Nonlinearly Weighted First-order Regression for Denoising Monte Carlo Renderings
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We address the problem of denoising Monte Carlo renderings by studying existing approaches and proposing a new algorithm that yields state-of-the-art performance on a wide range of scenes. We analyze existing approaches ...
Path-space Motion Estimation and Decomposition for Robust Animation Filtering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence ...
Portal-Masked Environment Map Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a technique to e ciently importance sample distant, all-frequency illumination in indoor scenes. Standard environment sampling is ine cient in such cases since the distant lighting is typically only visible ...
Progressive Virtual Beam Lights
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
A recent technique that forms virtual ray lights (VRLs) from path segments in media, reduces the artifacts common to VPL approaches in participating media, however, distracting singularities still remain. We present Virtual ...
Photon Beam Diffusion: A Hybrid Monte Carlo Method for Subsurface Scattering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present photon beam diffusion, an efficient numerical method for accurately rendering translucent materials. Our approach interprets incident light as a continuous beam of photons inside the material. Numerically ...
