      Geometrical algorithms have been the main subject of research in the field of real time sound rendering. These algorithms are variants of the image source and ray tracing algorithms, enhanced with improvements that speed ...

    • Gesture Coordination in Collaborative Tasks through Augmented Feedthrough 

      Simard, Jean; Ammi, Mehdi (The Eurographics Association, 2010)
      This article explores the use of haptic feedback for interpersonal communication in Collaborative Virtual Environments. The investigated approach enables the improvement of communication and coordination during closely ...

    • Global Landmarks Do Not Necessarily Improve Spatial Performance in Addition to Bodily Self-Movement Cues when Learning a Large-Scale Virtual Environment 

      Meilinger, Tobias; Schulte-Pelkum, Jörg; Frankenstein, Julia; Berger, Daniel; Bülthoff, Heinrich H. (The Eurographics Association, 2015)
      Comparing spatial performance in different virtual reality setups can indicate which cues are relevant for a realistic virtual experience. Bodily self-movement cues and global orientation information were shown to increase ...

    • A GPU-Based Framework of Photometric Uniformity for Multi-Projector Tiled Display 

      Yuan, Guodong; Qin, Kaihuai (The Eurographics Association, 2007)
      In this paper, we firstly propose a partial-sampling scheme to measure the intensity transfer function of a projector. Secondly, we implement the computation of luminance surface by rendering a texture rectangle on GPU. ...

    • GraphTracker: A Topology Projection Invariant Optical Tracker 

      Smit, F. A.; Rhijn, A. van; Liere, R. van (The Eurographics Association, 2006)
      In this paper, we describe a new optical tracking algorithm for pose estimation of interaction devices in virtual and augmented reality. Given a 3D model of the interaction device and a number of camera images, the primary ...

    • Haptic Display for a Virtual Reality Simulator for Flexible Endoscopy 

      Körner, Olaf; Männer, Reinhard (The Eurographics Association, 2002)
      A simulation system for flexible endoscopy is described, based on virtual reality techniques. The physician moves the flexible endoscope inside a pipe, in which forces are applied to it. In addition the navigation wheels ...
