| 摘 要： | 本文介绍由任意设置的散乱数据点给定的复杂曲面模型，按整体ＶＣ~１连续的几何特征构造非平面域Ｂｅｒｎｓｔｅｉｎ－Ｂｅｚｉｅｒ三角参数曲面的一种方法。可处理非凸边界、孔洞或多值的曲面造型和空间三角网格自动剖分，并提供一个偏差比率不大的简单判别式，有效地提高了算法效率。

| Abstract: | A new method to construct a non-planar complicated surface with global VC1continuity over given arbitrary scattered data points is presented in this paper. The surface modeling with the non-convex edge, a hole and multi-value and automatic subdivision of triangular nets can be realized effectively. |
