abstract = "This work aims to build a comparison basis for analyzing global
illumination methods. We have compared six state-of-the-art global
illumination methods, ranging from Monte Carlo Path Tracing
techniques to Density Estimation methods such as Progressive
Photon Mapping, and the mixture approach Vertex Connection and
Merging, using nine test scenes with very different
characteristics, including many different light types,
illumination conditions and BRDFs, exploring many different light
scattering events. In order to compare results, the perceptual
quality metrics SSIM and HDR-VDP-2 were used. We provide a
complete set of convergence rate curves and results for all test
scenes and all analyzed methods. We also discuss strategies to
generate reference images for each case. We concluded that in
general cases the overhead introduced by BPT and VCM is well
compensated by the quality of the produced images, however VCM can
handle more interesting effects. We also showed there are usual
cases such as interiors with strong indirect illumination in which
Light Tracing method excels.",
