Metropolis Light Transport | Two Minute Papers #16

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.
