      This paper presents a new approach to simplify 3D binary images and general orthogonal pseudo-polyhedra (OPP). The method is incremental and produces a level-of-detail sequence of OPP, where any object of this sequence ...
    • LOD visibility culling and occluder synthesis 

      Andújar Gran, Carlos Antonio; Saona Vázquez, Carlos Luis; Navazo Álvaro, Isabel (2000-01)
      Report de recerca
