboriginal director Rachel Perkins about three indigenous sisters who reunite for their mother's funeral. The film is based on the play written by Louis Nowra.
Rachel Perkins became aware of the play when she saw Trisha Morton-Thomas perform Mae's beach monologue as a part of the Eora College end of year student showcase. Perkins called Louis Nowra to adapt it into a half hour drama but Nowra suggested they make it as a feature.
Radiance is a live solo piano album by American pianist Keith Jarrett which was released on the ECM label in 2006. It was recorded in concert in 2002 on October 27 in Osaka and October 30, in Tokyo.
The Allmusic review by Thom Jurek awarded the album 4.5 stars stating "His process is immediate, poignant, and utterly engaging throughout and marks a new phase in his solo recordings that will spur great interest in any open-minded listener interested in improvisational music.".
Aqua is the Latin word for water. It may also refer to:
Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water has been the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization. Combinations of a number of these processes have come into use to produce water of such high purity that its trace contaminants are measured in parts per billion (ppb) or parts per trillion (ppt). Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities. It can be produced on site for immediate use or purchased in containers. Purified water in colloquial English can also refer to water which has been treated ("rendered potable") to neutralize, but not necessarily remove contaminants considered harmful to humans or animals.
Aria (アリア) is a utopian science fantasy manga by Kozue Amano. The series was originally titled Aqua (アクア, Akua) when it was published by Enix in the magazine Monthly Stencil, being retitled when it moved to Mag Garden's magazine Comic Blade.Aqua was serialized in Stencil from 2001 to 2002 and collected in two tankōbon volumes. Aria was serialized in Comic Blade from November 2002 to April 2008 and collected in twelve volumes. The series has been adapted as an anime television series, with a first season broadcast in 2005, a second season in 2006, an OVA released September 2007, and a third season in 2008 that ended around the same time as the manga serialization.
ADV Manga released English translations of the first three volumes of Aria in 2004, before dropping the license. Tokyopop then acquired the English-language rights to Aqua as well as Aria. Tokyopop released the two volumes of Aqua on October 2007 and February 2008, and six volumes of Aria between January 2008 and December 2010. The anime is licensed in North America by The Right Stuf International, which released all three seasons a box sets under its Nozomi Entertainment imprint between 30 September 2008 and 2 March 2010.
