Bidirectional Rendering of Vector Light Transport
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
On the foundations of many rendering algorithms it is the symmetry between the path traversed by light and its adjoint path starting from the camera. However, several effects, including polarization or fluorescence, break ...
Re‐Weighting Firefly Samples for Improved Finite‐Sample Monte Carlo Estimates
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
Samples with high contribution but low probability density, often called fireflies, occur in all practical Monte Carlo estimators and are part of computing unbiased estimates. For finite‐sample estimates, however, they can ...
