An unbiased ray-marching transmittance estimator
Markus Kettunen, Eugene d'Eon, Jacopo Pantaleoni +1
We present an in-depth analysis of the sources of variance in state-of-the-art unbiased volumetric transmittance estimators, and propose several new methods for improving their eff…
Online path sampling control with progressive spatio-temporal filtering
Jacopo Pantaleoni
This work introduces progressive spatio-temporal filtering, an efficient method to build all-frequency approximations to the light transport distribution into a scene by filtering…
Importance Sampling of Many Lights with Reinforcement Lightcuts Learning
Jacopo Pantaleoni
In this manuscript, we introduce a novel technique for sampling and integrating direct illumination in the presence of many lights. Unlike previous work, the presented technique im…
Blue-Noise Dithered QMC Hierarchical Russian Roulette
Jacopo Pantaleoni
In order to efficiently sample specular-diffuse-glossy and glossy-diffuse-glossy transport phenomena, Tokuyoshi and Harada introduced hierarchical Russian roulette, a smart algorit…
Notes on optimal approximations for importance sampling
Jacopo Pantaleoni, Eric Heitz
In this manuscript, we derive optimal conditions for building function approximations that minimize variance when used as importance sampling estimators for Monte Carlo integration…
Charted Metropolis Light Transport
Jacopo Pantaleoni
In this manuscript, inspired by a simpler reformulation of primary sample space Metropolis light transport, we derive a novel family of general Markov chain Monte Carlo algorithms…
