Ray tracing of a beam of light passing through a medium with changing refractive index.The ray is advanced by a small amount, and then the direction is re-calculated. Ray tracing works by assuming that the particle or wave can be modeled as a large number of very narrow beams (), and that there exists some distance, possibly very small, over which such a ray is locally straight.
A meridional ray is a ray that passes through the axis of an optical fiber. A skew ray is a ray that travels in a non-planar zig-zag path and never crosses the axis of an optical fiber. A guided ray, bound ray, or trapped ray is a ray in a multi-mode optical fiber, which is confined by the core.
Ray tracing is a method for calculating the path of waves or particles through a system. The method is practiced in two distinct forms: The method is practiced in two distinct forms: Ray tracing (physics) , which is used for analyzing optical and other systems

Ray tracing has long been gaming's holy grail. A method of creating hyper-realistic lighting and graphics, for years ray tracing has been promised as the technology that will take games the next ...
A ray trace through a prism with apex angle α. Regions 0, 1, and 2 have indices of refraction, , and , and primed angles ′ indicate the ray's angle after refraction.. Ray angle deviation and dispersion through a prism can be determined by tracing a sample ray through the element and using Snell's law at each interface.
While wave-based models rely on the principles of Maxwell's equations, particle models use ray optics and Monte Carlo methods to simulate light paths. Monte Carlo Ray Tracing: A stochastic method used in light transport simulations to compute global illumination. This method leverages randomness to estimate solutions to the rendering equation ...
