摘要：
Free-formed or sculptured surfaces in engineering products are frequently constructed from a set of measured 3D data points.C2-(C3-) continuity approach is important in this field. This paper presents a method of rectangular interpolation of given 3D data array which is regularly arranged. The interpolation surface which is constructed by tensor product has desirable properties (second-order or third-order continuity, locality) and is implemented and adjusted easily. Higher order continuity methods are also briefly discussed.
