The Bounced Z-buffer for Indirect Visibility
(The Eurographics Association, 2015)
Synthesizing images of animated scenes with indirect illumination and glossy materials at interactive frame rates commonly ignores indirect shadows. In this work we extend a class of indirect lighting algorithms that splat ...
Illumination-Driven Opacity Modulation for Expressive Volume Rendering
(The Eurographics Association, 2012)
Using classical volume visualization, typically a couple of isosurface layers are rendered semi-transparently to show the internal structures contained in the data. However, the opacity transfer function is often difficult ...
The Recognition of Ethnic Groups based on Histological Skin Properties
(The Eurographics Association, 2011)
We present an algorithm to recognize ethnic groups based on biologically justified features, such as melanin or hemoglobin concentrations. These biophysical features are extracted from skin reflectance spectra and allow, ...
Bent Normals and Cones in Screen-space
(The Eurographics Association, 2011)
Ambient occlusion (AO) is a popular technique for real-time as well as offline rendering. One of its benefits is a gain in efficiency due to the fact that occlusion and shading are decoupled which results in an average ...
Screen Space Spherical Harmonic Occlusion
(The Eurographics Association, 2012)
In this paper we present a new algorithm for real-time directional occlusion sampling. We combine the real-time capabilities of Screen Space Ambient Occlusion (SSAO) with the Spherical Harmonics (SH) representation of local ...
Dense and Scalable Reconstruction from Unstructured Videos with Occlusions
(The Eurographics Association, 2017)
Depth-map-based multi-view stereo algorithms typically recover textureless surfaces by assuming smoothness per view, so they require processing different views to solve occlusions. Moreover, the highly redundant viewpoints ...
Illustrative Rendering of Particle Systems
(The Eurographics Association, 2013)
Sets of particles are a frequently used tool for the exploration of time-varying flow fields due to their ease of use and conceptual simplicity. Understanding temporal changes in such particle systems can be difficult with ...
Reflection Separation in Light Fields based on Sparse Coding and Specular Flow
(The Eurographics Association, 2016)
We present a method to separate a dichromatic reflection component from diffuse object colors for the set of rays in a 4D light field such that the separation is consistent across all subaperture views. The separation model ...
Supporting Urban Search & Rescue Mission Planning through Visualization-Based Analysis
(The Eurographics Association, 2014)
We propose a visualization system for incident commanders in urban search & rescue scenarios that supports access path planning for post-disaster structures. Utilizing point cloud data acquired from unmanned robots, ...
Fast Accurate Soft Shadows with Adaptive Light Source Sampling
(The Eurographics Association, 2012)
Physically accurate soft shadows in 3D applications can be simulated by taking multiple samples from all over the area light source and accumulating them. Due to the unpredictability of the size of the penumbra regions, ...
