In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images . On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping ...
Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces." [1] Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games.
The position and color ( hue, saturation, brightness, and contrast) of all pixels, vertices, and/or textures used to construct a final rendered image can be altered using algorithms defined in a shader, and can be modified by external variables or textures introduced by the computer program calling the shader. [citation needed] Shaders are used ...
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.
In optics, a caustic or caustic network [1] is the envelope of light rays which have been reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. [2] The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of ...
AGPL-3.0-or-later [5] Website. www.povray.org. The Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers.
English: A 3D rendered image using ray tracing, rendered by the POV-Ray program. The scene uses very simple lighting, and uniform background colors, to make it easier to interpret differences in global illumination. A relatively low resolution mesh was used (some quality issues could be fixed by using a more detailed mesh).
Look up ray tracing in Wiktionary, the free dictionary. Ray tracing is a method for calculating the path of waves or particles through a system. The method is practiced in two distinct forms: Ray tracing (physics), which is used for analyzing optical and other systems. Ray tracing (graphics), which is used for 3D image generation.
