  • Functional Maps on Product Manifolds 

    Rodolà, Emanuele; Lähner, Zorah; Bronstein, Alex M.; Bronstein, Michael M.; Solomon, Justin (The Eurographics Association, 2018)
    We consider the tasks of representing, analyzing and manipulating maps between shapes. We model maps as densities over the product manifold of the input shapes; these densities can be treated as scalar functions and therefore ...
  • Solving PDEs on Deconstructed Domains 

    Sellán, Silvia; Cheng, Herng Yi; Ma, Yuming; Dembowski, Mitchell; Jacobson, Alec (The Eurographics Association, 2018)
    When finding analytical solutions to Partial Differential Equations (PDEs) becomes impossible, it is useful to approximate them via a discrete mesh of the domain. Sometimes a robust triangular (2D) or tetrahedral (3D) mesh ...
  • Denoising of Point-clouds Based on Structured Dictionary Learning 

    Sarkar, Kripasindhu; Bernard, Florian; Varanasi, Kiran; Theobalt, Christian; Stricker, Didier (The Eurographics Association, 2018)
    We formulate the problem of point-cloud denoising in terms of a dictionary learning framework over square surface patches. Assuming that many of the local patches (in the unknown noise-free point-cloud) contain redundancies ...
  • Using Mathematical Morphology to Simplify Archaeological Fracture Surfaces 

    ElNaghy, Hanan; Dorst, Leo (The Eurographics Association, 2018)
    It is computationally expensive to fit the high-resolution 3D meshes of abraded fragments of archaeological artefacts in a collection. Therefore, simplification of fracture surfaces while preserving the fitting essentials ...
  • Out-of-core Resampling of Gigantic Point Clouds 

    Bletterer, Arnaud; Payan, Frédéric; Antonini, Marc; Meftah, Anis (The Eurographics Association, 2018)
    Nowadays, LiDAR scanners are able to capture complex scenes of real life, leading to extremely detailed point clouds. However, the amount of points acquired (several billions) and their distribution raise the problem of ...
  • Frontmatter: Symposium on Geometry Processing 2018 - Posters 

    Ju, Tao; Vaxman, Amir (The Eurographics Association, 2018)
  • La VALSE: Scalable Log Visualization for Fault Characterization in Supercomputers 

    Guo, Hanqi; Di, Sheng; Gupta, Rinku; Peterka, Tom; Cappello, Franck (The Eurographics Association, 2018)
    We design and implement La VALSE-a scalable visualization tool to explore tens of millions of records of reliability, availability, and serviceability (RAS) logs-for IBM Blue Gene/Q systems. Our tool is designed to meet ...
  • Interactive Visual Analysis of Multi-dimensional Metamodels 

    Gebhardt, Sascha; Pick, Sebastian; Hentschel, Bernd; Kuhlen, Torsten Wolfgang (The Eurographics Association, 2018)
    In the simulation of manufacturing processes, complex models are used to examine process properties. To save computation time, so-called metamodels serve as surrogates for the original models. Metamodels are inherently ...
  • Rapid k-d Tree Construction for Sparse Volume Data 

    Zellmann, Stefan; Schulze, Jürgen P.; Lang, Ulrich (The Eurographics Association, 2018)
    While k-d trees are known to be effective for spatial indexing of sparse 3-D volume data, full reconstruction, e.g. due to changes to the alpha transfer function during rendering, is usually a costly operation with this ...
  • Revisiting the Evaluation of In Situ Lagrangian Analysis 

    Sane, Sudhanshu; Bujack, Roxana; Childs, Hank (The Eurographics Association, 2018)
    In situ usage of Lagrangian techniques has proven to be superior with respect to emerging supercomputing trends than the traditional Eulerian approach for scientific flow analysis. However, previous studies have not informed ...
  • Dense Texture Flow Visualization using Data-Parallel Primitives 

    Kim, Mark; Klasky, Scott; Pugmire, David (The Eurographics Association, 2018)
    Recent trends in supercomputing towards massively threaded on-node processors to increase performance has also introduced fragmented software support. In response to this changing landscape, new scientific visualization ...
  • Performance-Portable Particle Advection with VTK-m 

    Pugmire, David; Yenpure, Abhishek; Kim, Mark; Kress, James; Maynard, Robert; Childs, Hank; Hentschel, Bernd (The Eurographics Association, 2018)
    Particle advection is the fundamental kernel behind most vector field visualization methods. Yet, the efficient parallel computation of large amounts of particle traces remains challenging. This is exacerbated by the variety ...
  • Robust Iterative Find-Next-Hit Ray Traversal 

    Wald, Ingo; Amstutz, Jefferson; Benthin, Carsten (The Eurographics Association, 2018)
    We present two different methods for improving the performance and robustness of ray tracing algorithms that require iterating through multiple successive intersections along the same ray. Our methods do so without ever ...
  • Hardware-Accelerated Multi-Tile Streaming for Realtime Remote Visualization 

    Biedert, Tim; Messmer, Peter; Fogal, Thomas; Garth, Christoph (The Eurographics Association, 2018)
    The physical separation of compute resource and end user is one of the core challenges in HPC visualization. While GPUs are routinely used in remote rendering, a heretofore unexplored aspect is these GPUs' special purpose ...
  • VisIt-OSPRay: Toward an Exascale Volume Visualization System 

    Wu, Qi; Usher, Will; Petruzza, Steve; Kumar, Sidharth; Wang, Feng; Wald, Ingo; Pascucci, Valerio; Hansen, Charles D. (The Eurographics Association, 2018)
    Large-scale simulations can easily produce data in excess of what can be efficiently visualized using production visualization software, making it challenging for scientists to gain insights from the results of these ...
  • Direct Raytracing of Particle-based Fluid Surfaces Using Anisotropic Kernels 

    Biedert, Tim; Sohns, Jan-Tobias; Schröder, Simon; Amstutz, Jefferson; Wald, Ingo; Garth, Christoph (The Eurographics Association, 2018)
    Particle-based simulation models have assumed a significant role in the numerical computation of high-fidelity transient flow and continuum mechanical problems. However, direct visualization of surfaces from particle data ...

    Childs, Hank; Cucchietti, Fernando (The Eurographics Association, 2018)
  • Performing Image-like Convolution on Triangular Meshes 

    Tortorici, Claudio; Werghi, Naoufel; Berretti, Stefano (The Eurographics Association, 2018)
    Image convolution with a filtering mask is at the base of several image analysis operations. This is motivated by Mathematical foundations and by the straightforward way the discrete convolution can be computed on a grid-like ...
  • Experimental Similarity Assessment for a Collection of Fragmented Artifacts 

    Biasotti, Silvia; Thompson, Elia Moscoso; Spagnuolo, Michela (The Eurographics Association, 2018)
    In the Visual Heritage domain, search engines are expected to support archaeologists and curators to address cross-correlation and searching across multiple collections. Archaeological excavations return artifacts that ...
  • Completion of Cultural Heritage Objects with Rotational Symmetry 

    Sipiran, Ivan (The Eurographics Association, 2018)
    Archaeological artifacts are an important part of our cultural heritage. They help us understand how our ancestors used to live. Unfortunately, many of these objects are badly damaged by the passage of time and need repair. ...
