    • Flexible Interaction with Large Point-Based Datasets 

      Rosiuta, A.; Reina, G.; Ertl, T. (The Eurographics Association, 2006)
      We present an application for interacting with large, point-based datasets built with commodity off-the-shelf hardware. Our system works on ordinary workstations with mouse and keyboard interaction as well as on immersive ...
    • Augmented Reality with Multilayer Occlusion 

      Feng, Yan; Chen, Yimin (The Eurographics Association, 2006)
      An algorithm for realizing multilayer occlusion in augmented reality (AR) is presented in this paper. We have designed a special scene graph tree comprised of some special nodes, namely EMO nodes. According to the location ...
    • A Mixed Reality Anatomy Teaching Tool 

      Thomas, Rhys G.; John, Nigel W.; Lim, Ik Soo (The Eurographics Association, 2006)
      In this paper we present an inexpensive Mixed Reality software tool for training medical students in anatomy. The software integrates the ARToolkit and Visualization Toolkit (VTK) to create a novel interactive environment ...
    • ATIP: A Tool for 3D Navigation inside a Single Image with Automatic Camera Calibration 

      Boulanger, Kevin; Bouatouch, Kadi; Pattanaik, Sumanta (The Eurographics Association, 2006)
      Automatic Tour Into the Picture (ATIP) is an extension of the Tour Into the Picture method [HAA97] that allows an approximative but visually convincing 3D walk-through inside a single image by rendering a box textured using ...
