Differentiable physically-based rendering has become an indispensable tool for solving
inverse problems involving light. Most applications in this area jointly optimize a large set of …

Differentiable rendering computes derivatives of the light transport equation with respect to
arbitrary 3D scene parameters, and enables various applications in inverse rendering and …

Physically based differentiable rendering algorithms propagate derivatives through realistic
light transport simulations and have applications in diverse areas including inverse …

Image-space auxiliary features such as surface normal have significantly contributed to the
recent success of Monte Carlo (MC) reconstruction networks. However, path-space features …

Rendering radiative transfer through media with a heterogeneous refractive index is
challenging because the continuous refractive index variations result in light traveling along …

We introduce a general framework for transforming biased estimators into unbiased and
consistent estimators for the same quantity. We show how several existing unbiased and …

Complex visual effects such as caustics are often produced by light paths containing
multiple consecutive specular vertices (dubbed specular chains), which pose a challenge to …

Caustics are interesting patterns caused by the light being focused when reflecting off glossy
materials. Rendering them in computer graphics is still challenging: they correspond to high …

Caustics are complex optical effects caused by the light being concentrated in a small area
due to reflection or refraction on surfaces with low roughness, typically under a sharp light …

This document provides additional derivations concerning integration and sampling of GGX
distribution on polygonal domains, building up to C++ fragments. We also include a brief …
