    • Self-Scheduled Parallel Isosurfacing using Distributed Span Space on Cell 

      Caruso, Michael R.; Newman, Timothy S. (The Eurographics Association, 2010)
      A method designed for fast isosurfacing on Cell platforms is introduced. It well-utilizes limited amounts of local memory by exploiting a block-based span space. Exploitation goes beyond the usual steps of avoiding span ...
    • Scalable Parallel Out-of-core Terrain Rendering 

      Goswami, Prashant; Makhinya, Maxim; Bösch, Jonas; Pajarola, Renato (The Eurographics Association, 2010)
      In this paper, we introduce a novel out-of-core parallel and scalable technique for rendering massive terrain datasets. The parallel rendering task decomposition is implemented on top of an existing terrain renderer using ...
    • Towards a Software Transactional Memory for Graphics Processors 

      Cederman, Daniel; Tsigas, Philippas; Chaudhry, Muhammad Tayyab (The Eurographics Association, 2010)
      The introduction of general purpose computing on many-core graphics processor systems, and the general shift in the industry towards parallelism, has created a demand for ease of parallelization. Software transactional ...
    • Cross-Node Occlusion in Sort-Last Volume Rendering 

      Marchesin, Stéphane; Ma, Kwan-Liu (The Eurographics Association, 2010)
      In the field of parallel volume rendering, occlusion is a concept which is already widely exploited in order to improve performance. However, when one moves to larger datasets the use of parallelism becomes a necessity, ...
    • Load-Balanced Isosurfacing on Multi-GPU Clusters 

      Martin, Steven; Shen, Han-Wei; McCormick, Patrick (The Eurographics Association, 2010)
      Isosurface extraction is a common technique applied in scientific visualization. Increasing sizes of volumes over which isosurfacing is to be applied combined with increasingly hierarchical parallel architectures present ...
    • Accelerating and Benchmarking Radix-k Image Compositing at Large Scale 

      Kendall, Wesley; Peterka, Tom; Huang, Jian; Shen, Han-Wei; Ross, Robert (The Eurographics Association, 2010)
      Radix-k was introduced in 2009 as a configurable image compositing algorithm. The ability to tune it by selecting k-values allows it to benefit more from pixel reduction and compression optimizations than its predecessors. ...
    • Asynchronous Parallel Reliefboard Computation for Scene Object Approximation 

      Süß, Tim; Jähn, Claudius; Fischer, Matthias (The Eurographics Association, 2010)
      We present a parallel algorithm for the rendering of complex three-dimensional scenes. The algorithm runs across heterogeneous architectures of PC-clusters consisting of a visualization-node, equipped with a powerful ...
    • Streamed Ray Tracing of Single Rays on the Cell Processor 

      Bingel, Florian; Hinkenjann, Andre (The Eurographics Association, 2010)
      In this paper we present an approach to efficiently trace single rays on the Cell Processor, instead of using ray packets. To benefit from the performance of this processor, a data structure is chosen which allows traversal ...
    • PaTraCo: A Framework Enabling the Transparent and Efficient Programming of Heterogeneous Compute Networks 

      Frey, Steffen; Ertl, Thomas (The Eurographics Association, 2010)
      We propose PaTraCo (Parallel Transparent Computation), a framework for developing parallel applications for single host or ad-hoc compute network environments incorporating a multitude of different kinds of compute devices ...
    • Cache-Efficient Parallel Isosurface Extraction for Shared Cache Multicores 

      Tchiboukdjian, Marc; Danjean, Vincent; Raffin, Bruno (The Eurographics Association, 2010)
      This paper proposes to revisit isosurface extraction algorithms taking into consideration two specific aspects of recent multicore architectures: their intrinsic parallelism associated with the presence of multiple computing ...
    • Parallel View-Dependent Refinement of Compact Progressive Meshes 

      Derzapf, Evgenij; Menzel, Nicolas; Guthe, Michael (The Eurographics Association, 2010)
      The complexity of polygonal models still grows faster than the ability of the graphics hardware to render them in real-time. A common way to deal with such models is to use multiple levels of detail (LODs). These can be ...
    • MPI-hybrid Parallelism for Volume Rendering on Large, Multi-core Systems 

      Howison, Mark; Bethel, E. Wes; Childs, Hank (The Eurographics Association, 2010)
      This work studies the performance and scalability characteristics of hybrid parallel programming and execution as applied to raycasting volume rendering a staple visualization algorithm on a large, multi-core platform. ...
    • Fast Compositing for Cluster-Parallel Rendering 

      Makhinya, Maxim; Eilemann, Stefan; Pajarola, Renato (The Eurographics Association, 2010)
      The image compositing stages in cluster-parallel rendering for gathering and combining partial rendering results into a final display frame are fundamentally limited by node-to-node image throughput. Therefore, efficient ...
    • Multi-Frame Rate Volume Rendering 

      Hauswiesner, Stefan; Kalkofen, Denis; Schmalstieg, Dieter (The Eurographics Association, 2010)
      This paper presents multi-frame rate volume rendering, an asynchronous approach to parallel volume rendering. The workload is distributed over multiple GPUs in such a way that the main display device can provide high frame ...
    • Ray Tracing Dynamic Scenes with Shadows on the GPU 

      Guntury, Sashidhar; Narayanan, P. J. (The Eurographics Association, 2010)
      We present fast ray tracing of dynamic scenes in this paper with primary and shadow rays. We present a GPUfriendly strategy to bring coherency to shadow rays, based on previous work on grids as acceleration structures. We ...
