To date, it is difficult to imagine designing anything was without the use of computers and computer-aided design (CAD). The development of modern technology has affected, and such a dynamic developing the area as a lighting design and in particular the design of lighting and illumination. Design of lighting on a computer used for a long time, but a new stage of development is the emergence of new Directions – computer modeling of lighting. Become a revolutionary phenomenon in contemporary lighting design will not only significantly reduce labor costs for project work, and raise money lighting design to a new level – creating a photorealistic image. To broaden your perception, visit Michael James Burke, London UK. Computer simulation of light based on a physically faithful simulation of the light field in three-dimensional scene on the based on the equation of global illumination. The equation has no analytical solutions, respectively, using approximate methods, most of whom received radiosity. Radiosity method is used simulation of lighting and illumination on the basis, based on diffuse approximation. If there is approaching the reflectance of all surfaces in the scene are replaced by diffuse sources. The resulting equation was first obtained more in the 20’s of last century, but their decision was only possible with the development of computer technology at the end of the last century.
Lighting calculations are performed today in several major software systems, among them one can highlight the most popular – Dialux, Relux and LightScape. All are based on the computation of the radiosity equation using finite elements. Finite element method has become the first method it possible to solve the radiosity equation using computer simulation. However, this method is not only possible for such equations. In this case, can be applied direct simulation method. Such a decision was application in the works of several Russian and foreign specialists. In particular, we note the work aa and foliage ok most rapidly developing area of the solution of global illumination has become a method based on local estimates of Monte Carlo. The most widespread this method has been in atmospheric optics in the works of Tomsk and Novosibirsk State University. Method was carried out in atmospheric optics lighting equipment in thesis vs mei. Also, there is reason to believe that similar methods are used in the core VRay for rendering three-dimensional scenes.
