Joint path sampling: image comparisonBelow we demonstrate the integration of our new path sampling techniques into unidirectional path tracing, bidirectional path tracing, as well as the virtual ray lights method. We compare our results against the traditional (i.e. original) versions of these algorithms. For anisotropic media we use the Henyey-Greenstein phase function with scattering anisotropy g=0.9. In the image labels, "X-conn." refers to "X-random-decision connections", as designated in the paper. Note that each individual comparison (i.e. image pair) has been tone mapped slightly differently.
