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 ... -
Appearance-Driven Automatic 3D Model Simplification
(The Eurographics Association, 2021)We present a suite of techniques for jointly optimizing triangle meshes and shading models to match the appearance of reference scenes. This capability has a number of uses, including appearance-preserving simplification ... -
Fast Polygonal Splatting using Directional Kernel Difference
(The Eurographics Association, 2021)Depth-of-field (DoF) filtering is an important image-processing task for producing blurred images similar to those obtained with a large aperture camera lens. DoF filtering applies an image convolution with a spatially ... -
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 ... -
Semantic-Aware Generative Approach for Image Inpainting
(The Eurographics Association, 2021)We propose a semantic-aware generative method for image inpainting. Specifically, we divide the inpainting process into two tasks; estimating the semantic information inside the masked areas and inpainting these regions ... -
Practical Product Sampling for Single Scattering in Media
(The Eurographics Association, 2021)Efficient Monte-Carlo estimation of volumetric single scattering remains challenging due to various sources of variance, including transmittance, phase-function anisotropy, geometric cosine foreshortening, and squared-distance ... -
Importance Sampling of Glittering BSDFs based on Finite Mixture Distributions
(The Eurographics Association, 2021)We propose an importance sampling scheme for the procedural glittering BSDF of Chermain et al. [CSDD20]. Glittering BSDFs have multi-lobe visible normal distribution functions (VNDFs) which are difficult to sample. They ... -
Sampling Clear Sky Models using Truncated Gaussian Mixtures
(The Eurographics Association, 2021)Parametric clear sky models are often represented by simple analytic expressions that can efficiently generate plausible, natural radiance maps of the sky, taking into account expensive and hard to simulate atmospheric ... -
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 ... -
Zero-variance Transmittance Estimation
(The Eurographics Association, 2021)We apply zero-variance theory to the Volterra integral formulation of volumetric transmittance.We solve for the guided sampling decisions in this framework that produce zero-variance ratio tracking and next-flight ratio ... -
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 ... -

Joint SVBRDF Recovery and Synthesis From a Single Image using an Unsupervised Generative Adversarial Network
(The Eurographics Association, 2020)We want to recreate spatially-varying bi-directional reflectance distribution functions (SVBRDFs) from a single image. Pro- ducing these SVBRDFs from single images will allow designers to incorporate many new materials in ... -
Temporal Sample Reuse for Next Event Estimation and Path Guiding for Real-Time Path Tracing
(The Eurographics Association, 2020)Good importance sampling is crucial for real-time path tracing where only low sample budgets are possible. We present two efficient sampling techniques tailored for massively-parallel GPU path tracing which improve next ... -
Multi-Scale Appearance Modeling of Granular Materials with Continuously Varying Grain Properties
(The Eurographics Association, 2020)Many real-world materials such as sand, snow, salt, and rice are comprised of large collections of grains. Previously, multiscale rendering of granular materials requires precomputing light transport per grain and has ... -
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 ... -
Temporal Normal Distribution Functions
(The Eurographics Association, 2020)Specular aliasing can make seemingly simple scenes notoriously hard to render efficiently: small geometric features with high curvature and near specular reflectance result in tiny lighting features which are difficult to ... -

The Challenges of Releasing the Moana Island Scene
(The Eurographics Association, 2019)A tremendous amount of research has been done over the years using the Stanford bunny, the Cornell box and recently somewhat more complicated data sets. Yet, none of these data sets come close to representing the complexity ... -
De-lighting a High-resolution Picture for Material Acquisition
(The Eurographics Association, 2019)We propose a deep-learning based method for the removal of shades, projected shadows and highlights from a single picture of a quasi-planar surface captured in natural lighting conditions with any kind of camera device. ...
