    • Comparative Visualization and Analysis of Time-Dependent, 2D Foam Simulation Data 

      Lipsa, Dan R.; Laramee, Robert S.; Cox, Simon; Davies, I. Tudur (The Eurographics Association, 2014)
      Liquid foams have important practical applications. To analyze the dependence of foam behavior on material properties, and to improve foam models, foam scientists work with dozens of related simulations obtained by varying ...

    • Fast and Simple Agglomerative LBVH Construction 

      Apetrei, Ciprian (The Eurographics Association, 2014)
      This paper continues the long-standing tradition of gradually improving the construction speed of spatial acceleration structures using sorted Morton codes. Previous work on this topic forms a clear sequence where each new ...

    • Gap-Sensitive Segmentation and Restoration of Digital Images 

      Sobiecki, Andre; Jalba, Andrei; Boda, Daniel; Diaconeasa, Adriana; Telea, Alexandru (The Eurographics Association, 2014)
      Many methods exist for removing defects such as gaps, cracks, and disconnections from digital shapes. However, most such methods have several limitations, such as removing both erroneous and important shape details, or ...

    • Geological Orientation Measurements using an iPad: Method Comparison 

      Hama, Layik; Ruddle, Roy A.; Paton, Douglas (The Eurographics Association, 2014)
      This paper describes a tablet-based application to be used by novice geologists for taking geological measurements during fieldwork. The application was implemented on an iPad2. Both our app and the FieldMove Clino iOS app ...

    • Modelling of Clouds from a Hemispherical Image 

      Alldieck, Thiemo; Lundtoft, Dennis H.; Montanari, Niels; Nikolov, Ivan; Vlaykov, Iskren G.; Madsen, Claus B. (The Eurographics Association, 2014)
      This paper presents an image-based method for modelling clouds. Unlike previous image-based approaches, a hemispherical photograph is used as input, enabling to consider an entire sky instead of merely a portion. Our method ...

    • A Study on Glyph-based Visualisation with Dense Visual Context 

      Khan, Saiful; Proctor, Karl J.; Walton, Simon; Bañares-Alcántara, René; Chen, Min (The Eurographics Association, 2014)
      In a focus+context visualization, one often finds it difficult to overlay focus information on top of a dense visual context. This work is motivated by a need for visualizing search results (i.e., focus) in relation to a ...

    • Variations on Image Reconstruction:Weighted Back Projection and Fourier Expectation Maximization 

      Ryan, Andrew; Mora, B. (The Eurographics Association, 2014)
      Expectation Maximization and Filtered Back Projection are two common techniques for Tomographic reconstruction of images and volumes. While papers often demonstrat that EM produces higher quality reconstructions, particularly ...

    • Visual Analysis of Hurricane Data Using Joint Contour Net 

      Geng, Zhao; Duke, David; Carr, Hamish; Chattopadhyay, Amit (The Eurographics Association, 2014)
      Topology provides a rigorous foundation for identifying features and transitions within data. However, computing and presenting topological features in multi-dimensional range space is still a difficult problem. The Joint ...
