Bi-Directional Polarised Light Transport
(The Eurographics Association, 2016)
While there has been considerable applied research in computer graphics on polarisation rendering, no principled investigation of how the inclusion of polarisation information affects the mathematical formalisms that are ...
A Unified Manifold Framework for Efficient BRDF Sampling based on Parametric Mixture Models
(The Eurographics Association, 2018)
Virtually all existing analytic BRDF models are built from multiple functional components (e.g., Fresnel term, normal distribution function, etc.). This makes accurate importance sampling of the full model challenging, and ...
Extended Path Integral Formulation for Volumetric Transport
(The Eurographics Association, 2017)
We propose an extension of the path integral formulation amenable to the expression of volumetric light transport with photon beam estimates. Our main contribution is a generalization of Hachisuka et al.'s extended path ...
