On the Nature of Perceptual Translucency
(The Eurographics Association, 2020)Translucency is an appearance attribute used to characterize materials with some degree of subsurface light transport. Although translucency as a radiative transfer inside the medium is relatively well understood, translucency ... -
A Taxonomy of Bidirectional Scattering Distribution Function Lobes for Rendering Engineers
(The Eurographics Association, 2020)We propose a taxonomy and terminology for rendering engineers to use in describing the main categories of mathematical lobes that are combined to implement bidirectional scattering distribution functions (BSDFs). Bringing ... -
Bonn Appearance Benchmark
(The Eurographics Association, 2020)There is a general shortage of standardized comparisons in the field of appearance modeling. We therefore introduce a benchmark for assessing the quality of reflectance models on a dataset of high quality material measurements ... -
A Genetic Algorithm Based Heterogeneous Subsurface Scattering Representation
(The Eurographics Association, 2020)In this paper, we present a novel heterogeneous subsurface scattering (sss) representation, which is based on a combination of Singular Value Decomposition (SVD) and genetic optimization techniques. To find the best ... -
The Problem of Entangled Material Properties in SVBRDF Recovery
(The Eurographics Association, 2020)SVBRDF (spatially varying bidirectional reflectance distribution function) recovery is concerned with deriving the material properties of an object from one or more images. This problem is particularly challenging when the ... -
Improving Spectral Upsampling with Fluorescence
(The Eurographics Association, 2020)Modern photorealistic rendering simulates spectral behaviour of light. Since many assets are still created in different RGB color spaces, spectral upsampling of the RGB colors to a spectral representation is required to ... -
An Adaptive Metric for BRDF Appearance Matching
(The Eurographics Association, 2020)Image-based BRDF matching is a special case of inverse rendering, where the parameters of a BRDF model are optimized based on a photograph of a homogeneous material under natural lighting. Using a perceptual image metric, ... -

Neural Appearance Synthesis and Transfer
(The Eurographics Association, 2019)Appearance acquisition is a challenging problem. Existing approaches require expensive hardware and acquisition times are long. Alternative ''in-the-wild'' few-shot approaches provide a limited reconstruction quality. ... -
Comparative Study of Layered Material Models
(The Eurographics Association, 2019)The accurate reproduction of layered materials is an important part of physically-based rendering applications. Since no exact analytical model exists for any configuration of layer stacks, available models make approximations. ... -
Estimating Homogeneous Data-driven BRDF Parameters from a Reflectance Map under Known Natural Lighting
(The Eurographics Association, 2019)In this paper we demonstrate robust estimation of the model parameters of a fully-linear data-driven BRDF model from a reflectance map under known natural lighting. To regularize the estimation of the model parameters, we ... -
What is the Reddening Effect and does it really exist?
(The Eurographics Association, 2019)The simulation of light-matter interaction is a major challenge in computer graphics. Particularly challenging is the modelling of light-matter interaction of rough surfaces, which contain several different scales of ... -
On Visual Attractiveness of Anisotropic Effect Coatings
(The Eurographics Association, 2019)With the global trend in customer preference towards achromatic car colors, color designers in coating industry strive to create novel design-critical appearances based on novel effect pigments. At microscopic scale, the ... -
Rendering Transparent Materials with a Complex Refractive Index: Semi-conductor and Conductor Thin Layers
(The Eurographics Association, 2019)During physical simulation of light transport, we separate materials between conductors and dielectrics. The former have a complex refractive index and are treated as opaque, the latter a real one and are treated as ... -
Spectral Rendering with the Bounded MESE and sRGB Data
(The Eurographics Association, 2019)In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After ... -
Fresnel Equations Considered Harmful
(The Eurographics Association, 2019)Microfacet shading models in film and game production have long used a simple approximation to the Fresnel equations, published by Schlick in 1994. Recently a growing number of film studios have transitioned to using the ... -

Towards a Principled Kernel Prediction for Spatially Varying BSSRDFs
(The Eurographics Association, 2018)While the modeling of sub-surface translucency using homogeneous BSSRDFs is an established industry standard, applying the same approach to heterogeneous materials is predominantly heuristical. We propose a more principled ... -
Towards Physically Based Material Appearance in the Thermal Infrared Spectrum: A Short Survey
(The Eurographics Association, 2018)In the context of photorealistic rendering, global illumination mainly relies on material models from the visible spectrum, whereas thermal infrared signatures receive only little attention. This paper outlines physical ... -
Deep Dual Loss BRDF Parameter Estimation
(The Eurographics Association, 2018)Surface parameter estimation is an essential field in computer games and movies. An exact representation of a real-world surface allows for a higher degree of realism. Capturing or artistically creating these materials is ...
