      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 ...
    • Design and Evaluation of a GPU Streaming Framework for Visualizing Time-Varying AMR Data 

      Zellmann, Stefan; Wald, Ingo; Sahistan, Alper; Hellmann, Matthias; Usher, Will (The Eurographics Association, 2022)
      We describe a systematic approach for rendering time-varying simulation data produced by exa-scale simulations, using GPU workstations. The data sets we focus on use adaptive mesh refinement (AMR) to overcome memory bandwidth ...
    • Design and Implementation of A Large-scale Hybrid Distributed Graphics System 

      Yang, Jian; Shi, Jiaoying; Jin, Zhefan; Zhang, Hui (The Eurographics Association, 2002)
      Although modern graphics hardware has strong capability to render millions of triangles within a second, huge scenes are still unable to be rendered in real-time. Lots of parallel and distributed graphics systems are ...
    • 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 ...
    • Direct Send Compositing for Parallel Sort-Last Rendering 

      Eilemann, Stefan; Pajarola, Renato (The Eurographics Association, 2007)
      In contrast to sort-first, sort-last parallel rendering has the distinct advantage that the task division for parallel geometry processing and rasterization is simple, and can easily be incorporated into most visualization ...
    • Distributed Collaborative Data Analysis with Heterogeneous Visualisation Systems 

      Duessel, Thomas; Zilken, Herwig; Frings, W.; Eickermann, T.; Gerndt, A.; Wolter, Marc; Kuhlen, Torsten (The Eurographics Association, 2007)

    • Distributed Force-Directed Graph Layout and Visualization 

      Mueller, Christopher; Gregor, Douglas; Lumsdaine, Andrew (The Eurographics Association, 2006)
      While there exist many interactive tools for the visualization of small graphs and networks, these tools do not address the fundamental problems associated with the visualization of large graphs. In particular, larger ...
    • Distributed OpenGL Rendering in Network Bandwidth Constrained Environments 

      Neal, Braden; Hunkin, Paul; McGregor, Antony (The Eurographics Association, 2011)
      Display walls made from multiple monitors are often used when very high resolution images are required. To utilise a display wall, rendering information must be sent to each computer that the monitors are connect to. The ...
