The algorithm proposed by us for polygonal chains intersection based on the sweep line algorithm is extended, and it is used to detect and delete global self-intersections in the rough offset curve.
拓展了我们已有的平面上单调链求交的扫描线算法，将其应用到初步等距线中的全局自交点和全局无效环的确定上。
At the same time, the curvature of the triangles is introduced to minimize the number of self-intersections detection of the cloth.
同时，在自碰撞检测中，作者利用三角形表面曲率简化计算。
