摘要
根据PH曲线的定义,构造了Bézier形式的四次PH曲线,亦称之四次Pythagorean Bézier速端曲线(PB曲线),研究了四次PB曲线特征性质,构造了它的一阶Hermite插值曲线,得到了C1四次Pythagorean Bézier样条曲线。
According to the definition of PH Curves,the quartic PH curves with Bézier form(known as PB curves,i.e.quartic Pythagorean Bézier hodograph curves) are constructed.Then the properties of quartic PB are investigated and the first order Hermite interpolating curves are constructed,from which the C1 quartic Pythagorean Bézier Spline curves are obtained.
