ReSTIR GI: Path Resampling for Real-Time Path Tracing

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 significant challenge for path tracing, even when augmented with state-of-the …

CloudLight: A System for Amortizing Indirect Lighting in Real-Time Rendering

This paper describes the CloudLight system for computing indirect lighting asynchronously on an abstracted, computational "cloud," in support of real-time rendering for interactive 3D applications on a local client device. We develop and evaluate …

The SGGX microflake distribution

We introduce the Symmetric GGX (SGGX) distribution to represent spatially-varying properties of anisotropic microflake participating media. Our key theoretical insight is to represent a microflake distribution by the projected area of the …

Interactive Indirect Illumination Using Voxel Cone Tracing

Indirect illumination is an important element for realistic image synthesis, but its computation is expensive and highly dependent on the complexity of the scene and of the BRDF of the involved surfaces. While off-line computation and pre-baking can …
