  2. Von Kries coefficient law - Wikipedia

    en.wikipedia.org/wiki/Von_Kries_coefficient_law

    , where ,, and are the cone responses of the same observer, and ,, and are all cone responses of the same observer; the only difference is that ,, and are viewed under a reference illuminant while the other set of values is experimental. α, β, and γ are the von Kries coefficients corresponding to the reduction in sensitivity of the three ...

  3. T5 retrofit conversion - Wikipedia

    en.wikipedia.org/wiki/T5_retrofit_conversion

    T5 retrofit conversion is a means of converting light fittings designed to use T8 format lamps, so that they can use more energy-efficient T5 lamps. [1] This is done by electronically converting the luminaires to high frequency operation.

  4. Stiles–Crawford effect - Wikipedia

    en.wikipedia.org/wiki/Stiles–Crawford_effect

    Stiles, along with his fellow National Physical Laboratory researcher Brian Hewson Crawford, set out to measure the effect of light intensity on pupil size. They constructed an apparatus where two independently controlled beams, both emitted by the same light source, entered the eye: a narrow beam through the center of the pupil, and a wider ...

  5. LMS color space - Wikipedia

    en.wikipedia.org/wiki/LMS_color_space

    LMS (long, medium, short), is a color space which represents the response of the three types of cones of the human eye, named for their responsivity (sensitivity) peaks at long, medium, and short wavelengths. The numerical range is generally not specified, except that the lower end is generally bounded by zero.

    Valorant is a 2020 first-person tactical hero shooter video game developed and published by Riot Games. [3] A free-to-play game, Valorant takes inspiration from the Counter-Strike series, borrowing several mechanics such as the buy menu, spray patterns, and inaccuracy while moving.

  7. Lightmap - Wikipedia

    They are usually flat, without information about the light's direction, whilst some game engines use multiple lightmaps to provide approximate directional information to combine with normal-maps. Lightmaps may also store separate precalculated components of lighting information for semi-dynamic lighting with shaders, such as ambient-occlusion ...

    Counter-Strike 2 is a 2023 free-to-play tactical first-person shooter game developed and published by Valve.It is the fifth entry in the Counter-Strike series, developed as an updated version of the previous entry, Counter-Strike: Global Offensive (2012).

  9. Photon upconversion - Wikipedia

    en.wikipedia.org/wiki/Photon_upconversion

    Optical fiber that contains infrared light shines with a blue color in the dark. Photon upconversion (UC) is a process in which the sequential absorption of two or more photons leads to the emission of light at shorter wavelength than the excitation wavelength. It is an anti-Stokes type emission. An example is the conversion of infrared light ...
