  • Hoops: 3D curves as conservative occluders for cell visibility 

    Brunet Crosa, Pere; Navazo Álvaro, Isabel; Rossignac, Jarek; Saona Vázquez, Carlos Luis (North Holland, 2001-08)

    Most visibility culling algorithms require convexity of occluders. Occluder synthesis algorithms attempt to construct large convex occluders inside bulky non-convex sets. Occluder fusion algorithms generate convex occluders ...
  • Integrating occlusion culling and levels of detail through hardly-visible sets 

    Andújar Gran, Carlos Antonio; Saona Vázquez, Carlos Luis; Navazo Álvaro, Isabel; Brunet Crosa, Pere (North Holland, 2000-12)

    Occlusion culling and level-of-detail rendering have become two powerful tools for accelerating the handling of very large models in real-time visualization applications. We present a framework that combines both techniques ...
  • LOD visibility culling and occluder synthesis 

    Andújar Gran, Carlos Antonio; Saona Vázquez, Carlos Luis; Navazo Álvaro, Isabel (Elsevier, 2000-11)
    Article
    Open Access
    Level-of-detail occlusion culling is a novel approach to the management of occluders that can be easily integrated into most current visibility culling algorithms. The main contribution of this paper is an algorithm that ...
  • The visibility octree: a data structure for 3D navigation 

    Saona Vázquez, Carlos Luis; Navazo Álvaro, Isabel; Brunet Crosa, Pere (1999-05)
    Article

    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 ...
