      Report de recerca
      Accés obert
      MDTL is a textual language created by the Computer Graphics Section of the Language and Information Systems of the Universitat Politecnica de Catalunya. The Computer Graphics Section has several research groups which use ...

    • The Visibility octree. A data structure for 3D navigation 

      Saona Vázquez, Carlos Luis; Navazo Álvaro, Isabel; Brunet Crosa, Pere (1999-06)
      Report de recerca
      Accés obert
      This paper describes the Visibility Octree, a data structure to accelerate 3D navigation through very complex scenes. A conservative visibility algorithm that computes and hierarchically stores the structure at a preprocessing ...

    • Topological constraints in ship design 

      Solano Albajés, Lluís; Gurrea, I; Brunet Crosa, Pere (2000-04)
      Report de recerca
      Accés obert
      In this paper we propose a generic and integrated data structure that is decoupled form the product model database in order to manage and update the geometric elements (parts) related with topological constraints. We ...

    • Topology-reducing surface simplification using a discrete solid representation 

      Andújar Gran, Carlos Antonio; Brunet Crosa, Pere; Ayala Vallespí, M. Dolors (2002-04)
      Article
      Accés restringit per política de l'editorial
      This paper presents a new approach for generating coarse-level approximations of topologically complex models. Dramatic topology reduction is achieved by converting a 3D model to and from a volumetric representation. Our ...

    • Using projective octrees in 3D reconstruction 

      García Diego, Blanca; Brunet Crosa, Pere (1997-11)
      Report de recerca
      Accés obert
      In this paper, the problem of reconstructing a 3D object by means of an octree-like structure with the help of epipolar geometry within a projective framework is addressed. After a brief introduction to the concept ...
