      Extracting structural information from mesh models is crucial for Simulation Driven Design (SDD) in industrial applications. Focusing on thin-plate CAD mesh models (the most commonly used parts in electronic products such ...
    • Surfel Based Geometry Reconstruction 

      Andersen, Vedrana; Aanæs, Henrik; Bærentzen, Jacob Andreas (The Eurographics Association, 2010)
      We propose a method for retrieving a piecewise smooth surface from noisy data. In data acquired by a scanning process sampled points are almost never on the discontinuities making reconstruction of surfaces with sharp ...
    • Rendering Large Point Datasets with GPU Shaders 

      Aguirre, Hugo; Gutierrez, Diego; Perrin, James S. (The Eurographics Association, 2010)
      This paper demonstrates how programmable GPUs are a powerful tool to display large point datasets at an interactive frame rate. Point datasets are commonly used to analyse and solve complex problems, but rendering them is ...
    • Efficient Image Blur in Web-Based Applications 

      Kraus, Martin (The Eurographics Association, 2010)
      Scripting languages require the use of high-level library functions to implement efficient image processing; thus, real-time image blur in web-based applications is a challenging task unless specific library functions are ...
    • ID-Based Rendering of Silhouettes on GPU 

      Diktas, Engin Deniz; Sahiner, Ali Vahit (The Eurographics Association, 2010)
      When rendering object-silhouettes preprocessing is generally done primarily on the CPU. To this end primitive normals must be made consistent and the silhouette-edges need to be extracted every time the view-point is ...
    • Anisotropic Kuwahara Filtering with Polynomial Weighting Functions 

      Kyprianidis, Jan Eric; Semmo, Amir; Kang, Henry; Döllner, Jürgen (The Eurographics Association, 2010)
      In this work we present new weighting functions for the anisotropic Kuwahara filter. The anisotropic Kuwahara filter is an edge-preserving filter that is especially useful for creating stylized abstractions from images or ...
    • Screen Space Re-Rendering for the Simulation of Concert Lighting 

      Stephenson, Ian; Scanlan, Liam (The Eurographics Association, 2010)
      The visualisation of modern concert lighting requires complex illumination models to be calculated at interactive frame rates. Each light may have 20 or more parameters which are all changing in real time. Here we present ...
    • Diffusion and Fractional Diffusion Based Image Processing 

      Blackledge, Jonathan Michael (The Eurographics Association, 2009)
      We consider the background to describing strong scattering in terms of diffusive processes based on the diffusion equation. Intermediate strength scattering is then considered in terms of a fractional diffusion equation ...
    • Uncertain Flow Visualization using LIC 

      Osorio, Rodolfo S. Allendes; Brodlie, Ken W. (The Eurographics Association, 2009)
      In this paper we look at the Line Integral Convolution method for flow visualization and ways in which this can be applied to the visualization of two dimensional, steady flow fields in the presence of uncertainty. To ...
