Spline 的原意是造船放样用的有弹性的板条。好象我们绘图常用的有机玻璃板尺,可以用来绘制曲线,即通过适当控制弯出一条通过若干指定点的曲线。

我曾在造船厂做过工。我们用各种厚度和宽度的有机玻璃板条,来刮平船体新抹的油灰,板条靠紧事先做好的控制线 ( contral lines ) 上,就可得到由这些控制线确定的平滑曲面。

制图学中的 spline 的作用原理是同样的。Spline 上的任何一点的变化,都会牵动其他点乃至整个曲线变化,因此曲线永远是平滑流畅的。

B样条是样条曲线的一种,其优点是局部的修改不会引起样条形状变化的远距离传播,也就是说修改样条的某些部分时,不会过多地影响曲线的其它部分。
