Product Importance Sampling for Light Transport Path Guiding
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
The efficiency of Monte Carlo algorithms for light transport simulation is directly related to their ability to importance-sample the product of the illumination and reflectance in the rendering equation. Since the optimal ...
Towards a Principled Kernel Prediction for Spatially Varying BSSRDFs
(The Eurographics Association, 2018)
While the modeling of sub-surface translucency using homogeneous BSSRDFs is an established industry standard, applying the same approach to heterogeneous materials is predominantly heuristical. We propose a more principled ...
