      Brownlee, Carson; Patchett, John; Lo, Li-Ta; DeMarle, David; Mitchell, Christopher; Ahrens, James; Hansen, Charles D. (The Eurographics Association, 2012)
      Large-scale analysis and visualization is becoming increasingly important as supercomputers and their simulations produce larger and larger data. These large data sizes are pushing the limits of traditional rendering ...
    • Auto Splats: Dynamic Point Cloud Visualization on the GPU 

      Preiner, Reinhold; Jeschke, Stefan; Wimmer, Michael (The Eurographics Association, 2012)
      Capturing real-world objects with laser-scanning technology has become an everyday task. Recently, the acquisition of dynamic scenes at interactive frame rates has become feasible. A high-quality visualization of the ...
    • EAVL: The Extreme-scale Analysis and Visualization Library 

      Meredith, Jeremy S.; Ahern, Sean; Pugmire, Dave; Sisneros, Robert (The Eurographics Association, 2012)
      Analysis and visualization of the data generated by scientific simulation codes is a key step in enabling science from computation. However, a number of challenges lie along the current hardware and software paths to ...
    • GLuRay: Enhanced Ray Tracing in Existing Scientific Visualization Applications using OpenGL Interception 

      Brownlee, Carson; Fogal, Thomas; Hansen, Charles D. (The Eurographics Association, 2012)
      Ray tracing in scientific visualization allows for substantial gains in performance and rendering quality with large scale polygonal datasets compared to brute-force rasterization, however implementing new rendering ar- ...
    • Load-Balanced Multi-GPU Ambient Occlusion for Direct Volume Rendering 

      Ancel, Alexandre; Dischler, Jean-Michel; Mongenet, Catherine (The Eurographics Association, 2012)
      Ambient occlusion techniques were introduced to improve data comprehension by bringing soft fading shadows to the visualization of 3D datasets. They consist in attenuating light by considering the occlusion resulting from ...
    • HyperFlow: A Heterogeneous Dataflow Architecture 

      Vo, Huy T.; Osmari, Daniel K.; Comba, João; Lindstrom, Peter; Silva, Cláudio T. (The Eurographics Association, 2012)
      We propose a dataflow architecture, called HyperFlow, that offers a supporting infrastructure that creates an abstraction layer over computation resources and naturally exposes heterogeneous computation to dataflow processing. ...
    • Dynamic Scheduling for Large-Scale Distributed-Memory Ray Tracing 

      Navrátil, Paul A.; Fussell, Donald S.; Lin, Calvin; Childs, Hank (The Eurographics Association, 2012)
      Ray tracing is an attractive technique for visualizing scientific data because it can produce high quality images that faithfully represent physically-based phenomena. Its embarrassingly parallel reputation makes it a ...
    • Shift-Based Parallel Image Compositing on InfiniBand TM Fat-Trees 

      Cavin, Xavier; Demengeon, Olivier (The Eurographics Association, 2012)
      Parallel image compositing has been widely studied over the past 20 years, as this is one, if not the most, crucial element in the implementation of a scalable parallel rendering system. Many algorithms have been proposed ...
    • Fast Collision Culling in Large-Scale Environments Using GPU Mapping Function 

      Avril, Quentin; Gouranton, Valérie; Arnaldi, Bruno (The Eurographics Association, 2012)
      This paper presents a novel and efficient GPU-based parallel algorithm to cull non-colliding object pairs in very large-scale dynamic simulations. It allows to cull objects in less than 25ms with more than 100K objects. ...

      Gruson, Adrien; Patil, Ajit Hakke; Cozot, Remi; Bouatouch, Kadi; Pattanaik, Sumanta (The Eurographics Association, 2012)
      Light going through a participating medium like smoke can be scattered or absorbed by every point in the medium. To accurately render such a medium we must compute the radiance resulting at every point inside the medium ...
    • Time-constrained Animation Rendering on Desktop Grids 

      Aggarwal, Vibhor; Debattista, Kurt; Bashford-Rogers, Thomas; Chalmers, Alan (The Eurographics Association, 2012)
