摘要

In this paper, we discuss how to obtain the parametric surface of minimal area defined on a rectangular parameter domain among all the surfaces with prescribed entire or partial borders, i.e, the quasi-Plateau problem. An approximation method is presented based on the Multiresolution Analysis (MRA) using B-splines. Four algorithms are proposed according to different cases of the boundary conditions. The solution surfaces can be obtained by solving a system of linear equations of simple and sparse structure. Examples are provided to illustrate that the proposed method is effective and flexible.
