Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, textures, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene. The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output.
Catharism was a Christian quasi-dualist or pseudo-Gnostic movement which thrived in Southern Europe, particularly in northern Italy and southern France, between the 12th and 14th centuries. Denounced as a heretical sect by the Catholic Church, its followers were attacked first by the Albigensian Crusade and later by the Medieval Inquisition, which eradicated the sect by 1350. Many thousands were slaughtered, hanged, or burnt at the stake, sometimes without regard for "age or sex."
François-Marie Arouet, known by his nom de plumeM. de Voltaire, was a French Enlightenment writer, philosopher (philosophe), satirist, and historian. Famous for his wit and his criticism of Christianity and of slavery, Voltaire was an advocate of freedom of speech, freedom of religion, and separation of church and state.
Crowd simulation is the process of simulating the movement of a large number of entities or characters. It is commonly used to create virtual scenes for visual media like films and video games, and is also used in crisis training, architecture and urban planning, and evacuation simulation.
Non-photorealistic rendering (NPR) is an area of computer graphics that focuses on enabling a wide variety of expressive styles for digital art, in contrast to traditional computer graphics, which focuses on photorealism. NPR is inspired by other artistic modes such as painting, drawing, technical illustration, and animated cartoons. NPR has appeared in movies and video games in the form of cel-shaded animation as well as in scientific visualization, architectural illustration and experimental animation.
A discrete-event simulation (DES) models the operation of a system as a (discrete) sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. Between consecutive events, no change in the system is assumed to occur; thus the simulation time can directly jump to the occurrence time of the next event, which is called next-event time progression.
Arnaud Amalric was a Cistercian abbot who played a prominent role in the Albigensian Crusade. It is reported that prior to the massacre of Béziers, Amalric, when asked how to distinguish Cathars from Catholics, responded, "Kill them [all], for God knows which are His own."
The Intel Personal SuperComputer was a product line of parallel computers in the 1980s and 1990s. The iPSC/1 was superseded by the Intel iPSC/2, and then the Intel iPSC/860.
Cathar castles are a group of medieval castles located in the Languedoc region. Some had a Cathar connection in that they offered refuge to dispossessed Cathars in the thirteenth century. Many of these sites were replaced by new castles built by the victorious French Crusaders and the term Cathar castle is also applied to these fortifications despite their having no connection with Cathars. The fate of many Cathar castles, at least for the early part of the Crusade, is outlined in the contemporary Occitan "Chanson de la Croisade", translated into English as the "Song of the Cathar Wars ".
The Aggregate Level Simulation Protocol (ALSP) is a protocol and supporting software that enables simulations to interoperate with one another. Replaced by the High Level Architecture (simulation) (HLA), it was used by the US military to link analytic and training simulations.
Dualism in cosmology or dualistic cosmology is the moral or spiritual belief that two fundamental concepts exist, which often oppose each other. It is an umbrella term that covers a diversity of views from various religions, including both traditional religions and scriptural religions.
The Architecture Design and Assessment System (ADAS) was a set of software programs offered by the Research Triangle Institute from the mid-1980s until the early 1990s.
Heresy is any belief or theory that is strongly at variance with established beliefs or customs, particularly the accepted beliefs or religious law of a religious organization. A heretic is a proponent of heresy.
Reverse computation is a software application of the concept of reversible computing.
Extended static checking (ESC) is a collective name in computer science for a range of techniques for statically checking the correctness of various program constraints. ESC can be thought of as an extended form of type checking. As with type checking, ESC is performed automatically at compile time. This distinguishes it from more general approaches to the formal verification of software, which typically rely on human-generated proofs. Furthermore, it promotes practicality over soundness, in that it aims to dramatically reduce the number of false positives at the cost of introducing some false negatives. ESC can identify a range of errors that are currently outside the scope of a type checker, including division by zero, array out of bounds, integer overflow and null dereferences.
SpiNNaker is a massively parallel, manycore supercomputer architecture designed by the Advanced Processor Technologies Research Group (APT) at the Department of Computer Science, University of Manchester. It is composed of 57,600 processing nodes, each with 18 ARM9 processors and 128 MB of mobile DDR SDRAM, totalling 1,036,800 cores and over 7 TB of RAM. The computing platform is based on spiking neural networks, useful in simulating the human brain.
Toby L. J. Howard is an Honorary Reader in the Department of Computer Science at the University of Manchester in the UK. He was appointed Lecturer in 1985, and was Director of Undergraduate Studies in the Department 2011–2019. He retired from the University in 2020 and was appointed to an Honorary position.
"Caedite eos. Novit enim Dominus qui sunt eius." is a phrase reportedly spoken by the commander of the Albigensian Crusade, prior to the massacre at Béziers on 22 July 1209. A direct translation of the Medieval Latin phrase is "Kill them. The Lord knows those that are his own". Papal legate and Cistercian abbot Arnaud Amalric was the military commander of the Crusade in its initial phase and leader of this first major military action of the Crusade, the assault on Béziers, and was reported by Caesarius of Heisterbach to have uttered the order.
Joseph de La Porte, was an 18th-century French priest, literary critic, poet and playwright.
Gabriel A. Wainer is a Canadian/Argentinian computer scientist known for his work in modeling and simulation. He is a Professor in the Department of Systems and Computer Engineering at Carleton University in Ottawa, Canada.
