Improved Sparse Seeding for 3D Electrostatic Field Lines
(The Eurographics Association, 2015)
We present an improved seeding strategy for sparse visualization of electrostatic fields. By analyzing the curvature of the field lines, we extract points of extremal field strength between charges of different sign and ...
Interactive Hierarchical Quote Extraction for Content Insights
(The Eurographics Association, 2019)
This work presents a new approach to visually summarize large micro-document collections such as tweets. We extract frequent patterns of phrases as shortened quotes to present analysts an overview of popular snippets and ...
Visual Analysis of Public Transport Vehicle Movement
(The Eurographics Association, 2012)
Public transport vehicles record detailed operational logs. In major networks, this quickly amounts to massive datasets. Traditionally, these are analysed only using statistical tools, yet they show great potential for the ...
Web-based Volume Rendering using Progressive Importance-based Data Transfer
(The Eurographics Association, 2018)
WebGL 2.0 makes it possible to implement efficient volume rendering that runs in browsers using 3D textures and complex fragment shaders. However, a typical bottleneck for web-based volume rendering is the size of the ...
Voronoi-Based Foveated Volume Rendering
(The Eurographics Association, 2019)
Foveal vision is located in the center of the field of view with a rich impression of detail and color, whereas peripheral vision occurs on the side with more fuzzy and colorless perception. This visual acuity fall-off can ...
State-of-the-Art Report in Web-based Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In this report, we review the current state of the art of web-based visualization applications. Recently, an increasing number of web-based visualization applications have emerged. This is due to the fact that new technologies ...
Direct Visualization of Particle-Partition of Unity Data
(The Eurographics Association, 2011)
Direct visualization of higher-order data provides manifold advantages over the traditional approach, which is based on resampling and subsequent visualization by interpolation-based techniques. Most important, it avoids ...
Local Extraction of Bifurcation Lines
(The Eurographics Association, 2013)
We present local extraction of bifurcation lines together with extraction of their manifolds, a topological feature that has not yet been sufficiently recognized in scientific visualization. The bifurcation lines are ...
Power Efficiency of Volume Raycasting on Mobile Devices
(The Eurographics Association, 2017)
Power efficiency is one of the most important factors for the development of compute-intensive applications in the mobile domain. In this work, we evaluate and discuss the power consumption of a direct volume rendering app ...
Inspector Gadget: Integrating Data Preprocessing and Orchestration in the Visual Analysis Loop
(The Eurographics Association, 2015)
Nowadays, tracking devices are small and cheap. For analysis tasks, there is no problem to obtain sufficient amounts of data. The challenge is how to make sense of the data, which often contain complex situations. Multiple ...
