摘要
提出一定位点用于有理三次Bezier曲线的计算机交互设计.定位点具有肩点在设计曲线时的一切优点[4],同时又具有更大的存在范围。
A method to determine the locating point in convex hull of four control points pertaining to a rational cubic Bezier curve is presented.Comparing to the shoulder point in (Forrest,1980),the locating point exists in a larger field and offers more flexibility in controlling the shape of curves on computer.
