单词 radiosity
释义
radiosity

Chemical Engineering
  • Used to calculate the thermal radiation heat transfer exchange between surfaces, it is the sum of the emissive power and the portion of the radiation that is reflected by a surface. By conveniently combining the radiation being emitted by and reflected from a surface, it is useful in determining the net thermal energy exchange between multiple surfaces.


Computer
  • A method used in computer graphics for producing photorealistic images but originating from thermal engineers in the 1950s. The scene is divided into many small objects and accurate modelling of diffuse interreflection between objects is calculated (see diffuse reflection). This results in a large number of simultaneous equations to be solved, so the method is not the fastest available. The energy input to the system comes from the light sources. See also clustering.
