  2. Radiosity (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Radiosity_(computer_graphics)

    The Cornell box, rendered with and without radiosity by BMRT. In 3D computer graphics, radiosity is an application of the finite element method to solving the rendering equation for scenes with surfaces that reflect light diffusely. Unlike rendering methods that use Monte Carlo algorithms (such as path tracing), which handle all types of light ...

  3. Radiosity (radiometry) - Wikipedia

    en.wikipedia.org/wiki/Radiosity_(radiometry)

    In radiometry, radiosity is the radiant flux leaving (emitted, reflected and transmitted by) a surface per unit area, and spectral radiosity is the radiosity of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. [1] The SI unit of radiosity is the watt per square ...

  4. Ray tracing (graphics) - Wikipedia

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

    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. On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping ...

  5. Radiosity - Wikipedia

    en.wikipedia.org/wiki/Radiosity

    Radiosity may refer to: Radiosity (radiometry), the total radiation (emitted plus reflected) leaving a surface, certainly including the reflected radiation and the emitted radiation. Radiosity (computer graphics), a rendering algorithm which gives a realistic rendering of shadows and diffuse light. Category: Disambiguation pages.

  6. Radiant exitance - Wikipedia

    en.wikipedia.org/wiki/Radiant_exitance

    Radiant exitance. Radiant exitance of a surface, denoted Me ("e" for "energetic", to avoid confusion with photometric quantities), is defined as [1] where ∂ is the partial derivative symbol, Φe is the radiant flux emitted, and A is the surface area. If we want to talk about the radiant flux received by a surface, we speak of irradiance.

  7. Color bleeding (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Color_bleeding_(computer...

    Color bleeding real time (Lightsprint middle-ware) In computer graphics and 3D rendering, color bleeding is the phenomenon in which objects or surfaces are colored by reflection of colored light from nearby surfaces. This is a visible effect that appears when a scene is rendered with Radiosity or full global illumination, or can otherwise be ...

  8. Radiance - Wikipedia

    en.wikipedia.org/wiki/Radiance

    Radiance is used to characterize diffuse emission and reflection of electromagnetic radiation, and to quantify emission of neutrinos and other particles. The SI unit of radiance is the watt per steradian per square metre (W·sr−1·m−2). It is a directional quantity: the radiance of a surface depends on the direction from which it is being ...

  9. History of television - Wikipedia

    en.wikipedia.org/wiki/History_of_television

    History of television. Family watching TV, 1958. The concept of television is the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a ...
