      Whitlock, Brad; Favre, Jean M.; Meredith, Jeremy S. (The Eurographics Association, 2011)
      There is a widening gap between compute performance and the ability to store computation results. Complex scientific codes are the most affected since they must save massive files containing meshes and fields for offline ...

    • Parallel Mesh Clustering 

      Chiosa, Iurie; Kolb, Andreas; Cuntz, Nicolas; Lindner, Marvin (The Eurographics Association, 2009)
      Fast and qualitative clustering of large polygonal surface meshes still remains one of the most demanding fields in mesh processing. Because existing clustering algorithms are very time-consuming, the use of parallel ...
    • Parallel Methodologies for a Micropolygon Renderer 

      Bolstad, Mark A. (The Eurographics Association, 2014)
      This paper compares the performance of three different methodologies for a multi-threaded micropolygon-based renderer. We extend the REYES [AG99] algorithm for multi-threaded rendering, which we call CASCADE. CASCADE ...

      Wang, Chaoli; Gao, Jinzhu; Shen, Han-Wei (The Eurographics Association, 2004)
      We present a new parallel multiresolution volume rendering algorithm for visualizing large data sets. Using the wavelet transform, the raw data is first converted into a multiresolution wavelet tree. To eliminate the ...

      This paper describes some efficient parallel performance optimization strategies for large-scale unstructured data visualization on SMP cluster machines including the Earth Simulator in Japan. The three-level hybrid ...
    • Parallel Progressive Mesh Editing 

      Derzapf, Evgenij; Grund, Nico; Guthe, Michael (The Eurographics Association, 2014)
      Highly detailed models are commonly used in computer games and other interactive rendering applications. Intuitive editing methods are thus also required in addition to rendering algorithms. Progressive meshes are often ...
    • Parallel Reflective Symmetry Transformation for Volume Data 

      Hong, Yuan; Shen, Han-Wei (The Eurographics Association, 2007)
      Many volume data possess symmetric features that can be clearly observed, for example, those existed in diffusion tensor image data sets. The exploitations of symmetries for volume data sets, however, are relatively limited ...
