Title (EN) HYBRID SUBDIVISION IN COMPUTER GRAPHICS
(FR) SUBDIVISION HYBRIDE DE GRAPHIQUES D'ORDINATEUR
Abstract: front page image
(EN)Different limit surfaces are derived from the same initial arbitrary polygon mesh by sequentially combining different subdivision rules. This added freedom allows for the more efficiently modeling of objects in computer graphics including objects and characters with semi-sharp features.
(FR)On calcule différentes surfaces limites à partir de la même maille de polygone initiale arbitraire par combinaison séquentielle de différentes règles de subdivision. Cette liberté ajoutée permet d'effectuer une modélisation plus efficace d'objets dans des graphiques d'ordinateur, y compris des objets et des caractères présentant des caractéristiques semi-précises.
