圆边

In our algorithm, 3D object patch in which user is interested is embedded to the circular disk on the plane. We must consider similarity between 3D patch and 2D disk.

本论文之摊平方式，主要是将使用者选定好之三维多面体表面区域，摊平至二维圆盘上，圆盘之圆周其实是一个多边形，边数和边长分别来自於三维物体边界之边数和边长比例。

The first one is to generate the circle for each borderline segment of the component by considering the segment length and the prescribed tolerance value. If this is not the case, the borderline segment will be equally divided into halves until the obtained circle satisfies the tolerance value over the whole borderlines of the component. The basic idea of the last two algorithms aims at covering the domain occupied by the component as much as possible. The circle generation is carried out sequentially from salient angle to the sector formed by the salient angle till the uncovered borderline segments of the component. Particularly, the three-step algorithm with gap allows that the generated circles are distributed with gap along the component contour.

二分法利用组件各边长度和设置的容差大小得到该边的候选包络圆，若该圆不满足组件所有边的容差要求，则将该边不断地对分，直至所得到的包络圆满足各边的容差要求；三步划分法和带间隙的改进三步划分法则以组件区域为划分对象，依次对组件多边形凸顶角、凸扇形区和多边形各边剩余线段划分包络圆，且带间隙的改进三步划分法则允许包络圆在组件边界上以适当的间隙分布。
