Automatic Parameter Control for Metropolis Light Transport | Two Minute Papers #30
155Photorealistic rendering (also called global illumination) enables us to see how digital objects would look like in real life. It is an amazingly powerful tool in the hands of a professional artist, who can create breathtaking images or animations with. Metropolis light transport is an advanced photorealistic rendering technique that is remarkably effective at finding the brighter regions of a scene and building many light paths that target these regions. The resulting algorithm is more efficient than traditional random path building algorithms, such as path tracing. This algorithm endeavors to choose an optimal mixture between naive random path sampling techniques (such as path tracing and bidirectional path tracing) and Metropolis Light Transport.
