An Improved Multiple Importance Sampling Heuristic for Density Estimates in Light Transport Simulations
(The Eurographics Association, 2018)
Vertex connection and merging (VCM) is one of the most robust light transport simulation algorithms developed so far. It combines bidirectional path tracing with photon mapping using multiple importance sampling (MIS). ...
Stochastic Generation of (t, s) Sample Sequences
(The Eurographics Association, 2021)
We introduce a novel method to generate sample sequences that are progressively stratified both in high dimensions and in lower-dimensional projections. Our method comes from a new observation that Owen-scrambled quasi-Monte ...
Impulse Responses for Precomputing Light from Volumetric Media
(The Eurographics Association, 2019)
Modern interactive rendering can rely heavily on precomputed static lighting on surfaces and in volumes. Scattering from volumetric media can be similarly treated using precomputation, but transport from volumes onto ...
Real-time Monte Carlo Denoising with the Neural Bilateral Grid
(The Eurographics Association, 2020)
Real-time denoising for Monte Carlo rendering remains a critical challenge with regard to the demanding requirements of both high fidelity and low computation time. In this paper, we propose a novel and practical deep ...
NeRF-Tex: Neural Reflectance Field Textures
(The Eurographics Association, 2021)
We investigate the use of neural fields for modeling diverse mesoscale structures, such as fur, fabric, and grass. Instead of using classical graphics primitives to model the structure, we propose to employ a versatile ...
Matrix Bidirectional Path Tracing
(The Eurographics Association, 2018)
Sampled paths in Monte Carlo ray tracing can be arbitrarily close to each other due to its stochastic nature. Such clumped samples in the path space tend to contribute little toward an accurate estimate of each pixel. ...
Material and Lighting Reconstruction for Complex Indoor Scenes with Texture-space Differentiable Rendering
(The Eurographics Association, 2021)
Modern geometric reconstruction techniques achieve impressive levels of accuracy in indoor environments. However, such captured data typically keeps lighting and materials entangled. It is then impossible to manipulate the ...
Temporal Coherence for Metropolis Light Transport
(The Eurographics Association, 2017)
Metropolis Light Transport is a powerful global illumination algorithm, yet it has some issues that make it less suitable for animation rendering. Due to the algorithm's local exploration of path space, difficult light ...
Primary Sample Space Path Guiding
(The Eurographics Association, 2018)
Guiding path tracing in light transport simulation has been one of the practical choices for variance reduction in production rendering. For this purpose, typically structures in the spatial-directional domain are built. ...
Fast Analytic Soft Shadows from Area Lights
(The Eurographics Association, 2021)
In this paper, we present the first method to analytically compute shading and soft shadows for physically based BRDFs from arbitrary area lights.We observe that for a given shading point, shadowed radiance can be computed ...
