    • Hierarchical structuring of scenes with MKtrees 

      Rodríguez González, Omar; Franquesa Niubó, Marta (2005-01)
      Report de recerca
      Accés obert
      The location of an object or parts of an object in huge environments is of fundamental importance in several research areas. The problem to locate an object or parts of an object in very complex systems (environments ...

    • Methods' analysis for generating octree models of objects from their silhouettes 

      Franquesa Niubó, Marta; Brunet Crosa, Pere (1996-07-29)
      Report de recerca
      Accés obert
      Reconstructing 3D models from their projection images has been an interesting research topic in computer vision and geometric modeling. In this paper, we review methods that generate octree models of objects from their ...
    • MKtree: generation and simulations 

      Franquesa Niubó, Marta; Brunet Crosa, Pere (2002-01)
      Report de recerca
      Accés obert
      The problem to represent very complex systems has been studied by several authors, obtaining solutions based on different data structures. In this paper, a K dimensional tree (Multirresolution Kdtree, ...
    • MKtrees: construction and applications 

      Franquesa Niubó, Marta; Brunet Crosa, Pere (2003-07)
      Report de recerca
      Accés obert
      In this report, a new $ dimensional tree data structure ({emph Multiresolution Kdtree, MKtree}) is introduced. In a complex scene containing a high number of individual objects, the MKtree represents a ...
    • Sphere-trees generation as needed in real time to speed up collision detection 

      Franquesa Niubó, Marta; Rodríguez González, Omar (2005-11)
      Report de recerca
      Accés obert
      In this paper two improvements to speed up collision detection are described. Firstly, a method called oncollide sphere-tree, OCST for short, is presented. This approach works by detecting collisions among models with ...
