Example of our stylized scattering. Left: physically correct single scattering using the original occluders. The leaves of the tree block most of the light, causing a rather subtle effect. Right: stylized scattering with occluder manipulation. Using our system, an artist can easily add holes into the shadow map of the tree, producing more pronounced scattering effects. While physically incorrect, it is not obvious for the viewer that the right image uses fake occlusion information. Surface shadows are created from the original shadow map.

The 95% confidence interval highlighted in green for the t-distribution with 4 degrees of freedom (N = 5, N = 3 and α = 0.05). The left most image shows the two-sided confidence interval, while the middle and right image show the one-sided confidence intervals. The areas highlighted in red fall outside the interval.

We compare our method to conventional and gradient-domain path tracing in an equal-time comparison. Gradient-domain path reusing produces visually pleasant images with much less noise than path tracing and significantly lower artifacts than gradient-domain path tracing given the same time.

The variation threshold is set to 60% of the maximum variation. The ensembles are illustrated by the small black icons on top.

Gene t-SNE maps are robust and reproducible across donors. (A) The combined gene t-SNE map, showing previously reported stable gene modules (23). The map separates the 32 modules and shows their relationships. (B) The gene maps for each of the six donor brains. The maps are made using independent data sets, so they reflect the robustness of spatial gene expression patterns in the human brain. Data was pre-processed as in the original publication (23) to enable direct comparison of the WGCNA modules to the gene t-SNE maps.
