      We present an algorithm for rendering complex scenes using occlusion queries to resolve visibility. To organize objects in the scene, the algorithm uses a ternary tree which is dynamically modified according to the current ...

    • Enhanced Hand Manipulation for Efficient and Precise Positioning and Release 

      Osawa, N. (The Eurographics Association, 2005)
      Direct manipulation by hand is important in that it allows users to manipulate 3D virtual objects easily in an immersive virtual reality environment. Although direct hand manipulation is easy to understand and easy to use ...

    • Evaluation of Collaborative Construction in Mixed Reality 

      Boschker, Breght R.; Mulder, Jurriaan D. (The Eurographics Association, 2005)
      Collaborative virtual and augmented reality are an active area of research and many systems supporting collaboration have been presented. Just like there are many different systems for VR and AR, there are many different ...

    • Experience of a Hybrid Information Space between an Outdoor Field and an Immersive Virtual World 

      Ogi, T.; Fujise, T. (The Eurographics Association, 2005)
      This paper proposes the concept of the hybrid information space that integrates the information seamlessly between the real world and the virtual world, and the prototype system was developed in which the immersive virtual ...

    • Feature Tracking in VR for Cumulus Cloud Life-Cycle Studies 

      Griffith, E. J.; Post, F. H.; Koutek, M.; Heus, T.; Jonker, H. J. J. (The Eurographics Association, 2005)
      Feature tracking in large data sets is traditionally an off-line, batch processing operation while virtual reality typically focuses on highly interactive tasks and applications. This paper presents an approach that uses ...

    • A Game Engine-based Multi-Projection Virtual Environment with System-Level Synchronization 

      Hashimoto, Naoki; Ishida, Yoshihiko; Sato, Makoto (The Eurographics Association, 2005)
      In multi-projector displays, which surround users with high-resolution images, a PC-Cluster is often used for realistic and real-time image generation. However, developing applications that support parallel processing on ...

    • Imperceptible Projection Blanking for Reliable Segmentation within Mixed Reality Applications 

      Kuechler, M.; Kunz, A. (The Eurographics Association, 2005)
      Applications that run in a projection-based mixed reality environment frequently require simultaneous image acquisition of the user by a camera. For later processing, very often a segmentation of the user s image is required, ...
