This paper is focused on the Bidirectional Reflectance Distribution Function (BRDF) in the
context of algorithms for computational production of realistic synthetic images. We provide a …

Efficiently rendering direct lighting from millions of dynamic light sources using Monte Carlo
integration remains a challenging problem, even for off-line rendering systems. We …

We present a method for reducing errors---variance and bias---in physically based
differentiable rendering (PBDR). Typical applications of PBDR repeatedly render a scene as …

This book explores the methods needed for creating and manipulating HDR content. HDR is
a step change from traditional imaging; more closely matching what we see with our eyes. In …

This book provides a fundamental understanding of global illumination algorithms. It
discusses a broad class of algorithms for realistic image synthesis and introduces a …

We present a robust, unbiased technique for intelligent light‐path construction in path‐
tracing algorithms. Inspired by existing path‐guiding algorithms, our method learns an …

Even with the advent of hardware‐accelerated ray tracing in modern GPUs, only a small
number of rays can be traced at each pixel in real‐time applications. This presents a …

As scenes become ever more complex and real-time applications embrace ray tracing, path
sampling algorithms that maximize quality at low sample counts become vital. Recent …

Multidimensional lightcuts is a new scalable method for efficiently rendering rich visual
effects such as motion blur, participating media, depth of field, and spatial anti-aliasing in …

Differentiable rendering is frequently used in gradient descent-based inverse rendering
pipelines to solve for scene parameters–such as reflectance or lighting properties–from …
