  2. Luminous efficiency function - Wikipedia

    en.wikipedia.org/wiki/Luminous_efficiency_function

    Φ v is the luminous flux, in lumens; Φ e,λ is the spectral radiant flux, in watts per nanometre; y (λ), also known as V(λ), is the luminosity function, dimensionless; λ is the wavelength, in nanometres. Formally, the integral is the inner product of the luminosity function with the spectral power distribution. [2]

  3. Illuminance - Wikipedia

    en.wikipedia.org/wiki/Illuminance

    Illuminance diagram with units and terminology. In photometry, illuminance is the total luminous flux incident on a surface, per unit area. [1] It is a measure of how much the incident light illuminates the surface, wavelength-weighted by the luminosity function to correlate with human brightness perception. [2]

  4. Color confinement - Wikipedia

    en.wikipedia.org/wiki/Color_confinement

    In quantum chromodynamics (QCD), color confinement, often simply called confinement, is the phenomenon that color-charged particles (such as quarks and gluons) cannot be isolated, and therefore cannot be directly observed in normal conditions below the Hagedorn temperature of approximately 2 tera kelvin (corresponding to energies of ...

  6. Rendering equation - Wikipedia

    en.wikipedia.org/wiki/Rendering_equation

    The rendering equation describes the total amount of light emitted from a point x along a particular viewing direction, given a function for incoming light and a BRDF.. In computer graphics, the rendering equation is an integral equation in which the equilibrium radiance leaving a point is given as the sum of emitted plus reflected radiance under a geometrical optics approximation.

    en.wikipedia.org/wiki/CIE_1931_color_space

    X 10 Y 10 Z 10 (also written XYZ 10 and analogously for the following) is the XYZ-style color space defined using the CIE 1964 10° observer CMFs. [26] The 3 CMFs are mainly derived from Stiles and Burch's RGB color-matching functions, [ 27 ] which unlike the Wright–Guild functions (and the subsequent Judd–Vos corrections) are "directly ...
