      Fisseler, Denis; Weichert, Frank; Müller, Gerfrid G. W.; Cammarosano, Michele (The Eurographics Association, 2014)
      Philological research on ancient cuneiform texts with the goal of analyzing and reconstructing manuscripts from a large quantity of available unsorted tablet fragments is a time consuming task. As the number of tablet ...
    • Extending Physical Collections Into the Virtual Space of a Digital Dome 

      Handron, Kerry; Jacobson, Jeffrey (The Eurographics Association, 2010)
      The Earth Theater at the Carnegie Museum of Natural History (Carnegie MNH) in Pittsburgh is an all-digital partial dome display, an immersive theater. Our current offerings include an Egyptian temple, a virtual dinosaur ...
    • Extending the CSG Tree. Warping, Blending and Boolean Operations in an Implicit Surface Modeling System 

      Wyvill, Brian; Guy, Andrew; Galin, Eric (Blackwell Publishers Ltd and the Eurographics Association, 1999)
      Automatic blending has characterized the major advantage of implicit surface modeling systems. Recently, the introduction of deformations based on space warping and Boolean operations between primitives has increased the ...
    • Extending the Design Space of E-textile Assistive Smart Environment Applications 

      Rus, Silvia Dorotheea (2021-06-30)
      The thriving field of Smart Environments has allowed computing devices to gain new capabilities and develop new interfaces, thus becoming more and more part of our lives. In many of these areas it is unthinkable to renounce ...
    • Extending the Immediate Buckling Model to Triangular Meshes for Simulating Complex Clothes 

      Choi, Kwang-Jin; Ko, Hyeong-Seok (Eurographics Association, 2003)
      The immediate buckling model is an essential element for simulating realistic cloth animations without introducing buckling instability. The original model is restricted to structured regular quad meshes, by which its use ...
    • Extending the Scaffold Hunter Visualization Toolkit with Interactive Heatmaps 

      Sturm, Werner; Schäfer, Till; Schreck, Tobias; Holzinger, Andreas; Ullrich, Torsten (The Eurographics Association, 2015)
      In many application areas, large amounts of data arise, which are often hard to interpret or make use of by humans. Interactive visualization can help to overview and explore large amounts of data. An example is in the ...
    • Extending the Working Volume of Projection-based Mixed Reality Systems 

      Splechtna, R.C.; Fuhrmann, A.L. (The Eurographics Association, 2003)
      The working volume of a Mixed Reality (MR) system - which superimposes the real environment with computer- generated virtual content - strongly depends upon the output/display device used. Single screen projection systems ...
