    • The Natural 3D Spiral 

      Harary, Gur; Tal, Ayellet (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Logarithmic spirals are ubiquitous in nature. This paper presents a novel mathematical definition of a 3D logarithmic spiral, which provides a proper description of objects found in nature. To motivate our work, we scanned ...

    • Illustrative Visualization of a Vortex Breakdown Bubble 

      Hummel, Mathias; Garth, Christoph; Hamann, Bernd; Hagan, Hans; Joy, Kenneth I. (The Eurographics Association and Blackwell Publishing Ltd., 2011)

    • Review: Kd-tree Traversal Algorithms for Ray Tracing 

      Hapala, M.; Havran, V. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper we review the traversal algorithms for kd-trees for ray tracing. Ordinary traversal algorithms such as sequential, recursive, and those with neighbour-links have different limitations, which led to several ...

    • Bertin was Right: An Empirical Evaluation of Indexing to Compare Multivariate Time-Series Data Using Line Plots 

      Aigner, W.; Kainz, C.; Ma, R.; Miksch, S. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Line plots are very well suited for visually representing time-series. However, several difficulties arise when multivariate heterogeneous time-series data is displayed and compared visually. Especially, if the developments ...

    • Eurographics 2010 Workshop on 3D Object Retrieval (EG 3DOR’10) in cooperation with ACM SIGGRAPH 

      Daoudi, Mohamed; Schreck, Tobias (The Eurographics Association and Blackwell Publishing Ltd., 2011)

    • Allometric Scaling for Character Design 

      McGraw, T.; Kawai, T.; Richards, J. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Geometric scaling transformations do not respect the biological processes which govern the size and shape of living creatures. In this paper, we describe an approach to scaling which can be related to biological function. ...

    • A Survey of Real-Time Hard Shadow Mapping Methods 

      Scherzer, Daniel; Wimmer, Michael; Purgathofer, Werner (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Because of its versatility, speed and robustness, shadow mapping has always been a popular algorithm for fast hard shadow generation since its introduction in 1978, first for offline film productions and later increasingly ...

    • Compact Models 

      Coll, Narcís; Paradinas, Teresa (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Development of approximation techniques for highly detailed surfaces is one of the challenges faced today. We introduce a new mesh structure that allows dense triangular meshes of arbitrary topology to be approximated. The ...

    • On Neighbourhood Matching for Texture-by-Numbers 

      Sivaks, Eliyahu; Lischinski, Dani (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Texture-by-Numbers is an attractive texture synthesis framework, because it is able to cope with non-homogeneous texture exemplars, and provides the user with intuitive creative control over the outcome of the synthesis ...

    • Taylor Prediction for Mesh Geometry Compression 

      Courbet, Clément; Hudelot, Céline (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      In this paper, we introduce a new formalism for mesh geometry prediction. We derive a class of smooth linear predictors from a simple approach based on the Taylor expansion of the mesh geometry function. We use this method ...

    • CheckViz: Sanity Check and Topological Clues for Linear and Non-Linear Mappings 

      Lespinats, Sylvain; Aupetit, Michaël (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Multidimensional scaling is a must-have tool for visual data miners, projecting multidimensional data onto a two-dimensional plane. However, what we see is not necessarily what we think about. In many cases, end-users do ...

    • Using VisTrails and Provenance for Teaching Scientific Visualization 

      Silva, Cláudio T.; Anderson, Erik; Santos, Emanuele; Freire, Juliana (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Over the last 20 years, visualization courses have been developed and offered at universities around the world. Many of these courses use established visualization libraries and tools (e.g. VTK, ParaView, AVS, VisIt) as a ...

    • Free Path Sampling in High Resolution Inhomogeneous Participating Media 

      Szirmay-Kalos, László; Tóth, Balázs; Magdics, Milán (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents efficient algorithms for free path sampling in heterogeneous participating media defined either by high-resolution voxel arrays or generated procedurally. The method is based on the concept of mixing ...

    • A Parallel SPH Implementation on Multi-Core CPUs 

      Ihmsen, Markus; Akinci, Nadir; Becker, Markus; Teschner, Matthias (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      This paper presents a parallel framework for simulating fluids with the Smoothed Particle Hydrodynamics (SPH) method. For low computational costs per simulation step, efficient parallel neighbourhood queries are proposed ...

    • Experimental Feedback on Prog and Play: A Serious Game for Programming Practice
