We propose a method to generate a surface from point cloud or feature curves. This paper describes a surface patch which is obtained by composing the near-field term of the analytic solution of partial differential equation. Due to the property of near-field effect, an arbitrary curve can be used to specify the boundary shape of the patch. We also present a concept to generate a product model from point cloud or designer's sketch. By recognizing feature curves of the object, these curves are used to express the boundary curve of our patch, and then smooth surfaces are generated between these boundary curves. In this paper, a 2-sided patch generation method and its examples are presented.
