    • Lightweight material acquisition using deep learning 

      Deschaintre, Valentin (2019-11)
      Whether it is used for entertainment or industrial design, computer graphics is ever more present in our everyday life. Yet, reproducing a real scene appearance in a virtual environment remains a challenging task, requiring ...
    • Limit Shapes - A Tool for Understanding Shape Differences and Variability in 3D Model Collections 

      Huang, Ruqi; Achlioptas, Panos; Guibas, Leonidas; Ovsjanikov, Maks (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We propose a novel construction for extracting a central or limit shape in a shape collection, connected via a functional map network. Our approach is based on enriching the latent space induced by a functional map network ...
    • Line Art Colorization Based on Explicit Region Segmentation 

      Cao, Ruizhi; Mo, Haoran; Gao, Chengying (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Automatic line art colorization plays an important role in anime and comic industry. While existing methods for line art colorization are able to generate plausible colorized results, they tend to suffer from the color ...
    • A line clipping algorithm and its analysis 

      Krammer, Gergely (Blackwell Science Ltd and the Eurographics Association, 1992)
      One of the classical problems of Computer Graphics: line clipping against a rectangle is revisited. Coordinate raster refinement and some unusual forms of the parametric equation of the line are used to develop formulae ...
    • Line Clipping Using Semi-Homogeneous Coordinates 

      Nielsen, Hans Peter (Blackwell Science Ltd and the Eurographics Association, 1995)
      The dual intersection test is described. It is a new method for deciding whether a line intersects a window. The concept of semi-homogeneous coordinates is introduced. It allows us to define line segments in projective ...
    • Line Drawings vs. Curvature Shading:Scientific Illustration of Range Scanned Artefacts 

      Hörr, Christian; Brunnett, Guido; Vix, Christian (The Eurographics Association, 2010)
      For scientific archaeological illustrations, pen-and-ink drawings are traditionally the most prevalent type. Over the years, drawing styles have substantially changed several times and even today there is basically no ...
    • Line Integral Convolution for Real-Time Illustration of Molecular Surface Shape and Salient Regions 

      Lawonn, Kai; Krone, Michael; Ertl, Thomas; Preim, Bernhard (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a novel line drawing algorithm that illustrates surfaces in real-time to convey their shape. We use line integral convolution (LIC) and employ ambient occlusion for illustrative surface rendering. Furthermore, ...
    • Line Integration for Rendering Heterogeneous Emissive Volumes 

      Simon, Florian; Hanika, Johannes; Zirr, Tobias; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Emissive media are often challenging to render: in thin regions where only few scattering events occur the emission is poorly sampled, while sampling events for emission can be disadvantageous due to absorption in dense ...
    • Line Sampling for Direct Illumination 

      Billen, Niels; Dutré, Philip (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Computing direct illumination efficiently is still a problem of major significance in computer graphics. The evaluation involves an integral over the surface areas of the light sources in the scene. Because this integral ...
