With the boundary point and the known adjacent relations, an overall marching procedure can go on and the iteration process stops until the intersection curve is self-closed or reaches the border of the composite surface. In the later case, the marching must be repeated from the starting point in the reverse direction until the intersection curve reaches the other border of the composite surface.

由一个交点出发，通过计算跟踪方向和跟踪步长，迭代计算出下一个精确的交点；利用边界点和近曲面点计算方法，根据曲面片的拓扑关系找到交线所经过的下一张曲面片，从而使跟踪过程继续下去，直至形成封闭交线环而停止该交线段的跟踪，或到达复合曲面的边界后由首交点反向跟踪到达复合曲面的另一边界。
