Abstract

One essential interpolation constraint on subdivision surfaces is curve interpolation. Subdivision surfaces through predefined meshes of curves can now be generated using either variations of existing subdivision schemes or (in our case) polygonal complexes. This paper goes one step further; given a sequence of cross sectional curves (ci), each defined by a uniform cubic B-spline control polygon (cpi), we present
