Lossless Geometry Compression for Steady-State and Time-Varying Irregular Grids
(The Eurographics Association, 2006)In this paper we investigate the problem of lossless geometry compression of irregular-grid volume data represented as a tetrahedral mesh. We propose a novel lossless compression technique that effectively predicts, models, ... -
Multiresolution Interblock Interpolation in Direct Volume Rendering
(The Eurographics Association, 2006)We present a direct interblock interpolation technique that enables direct volume rendering of blocked, multiresolution volumes. The proposed method smoothly interpolates between blocks of arbitrary block-wise level-of-detail ... -
Natural Visualizations
(The Eurographics Association, 2006)This paper demonstrates the prevalence of a shared characteristic between visualizations and images of nature. We have analyzed visualization competitions and user studies of visualizations and found that the more preferred, ... -
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 ... -
Perspective Isosurface and Direct Volume Rendering for Virtual Endoscopy Applications
(The Eurographics Association, 2006)Virtual endoscopy has proven to be a very powerful tool in endoscopic surgery. However, most virtual endoscopy systems are restricted to rendering isosurfaces or require segmentation in order to visualize additional objects ... -
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 ... -
PointCloudXplore: Visual Analysis of 3D Gene Expression Data Using Physical Views and Parallel Coordinates
(The Eurographics Association, 2006)To allow a more rigorous understanding of animal gene regulatory networks, the Berkeley Drosophila Transcription Network Project (BDTNP) has developed a suite of methods that support quantitative, computational analysis ... -
Real-Time Super Resolution Contextual Close-up of Clinical Volumetric Data
(The Eurographics Association, 2006)We present an illustrative visualization system for real-time and high quality rendering of clinical volumetric medical data. Our technique is inspired by a medical illustration technique for depicting contextual close-up ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
