  • A parametric-space-based scan-line algorithm for rendering of bicubic surfaces 

    Pueyo Sánchez, Xavier; Brunet Crosa, Pere (1987)
    Article
    Open Access
    A novel scan-line algorithm for displaying bicubic surfaces is presented. Patches are decomposed on regions of constant sign of the z component of the normal before the scan process. Most of the computations are done in ...
  • Fitting a two-joint orthogonal chain to a point set 

    Díaz-Báñez, José Miguel; López, Mario A.; Mora Giné, Mercè; Seara Ojea, Carlos; Ventura, Inmaculada (2011-04)
    Article
    Open Access
    We study the problem of fitting a two-joint orthogonal polygonal chain to a set S of n points in the plane, where the objective function is to minimize the maximum orthogonal distance from S to the chain. We show that this ...
