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 ...
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 ...
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 ...
A Compact Representation for Fluorescent Spectral Data
(The Eurographics Association, 2021)
We propose a technique to efficiently importance sample and store fluorescent spectral data. Fluorescence behaviour is properly represented as a re-radiation matrix: for a given input wavelength, this matrix indicates how ...
Approximate svBRDF Estimation From Mobile Phone Video
(The Eurographics Association, 2018)
We describe a new technique for obtaining a spatially varying BRDF (svBRDF) of a flat object using printed fiducial markers and a cell phone capable of continuous flash video. Our homography-based video frame alignment ...
Spectral Primary Decomposition for Rendering with sRGB Reflectance
(The Eurographics Association, 2019)
Spectral renderers, as-compared to RGB renderers, are able to simulate light transport that is closer to reality, capturing light behavior that is impossible to simulate with any three-primary decomposition. However, ...
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 ...
Screen Space Approximate Gaussian Hulls
(The Eurographics Association, 2018)
The Screen Space Approximate Gaussian Hull method presented in this paper is based on an output sensitive, adaptive approach, which addresses the challenge of high quality rendering even for high resolution displays and ...
A Microfacet Model for Specular Fluorescent Surfaces and Fluorescent Volume Rendering using Quantum Dots
(The Eurographics Association, 2023)
Fluorescent appearance of materials results from a complex light-material interaction phenomenon. The modeling of fluorescent material for rendering has only been addressed through measurement or for simple diffuse ...
