Radiosity (computer Graphics)

picture info	Radiosity (computer Graphics) In 3D computer graphics, radiosity is an application of the finite element method to solving the rendering equation for scenes with surfaces that reflect light diffusely. Unlike rendering methods that use Monte Carlo algorithms (such as path tracing), which handle all types of light paths, typical radiosity only account for paths (represented by the code "LDE") which leave a light source and are reflected diffusely some number of times (possibly zero) before hitting the eye. Radiosity is a global illumination algorithm in the sense that the illumination arriving on a surface comes not just directly from the light sources, but also from other surfaces reflecting light. Radiosity is viewpoint independent, which increases the calculations involved, but makes them useful for all viewpoints. Radiosity methods were first developed in about 1950 in the engineering field of heat transfer. They were later refined specifically for the problem of rendering computer graphics in 19 ...

	Gauss–Seidel Method In numerical linear algebra, the Gauss–Seidel method, also known as the Liebmann method or the method of successive displacement, is an iterative method used to solve a system of linear equations. It is named after the German mathematicians Carl Friedrich Gauss and Philipp Ludwig von Seidel. Though it can be applied to any matrix with non-zero elements on the diagonals, convergence is only guaranteed if the matrix is either strictly diagonally dominant, or symmetric and positive definite. It was only mentioned in a private letter from Gauss to his student Gerling in 1823. A publication was not delivered before 1874 by Seidel. Description Let \mathbf A\mathbf x = \mathbf b be a square system of linear equations, where: \mathbf A = \begin a_ & a_ & \cdots & a_ \\ a_ & a_ & \cdots & a_ \\ \vdots & \vdots & \ddots & \vdots \\a_ & a_ & \cdots & a_ \end, \qquad \mathbf = \begin x_ \\ x_2 \\ \vdots \\ x_n \end , \qquad \mathbf = \begin b_ \\ b_2 \\ \vdots \\ b_n \end.

	Nusselt Analog Ernst Kraft Wilhelm Nußelt (Nusselt in English; November 25, 1882, in Nuremberg – September 1, 1957, in Munich) was a German engineer. Nusselt studied mechanical engineering at Technische Universität München, where he got his doctorate in 1907. He taught in Dresden from 1913 to 1917. During this teaching tenure he developed the dimensional analysis of heat transfer, without any knowledge of the Buckingham π theorem or any other developments of Lord Rayleigh. In so doing he opened the door for further heat transfer analysis. After teaching and working in Switzerland and Germany between 1917 and 1925, he was appointed to the chair of theoretical mechanics in Munich. There he made important developments in the field of heat exchangers. He held that position until 1952, being succeeded in the job by another important figure in the field of heat transfer, Ernst Schmidt. The Nusselt number used in Fluid Mechanics and Heat Transfer Heat transfer is a discipline of thermal e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Dimensionless Number Dimensionless quantities, or quantities of dimension one, are quantities implicitly defined in a manner that prevents their aggregation into unit of measurement, units of measurement. ISBN 978-92-822-2272-0. Typically expressed as ratios that align with another system, these quantities do not necessitate explicitly defined Unit of measurement, units. For instance, alcohol by volume (ABV) represents a volumetric ratio; its value remains independent of the specific Unit of volume, units of volume used, such as in milliliters per milliliter (mL/mL). The 1, number one is recognized as a dimensionless Base unit of measurement, base quantity. Radians serve as dimensionless units for Angle, angular measurements, derived from the universal ratio of 2π times the radius of a circle being equal to its circumference. Dimensionless quantities play a crucial role serving as parameters in differential equations in various technical disciplines. In calculus, concepts like the unitless ratios ...

	Lambert's Cosine Law In optics, Lambert's cosine law says that the observed radiant intensity or luminous intensity from an ideal diffusely reflecting surface or ideal diffuse radiator is directly proportional to the cosine of the angle ''θ'' between the observer's line of sight and the surface normal; .RCA Electro-Optics Handbook, p.18 ffModern Optical Engineering, Warren J. Smith, McGraw-Hill, p. 228, 256 The law is also known as the cosine emission law or Lambert's emission law. It is named after Johann Heinrich Lambert, from his '' Photometria'', published in 1760. A surface which obeys Lambert's law is said to be ''Lambertian'', and exhibits Lambertian reflectance. Such a surface has a constant radiance/luminance, regardless of the angle from which it is observed; a single human eye perceives such a surface as having a constant brightness, regardless of the angle from which the eye observes the surface. It has the same radiance because, although the emitted power from a given area ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Heat In thermodynamics, heat is energy in transfer between a thermodynamic system and its surroundings by such mechanisms as thermal conduction, electromagnetic radiation, and friction, which are microscopic in nature, involving sub-atomic, atomic, or molecular particles, or small surface irregularities, as distinct from the macroscopic modes of energy transfer, which are thermodynamic work and transfer of matter. For a closed system (transfer of matter excluded), the heat involved in a process is the difference in internal energy between the final and initial states of a system, after subtracting the work done in the process. For a closed system, this is the formulation of the first law of thermodynamics. Calorimetry is measurement of quantity of energy transferred as heat by its effect on the states of interacting bodies, for example, by the amount of ice melted or by change in temperature of a body. In the International System of Units (SI), the unit of measurement for he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	View Factor Acornsoft was the software arm of Acorn Computers, and a major publisher of software for the BBC Micro and Acorn Electron. As well as games, it also produced a large number of educational titles, extra computer languages and business and utility packages – these included word processor ''VIEW'' and the spreadsheet '' ViewSheet'' supplied on ROM and cartridge for the BBC Micro/ Acorn Electron and included as standard in the BBC Master and Acorn Business Computer. History Acornsoft was formed in late 1980 by Acorn Computers directors Hermann Hauser and Chris Curry, and David Johnson-Davies, author of the first game for a UK personal computer and of the official Acorn Atom manual "Atomic Theory and Practice". David Johnson-Davies was managing director and in early 1981 was joined by Tim Dobson, Programmer and Chris Jordan, Publications Editor. While some of their games were clones or remakes of popular arcade games (e.g. ''Hopper'' is a clone of Sega's '' Frogger'', '' S ...

	Electric Image Animation System The Electric Image Animation System (EIAS) is a 3D computer graphics package published by EIAS3D. It currently runs on the macOS and Windows platforms. History Electric Image, Inc. was initially a visual effects production company. They developed their own in-house 3D animation and rendering package for the Macintosh beginning in the late 1980s, calling it ElectricImage Animation System. (To avoid confusion with the current product with its similar name, we will refer to this initial incarnation of the product simply as ''ElectricImage''.) When the company later decided to offer their software for sale externally, it quickly gained a customer base that lauded the developers for the software's exceptionally fast rendering engine and high image quality. Because it was capable of film-quality output on commodity hardware, ElectricImage was popular in the movie and television industries throughout the decade. It was used by the "Rebel Unit" at Industrial Light and Magic quite extensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
