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 ...
On the Advancement of BTF Measurement on Site
(The Eurographics Association, 2018)
We present our progress to the on-site measurement of the spatially varying surface reflectance represented by bidirectional texture function (BTF). This requires a physical realization of a portable instrument that can ...
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 ...
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 ...
Statistical Characterization of Surface Reflectance
(The Eurographics Association, 2014)
The classification of surface reflectance functions as diffuse, specular, and glossy has been introduced by Heckbert more than two decades ago. Many rendering algorithms are dependent on such a classification, as different ...
Weathering of Urban Scenes: Challenges and Possible Solutions
(The Eurographics Association, 2016)
In this paper, we propose to discuss on one of the main challenges in realistic rendering of urban scenes: changes in appearance over time within a urban context. After studying the previous work on weathering techniques, ...
Practical Experiences with Using Autocollimator for Surface Reflectance Measurement
(The Eurographics Association, 2016)
We present our experiences with using an autocollimator to set up the surface reflectance measurement for both BRDF and BTF. Assuming the measured material appearance is put on a locally flat surface, the autocollimator ...
Towards a Practical Gamut of Appearance Acquisition
(The Eurographics Association, 2013)
We propose discussing the performance of appearance modeling in terms of supported material and illumination gamut. While we have a precise understanding of the cost of any given appearance modeling method, performance is ...
BTF-based Material Representations: Current Challenges
(The Eurographics Association, 2013)
The development of Bidirectional Texture Functions (BTFs) has made it possible for a wide range of different materials to acquire their characteristic appearance from a real-world counterpart and reproduce it faithfully ...
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 ...
