Evaluation of the Visibility of Vessel Movement Features in Trajectory Visualizations
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
There are many visualizations that show the trajectory of a moving object to obtain insights in its behavior. In this user study, we test the performance of three of these visualizations with respect to three movement ...
A Shader Framework for Rapid Prototyping of GPU-Based Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper, we present a rapid prototyping framework for GPU-based volume rendering. Therefore, we propose a dynamic shader pipeline based on the SuperShader concept and illustrate the design decisions. Also, important ...
Anatomy-Guided Multi-Level Exploration of Blood Flow in Cerebral Aneurysms
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
For cerebral aneurysms, the ostium, the area of inflow, is an important anatomic landmark, since it separates the pathological vessel deformation from the healthy parent vessel. A better understanding of the inflow ...
Depth of Field Effects for Interactive Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper, a method for interactive direct volume rendering is proposed for computing depth of field effects, which previously were shown to aid observers in depth and size perception of synthetically generated images. ...
Exploring Collections of Tagged Text for Literary Scholarship
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Modern literary scholars must combine access to vast collections of text with the traditional close analysis of their field. In this paper, we discuss the design and development of tools to support this work. Based on ...
Complete Tensor Field Topology on 2D Triangulated Manifolds embedded in 3D
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This paper is concerned with the extraction of the surface topology of tensor fields on 2D triangulated manifolds embedded in 3D. In scientific visualization topology is a meaningful instrument to get a hold on the structure ...
Dynamic Insets for Context-Aware Graph Navigation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Maintaining both overview and detail while navigating in graphs, such as road networks, airline route maps, or social networks, is difficult, especially when targets of interest are located far apart. We present a navigation ...
Visual Boosting in Pixel-based Visualizations
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Pixel-based visualizations have become popular, because they are capable of displaying large amounts of data and at the same time provide many details. However, pixel-based visualizations are only effective if the data set ...
Energy-scale Aware Feature Extraction for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In the visualization of flow simulation data, feature detectors often tend to result in overly rich response, making some sort of filtering or simplification necessary to convey meaningful images. In this paper we present ...
Visual Reconstructability as a Quality Metric for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We present a novel approach for the evaluation of 2D flow visualizations based on the visual reconstructability of the input vector fields. According to this metric, a visualization has high quality if the underlying data ...
