    • 3D Strokes on Visible Structures in Direct Volume Rendering 

      Wiebel, Alexander; Preis, Philipp; Vos, Frans M.; Hege, Hans-Christian (The Eurographics Association, 2013)
      In this paper we describe VisiTrace, a novel technique to draw 3D lines in direct volume rendered images. It allows to draw strokes in the 2D space of the screen to produce 3D lines that run on top or in the center of ...
    • Accelerated Volume Rendering with Volume Guided Neural Denoising

      Monte Carlo path tracing techniques create stunning visualizations of volumetric data. However, a large number of computationally expensive light paths are required for each sample to produce a smooth and noise-free image, ...
    • Additional On-Demand Dimension for Data Visualization 

      Hube, Natalie; Müller, Mathias; Groh, Rainer (The Eurographics Association, 2017)
      In this paper, we present a concept to interactively extend an 2d visualization by an additional on-demand dimension. We use categorical data in a multidimensional information space applied in a travel search scenario. ...
    • Algorithmic Improvements on Hilbert and Moore Treemaps for Visualization of Large Tree-structured Datasets 

      Scheibel, Willy; Weyand, Christopher; Bethge, Joseph; Döllner, Jürgen (The Eurographics Association, 2021)
      Hilbert and Moore treemaps are based on the same named space-filling curves to lay out tree-structured data for visualization. One main component of them is a partitioning subroutine, whose algorithmic complexity poses ...
    • Ambient Grids: Maintain Context-Awareness via Aggregated Off-Screen Visualization 

      Jäckle, Dominik; Stoffel, Florian; Kwon, Bum Chul; Sacha, Dominik; Stoffel, Andreas; Keim, Daniel A. (The Eurographics Association, 2015)
      When exploring large spatial datasets, zooming and panning interactions often lead to the loss of contextual overview. Existing overview-plus-detail approaches allow users to view context while inspecting details, but they ...
    • Analysis of Error in Interpolation-Based Pathline Tracing 

      Chandler, Jennifer; Bujack, Roxana; Joy, Kenneth I. (The Eurographics Association, 2016)
      Chandler et al. [COJ15] presented interpolation-based pathline tracing as an alternative to numerical integration for advecting tracers in particle-based flow fields and showed that their method has lower error than a ...
    • Analytic Behavior and Trust Building in Visual Analytics 

      Sacha, Dominik; Boesecke, Ina; Fuchs, Johannes; Keim, Daniel A. (The Eurographics Association, 2016)
      Visual Analytics (VA) is a collaborative process between human and computer, where analysts are performing numerous interactions and reasoning activities. This paper presents our current progress in developing a note taking ...
    • Analytic Ray Splitting for Controlled Precision DVR 

      Weiss, Sebastian; Westermann, Rüdiger (The Eurographics Association, 2021)
      For direct volume rendering of post-classified data, we propose an algorithm that analytically splits a ray through a cubical cell at the control points of a piecewise-polynomial transfer function. This splitting generates ...
    • Analyzing the Evolution of the Internet 

      Johnson, Thienne; Acedo, Carlos; Kobourov, Stephen; Nusrat, Sabrina (The Eurographics Association, 2015)
      Existing representations of the Internet do not provide information on why countries have a bigger Internet presence (e.g., Internet Service Providers) than others. In this paper we evaluate four geo-economic parameters ...
    • Application-oriented Analysis of Material Interface Reconstruction Algorithms in Time-varying Bijel Simulations 

      Bao, Xueyi; Karthikeyan, Nikhil; Schiller, Ulf D.; Iuricich, Federico (The Eurographics Association, 2022)
      Multimaterial interface reconstruction has been investigated over the years both from visualization and analytical point of view using different metrics. When focusing on visualization, interface continuity and smoothness ...
    • arcs.fm - A Backdrop Visualization for Music Talk 

      Baur, Dominikus; Butz, Andreas; Carpendale, Sheelagh (The Eurographics Association, 2012)
      Visualizations usually completely capture our attention or disappear into the ambient background. In this paper we explore a middle ground, with visualizations that are not constantly in the center of attention and support ...
    • An Argument Structure for Data Stories 

      Kosara, Robert (The Eurographics Association, 2017)
      Many data stories in journalism do not have a story arc, but rather present facts without much structure. This mirrors the popular inverted pyramid style of writing that presents the most important information up front, ...
    • ARGUS: Interactive Visual Analytics Framework for the Discovery of Disruptions in Bio-Behavioral Rhythms 

      Mansoor, Hamid; Gerych, Walter; Buquicchio, Luke; Alajaji, Abdulaziz; Chandrasekaran, Kavin; Agu, Emmanuel; Rundensteiner, Elke (The Eurographics Association, 2020)
      Human Bio-Behavioral Rhythms (HBRs) such as sleep-wake cycles and their regularity have important health ramifications. Smartphones can sense HBRs by gathering and analyzing data from built-in sensors, which provide ...
    • ARrow: A Real-Time AR Rowing Coach 

      Iannucci, Elena; Chen, Zhutian; Armeni, Iro; Pollefeys, Marc; Pfister, Hanspeter; Beyer, Johanna (The Eurographics Association, 2023)
      Rowing requires physical strength and endurance in athletes as well as a precise rowing technique. The ideal rowing stroke is based on biomechanical principles and typically takes years to master. Except for time-consuming ...
    • Ask and You Shall Receive (a Graph Drawing): Testing ChatGPT's Potential to Apply Graph Layout Algorithms 

      Bartolomeo, Sara Di; Severi, Giorgio; Schetinger, Victor; Dunne, Cody (The Eurographics Association, 2023)
      Large language models (LLMs) have recently taken the world by storm. They can generate coherent text, hold meaningful conversations, and be taught concepts and basic sets of instructions-such as the steps of an algorithm. ...
