    • Real time positioning system based on active stereo and facial features identification 

      Frosio, Iuri; Lanzarotti, Raffaella; Campadelli, Paola; Ferrigno, Giancarlo; Borghese, N. Alberto (Eurographics Association, 2003)
      We propose a new system for patient’s head positioning for radiology and radiotherapy. The system is constituted of two low-cost digital cameras and a digital projector. As a first step a bright pattern is projected onto ...

    • Resampling structured grids into regular ones 

      Dimitrov, Leonid I.; Kolcun, Aleksej; Sramek, Milos (Eurographics Association, 2003)
      Structured grids and some of their applications in natural sciences are discussed. The problem of their visualization and quantitative evaluation is considered and possible ways for its solution sketched. Resampling a ...

    • A Spatial Representation for Ray-Scene Intersection Test Improvement in Complex Scenes 

      Revelles, J.; Aguilera, N.; Aguado, J.; Lastra, M.; Garcia, R.; Montes, R. (Eurographics Association, 2003)
      We present a spatial representation based on a hierarchical structure using the well-known spatial indexing structure called octree. There are very useful spatial representations for scenes whose objects can be distributed ...

    • Virtual Modelling 

      Kiss, Szilárd; Nijholt, Anton; Zwiers, Job (Eurographics Association, 2003)
      We concentrate our efforts on building virtual modelling environments where the content creator uses controls (widgets) as an interactive adjustment modality for the properties of the edited objects. Besides the advantage ...

    • VR Game Interfaces for Interaction onto 3D Display 

      Choi, Jeong-Dan; Jang, Byung-Tae; Hwang, Chi-Jeong (Eurographics Association, 2003)
      This paper describes the VR game interfaces for interaction onto 3D display. The challenge we are interested in is how to build and use a low cost 3D display that satisfies semi-immersive requirements and how to coordinate ...
