Visualizing Summary Statistics and Uncertainty
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
The graphical depiction of uncertainty information is emerging as a problem of great importance. Scientific data sets are not considered complete without indications of error, accuracy, or levels of confidence. The visual ...
Supporting Exploratory Analysis with the Select and Slice Table
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
In interactive visualization, selection techniques such as dynamic queries and brushing are used to specify and extract items of interest. In other words, users define areas of interest in data space that often have a clear ...
Topology-based Smoothing of 2D Scalar Fields with C1-Continuity
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Data sets coming from simulations or sampling of real-world phenomena often contain noise that hinders their processing and analysis. Automatic filtering and denoising can be challenging: when the nature of the noise is ...
Multi-layer Depth Peeling by Single-Pass Hardware Rasterisation for Faster Isosurface Raytracing on a GPU
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Empty-space skipping is an essential acceleration technique for volume rendering. Image-order empty-space skipping is not well suited to GPU implementation, since it must perform checks on, essentially, a per-sample basis, ...
Non-iterative Second-order Approximation of Signed Distance Functions for Any Isosurface Representation
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Signed distance functions (SDF) to explicit or implicit surface representations are intensively used in various computer graphics and visualization algorithms. Among others, they are applied to optimize collision detection, ...
Visualization and Analysis-Oriented Reconstruction of Material Interfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Reconstructing boundaries along material interfaces from volume fractions is a difficult problem, especially because the under-resolved nature of the input data allows for many correct interpretations. Worse, algorithms ...
Brushing Moments in Interactive Visual Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
We present a systematic study of opportunities for the interactive visual analysis of multi-dimensional scientific data that is based on the integration of statistical aggregations along selected independent data dimensions ...
Hardware-Assisted Projected Tetrahedra
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
We present a flexible and highly efficient hardware-assisted volume renderer grounded on the original Projected Tetrahedra (PT) algorithm. Unlike recent similar approaches, our method is exclusively based on the rasterization ...
SmallWorlds: Visualizing Social Recommendations
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
We present SmallWorlds, a visual interactive graph-based interface that allows users to specify, refine and build item-preference profiles in a variety of domains. The interface facilitates expressions of taste through ...
GraphDice: A System for Exploring Multivariate Social Networks
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Social networks collected by historians or sociologists typically have a large number of actors and edge attributes. Applying social network analysis (SNA) algorithms to these networks produces additional attributes such ...
