The i-Disc - A Tool To Visualize and Explore Topic Maps
(The Eurographics Association, 2005)We present the i-Disc, a tool to interactively visualize and explore medium sized topic maps. Topic maps contain two basic structures: the topic hierarchy and the associations between topics. Our system presents the topic ... -
I-SI: Scalable Architecture of Analyzing Latent Topical-Level Information From Social Media Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a general visual analytics architecture that is designed and implemented to effectively analyze unstructured social media data on a large scale. Pipelined on a high-performance cluster configuration, MPI processing, ... -
I/O-Conscious Volume Rendering
(The Eurographics Association, 2001)Most existing volume rendering algorithms assume that data sets are memory-resident and thus ignore the performance overhead of disk I/O. While this assumption may be true for high-performance graphics machines, it does ... -
Illuminated 3D Scatterplots
(The Eurographics Association and Blackwell Publishing Ltd., 2009)In contrast to 2D scatterplots, the existing 3D variants have the advantage of showing one additional data dimension, but suffer from inadequate spatial and shape perception and therefore are not well suited to display ... -
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 ... -
Illustrative Context-Preserving Volume Rendering
(The Eurographics Association, 2005)In volume rendering it is very difficult to simultaneously visualize interior and exterior structures while preserving clear shape cues. Very transparent transfer functions produce cluttered images with many overlapping ... -
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 Membrane Clipping
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Clipping is a fast, common technique for resolving occlusions. It only requires simple interaction, is easily understandable, and thus has been very popular for volume exploration. However, a drawback of clipping is that ... -
Illustrative Molecular Visualization with Continuous Abstraction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Molecular systems may be visualized with various degrees of structural abstraction, support of spatial perception, and 'illustrativeness.' In this work we propose and realize methods to create seamless transformations that ... -
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 ... -
Illustrative Visualization of Molecular Reactions using Omniscient Intelligence and Passive Agents
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper we propose a new type of a particle systems, tailored for illustrative visualization purposes, in particular for visualizing molecular reactions in biological networks. Previous visualizations of biochemical ... -
Illustrative White Matter Fiber Bundles
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Diffusion Tensor Imaging (DTI) has made feasible the visualization of the fibrous structure of the brain white matter. In the last decades, several fiber-tracking methods have been developed to reconstruct the fiber tracts ... -
Image-Based Edge Bundles: Simplified Visualization of Large Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2010)We present a new approach aimed at understanding the structure of connections in edge-bundling layouts. We combine the advantages of edge bundles with a bundle-centric simplified visual representation of a graph s structure. ... -
imMens: Real-time Visual Querying of Big Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Data analysts must make sense of increasingly large data sets, sometimes with billions or more records.We present methods for interactive visualization of big data, following the principle that perceptual and interactive ... -
Importance Driven Automatic Color Design for Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)This paper introduces an automatic color design method that is driven by an importance function of the objects within a volumetric dataset. Our method allows the user to intuitively modify the object classification and the ... -
ImPrEd: An Improved Force-Directed Algorithm that Prevents Nodes from Crossing Edges
(The Eurographics Association and Blackwell Publishing Ltd., 2011)PrEd [Ber00] is a force-directed algorithm that improves the existing layout of a graph while preserving its edge crossing properties. The algorithm has a number of applications including: improving the layouts of planar ... -
Improved visualization in virtual colonoscopy using image-based rendering
(The Eurographics Association, 2001)Virtual colonoscopy (VC) is a patient-friendly alternative for colorectal endoscopic examination. We explore visualization aspects of VC such as surface in view, navigation and communication of a diagnosis. A series of ... -
Improving Angular Resolution in Visualizations of Geographic Networks
(The Eurographics Association, 2000)In visualizations of large-scale transportation and communications networks, node coordinates are usually fixed to preserve the underlying geography, while links are represented as geodesics for simplicity. This often leads ... -
Improving the Quality of Multi-resolution Volume Rendering
(The Eurographics Association, 2006)We propose a novel method to improve the quality of multi-resolution visualizations. We reduce aliasing artifacts by approximating the data distribution with a Gaussian basis function at each level of detail for more ... -
Improving Topological Segmentation of Three-dimensional Vector Fields
(The Eurographics Association, 2003)We present three enhancements to accelerate the extraction of separatrices of three-dimensional vector fields, using intelligently selected "sample" streamlines. These enhancements reduce the number of needed sample ...
