    • Ray tracing is a method to produce realistic images; it determines visible surfaces in an image at the pixel level (Appel, 1968; Kay & Greenberg, 1979; Whitted, 1980). Unlike the z-buffer and BSP tree, ray tracing operates pixel-by-pixel rather than primitive-by-primitive. This tends to make ray tracing relatively slow for scenes with large objects in screen space. However, it has a variety of nice features which often make it the right choice for batch rendering and even for some interactive applications...

    Peter Shirley. Ray tracing

    • Ray tracing is a well known method for photorealistic image synthesis, volume visualization and rendering. Over the last decade the method is being adopted throughout the research community around the world. With the advent of the high speed processing units, the method has been emerging from offline rendering towards real time rendering. The success behind ray tracing algorithms lies in the use of acceleration data structures and modern processing power of CPUs and GPUs...

    • Ray tracing is a rendering technique for producing realistic 3D computer graphics. Compared to traditional scan-line rendering which is generally adopted by graphics pipeline, ray tracing can simulate more realistic global illumination, however, with the cost of expensive computation...

    Chih-chang Chenet al. Use of hardware Z-buffered rasterization to accelerate ray tracing

    • Ray tracing is a computer graphics technique for generating photo-realistic images. To determine the color at each pixel of the image, one traces the path traversed by each ray of light arriving at the pixel back through several reflections and/or refractions. The most time-consuming phase of a ray tracer is ray traversal, which determines for each of a large number of rays, the first object met by that ray. Many data structures have been proposed to accelerate this process...

    • | Ray tracing is a powerful method to determinethe radio channel characteristics. Especially,for broadband transmission and to determine the angleof incidence, which is becoming more important with theintroduction of directional antennas, ray tracing providesuseful and realistic results. Two basic methodsof ray tracing can be distinguished, the imaging methodand the ray launching method...
