    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • EGPGV 2018: Frontmatter 

      Childs, Hank; Cucchietti, Fernando (The Eurographics Association, 2018)
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
