  2. 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:

  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 size of ...

  4. Ray tracing (graphics) - Wikipedia

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

    Image showing recursively generated rays from the "eye" (and through an image plane) to a light source after encountering two diffuse surfaces. To the right is an image showing a simple example of a path of rays recursively generated from the camera (or eye) to the light source using the above algorithm.

  5. Ray casting - Wikipedia

    en.wikipedia.org/wiki/Ray_casting

    Ray-cast image of idealized universal joint with shadow. Ray casting is the methodological basis for 3D CAD/CAM solid modeling and image rendering. It is essentially the same as ray tracing for computer graphics where virtual light rays are "cast" or "traced" on their path from the focal point of a camera through each pixel in the camera sensor to determine what is visible along the ray in the ...

  6. Pencil (optics) - Wikipedia

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

    In 1675, a pencil was interpreted as a double cone of rays, as from an object point, through a lens, to an image point. Definitions of ray, pencil, and beam in Henry Coddington's 1829 A System of Optics, Part 1. A 1675 work describes a pencil as "a double cone of rays, joined together at the base."

  7. 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.

  9. Specular reflection - Wikipedia

    en.wikipedia.org/wiki/Specular_reflection

    A ray of light is characterized by the direction normal to the wave front (wave normal). When a ray encounters a surface, the angle that the wave normal makes with respect to the surface normal is called the angle of incidence and the plane defined by both directions is the plane of incidence. Reflection of the incident ray also occurs in the ...
