Abstract
In this article, by generalizing the techniques of Mustafa, Falai and Deng (2006), we estimate the error bounds between the tensor product binary volumetric model and its control polyhedron after k-fold subdivision. Our bounds are expressed in terms of the first-order differences of the initial control point sequences and constants that depend on the subdivision masks.
