By making use of the distance map and introducing a volume spline interpolation algorithm, a set of control points were selected and therefore the conflict areas were adjusted with good effect.

进一步利用得到的距离图，并引入体样条插值算法，选择合适的控制顶点，完成对标准冠牙合面与对颌牙牙合面的冲突区域的调整。

The control points of the B3-spline to be constructed are computed simply by the vertices of the given polygon.

在算法中，所有的B3样条曲线的控制点可以通过对多边形的顶点简单计算产生。

A necessary and sufficient condition is derived for the existence of monotone and convex interpolation by a cubic spline with an additional knot inserted between each pair of data points.

本文给出用三次样条在两两节点之间引进一个外加节点的条件下，存在凸而单调的插值的充分必要条件。
