【Abstract】 An algorithm of point insert based on energy minimization is presented and used to construct an initial surface. It is indicated that all unknown points in the surface can be calculated using this algorithm, and the constructed surface will be smoothness. This algorithm has been successfully used in the design system of NC oriented free surface.更多还原
