Abstract

We propose to extend the corner cutting subdivision schemes from refining control points to refining control curves. Such schemes are relevant to the design of a surface by a family of curves. Our schemes replace averages between two consecutive control points by similar weighted averages between two consecutive curves, based on a geometric correspondence between points on the two curves. We show that the schemes converge under mild conditions on the initial control curves, and derive properties of the limit.
