摘要
四点插值细分法（简称四点法）是一种离散插值方法，在曲线和曲面造型中有较广泛的应用。本文给出了四点法的一个保凸算法。
The four-point interpolation scheme (four-point scheme) is a kind of discrete interpolation scheme. It has been applied widely in curve and surface modeling. In this paper,we give a convexity-preserving algorithm of the four- point scheme.
