Fig. 19From: A linear heuristic for multiple importance samplingComparison of MIS weighting schemes for the direct lighting problem of computer graphics. The left part is the image rendered with 100 rays per pixel, the right part is weight \(\alpha\) of the light source sampling. The RMSE is computed as the average of 10 independent executions. The [0,1] interval of possible \(\alpha\) values is visualized by the color barBack to article page
