Staircase1 equal spp comparison
Equal-sample comparison of direct illumination estimated by MC (uniform light and BSDF sampling with the balance heuristics, 40 SPP), Salaün et al. Order 1 polynomial applied to MC, our method applied to MC, and an MIS combination of two light sampling techniques (Trained and Uniform, 20 SPP per technique) with balance heuristic, power heuristic and optimal weights (Kondapaneni et al [2019]).
