Evaluation of Illustration-inspired Techniques for Time-varying Data Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Illustration-inspired techniques have provided alternative ways to visualize time-varying data. Techniques such as speedlines, flow ribbons, strobe silhouettes and opacity-based techniques provide temporal context to the ... -
Exploratory Visualization of Animal Kinematics Using Instantaneous Helical Axes
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We present novel visual and interactive techniques for exploratory visualization of animal kinematics using instantaneous helical axes (IHAs). The helical axis has been used in orthopedics, biomechanics, and structural ... -
Extraction Of Feature Lines On Surface Meshes Based On Discrete Morse Theory
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We present an approach for extracting extremal feature lines of scalar indicators on surface meshes, based on discrete Morse Theory. By computing initial Morse-Smale complexes of the scalar indicators of the mesh, we obtain ... -
A Four-level Focus + Context Approach to Interactive Visual Analysis of Temporal Features in Large Scientific Data
(The Eurographics Association and Blackwell Publishing Ltd., 2008)In this paper we present a new approach to the interactive visual analysis of time-dependent scientific data - both from measurements as well as from computational simulation - by visualizing a scalar function over time ... -
FromWeb Data to Visualization via Ontology Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2008)In this paper, we propose a novel approach for automatic generation of visualizations from domain-specific data available on the web. We describe a general system pipeline that combines ontology mapping and probabilistic ... -
Generating Color Palettes using Intuitive Parameters
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Color is widely used in data visualization to show data values. The proper selection of colors is critical to convey information correctly. In this paper, we present a technique for generating univariate lightness ordered ... -
Geometry-driven Visualization of Microscopic Structures in Biology
(The Eurographics Association and Blackwell Publishing Ltd., 2008)At a microscopic resolution, biological structures are composed of cells, red blood corpuscles (RBCs), cytoplasm and other microstructural components. There is a natural pattern in terms of distribution, arrangement and ... -
GPU Local Triangulation: an Interpolating Surface Reconstruction Algorithm
(The Eurographics Association and Blackwell Publishing Ltd., 2008)A GPU capable method for surface reconstruction from unorganized point clouds without additional information, called GLT (GPU Local Triangulation), is presented. The main objective of this research is the generation of a ... -
Illustrative Hybrid Visualization and Exploration of Anatomical and Functional Brain Data
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Common practice in brain research and brain surgery involves the multi-modal acquisition of brain anatomy and brain activation data. These highly complex three-dimensional data have to be displayed simultaneously in order ... -
Illustrative Parallel Coordinates
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Illustrative parallel coordinates (IPC) is a suite of artistic rendering techniques for augmenting and improving parallel coordinate (PC) visualizations. IPC techniques can be used to convey a large amount of information ... -
Interaction-Dependent Semantics for Illustrative Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2008)In traditional illustration the choice of appropriate styles and rendering techniques is guided by the intention of the artist. For illustrative volume visualizations it is difficult to specify the mapping between the 3D ... -
Interactive Exploratory Visualization of 2D Vector Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2008)In this paper we present several techniques to interactively explore representations of 2D vector fields. Through a set of simple hand postures used on large, touch-sensitive displays, our approach allows individuals to ... -
Interactive Visualization for Memory Reference Traces
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We present the Memory Trace Visualizer (MTV), a tool that provides interactive visualization and analysis of the sequence of memory operations performed by a program as it runs. As improvements in processor performance ... -
Interactive Visualization of Multimodal Volume Data for Neurosurgical Tumor Treatment
(The Eurographics Association and Blackwell Publishing Ltd., 2008)We present novel interactive methods for the visualization of multimodal volume data as used in neurosurgical therapy planning. These methods allow surgeons to explore multimodal volumes and focus on functional data and ... -
Investigative Visual Analysis of Global Terrorism
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Recent increases in terrorist activity around the world have made analyzing and understanding such activities more critical than ever. With the help of organizations such as the National Center for the Study of Terrorism ... -
Lagrangian Visualization of Flow-Embedded Surface Structures
(The Eurographics Association and Blackwell Publishing Ltd., 2008)The notions of Finite-Time Lyapunov Exponent (FTLE) and Lagrangian Coherent Structures provide a strong framework for the analysis and visualization of complex technical flows. Their definition is simple and intuitive, and ... -
Navigation and Exploration of Interconnected Pathways
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Visualizing pathways, i. e. models of cellular functional networks, is a challenging task in computer assisted biomedicine. Pathways are represented as large collections of interwoven graphs, with complex structures present ... -
Particle Level Set Advection for the Interactive Visualization of Unsteady 3D Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Typically, flow volumes are visualized by defining their boundary as iso-surface of a level set function. Grid-based level sets offer a good global representation but suffer from numerical diffusion of surface detail, ... -
Physically-based Dye Advection for Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2008)Dye advection is widely used in experimental flow analysis but has seen less use for visualization in computational fluid dynamics. One possible reason for this disconnect is the inaccuracy of the texture-based approach, ... -
