Color Restoration of Scanned Archaeological Artifacts with Repetitive Patterns
(The Eurographics Association, 2016)
Our work addresses the problem of virtually restoring archaeological artifacts. Virtual restoration is the process of creating a noise-free model of a degraded object, to visualize its original appearance. Our work focuses ...
Pre-convolved Radiance Caching
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both ...
Visualization of Particle-based Data with Transparency and Ambient Occlusion
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Particle-based simulation techniques, like the discrete element method or molecular dynamics, are widely used in many research fields. In real-time explorative visualization it is common to render the resulting data using ...
An Area-Preserving Parametrization for Spherical Rectangles
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present an area-preserving parametrization for spherical rectangles which is an analytical function with domain in the unit rectangle [0;1]2 and range in a region included in the unit-radius sphere. The parametrization ...
Accurate Fitting of Measured Reflectances Using a Shifted Gamma Micro-facet Distribution
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Material models are essential to the production of photo-realistic images. Measured BRDFs provide accurate representation with complex visual appearance, but have larger storage cost. Analytical BRDFs such as Cook- Torrance ...
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 ...
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 ...
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 ...
