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 ...
Rendering 2021 DL Track: Frontmatter
(The Eurographics Association, 2021)
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
