Abstract: In order to solve the problem of constraints in MRA modeling, based on the principle of energy method to solve MRA constraints, the idea of wavelet constraints transform is proposed. Since B-spline curve/surface constraints can be de-noted by control points and different resolution control points can be expressed each other by wavelet transform, constraint condition in different resolution can be translated to a single resolution (high resolution), then based on MRA characters and energy method, at the beginning of optimization lowest resolu-tion control points are used, and because of few control points in the lowest resolution, the speed of optimization is greatly improved.
