摘要：

The paper presents a B-spline Boolean-sum approach to the representation of Coons-Gordon-type surfaces; a bivariate B-spline interpolant can be constructed from an adequate superposition of univariate B-spline interpolants by the Boolean sum being formed in the same way as are Coons-Gordon surfaces. Then, a possible way of extending the B-spline Boolean-sum approach to NURBS is discussed for the approximation of Coons-Gordon-type surfaces.
