Simultaneous Classification of Time-Varying Volume Data Based on the Time Histogram
(The Eurographics Association, 2006)An important challenge in the application of direct volume rendering to time-varying data is the specification of transfer functions for all time steps. Very little research has been devoted to this problem, however. To ... -
A Spectral Visualization System for Analyzing Financial Time Series Data
(The Eurographics Association, 2006)Visual data analysis of time related data sets has attracted much research interest recently, and a number of sophisticated visualization methods have been proposed in the past. In financial analysis, however, the most ... -
CVSgrab: Mining the History of Large Software Projects
(The Eurographics Association, 2006)Many software projects use Software Configuration Management systems to support their development process. Such systems accumulate in time large amounts of information useful for process accounting and auditing. We study ... -
Structure-accentuating Dense Flow Visualization
(The Eurographics Association, 2006)Vector field visualization approaches can broadly be categorized into approaches that directly visualize local or integrated flow and approaches that analyze the topological structure and visualize extracted features. Our ... -
Enhancing Slice-based Visualizations of Medical Volume Data
(The Eurographics Association, 2006)Slice-based visualizations of CT and MRI data are frequently used for diagnosis, intervention planning and intraoperative navigation since they allow a precise analysis and localization. We present new techniques to enhance ... -
Segmentation of Flow Fields using Pattern Matching
(The Eurographics Association, 2006)Due to the amount of data nowadays, automatic detection, classification and visualization of features is necessary for a thorough inspection of flow data sets. Pattern matching using vector valued templates has already ... -
Integrated Visualization of Morphologic and Perfusion Data for the Analysis of Coronary Artery Disease
(The Eurographics Association, 2006)We present static and dynamic techniques to visualize perfusion data and to relate perfusion data to morphologic image data. In particular, we describe the integrated analysis of MRI myocardial perfusion data with CT ... -
Path Line Oriented Topology for Periodic 2D Time-Dependent Vector Fields
(The Eurographics Association, 2006)This paper presents an approach to extracting a path line oriented topological segmentation for periodic 2D timedependent vector fields. Topological methods aiming in capturing the asymptotic behavior of path lines rarely ... -
Texture Advection on Stream Surfaces: A Novel Hybrid Visualization Applied to CFD Simulation Results
(The Eurographics Association, 2006)Stream surfaces are a classic flow visualization technique used to portray the characteristics of vector fields, and texture advection research has made rapid advances in recent years. We present a novel hybrid visualization ... -
Volume Composition Using Eye Tracking Data
(The Eurographics Association, 2006)This paper presents a method to automate rendering parameter selection, simplifying tedious user interaction and improving the usability of visualization systems. Our approach acquires regions-of-interest for a dataset ... -
Direct Isosurface Extraction from Scattered Volume Data
(The Eurographics Association, 2006)Isosurface extraction is a standard visualization method for scalar volume data and has been subject to research for decades. Nevertheless, to our knowledge, no isosurface extraction method exists that directly extracts ... -
Knowledge-Based Out-of-Core Algorithms for Data Management in Visualization
(The Eurographics Association, 2006)Data management is the very first issue in handling very large datasets. Many existing out-of-core algorithms used in visualization are closely coupled with application-specific logic. This paper presents two knowledgebased ... -
Terrain Rendering using Spherical Clipmaps
(The Eurographics Association, 2006)We describe a terrain rendering algorithm for spherical terrains based on clipmaps. It leverages the high geometry throughput of current GPU to render large static triangle sets. The vertices are displaced by a height map ... -
Efficient Surface Reconstruction from Noisy Data using Regularized Membrane Potentials
(The Eurographics Association, 2006)We present a novel, physically-motivated method for surface reconstruction that can recover smooth surfaces from noisy and sparse data sets, without using orientation information. A new volumetric technique based on ... -
Robust Surface Detection for Variance Comparison and Dimensional Measurement
(The Eurographics Association, 2006)This paper describes a robust method for creating surface models from volume datasets with distorted density values due to artefacts and noise. Application scenario for the presented work is variance comparison and dimensional ... -
Evaluating the Effectiveness of Tree Visualization Systems for Knowledge Discovery
(The Eurographics Association, 2006)User studies, evaluations, and comparisons of tree visualization systems have so far focused on questions that can readily be answered by simple, automated queries without needing visualization. Studies are lacking on the ... -
PhylloTrees: Phyllotactic Patterns for Tree Layout
(The Eurographics Association, 2006)Motivations for drawing hierarchical structures are probably as diverse as datasets to visualize. This ubiquity of tree structures has lead to a manifold of tree layout algorithms and tree visualization systems. While many ... -
Combining Extended Table Lens and Treemap Techniques for Visualizing Tabular Data
(The Eurographics Association, 2006)We present a framework for visualizing large tabular data that combines two views: the table view and the treemap view. The table view extends the known table lens as follows: We cluster related elements to reduce subsampling ... -
