Illustrative Rendering of Vortex Cores
(The Eurographics Association, 2013)
Vortices are features crucial for understanding transitional and turbulent flow fields, and have often been visualized using isosurfaces, hulls, and line-like structures. However, they have not been represented in a ...
Parallelized Global Brain Tractography
(The Eurographics Association, 2013)
Most brain tractography algorithms suffer from lower accuracy, because they use only information in a certain neighborhood and reconstruct the tracts independently. Global brain tractography algorithms compensate the lack ...
Hierarchical Poisson-Disk Sampling for Fiber Stipples
(The Eurographics Association, 2013)
To understand neural tracts of the brain, neuroscientists use visualizations of diffusion data. Fiber stippling - a technique inspired by illustrations - accommodates probabilistic tracts, main diffusion direction, and ...
PointAO - Improved Ambient Occlusion for Point-based Visualization
(The Eurographics Association, 2013)
The visualization of large amounts of particles, glyphs, and other point-based data plays an important role in many fields of science, among them flow mechanics, molecular dynamics, and medical imaging. The proper perception ...
