Vertex Connection and Merging

Computer Graphics · Light Transport · 2012 · also: VCM, UPS · vertex-connection-and-merging.yaml

Treats photon merging as just another sampling technique alongside bidirectional connection, and MIS-weights the two together, so one integrator handles both diffuse interreflection and caustics.

Colour is the family; a dashed line is the second member of it.
