Ray Tracing (graphics)
In computer graphics, ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane and simulating the effects of its encounters with virtual objects. The technique is capable of producing a very high degree of visual realism, usually higher than that of typical scanline rendering methods, but at a greater computational cost. This makes ray tracing best suited for applications where the image can be rendered slowly ahead of time, such as in still images and film and television visual effects, and more poorly suited for real-time applications like video games where speed is critical. Ray tracing is capable of simulating a wide variety of optical effects, such as reflection and refraction, scattering, and dispersion phenomena (such as chromatic aberration).

Famous quotes containing the words ray and/or tracing:
“Colleges, in like manner, have their indispensable office,—to teach elements. But they can only highly serve us, when they aim not to drill, but to create; when they gather from far every ray of various genius to their hospitable halls, and, by the concentrated fires, set the hearts of their youth on flame.”
—Ralph Waldo Emerson (1803–1882)
“In mind, she was of a strong and vigorous turn, having from her earliest youth devoted herself with uncommon ardour to the study of the law; not wasting her speculations upon its eagle flights, which are rare, but tracing it attentively through all the slippery and eel-like crawlings in which it commonly pursues its way.”
—Charles Dickens (1812–1870)
