Kelp Diagrams: Point Set Membership Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present Kelp Diagrams, a novel method to depict set relations over points, i.e., elements with predefined positions. Our method creates schematic drawings and has been designed to take aesthetic quality, efficiency, and ... -
KeyStrokes: Personalizing Typed Text with Visualization
(The Eurographics Association, 2007)With the ubiquity of typed text, the style and much of the personality of handwriting has been lost from general communication. To counter this we introduce an artistic real-time visualization of typed messages that ... -
Knowledge-Based Out-of-Core Algorithms for Data Management in Visualization
(The Eurographics Association, 2006)Data management is the very first issue in handling very large datasets. Many existing out-of-core algorithms used in visualization are closely coupled with application-specific logic. This paper presents two knowledgebased ... -
Lagrangian Coherent Structures with Guaranteed Material Separation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Given an unsteady flow field, one common way to compute Lagrangian Coherent Structures (LCS) is to extract extremal structures of the Finite Time Lyapunov Exponent (FTLE). Experience has shown that the resulting structures ... -
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 ... -
Learning Probabilistic Transfer Functions: A Comparative Study of Classifiers
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Complex volume rendering tasks require high-dimensional transfer functions, which are notoriously difficult to design. One solution to this is to learn transfer functions from scribbles that the user places in the volumetric ... -
Lifted Domain Coloring
(The Eurographics Association and Blackwell Publishing Ltd., 2009)Complex-valued functions are fundamental objects in complex analysis, algebra, differential geometry and in many other areas such as numerical mathematics and physics. Visualizing complex functions is a non-trivial task ... -
Line Integral Convolution for Real-Time Illustration of Molecular Surface Shape and Salient Regions
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel line drawing algorithm that illustrates surfaces in real-time to convey their shape. We use line integral convolution (LIC) and employ ambient occlusion for illustrative surface rendering. Furthermore, ... -
Localized Flow Analysis of 2D and 3D Vector Fields
(The Eurographics Association, 2005)In this paper we present an approach to the analysis of the contribution of a small subregion in a dataset to the global flow. To this purpose, we subtract the potential flow that is induced by the boundary of the sub-domain ... -
Locating Closed Streamlines in 3D Vector Fields
(The Eurographics Association, 2002)The analysis and visualization of flows is a central problem in visualization. Topology based methods have gained increasing interest in recent years. This article describes a method for the detection of closed streamlines ... -
Location-dependent Generalization of Road Networks Based on Equivalent Destinations
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Suppose a user located at a certain vertex in a road network wants to plan a route using a wayfinding map. The user's exact destination may be irrelevant for planning most of the route, because many destinations will be ... -
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, ... -
LoVis: Local Pattern Visualization for Model Refinement
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Linear models are commonly used to identify trends in data. While it is an easy task to build linear models using pre-selected variables, it is challenging to select the best variables from a large number of alternatives. ... -
Lyra: An Interactive Visualization Design Environment
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present Lyra, an interactive environment for designing customized visualizations without writing code. Using drag-and-drop interactions, designers can bind data to the properties of graphical marks to author expressive ... -
Magnetic Flux Topology of 2D Point Dipoles
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Magnetic fields exhibit higher-order, nonlinear singularities in the form of point-dipole singularities. In addition, due to absence of divergence, they feature only a subset of invariant structures from traditional vector ... -
Mail Explorer - Spatial and Temporal Exploration of Electronic Mail
(The Eurographics Association, 2005)In today s world, e-mail has become one of the most important means of communication in business and private lives due to its efficiency. However, the problems start as soon as mail volumes go beyond the scope of human ... -
Mandatory Critical Points of 2D Uncertain Scalar Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper introduces a novel, non-local characterization of critical points and their global relation in 2D uncertain scalar fields. The characterization is based on the analysis of the support of the probability density ... -
Manual Clustering Refinement using Interaction with Blobs
(The Eurographics Association, 2007)The huge amount of different automatic clustering methods emphasizes one thing: there is no optimal clustering method for all possible cases. In certain application domains, like genomics and natural language processing, ... -
Many Plans: Multidimensional Ensembles for Visual Decision Support in Flood Management
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Uncertainties in flood predictions complicate the planning of mitigation measures. There is a consensus that many possible incident scenarios should be considered. For each scenario, a specific response plan should be ... -
Map-based Visualizations Increase Recall Accuracy of Data
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We investigate the memorability of data represented in two different visualization designs. In contrast to recent studies that examine which types of visual information make visualizations memorable, we examine the effect ...
