TitleSemi-implicit representations of surfaces in , resultants and applications
Author(s) Laurent Buse, Andre Galligo
TypeArticle in Journal
AbstractIn this paper we introduce an intermediate representation of surfaces that we call semi-implicit. We give a general definition in the language of projective complex algebraic geometry, and we begin its systematic study with an effective view-point. Our last section will apply this representation to investigate the intersection of two bi-cubic surfaces; these surfaces are widely used in Computer Aided Geometric Design.
