摘 要: | In the application of CAD/CAM. the target form of a curve, which is used for plotting or as the data supplied for CAM, is s set of points on (or near by) the curve,Using the subdivision algorithm, the procedure of curve generation from Control points→Mathematical form of the curve→Points on(or near by) the curve which is used in most systems for curve design, is simplified in this paper to Control points→Points on(or near by) the curve. We also discuss the conditions of shape preserving, polynomial reproducing, continuity as well as the convergent properties of the target curve.
