An Improved Algorithm for the Generation of Nonparametric Curves

摘要: Generation of curves using incremental steps along fixed coordinate axes is important in such diverse areas as computer displays, digital plotters, and numerical control. Direct implementation a nonparametric representation curve, f(x, y) = 0, has been shown to be attractive for generation. The algorithm this paper developed directly from the allows taken any point adjacent current one, uses decision variables closely related an error criterion. Consequently, more general produces closer actual curve than do previously reported algorithms.
