The principles of single contour connection, furcation processing and triangular patch division of end face have been introduced in great detail with specific algorithms.
首先详细地介绍了单轮廓连接、 分叉处理及端面三角面片剖分原理，同时给出相关具体算法。

Then we define the boundary strength function and the feature boundary of each patch, to construct a deformation contour on the patch's boundary.
