    • Memory-Efficient On-The-Fly Voxelization of Particle Data 

      Zirr, Tobias; Dachsbacher, Carsten (The Eurographics Association, 2015)
      In this paper we present a novel GPU-friendly real-time voxelization technique for rendering homogeneous media that is defined by particles, e.g. fluids obtained from particle-based simulations such as Smoothed Particle ...

    • Visualizing Groundwater Flow Through Karst Limestone 

      Knoll, Aaron; Brownlee, Carson; Navrátil, Paul; Cunningham, Kevin J.; Sukop, Michael C.; Garcia, Sadé (The Eurographics Association, 2015)
      Water management is critical in Florida where freshwater is often rare or, in times of flooding, overabundant and seawater frequently contaminates available sources. Professor Michael Sukop from Florida International ...

    • Visualization of High-Resolution Weather Model Data 

      Liu, Si; Foss, Greg; Abram, Greg; Bowen, Anne (The Eurographics Association, 2015)
      Significant bottlenecks from I/O required novel techniques be used for a high-resolution severe weather simulation and visualization in the region centered around O'Hare International Airport. The Raytheon Company collaborated ...

    • Visualization of 2DWave Propagation by Huygens' Principle 

      Heßel, Stefan; Fernandes, Oliver; Boblest, Sebastian; Offenhäuser, Philipp; Hoffmann, Malte; Beck, Andrea; Ertl, Thomas; Glass, Colin; Munz, Claus-Dieter; Sadlo, Filip (The Eurographics Association, 2015)
      We present a novel technique to visualize wave propagation in 2D scalar fields. Direct visualization of wave fronts is susceptible to visual clutter and interpretation difficulties due to space-time interference and global ...

    • Volume Rendering Via Data-Parallel Primitives 

      Larsen, Matthew; Labasan, Stephanie; Navrátil, Paul; Meredith, Jeremy; Childs, Hank (The Eurographics Association, 2015)
      Supercomputing designs have recently evolved to include architectures beyond the standard CPU. In response, visualization software must be developed in a manner that obviates the need for porting all visualization algorithms ...

    • TOD-Tree: Task-Overlapped Direct send Tree Image Compositing for Hybrid MPI Parallelism 

      Grosset, A. V. Pascal; Prasad, Manasa; Christensen, Cameron; Knoll, Aaron; Hansen, Charles (The Eurographics Association, 2015)
      Modern supercomputers have very powerful multi-core CPUs. The programming model on these supercomputer is switching from pure MPI to MPI for inter-node communication, and shared memory and threads for intra-node communication. ...

    • Large-Scale Parallel Visualization of Particle-Based Simulations using Point Sprites and Level-Of-Detail 

      Rizzi, Silvio; Hereld, Mark; Insley, Joseph; Papka, Michael E.; Uram, Thomas; Vishwanath, Venkatram (The Eurographics Association, 2015)
      Recent large-scale particle-based simulations are generating vast amounts of data posing a challenge to visualization algorithms. One possibility for addressing this challenge is to map particles into a regular grid for ...

    • Frontmatter: EG PGV 2015 - Eurographics Symposium on Parallel Graphics and Visualization 

      Dachsbacher, Carsten; Navrátil, Paul (Eurographics Association, 2015)

    • Contour Tree Depth Images For Large Data Visualization 

      Biedert, Tim; Garth, Christoph (The Eurographics Association, 2015)
      High-fidelity simulation models on large-scale parallel computer systems can produce data at high computational throughput, but modern architectural trade-offs make full persistent storage to the slow I/O subsystem ...

    • Out-of-Core Framework for QEM-based Mesh Simplification 

      Ozaki, Hiromu; Kyota, Fumihito; Kanai, Takashi (The Eurographics Association, 2015)
      In mesh simplification, in-core based methods using Quadric Error Metric (QEM), which apply a sequence of edge-collapse operations, can generate high-quality meshes while preserving shape features. However, these methods ...

    • Packet-Oriented Streamline Tracing on Modern SIMD Architectures 

      Hentschel, Bernd; Göbbert, Jens Henrik; Klemm, Michael; Springer, Paul; Schnorr, Andrea; Kuhlen, Torsten W. (The Eurographics Association, 2015)
      The advection of integral lines is an important computational kernel in vector field visualization. We investigate how this kernel can profit from vector (SIMD) extensions in modern CPUs. As a baseline, we formulate a ...

    • SIMD Parallel Ray Tracing of Homogeneous Polyhedral Grids 

      Rathke, Brad; Wald, Ingo; Chiu, Kenneth; Brownlee, Carson (The Eurographics Association, 2015)
      Efficient visualization of unstructured data is vital for domain scientists, yet is often impeded by techniques which rely on intermediate representations that consume time and memory, require resampling data, or inefficient ...

    • Visualization Showcase: General-Relativistic Black Hole Visualization 

      Müller, Thomas; Boblest, Sebastian; Weiskopf, Daniel (The Eurographics Association, 2015)
      Black holes are among the most fascinating and weird objects in the universe. They distort space and time in their close neighborhood in a way that is far beyond our every day experience. We demonstrate the visual effects ...
