Abstract: This paper proposed an algorithm for boundary shape curve fairing and simplification. Compared with the
previous methods, the selected boundary shape curve was faired with non-uniform B-spline wavelets by the new
approach without superfluous control points, because T-mesh can be allowed in the result surface. Some examples
were also presented in this paper to demonstrate the effectiveness of the new algorithm.

Key words: B-spline, wavelet decomposition, boundary shape curve, fairing and simplification
