Original sentence: (This confusion frequently shows up in marketing jargon for commercial software packages - for instance, LightWave has a "radiosity" option for global illumination that is actually more akin to irradiance caching
Edited sentence: Likewise, Radiosity, by Hugo Elias describes a deterministic.Povray, for example, implements a global illumination method known as final gathering, but mistakenly refers to it as radiosity.Radiosity refers specifically to solving the rendering equation after linearizing it via discrete patches.There are many global illumination algorithms, and sometimes, they are all mistakenly referred.a system of equations, thus it should not be confused with the classic radiosity method.path tracing algorithm that takes advantage of graphics hardware to accelerate irradiance gathering, by using hemicubes.this method does indeed compute the radiosity of patches, it does not compute form factors or explicitly construct.to as radiosity methods
