      Müller, C.; Strengert, M.; Ertl, T. (The Eurographics Association, 2006)
      In this paper, we present a sort-last parallel volume rendering system based on single-pass volume raycasting performed in the fragment shader unit. The architecture is aimed for displaying data sets that utilize the total ...

    • 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 ...

    • An Out-of-core Method for Computing Connectivities of Large Unstructured Meshes 

      Ueng, Shyh-Kuang; Sikorski, K. (The Eurographics Association, 2002)
      Adjacency graphs of meshes are important for visualizing or compressing unstructured scientific data. However, calculating adjacency graphs requires intensive memory space. For large data sets, the calculation becomes very ...

    • Out-Of-Core Sort-First Parallel Rendering for Cluster-Based Tiled Displays 

      Correa, Wagner T.; Klosowski, James T.; Silva, Claudio T. (The Eurographics Association, 2002)
      We present a sort-first parallel system for out-of-core rendering of large models on cluster-based tiled displays. The system is able to render igh-resolution images of large models at interactive frame rates using ...
