Robust and efficient light-transport simulation based on statistical methods is the subject of renewed research interest, propelled by the desire to accurately render general environments with complex materials and light sources, which is often difficult with current solutions. In addition, it has been recognized that advanced methods, which can render many effects in one pass without excessive tweaking, increase artists' productivity and allow them to focus on their creative work. For this reason, the movie industry is shifting away from approximate rendering solutions toward physically based rendering methods, which poses new challenges in terms of strict requirements on high image quality and algorithm robustness.
