Galilean Invariant Extraction and Iconic Representation of Vortex Core Lines
(The Eurographics Association, 2005)While vortex region quantities are Galilean invariant, most methods for extracting vortex cores depend on the frame of reference. We present an approach to extracting vortex core lines independently of the frame of reference ... -
A Gaze-enabled Graph Visualization to Improve Graph Reading Tasks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Performing typical network tasks such as node scanning and path tracing can be difficult in large and dense graphs. To alleviate this problem we use eye-tracking as an interactive input to detect tasks that users intend ... -
GEMSe: Visualization-Guided Exploration of Multi-channel Segmentation Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present GEMSe, an interactive tool for exploring and analyzing the parameter space of multi-channel segmentation algorithms. Our targeted user group are domain experts who are not necessarily segmentation specialists. ... -
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 ... -
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 ... -
A Generic Solution for Hardware-Accelerated Remote Visualization
(The Eurographics Association, 2002)This paper presents a generic solution for hardware-accelerated remote visualization that works transparently for all OpenGL-based applications and OpenGL-based scene graphs. Universality is achieved by taking advantage ... -
Geodesic Flow on Polyhedral Surfaces
(Springer and The Eurographics Association, 1999)On a curved surface the front of a point wave evolves in concentric circles which start to overlap and branch after a certain time. This evolution is described by the geodesic flow and helps us to understand the geometry ... -
Geometric Methods for Vortex Extraction
(Springer and The Eurographics Association, 1999)This paper presents two vortex detection methods which are based on the geometric properties of streamlines. Unlike traditional vortex detection methods, which are based on point-samples of physical quantities, one of our ... -
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 ... -
Gestaltlines
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a general technique to visualize multivariate data sequences. It is based on a symbiotic combination of three powerful concepts from information visualization: sparklines, glyphs and gestalt theory. By visualizing ... -
Glyphs for Asymmetric Second-Order 2D Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Tensors model a wide range of physical phenomena. While symmetric tensors are sufficient for some applications (such as diffusion), asymmetric tensors are required, for example, to describe differential properties of fluid ... -
Glyphs for Exploring Crowd-sourced Subjective Survey Classification
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The findings drawn from opinion survey responses are usually made by producing summary charts or conducting statistical analysis. Both involve data aggregation and filtering as exploring the unaggregated data has traditionally ... -
The Gödel Engine - An Interactive Approach to Visualization in General Relativity
(The Eurographics Association and Blackwell Publishing Ltd., 2009)We present a methodical new approach to visualize the aspects of general relativity from a self-centered perspective. We focus on the visualization of the Gödel universe, which is an exact solution to Einstein s field ... -
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 ... -
GPU-Accelerated Volume Splatting With Elliptical RBFs
(The Eurographics Association, 2006)Radial Basis Functions (RBFs) have become a popular rendering primitive, both in surface and in volume rendering. This paper focuses on volume visualization, giving rise to 3D kernels. RBFs are especially convenient for ... -
GPU-Based Hyperstreamlines for Diffusion Tensor Imaging
(The Eurographics Association, 2006)We propose a new approach for the visualization of hyperstreamlines, which offers potential for better scalability than the conventional polygon-based approach. Our method circumvents the bandwidth bottleneck between the ... -
GPUFLIC: Interactive and Accurate Dense Visualization of Unsteady Flows
(The Eurographics Association, 2006)The paper presents an efficient and accurate implementation of Unsteady Flow LIC (UFLIC) on the Graphics Processing Unit (GPU). We obtain the same, high quality texture representation of unsteady two-dimensional flows as ... -
A Gradient-Based Comparison Measure for Visual analysis of Multifield Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We introduce a multifield comparison measure for scalar fields that helps in studying relations between them. The comparison measure is insensitive to noise in the scalar fields and to noise in their gradients. Further, ... -
A Granular Three Dimensional Multiresolution Transform
(The Eurographics Association, 2006)We propose a three dimensional multi-resolution scheme to represent volumetric data in resolutions which are powers of two, resolving the rigidity of the commonly used separable Cartesian multi-resolution schemes in 3D ... -
Graph Bundling by Kernel Density Estimation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a fast and simple method to compute bundled layouts of general graphs. For this, we first transform a given graph drawing into a density map using kernel density estimation. Next, we apply an image sharpening ...
