Adaptive Volume Construction from Ultrasound Images of a Human Heart
(The Eurographics Association, 2004)We present a volume modelling approach based on sequences of two-dimensional ultrasound images. Though generally applicable to arbitrary freehand ultrasound, our method is designed for the reconstruction of timevarying ... -
Auralization I: Vortex Sound Synthesis
(The Eurographics Association, 2004)Auralization is the process of extracting and displaying meaningful information in the form of sound from data. Through not only visualization but also auralization, users may have better understandings of the data, ... -
A Botanically Inspired High-Dimensional Visualization with Multivariate Glyphs
(The Eurographics Association, 2004)It is difficult for the average viewer to assimilate and comprehend huge amounts of high-dimensional data. It is important to present data in a way that allows the user a high level understanding of the overall organization ... -
Boundary Switch Connectors for Topological Visualization of Complex 3D Vector Fields
(The Eurographics Association, 2004)One of the reasons that topological methods have a limited popularity for the visualization of complex 3D flow fields is the fact that their topological structures contain a number of separating stream surfaces. Since these ... -
Browsing and Visualizing Digital Bibliographic Data
(The Eurographics Association, 2004)Access to publications is provided by conventional libraries, digital libraries operated by learned societies or commercial publishers, and a huge number of web sites maintained by the scientists themselves or their ... -
Case Study: Visual Analysis of Complex, Time-Dependent Simulation Results of a Diesel Exhaust System
(The Eurographics Association, 2004)In previous work we have presented visualization techniques that provide engineers with a high degree of interactivity and flexibility for analyzing large, time-dependent, and high-dimensional data sets resulting from CFD ... -
Case Study: Visualization of annotated DNA sequences
(The Eurographics Association, 2004)DNA sequences and their annotations form ever expanding data sets. Proper explorations of such data sets require new tools for visualization and analysis. In this case study, we have defined the requirements for a visualization ... -
A Cluster-Space Visual Interface for Arbitrary Dimensional Classification of Volume Data
(The Eurographics Association, 2004)In volume visualization, users typically specify transfer functions to classify the data and assign visual attributes to each material class. Higher-dimensional classification makes it easier to differentiate material ... -
DTI Visualization with Streamsurfaces and Evenly-Spaced Volume Seeding
(The Eurographics Association, 2004)Experimental evidence has shown that water diffusion is anisotropic in organized tissues such as white matter or muscles. Diffusion Tensor Imaging is a non-invasive MR technique that measures water diffusion. DTI is used ... -
Efficient Display of Background Objects for Virtual Endoscopy using Flexible First-Hit Ray Casting
(The Eurographics Association, 2004)Many applications of virtual endoscopy require the display of background objects behind the semi-transparent surface of the investigated organ. This paper deals with pre-processing and visualization of background objects ... -
Efficient Isosurface Tracking Using Precomputed Correspondence Table
(The Eurographics Association, 2004)Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ... -
Efficient Isosurface Tracking Using Precomputed Correspondence Table
(The Eurographics Association, 2004)Feature tracking is a useful method for visualizing and analyzing time-varying scalar fields. It allows scientists to focus on regions of interest and track their evolution and interaction over time. To allow the user to ... -
Generalized Distance Transforms and Skeletons in Graphics Hardware
(The Eurographics Association, 2004)We present a framework for computing generalized distance transforms and skeletons of two-dimensional objects using graphics hardware. Our method is based on the concept of footprint splatting. Combining different splats ... -
Graph Drawing by Subspace Optimization
(The Eurographics Association, 2004)We show a novel approach for accelerating the computation of graph drawing algorithms. The method is based on the notion that we can find a subspace with a relatively low dimensionality that captures the "nice" layouts of ... -
High-Quality Lighting and Efficient Pre-Integration for Volume Rendering
(The Eurographics Association, 2004)Pre-integrated volume rendering is an effective technique for generating high-quality visualizations. The precomputed lookup tables used by this method are slow to compute and can not include truly pre-integrated lighting ... -
Illustrating Surfaces in Volume
(The Eurographics Association, 2004)This paper presents a novel framework for illustrating surfaces in a volume. Surfaces are illustrated by drawing only feature lines, such as silhouettes, valleys, ridges, and surface hatching strokes, and are embedded in ... -
Interaction Spaces in Data and Information Visualization
(The Eurographics Association, 2004)User interaction plays an integral part in the effective visualization of data and information. Typical interaction operations include navigation, selection, and distortion. A problem that can occur when these operations ... -
Interactive High Quality Trimmed NURBS Visualization Using Appearance Preserving Tessellation
(The Eurographics Association, 2004)Trimmed NURBS models are the standard representation used in CAD/CAM systems and accurate visualization of large trimmed NURBS models at interactive frame rates is of great interest for industry. To visualize the quality ... -
Interactive TreemapsWith Detail on Demand to Support Information Search in Documents
(The Eurographics Association, 2004)This paper addresses the issue of how information visualization techniques can be used to assist full-text search in electronic documents. Our approach supports multiple term queries with interactive treemaps. We use a ... -
Interactively Visualizing Procedurally Encoded Scalar Fields
(The Eurographics Association, 2004)While interactive visualization of rectilinear gridded volume data sets can now be accomplished using texture mapping hardware on commodity PCs, interactive rendering and exploration of large scattered or unstructured data ...
