| Abstract: | A method of fairing B spline
surfaces by wavelet decomposition is investigated. The wavelet decomposition and
reconstruction of quasi uniform bicubic B spline surfaces are described in detail. A method is
introduced to approximate a B spline surface by a quasi uniform one. An error control
approach for wavelet based fairing is suggested. Samples are given to show the feasibility of
the algorithms presented in this paper. The practice showed that the wavelet based fairing is
better than energy based one in case where the number of vertices of the B spline surface is
greater than 1000. The quantitative variance of the approximation error in accordance with the
change of decomposition levels needs to be further explored. |
