This paper describes a method of generating a curved surface by using the data at the arbitrarily distributed points. In this method, the heights of the surface at the rectangular grid points are first-ly estimated from those data at the arbitrarily distributed points, and then a curved surface is generated from the estimated heights at the grid points by using B6zier, B-spline or Coons rectangular patches. For assuring the validity of the method in this paper a curved surface is generated by using the data at the arbitrarily distributed points of ar analytically well-known surface, and the error of the generated surface is analyzed. Since arbitrarily distributed data points can be handled for generating a curved surface, it is possible tp collect more data "from the surface of a clay model with higher curvature.
