  2. Ray tracing (physics) - Wikipedia

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

    In physics, ray tracing is a method for calculating the path of waves or particles through a system with regions of varying propagation velocity, absorption characteristics, and reflecting surfaces. Under these circumstances, wavefronts may bend, change direction, or reflect off surfaces, complicating analysis.

  3. Ray (optics) - Wikipedia

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

    Historically, ray tracing involved analytic solutions to the ray's trajectories. In modern applied physics and engineering physics, the term also encompasses numerical solutions to the Eikonal equation. For example, ray-marching involves repeatedly advancing idealized narrow beams called rays through the medium by discrete amounts. Simple ...

    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 ...

  6. 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 ...

  7. 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.

  8. Geometrical optics - Wikipedia

    en.wikipedia.org/wiki/Geometrical_optics

    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:
