  • A new sphere-tree generation method to speed up the collision detection pipeline 

    Rodríguez González, Omar; Franquesa Niubó, Marta (2005-05)
    External research report
    Open Access
    In this paper, a novel sphere-tree generation method used for collision detection is proposed. Using existing consumer-level graphics cards and its programmable graphics processing units (GPU) a sphere-tree is constructed ...
  • Analysis of methods for generating octree models of objects from their silhouettes

    Reconstructing 3D models from their projection images has been an interesting research topic in computer vision and geometric modeling. In this paper, we review several methods that generate octree models of objects from ...
  • BOCST: Branch On-Collide Sphere-Trees 

    Rodríguez González, Omar; Franquesa Niubó, Marta (2005-10)
    External research report
    Open Access
    In this paper, a fast sphere-tree generation method used for collision detection called Branch On-collide Sphere-trees is proposed. Using the video card graphic processing unit (GPU), a sphere-tree is constructed in real-time ...
  • Collision prediction using MKtrees 

    Franquesa Niubó, Marta; Brunet Crosa, Pere (2004)
    Conference report

    K dimensional tree data structure(Multiresolution Kdtree, MKtree) is introduced. In a complex scene containing a high number of individual objects, the MKtree represents a hierarchical subdivision of the scene objects that ...
  • Hierarchical structuring of scenes with MKtrees 

    Rodríguez González, Omar; Franquesa Niubó, Marta (2005-01)
    External research report
    Open Access
    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 ...

  • Sphere-trees generation as needed in real time to speed up collision detection 

    Franquesa Niubó, Marta; Rodríguez González, Omar (2005-11)
    External research report
    Open Access
    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 ...
