Abstract:In the paper,a new approximating subdivision scheme is presented for quadrilateral nets with 4-valence topology which generates the limit surface of C(1) in the limit at the regular face and quasi-tangent plane continuous at the irregular rigion. The main advantage of the scheme comparing with other algorithms is limit surfaces generated by the scheme can hold the shape of initial control polyhedra better than others. So the criterion satisfies important requirements for practical applications in computer graphics and engineering.
