Tessellation-Independent Smooth Shadow Boundaries
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We propose an efficient and light-weight solution for rendering smooth shadow boundaries that do not reveal the tessellation of the shadow-casting geometry. Our algorithm reconstructs the smooth contours of the underlying ...
Critical Points of Gaussian-Distributed Scalar Fields on Simplicial Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Simulations and measurements often result in scalar fields with uncertainty due to errors or output sensitivity estimates. Methods for analyzing topological features of such fields usually are not capable of handling all ...
Using Visualization to Explore Original and Anonymized LBSN Data
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present GSUVis, a visualization tool designed to provide better understanding of location-based social network (LBSN) data. LBSN data is one of the most important sources of information for transportation, marketing, ...
VIMTEX: A Visualization Interface for Multivariate, Time-Varying, Geological Data Exploration
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Observing interactions among chemical species and microorganisms in the earth's sub-surface is a common task in the field of geology. Bioremediation experiments constitute one such class of interactions which focus on ...
Visual Analysis of Spatio-Temporal Data: Applications in Weather Forecasting
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Weather conditions affect multiple aspects of human life such as economy, safety, security, and social activities. For this reason, weather forecast plays a major role in society. Currently weather forecasts are based on ...
Visual Analytics for Correlation-Based Comparison of Time Series Ensembles
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
An established approach to studying interrelations between two non-stationary time series is to compute the 'windowed' cross-correlation (WCC). The time series are divided into intervals and the cross-correlation between ...
A Shot at Visual Vulnerability Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Increasing the safety of vehicles is an important goal for vehicle manufacturers. These manufacturers often turn to simulations to understand how to improve a vehicle's design as real-world safety tests are expensive and ...
Detangler: Visual Analytics for Multiplex Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
A multiplex network has links of different types, allowing it to express many overlapping types of relationships. A core task in network analysis is to evaluate and understand group cohesion; that is, to explain why groups ...
Quantitative Measures for Cartogram Generation Techniques
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Cartograms are used to visualize geographically distributed data by scaling the regions of a map (e.g., US states) such that their areas are proportional to some data associated with them (e.g., population). Thus the ...
Visualization of Object-Centered Vulnerability to Possible Flood Hazards
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
As flood events tend to happen more frequently, there is a growing demand for understanding the vulnerability of infrastructure to flood-related hazards. Such demand exists both for flood management personnel and the general ...
