Six-rays model. Geometry of the six-ray model with location of antennas of equal heights at any point of the street in top view. The six-rays model is applied in an urban or indoor environment where a radio signal transmitted will encounter some objects that produce reflected, refracted or scattered copies of the transmitted signal.
Sommer Ray. Sommer Ray (born September 15, 1996) is an American social media personality, fitness model, [2] and former competitive bodybuilder.
Streaming algorithm. In computer science, streaming algorithms are algorithms for processing data streams in which the input is presented as a sequence of items and can be examined in only a few passes, typically just one. These algorithms are designed to operate with limited memory, generally logarithmic in the size of the stream and/or in the ...
List of ray tracing software. Ray tracing is a technique that can generate near photo-realistic computer images. A wide range of free software and commercial software is available for producing these images. This article lists notable ray-tracing software. Software.
Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays: propagate in straight ...
In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow. [1] [2] Rays are used to model the propagation of light through an optical system, by dividing the real light ...
Ray casting is a natural modeling tool for making shaded pictures. The grayscale ray-casting system developed by Scott Roth and Daniel Bass at GM Research Labs produced pictures on a Ramtek color raster display around 1979. To compose pictures, the system provided the user with the following controls: View.
