Wineglass with dispersive dielectric materials with 32 samples per pixel. As can be seen, our reweighted schemes improve upon uniform and stratified samples and produces much smoother result in terms of color noise. Significant improvements can be observed in low discrepency sequences. All results are plotted in log-log scale.
