    • Visualizing Climate Change: the Potential of Dome Presentations as a Tool for Climate Communication 

      Neset, Tina-Simone S.; Wibeck, Victoria; Uhrqvist, Ola; Johansson, Jimmy (The Eurographics Association, 2010)
      This study presents the outline of a climate visualization programme directed to various target groups that was presented in a dome environment. The efforts of climate and visualization researchers to jointly develop ...
    • Towards an Academic Praxis for Domed Virtual Environments 

      Carss, Peter (The Eurographics Association, 2010)
      This paper sets out the current state of activities for the domed virtual environment located within the University of Plymouth, UK. Some of these activities have arisen through reactions to demands on the dome. Some, ...
    • DomeView: A Tool for Digital Planetariums 

      Silva, M. A.; Fernandes, António Ramires; Pedrosa, A. (The Eurographics Association, 2010)
      The content produced for fulldome projection is usually made in a frame (the master) with a format corresponding to a projection of the dome on a plane, commonly the fisheye projection. Due to the distortions involved, ...
    • Interactive 3D Stereoscopic Dome with Automatic Calibration 

      Dingeldey, Felix; Schiewe, Manuel; Gerhardt, Jérémie; Ahlers, Kay-Ingo; Haulsen, Ivo (The Eurographics Association, 2010)
      In recent years, the advances in projection technology and the increasing rendering capacity of modern computers allowed the development of immersive digital domes. Digital dome systems are not limited to planetariums, but ...
    • Progress in Rendering and Modeling for Digital Planetariums 

      Magnor, Marcus; Sen, Pradeep; Kniss, Joe; Angel, Edward; Wenger, Stephan (The Eurographics Association, 2010)
      Contemporary challenges in the production of digital planetarium shows include real-time rendering realism as well as the creation of authentic content. While interactive, live performance is a standard feature of professional ...
    • Reinterpretable Imager: Towards Variable Post-Capture Space, Angle and Time Resolution in Photography 

      Agrawal, Amit; Veeraraghavan, Ashok; Raskar, Ramesh (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      We describe a novel multiplexing approach to achieve tradeoffs in space, angle and time resolution in photography. We explore the problem of mapping useful subsets of time-varying 4D lightfields in a single snapshot. Our ...
    • Fast High-Dimensional Filtering Using the Permutohedral Lattice 

      Adams, Andrew; Baek, Jongmin; Davis, Myers Abraham (The Eurographics Association and Blackwell Publishing Ltd, 2010)
      Many useful algorithms for processing images and geometry fall under the general framework of high-dimensional Gaussian filtering. This family of algorithms includes bilateral filtering and non-local means. We propose a ...
