Abstract
This paper presents a global method for approximation and/or construction of surfaces using constraints. The method is based on a min max problem which describes approximation and differential geometric characteristics, constrained in order to achieve desired geometrical effects. The numerical solution of the problem takes full advantage of the Finite-Elements method and of constrained optimization algorithms. [ABSTRACT FROM AUTHOR]
