    • Evonne: A Visual Tool for Explaining Reasoning with OWL Ontologies and Supporting Interactive Debugging 

      Méndez, J.; Alrabbaa, C.; Koopmann, P.; Langner, R.; Baader, F.; Dachselt, R. (© 2023 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2023)
      OWL is a powerful language to formalize terminologies in an ontology. Its main strength lies in its foundation on description logics, allowing systems to automatically deduce implicit information through logical reasoning. ...
    • Exact and Error-bounded Approximate Color Buffer Compression and Decompression 

      Rasmusson, Jim; Hasselgren, Jon; Akenine-Moeller, Tomas (The Eurographics Association, 2007)
      In this paper, we first present a survey of existing color buffer compression algorithms. After that, we introduce a new scheme based on an exactly reversible color transform, simple prediction, and Golomb-Rice encoding. ...
    • Exact and Robust (Self-)Intersections for Polygonal Meshes 

      Campen, Marcel; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We present a new technique to implement operators that modify the topology of polygonal meshes at intersections and self-intersections. Depending on the modification strategy, this effectively results in operators for ...
    • Exact Computation of the Hausdorff Distance between Triangular Meshes 

      Straub, Raphael (The Eurographics Association, 2007)
      We present an algorithm that computes the exact Hausdorff distance between two arbitrary triangular meshes. Our method computes squared distances for each point on each triangle of one mesh to all relevant triangles of the ...
    • Exact Constraint Satisfaction for Truly Seamless Parametrization 

      Mandad, Manish; Campen, Marcel (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      In the field of global surface parametrization a recent focus has been on so-called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of ...
    • Exact From-Region Visibility Culling 

      Nirenstein, S.; Blake, E.; Gain, J. (The Eurographics Association, 2002)
      To pre-process a scene for the purpose of visibility culling during walkthroughs it is necessary to solve visibility from all the elements of a finite partition of viewpoint space. Many conservative and approximate solutions ...
    • An Exact Incremental Hidden Surface RemovalAlgorithm 

      Kuijk, A.A.M.; Hagen, P.J. W. ten; Akman, V. (The Eurographics Association, 1987)
      This paper describes an incremental Hidden Surface Removal Algorithm (HSRA), developed to be embedded in a new architecture for raster graphics described in [1,7]. The algorithm can be classified as "exact" since it operates ...
    • Exact Isosurfaces for Marching Cubes 

      Theisel, Holger (Blackwell Publishers Ltd and the Eurographics Association, 2002)
      In this paper we study the exact contours of a piecewise trilinear scalar field. We show how to represent these contours exactly as trimmed surfaces of triangular rational cubic Bezier patches. As part of this, we introduce ...
    • Exact volume preserving skinning with shape control 

      Rohmer, Damien; Hahmann, Stefanie; Cani, Marie-Paule (ACM SIGGRAPH / Eurographics Association, 2009)
      In the real world, most objects do not loose volume when they deform: they may for instance compensate a local compression by inflating in the orthogonal direction, or, in the case of a character, preserve volume through ...
    • Exaggerating Character Motions Using Sub-Joint Hierarchy 

      Kwon, Ji-yong; Lee, In-Kwon (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Motion capture cannot generate cartoon-style animation directly. We emulate the rubber-like exaggerations common in traditional character animation as a means of converting motion capture data into cartoon-like movement. ...
    • Examining Design-Centric Test Participants in Graphical Perception Experiments 

      Guo, Grace; Dy, Bianchi; Ibrahim, Nazim; Joyce, Sam Conrad; Poorthuis, Ate (The Eurographics Association, 2020)
      In this paper, we replicate a foundational study in graphical perception, and compare our findings from using design-centric participants with that of previous studies. We also assess the visual accuracy of two groups, ...
    • Examining Implicit Discretization in Spectral Schemes 

      Quinan, P. Samuel; Padilla, Lace M. K.; Creem-Regehr, Sarah H.; Meyer, Miriah (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Two of the primary reasons rainbow color maps are considered ineffective trace back to the idea that they implicitly discretize encoded data into hue-based bands, yet no research addresses what this discretization looks ...
    • Examining the Components of Trust in Map-Based Visualizations 

      Xiong, Cindy; Padilla, Lace; Grayson, Kent; Franconeri, Steven (The Eurographics Association, 2019)
      Prior research suggests that perceived transparency is often associated with perceived trust. For some data types, greater transparency in data visualization is also associated with an increase in the amount of information ...
    • Example Based Repetitive Structure Synthesis 

      Roveri, Riccardo; Öztireli, A. Cengiz; Martin, Sebastian; Solenthaler, Barbara; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present an example based geometry synthesis approach for generating general repetitive structures. Our model is based on a meshless representation, unifying and extending previous synthesis methods. Structures in the ...
    • Example-Based 3D Scan Completion 

      Pauly, Mark; Mitra, Niloy J.; Giesen, Joachim; Gross, Markus; Guibas, Leonidas J. (The Eurographics Association, 2005)
      We present a novel approach for obtaining a complete and consistent 3D model representation from incomplete surface scans, using a database of 3D shapes to provide geometric priors for regions of missing data. Our method ...
    • An Example-Based Approach for Facial Expression Cloning 

      Pyun, Hyewon; Kim, Yejin; Chae, Wonseok; Kang, Hyung Woo; Shin, Sung Yong (The Eurographics Association, 2003)
      In this paper, we present a novel example-based approach for cloning facial expressions of a source model to a target model while reflecting the characteristic features of the target model in the resulting animation. Our ...
