摘要
曲线的设计与修改是CAD/CAM和数控技术研究的一个重要课题,具有广泛的应用背景。为了满足表示和设计复杂自由曲线的需求,论文构造了一类基于指数函数的曲线-E曲线,给出了基函数及E曲线的定义与性质。通过研究发现,所构造的E曲线具有Bézier曲线类似的一系列优良性质。
Design and modification of curves is a significant research subject in the field of CAD/CAM and numerical control technology and has wide backgrounds of application.In order to meet the need of representing and designing complicated free curves,a new curves based on exponential functions-E curve is constructed,and definitions and properties of its basis function and E curve are presented.It is obvious that E curve owes the same excellent properties with Bézier curve.
