2. Ray tracing (physics) - Wikipedia

   en.wikipedia.org/wiki/Ray_tracing_(physics)

   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.

3. Ray (optics) - Wikipedia

   en.wikipedia.org/wiki/Ray_(optics)

   The principal ray or chief ray (sometimes known as the b ray) in an optical system is the meridional ray that starts at an edge of an object and passes through the center of the aperture stop. [ 5 ] [ 8 ] [ 7 ] The distance between the chief ray (or an extension of it for a virtual image) and the optical axis at an image location defines the ...

4. Caustic (optics) - Wikipedia

   en.wikipedia.org/wiki/Caustic_(optics)

   Caustics are formed in the regions where sufficient photons strike a surface causing it to be brighter than the average area in the scene. “Backward ray tracing” works in the reverse manner beginning at the surface and determining if there is a direct path to the light source. [7] Some examples of 3D ray-traced caustics can be found here.

5. Ray tracing (graphics) - Wikipedia

   en.wikipedia.org/wiki/Ray_tracing_(graphics)

   This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. (c. 2008) 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.

   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 ...

7. Light transport theory - Wikipedia

   en.wikipedia.org/wiki/Light_transport_theory

   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 ...

9. Ray transfer matrix analysis - Wikipedia

   en.wikipedia.org/wiki/Ray_transfer_matrix_analysis

   The ray tracing technique is based on two reference planes, called the input and output planes, each perpendicular to the optical axis of the system. At any point along the optical train an optical axis is defined corresponding to a central ray; that central ray is propagated to define the optical axis further in the optical train which need ...
