Rendering algorithm; the light is divided in single rays, each with a different behaviour depending on the surface it will hurt. It takes care of many physical laws such as refraction, reflection, etc. It is very realistic but it requires much power in processing.
A procedure used in the graphical determination of the path followed by a ray of radiated energy as it travels through the atmosphere. Ray tracing is used to determine the extent to which a radar's radiation pattern may vary from its standard pattern, based upon the atmospheric model used for the radar. Ray tracings are commonly graphed to illustrate radiation paths.
A rendering technique, based on complex mathematical algorithms, to accurately represent any conceivable representation of light, including reflections and refractions as well as any conceivable surface forms and materials.
A way of rendering a 3D image that follows a path of every ray of light. The light beam may be absorbed or reflected.
This is one way of rendering a picture. The computer computes the path of a light ray from the light source to the objects (from which the ray reflects), and further to the observer. It does the for every pixel on the monitor. This is a very intensive calculation, and the results are incredibly good.
Method of simulating light rays passing through a scene. Ray tracing results from a series of complex calculations, and can be very slow.
(n) A rendering technique that calculates the path of all rays of (a) theoretical light source(s) within a model scene. The technique includes tracing the path from the light source, between all objects which may reflect and pass the light, to the viewer's eye.
A relatively simple algorythm with renders a scene by tracing a ray of light pixel by pixel. Lighting values are calculated as rays travel around the three-dimensional scene affecting the surfaces of objects.
An enhancement technique for computer graphics that simulates the effect of reflected light rays in a three-dimensional scene on a two-dimensional computer screen.
A technique for adding realism to computer models by including variations in shade, colour intensity, and shadows that would be produced by having one or more light sources. Ray tracing software simulates the path of light rays as they would be absorbed or reflected by objects.
A graphical or mathematical approximation scheme for determining the propagation of electromagnetic or sound waves by following the path of rays obeying the laws of reflection and refraction. Applications of ray tracing to atmospheric problems include estimating rainbow angles, determining the characteristics of mirages, and mapping the propagation of sound in the atmosphere and oceans.
a complex technical process whereby a graphical image is enhanced and made to appear more realistic by incorporating shading, shadow, and color. This is accomplished by simulating the way light plays on individual components of the image. Ray tracing software requires a great deal of memory and processing resources and often takes several hours to produce the end effect.
A computer simulation of light used to design optics and to enhance vector data.
Ray tracing is a general technique from geometrical optics of modeling the path taken by light by following rays of light as they interact with optical surfaces. It is used in the design of optical systems, such as camera lenses, microscopes, telescopes and binoculars. The term is also applied to mean a specific rendering algorithmic approach in 3 D computer graphics, where mathematically-modelled visualisations of programmed scenes are produced using a technique which follows rays from the eyepoint outward, rather than originating at the light sources.
