Ray traced global illumination can be partitioned into direct contributions of the light sources that reflect to the camera after one bounce and indirect contributions that scatter for multiple bounces. We propose a new real-time solution called dynamic diffuse global illumination resampling that computes direct and indirect illumination accurately and with low noise. The key idea is to derive a new, unified algorithm from the principles of the state of the art ReSTIR many-lights direct… Expand

Dynamic Diffuse Global Illumination with Ray-Traced Irradiance Fields
We show how to compute global illumination efficiently in scenes with dynamic objects and lighting. We extend classic irradiance probes to a compact encoding of the full irradiance field in a scene.Expand

Spatiotemporal reservoir resampling for real-time ray tracing with dynamic direct lighting
TLDR
This work introduces a new algorithm---ReSTIR--- that renders such lighting interactively, at high quality, and without needing to maintain complex data structures, and derives an unbiased Monte Carlo estimator for this approach, and shows that it achieves equal-error 6×-60× faster than state-of-the-art methods.

An efficient denoising algorithm for global illumination
TLDR
A hybrid ray-tracing/rasterization strategy for realtime rendering enabled by a fast new denoising method that enables efficient (biased) reconstruction by denoised light without blurring materials is proposed. Expand
Spatiotemporal variance-guided filtering: real-time reconstruction for path-traced global illumination
TLDR
A reconstruction algorithm is introduced that generates a temporally stable sequence of images from one path-per-pixel global illumination, using temporal accumulation to increase the effective sample count and spatiotemporal luminance variance estimates to drive a hierarchical, image-space wavelet filter.

Light transport simulation with vertex connection and merging
TLDR
This work presents a reformulation of photon mapping as a bidirectional path sampling technique for Monte Carlo light transport simulation, which allows for a seamless integration of the two methods into a more robust combined rendering algorithm via multiple importance sampling. Expand
Adaptive radiosity textures for bidirectional ray tracing
TLDR
A rendering method designed to provide accurate, general simulation of global illumination for realistic image synthesis, using a three-pass, bidirectional ray tracing algorithm that traces rays from both the lights and the eye. Expand
