In this work, we use some results concerning the connection between blossoms and splines, especially those related to the smoothness conditions to develop an algorithm for constructing on an arbitrary triangulation a $C^2$ spline approximant with minimal degree. Numerical tests are presented to illustrate the theoretical results.

在这项工作中，我们使用一些有关花朵和样条之间的连接的结果，尤其是那些与光滑度条件有关的结果，来开发一种用于构造任意三角剖分算法的算法。 $C^2$最小程度的样条曲线近似值。数值试验表明了理论结果。
