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). ...
MatMorpher: A Morphing Operator for SVBRDFs
(The Eurographics Association, 2021)
We present a novel morphing operator for spatially-varying bidirectional reflectance distribution functions. Our operator takes as input digital materials modeled using a set of 2D texture maps which control the typical ...
Single-image Full-body Human Relighting
(The Eurographics Association, 2021)
We present a single-image data-driven method to automatically relight images with full-body humans in them. Our framework is based on a realistic scene decomposition leveraging precomputed radiance transfer (PRT) and ...
Moment-based Constrained Spectral Uplifting
(The Eurographics Association, 2021)
Spectral rendering is increasingly used in appearance-critical rendering workflows due to its ability to predict colour values under varying illuminants. However, directly modelling assets via input of spectral data is a ...
Diffuse-Specular Separation using Binary Spherical Gradient Illumination
(The Eurographics Association, 2018)
We introduce a novel method for view-independent diffuse-specular separation of albedo and photometric normals without requiring polarization using binary spherical gradient illumination. The key idea is that with binary ...
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 ...
Scalable Real-Time Shadows using Clustering and Metric Trees
(The Eurographics Association, 2018)
Real-time shadow algorithms based on geometry generally produce high quality shadows. Recent works have considerably improved their efficiency. However, scalability remains an issue because these methods strongly depend ...
Modeling Surround-aware Contrast Sensitivity
(The Eurographics Association, 2021)
Despite advances in display technology, many existing applications rely on psychophysical datasets of human perception gathered using older, sometimes outdated displays. As a result, there exists the underlying assumption ...
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 ...
NeLF: Neural Light-transport Field for Portrait View Synthesis and Relighting
(The Eurographics Association, 2021)
Human portraits exhibit various appearances when observed from different views under different lighting conditions. We can easily imagine how the face will look like in another setup, but computer algorithms still fail on ...
