Geometric Accuracy Analysis of Stationary BTF Gonioreflectometers
(The Eurographics Association, 2015)The accurate BTF data representation requires specialized measurement gantries, some of them designed as gonireflectometers. These consist of an illumination source and a camera mounted on two robotic arms, one degree of ... -
Grand Challenges: Material Models in the Automotive Industry
(The Eurographics Association, 2013)Material reflectance definitions are core to high fidelity visual simulation of objects within a compelling 3D scene. In the automotive industry these are used across the entire business process: from conceptualisation of ... -
High-Quality Multi-Spectral Reflectance Acquisition with X-Rite TAC7
(The Eurographics Association, 2017)When relighting digitized objects, strong color deviations can arise depending on the illumination conditions if the object’s reflectance is only captured in RGB. To guarantee color-correct simulations, it is therefore of ... -
ICL Multispectral Light Stage: Building a Versatile LED Sphere with Off-the-shelf Components
(The Eurographics Association, 2018)We describe the design and implementation of a versatile multispectral light stage (LED sphere) consisting of 168 RGB and color temperature controllable white (W+) lamps, respectively. The light stage is powered with two ... -
Identifying Diffraction Effects in Measured Reflectances
(The Eurographics Association, 2015)There are two different physical models connecting the micro-geometry of a surface and its physical reflectance properties (BRDF). The first, Cook-Torrance, assumes geometrical optics: light is reflected and masked by the ... -
Image-based Fitting of Procedural Yarn Models
(The Eurographics Association, 2018)While common in real life, rendering fiber and cloth accurately is challenging. Recent fiber-based, procedural rendering approaches proved to be able to capture a great amount of details of real yarn. However, the current ... -
Image-based Remapping of Material Appearance
(The Eurographics Association, 2017)Digital 3D content creation requires the ability to exchange assets across multiple software applications. For many 3D asset types, standard formats and interchange conventions are available. For material definitions, ... -
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 ... -
In Praise of an Alternative BRDF Parametrization
(The Eurographics Association, 2015)In this paper, we extend the work of Neumann et al. [NNSK99] and Stark et al. [SAS05] to a pair of 4D BRDF parameterizations with explicit changes of variables. We detail their mathematical properties and relationships to ... -
Interactive Appearance Design in the Presence of Optically Complex
(The Eurographics Association, 2013)In this position paper, we discuss the usability of different material representations for interactive appearance design in the context of visual prototyping. We emphasize the importance of methods explicitly considering ... -
Interactive Appearance Prediction for Cloudy Beverages
(The Eurographics Association, 2016)Juice appearance is important to consumers, so digital juice with a slider that varies a production parameter or changes juice content is useful. It is however challenging to render juice with scattering particles quickly ... -
Intuitive Editing of Visual Appearance from Real-World Datasets
(The Eurographics Association, 2017)Computer-generated imagery is ubiquitous, spanning fields such as games and movies, architecture, engineering, or virtual prototyping, while also helping create novel ones such as computational materials. With the increase ... -
Iso Photographic Rendering
(The Eurographics Association, 2018)In the field of computer graphics, the simulation of the visual appearance of materials requires an accurate computation of the light transport equation. Consequently, material models need to take into account various ... -
Isotropic BRDF Measurements with Quantified Uncertainties
(The Eurographics Association, 2016)Image-based BRDF measurements on spherical material samples present a great opportunity to shorten significantly the acquisition time with respect to more traditional, non-multiplexed measurement methods for isotropic ... -
Linear Models for Material BTFs and Possible Applications
(The Eurographics Association, 2015)Due to the richness of real-world materials, arguably one of the biggest challenges in rendering is to come up with models that describe their appearance well. The image-based bidirectional texture function (BTF) is known ... -
Linear Transport Theory and Applications to Rendering
(The Eurographics Association, 2014)In this talk, I will give an overview of one-dimensional Linear Transport Theory, which concerns itself with the study of random scattering and absorption processes and the inference of large-scale behavior from simple ... -
