Trimming for subdivision surfaces
Trimming is an important primitive operation in geometric modeling. It is also the root of many numerical and topological problems in modern NURBS based CAGD systems. In this paper we introduce a new method for trimming subdivision surfaces. It is based on the use of combined subdivision schemes to guarantee exact interpolation of trim curves. The latter ensures, for example, that if two surfac...

متن کاملFast Intersections for Subdivision Surfaces
Subdivision surface intersections can be costly to compute. They require the intersection of high resolution meshes in order to obtain accurate results, which can lead to slow performance and high memory usage. In this paper we show how the strong convex hull property can lead to a method for efficiently computing intersections at high resolutions. Consequently, the method can be used with any ...
متن کاملSubdivision Surfaces for Industrial Design
Subdivision surfaces are a powerful representation for surface modeling and design. While trimmed NURBS representation is widely applied in all CAID (Computer-aided Industrial Design) softwares, subdivision surfaces (SS) have been implemented only in character animation software like Maya and dedicated to entertainment and movies. In this paper a brief review in Subdivision Surfaces application...
متن کاملNecessary Conditions for Subdivision Surfaces
Subdivision surfaces are considered which consist of tri-or quadrilateral patches in a mostly regular arrangement with nitely many irregularities. A sharp estimate on the lowest possible degree of the patches is given. It depends on the smoothness and exibility of the underlying subdivision scheme.
