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

    Rodríguez González, Omar; Franquesa Niubó, Marta (2005-05)
    Report de recerca
    Accés obert
    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 ...
