      Liu, Baoquan; Clapworthy, Gordon J.; Dong, Feng; Wu, Enhua (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Interactive isosurface visualisation has been made possible by mapping algorithms to GPU architectures. However, current state-of-the-art isosurfacing algorithms usually consume large amounts of GPU memory owing to the ...

    • Parallel Multipipe Rendering for Very Large Isosurface Visualization 

      Udeshi, Tushar; Hansen, Charles D. (Springer and The Eurographics Association, 1999)
      In exploratory scientific visualization, isosurfaces are typi- cally created with an explicit polygonal representation for the surface using a technique such as Marching Cubes. For even moderate data sets, Marchching Cubes ...

    • Parallel Ray Casting of Visible Human on Distributed Memory Architectures 

      Bajaj, Chandrajit; Ihm, Insung; Koo, Gee-bum; Park, Sanghun (Springer and The Eurographics Association, 1999)
      This paper proposes a new parallel ray-casting scheme for very large volume data on distributed-memory architectures. Our method, based on data compression, attempts to enhance the speedup of parallel rendering by quickly ...

    • Parametric Visualization of High Resolution Correlated Multi-spectral Features Using PCA 

      Broersen, Alexander; Liere, Robert van; Heeren, Ron M. A. (The Eurographics Association, 2007)
      An imaging mass spectrometer is an analytical instrument that can determine the spatial distribution of chemical compounds on complex surfaces. The output of the device is a multi-spectral datacube; a three-dimensional ...

    • Particle Level Set Advection for the Interactive Visualization of Unsteady 3D Flow 

      Cuntz, Nicolas; Kolb, Andreas; Strzodka, Robert; Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Typically, flow volumes are visualized by defining their boundary as iso-surface of a level set function. Grid-based level sets offer a good global representation but suffer from numerical diffusion of surface detail, ...

    • Particle Tracing in σ-Transformed Grids using Tetrahedral 6-Decomposition 

      Sadarjoen, Ari; Boer, Alex J. de; Post, Frits H.; Mynett, Arthur E. (The Eurographics Association, 1998)
      Particle tracing in curvilinear grids often employs decomposition of hexahedral cells into 5 tetrahedra. This method has shortcomings when applied to sigma-transformed grids, a grid type having strongly sheared cells, ...

    • Particle Tracing on Sparse Grids 

      Teitzel, Christian; Grosso, Roberto; Ertl, Thomas (The Eurographics Association, 1998)
      These days sparse grids are of increasing interest in numerical simulations. Based upon hierarchical tensor product bases, the sparse grid approach is a very e cient one improving the ratio of invested storage and computing ...
