Abstract

L'invention concerne un système et un procédé permettant de faire coïncider une surface à multiples facettes avec une continuité de courbure dans un système de modélisation graphique. Selon les modes de réalisation préférés, on utilise des algorithmes améliorés pour l'adaptation de la surface tangentielle et l'adaptation de la surface de courbure, ce qui permet d'améliorer la continuité entre une surface donnée et au moins une surface adjacente.
