Single scattering in heterogenous participating media
Cyril Delalandre, Pascal Gautron, Jean‐Eudes Marvie, Guillaume François · 2010
The interaction between light and light-transmitting objects, known as participating media, involves complex physical phenomena such as light absorption and scattering. Media such as clouds, smoke and translucent materials often feature heterogeneous scattering properties. Hence the radiance transmitted by the medium potentially depends on such varying properties on the entire light paths, yielding soft light shafts and opacity variations (Figure 1).
