      This work presents an interactive Graphical User Interface used to display and manipulate collection of large XML documents. It relies on a geometrical model that combines hierarchical and sequential representations. In ...

    • 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 ...

    • Polygon-Polygon Collision Detection in 2D 

      Jiménez Delgado, Juan J.; Segura Sánchez, Rafael J.; Feito Higueruela, Francisco R. (Eurographics Association, 2003)
      Collision detection between moving objects is an open question which raises major problems concerning its algorithmic complexity. In this paper we present a polygon collision detection algorithm which uses polygon decomposition ...

    • Certosa virtual museum: a dynamic multilevel desktop VR application 

      Calori, L.; Diamanti, T.; Guidazzoli, A.; Liguori, M. C.; Mauri, M. A.; Valentini, L. (Eurographics Association, 2003)
      Starting from the exigencies of restoration, safeguard and promotion set by Bologna City Council for its Museum of the Certosa Cemetery, a multilevel application has been developed. Its main features are dynamic generation ...

    • GreenArt: A Tool for Non-Photorealistic Rendering of Plants and Trees 

      Campos, C.; Quirós, R.; Huerta, J.; Camahort, E.; Lluch, J.; Vivo, R. (Eurographics Association, 2003)
      Plant and tree rendering is critical to many computer graphics applications, like interactive walkthroughs, architectural presentations, entertaintment and computer games. Current research focuses on realistic modeling and ...

    • Parametric Foveation for Progressive Texture and Model Transmission 

      Cheng, Irene; Basu, Anup; Pan, Yixin (Eurographics Association, 2003)
      Spatially varying sensing (foveation) has been used in many different areas of Computer Vision, such as image compression and video teleconferencing and in perceptually driven Level of Detail (LOD) representations in ...

    • Predictive fixed-frame rate tessellation of NURBS surfaces
