Practical Product Sampling for Single Scattering in Media
(The Eurographics Association, 2021)
Efficient Monte-Carlo estimation of volumetric single scattering remains challenging due to various sources of variance, including transmittance, phase-function anisotropy, geometric cosine foreshortening, and squared-distance ...
Stochastic Generation of (t, s) Sample Sequences
(The Eurographics Association, 2021)
We introduce a novel method to generate sample sequences that are progressively stratified both in high dimensions and in lower-dimensional projections. Our method comes from a new observation that Owen-scrambled quasi-Monte ...
