  • An Interpolation Scheme for VDVP Lagrangian Basis Flows 

    Sane, Sudhanshu; Childs, Hank; Bujack, Roxana (The Eurographics Association, 2019)
    Using the Eulerian paradigm, accurate flow visualization of 3D time-varying data requires a high temporal resolution resulting in large storage requirements. The Lagrangian paradigm has proven to be a viable in situ-based ...
  • Hybrid Remote Visualization in Immersive Virtual Environments with Vistle 

    Aumüller, Martin (The Eurographics Association, 2019)
    Because of the spatial separation of high performance compute resources and immersive visualization systems, their combined use requires remote visualization. Remote rendering incurs increased latency from user interaction ...
  • Statistical Analysis of Parallel Data Uploading using OpenGL 

    Wiedemann, Markus; Kranzlmüller, Dieter (The Eurographics Association, 2019)
    Modern real-time visualizations of large-scale datasets require constant high frame rates while their datasets might exceed the available graphics memory. This requires sophisticated upload strategies from host memory to ...
  • Efficient Point Merging Using Data Parallel Techniques 

    Yenpure, Abhishek; Childs, Hank; Moreland, Kenneth (The Eurographics Association, 2019)
    We study the problem of merging three-dimensional points that are nearby or coincident. We introduce a fast, efficient approach that uses data parallel techniques for execution in various shared-memory environments. Our ...
  • Screen Partitioning Load Balancing for Parallel Rendering on a Multi-GPU Multi-Display Workstation 

    Dong, Yangzi; Peng, Chao (The Eurographics Association, 2019)
    Commodity workstations with multiple GPUs have been built by engineers and scientists for real-time rendering applications. As a result, a high display resolution can be achieved by connecting each GPU to a display monitor ...
  • Hybrid Online Autotuning for Parallel Ray Tracing 

    Herveau, Killian; Pfaffe, Philip; Tillmann, Martin Peter; Tichy, Walter F.; Dachsbacher, Carsten (The Eurographics Association, 2019)
    Acceleration structures are key to high performance parallel ray tracing. Maximizing performance requires configuring the degrees of freedom (e.g., construction parameters) these data structures expose. Whether a parameter ...
  • Real-time Particle-based Snow Simulation on the GPU 

    Goswami, Prashant; Markowicz, Christian; Hassan, Ali (The Eurographics Association, 2019)
    This paper presents a novel real-time particle-based method for simulating snow on the GPU. Our method captures compression and bonding between snow particles, and incorporates the thermodynamics to model the realistic ...
  • Parallel XPBD Simulation of Modified Morse Potential - an Alternative Spring Model 

    Cetinaslan, Ozan (The Eurographics Association, 2019)
    In this paper, we introduce a modified Morse potential as an alternative to the existing spring models within a massively parallel extended Position Based Dynamics (XPBD) algorithm. To date, stretching is one of the most ...
  • Task-based Augmented Reeb Graphs with Dynamic ST-Trees 

    Gueunet, Charles; Fortin, Pierre; Jomier, Julien; Tierny, Julien (The Eurographics Association, 2019)
    This paper presents, to the best of our knowledge, the first parallel algorithm for the computation of the augmented Reeb graph of piecewise linear scalar data. Such augmented Reeb graphs have a wide range of applications, ...
  • Scalable Parallel Flow Visualization Using 3D Line Integral Convolution for Large Scale Unstructured Simulation Data 

    Liao, Yangguang; Matsui, Hiroaki; Kreylos, Oliver; Kellogg, Louise H. (The Eurographics Association, 2019)
    To address the need of highly efficient and scalable parallel flow visualization methods, we developed a flow visualization system for large unstructured simulation data using parallel 3D line integral convolution (LIC). ...
  • PGV 2019: Frontmatter 

    Childs, Hank; Frey, Steffen (The Eurographics Association, 2019)
  • Fast Mesh Validation in Combustion Simulations through In-Situ Visualization 

    Shudler, Sergei; Ferrier, Nicola; Insley, Joseph; Papka, Michael E.; Patel, Saumil; Rizzi, Silvio (The Eurographics Association, 2019)
    In-situ visualization and analysis is a powerful concept that aims to give users the ability to process data while it is still resident in memory, thereby vastly reducing the amount of data left for post-hoc analysis. The ...
  • Dynamic I/O Budget Reallocation For In Situ Wavelet Compression 

    Marsaglia, Nicole J.; Li, Shaomeng; Belcher, Kristi; Larsen, Matthew; Childs, Hank (The Eurographics Association, 2019)
    In situ wavelet compression is a potential solution for enabling post hoc visualization on supercomputers with slow I/O systems. While this in situ compression is typically accomplished by allocating an equal storage budget ...
  • 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 ...
