We compute the product of approximated visibility and environment map lighting in a stochastic Monte Carlo volume renderer to steer a joint importance sampling of the direct lighting. Our proposed two-step approach is well suited for dynamic changes in visibility and lighting functions due to a fast sweeping-plane algorithm to estimate visibility. The insets show how our technique (blue) achieves faster convergence with less samples compared to a uniform sampling (red) and importance sampling of the environment map (yellow). Here, 64 samples per pixel have been used. The Manix data set consists of 512×512×460 voxels.

Different ways to visualize the expansion of “Detective #firstName# #surname# #sipped# the #coffee#. It was #coffeeJudgement#, like life”. Right: visualizing the grammar’s connectivity shows how each symbol (in dark blue) can expand to many different options (pale blue). Left: visualizing five sample expansions demonstrates where each story varies or remains the same. Bottom-left: fully expanded text, as it would be read by the end reader (Color figure online).
