Eye-Centered Color Adaptation in Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Color adaptation is a well known ability of the human visual system (HVS). Colors are perceived as constant even though the illuminant color changes. Indeed, the perceived color of a diffuse white sheet of paper is still ...
Boundary-Aware Extinction Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We introduce Boundary-Aware Extinction Maps for interactive rendering of massive heterogeneous volumetric datasets. Our approach is based on the projection of the extinction along light rays into a boundary-aware function ...
Practical Capture and Reproduction of Phosphorescent Appearance
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
This paper proposes a pipeline to accurately acquire, efficiently reproduce and intuitively manipulate phosphorescent appearance. In contrast to common appearance models, a model of phosphorescence needs to account for ...
General Point Sampling with Adaptive Density and Correlations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ...
Analysis and Controlled Synthesis of Inhomogeneous Textures
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Many interesting real-world textures are inhomogeneous and/or anisotropic. An inhomogeneous texture is one where various visual properties exhibit significant changes across the texture's spatial domain. Examples include ...
Spatial Adjacency Maps for Translucency Simulation under General Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Rendering translucent materials in real time is usually done by using surface diffusion and/or (translucent) shadow maps. The downsides of these approaches are, that surface diffusion cannot handle translucency effects ...
Real-Time Linear BRDF MIP-Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a new technique to jointly MIP-map BRDF and normal maps. Starting with generating an instant BRDF map, our technique builds its MIP-mapped versions based on a highly efficient algorithm that interpolates von ...
Multiple Axis-Aligned Filters for Rendering of Combined Distribution Effects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Distribution effects such as diffuse global illumination, soft shadows and depth of field, are most accurately rendered using Monte Carlo ray or path tracing. However, physically accurate algorithms can take hours to ...
From Faces to Outdoor Light Probes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Image-based lighting has allowed the creation of photo-realistic computer-generated content. However, it requires the accurate capture of the illumination conditions, a task neither easy nor intuitive, especially to the ...
Explorative Blood Flow Visualization using Dynamic Line Filtering based on Surface Features
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Rupture risk assessment is a key to devise patient-specific treatment plans of cerebral aneurysms. To understand and predict the development of aneurysms and other vascular diseases over time, both hemodynamic flow patterns ...
