    • 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 ...

    • 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 ...

    • Label Placement for Outliers in Scatterplots 

      Mumtaz, Haris; Garderen, Mereke van; Beck, Fabian; Weiskopf, Daniel (The Eurographics Association, 2019)
      In many application scenarios, outliers can be associated with specific importance for various reasons. In such cases, labeling outliers is important to connect them to the actual semantics of the respective entity. In ...

    • Labeled Facets: New Surface Texture Dataset 

      Ganapathi, Iyyakutti Iyappan; Werghi, Naoufel (The Eurographics Association, 2022)
      Object detection, recognition, segmentation, and retrieval have been at the forefront of 2D and 3D computer vision for a long time and have been utilized to address various problems in interdisciplinary domains. The 3D ...

    • Labs and Framework for 2D Content Manipulation

      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.
