    • Analysis of Cache Behavior and Performance of Different BVH Memory Layouts for Tracing Incoherent Rays 

      Wodniok, Dominik; Schulz, Andre; Widmer, Sven; Goesele, Michael (The Eurographics Association, 2013)
      With CPUs moving towards many-core architectures and GPUs becoming more general purpose architectures, path tracing can now be well parallelized on commodity hardware. While parallelization is trivial in theory, properties ...

    • GPU Acceleration of Particle Advection Workloads in a Parallel, Distributed Memory Setting 

      Camp, David; Krishnan, Hari; Pugmire, David; Garth, Christoph; Johnson, Ian; Bethel, E. Wes; Joy, Kenneth I.; Childs, Hank (The Eurographics Association, 2013)
      Although there has been significant research in GPU acceleration, both of parallel simulation codes (i.e., GPGPU) and of single GPU visualization and analysis algorithms, there has been relatively little research devoted ...

    • Image-parallel Ray Tracing using OpenGL Interception 

      Brownlee, Carson; Ize, Thiago; Hansen, Charles D. (The Eurographics Association, 2013)
      CPU Ray tracing in scientific visualization has been shown to be an efficient rendering algorithm for large-scale polygonal data on distributed-memory systems by using custom integrations which modify the source code of ...

    • In Situ Pathtube Visualization with Explorable Images 

      Ye, Yucong; Miller, Robert; Ma, Kwan-Liu (The Eurographics Association, 2013)
      In situ processing is considered to be the most plausible data analysis and visualization solution for extreme-scale simulations. Explorable images were introduced as an in situ visualization method to enable interactive ...

    • Practical Parallel Rendering of Detailed Neuron Simulations 

      Hernando, Juan B.; Biddiscombe, John; Bohara, Bidur; Eilemann, Stefan; Schürmann, Felix (The Eurographics Association, 2013)
      Parallel rendering of large polygonal models with transparency is challenging due to the need for alpha-correct blending and compositing, which is costly for very large models with high depth complexity and spatial overlap. ...

    • Rendering Molecular Surfaces using Order-Independent Transparency 

      Kauker, Daniel; Krone, Michael; Panagiotidis, Alexandros; Reina, Guido; Ertl, Thomas (The Eurographics Association, 2013)
      In this paper we present a technique for interactively rendering transparent molecular surfaces. We use Puxels, our implementation of per-pixel linked lists for order-independent transparency rendering. Furthermore, we ...

    • Scalable Parallel Feature Extraction and Tracking for Large Time-varying 3D Volume Data 

      Wang, Yang; Yu, Hongfeng; Ma, Kwan-Liu (The Eurographics Association, 2013)
      Large-scale time-varying volume data sets can take terabytes to petabytes of storage space to store and process. One promising approach is to process the data in parallel, and then extract and analyze only features of ...

    • Scalable Seams for Gigapixel Panoramas 

      Philip, Sujin; Summa, Brian; Tierny, Julien; Bremer, Peer-Timo; Pascucci, Valerio (The Eurographics Association, 2013)
      Gigapixel panoramas are an increasingly popular digital image application. They are often created as a mosaic of smaller images composited into a larger single image. The mosaic acquisition can occur over many hours causing ...

    • VtkSMP: Task-based Parallel Operators for VTK Filters 

      Ettinger, Mathias; Broquedis, F.; Gautier, T.; Ploix, S.; Raffin, Bruno (The Eurographics Association, 2013)
      NUMA nodes are potentially powerful but taking benefit of their capabilities is challenging due to their architecture (multiple computing cores, advanced memory hierarchy). They are nonetheless one of the key components ...
