    • La Caméra Enchantée 

      Rossignac, Jarek (The Eurographics Association, 2017)
      A rich set of tools have been developed for designing and animating camera motions. Most of them optimize some geometric measure while satisfying a set of geometric constraints. Others strive to provide an intuitive graphical ...

      Guo, Hanqi; Di, Sheng; Gupta, Rinku; Peterka, Tom; Cappello, Franck (The Eurographics Association, 2018)
      We design and implement La VALSE-a scalable visualization tool to explore tens of millions of records of reliability, availability, and serviceability (RAS) logs-for IBM Blue Gene/Q systems. Our tool is designed to meet ...
    • A Lab Exercise for 2D Line Clipping 

      Stahl, David (The Eurographics Association, 9-7-2007)
      Line clipping is a fundamental topic in an introductory graphics course. The simplicity and elegance of the classic Cohen-Sutherland 2D Line Clipping Algorithm makes it suitable for implementation by the student in a lab ...
    • A Lab Exercise for Rasterizing Lines 

      Stahl, David (The Eurographics Association, 7-1-2008)
      Rasterizing lines is one of many fundamental topics in an introductory graphics course, with Bresenham's Algorithm particularly well suited for student implementation. By having students complete carefully prepared scaffold ...
    • Labs and Framework for 2D Content Manipulation 

      Paquette, Eric; Barré-Brisebois, Colin; Barras, Jean-François; Bois, Frank Sébastien; Ghaouat, Mohammed El (The Eurographics Association, 18-7-2006)
      Creating and manipulating 2D content is important for computer scientists and requires knowledge in 2D Computer Graphics and Image Processing. A framework and five labs are proposed to help undergraduate students in Computer ...
    • The Labyrinthe of Versailles from 3D desktop to the Oculus Rift 

      Giloth, Copper; Tanant, Jonathan (IEEE, 2015)
      The app ''Labyrinth of Fables'' provides a virtual reality/augmented reality reconstruction of the longlost Labyrinthe of Versailles.
    • A Lagrangian Approach to Dynamic Interfaces through Kinetic Triangulation of the Ambient Space 

      Pons, J.-P.; Boissonnat, J.-D. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, we propose a robust and efficient Lagrangian approach for modeling dynamic interfaces between different materials undergoing large deformations and topology changes, in two dimensions. Our work brings an ...
    • Lagrangian Coherent Structures with Guaranteed Material Separation 

      Germer, Tobias; Otto, Mathias; Peikert, R.; Theisel, H. (The Eurographics Association and Blackwell Publishing Ltd., 2011)
      Given an unsteady flow field, one common way to compute Lagrangian Coherent Structures (LCS) is to extract extremal structures of the Finite Time Lyapunov Exponent (FTLE). Experience has shown that the resulting structures ...
    • Lagrangian Visualization of Flow-Embedded Surface Structures 

      Garth, Christoph; Wiebel, Alexander; Tricoche, Xavier; Joy, Ken; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      The notions of Finite-Time Lyapunov Exponent (FTLE) and Lagrangian Coherent Structures provide a strong framework for the analysis and visualization of complex technical flows. Their definition is simple and intuitive, and ...
    • Lambertian Correction for Rough and Specular Surfaces 

      Robles-Kelly, A.; Hancock, E.R. (The Eurographics Association, 2003)
      This paper describes a method for performing Lambertian reflectance for rough and specular surfaces. Rather than using an existing reflectance model, we present a method for estimating the reflectance function from image ...
    • Landmark-constrained 3-D Histological Imaging: A Morphology-preserving Approach 

      Gaffling, Simone; Daum, Volker; Hornegger, Joachim (The Eurographics Association, 2011)
      The inspection of histological image sequences to gain knowledge about the original three-dimensional (3-D) morphological structure is a standard method in medical research. Its main advantage is that light microscopes ...
    • Landmark-Guided Elastic Shape Analysis of Spherically-Parameterized Surfaces 

      Kurtek, Sebastian; Srivastava, Anuj; Klassen, Eric; Laga, Hamid (The Eurographics Association and Blackwell Publishing Ltd., 2013)
