  • High-Quality Rendering of Glyphs Using Hardware-Accelerated Ray Tracing 

    Zellmann, Stefan; Aumüller, Martin; Marshak, Nathan; Wald, Ingo (The Eurographics Association, 2020)
    Glyph rendering is an important scientific visualization technique for 3D, time-varying simulation data and for higherdimensional data in general. Though conceptually simple, there are several different challenges when ...
  • Alternative Parameters for On-The-Fly Simplification of MergeTrees 

    Werner, Kilian; Garth, Christoph (The Eurographics Association, 2020)
    Topological simplification of merge trees requires a user specified persistence threshold. As this threshold is based on prior domain knowledge and has an unpredictable relation to output size, its use faces challenges in ...
  • Approaches for In Situ Computation of Moments in a Data-Parallel Environment 

    Tsai, Karen C.; Bujack, Roxana; Geveci, Berk; Ayachit, Utkarsh; Ahrens, James (The Eurographics Association, 2020)
    Feature-driven in situ data reduction can overcome the I/O bottleneck that large simulations face in modern supercomputer architectures in a semantically meaningful way. In this work, we make use of pattern detection as a ...
  • Improving Performance of M-to-N Processing and Data Redistribution in In Transit Analysis and Visualization 

    Loring, Burlen; Wolf, Mathew; Kress, James; Shudler, Sergei; Gu, Junmin; Rizzi, Silvio; Logan, Jeremy; Ferrier, Nicola; Bethel, E. Wes (The Eurographics Association, 2020)
    In an in transit setting, a parallel data producer, such as a numerical simulation, runs on one set of ranks M, while a data consumer, such as a parallel visualization application, runs on a different set of ranks N: One ...
  • Effective Parallelization Strategies for Scalable, High-Performance Iterative Reconstruction 

    Gribble, Christiaan Paul (The Eurographics Association, 2020)
    Iterative reconstruction techniques in X-ray computed tomography converge to a result by successively refining increasingly accurate estimates. Compared to alternative approaches, iterative reconstruction imposes significant ...
  • Moment-Based Opacity Optimization 

    Zeidan, Mahmoud; Rapp, Tobias; Peters, Christoph; Dachsbacher, Carsten (The Eurographics Association, 2020)
    Geometric structures such as points, lines, and surfaces play a vital role in scientific visualization. However, these visualizations frequently suffer from visual clutter that hinders the inspection of important features ...
  • Fast Multi-View Rendering for Real-Time Applications 

    Unterguggenberger, Johannes; Kerbl, Bernhard; Steinberger, Markus; Schmalstieg, Dieter; Wimmer, Michael (The Eurographics Association, 2020)
    Efficient rendering of multiple views can be a critical performance factor for real-time rendering applications. Generating more than one view multiplies the amount of rendered geometry, which can cause a huge performance ...
  • Finding Efficient Spatial Distributions for Massively Instanced 3-d Models 

    Zellmann, Stefan; Morrical, Nate; Wald, Ingo; Pascucci, Valerio (The Eurographics Association, 2020)
    Instancing is commonly used to reduce the memory footprint of massive 3-d models. Nevertheless, large production assets often do not fit into the memory allocated to a single rendering node or into the video memory of a ...
  • PGV 2020: Frontmatter 

    Frey, Steffen; Huang, Jian; Sadlo, Filip (The Eurographics Association, 2020)
  • 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 ...
