    • Sampling with Pinwheel Tiles 

      Ahmed, Abdalla G. M. (The Eurographics Association, 2019)
      We outline an adaptive sampling framework based on Conway's pinwheel tiles. It offers a unique feature that the generated tiles have infinite number of orientation angles, minimizing the strong auto-correlations found on ...

    • A Scale-space Approach to the Morphological Simplification of Scalar Fields 

      Rocca, Luigi; Puppo, Enrico (The Eurographics Association, 2023)
      We present a multi-scale morphological model of scalar fields based on the analysis of the spatial frequencies of the underlying function. Morphological models partition the domain of a function into homogeneous regions. ...

    • Scanline Edge-flag Algorithm for Antialiasing 

      Kallio, Kiia (The Eurographics Association, 2007)
      In this paper, a novel algorithm for rendering antialiased 2D polygons is presented. Although such algorithms do exist, they are inefficient when comparing to non-antialiased alternatives. This has lead to a situation where ...

    • Scene Segmentation Based on NURBS Surface Fitting Metrics 

      Pagnutti, Giampaolo; Zanuttigh, Pietro (The Eurographics Association, 2015)
      This paper proposes a segmentation scheme jointly exploiting color and depth data within a recursive region splitting framework. A set of multi-dimensional vectors is built from color and depth data and the scene is segmented ...

    • Scientific Visualization as a Tool for Power Engineering Education 

      Slavik, Pavel; Hrdlicka, Frantisck (The Eurographics Association, 2023)
      This paper deals with the application of scientific visualization methods in the field of power engineering education. Behavior of various parts of a power plant is simulated and the results of these simulations are ...

    • Screen Space Obscurances 

      Sunyer, Nicolau; Gumbau, Jesús; Chover, Miguel; Sbert, Mateu (The Eurographics Association, 2009)
      La simulación de la iluminación indirecta en una escena suele ser muy costosa por lo que normalmente ésta se usa de forma precalculada para escenas estáticas. En este artículo proponemos un algoritmo que aproxima el cálculo ...

    • Screen Space Particle Selection 

      Köster, Marcel; Krüger, Antonio (The Eurographics Association, 2018)
      Analyses of large 3D particle datasets typically involve many different exploration and visualization steps. Interactive exploration techniques are essential to reveal and select interesting subsets like clusters or other ...

    • 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 ...

    • ScWiz: Personalizing Psychotherapy 

      Sá, Marco de; Carriço, Luís; Duarte, Luís; Cruz, David; Torres, Cátia (The Eurographics Association, 2021)
