Radiosity (computer graphics) Scene rendered with RRV [1] (simple implementation of radiosity renderer based on OpenGL) 79th iteration. 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 ...
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 ...
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.
Radiant exitance. In radiometry, radiant exitance or radiant emittance is the radiant flux emitted by a surface per unit area, whereas spectral exitance or spectral emittance is the radiant exitance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
Radiant intensity, denoted Ie,Ω ("e" for "energetic", to avoid confusion with photometric quantities, and "Ω" to indicate this is a directional quantity), is defined as [1] where. Ω is the solid angle. In general, Ie,Ω is a function of viewing angle θ and potentially azimuth angle. For the special case of a Lambertian surface, Ie,Ω ...
Irradiance. In radiometry, irradiance is the radiant flux received by a surface per unit area. The SI unit of irradiance is the watt per square metre (W⋅m −2 ). The CGS unit erg per square centimetre per second (erg⋅cm −2 ⋅s −1) is often used in astronomy. Irradiance is often called intensity, but this term is avoided in radiometry ...
Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality. Fundamentally, the algorithm is integrating over all the illuminance arriving to a single point on the surface of an object. This illuminance is then reduced by a surface reflectance ...
Radiosity is a method which attempts to simulate the way in which directly illuminated surfaces act as indirect light sources that illuminate other surfaces. This produces more realistic shading and seems to better capture the ' ambience ' of an indoor scene.
