    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 ...
  • 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 ...
  • Multi-GPU Image-based Visual Hull Rendering 

    Hauswiesner, Stefan; Khlebnikov, Rostislav; Steinberger, Markus; Straka, Matthias; Reitmayr, Gerhard (The Eurographics Association, 2012)
    Many virtual mirror and telepresence applications require novel viewpoint synthesis with little latency to user motion. Image-based visual hull (IBVH) rendering is capable of rendering arbitrary views from segmented images ...
  • 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 ...
  • Parallel Rendering on Hybrid Multi-GPU Clusters 

    Eilemann, Stefan; Bilgili, Ahmet; Abdellah, Marwan; Hernando, Juan; Makhinya, Maxim; Pajarola, Renato; Schürmann, Felix (The Eurographics Association, 2012)
    Achieving efficient scalable parallel rendering for interactive visualization applications on medium-sized graphics clusters remains a challenging problem. Framerates of up to 60hz require a carefully designed and fine-tuned ...
  • Light Propagation Maps on Parallel Graphics Architectures 

    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 ...
  • Polygonization of Implicit Surfaces on Multi-Core Architectures with SIMD Instructions 

    Shirazian, Pourya; Wyvill, Brian; Duprat, Jean-Luc (The Eurographics Association, 2012)
    In this research we tackle the problem of rendering complex models which are created using implicit primitives, blending operators, affine transformations and constructive solid geometry in a design environment that organizes ...
  • 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 ...
  • 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. ...
  • Explicit Cache Management for Volume Ray-Casting on Parallel Architectures 

    Jönsson, Daniel; Ganestam, Per; Doggett, Michael; Ynnerman, Anders; Ropinski, Timo (The Eurographics Association, 2012)
    A major challenge when designing general purpose graphics hardware is to allow efficient access to texture data. Although different rendering paradigms vary with respect to their data access patterns, there is no flexibility ...
  • A Study of Ray Tracing Large-scale Scientific Data in Two Widely Used Parallel Visualization Applications 

    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 ...
