Morning Session: Introductory Material The morning section will focus on the foundations of subdivision, starting with subdivision curves and moving on to surfaces. We will review and compare a...
Surface Design using Locally Interpolating Subdivision Schemes (2007)
Non-uniform multivariate subdivision schemes are constructed, which generate limit functions interpolating some of the initial control points. Our schemes differ from the known interpolatory...
Modified subdivision surfaces with continuous curvature (2006)
we modify the Catmull-Clark limit surface for curvature continuity. (c) Isophotes of the modified C 2 surface. (d-e) A comparison between the isophotes of the original Catmull-Clark surface (d) and...

Filling N-sided Holes Using Combined Subdivision Schemes (2002)
A new method is presented for calculating N-sided surface patches. The algorithm generates a subdivision surface which satisfies arbitrary C(sup 1) boundary conditions. The proposed subdivision...
Trimming for Subdivision Surfaces (2000)
Nathan Litke, Adi Levin, Peter Schröder
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...
Combined Subdivision Schemes for the Design of Surfaces Satisfying Boundary Conditions (1999)
We present a new kind of subdivision schemes, which we call combined subdivision schemes. Such schemes are used to refine a given control net, taking into consideration boundary conditions on the...
Boundary algorithms for subdivision surfaces (1998)
. 1 Abstract In this paper we construct non-uniform bi-variate subdivision schemes that generate surfaces satisfying prescribed boundary conditions. Such a scheme is based on a known uniform...
Piecewise Smooth Subdivision Surfaces With Normal Control
Henning Biermann, Adi Levin, Denis Zorin
In this paper we introduce improved rules for Catmull-Clark and Loop subdivision that overcome several problems with the original schemes (lack of smoothness at extraordinary boundary vertices, folds...
